Background

According to the national light requirements of classrooms, the average illumination of a common classroom reaches more than 300LX, the average illumination of an art classroom reaches more than 500LX, and the uniformity reaches more than 0.7. Most of traditional classroom lamps adopt an energy-saving day lamp tube and a common LED lamp tube, the light distribution adopts the principle of direct symmetric irradiation and partial reflection, local high brightness of the lamp often appears easily, the uniformity of light emitted by the lamp is low, the hidden danger of glare is formed, the service life is long, the visual fatigue of eyes is easy to cause, and the eyesight is reduced.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a grid diffuse reflection lamps and lanterns improves the homogeneity of classroom lamp light.

The utility model adopts the technical proposal that: the utility model provides a grid diffuse reflection lamps and lanterns, includes drain pan, micrite board, grid board and two LED lamp strips, the drain pan has the lower part opening, two LED lamp strip parallel mount is in the both sides of drain pan, micrite board and grid board are by last opening part that sets gradually at the drain pan under to, the grid board is formed by the mutual concatenation of a plurality of grid board units.

Furthermore, the hole pattern of the honeycomb holes is a polygonal structure, the hole diameter of the honeycomb holes gradually decreases from top to bottom, and the through holes of the honeycomb holes are obliquely arranged from top to bottom.

Further, the hole type of the honeycomb holes is a hexagonal structure.

Further, the opening of microcrystalline plate and grid plate and drain pan is connected through the frame between, the upper portion and the mutual lock joint of drain pan of frame, microcrystalline plate draw-in groove and grid plate draw-in groove have set gradually from top to bottom in the lower part inboard of frame, four bights of frame pass through the foot rest involution.

Further, the bottom shell is made of a light-transmitting material.

Furthermore, a diffusion film is attached to the upper surface of the microcrystalline plate.

The utility model has the advantages that:

1. the light-emitting surface of the classroom lamp is formed by combining the microcrystalline plate and the grid plate, and the emitted light is uniform and soft, so that the eyes of students can be protected.

2. Two lamp strips are arranged in the bottom shell at intervals, so that the emitted light is prevented from having shadows.

3. The grating plate is formed by splicing a plurality of grating plate units, which is beneficial to reducing the production cost of the grating plate.

Detailed Description

The grille diffuse reflection lamp shown in fig. 1 and fig. 2 includes a square bottom case 100, a micro-crystal plate 200, a grille plate 300 and two LED light bars 400, the bottom case 100 has a lower opening, the two LED light bars 400 are installed in parallel on two sides of the bottom case 100, the micro-crystal plate 200 and the grille plate 300 are sequentially disposed at the opening of the bottom case 100 from top to bottom, and the grille plate 300 is formed by mutually splicing a plurality of grille plate units.

Light that LED lamp strip 400 sent produces diffuse reflection's effect when the micrite board 200 for the light that sees through forms the feel of natural soft, and through the effect of grid board 300, make light more soft, avoid producing dizzy light. The eyesight of the personnel in the classroom is protected. The grid plate 300 is formed by splicing a plurality of grid plate units, which is beneficial to reducing the production cost of the grid plate.

Further, as shown in fig. 3 and 4, the panel of the grating plate unit is formed by arranging and combining a plurality of hollow honeycomb holes 310 to form a honeycomb hole pattern 310 with a polygonal structure, the pore diameter of the honeycomb hole 310 gradually decreases from top to bottom, and the through holes of the honeycomb hole 310 are arranged in an inclined manner from top to bottom.

Grid plate 300 adopts hexagonal honeycomb holes, and honeycomb holes 310's aperture diminishes by last to down gradually, and honeycomb holes 310's through-hole lets light softer more by last to the slope setting down, has better degree of consistency.

The microcrystalline board 200 and the grating board 300 are connected to the opening of the bottom case 100 through the frame 500, the upper portion of the frame 500 is fastened to the bottom case 100, the microcrystalline board clamping grooves 510 and the grating board clamping grooves 520 are sequentially formed in the upper portion and the lower portion of the inner side of the lower portion of the frame 500, and four corners of the frame 500 are sealed through the foot stand 600.

The microcrystalline plate 200 and the grid plate 300 are connected to the opening of the bottom case 100 through the frame 500, so that the microcrystalline plate 200 and the grid plate 300 can be conveniently installed, and when the microcrystalline plate 200 or the grid plate 300 is damaged, the microcrystalline plate 200 or the grid plate 300 can be conveniently disassembled, assembled and maintained.

The bottom case 100 is made of a transparent material, so that the classroom lamp has a glittering and translucent visual effect when in use, and is beneficial to emitting certain light rays towards other directions.

The upper surface of the microcrystalline board 200 is attached with a diffusion film, and the diffusion and scattering of light are improved by the diffusion film, so that the light is softer.

Of course, the present invention is not limited to the above-mentioned embodiments, and those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of the present invention, and such equivalent modifications or substitutions are included in the scope defined by the claims of the present application.
