Embodiment 1

[0019] According to 1% nano-silica, 0.5% nano-aluminum nitride, 1% dibutyltin dilaurate, 0.3~0.5% N, N'-diphenylbenzidine diamine, 0.3% light stabilizer UV-196, 2% of EL1000 silicone LED light diffusing agent with a particle size of 5 μm, 1% of nano-scale light scattering particles SC803 with a particle size of 300 μm, and the balance is the mass percentage of the thermoplastic substrate (polycarbonate). After the components, firstly mix nano-silica, nano-aluminum nitride and dibutyltin dilaurate evenly, then add the rest of the components, mix and shape to get the lampshade, which is a conventional technical means in this field, so I won’t go into details here .

Embodiment 2

[0021] According to 3% nano-silica, 1% nano-aluminum nitride, 3% dibutyltin dilaurate, 0.5% N, N'-diphenylbenzidine diamine, 0.5% light stabilizer UV-196, 4% EL1000 silicone LED light-diffusing agent with a particle size of 10 μm, 2% of nano-scale light-scattering particles SC803 with a particle size of 800 μm, and the balance is the mass percentage of the thermoplastic substrate (polyethylene terephthalate). After weighing each component, first mix nano silicon dioxide, nano aluminum nitride and dibutyltin dilaurate evenly, then add the remaining components, mix and shape to obtain the lampshade, which is a conventional technical means in the field. So I won't go into details here.

Embodiment 3

[0023] 2% nano-silica, 0.7% nano-aluminum nitride, 2% dibutyltin dilaurate, 0.4% N, N'-diphenylbenzidine diamine, 0.4% light stabilizer UV-196, 3% EL1000 silicone LED light diffusing agent with a particle size of 8 μm, 1.2% of nano-scale light scattering particles SC803 with a particle size of 400 μm, and the balance is the mass percentage of the thermoplastic substrate (polymethyl methacrylate). After each component, firstly mix nano-silica, nano-aluminum nitride and dibutyltin dilaurate evenly, then add the remaining components, mix and shape to obtain the lampshade, which is a conventional technical means in this field, so it will not be described here repeat.

[0024] The light transmittance of the plastic lampshade of the LED lamp of the present invention is 88-93%, the haze is 93%, the luminous angle increases from 180° to 270-320°, the light transmittance is high, the light guiding effect is good, and the loss of light efficiency is small. It has good balance between i...

Abstract

The invention discloses a plastic lampshade for an LED lamp. The plastic lampshade for the LED is made of the following components in mass percentage: 1-3% of nano-silicon dioxide, 0.5-1% of nano-aluminum nitride, and 1-3% of dibutyltin Dilaurate, 0.3~0.5% N, N'-diphenylbenzidine diamine, 0.3~0.5% light stabilizer UV-196, 2~4% EL1000 silicone LED light diffusing agent, 1~2% nano Grade light scattering particles SC803, the balance is thermoplastic substrate. The LED lamp plastic lampshade of the present invention has good high temperature resistance performance, stable color quality, high light transmittance, good light guiding effect, less light efficiency loss, and can expand the light-emitting angle of the LED lamp boards arranged in a plane. The invention also discloses a method for preparing the plastic lampshade of the LED lamp, which has simple process steps, strong operability and is suitable for industrialized production.

Description

technical field [0001] The invention relates to an LED lampshade, in particular to a plastic lampshade for an LED lamp and a preparation method thereof. Background technique [0002] In recent years, due to the rapid development of the LED industry, LED lamps have gradually replaced traditional lighting fixtures. For the lampshade outside the LED lamp, the light transmittance and intensity are its important characteristics, which directly affect the use effect of the LED lamp. [0003] Chinese patent application publication number CN103148438A, the Chinese patent application publication date of 2013.06.12 discloses a plastic lampshade capable of emitting light and transmitting light, which uses one or several transparent or translucent thermoplastic resins as the base resin, containing 10%~30% strontium aluminate luminescent pigment with a particle size of 30μm~120μm, excited by rare earth europium ions and dysprosium ions. The lampshade has poor high-temperature resistanc...
