Three advantages for LED advertising module

First one is save electricity.For low price and low quality LED products ,their luminous efficiency is low,lighting consumption is fast,it’s impossible for them to save electricity,on the contrary,high quality LED advertising module can save as many as 50% electricity than normal energy saving fluorescent lamp.

Second is “Save money ”,low price low quality LED products cannot realize “saving electricity” effect ,also with low quality,short lifespan,needs to be maintained and replaced frequently ,not saving,but waste more . High quality LED advertising module can save your money by saving electricity and maintenance cost .according to an investigation by a journalist ,using 8W LED bulb to replace 40W filament lamp ,,8 pcs for each family,lighted 4hrs a day,￥0.6 per kwh,you can save 374 kwhs electricity for one year,that means you will save ￥224 a year.

Last one is “free from worry”,no matter family users or supermarket,hotel and so on commercial users,maintaining and replacing is hard work.

Under the circumstances of high labour cost today,the maintenance cost of lighting products becomes higher and higher .For high quality LED advertising module,it can be used for a long time ,no need to maintain and replaced frequently,to realize the real “free from worry”.

Currently LED advertising module production cost is higher than traditional lighting products ,it’s economic benefit does not embodied in purchasing cost,but reduce down operation cost and maintenance cost by”long lifespan,low energy consumption”, so as to offset the purchasing cost balance.Yayuhong Optoeletronic & Technology here remind dear customers ,to realize real “save money,save electricity,free from worry”,you need to choose both high quality and excellent after sales service .Don’t misguide by low price and salesman.

LED Sign Module is leading the industry fashion

LED light is becoming more and more popularized ,the first advantage is because there are so many color options for LED sign module,providing different choices for different customers. The higher power LED sign module,the higher brightness ,the longer operation time .These products has high brightness and big emitting angle ,fully played advertising effects,and the advertising details won’t be ignored by customers !

led sign module

LED sign module has better publicity effects than traditional advertising methods,higher visibility,the effects will be much more better when night falls.Using LED sign module during night time ,it will shine like stars,people who are far away will be attracted to there,if with placard ,that needs to add some other additional lights so that it can be seen .this will cost more than LED sign module ,more importantly,it cannot be seen in a longer distance,that will greatly reduce down the advertising effects.To compete with industry competitors,you needs to choose LED sign modules when your location is not as good as others,that will bring you a much more better advertising effects.Now there are already many people dedicated in LED sign module wholesale business.LED sign module is one of LED light source ,usually applied in channel letter、lighting signages、light box and so on advertisement lighting.Under normal circumstances it used as back light lighting ! that makes LED sign modules fully adapt to some display characters、signages.These characters and signages can not only shines but also take advertising effects . LED sign module not only  show it’s advantage at night time,but also during daytime.

Cree Launches Industry’s First Driver Compatibility Program for LED Modules

Cree, Inc. (Nasdaq: CREE) introduces the Driver Compatibility Program for its LED products. The new Driver Compatibility Program provides LED lighting manufacturers with a list of drivers that are compatible with Cree® LED modules, as verified through evaluation and testing by Cree. By leveraging the technology and features of third-party drivers, the program enables lighting manufacturers to quickly address the requirements unique to various countries, further differentiate their products and address more applications. 

The first of its kind program allows Cree to extend its LED module warranty to the use of Cree’s LED module with a compatible third-party LED driver. Cree’s LED modules warranty was previously limited to the use of a Cree LED module with a Cree driver. The Driver Compatibility Program demonstrates Cree’s continued commitment to helping LED lighting manufacturers overcome the challenges of bringing high-quality products to market faster. 

“Cree’s Driver Compatibility Program enabled us to find a driver that meets a customer’s specific dimming requirement,” said Fred Farzan, president of Nora Lighting. “Because of the program, we solved the customer’s problem and won the business.”

“We're pleased to take part in Cree’s Driver Compatibility Program, which helps build a larger ecosystem for customers,” said John LaCorte, national sales manager of Thomas Research Products. “It offers a new level of confidence in selecting Cree LED products and compatible, highly reliable LED drivers from Thomas Research Products. This can speed time to market for customers that design LED luminaires.” 

“Cree’s Driver Compatibility Program is yet another way Cree drives LED adoption, enabling everyone to win in the LED revolution,” said Mike Watson, Cree senior director marketing, LED components. “For driver manufacturers, the program provides access to Cree’s customers and products, expanding their market and enabling them to better serve lighting manufacturers. For lighting manufacturers, the program provides greater design flexibility and enables a shorter design cycle to get products to market faster.”

