Anti-glare blackboard lamp

Abstract

The invention relates to an anti-glare blackboard lamp comprising a housing, a light source mounted on the housing, a lens mounted on the housing, a reflector plate mounted on the housing, and an anti-glare plate mounted on the housing; the housing comprises a body, a first shading part located on one side of the body and a second shading part located on the other side of the body; and the first shading part is located on the side, away from a blackboard, of the body, the length of the first shading part is larger than the length of the second shading part, the reflector plate is located on the inner side of the first shading part, and the anti-glare plate is connected with the tail end of the first shading part. According to the anti-glare blackboard lamp provided by the invention, through the arrangement of the first shading part, the second shading part, the lens and the reflector plate, the light emitted by the light source is all irradiated on the blackboard, and the lighting effect on the blackboard is improved; and on the other hand, the first shading part and the anti-glare plate are arranged, so that light rays are prevented from being directly irradiated to the human eyes, the glare value is reduced, and the human eyes are protected.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to an anti-glare blackboard lamp. Background technique [0002] At present, classrooms generally use bracket lamps as lighting fixtures. The actual utilization efficiency of the lamps is low, and it will produce a lot of glare. Low and very poor uniformity. [0003] In order to solve the above problems, some classroom lamps use double-reflector blackboard lamps. Two fluorescent tubes emit light onto the blackboard through two fixed reflectors. To the ground, reflected to the human eye, resulting in a great waste of glare and energy, and the structure of the lamp is relatively complicated, which is not conducive to practical application. [0004] There are also some blackboard lights that cancel the reflector by adding lens components. Although the lighting effect on the blackboard has been improved, the brightness of the lens is too large and the distance from the blackboard is i...

Problems solved by technology

[0002] At present, classrooms generally use bracket lamps as lighting fixtures. The actual utilization efficiency of the lamps is low, and it will produce a lot of glare. Low and extremely poor uniformity

[0003] In order to solve the above problems, some classroom lamps use double-reflector blackboard lamps. Two fluorescent tubes emit light onto the blackboard through two fixed reflectors. to the ground, reflected to the human eye, resulting in a great waste of glare and energy, and the structure of the lamp is relatively complicated, which is not conducive to practical application

[0004] There are also some blackboard lights that cancel the reflector by adding lens components. Although the lighting effect on the blackboard has been improved, the brightness of the lens is too large and the distance from the blackboard is installed too far, resulting in increased glare in the direction of students and teachers. The installation method sometimes blocks the projector, causing inconvenience in teaching
