Reflector lamp provided with hemispheric diffusion shell and adjustable in angle

Abstract

The invention discloses a reflector lamp provided with a hemispheric diffusion shell and adjustable in angle. Central light strength and overall luminous efficiency of the reflector lamp are improved by arranging light sources on the obverse side and the reverse side of a heat conduction base plate. Simultaneously, heat dissipation effects of the whole reflector lamp are greatly improved by arranging semiconductor chilling plates between the heat conduction base plate and a heat conduction pillar. Additionally, a heat conduction worm is meshed with a worm gear which is hinged in a long groove in one side of a lamp head heat dissipation body along the radial direction, and the worm can be conveniently driven to move up and down by rotating the worm gear, and then light emitting positions of the light sources can be adjusted, and accordingly light emitting angles of the whole reflector lamp can be changed through a light reflecting cup. Simultaneously, the hemispheric diffusion shell arranged at the top of the second light source enables light rays emitted by the second light source to be even, and glare is difficult to generate. The reflector lamp provided with the hemispheric diffusion shell and adjustable in angle is simple in structure, high in luminous efficiency, good in heat dissipation effect and adjustable in angle, and difficultly generates the glare.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a spotlight with a hemispherical diffusion cover and an adjustable angle. Background technique [0002] Spotlights in the prior art are generally provided with a light source at the bottom of the luminous cup to emit light toward the mouth of the cup. Due to the limited space at the bottom of the luminous cup, it is generally difficult to increase the luminous efficiency of the entire lamp by increasing the number of light sources. In addition, due to The light source is set to the bottom of the reflector, so it is difficult to improve the heat dissipation effect. In addition, since the position of the light source is fixed, the light emitting angle of the whole lamp cannot be changed by changing the position of the light source. Contents of the invention [0003] The object of the present invention is to provide a spotlight with simple structure, high luminous efficiency, go...