Cree kicks off the Driver Compatibility Program with a range of compatible drivers for the LMH2 LED Module and plans to extend to other LED products later this year; program details can be found at www.cree.com/dcp.

Packaged LED providers diversify into module market

 According to the latest research from IHS, Inc., leading suppliers of LED components are increasingly diversifying, in order to produce LED modules and light engines. Many companies, known only as packaged LED providers in the past, have expanded their product offerings, and are now also supplying LED modules. The competition in this market is particularly diverse, not only because suppliers are located all over the world, but also because of competition from companies with backgrounds in power devices and other backgrounds.

These suppliers are moving into the module market, in order to diversify their portfolio and protect against component LED profit margins potentially lowering further, as the packaged LED market becomes increasingly commoditized. With Chinese companies beginning to gain share, companies in the West and Korea (among others) are moving up the supply chain to minimize the effects of this competition. With modules and light engines becoming more common, there is a growing trend for lighting companies to purchase LED modules, rather than component-packaged LEDs, in order to shorten and simplify the supply chain; however, in-house production by lighting companies is still common and will remain so.

The combined market for LED modules and light engines in lighting applications is projected to reach $1.3 billion in 2014, according to the latest IHS “Next Generation Lighting” report. In addition to providing insight into modules and light engines, the report also features analysis of the emerging markets for LiFi, indoor positioning and OLED.

LED lumionus character is the developing trend for outdoor signages

Directing at the single style、simple function for traditional AD signages,led display luminous characters,also called video signages. LED display luminous characters are using display screen,instead of traditional luminous character,comparing to regular led light box type,it can save as many as 60% or above energy,light weight,easy maintenance,high standard technic process,high brightness display screen which can reach 6000cd/m,protection standard can reach IP65,it can fully adapts to all kinds of bad climates and realize remote controlling ,it's your best choice for long term outdoor used.

What is the difference between traditional luminous character(short for tlc below) and led display luminous character(short for ldlc below) ? normal luminous character consists of metal board 、led light source and shells ,it can shines single or colorful light and used as signages for enterprises or stores;for ldlc,it makes a character shape in the screen ,actually this is a heteromorphism led display screen ,it can be used as logo signages,as well as playing videos,the huge advertising effect is abviously .

Those two type products are the main products in the market,below is the advantage of led display luminous character,comparing to traditional luminous character :

1)Strcture,tlc's structure is simple;the ldlc has the same structure as display screen,display module design,no limit in screen size,flexible showing all kinds of characters、pictures and logos;

2)Luminous effect,tlc shines relatively warmer light, with low brightness and single color,ldlc has higher brightness,excellent color effect ,saving energy and eco-friendly;

3)Feeling,tlc is static ,cannot be moved;ldlc can play many different videos ,also can play special videos when needed;

4)Economic benefits,tlc can only shows the company name or store logo;ldlc can not only shows the company logo,but also publish advertisements,it has strong economic benefits;

5)Application field ,majority tlc were applied in some small hotels、restaurants、supermarkets and so on places;ldlc mainly applied in tall buildings、well-known companies、bank securities、municipal constructions and landmark buildings etc;

Having above many advantages,we can predict that ldlc is the developing trend for outdoor signages.We believe in future,ldlc will play an important role in energy saving and eco-friendly market,lighting up our colorful life.

Highlights in 2015 GILE?

2015 GILE,also known as “Guang Ya Exhibition” successfully finished,as a participant and professional LED module manufacturer,Yayuhong Optoelectronic & Technology has made a conclusion about it as below :

First,Foreign encapsulation & chip suppliers begin marketed csp

Second,Many domestic and overseas component product manufacturers are focused on LED lighting source modules,especially ic integrated products;

Third :EMC component products made high power high bay light and flood light,copying integrated encapsulation technology;

Fourth,For ic integrated lighting source module divided into low power components and single COB components,they are used in different places.

Fifth,Automobile lamps,all lamps becomes modular,especially for headlight and turn light;

Sixth,Intelligent lamps lighting scheme, intelligent solutions for family and business places  

Seventh,Direct type back lighting source,all TV signage products already contains csp products;

Eighth,csp encapsulation is copying COB , cascade and parallel connection for many small components,it can be encapsulated infinitely;

Nineth,COB components which under 30w is still the mainstream products in the market;

Tenth,50w above Integrated encapsulation products has the advantage in cost performance;

Eleventh,Application of UV light is becoming more and more polupar ,also the popularizing rate becomes higher and higher;

Twelfth,Plant lighting aspect,mainly made up of blue and red light;

Who is the best LED module supplier in china ?

