Embodiment Construction

[0050] Combine below Figure 2 to Figure 9 , the present invention is further described:

[0051] Such as figure 2 As shown, the "chip on board" in the high-power LED lighting module of the chip on board refers to the chip directly packaged on the uniform temperature plate, and its specific structure is as follows:

[0052] Attach the capillary tissue 12 to the inner wall of the vapor chamber 1, seal the vapor chamber of the support, 11, and leave an injection port 13, and coat a layer of high thermal conductivity insulating medium on the upper surface of the vapor chamber 1 to form An insulating dielectric layer 32.

[0053] Then a circuit layer 31 is made on the insulating medium layer 32, and the first stage of the process is completed through the processes of die bonding, gold wire bonding, reflector support 43, and phosphor powder 41 (needed only for white light source).

[0054] To complete the structure of the above process, add working fluid to the injection port 1...

Abstract

The invention relates to a high-power LED (light-emitting diode) lamp module of a chip-on-board. The lamp module comprises an LED light emitting unit, a uniform temperature plate (1) and a heat radiating structure (2), wherein the LED light emitting unit is fixed on the uniform temperature plate (1), the heat radiating structure (2) is fixed below the uniform temperature plate (1); and the lamp module is characterized in that the heat radiating structure (2) and the uniform temperature plate (1) transfer heat by a graphite paste (8). In the high-power LED lamp module, the graphite paste arranged between the heat radiating structure and the uniform temperature plate has excellent heat transfer performance; and compared with a structure in the prior art, the high-power LED lamp module has the advantages that a layer of heat conducting silica gel is omitted, and the heat radiating efficiency is greatly increased.

Description

technical field [0001] The invention relates to an LED lamp, in particular to a chip-on-board high-power LED lamp module. Background technique [0002] With the continuous improvement of the luminous efficiency of LED light-emitting chips, it is just around the corner that LED lighting will replace traditional lighting. In addition to the luminous efficiency of the LED chip itself, the luminous efficiency of the lamp is also critical to the packaging process and the design of the optics, mechanism, drive power, and heat dissipation of the lamp. [0003] The optical design lies in the design of the light distribution of the light source of the lamp according to the needs of the user. In addition, the light transmission and reflection design of the lens and reflector is related to the light effect of the lamp. The conversion efficiency of the driving power is high, which means that the power consumption is low, and the light efficiency will naturally be improved. A good heat...
