Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-4, the utility model relates to an anti-glare blackboard lamp, which comprises a strip-shaped shell 1, wherein the lengths of the shell 1 and a lamp 5 are not less than the length of a blackboard 11, a fixed seat 3 is hinged at the top of the shell 1, the blackboard lamp is fixedly arranged at the top of the blackboard 11 through the fixed seat 3, and the shell 1 and the fixed seat 3 are rotatably connected through a damping rotating shaft 13, so that the inclination angle of the shell 1 can be conveniently adjusted;

the bottom opening of casing 1, the inboard slope of casing 1 is provided with lamps and lanterns 5, lamps and lanterns 5 slope towards the position at blackboard 11 place, the lamp socket department of lamps and lanterns 5 is provided with convex lens 9, convex lens 9 just faces lamps and lanterns 5, make the illuminating light 12 that lamps and lanterns 5 sent shoot out parallelly after the refraction of convex lens 9, prevent that illuminating light 12 from being fan-shaped and dispersing, improve luminance, one side that the direction of illumination of lamps and lanterns 5 was kept away from to the bottom of casing 1 is provided with lens hood 2, lens hood 2 is used for preventing a small amount of light leaks and shoots out to blackboard 11 the place ahead region.

The lamp 5 comprises an LED lamp panel 7, an LED lamp bead 6 is arranged on the LED lamp panel 7, a reflecting cover 8 is arranged on the outer side of the LED lamp panel 7, a convex lens 9 is arranged at the port of the reflecting cover 8, the reflecting cover 8 plays a role of primary condensation, and diffuse reflection of illumination light 12 generated inside the shell 1 is reduced.
