Abstract

The utility model discloses a light dispersion shade for an LED lamp, wherein the light dispersion shade which is transparent has an upper part provided with LEDs and a light dispersion surface provided with a light dispersion body which is also transparent, wherein the light dispersion body is closely adjacent to a straight triangle convex strip, or a spiral triangle convex strip, or a circular triangle convex strip, or a pyramid or a taper; when the light rays emitted by the LEDs pass through the light dispersion body of the light dispersion surface, the utility model can refract and disperse the light rays, making the light rays emitted by the LEDs soft and not dazzle eyes of people, thereby resolving the glaring problem of the LED lamp.

Description

The diffuser of LED lamp

Technical field

The utility model relates to a kind of lampshade, particularly a kind of diffuser of LED lamp.

Background technology

LED is the abbreviation of light emitting diode, and at present, a lot of as the lighting of light emitting source with LED, the light that LED sends has dazzle, and people's eyes are had dazzle and glare effect.

Summary of the invention

The purpose of this utility model provides a kind of diffuser of LED lamp, and this diffuser can solve the dazzle of LED, overcomes the shortcoming that led light source is dazzle the eyes.

The utility model includes a diffuser, this diffuser is the transparent body, diffuser top is provided with LED, astigmatic face at diffuser is provided with astigmatism body, and astigmatism body is the transparent body, if astigmatic face is the plane, then astigmatism body is tight adjacent rectangular triangle raised line, or tight adjacent spiral triangle raised line, or tight adjacent circle triangle raised line, or tight adjacent pyramid or circular cone.

If astigmatic face is a cambered surface, then astigmatism body is tight adjacent triangle raised line, or pyramid, or circular cone.The utility model can make light that LED sends by the astigmatism body on the astigmatic face time, and refraction and scattering take place, and makes the light that sends from LED soft, and the people can not dazzle the eyes, and has solved the dazzle problem of LED lamp.
