Embodiment Construction

[0015] 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.

[0016] In the embodiment of the present invention, the inner surface of the reflective cup is designed as a multi-layer prism surface. Along the direction of light emission, the angle between two adjacent prism surface surfaces increases sequentially, so that the center of the light source is located on the central axis of the reflective cup. The light emitted by the light source is reflected by the multi-layer prism table and then mixed in the lighting area, with uniform illumination and high lamp efficiency.

Abstract

The invention is suitable for the lighting field and provides a light reflecting cup, a down lamp and a lighting system, wherein the inner surface of the light reflecting cup is formed by sequentially connecting bottom surfaces and top surfaces of a plurality of layers of prismatic frustum surfaces, in a light emergent direction of light rays, included angles between two adjacent layers of prismatic frustum surfaces are sequentially increased, and the center of a light source is positioned on the central axis line of the light reflecting cup. In the invention, the inner surface of the light reflecting cup is designed into the plurality of layers of prismatic frustum surfaces, in the light emergent direction, the included angles between two adjacent layers of prismatic frustum surfaces are sequentially increased, so that the center of the light source is positioned on the central axis line of the light reflecting cup, the light sent by the light source is mixed at the lighting area after being reflected through the plurality of layers of prismatic frustum surfaces, the illumination is even and the efficiency of the lamp is high.

Description

technical field [0001] The invention belongs to the field of lighting, and in particular relates to a reflective cup, a downlight and a lighting system. Background technique [0002] At present, the inner surface of the reflector cup of the commercially available downlight is a smooth paraboloid, and the illuminance of the light emitted by the light source is not uniform enough after being distributed by the reflector cup, and the efficiency of the lamp is low. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide a reflector cup, aiming at solving the problems of uneven illuminance and low efficiency of lamps after the light distribution of the light source through the existing reflector cup. [0004] The embodiment of the present invention is achieved in this way. A reflective cup, the inner surface of which is composed of multi-layered prism surfaces adjacent to the bottom surface and the top surface in sequence, along ...
