Adjusting device for illumination brightness of showcase

Abstract

The utility model discloses a showcase illumination brightness adjusting device, which comprises a showcase main body, a mounting plate and a heat dissipation mechanism, the surface of the showcase main body is provided with the mounting plate, one side of the mounting plate is fixedly connected with the heat dissipation mechanism, the inner side of the heat dissipation mechanism is provided with an air outlet, the outer side of the heat dissipation mechanism is provided with a small motor, and the small motor is fixedly connected with the mounting plate. And a cooling fan is arranged on the inner side of the small motor, and a lighting mechanism is arranged on one side of the cooling mechanism. By arranging a cooling fan and an exhaust outlet, the device can avoid aging of internal equipment and circuits caused by long-time high-temperature baking of the adjusting mechanism, the service life of the adjusting mechanism is prolonged, and meanwhile, the influence of heat radiation generated by a lighting lamp on exhibits in the showcase can be avoided; and a reflecting mirror surface can be formed when the cooling fan rotates, light rays emitted from the air opening are reflected through the reflecting mirror, and the situation that the light rays are refracted to the outer side of the device through the air outlet to affect the viewing experience of viewers is avoided.
