3. Disregarding Beam Angle

The beam angle determines the spread of light from the LED. A narrow beam angle (15°-30°) is perfect for focused lighting applications, such as spotlights or task lighting. A wider beam angle (60°-120°) is better for general illumination. Not considering the beam angle can lead to uneven lighting and shadowed areas.

4. Not Considering Heat Dissipation

Heat dissipation is crucial for the longevity and performance of COB LEDs. Poor heat management can lead to reduced efficiency and a shorter lifespan. Ensure that the COB LEDs you choose have adequate heat sinks or cooling mechanisms to manage heat effectively.

5. Ignoring the CRI (Color Rendering Index)

CRI measures the ability of a light source to reveal the true colors of objects. COB LEDs with a high CRI (80 and above) provide more accurate color representation, essential for applications like retail, photography, and medical environments. Overlooking CRI can result in lighting that distorts colors and affects the visual experience.

6. Failing to Check Power Requirements

Different COB LEDs have varying power requirements. Ensure that your power supply matches the voltage and current requirements of the LEDs. Using an incompatible power supply can lead to poor performance, flickering, or even damage to the LEDs.

7. Overlooking the Importance of Drivers

LED drivers regulate the power supply to the LEDs, ensuring consistent performance and protecting against power fluctuations. Selecting COB LEDs without considering the quality and compatibility of the drivers can lead to reliability issues and shortened LED lifespan.

8. Neglecting Manufacturer Reputation and Reviews

Not all COB LEDs are created equal. Manufacturer reputation and customer reviews provide valuable insights into the quality and reliability of the products. Opt for reputable manufacturers with positive reviews to ensure you're getting high-quality COB LEDs that meet your expectations.

What is COB Led?

COB lamp is a kind of LED lamp. COB is the abbreviation of Chip on Board in English, which means the packaging technology of chip on board. It is a high-efficiency integrated surface light source technology in which multiple LED chips/bare chips are directly attached to a high-reflectivity mirror metal substrate (such as silicon carbide). This creates a large LED chip with compactness, energy-saving, and excellent uniform brightness, which is loved by related professionals such as filmmakers and photographers. Generally, COB chips have 9 or more diodes. However, no matter how many diodes there are, COB LED lights have a single circuit with several contacts. Because it has the characteristics of easier dimming and color adjustment, high brightness, anti-glare, and can well solve the problems of chromatic aberration and heat dissipation, COB light sources have now been widely used in commercial lighting and other fields.

What are the advantages of COB light source?

1、Cost saving

In terms of cost, compared with previous discrete light sources, COB light source modules can save the cost of device packaging in actual lighting applications, as well as the cost of light engine module production and the cost of secondary light distribution. In a lighting system with the same function, the overall cost can be saved by about 15%.

2、Strong performance

In terms of performance, the COB light source module can also effectively solve the glare problem caused by the combination of discrete light source devices through reasonable design and technology. You can also add a red chip combination to ensure that the efficiency of the light source is not reduced, and the life of the used equipment is guaranteed, while also improving the color rendering of the light source. The COB light source is integrated by multiple diodes, with a large focus area, a single chip can cover a large area, and the light concentration is high. The use of transparent lenses reduces light loss, improves clarity, and helps improve light efficiency.

3、Convenient application and mass production

In the actual application process, COB light source modules can also make the installation and production of lighting manufacturers easier and more convenient. With the current level of technology and advanced equipment, large-scale COB light source module production can be carried out.

4、Energy saving and environmental protection
