Abstract

A light source reflector comprises a conical reflective surface and a flat reflective surface connected to the periphery of the conical reflective surface. The conical reflective surface is formed with a plurality of protruding or concave unit curved surfaces. The flat reflective surface can be provided with a plurality of refractive protrusions, thereby improving the optical efficiency and light mixing effect of the reflector for light.

Description

light source reflector

technical field

The utility model relates to a reflector structure used to match light sources such as light emitting diodes (LED, Light Emitting Diode) or light bulbs to reflect light.

Background technique

Generally, lamps used for lighting purposes will be equipped with reflectors to improve the brightness of the lighting.

Fig. 4 shows an existing reflector structure, which integrally forms the reflector A with injection molding technology, the reflector A includes a conical reflective surface A2, and the peripheral surface connected to the conical reflective surface A2 The flat reflecting surface A1 has a hole in the center of the tapered reflecting surface A2 where light sources such as LEDs or light bulbs can be installed. When the light source located in the center of the conical reflector A2 emits light, part of the light will be directly projected out of the reflector, and part of the light will be projected to the conical reflective surface A2, and then the light will be reflected by the conical reflective surface A2. The flat reflective surface A1 can also reflect part of the light, but because the flat reflective surface does not directly receive the light projected by the light source, its reflection effect is poor.

The tapered reflective surface A2 of the aforementioned conventional reflector is a curved mirror surface. Although it has a good function of reflecting light, it has not been able to effectively improve the refraction and light mixing effects of light.

Utility model content

The main purpose of this utility model is to improve the deficiencies of the traditional light source reflector, which has poor refraction light and light mixing effect.

The main feature of the utility model is that a plurality of small unit curved surfaces are arranged on the conical reflective surface of the reflector, and each unit curved surface is also a smooth mirror surface to replace the traditional simple mirror surface. When light is projected onto these unit curved surfaces At the same time, in addition to having a good effect of reflecting light, it can also effectively refract light and mix light effectively.

The technical means of the utility model is to integrally form the reflector by using injection molding technology, so that the reflector includes a conical reflective surface and a flat reflective surface connected to the periphery of the conical reflective surface. The conical reflector A plurality of protruding or concave unit curved surfaces are formed on the surface at the same time, and the flat reflective surface can be provided with a plurality of refraction protrusions. The aforementioned flat reflective surface and conical reflective surface can be formed into smooth mirror surfaces by electroplating, thereby improving The optical efficiency and light mixing effect of the reflector for light.

Detailed ways

The following is a more detailed description of the embodiments of the present invention in conjunction with the drawings, so that any technical personnel familiar with the technology can implement it after studying this patent specification.

Referring to Fig. 1 to Fig. 3, the preferred embodiment of the present utility model is to use injection molding technology to integrally form the reflector 1 with a hole in the center, so that the reflector includes a conical reflector 12, and is connected to The flat reflective surface 11 on the periphery of the conical reflective surface 12, the conical reflective surface 12 is formed with a plurality of unit curved surfaces 121 at the same time. It is concave into the conical reflective surface, thereby forming a surface shape similar to a spider web on the conical reflective surface. The flat reflective surface 11 can be provided with a plurality of refraction protruding points 111, and the refraction protruding points 111 can be triangular pyramids, cones, ... etc. of appropriate sizes; the aforementioned flat reflective surface 11 and conical reflective surface 12 can be Electroplating forms its surface into a smooth mirror surface.

Figure 3 shows the reflector 1 of the present utility model installed with a light source 2, the light source 2 can be an LED module or a general light bulb; the light source 2 is installed in the preset hole in the center of the reflector 1 ; When the light source 2 emits light, a part of the light will be directly projected out of the reflector, and a part of the light will be projected onto the conical reflective surface 12, and then reflected and refracted by the curved unit surface 121 at the same time, thereby improving the overall performance. Reflection, refraction and light mixing effects; in addition, since the reflector 1 is generally installed in the glass lampshade, part of the light projected through the glass lampshade will be reflected by the glass lampshade to the flat reflective surface 11, which can then be reflected by the flat reflective surface. The refraction protruding point 111 on 11 reflects and refracts light again, thereby further improving the optical effect of the entire reflector.

The above descriptions are only preferred embodiments for explaining the utility model, and are not intended to limit the utility model in any form. Changes should still be included within the intended protection scope of the utility model.