Yayuhong Optoelectronic & Technology (short for "YYH" below)specialized in design ,produce LED AD lighting source product,main products include LED AD lighting source module、LED injection module.

We provide LED module price,wholesale price,we will be appreciate to receive your call,YYH devote ourselves to be the best LED module supplier in the world.

YYH-----A Rising Star of AD Lighting Source Module Industry

Light source, as the lighting component of led modules and led strips, as well as the core component, it plays an important role in the quality of whole module. we mainly choose below core components: Cree,Osram, HP, Epistar, production process according to client’s requirement and provide inspection report. for the top shells, we use ABS+PC combo, double color injection machine process,the combined parts of ABC and PC was injected by high temperature ,waterproof level can reach IP67 or above. For bottom shell, we use ABS + high temperature resistance metal powder mixture. For the welding oftop and bottom shells, we use ultrasonic welding technology, the waterproof level can reach to IP67, verified certificates provided .We use international standard No.18 tinned wire which the cable quantity is 41,all modules use constant current ,that makes the light and modules works more steady .also we can print the logo as client’s required, adding our strict quality control system , we promise a 5--year warranty .

Maybe you are using Korea module since no trust on products from china. Actually module itself is a very simple product with no complicated circuit and many heat dissipation processes(because it’s not a high power product),you can see everything when split. For korea brand modules, they didn’t use aluminum base at all. Maybe you used to import led modules fromother china suppliers and caused many quality problems ,more importantly theydon’t have a right attitude on it. New products brought passions to those suppliers,they don’t even catch the essence of module, they earn high profitbut don’t use better material ,adding lack of production experience, as well as low factory threshold(several workers can open a factory). All these factors makesa bad module market in china before.

Along with more and more complaints from customers ,those china manufacturers began to realize their deficiency and stopped aimless production and develop their own new products, they’ve gotrapid progress no matter in appearance and performance,so currently the products which from the top china suppliers is not bad . we’ve been in industryfor years and know the situation of china module market very well, 2 korea brand module manufacturers are using our lighting source for years. About china module manufacturers, YYH CTO specially published a editorial named <China Module manufacturer >,he made a accurate analysis on china module suppliers, hope you can have a notice when available. We can take you to every china module manufacturer that you want. We are confident of ourselves, no matter in capacity, product appearance and quality. many buyersmay think we are bragging, we suggest you buy a small amount to do the test ,wewelcome query and we will defeat query by our product. our products are able toon a par with GE led Module/SS LED/NC LED/GOQ LED and so on brand products.

A new type led lighting module successfully developed

Yayuhong Optoelectronic& Technology developed a new kind of AD lighting module,which is differentfrom traditional dripping module and LED injection module. Shiningappearance,reasonable structure ,with excellent material,those makes anunparalleled products in both beautifulness and reliability .

We named “SmallLighting Source Module Carrier”(short for “SmallModule Carrier”below)for this new module,it can not only carry any type CreeSMD light sources,but also can emit any Osram square type LED lightsources(lighting level ), besides,we can also carry Samsung and LG lightsource.Generally we use Cree and Osram light source,we have many yearspartnership with them.

We have an internal name forthis kind of module,it’s YYH-15DXXX-M3X-XXX,with 63mm length,15mm width and 8.5mmheight,pure white top shell and bottom shell.use ABS ＋PCmixture,the suitable proportion makes the module rather firm.the Emitting colordivide into red,yellow,blue,green,white(warm white,pure white and coolwhite),the single power between 0.2w-3w ,total power is between 0.6w-9w,currently no single 3w 3 led module and 9w power module in china market),it canmeet different AD signage product needs ,lumen between 70-950 lm ，the driving voltage is between 12v-110v(traditional driving voltage is12v,this is

notan scientific combination between power supply using and module connection.Highvoltage and low current is a trend in the coming future.

For the procedure andstructure,our method is to weld top and bottom shell,this can make real IP68,sono need to worry about the waterproof function when using.besides,ABS itselfhas flame-retardant function,adding fire retardant on the shell.compare totraditional module,we have unparallel advantage in both waterproof andfireproof.

