Abstract

An anti-dazzle optical classroom lamp comprises a lamp shell, an LED lamp bar connected to the lamp shell and an optical mask which is arranged at an interval from the LED lamp bar and forms a light ray divergence space; the optical mask forms the light cup of matrix arrangement, the light cup has the periphery wall and goes into the plain noodles and connect in periphery wall income plain noodles upper portion and the sunken arc income plain noodles of centre down to and light passes through the periphery wall and goes into the plain noodles and pass material itself and form interior cup exit face and the protruding arc exit face that passes through the arc income plain noodles and form, light follows the periphery wall is gone into plain noodles and arc income plain noodles and is entered into the translucent material and change beam angle and homodisperse and directly export down to realize anti-dazzle. The anti-glare plastic plate can be formed by a plastic plate with the light transmittance of more than 60 percent through a plastic suction mold, is simple in process and structure, stable in structure, uniform and direct in output of light rays after being refracted through a light cup, and has the characteristics of effective anti-glare and the like; therefore, it has excellent performance in technical, practical and economical aspects.

Description

Anti-dazzle optics classroom lamp

Technical Field

The utility model relates to an anti-dazzle optical classroom lamp.

Background

According to patent retrieval and market research, the existing classroom lamp generally adopts a reflecting row mirror and a lamp tube, a light source is directly irradiated into a classroom, and light rays close to the lower part of the light source are strong, so that glare is caused.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem of providing an anti-dazzle optical classroom lamp which can adopt a plastic plate with the light transmittance of more than 60 percent to be molded through a plastic sucking mould, has simple process and structure, stable structure, uniform and direct output of light rays through refraction of a light cup, effective anti-dazzle and the like.

In order to achieve the above object, the technical scheme adopted by the utility model is to provide an anti-dazzle optical classroom lamp, which comprises a lamp shell, an LED lamp bar connected to the lamp shell, and an optical mask which is arranged at a distance from the LED lamp bar and forms a light ray divergence space;

the optical mask forms a light cup arranged in a matrix, the light cup is provided with an outer peripheral wall light inlet face, an arc light inlet face which is connected to the upper part of the outer peripheral wall light inlet face and is sunken towards the lower center, and

the light penetrates through the light inlet face of the outer peripheral wall and penetrates through the material to form an inner cup emitting face and a convex arc emitting face formed by the arc light inlet face, and the light enters the light-transmitting material from the light inlet face of the outer peripheral wall and the arc light inlet face to change the beam angle and output the light uniformly in a dispersed manner so as to realize anti-glare.

In one or more embodiments of the present invention, the optical mask is formed by using a plastic plate with a light transmittance of more than 60% and using a plastic mold.

In one or more embodiments of the present invention, the light source of the LED light bar is more than 25mm from the optical mask.

Compared with the background technology, the utility model has the following effects:

due to the adoption of the scheme, the anti-glare plastic plate can be formed by a plastic suction mold through a plastic plate with the light transmittance of more than 60 percent, is simple in process and structure, stable in structure, uniform and direct in-down output of light rays after being refracted by the light cup, and has the characteristics of effective anti-glare effect and the like; therefore, it has excellent performance in technical, practical and economical aspects.
