Problems solved by technology

Because in the existing technology, the light emitted by the light source has to undergo two or more reflections before it can exit the lampshade, and each reflection will consume a certain amount of light energy, resulting in a low light energy utilization rate of the lamp.

Embodiment Construction

[0023] In order to make the purpose and features of the present invention more obvious and understandable, preferred embodiments are given in conjunction with the attached Figure 2-4 , the present invention will be further described.

[0024] See figure 2 , which is a schematic cross-sectional view of a light reflector provided by an embodiment of the present invention. As shown in the figure, the reflective arc surface of the reflector 22 includes a first reflective arc surface 220, a second reflective arc surface 221 and a joint 222, wherein the joint 222 connects the first reflective arc surface 220 and the second reflective arc surface 221, and the first reflective arcuate surface 220 and the second light reflective arcuate surface 221 are mirror symmetrical at the joint. The cross-sectional profile of the reflector 22 can be regarded as obtained by vertically pulling a symmetrical curve at the symmetrical axis 30 to a certain height after optical design.

Abstract

The invention discloses a reflector as well as a lamp using the reflector and an installation method thereof. The reflector comprises a first reflective arc surface, a second reflective arc surface and a connecting part, wherein the first reflective arc surface and the second reflective arc surface are in mirror symmetry at the connecting part. When the reflector is installed for use, the opening direction of the reflector is arranged in the projecting direction of a double rail light source, and the connecting part of the reflector is also probed into the double rail light source and exceeds the geometric center of the double rail light source, therefore, light emitted by the light source can be emitted out from the reflector through at most only once reflection, and the optical energy use rate of a whole lamp optical system is improved.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a lamp reflector which uses a double-rail light source for lighting. Background technique [0002] At present, the reflectors used in double-track light sources generally have the problem of unreasonable design, resulting in low light energy utilization. Such as figure 1 As shown, the lamp 10 includes a light source 11 and a reflector 12. The light source 11 is placed in the reflector 12, and the light rays a, b, and c emitted by the light source 11 are reflected by the inner surface of the reflector 12 for multiple times and then exit the reflector 12. In the prior art, the light emitted by the light source needs to undergo two or more reflections before it can exit the lampshade, and each reflection will consume a certain amount of light energy, resulting in a low light energy utilization rate of the lamp.