We fully use UL certifiednational standard cable,currently the copper core number is 41,different specmodule quantity of a series is between 50-2000 pcs,based on different drivingvoltage and light source voltage (it’s convenient and saving wheninstallation,and will not exist brightness difference anymore )

To fix the module,werecommend using screw ,sure it’s ok to use 3M glue when low power,the normaloperation temperature is between -40°and 85°。Forexample,if export to Russia,the key parts we use is conform to militarystandard which will not effect it’s function due to low temperature,we promise50000 hours above lifespan(unless problem from your power supply).

Overall,besides the featurefrom traditional module,you can see it’s specialty from any technology aspects,it can make excellent lighting effect in different back lightdistance,different emitting position,different working environment

The“Small Module Carrier”will set sail to the world in 15^th.June , believe it can ploughthrough everywhere in the world.We sincerely invite those excellent agency fromall over the world join us

Current module structure in china market

Along with economic growth and development of AD industry,plenty AD signage products comes out,meanwhile it brings flourishing market for LED lighting source industry, thousands of AD light source products chocking up the goods shelf and lighting up any products sings.AD signages,indicators,lighting boxes,signages,Static and Dynamic display,AD machines etc.application areas from individual household to commercial bank;Fromlandmark indicator to controlling center display;From doorplate display,channeldisplay,jewelry display to construction profile ,airport,railway station,supermarket and so on different places.
There are nothing else than 2 structure modules:
First one uses dripping technology,materials includes:PVC module shell,PC board,lamp beads,cable,glue,resistance,solder paste.Stick the beads and resistance on PCB,using chip mounter;Then bonding wire and connect the cable on two PCB ends,put PCB on the PVC bottom shell,dripping epoxy resin,last step spontaneous curing.
The second one is so-called “injection module”.Sames as dripping module,difference is that it sends a PCB(with cable and beads)into injection molding machine,then wrap with PVC or ABS.
For the dripping module,the module seems fully wrapped the PCB,in fact it will result gap between epoxy resin and other arts,because of below reasons:quality of epoxy resin,operation time,environment of the material which contacted by epoxy resin,will work longer time if good waterproof function.If working under high moisture ,high temperature or raining place for long time,maybe the lifespan of the module will not exceed 3months,so structure is important;Besides,another reason is that it’s incompatible between epoxy resin and beads used silicone ，if any redundant contact when production,it will result vulcanized in the coming future so that the module cannot work regularly.In all this kind structure module ,will stop working because of structure probloem when high temperature,high moisture or a vulcanized place .
Comparing to dripping module,injection module will be easier in production controlling and it can change the viewing angle by lens ,in order to apply to different AD products.They have the same short comings with dripping modules,if any QC problem,the waterproof function will begreatly reduced,adding complicated production procedure ，low production efficiency,it rather difficult to be a eligible controller,even if comes good products,the price will be extremely expensive.
So in china,if any customer complaints happens,it will end up with nothing definites,since it’s decided by material,technology and production efficiency etc.Every supplier sold their products with margin.So among those china module manuacturers,the product wasnot so quality,because of their management level ,different kind of materialetc….

PCB standard of LED module

General printing board used baseplate material can be divided into 2 types: Rigidity baseplate and flexibility baseplate. an important type rigidity baseplate is CCL, it uses reinforeing material with resin adhesive, via drying, cutting, mounted into blank, then covered with copper foil, using steel plate as molding, coming into formed by high temperature and high pressure in 
hot press. the general composite board used prepreg, is the semi-finished  CCL when processing(mainly glass cloth soaked with resin, with drying process).

PCB standard of LED module

There are many sorting methods forCCP(copper clad plate).generally if according to different reinforcingmaterial, can divided into: paper base, fiberglass fabric base, combined base（CEM series）,laminated,multilayer base and special material base(ceramic, metal….) and so on 5categories. If according to different type plate used resin adhesive, usualpaper base CCI include:Phenol-formaldehyde resin(XPc、XxxPC、FR一1、FR一2etc)、Epoxy resin(FE一3) 、Polyesterresin and so on types. Usual fiberglass fabric base CCL is Epoxy resin(FR一4、FR一5),this is the most common .Besides ,Thereare other special resin(use fiberglass fabric ,poly amide fiber, nonwovens asstrengthen material):BT, PI, PPO, MS, poly cyanic acid resin, polyolefin resinetc.

