Requirements during using outdoor LED module

LED module is to array the luminous diode according to certain rules,then encapsulation,adding  waterproof process,that is called LED module.The application of LED module is extensive,so do you know any attention needs to be noted during using LED module (for LED module classification,click <<Classification of LED module >> ).

First,the normal LED module use 3 LEDs,5 LEDs,6 LEDs ,they need to output by constant switching power supply,so be note whether open the switching power supply when installate the channel letters,be sure not connect outdoor LED modules to 220V voltage directly,or it will be burnt.

Second,To avoid switching power supply long time overload working,the best load power of switching power supply and LED module is 1:0.8,by this ratio,the operating time of outdoor LED module will be longer.

Third,if exceed 25 series ,it should be connected separately, then parallel them with high quality copper wire,power line should not be too long , remember to cut redundant wire in module end and stick firmly,avoid short out.

Above editor conclude several requirements needs to be noted when using outdoor LED module,please use it properly.

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.

Lextar to Showcase Frameless LED Panel Light at HK International Lighting Fair

Lextar Electronics Corp, the LED vertical integration manufacturer, will release its new generation LED flat panel lights – ALLUXIA. ALLUXIA’s frameless visual effect can create flexibility for seamless connection of luminaires. With its simple and neat appearance, it opened a new era of LED flat panel light 5.0.  Lextar will unveil ALLUXIA at the Hong Kong International Lighting Fair taking place during October 27-30, 2015.

Lextar is to release new LED panel light that create soft glow to the space. (Lextar/LEDinside)

Since Lextar released its first LED flat panel light in 2010, it has continually been improved and evolved, and has now reached its fifth generation. Lextar’s newly released ALLUXIA flat panel light adopted its mature backlight technology to further improve the planar optical performance, and created a frameless, full-surface luminous visual design. The surface mount installation can create continuous illuminating visual effects, increasing the flexibility and fun of indoor designs. Its frameless outline and thin, low-key appearance allows it to elegantly blend in with the environment, satisfying the diverse needs for various interior designs. As for its product specifications, the ALLUXIA flat panel light uses the microstructure optical technology of a special light guide plate to create balanced and soft surface light, and is able to reduce glare. The innovative aluminum frame structure allows the luminaire to have both the advantages of being lightweight and also being strong to avoid bending when suspension. In addition, the thin design not only allows it to suspend or surface mount onto the ceiling, creating the effect of making the ceiling look higher and releasing space height, it can also reduce packaging materials and lower transportation volume significantly, therefore meeting environmental protection demand.

The Associate Vice President of Lextar’s Lighting Business Unit Mr. Francis Wong stated that Lextar’s years of leading development and market operations for LED flat panel lights have won great reviews in the European and American markets. Since the release of Lextar’s first flat panel light in 2010, it has been through the second generation plastic frame panel light, third generation ultra-thin LEAFIA panel light and the fourth generation Driver Inside all-in-one integrated panel light. The evolution of the technology and demand in the panel light market could be seen from Lextar’s product development track, and this has also become the key why major brands continue to cooperate with Lextar to develop panel lights products. This time, Lextar continued to use its optical, mechanical, electrical and thermal integration technologies and innovative designs by the industrial design team to release the ALLUXIA frameless flat panel light, which will be making its debut on October 27 at Asia’s most important lighting show – the Hong Kong International Lighting Fair (Autumn Edition). Lextar will be displaying its LED product lineup including flat panel lights and liner lights, ultra-high color rendering (CRI 97) tubes and smart tubes for parking lot, and LED module series at the Hong Kong International Lighting Fair (Autumn Edition). This is the seventh showcase Lextar demonstrates the LED lighting products at this fair; please visit more exhibit details at Lextar event site: http://www.ledmodules.net/news/Industry/led-lighting-module.html.

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;

Thirteenth ,Blue diamond bottoming filament is still the main products which replaces the tungsten lamps,

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.

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.
