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

Embodiment Construction
[0025] The following description serves to disclose the present invention to enable those skilled in the art to carry out the present invention. The preferred embodiments described below are only examples, and those skilled in the art can devise other obvious variations.
[0026] Such as Figures 1 to 10 The shown LED supplementary light for outdoor surveillance cameras includes a lamp body 12, an LED lamp bead 18 and a condenser cover 11 are arranged at the front end of the lamp body 12, and heat dissipation lamps are arranged in the lamp body 12 along the horizontal direction. Plate 13, the heat dissipation plate 13 is vertically arranged, the upper part is in contact with the upper surface of the inner side of the lamp body 12, the lower part is in contact with the lower surface of the inner side of the lamp body 12, and one side is connected to the front end of the lamp body to guide heat. The surface has strip-shaped openings arranged along the arrangement direction of t...

The invention discloses an LED supplementary light for an outdoor monitoring camera, which comprises a lamp body. Radiating plates are arranged in the lamp body along the horizontal direction, and the cooling plates are arranged vertically. Strip-shaped opening, the lower bottom surface has strip-shaped water outlets arranged along the direction of heat sink arrangement, the supplementary light also includes a strip-shaped water control tank arranged on the top surface of the lamp body and covering the strip-shaped opening, and a strip-shaped water control tank arranged on the strip-shaped control The water storage tank on the upper side of the water tank has a cylindrical cavity inside the strip-shaped water control tank, and a control tube for adjusting the on-off of the water circuit is rotatably installed in the cylindrical cavity, and a control box is set on one side of the strip-shaped water control tank to control Control tube. The advantages of the present invention are: by storing rainwater, when the supplementary light is overheated, the rainwater is passed into the lamp body to quickly cool down the inside of the lamp body; The medium evaporates the liquid quickly, reducing the corrosion of the rainwater on the cooling plate.
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...
