LED light supplementing lamp

Abstract

The invention provides an LED light supplementing lamp, which comprises a front shell, a rear shell, a circuit control module arranged inside the rear shell, and an LED lamp arranged inside the front shell, wherein the front end of the front shell is provided with a reflector cup and a light transmitting window; the rear wall of the front shell and the front wall of the rear shell are connected; the circuit control module and the LED lamp are connected; the side wall of the rear shell is fixedly provided with a leading-out wire pipe; one end of a leading-out wire passes through the leading-out wire pipe and is connected with the circuit control module; the leading-out wire pipe outside the side wall of the rear shell is provided with a locking nut; and the leading-out wire pipe inside the side wall of the rear shell is coated with a sealing adhesive layer. The LED light supplementing lamp is used for improving the vehicle license plate recognition rate in the case of night road monitoring and photographing, and requirements on image definition by intelligent vehicle license plate retrieval are achieved; the light supplementing lamp has a low power and energy conservation and environment protection are realized; the light is uniform and gentle, the sight line of a driver is not influenced, safety driving of the driver can be ensured, and the safety is high; and the rear shell has good sealing effects, influences on the LED lamp by the environment are few, and the service life is long.

Description

technical field [0001] The invention belongs to the field of monitoring camera lighting devices, in particular to an LED supplementary light. Background technique [0002] At present, the license plate recognition of moving vehicles at night is mainly realized by bayonet cameras and electronic police (essentially still bayonet cameras) auxiliary flash lights. However, the above two devices are expensive and the installation process is complicated. They are not suitable for large-scale popularization and cannot achieve safety. Requirements for full coverage of city surveillance. 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 uses halogen lamps (power 500W or more) and LED white light l...

Problems solved by technology

[0005] How to use a low-cost supplementary light method at night, which can not only suppress the strong light of vehicles, but also recognize the license plate of moving vehicles, is a difficult problem in the monitoring industry. There have been no successful cases at home and abroad. application, social needs are more urgent
