Reflector unit of efficient low-glare LED lamp and monitoring camera fill-in light

Abstract

The invention relates to a reflector unit of an efficient low-glare LED lamp. An LED light source is arranged at an opening at one end of the reflector; the LED light source is pressed to the upper end surface of a heat dissipator; a convex lens is mounted at an opening at the other end of the reflector; the convex lens extends out from an outer side end surface of a housing mounted on the upper end surface of the heat dissipator; the inner diameter of the opening at one end is smaller than that of the opening at the other end; the inner wall, from the opening at one end to the opening at the other end, of the reflector is an arc-shaped surface which protrudes outward; the end surface, located at the opening at the other end of the reflector, of convex lens is an arc-shaped surface which is sunk toward the convex lens; the surface, located out of the reflector, of the convex lens is an arc-shaped surface which protrudes outward; and a connecting terminal for being connected to the LED light source is mounted on the heat dissipator. According to the reflector unit provided by the invention, the reflector is matched with the convex lens in structure, shape and dimension, thereby forming the shape, the light ray converging enhanced effect of which is the best. The light rays passing through the reflector and the convex lens form uniform conical light columns. The range, the uniformity of ground light rays and the illumination intensity on the ground of the reflector unit can satisfy the actual demands.

Description

technical field [0001] The invention belongs to the technology for improving the structure of a video monitoring supplementary light field , especially a high-efficiency low-glare LED light reflector unit and surveillance camera fill light. Background technique [0002] In road video surveillance, it is mainly composed of video equipment and supplementary light. The supplementary light is used to provide light to ensure the accuracy of the content collected by video equipment. Traditional supplementary lights often use high-pressure sodium lamps and other lamps, but These lamps have high power and consume a lot of electricity. Therefore, after research and development, LED lamps are applied to supplementary lights, and lenses are used to converge and enhance the light and project it out. The overall power is relatively small, but in order to ensure its range and illuminance, these The brightness of LED lamps is high, but it will have a strong dazzling effect on vehicles in ...

[0002] In road video surveillance, it is mainly composed of video equipment and supplementary light. The supplementary light is used to provide light to ensure the accuracy of the content collected by video equipment. Traditional supplementary lights often use high-pressure sodium lamps and other lamps, but These lamps have high power and consume a lot of electricity. Therefore, after research and development, LED lamps are applied to supplementary lights, and lenses are used to converge and enhance the light and project it out. The overall power is relatively small, but in order to ensure its range and illuminance, these The brightness of LED lamps is high, but it will have a strong dazzling effect on vehicles in the direction of illumination, especially at night when the light is dark, drivers who stop at the intersection opposite the fill light will feel the light of the fill light It is very dazzling and has a great impact on the driving operation after the light is changed. For example: when there are pedestrians or non-motorized vehicles crossing the intersection, the driver will be affected by the glare of the supplementary light, and the vision will become smaller and the ability to identify The problem of falling is very prone to traffic accidents, and it will also have a great impact on the drivers of vehicles passing through the intersection normally.
