Embodiment Construction

[0043] Such as Figure 1 to Figure 3 As shown, a schematic diagram of the manufacturing process of an embodiment of the present invention is shown;

[0044] Such as figure 1 As shown, it is step 1), this step provides a substrate 1, and the substrate 1 includes from bottom to top:

[0045] A single-layer aluminum bottom plate 10, the aluminum bottom plate 10 is made of more than 99.85% aluminum material, and is located at the bottom layer; there is a fixed layer 20 on it;

[0046] The silver layer 30 is covered on the upper surface of the fixed layer 20 and cooperates with it by adopting a coating process of physical vapor deposition (PVD-Coating); the purity of the silver layer 30 is greater than 99.9%, about 99.95%, and its upper surface is Reflective surface, that is, the structure of the mirror surface;

[0047] There is an oxide layer 40 on the upper surface of the silver layer 30. The oxide layer 40 can adopt various processes. In this solution, the upper surface of t...

Abstract

Provided are an LED lighting module structure and method for manufacturing the same, characterized in that: a substrate (1), from the bottom to the top, sequentially comprises : a single layer aluminum base plate (10) located at the bottom; and a fixation layer (20) formed on the aluminum base plate (10); and a silver layer (30) which formed by physical vapor deposition, coated and matched the top surface of the fixation layer (20); the purity of the silver layer (30) is more than 99.9% and the top surface of the silver layer (30) is a reflective surface; and a reflective oxide layer (40) is located on the top surface of the silver layer (30). An insulated glue layer (50) is formed on the top surface of the oxide layer (40); and then a LED chip (60) is adhered to the top surface of the glue layer (50); at last, the LED lighting module is made by a cure process.

Description

technical field [0001] The invention relates to the field of LED lighting, in particular to a structure of an LED lighting module and a manufacturing process thereof. Background technique [0002] The rapid development of LED has led to its increasingly popular application in the lighting field. A large number of LED light sources have been used in various traditional lighting fixtures / equipment to achieve light output, thus directly replacing traditional lamps without changing the electrical connection and geometric structure. , to obtain better light color performance and service life. [0003] Compared with traditional light sources, LED light sources have unique characteristics. In addition to the advantages of high luminous efficiency, good color rendering, and low temperature rise, they also have their obvious defects. The more obvious point is that the single luminous body of the LED light source is small in size and high in luminous density. If it is necessary to ob...
