Guangmai Technology is proffesional in making the 9W COB LED Chip Flip Diode.
Features of COB light source
The new fourth-generation light source of COB light source can also be said to be an evolution of the fourth-generation light source, because its light-emitting body is a chip light-emitting diode. But the difference between the two lies in the packaging technology. The fifth-generation light source adopts the world's most cutting-edge high-tech packaging technology, encapsulating ordinary light-emitting diodes in a small plane, so it is called a surface light source. Compared with the point light source, under the same wattage, the area of the surface light emitting surface is reduced by up to 10 times or more than the point light emitting surface area, and the heat generated is correspondingly reduced by 5-10 times, which greatly reduces the energy consumption. And the problem of light source exhaustion caused by heat dissipation problems, and makes the assembled lamp housing lighter and simpler. The light-emitting angle and effect of the surface light source are better played and applied under the refraction and condensing of the lens, so that the light-emitting angle can be adjusted arbitrarily, thereby forming a secondary light distribution. However, because of the large light-emitting area of the point light source, it is difficult to use the lens, and the light-emitting angle becomes a "dead spot".
LED uses a low-voltage power supply, the power supply voltage is between 6-24V, using AC to DC. It varies from product to product, so it is a safer power supply than using high-voltage power supplies, and is especially suitable for public places. Compared with incandescent lamps with the same luminous efficiency, the energy consumption is reduced by 80%, which is an energy-saving product. Its light source area is very small, the minimum diameter of the circle is 30mm, the maximum diameter is 80mm, and the thickness is 1mm. It is anti-fall and anti-vibration, can be prepared into various shapes of devices, and is suitable for variable environments. All cob plane light sources have high usability. And its long life span can reach more than 50,000 hours. The response time of cob planar light source incandescent lamp is millisecond, and the response time of LED lamp is nanosecond, so its response time is very fast. The cob plane light source is also a low-carbon and environmentally friendly product, without harmful heavy metal substances. It can change color by changing the current. The light-emitting diode can easily adjust the energy band structure and band gap of the material through chemical modification methods to achieve red, yellow, green, blue, and orange multicolor light. For example, a red LED at low current can turn into orange, yellow, and finally green as the current increases.
