LED light supplement lamp for camera for outdoor service

Abstract

The invention discloses an LED light supplement lamp for a camera for outdoor service. The LED light supplement lamp comprises a lamp body, wherein heat dissipating plates are distributed in the lampbody in the horizontal direction and arranged vertically; a strip-shaped opening arranged in the distribution direction of the heat dissipating plates is formed in the upper top surface of the lamp body; a strip-shaped water outlet arranged in the distribution direction of the heat dissipating plates is formed in the lower bottom surface of the lamp body; the light supplement lamp further comprises a strip-shaped water control tank and a water storage tank, the strip-shaped water control tank is arranged on the upper top surface of the lamp body and covers the strip-shaped opening, the water storage tank is arranged on the upper side of the strip-shaped water control tank, a cylindrical hollow cavity is formed in the strip-shaped water control tank, a regulating and controlling pipe for adjusting on-off of a waterway is rotationally arranged in the cylindrical hollow cavity, and a control box is arranged on one side of the strip-shaped water control tank and used for controlling the regulating and controlling pipe. The LED light supplement lamp has the advantages as follows: by means of rainwater storage, when the light supplement lamp is overheated, the rainwater is introduced into the lamp body to cool the inside of the lamp body rapidly; the rainwater is sprayed to the heat dissipating plates uniformly, so that heat dissipating efficiency is improved, furthermore, the liquidis rapidly evaporated in the heat dissipating process, and corrosion of the rainwater to the heat dissipating plates is reduced.

Description

technical field [0001] The invention relates to a supplementary light, in particular to an LED supplementary light for a monitoring camera. Background technique [0002] At this stage, license plate recognition of moving vehicles at night is mainly assisted by bayonet cameras and electronic police (essentially still bayonet cameras). [0003] However, the above two devices are expensive and complicated to install, and are not suitable for large-scale popularization, and cannot meet the requirements of full coverage of safe city monitoring. Ordinary high-definition surveillance cameras at night to identify moving vehicle license plates mainly rely on constant light sources to fill in the light, but they cannot suppress the strong light of vehicles and solve the phenomenon of screen smearing, and the recognition rate is extremely low. The traditional supplementary light method adopts halogen lamps (above 500W power) and LED white light lamps (above 80W power), both of which h...

Problems solved by technology

[0003] It can be used to supplement the light of the flashlight, but the above two devices are expensive and the installation process is complicated, which is not suitable for large-scale popularization, and cannot meet the requirements of full coverage of safe city monitoring

Ordinary high-definition surveillance cameras at night to identify moving vehicle license plates mainly rely on constant light sources to supplement the light, but they cannot suppress the strong light of vehicles and solve the phenomenon of screen tailing, and the recognition rate is extremely low

The traditional supplementary light method adopts halogen lamps (above 500W power) and LED white light lamps (above 80W power), both of which have the disadvantages of large power consumption and high heat generation. Heat damages bulbs and circuit modules

[0004] Therefore, there is a need for a supplementary light structure that can dissipate heat in time to alleviate the heat dissipation problem of the supplementary light during the period of concentrated heat generation
