LED (Light Emitting Diode) light supplement lens structure for monitoring camera shooting

Abstract

The invention relates to the technical field of LED (Light Emitting Diode) lens structures and discloses an LED (Light Emitting Diode) light supplement lens structure for monitoring camera shooting. The LED light supplement lens structure comprises a mounting plate, a plurality of lenses arranged in the mounting plate as well as LEDs, wherein a mounting structure is arranged in the mounting plate; the plurality of lenses are arranged around the periphery of the mounting structure; one end of each lens is provided with a light emergent surface; the other end of each lens is arranged with a concave cavity provided with an opening; each light emergent surface is exposed at the front end of the mounting plate; each LED comprises a base plate and a light emitting surface; each LED is arranged at the opening of the corresponding cavity, and each light emitting surface is arranged inside the corresponding cavity. Compared with the prior art, the LED light supplement lens structure disclosed by the invention has the advantages that after light emitted by the LED is refracted by an inner concave surface and an inner inclined side wall of each cavity, part of the light is reflected by the side wall of the a corresponding lens and is completely emitted by the corresponding light emergent surface, so the illumination within a certain angle range is formed; since the plurality of lenses are arranged around the outside of the mounting structure, the illumination uniformity during light supplementation is better; in addition, due to the arrangement of the cavities, the light emitting surfaces of the whole LED are completely arranged inside the cavities, the illumination is good, and the utilance is relatively high.

Description

technical field [0001] The invention relates to the technical field of LED lens structures, in particular to an LED supplementary light lens structure for monitoring and photographing. Background technique [0002] In today's life, the technology of using the lens to record information has been widely used in people's daily life. With the increasing popularity of surveillance systems in commercial and civilian use, surveillance cameras (surveillance cameras) are widely used in various fields. For the sake of social security Escort. [0003] For different application fields and environments, different types of surveillance cameras are required, such as in residential buildings, roads, shopping malls and financial offices, etc., and in order to meet the needs of night monitoring and monitoring in some special places, at present, there are also Day and night surveillance cameras have appeared for 24-hour surveillance of some key occasions, and the technology is developing rapi...
