LED light source developing trend and current situation


LED was used as lighting products in recent years,the most simple and direct applications is to replace bulb and fluorescent lamp.This can be accepted more easily.Besides,there are no abvious change on appearance and effect .Surely,with more and more personalized for lighting products today,lamps itself already becomes the quality index of light,however,the led module has so many advantages ,also come with some factors which customers doesn't find,like glare and costs.For the lighting structure which people familiar with,LED is different from traditional lamps in nature(like directivity).
if still coordinate with traditional lamp structures,their own specialty will be overwhelming.Now,there are led down lights and led bulb lights in the market,for the former,it needs to put light sources,the latter itself belongs to a light source.the question that we need think obout is :when installate a led bulb lights in traditional down light,can the light source which installted in led bulb lights be installated in downlight structure,the answer is clear yes.whatsmore,the cost effect also be more favorable than bulb lights.
but the question is ,when a non-standard lighting source structure putting into market,the customers cannot be replaced easily.So a difficult question for light source manufacturer is :what is the standard lighting source structure.encapsulation companies needs to be modular and standardization for light source,only that the cost can be optimize.

LED module using instruction

1.The light source of luminous characters used at present is mainly general settings input voltage which is DC12V, these kind of 3 or 4
 is very common, they need through  constant voltage switching power supply to input DC12V as power supply, for that reason it must be careful when install luminous characters, if it did not install switching power supply, do not let the luminous characters or LED light source modules access to the mains ac 110 v directly, otherwise the LED light source will broken down for the high voltage.
2. In order to avoid switching power supply's long-term full load working, the best load power for switching power supply and LED is 1:0.8, according to this setting, the product's life span will be longer.
3.If the modules series are more than 25 pcs, those modules should be connected seperatedly, then they should be parallelledly connected by high quality copper wire whose diameter is 1.5 milimeters to the light box, power line should be as shorter as possible, if  the length is over 3 meters, the diameter of the copper wire should be widen.
4.Enough luminosity is required.visible luminosity of module spacing is required between 3 and 6cm, the thickness of word can be between 5 and 15cm. two kinds of LED lighting sources can use luminous words:piranhas and small straw hat.the piranhas luminous module is applied to the luminous words  for which the height of the word wall between 8 to 15 cm
5. In the process of using LED luminous module, attention should be paid to voltage drop. Be care not to make only one loop to connect in series, which not only cause different brightness between the head and the tail due to different voltage, but also leads to circuit board overburning because of over-loaded single circuit. The correct way is to connect shunt circuit as much as possible to ensure rational allocation of voltage and electric current.
6.If antiseptic material needs to be used in internal space ,white primer will be better ,can increase its Reflective coefficient.

Packaged LED providers diversify into module market

Led Modules
 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.

Four key points in led AD light box structure design

AD light box structure should be based on the city culture、custom and characteristics in order to design a light box more suitable to the local culture and landscape .below four key points should be noted when design the light box structure:

First,ventilation and heat dissipation process of the tube should be noted.There are tube and digital scrolling systems in the light box,so try to make some more vents to keep the good heat dissipation ,in condition not effect the product appearance;

Second,waterproof process should be noted;

Third,The design should be conformed to the city culture.Even in one city,the light box structure may not be identical.When designing,the structure should be conformed to the lanscape around ,so that the light box can be more practical ;

Fourth,The tube quantities is based on the light box size,the light box thickness should be considered when align the tube,the tube should keep a certain distance to the baseboard of the light box.


Yayuhong Optoelectronic& Technology developed a latest AD light source module ,to increase the heat dissipation performance,we use ABS+PC+metal powder shells,meanwhile,waterproof level can reach IP67.It can be not only used in light box,but also widely used in all kinds of logo、signage lighting projects as well,besides high brightness and good heat dissipation performance,we provide an average 5-year lifespan.

It will be proved to be the best choice for your light box,AD signage and lighting projects.

How to design a good signage

As industry leader,YYH think that signage design and installation ,must be conformed to novelty、markedness、simple ,not only artistic ,but also can attract customer's attention.Because the signage itself is an advertisement with a special meaning,in a common sense,a good signage design can be seen clearly from a long distance and many angles from customers,it should be go with LED lighting source modules during night time.In general,below information should be considered when design and insallate the signages:

Signage shape、spec and installation method ,try to be multiple and different.It needs to be not only attractive,but also matching your style,those makes a perfect appearance ;

There are many materials for signages:woodiness、stone、metal,also it can be embeded in decration wall surface directly ;

Installation can be vertical type、wall type,also it can be suspension type ;

For many medium and small professional stores,the product and business can be seen directly from their signage .if the signages match the product and business the yare running,that maybe strengthen their calling;

For example,there are many different types of signage for different business scope of clothing shop.A dress shop can choose a signage with strong fashion and the color should be markedness;A man's wear shop needs to be solemn,since it's main business is western-style clothes which belongs to official ones.Children clothes shop signage needs to be active and funny,since it can attract ther attention .  

