How to use LED Injection Modules properly

LED Injection Modules was used to display AD letters and night signages,not only take advantage in night time,but also in daytime.When night falls,LED lighting module brings it’s gorgeous lights,that makes visible for customers from distance  ( out door LED module operating requirements,click << Key knowledge point of LED module

>>).

So how to use led sign module properly ?that’s also the way to ensure security and operating time .Currently used channel letter light source,usually input the voltage by regular settings ,normal types are DC12V 3LED,5LED,6LED,,needs putting out by constant voltage power driver.So pay attention to open and close the driver when installation,remember not connect 220V AC,or LED will be burnt.

Second is to use it properly ,don’t work overload ,load power ratio of switching power supply shoud be 1:0.8.If exceed 25 series ,it should be separated and connect,then parallel them with copper wire which is bigger than 1.5 SQMM.

Third,visibility between modules should be around 5m,to ensure the enough brightness.

Fourth,pay attention to voltage decreasing problem,try paralleling some return circuit,distribute voltage and current properly,avoid inconformity of brightness and burn the PCB because of too big single current.

Key knowledge point of LED module

LED module voltage is from 2-4 volts ,power also has wide range,,which kind of LED to choose mainly depends on the detailed technical requirements.For example,if need output 10lm light,from the appearance,it’s better to choose 2 LEDS with 5lm each ,considering color(LED voltage is related to color)、temperature、quality and other factors,you will find an appropriate LED product

Choosing imported high quality ultra high brightness LED chips、full-auto encapsulation facilities、professional light source for outdoor and indoor letters、signages、signboard and AD light box .unique high brightness、long lifespan、eco-friendly、gorgeous colors、strong environment adaption、safe 、convenient、reusable and so on ,can fully replace neon light and other traditional light source,help AD companies better meet client’s demands ,at the same time,they can get maximum economic benefit.

Main features :

1)Save electricity:low process cost,save 80% and above electricity than traditional light source,really save money for users ( outdoor LED module development,click <<Three advantages for LED advertising module>> );

2)Long lifespan:Under normal circumstances，it can be used for 15-20 years in condition 12 hrs a day,not easily damaged,ultra low maintenance fee,3 years warranty;

3)High brightness、gorgeous colors:electric energy can transformed to luminous energy directly,axial brightness is more than 10 times than traditional light source,it is solid cool light source,able to supply 460-630mm full color and white color super  bright products;

Silent LED Message Center Killers: Heat

Heat kills LEDs. The death knell of a typical Red-Green-Blue (RGB) full color LED display is seen in depreciated light quality, poor color quality and eventually a dim, dying sign. Typical lights dissipate heat by radiating the heat outward from the source. LEDs unfortunately hold the heat in and high temperature slowly breaks down the components causing a multitude of problems. Red LEDs burn out faster and this is usually seen on a message center when  “clean white” turns to a bluish hue because of the lack of strong Red LED components.

Thermal (heat) management is critical to the longevity and continued high-level of performance for a message center. Manufacturers tend to deal with thermal management in a variety of ways:

• Heat sinks (metal spread out and “finned” to allow for heat to draw away from the LED and let passive/active airflow over the fins dissipate heat buildup
• MCPCB (Metal Core Printed Circuit Board) – a rare option due to increased expense
• Separation – a popular method, LEDs are separated from the circuit board using longer “legs” which allows for air flow to draw heat from the LED through the extended legs, unfortunately proper placement/setting of LEDs is difficult and can result in bad contacts which leave “dead pixels” on a sign.

All the above methods serve to draw heat away from the LED source thus keeping the LED relatively cool and ensuring the highest performance and longest life possible. With this in mind, here are LED killers to watch for on an LED module (also known as a driver/board):

1.    ANY type of heavy/dark silicone coating on the back of an LED PCB (Printed Circuit Board: Silicone coatings have the benefit of reducing exposure to condensation which can oxidize metals, but it’s better to use a light conformal PCB coating. Heavy silicone coatings trap heat and don’t leave any place for the heat to be drawn away. Be wary of modules with “heat sinks” as the heat sinks often don’t have trace leads (metal pathways from the LED to the heat sink) and thus do not work to reduce heat on the overall module.

2.    LEDs which have no louvered (shaded) protection: the louvers on a face plate for an LED module act like an umbrella at the beach. They serve a dual purpose of allowing LEDs to shine their brightest in daylight conditions while also giving them some protection from direct overhead sun  exposure. If you see a face plate with exposed silicone, be especially wary. The silicone acts as a sealant to protect the LED Injection Modules face from weather elements, but an exposed silicone coating is prone to UV (Ultra Violet) solar radiation which will crack the sealant and cause eventual exposure to the elements which will kill the module over time.

3.    led sign modules which are “fully enclosed” from the rear: Picture a medieval knight in full armor standing in the summer sun, that knight is likely more than a little warm. While the rear seal plating looks great on an led sign module and it sounds good to have a “waterproof” LED module, the plating doesn’t ultimately protect the LED, it harms the LEDs in a module because heat has no source to vent off to. If the manufacturer is using a rear-face module, have them show you a cutaway or internal view to see how they’re drawing heat to the back plate. If they aren’t drawing heat from the LEDs to the back plate, they’re slowly killing your sign.
