Detailed Description

The embodiments of the present invention are described in detail below to make the advantages and features of the present invention easier to understand by those skilled in the art, thereby making more clear and definite definitions of the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

Example 1

Referring to fig. 1-9, a novel anti-glare eye-protecting lamp for classrooms comprises a shell 1, a long frame 2, a short frame 3, a grid 4 and a diffusion plate 6; a plurality of LED lamp belts 5 are arranged in the shell 1 and used as light sources; the long side of the shell 1 is connected with the long frame 2; the short side of the shell 1 is connected with the short frame 3; the diffusion plate 6 is fixed in the housing 1 and is positioned at the opposite side of the LED lamp strip 5; the grid 4 is fixed by the long frame 2 and the short frame 3; the diffusion plate 6 is a PC plate, has a thickness of 0.5mm-2mm, and has a frosted surface. The surface of the diffusion plate 6 is frosted, so that disordered refraction of light rays is facilitated, and the glare effect of a light source is greatly reduced.

The grid grating 4 is provided with a plurality of diamond-shaped grids 401 which are uniformly arranged; four corners of the rhombic grid 401 are all set to be round corners 402. After being refracted by the diffusion plate 6, the light of the light source is emitted out through the rhombic grids 401 of the grid grids 4, so that the coverage angle of the light of the eye-protection lamp is reduced, and the glare effect is further reduced.

The cross sections of the long frame 2 and the short frame 3 are the same; the long frame 2 and the short frame 3 are both provided with a first clamping groove 7 and a second clamping groove 8; the first card slot 7 and the second card slot 8 are both C-shaped; the first clamping groove 7 is matched with the long side and the short side of the shell 1; the second clamping groove 8 is matched with the long side and the short side of the grid 4. The long frame and the short frame of the eye-protecting lamp are convenient to install and disassemble.

The short frame 3 is detachably connected with the short side of the shell 1. When needs wash net grid 4, only need dismantle the short frame 3 of eye-protecting lamp both sides, take out net grid 4 along second draw-in groove 8 wash can, need not to dismantle whole eye-protecting lamp.

The grid 4 is a splicing structure and is divided into a plurality of blocks in the extension direction. The length of the grid 4 is too long, a person stands on the ladder, and the grid is inconvenient to pull outwards, and the length of the grid 4 is not easy to exceed 600mm because the arm spread of the person is limited and the person is inconvenient to clean.

The inner sides of the four sides of the shell 1 are provided with third clamping grooves 101, and the third clamping grooves 101 are matched with the diffusion plate 6. The diffusion plate 6 is thin and can be slightly bent, four edges of the diffusion plate 6 are inwards shrunk after the diffusion plate is slightly bent, and the diffusion plate can be simply inserted into or pulled out of the third clamping groove 101.

The utility model discloses during the use, luminous behind the 5 switch on in LED lamp area, light jets out through the 6 refraction backs of diffuser plate, through the rhombus net 401 of net grid 4 again, very big reduction the glare effect of light source, reach the purpose of protection user's eyes.

After long-term use, more dust falls on the grid 4, and only short frames 3 on two sides of the eye-protecting lamp need to be detached, and the grid 4 is cleaned after being drawn out along the second clamping groove 8.

The above, only be the preferred embodiment of the present invention, not for limiting the present invention, all the technical matters of the present invention should be included in any slight modification, equivalent replacement and improvement made to the above embodiments by the technical matters of the present invention within the scope of the present invention.
