Structure substrate of COB light source modules with flip LED chips

Abstract

The invention discloses a structure substrate of COB light source modules with flip LED chips. The substrate is provided with a plurality of COB light source modules, multiple flip LED chips are encapsulated on the COB light source modules, and the spacing distance between every two adjacent LED chips is larger than the thickness of the LED chips. According to the COB light source module structure substrate of the flip LED chips, due to the fact that the space distance between every two adjacent LED chips is larger than the thickness of the LED chips, the defect that COB light sources are arranged too densely is avoided, heat emission is facilitated, and meanwhile the cooperative work effect among the LED chips is optimized to a certain degree; the side edge of each LED chip is made to emit complete light as far as possible, and therefore the efficiency of the COB light sources is improved.

Description

technical field [0001] The invention relates to a COB light source structure, in particular to a COB light source module structure substrate with flip-chip LED chips. Background technique [0002] The COB light source can be simply understood as a high-power integrated surface light source, which is a high-efficiency integrated surface light source technology in which LED chips are directly attached to a high-reflection mirror metal substrate. The product features of the COB light source are: electrical stability, circuit design, and optical design. , The heat dissipation design is scientific and reasonable; the use of heat sink technology ensures that the LED has an industry-leading thermal lumen maintenance rate (above 95%); it is convenient for the secondary optical matching of the product to improve the lighting quality; high color rendering, uniform light emission, no spot, Healthy and environmentally friendly; easy to install, easy to use, reduce the difficulty of lamp...

Problems solved by technology

[0004] For high-power light sources with a power generally between 50W and 250W, such as high-power LED street lights, LED tunnel lights, LED floodlights, LED explosion-proof lights, LED industrial and mining lights, etc., multiple low-power COB light sources are often combined to achieve Reach the specified power requirements, but the COB light sources in the prior art are often too concentrated, not only will generate a large amount of heat accumulation, but also block each other between the COB light sources, so that the efficiency of the COB light source is not high, that is, the utilization rate is not high
