Detailed Description

The teaching chamber lamp of the present invention will be further described with reference to fig. 1 to 3.

A classroom lamp, characterized by: comprises a rear shell 1, a frame 2, a grid plate 4 and a light-emitting component 5. Four pairwise symmetrical top surface connecting plates 3 are arranged at the top of the frame 2, each top surface connecting plate 3 is of a Z-shaped structure, namely, a bottom plate of each top surface connecting plate 3 is fixed on the frame 2 through bolts, and a top plate is used for connecting the top surfaces. The rear shell 1 is fixed on the upper opening of the frame 2, namely, the middle part of the rear shell 1 is raised upwards, and the edge of the rear shell 1 is attached to the step on the top surface of the frame 2 and is fastened through screws. The middle part of backshell 1 rises upwards, light emitting component 5 includes the lamp area and sets up a plurality of LED lamp pearls on the lamp area, and the lamp area sets up on the interior roof of backshell 1 to this light emitting component 5 passes through the under shed light-emitting of frame 2. The grid plate 4 is fixed in the frame 2 or on a lower opening of the frame 2 for light beams of the light emitting assembly 5 to pass through. In this embodiment, the grid plate is fixed in the frame.

In order to improve the convenience of the installation of the utility model on the top surface of the classroom, a strip-shaped connecting port 31 is arranged on the top plate of the top surface connecting plate 3, and an inlet and outlet 311 with a widened size is arranged at the middle position of the connecting port. When the teaching room lamp is disassembled and assembled, the bolt is arranged on the hanging roof in an inverted state, the head of the bolt penetrates through the connecting port through the inlet and outlet 311, the teaching room lamp is horizontally moved, and the head of the bolt is staggered with the inlet and outlet 311, so that the top surface connecting plate 3 is hoisted on the corresponding bolt; when the teaching room lamp needs to be detached, the bolt can be separated from the connecting port only by horizontally moving the teaching room lamp and enabling the inlet and the outlet 311 to correspond to the head of the bolt, so that the operation is simple and the connection is stable.

The embodiment is further configured as follows: a supporting edge 22 is formed on the inner wall of the frame 2, the lower surface edge of the grid plate 4 is supported on the supporting edge 22, and the rear shell 1 is provided with an elastic abutting part 11 which is bent downwards and abuts against the top surface of the grid plate 4, so that the grid plate 4 is fixed in the frame 2.

The embodiment is further configured as follows: the grid plate 4 has a plurality of grid holes 411, and the inner wall of the lower opening of each grid hole 411 is inclined 4111 to form a flared structure. The structure can achieve the effect of uniform light emission.

In this embodiment, in order to save material loss, the upper hole wall of each grid hole 411 is disposed as an indent 4112, and the frame 2 is a hollow structure 21, so as to reduce the overall material loss and the production cost.

The embodiment is further configured as follows: and a diffusion plate 6 is arranged above the grid plate 4, and a light source of the light-emitting assembly enters the grid holes after passing through the diffusion plate. The diffuser plate 6 is fixed between the grid plate 4 and the elastic pressing portion 11 so that the diffuser plate and the grid plate 4 are fixed at the same time.

Based on the above mechanism, when the light-emitting component 5 emits light, the light beams of the light-emitting component 5 can be uniformly emitted through the grid holes 411 on the grid plate 4 and the grid holes 411 uniformly and densely distributed on the grid plate 4, so that the uniformity of the whole emitted light is improved, and the effects of preventing dizziness and protecting the vision of students are achieved.
