Embodiment Construction

[0030] In order to make the technical problems, technical solutions and beneficial effects solved by 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.

[0031] Figure 1-Figure 6 The first embodiment of the ring spotlight disclosed by the present invention is shown, the ring spotlight has a disc-shaped base 1 on which a transparent hollow cylindrical side wall 3 is fixed. The side wall 3 is made of polymethyl methacrylate material through injection molding. The top of the side wall 3 is fixed with an arc-shaped top cover 4, and the base 1, the side wall 3, and the top cover 4 are connected to each other to form a closed cavity. One side of the top cover 4 located in the cavity is a silver-plated metal layer as a reflec...

Abstract

The invention provides a circular-emitting lamp which comprises a base, a light source, a side wall and a top cover, wherein the side wall is fixed on the base; the top cover is fixed on the side wall; the base, the side wall and the top cover form an enclosed cavity together; the light source is arranged on the base in the cavity; one surface of the top cover positioned in the cavity is a reflection surface capable of reflecting light rays; the reflection surface is an indent or convex arc surface; and the side wall is transparent, and scattering dots are distributed on the inner surface and/or the outer surface of the side wall. The emitting region is wide for the circular-emitting lamp, and the light ray uniformity and continuity are high.

Description

technical field [0001] The invention relates to a ring spotlight, in particular to an LED ring spotlight. Background technique [0002] With the continuous development of light-emitting diode (LED) technology and the diversification of light-emitting diode packaging forms, the application of various new types of LED lamps is becoming more and more extensive. Most of the products are LED automotive lamps and traffic lights. It adopts light-emitting diodes with small viewing angle and high light intensity output to form a directional light signal lamp. In order to apply light-emitting diodes to surround-light signal lamp products, in the prior art, light-emitting diodes are usually arranged directly on the circumferential surface of the lamp to present a surround-light effect. However, the light intensity output characteristic curve of the ring spotlight with this structure in its circumferential direction is gear-shaped, thus causing a dark area in the circumferential direct...
