Something you should know about LED COB light

What is an LED COB light?

LED COB light, which stands for "Chip-on-Board," is a type of LED consisting of an array of LED chips mounted on a substrate, such as silicon carbide. It is known for its compact design, energy efficiency, and exceptional uniformity of brightness, making it a popular choice among photographers and filmmakers.

Features

1. Homogeneous luminosity

Compared to other LEDs, COB lights provide excellent light uniformity. The beam they emit is concentrated and clean. When used to create shadow effects, the outlines of the shadows are more distinct than those produced by other LED types.

2. Compactness

The COB LED chip comprises multiple diodes mounted on a single substrate, with narrow gaps between each diode. This design reduces its size, making it versatile for various applications.

3. Energy efficiency

When compared to other types of LEDs, COB LED lights offer greater energy efficiency, producing brighter light output while consuming less energy.

Merits of COB LED pocket lights

1. Durability
The thermal resistance of COB LEDs is low, ensuring good conductivity, reliability, and lifespan. Since the LED chips are directly mounted on the substrate, spot welding is unnecessary, reducing the light's failure rate. Overall, this design enhances its durability.

2. Good lighting effect
Due to the arrangement of mounted LED chips, the COB LED array functions as a single light source, delivering high intensity and homogeneous luminosity. Its exceptional uniformity makes COB LED lights an excellent option for those needing high-quality lighting.

3. Energy saving
When delivering the same lumens of brightness, COB LED lights consume less energy compared to other LED types.

4. Space saving
The circuit configuration of COB packages effectively conserves space.

5. Simple installation
LED chips on board require only one circuit and two contacts for the entire chip, making installation convenient.

Drawbacks: Heat dissipation issue

Despite their excellent performance in luminosity and energy efficiency, a significant drawback of LED COB lights is their heat dissipation issue. Since all LED chips converge on a single substrate, they generate considerable heat during operation. If this heat builds up, it can negatively affect the light's performance. Additionally, active cooling systems can produce noise, which can be problematic for filmmakers who need to record sound. Therefore, a good heat sink is essential for smooth operation and to minimize breakdowns.

Applications

COB LED light sources are suitable for various indoor and outdoor lighting applications. They can provide universal illumination across industrial, residential, architectural, and other settings. For example, they can serve as street lights, spotlights, and strip lights. Their homogeneous luminosity plays a crucial role in filmmaking and photography.

Why choose a COB LED video light?

1. Flexibility
The compact design of the COB LED array makes it easy to use in various settings. Traditional DIP lights may be inexpensive but tend to be bulky. In contrast, COB lights are more portable and flexible, especially for outdoor use.

2. Outstanding light effect
The high intensity and homogeneous luminosity provided by COB LEDs offer users a superior experience, meeting the demands of high-standard lighting applications.

3. Simplified installation
The COB LED light panel requires only one circuit and two contacts for the entire chip, whereas SMD lights necessitate one circuit for each diode within the chip. This configuration simplifies installation.

How to choose an LED COB light?

When selecting a LED video light panel like a COB LED panel, several factors should be considered:

• Light output: The brightness of a light is measured by lumens. A higher lumen count indicates a brighter light.
• Lighting mode: Various COB LED lights on the market can change lighting modes according to different scene requirements.
• Power supply: It is crucial to identify the power supply requirements before purchasing a light. A stable power supply is necessary for portable lights.
• Internal cooling device: Given that COB LED chips produce substantial heat, a good heat sink is essential.
