One-piece high-power LED integrated light source with more than two convex mirrors and its manufacturing process

Abstract

The invention discloses an integrated high-power LED (Light Emitting Diode) light source with more than two convex mirrors and a manufacturing process thereof, wherein the integrated LED light source comprises a substrate and more than two LED chips or more than two sets of LED chip modules; the LED chips or the LED chip modules are installed on the substrate; independent convex mirrors are formed on the LED chips or the LED chip modules by being quantitatively pressed through an automatic high-temperature high-pressure die; and a film bonded to the substrate is formed between the adjacent convex mirrors in the quantitative pressing and forming processes by adopting the automatic high-temperature high-pressure die. The manufacturing process mainly comprises the steps of quantitatively pressing and forming the convex mirrors by adopting the automatic high-temperature high-pressure die, and forming a silicone film between every two convex mirrors. According to the invention, the cost of the manufacturing process is low; the technological process is simple; the light condensation effect of the manufactured integrated high-power LED light source is good; consistency of light colours is good; air vulcanization on the integrated high-power LED light source is effectively reduced; and the service life of the integrated LED light source is greatly increased.

Description

technical field [0001] The invention relates to a high-power LED integrated light source and its manufacturing process, in particular to an integrated high-power LED integrated light source with more than two convex mirrors and its manufacturing process. Background technique [0002] Due to the energy saving, high efficiency and long life of LED, it is widely used, such as for stage decoration, landscape decoration, indoor lighting, display and so on. Due to the different uses of LEDs, there are also great differences in their structures and forms, such as individual LED light sources, LED integrated light sources, etc., and with people's demand for power, color, etc., the development of LED integrated light sources is becoming more and more rapid. It is also used more and more widely. For example, an LED integrated light source is disclosed in the patent document whose application number is 201120545826.8, the application date is December 22, 2011, and the authorized annou...

AI Technical Summary

Problems solved by technology

In addition, the process of fixing the LED chip or LED chip module first, clamping the mold, and then injecting the glue is adopted. If the temperature of the mold, the position of the glue injection port, and the position of the air outlet are not appropriate, it will affect the silicone or resin. Fluidity, there may be a phenomenon that the spherical die head in the lens forming die is not filled with silicone or resin. As long as one of the spherical lenses has the above problems, the quality of the entire LED integrated light source will be affected, or even scrapped. Therefore, the molded Authentic rate is difficult to control

Have again, adopt above-mentioned mold structure molding spherical lens, because when processing lens forming mold, need to improve the intensity of lens forming mold, therefore, the distance between spherical die head can not be set too small, like this, the spherical lens that molds comes out The distance between them is also relatively large, therefore, the light concentrating effect of the LED integrated light source is not good
