Combined reflector and lamps

Abstract

The invention is suitable for the technical field of lamp production, and provides a light reflecting cover and a lamp. A combined-type light reflecting cup comprises a tail end light reflecting cup, an intermediate light reflecting piece and a front end light reflecting cup, wherein the upper end of the tail end light reflecting cup is movably connected with the lower end of the intermediate light reflecting piece in a stretching manner; the upper end of the intermediate light reflecting piece is movably connected with the lower end of a front end light reflecting cup in a stretching manner; the lamp adopts the above combined-type light reflecting cup. With the adoption of the light reflecting cover and the lamp provided by the invention, variable focal length can be realized through a structure of a reflector, so that the condition that a focusing auxiliary structure is arranged in the lamp can be avoided, the structure of the lamp is simplified, the production cost is reduced, and the universality of the reflector and the lamp on different light source components is promoted.

Description

technical field [0001] The invention belongs to the technical field of lamps, and more particularly relates to a combined reflector and a lamp using the combined reflector. Background technique [0002] In order to make full use of the limited light energy emitted by the light source in the lamp, a reflector is installed in the lamp, and the reflector is used to control the illumination distance and illumination area of ​​the main light spot, so as to obtain an ideal light distribution. However, the reflector of the existing lamp is generally an integral structure. When zooming, it is necessary to move the reflector relative to the light source as a whole through other auxiliary adjustment structures arranged in the lamp to obtain an ideal light distribution. In this way, the auxiliary adjustment structure makes The structure of the entire luminaire becomes complex, and the manufacturing process will increase accordingly, which will increase the cost of the luminaire; in add...

AI Technical Summary

Problems solved by technology

However, the reflectors of existing lamps are generally integral structures. When zooming, other auxiliary adjustment structures installed in the lamps must be used to move the reflector as a whole relative to the light source in order to obtain an ideal light distribution. This auxiliary adjustment structure makes The structure of the entire lamp becomes complicated, and its manufacturing process will increase accordingly, which will increase the cost of the lamp; in addition, the fixed reflector is not universal, and once manufactured, it is only suitable for one shape and size The light distribution of the light source, when the lamp is replaced with a light source of another shape and size, it is necessary to separately make a matching reflector, which will also cause complicated material management and waste of lamp cost
