Problems solved by technology

[0002] Among the existing technologies, the ceramic COB light source technology is widely used. This technology has the advantages of high thermal conductivity and high light efficiency, but the disadvantage of this technology is that the cost of the material base is high, and it is not suitable for large-area products.
Moreover, in the prior art, the structure of the high-brightness COB light source and the dimmable COB light source are relatively complicated, and the production process is also very complicated, resulting in high production costs of this type of COB light source.
In addition, there is no high-brightness and dimmable COB light source in the existing market

Abstract

The invention discloses a high-brightness dimmable COB light source. The high-brightness dimmable COB light source comprises a plurality of bonding pads used for reinforcement, a plurality of LED chips with different light colors, a substrate, a retaining wall, a positive electrode and a negative electrode, wherein the retaining wall is fixed on the substrate, and the retaining wall divides the substrate into a plurality of light emitting areas; the LED chip with different light colors are fixed in different light emitting areas respectively; the LED chips located in different light emitting areas are electrically connected with the positive electrode and the negative electrode independently; the retaining wall is a transparent; and the bonding pads are uniformly distributed on the substrate. The high-brightness dimmable COB light source provided by the utility model is provided with a plurality of light emitting areas, two adjacent light emitting areas are isolated by transparent box dam glue, thereby enabling light emitted by each of the light emitting areas to penetrate through the retaining wall and transmit to one or more adjacent light emitting areas. Each of the light emitting areas can adjust current independently, thereby realizing a function of controlling the color temperature and the brightness of each of the light emitting areas independently.

Description

technical field [0001] The invention relates to the field of COB light sources, in particular to a high-brightness dimmable COB light source, a spotlight COB process, and a fluorescent lamp COB process. Background technique [0002] Among the existing technologies, the ceramic COB light source technology is widely used. This technology has the advantages of high thermal conductivity and high light efficiency, but the disadvantage of this technology is that the cost of the material base is high, and it is not suitable for large-area products. Moreover, in the prior art, the structure of the high-brightness COB light source and the dimmable COB light source are relatively complicated, and the production process is also very complicated, resulting in a high production cost of this type of COB light source. In addition, there is no high-brightness and dimmable COB light source in the existing market. Contents of the invention [0003] Aiming at the deficiencies in the above t...
