How to verify high quality LED module lights?

What is LED sign modules?

LED sign modules are a type of LED light source specifically used for advertising signs, light boxes, and other lighting applications. They are usually composed of LED chips, PCB boards, lenses, packaging materials, and connecting wires, and are designed with long-term stability and brightness uniformity in mind.

Features of LED Modules for Signs

1. High brightness and high efficiency

LED modules for channel letters usually have high brightness and high light efficiency (e.g. 200 lm/W), ensuring that the logo is clearly visible during the day and at night.

2. Lens design

The lens in LED module sign lights can optimize the distribution of light, make the light more uniform, reduce light spots or shadows, and enhance the visual effect of the logo. Some constant current LED modules are designed with 180° wide-angle lenses to cover a wider area.

3. Protection level

High-quality LED lights module usually have a high waterproof and dustproof level of up to IP67 and IP68. The protection design can also ensure that waterproof LED module is resistant to high temperatures, UV, and vibration, extending the life of SMD LED module.

4. Constant current driven

The constant current LED modules design can ensure the stability of the current of each LED, avoiding inconsistent brightness or light decay problems caused by current fluctuations. This design can also reduce heat, thereby protecting the LED chip and extending the service life of the LED modules for signs.

5. Material and packaging

The use of durable packaging materials, such as flame-retardant plastics or silicone, can enhance the durability and safety of LED string light modules.

Application of LED Sign Modules

LED sign module lights can provide strong and uniform light sources. There are many advantages to using LED lights module have become the preferred solution in modern sign and lighting applications.
Advertising signs: LED module lights are often used for LED channel letters, backlit signs, etc.
Light box lighting: LED signage modules are used for indoor and outdoor single-sided and double-sided light boxes
Store signs: LED light modules are widely used in store sign lighting
Architectural decoration: Storefront LED module light can also be used for architectural outline lighting, bridge decoration, etc.

How do you choose premium LED module ?

To determine the quality of high quality LED sign modules, you need to consider its performance, materials, design, and manufacturer reputation. Here are some key indicators that can help you judge the quality of LED signage module.

1. LED chip

Brand: Premium LED sign modules usually use well-known brands of LED lamp beads, such as Osram, Samsung, Philips, Lumileds, etc. These LEDs excel in brightness, life, and stability.
Luminous efficiency: Best quality LED modules have a higher luminous efficiency, usually 150Lm/w or 200 lm/W or higher, which can provide a brighter light source while reducing energy consumption.

2. Optical performance

ADLED LED modules lights are usually equipped with high-quality lenses to optimize the distribution of light. High-quality modules will have good brightness uniformity, without obvious spots or shadows, which is crucial for the visual effects of signs and light boxes.

3. Materials and packaging

High-quality modules usually use thick copper PCB boards (such as 2 ounces of copper) to ensure better heat dissipation. High-quality modules use high-quality flame-retardant plastics or silicones, which have good weather resistance, high temperature resistance, and UV resistance. Packaging processes such as ultrasonic packaging technology can ensure the sealing and waterproof performance of the module to prevent moisture or dust from entering.

4. Color temperature and color rendering index (CRI)

Durable LED modules have good color temperature consistency. ADLED's LED module lights use the same BIN number to ensure that the color temperature between different batches of LED modules for signage lighting is highly consistent. Best LED modules usually have a high color rendering index (CRI > 80), which can more accurately restore the true color of objects.

5. Service life

Long life LED lights modules usually indicate their service life (usually more than 50,000 hours) and provide a long warranty period, which shows that LED sign module suppliers is confident in the quality of the product. ADLED provides a 5-year warranty for all LED module lights.

6. Certification

LED module 12v will pass a series of international certifications, such as UL, CE, RoHS, etc. These certifications indicate that the product meets international standards in terms of safety, environmental protection and quality.

7. Reliable LED module factory

Choose a branded LED module supplier with many years of experience and a good reputation. Usually these LED modules for signage suppliers pay more attention to product quality and customer satisfaction. These LED module light manufacturers generally choose to participate in some local sign exhibitions or are very familiar with the local market.

Instructions for Use of LED Sign Modules

At present, LED modules for singage are mainly LED 1, 2, 3 and 4 light source modules with conventional input voltage of DC12V. They need to be powered by DC12V output by a constant voltage switching power supply. Therefore, if LED power supply is not installed when installing LED letters, do not connect illuminated letters or LED sign modules directly to the AC 220V mains, otherwise the LED signage modules will burn out due to excessive voltage. Of course, our company can also provide DC 24V LED module, AC LED module, etc.

To avoid LED driver working at full load for a long time, the best ratio of LED drivers to the LED load power is 1:0.8. If LED modules for lightbox is configured in this way, its service life will be safer and longer.

If there are more than one string, they should be connected separately first, and then connected in parallel to the outside of lightboxes by high-quality copper core wires larger than 1.5 square millimeters. The length of the power cord should be as short as possible. If it exceeds 3 meters, the wire diameter must be appropriately increased. The unused wires at the end of LED light modules for signage must be cut and pasted firmly to avoid short circuits. If necessary, they should be fixed with self-tapping screws. When the non-waterproof series is used outdoors, the grooved characters must be waterproofed;

There must be enough brightness. Best LED modules for signage of different powers are suitable for advertising signs and light boxes of different sizes. Please choose the right LED light module for signs to ensure that your luminous signs are evenly lit, without dark spots and with sufficient brightness.

In the process of using LED signage lighting modules, you must pay attention to the problem of voltage drop. Never make only one loop and connect the end in series from the beginning. Doing so will not only cause inconsistent brightness between the beginning and the end due to different voltages, but also cause the problem of excessive single-channel current burning the circuit board. The correct approach is to connect as many loops in parallel as possible to ensure a reasonable distribution of voltage and current.

If anti-corrosion materials are required inside LED letters, it is best to use white primer to increase its reflective coefficient.

The adhesive backing of the LED module usually only plays a temporary role in stabilization. If you want to install LED module for sign board for a long time, please use professional glue or use the screw holes to firmly fix LED sign lighting modules on the aluminum substrate or other backplane.
