Reflector and lamp with same

Abstract

The invention is applicable to the field of lighting, and provides a reflector and a lamp. The reflector comprises a bowl-shaped body, the blow-shaped body is provided with a center shaft and two through holes symmetrically relative to the center shaft, a first reflecting surface is arranged on the inner surface of the body, and is provided with two ridge-shaped subsurfaces, the two ridge-shaped subsurfaces are symmetrically relative to the center shaft and a connection line between the centers of the two through holes, and are consistent to the generatrix of the body in direction, and a second reflecting surface is arranged at the bottom of the body, is connected with the first reflecting surface, and bulges toward the reflector. As the subsurfaces are ridge-shaped, that is, are formed by angularly abutting the two reflecting surfaces, when light rays shine on the reflecting surfaces, the light rays are reflected to reflection areas on the two sides of the subsurfaces to avoid shining of the light rays, and in addition, as the second reflecting surface bulges toward a light emitting port of the reflector, the light rays on the second reflecting surface are reflected on the first reflecting surface, and then are projected out through the first reflecting surface. Therefore, the reflector and the lamp can prevent the light rays from being reflected on a light source to cause temperature raise of the light source effectively.

Description

technical field [0001] The invention belongs to the field of lighting, in particular to a reflector and a lamp comprising the reflector. Background technique [0002] In the prior art, there are various types of lamps, and there are also many kinds of light sources for the lamps. In the prior art, there is a downlight using a double-ended quartz metal halide lamp as the light source. The two ends of the double-ended quartz metal halide lamp are inserted into the two ends of the reflector. The light emitted by the light source is reflected by the reflector and projected to the distance. However, since the double-ended light source is fixed in the reflector laterally through its two ends, when the traditional reflector is used to reflect the light, it is bound to be inevitable. There will be part of the light directed at the illuminant and both ends of the light source, which not only affects the utilization rate of light energy, but more importantly, the heat of the light sou...

Problems solved by technology

[0003] The object of the present invention is to provide a reflector, aiming to solve the problem that the lamps with double-ended light sources are easily damaged due to reflected light irradiating the light source
