Problems solved by technology

[0002] The traditional reflective lighting system uses a reflector. In order to collect as much light energy as possible, the size of the reflector should be as large as possible, which also increases the manufacturing cost. The unreflected light will shoot into the sky, causing light pollution, especially It is a healthy environment that causes light intrusion to nearby residential apartments and greatly affects the safety of human settlements.
There are also multi-layer reflective systems. Although they can collect light from a larger angle, the multi-layer reflectors are circular reflectors with the same size structure. This structure does not guide the light to different areas of the ground reasonably. Of course, they also produce No special flare effect

Abstract

The invention relates to the field of optical lighting and discloses a compact multilayer reflecting type lighting system which comprises a light source, a first-layer reflector, a middle-layer reflector and a top-layer reflector. The first-layer reflector and the middle-layer reflector are both of hollow annular structures, and the top-layer reflector is of a round structure; the position relationship between two layers of reflectors meets that alpha bottom is smaller than or equal beta top, the alpha bottom is an included angle between transmitted light at the inner edge of a ring of the reflector on the lower layer and the vertical direction, and the beta top is an included angle between the direction of a connecting line between the outer edge of the reflector on the upper layer and the light source and the vertical direction; and reflected light can fall out of the reflector on the lower layer after light is reflected by the top-layer reflector. According to the compact multilayer reflecting type lighting system, the reflectors of a multilayer structure are utilized to collect light energy at the maximum angle and transmit the light energy to a target area. Meanwhile, the radial sizes of the reflectors are small, and the reflectors can be conveniently integrated into lamp poles and wall lamps. The layers of reflectors respectively correspond to light at different emitting angles, and the layers of reflectors can be independently and optically designed to achieve different light spot effects in corresponding areas.

Description

technical field [0001] The invention relates to the field of optical lighting, in particular to a compact multi-layer reflective lighting system. Background technique [0002] The traditional reflective lighting system uses a reflector. In order to collect as much light energy as possible, the size of the reflector should be as large as possible, which also increases the manufacturing cost. The unreflected light will shoot into the sky, causing light pollution, especially It is a healthy environment that causes light intrusion to nearby residential apartments and greatly affects the safety of human settlements. There are also multi-layer reflective systems. Although they can collect light from a larger angle, the multi-layer reflectors are circular reflectors with the same size structure. This structure does not guide the light to different areas of the ground reasonably. Of course, they also produce There is no special spot effect. Contents of the invention [0003] The...
