LED lamp for classroom

Abstract

The LED lamp comprises a mounting plate and an LED lamp assembly. The LED lamp assembly comprises a lamp frame, a lightproof plate, a reflecting film, a light guide plate, a diffusion film and a prismatic crystal plate, wherein the lightproof plate, the reflecting film, the light guide plate, the diffusion film and the prismatic crystal plate are arranged on the inner side of the lamp frame in sequence, and an LED light source emitting light towards the light guide plate is arranged on the side face of the light guide plate; the glare control layer is provided with a hollow hole, a hollow layer is arranged in the light guide plate, and reflection supporting mechanisms which are used for guiding light emitted by the LED light source to the light outlet face of the light guide plate and canlimit and support the upper end face and the lower end face of the hollow layer are arranged in the hollow layer. Through arrangement of the glare control layer, illumination of the LED classroom lampis more uniform, and the anti-dazzling effect is better; the reflection support mechanism in the hollow layer of the light guide plate gives consideration to the power consumption of the light sourceand the uniform light generation effect.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to an LED lamp for classrooms. Background technique [0002] LED lamps have been widely used in the prior art and have become a common lighting device in people's daily life. For example, in the lighting of rooms, classrooms and other occasions, using LED ceiling lamps for lighting is a common lighting solution in the prior art. [0003] As a lighting appliance, classroom lights create a good classroom light environment for learning and make an important contribution to the formation of a good learning environment. However, at present, the bottom of most classroom lamps uses a grid plate to prevent the glare of the light. Because the distance and height of the grid plate are difficult to adjust to completely prevent the glare, the overall lighting effect of the classroom lamp is not good.

AI Technical Summary

Problems solved by technology

However, at present, the bottom of most classroom lamps uses a grid plate to prevent the glare of the light. Because the distance and height of the grid plate are difficult to adjust to completely prevent the glare, the overall lighting effect of the classroom lamp is not good. Good, the visual effect is not good, and the thickness of the lamp that uses the grid plate to prevent glare is generally relatively large, which leads to high production costs of the lamp

[0004] Furthermore, the light guide plate of the LED backlight panel is usually a flat plate, and the astigmatism effect is not ideal, and the light enhancement sheet located above the diffusion film is also usually a planar structure, the light extraction efficiency is not good, and the brightness is not high enough.
