Problems solved by technology

However, because the light emitted by the light source is scattered in the reflective bowl, a large part of the light energy cancels each other in the bowl, so the lighting effect with such a reflective bowl is low.

Embodiment Construction

[0019] figure 2 is a perspective view of a reflective cup according to an embodiment of the present invention, image 3 For its top view, Figure 4 Its partial section view. refer to figure 2 , 3 , 4. The reflective cup 100 includes a cup body 10 and a cup bottom 20, wherein the cup bottom 20 is provided with an opening 201 for allowing the light source 200 to extend into the reflective cup from the hole, and the upper part of the reflective cup 100 has an opening 30 for The light emitted from the light source 200 is emitted.

[0020] Refer to attached Figure 5 , the cup body 10 is bowl-shaped, specifically, the shape of its inner wall can be: first define a small focal length first parabola y 2 = 2p 1 x, the shape obtained by rotating the parabola 360 degrees around a vertical rotation axis B. The cup body 10 has a certain thickness, and the shape of the outer wall of the cup body is not limited, as long as it can match the shape of the lighting device used.

Abstract

The invention relates to a reflection cup which includes a cup body and a cup bottom; wherein, the cup bottom is provided with an opening used for leading a light source to enter into the reflection light from the opening; the upper part of the reflection cup is provided with a cut used for the beam emitted by the light source to be jetted; the cup body is of a bowl shape and the shape of the inner wall thereof is a shape obtained by firstly defining a first parabola and then rotating the parabola for one circle along the vertical rotating shaft in the center of the opening of the cup bottom; a plurality of reflection concave layers are arranged on the inner wall of the cup body; the quality of the reflection concave surfaces of any reflection concave layer is equal to that of the other; besides, each reflection concave layer includes a plurality of reflection concave surfaces of the same shape which are mutually close to each other; any reflection concave surface in each reflection concave layer is provided with a structure which allows the light emitted by the light source to be jetted from the opening by one reflection.

Description

technical field [0001] The invention belongs to a lighting product, in particular to a reflective cup used in a lamp. Background technique [0002] Generally, the reflective cup used for lighting fixtures has an overall smooth reflective mirror surface, which produces a concentrating effect on the light emitted by the lamp, which has an adverse effect on human eyes. At present, the reflective cup with floodlight effect is sandblasted on its inner surface, so that the light emitted by the light source to the sandblasted reflective surface is diffusely reflected, thereby achieving floodlighting. This kind of reflective cup has some disadvantages, such as large loss of light energy, low reflective light efficiency, uncontrollable direction of reflective light, and low light source utilization. [0003] The Chinese Utility Model Patent No. ZL200520031706.0 discloses a reflective cup. The inner surface of the reflective bowl has a continuous convex or concave spherical surface. ...
