Embodiment 1

[0028] A dip coating method for preparing dimmable LED lamp shades, the preparation steps are as follows:

[0029] Step 1, soak the LED lamp into the first coating solution, put it into the muffle furnace for constant temperature curing for 2 hours after dipping and pulling, and obtain the reflective film layer;

[0030] Step 2, put the LED lamp with reflective film into the reaction kettle, then add the second coating solution until the LED lamp is submerged, seal and pressurize the internal cycle aeration reaction for 3 hours, and obtain the secondary film layer;

[0031] Step 3, putting the LED lamp after secondary coating into a muffle furnace for sintering reaction for 4 hours, and putting it under an ultraviolet lamp for light treatment for 1 hour after cooling to obtain a double-coated LED lamp;

[0032] The quality formula of described the first coating solution is as follows:

[0033] 10 parts of n-ethyl silicate, 20 parts of absolute ethanol, 2 parts of dispersant, ...

Embodiment 2

[0045] A dip coating method for preparing dimmable LED lamp shades, the preparation steps are as follows:

Abstract

The invention discloses a dip coating method for preparing dimmable LED lamp shades. The reflective film layer is obtained by dipping and pulling on the surface of the LED lamp, and then the secondary film layer is obtained by sealing and pressurizing internal circulation aeration reaction. Finally, it is sintered in a muffle furnace and treated with ultraviolet light to obtain a double-coated LED lamp. The thin film layer prepared by the invention can effectively solve the brightness problem and ensure soft light on the surface of the LED lamp.

Description

technical field [0001] The invention belongs to the technical field of lighting lamps, and in particular relates to a dip coating method for preparing dimmable LED lamp shades. Background technique [0002] LED lamps are currently the most commonly used lighting fixtures. However, with the needs of use, the light intensity of LED lamps is also changing. Therefore, LED lamps with light adjustment functions have become the darling of the market. The light is dazzling white light, and the visual comfort as lighting is not as good as that of high-pressure sodium lamps. [0003] In addition, the dazzling white light is very glaring. In the range of the LED light, the human eye will cause eye pain due to the strong light, and even cause temporary blindness. Yellow light is in the middle of the visible light band and is the most sensitive to human eyes, so for LED lights to have a real competitive advantage, it must also emit soft yellow light. Contents of the invention [0004...
