Scattering lampshade of LED lamp

Abstract

A scattering lampshade of an LED lamp comprises a reflector and a shade body. The reflector and the shade body are connected to form a cavity, and the cavity is provided with a space for containing the LED lamp. The reflector protrudes inwards, and the shade body is concave outwards. The protruding face of the reflector is full of hemispherical protrusions, and the protruding face and the surfaces of the hemispherical protrusions are coated with reflective layers. The concave side of the shade body is full of granular protrusions, and the shade body and the granular protrusions are made of transparent materials. According to the scattering lampshade of the LED lamp, the reflector protrudes inwards, light of an internal light source is scattered in all directions, and meanwhile the protrusions are arranged on the protruding face of the reflector, so the light irradiated on the protruding face can be further scattered; meanwhile, the granular protrusions are arranged on concave side of the shade body, light rays passing the shade body can be further dispersed.

Description

technical field [0001] The invention relates to the field of LED lighting, in particular to a diffuser lampshade for an LED lamp. Background technique [0002] In recent years, due to the successful development of white light LED lamps, LEDs have begun to enter the lighting industry. The Chinese name of LED is light-emitting diode, which belongs to cold light source. Compared with incandescent lamps and fluorescent lamps, it has the advantages of energy saving, long life, no heat, and impact resistance. Compared with fluorescent lamps, it also has the advantages of no flickering, fast startup speed, and no pollution to the environment. It is an ideal light source for a new generation. [0003] At present, LEDs have begun to be used in flashlights, indicator lights, and outdoor decorative lights. But the LED light-emitting device of prior art will be widely used in household lighting lamps and is equal to the daily lighting lamps and lanterns that human body is closer, als...

AI Technical Summary

Problems solved by technology

But the LED light-emitting device of prior art will be widely used in household lighting lamps and is equal to the daily lighting lamps and lanterns that human body is closer, also has following defect: the light source that a plurality of LEDs forms is all scattered point light sources, and the light source that each LED forms Point light sources are very dazzling, and the irritation to the eyes is particularly severe, so that it causes damage to the eyes, especially the eye health of children.

Since this technical problem has not been well resolved, LEDs cannot be used in household and indoor lighting and other daily lighting fixtures that are closer to the human body.

[0004] The utility model patent with the authorized notification number CN2549315Y discloses a color-changing energy-saving lamp. The lampshade used in the lampshade has uniform and non-distributed fine grooves on the inner wall of the lampshade. , but for white light LED lamps, after repeated tests by the applicant, the problem of glare has not been well resolved, that is to say, the light pollution of LEDs has not been eliminated, and LEDs still cannot be used for home and indoor lighting, etc. Daily lighting fixtures that are close to the human body, and the light source is scattered and not concentrated, the light efficiency and brightness are not ideal, the light loss is relatively large, and the light range is also significantly reduced