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.

Which is the most profitable business--Luminous character

Luminous character

Which is the most profitable business?advertisement design is your best choice,many new stores opened everyday in every city,many annunciates and notifications needs to be published .New stores needs their AD signages,and none of them wants a same signages with other's,they want a more beautiful,more attractive signages,so they always spend more money on that.

For led AD modules,which kind effect is more active and attractive when publishing a notification or a annunciate ?channel letters is your best choice,our designed led lighting source module can reach IP67 on waterproof level,that's the level which the low price dripping module can't reached .just need to assembly the finished materials,a perfect and satisfied products was made , but how to attract customer ? price is the first attraction and biggest advantage ,second our lighting effect should be better ,clean but not dazzling,with an acceptable price,your product will be hot sales.

In general,Luminous character is the most profit business now.

The best carrier for outdoor commercial AD signages

History for led technology is not long,the first red light led been produced in 1969 ,in 1970s,the low luminous effect led started to be used in indicator、numerical and character display.since 1990s,full color led display developed into a new star in global display media market ,it uses led made lattice module or pixel unit made big size display screen,adding high-tech like microelectronics、optoelectronics、information processing etc,it becomes the best carrier
for outdoor commercial AD signages.
LED AD module is kind of product which arrays the LED in a certain rules then packing ,adding some waterproof treatment .mainly used to display AD character(AD board,outdoor AD) and night signage effect ,it uses character or signages as media,installed at top of the building or wall surface.It can not only show the daytime effect ,but also showing another effect during night ,using led as lighting source .
LED panel is a kind of display screen which shows characters and videos by controlling semi-conductor led .mainly including graphic display screen and full color display screen with LED lighting application controlling system,doing a dynamic video control to the character and signages.In some entertainment places,LED lighting source module becomes the best way to show their images.

Production knack of punching module


Punching led module channel letter is a common AD character in our daily life,because of high hurricane resistant,high brightness,easy protection,it is a very popular products,so how does punching led module channel letters be made ? here i'd like to introduce the production knack.
First.Prepare the production tools :30w or 40w electric soldering iron、soldering tin、electric drill、glue gun、screw driver and so on;
Second.Prepare the material :Formed tin word、glass glue、resistor、cable、led module special used power supply;
Then start production ,detail procedure as below :
1) Drilling hole:Fixed the out sourcing tin word in a suitable direction ,drilling hole with electric drillings:5mm or 8mm,it depends on the height and production cost,usually the module center distance is 10-30mm,the shorter the distance,the better product and the higher cost;
2) Insert the lamp:Clean the well drilled hole and then arrange;
3) Connect the wire :First cascade, then in parallel with the power supply,the procedure maybe difficult,but no worry,
AD compaines already have ready-made led module string light which can be connected to wire,every light has it's reserved thread residue.Usually red ones connect to positive pole of the power supply,black ones connected to negative pole.

How about the performance of LED AD modules ?

LED AD modules can greatly dissipate the heat ,reduce the light dacay;aluminum board can bear the higher voltage,effectively reduce the power drop,ensure the brightness consistency of every module in the signages,to improve the product quality.


For the chip,we use big size,low light decay types;low power consumption、high brightness、five-year lifespan,free maintenance;using aluminum shells,not only beautiful but also with good heat-dissipation,reduce the light decay;using DC12V power supply,safe and reliable;aluminum board can prevent the fire and retard the flame; lamp beads with heat sinking ,effetively reduce the inner node temperature ;According to color,LED AD modules can be divided into single color ,RGB color and full color.The single color module means the module which only shines one color,like red、green、yellow、white etc ;RGB color module is one that can change the color between seven colors .Variability and more color are the biggest advantage;Comparing to RGB,full colr module is better ,it can realize the real color changes,not only amazing ,but also dynamic ,also more attractive.

Classification of LED AD module


According to color,LED AD modules can be divided into single color ,RGB color and full color.The single color module means the module which only shines one color,like red、green、yellow、white etc ;RGB color module is one that can change the color between seven colors .Variability and more color are the biggest advantage;Comparing to RGB,full colr module is better ,it can realize the real color changes,not only amazing ,but also dynamic ,also more attractive.
According to the power,it can be divided into low power( below o.3w )、medium power (0.3-0.5W)、high power (1W and above),comparing to low power module,high power ones has a higher brightness and longer lifespan,also more practical,it's the developing trend of led lighting in the future.
According to leakproofness,it can be divided into waterproof module and non-waterproof module .the main difference between waterproof and non-waterproof is in operation environment .usually waterproof ones can be used in ourdoor lighting and signages,no need to worry that it will be broke because of inflowing ,it's more suitable to use in worse environment,non-waterproof ones mainly used in indoor environment.Sure,the price of former is higher.
