Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0022] Such as Figure 1 ~ Figure 3 As shown, a reflective cup provided by an embodiment of the present invention is used in a lamp. The reflective cup includes a cup body 100, and the cup body 100 includes a first reflective ring 110 in the shape of a truncated cone and is connected with the first reflective ring. The second reflective ring 120 docked with 110, the second reflective ring 120 includes a plurality of reflective sub-rings 121 that are sequentially stacked and adjacent to each other, and the inner wall of the first reflective ring 110 is provided with a plurality of circular arcs. Sh...

Abstract

The invention is suitable for the technical field of illumination and discloses a reflecting cup and a lamp comprising the same. The reflecting cup comprises a cup body, wherein the cup body comprises a first reflecting ring having a circular truncated cone shape and a second reflecting ring in butt joint with the first reflecting ring; the second reflecting ring comprises a plurality reflecting subrings with tapering caliber sizes; the plurality reflecting subrings are overlapped with and adjacent to one another sequentially; the inner wall of the first reflecting ring is provided with a plurality of arc-shaped reflecting convex points; and each reflecting subring comprises an inclined reflecting surface. The lamp comprises the reflecting cup and light-emitting members positioned in the reflecting cup. The reflecting convex points and the plurality of reflecting subrings with the tapering caliber sizes and overlapped with and adjacent to one another sequentially are arranged on the cup body, so the reflecting cup and the lamp comprising the same provided by the invention have the advantages of improving the illumination efficiency of the lamp and contributing to energy conservation and environmental protection on the premise of guaranteeing semi-light intensity angle of the lamp.

Description

technical field [0001] The invention belongs to the technical field of lighting, in particular to a reflective cup and a lamp provided with the reflective cup. Background technique [0002] At present, the reflective surfaces of the reflectors in the lamps are arc-shaped, and the busbars of the reflectors are arc-shaped or parabolic. The reflective surfaces are treated with frosting and orange peel to increase the diffuse reflection of the reflective surfaces. To achieve the purpose of increasing the half-light intensity angle of the lamp. However, after the reflective surface is treated with frosting or orange peel, the lighting efficiency of the lamp will be reduced, and the lighting efficiency is only about 50%, which is not conducive to energy saving and environmental protection. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the above-mentioned prior art, and provide a reflector and a lamp equipped with the ...
