FAQs You Need Know about LED COB lights

COB stands for "Chip-on-Board" and is a type of LED that consists of an array of LED chips mounted on a substrate such as silicon carbide. It is compact, energy efficient and excellent brightness uniformity, making it popular with photographers and filmmakers. MOONLEDS introduces you to some of its frequently asked questions.

Why choose COB?

1. The compactness of the LED array makes it easy to use in different places. Traditional DIP lamps are cheap but bulky. Compared to DIP Diode Led lamps, it is more portable and flexible for outdoor applications.

2. The high intensity and uniform luminosity of the on-board chip can provide a good experience for users. It meets the needs of high standard lighting applications.

3. Compared to SMD lights, led cob panel the entire chip requires only one circuit and two contacts, while SMD lights require a circuit for each diode contained in the chip. Such a circuit configuration allows for installation without causing blowing.

How to choose a LED COB lamp?

To choose an LED video light panel like a COB LED panel, here are some factors you need to care about:

Light output: Light output is determined by the lumens of light. The higher the lumen number, the brighter the light can be seen.

Lighting method: There are a variety of COB LED lights on the market today. Some of them are able to change the lighting mode according to the different requirements of the scene.

Power supply: Before buying a light, it is necessary to determine its power requirements. If the light is portable, it needs a stable power supply.

Internal cooling device: Since cob led chips generate a lot of heat, a good heat sink is essential.

What is the difference between regular SMD LEDs and COB LEDs?

First, you need to have a basic understanding of surface mount device (SMD) LEDs. They are the most widely used LEDs on the market today. LED chips are firmly integrated into printed circuit boards and are widely used due to their adaptability, even in notification lights for smartphones. the number of diodes and contacts on an SMD LED chip is one of their most distinguishing features.

There may be more than two contacts on an SMD LED chip. On one LED, up to three diodes can be found, each with its own circuit. Each circuit will use an anode and cathode, resulting in 2, 4 or 6 connections on the LED.

What is the lifetime of COB LEDs?

The lifespan of COB LEDs depends on how they are used and how much heat they are exposed to. The average rated lifespan of COB LEDs is 50,000 hours. This assumes that the COB LEDs works for an average of 12 hours per day.

Why are COB LEDs so important when using battery power?

When building a battery-powered lighting system, there is always a trade-off between high-quality lumen output (brightness) and battery-powered runtime. If you are using the same size batteries, the higher quality of lighting you want, the shorter the run time. With the advent of COB LED technology, this has become less of a concern.

COB LEDs with very low power can produce extremely high quality, ultra-bright light. As a result, COB LED-based lighting systems can be powered for long periods of time using relatively small and lightweight lithium-ion battery packs.

What are the applications of COB LEDs?

* COB LEDs will be used primarily as a solid-state lighting (SSL) replacement for metal halide bulbs or halogen lamp in streetlights, high bay lights, downlights, and high output track lights.

* Because of their wide-angle beams, they can be used for LED lighting fixtures placed in living rooms and halls.

* Special lighting such as television studio, studio lighting, film & photography lighting.

* Other applications include basic lighting in passageways and hallways, fluorescent lamp replacements, LED lights, light bars, smartphone camera flashes, etc.

Conclusion

COB LEDs are becoming increasingly popular in lighting applications as designers discover the advantages of using COB LEDs over typical standard LEDs. It's hard not to consider them in the construction of any LED light application. They are brighter, less power consumed, and provide a higher quality light.
