Product
High-power COB light source is a high-power integrated surface light source. By directly attaching the LED chip to a high-reflective mirror metal substrate, a high-light-efficiency packaging technology is achieved. This technology eliminates the traditional bracket concept and reduces processes such as electroplating, reflow soldering, and patch placement, thereby reducing cost and complexity.
Technical features
High light efficiency: The high-performance COB light source can reach 150 lumens per watt or even higher, and the light efficiency is very high.
Heat dissipation performance: The use of heat sink process technology ensures that the LED has industry-leading thermal lumen maintenance rate (95%).
High color rendering index: The color rendering index can reach 120lm/w, and the luminous angle is above 120°.
Even light emission: Even light emission, no spots, healthy and environmentally friendly.
Easy to install: Simple to install and easy to use, reducing the difficulty of lamp design and maintenance costs.
Application scenarios
High-power COB light sources are widely used in various lighting equipment, including LED street lights, LED spotlights, etc. Its advantages include:
High light efficiency: high luminous efficiency and low energy consumption.
Good color rendering: High color rendering index, soft light, not harmful to eyes.
Flexible control: The spectral composition can be controlled, suitable for local or accent lighting.
Fast response: Fast switching speed, no delay and flicker.
Packaging and thermal technology
The packaging process of high-power COB light sources includes research on the status of phosphors to ensure the light color indicators of the light sources. In terms of heat dissipation, by optimizing the shape and size of the radiator and adopting a clamped heat dissipation solution, the intensity of natural convection is enhanced and the problem of heat concentration is solved.
