Embodiment 1

[0021] A method for preparing an automotive indication and anti-discoloration LED lamp, comprising the following steps:

[0022] Step 1) Fixing the crystal, gluing the light-emitting body on the bracket through the crystal-bonding glue and baking to fix it, so as to facilitate the position setting;

[0023] Step 2) welding wires, welding the lead wires to form a conductive circuit, so that the LED lamp can shine brightly;

[0024] Step 3) Prepare the colloid, crush the raw rubber cake and grind it into a rubber cake powder, then add YAG powder and graphene powder and stir evenly. When stirring, put the rubber cake powder, YAG powder and graphene powder into the same container Stir with a stainless steel rod for 20 minutes. When stirring, first stir clockwise for 5 minutes, then counterclockwise for 5 minutes, then clockwise for 5 minutes, and finally counterclockwise for 5 minutes to obtain a mixed powder. The above method can quickly complete the uniform stir;

[0025] Step...

Embodiment 2

[0031] The difference between Embodiment 2 and Embodiment 1 is that, when the above-mentioned crystal-bonding glue is configured, it includes the following components in parts by weight: 80 parts of epoxy resin, 20 parts of toughening resin, 10 parts of nano-silicon carbide, chromium carbide 1 part, 7 parts of graphene liquid, 7 parts of ceramic micropowder, 2 parts of cationic curing agent, 5 parts of urea and 1 part of isocyanate.

Embodiment 3

[0033] The difference between Embodiment 3 and Embodiment 1 is that the above-mentioned crystal-bonding glue contains the following components in parts by weight when it is configured: 90 parts of epoxy resin, 25 parts of toughening resin, 15 parts of nano-silicon carbide, chromium carbide 5 parts, 5 parts of graphene liquid, 9 parts of ceramic micropowder, 3 parts of cationic curing agent, 9 parts of urea and 3 parts of isocyanate.

Abstract

The invention discloses a preparation method of automotive indicating discoloration-preventing LED lamps. The method comprises the steps as follows: Step 1, die bonding: light-emitting bodies are glued on a support through die bonding glue and are baked and fixed; Step 2, lead welding: a lead is welded to form a conductive circuit; Step 3, preparation of a rubber body: a raw material rubber cake is brushed and ground into rubber cake powder, then YAG powder and graphene powder are added and evenly stirred, and mixed powder is obtained; Step 4, cake production: the mixed powder is placed into a cake pressing die for extrusion and is taken out, and a rubber cake is obtained; Step 5, forming: the rubber cake is melted through a forming machine and injected onto the support, a formed rubber body is formed, and a formed lamp panel is obtained; Step 6, cutting: the formed lamp panel is cut, single LED lamps are obtained, and then finished products are obtained through dehumidification. The LED lamps prepared with the method have the relatively long service life, and the color and the brightness of light cannot be weakened after the lamps are used for 1,000 h.

Description

technical field [0001] The invention relates to the field of LED lamps, in particular to a method for preparing an LED lamp for automobile indication and anti-discoloration. Background technique [0002] Ordinary 0805 vehicle-mounted LED indicators are molded with epoxy resin cakes when packaged. After 1000 hours of use, the color and brightness of the light will attenuate. Product requirements are not met. The display effect of the vehicle indicator light is greatly reduced, and the effect of prompting relevant vehicle information of the vehicle LED indicator light is affected. It is more difficult for the indicator light to maintain the original brightness and original color. Contents of the invention [0003] The purpose of the present invention is to overcome the above problems existing in the prior art, and to provide a method for preparing an automobile indicator LED lamp that prevents discoloration. The LED lamp prepared by the present invention has a long service ...
