LED light source module and assembling method thereof

Abstract

The invention discloses an LED light source module which comprises an LED lamp string, a base plate, a radiator and a transmitting device, wherein the LED lamp string is welded with the base plate in series; the base plate and the transmitting device are fixed on the radiator; the base plate welded with the LED lamp string is arranged between the transmitting device and the radiator; and a cavity is formed between the transmitting device and the base plate welded with the LED lamp string. The LED light source module is characterized in that a liquid medium is injected in the cavity formed between the transmitting device and the base plate welded with the LED lamp string. The LED light source module has the advantages of effectively and rapidly dissipating the LED heat, improving the utilization rate of the LED rays and improving the light emitting efficiency of the LED lamps.

Description

technical field [0001] The invention relates to an LED light source module and an assembly method thereof. Background technique [0002] After several years of development, the performance of LED has been continuously improved, but the service life of LED has been constrained by the thermal environment. If the LED with the best performance does not have a reasonable heat dissipation scheme to dissipate heat from the LED lamp, its optical performance will not last long. will continue to decrease thereafter. [0003] LED light has the characteristic of directional lighting. When it is made into LED lamps, it often needs secondary light distribution design to change the light emitting direction of LEDs, so that LED lamps can be properly illuminated in a specific environment. [0004] Heat dissipation technology and light distribution technology have always been the core technologies of the LED industry. [0005] At present, the heat dissipation method adopted by LED lamps on ...

AI Technical Summary

Problems solved by technology

However, this method has a structural defect that the LED cannot be tightly combined with the lens, which means that the light must pass through the air medium before entering the lens, which will cause part of the light to be reflected back, and will also affect the accuracy of the light distribution design.

[0007] like figure 1 Shown is a module with a conventional heat dissipation structure and light distribution structure. Due to mechanical assembly problems, there is a sealed air medium where the LED lamp 1 and the lens 2 cannot be tightly combined. It is difficult for the air to circulate inside, and the thermal conductivity of the air Extremely low, so traditional conventional modules can only rely on the radiator 3 on the back of the LED lamp to dissipate heat (the direction of heat flow is shown by the guide arrow in the figure), the heat dissipation effect is not good, and the light must pass through the air before entering the lens 2 Medium, which will cause part of the light to be reflected back, and will affect the accuracy of the light distribution design