If according to flame retardation, it can be divided into antiflaming (UL94一VO、UL94一V1 level ) and unantiflaming (UL94一HB level).In current 2 years, with the eco-friendly becoming more and more important, there is a new CCL type which doesn’t include bromine, it can be called”green flame retardation CCL” with the highly speed development of electronics ,the requirement for CCL becomes higher. So, according to the performance of CCL, it can be divided into General performance CCL, low-k CCL, high thermostability CCL(normal ones is higher than 150℃),low CTE CCL(generally used on package substrate )etc.

The highly developing electronic market raise new demands for PCB base, this push the development of copper-clad plate standard. Currently, below are the main standard for baseplate material:

1)      National standard. Right now in china, relevant standard include GB／T4721—4722 1992 and GB 4723—4725—1992,for Taiwan is CNS standard which drawn up to JIS Japan, publish in 1983.

2)      Standards in some other countries:

JIS(Japan); 

ASTM,NEMA, MIL, Ipc, ANSI,UL(US);

BS(UK);

DIN,VDE(Germany);

NFC,UTE(France);

CSA(Canada);

AS(Australia);

FOCT(FSU);

IEC(International standard).

Some standard name and department that set the standard:

JIS-Japan Industrial Standards- Japan Standards Association
ASTM -American Society fof Testi’ng and Materials 
NEMA- -Nafiomll Electrical Manufactures A~ociation- 
MH- -Department of Defense Military Specific tions and Standards 
IPC- -The Institrue for Interoonnecting and packing EIectronics Circuits

Current Situation of World AD Lighting Source Module Market

LED module,as anew light source in the lighting industry,is widely used in AD industry alongwith the economic growth and ，mainly because it’seconomy,durability,safety and easy maintainace .The fact shows that it willreplace AD light source neon light,fluorescent light in all dimension

Market drivesproduct innovating,Product promotes market developing,this is the nature orderof the market

GE led firstdeveloped a new kind module,and widely used in first class US AD case becauseof it’s brand value,after 2 years,some EU first class AD brand began to use GEled module。GE took the first step to success, GE usedto sell 1pc 3led module at $10 more,this is the highest price for single moduleever .Because of margin ,thousands of companies started copying GE moduleproducts.since too high brand-added value,GE module can’t accepted by majoritycustomers and hard to arrange mass production.Even so,GE play an certain roleto promote the AD industry

Besides GE,thereare some South Korea brand: NCLED、GOQLED/SSLED/OKLED/ANXLED，let’s start from NC,they firstly copied thestructure of GE,but use LG/Samsung chip instead.Their module were sold all overthe world . NC staff they don’t know the concept why GE developed this kind ofproducts,currently they don’t even know the characteristics of the material,becauseprofit is their only pursue.they earned $5million net profit each year in lasttwo years.

Next one is GOQled,I fully believe they are copying NC led and the market is not bad incurrent two years,for SS led,they already got by NC and GOQ,they only have 2new kind products in last two years,I think they are retrogressing,they justsell a different product which is no use for market growth.OK led and ANX ledare two industry rookies,no exciting product .what’s more,majoritymanufacturers who are with LG and Samsung brand,they import millions of LEDchips from Taiwan china every year

Here I would liketo analysis the module market in china,currently famous brand includeBlueview,Jingge,Chuangtong,Rishang,Mynice(used called LEDEL) .After severalyears competition,Rishang becomes the leader among them,partly because shedeveloped foreign market earlier and catch the best chance which market starteddeveloping.another reason is they used to have sales with good negotiationskills ,like GE,they also used to sell single module at a crazy price , I haveto repeat they just catching the right time.Along with the customers more andmore knowledgeable in products and more suppliers being appeared,they have noadvantages at all,that’s why they were acquired by Mason（China listed light source company），no need mentioning capital operation here.ForBlueview,their decision maker used been abroad and join module industry by achance,after all,it’s a miracle that they can run a not bad business without abig market and professional leader.

Chuang tong usedto have a chance to lead the industry,but they choose a wrong light sourcemanufacturer ,two years later their module business dropped into rock bottombecause of quality,from that time,they dropped out of the market gradually,turningmaking power supplies,no new for them for ages,someone says they are doingcapital operation now.

Last modulesupplier is LEDEL company which leader has been changed for several times ,whythey enjoyed certain reputaion in the market is their current decision maker,heused to be sales GM in Rishang ,also is he who helps Rishang to sell a singlemodule at a crazy high price，what I need to respect them is their salesmethods and ability,but not product.

In all,AD lightsource industry created many richmen in ast few years.
