Intelligent LED (light-emitting diode) video synchronizing impulse stroboscopic supplemental lighting device

Abstract

The invention discloses an intelligent LED (light-emitting diode) video synchronizing impulse stroboscopic supplemental lighting device. The device is composed of an electronic circuit and a shell, wherein the electronic circuit has the following structure: a 220V alternating current is connected with a 24V switching power supply and a synchronization generator, the 24V switching power supply is connected with an LED lamp matrix and a +12V power supply circuit, the +12V power supply circuit is connected with a +5V power supply circuit, a light ray detection circuit is connected with a signal processing circuit, a signal input circuit is connected with the signal processing circuit, the signal processing circuit is connected with a signal output circuit, and the signal output circuit is connected with the LED lamp matrix through an actuator. With the adoption of the device provided by the invention, the phenomena of dazzling, uneven exposure and streaking can be effectively avoided, the synchronous exposure with a frame of a camera and frequency multiplication output of light can be realized, and the problem that the color of the red light in an image shot by a monitoring camera changes from red to yellow during the red light signal of traffic lights is solved.

Description

technical field [0001] The invention belongs to the technical field of outdoor photographic supplementary light equipment, in particular to an intelligent LED video synchronous pulse strobe supplementary light device. Background technique [0002] The resolution of high-definition cameras is several times higher than that of traditional analog cameras, and it has relatively high requirements for illumination, especially in automatic license plate number recognition systems, electronic police systems for running red lights, and other public security and traffic monitoring systems. A clear image puts forward higher requirements for the supplementary lighting equipment; the existing system uses electronic flashlights, halogen lamps and other lighting equipment, and the light source for supplementary light is generally a gas flashlight. The working mode of these flashlights is either always on, Either it is just a pulse flash, that is, it never lights up to flashes instantly. Th...

Problems solved by technology

[0002] The resolution of high-definition cameras is several times higher than that of traditional analog cameras, and it has relatively high requirements for illumination, especially in automatic license plate number recognition systems, electronic police systems for running red lights, and other public security and traffic monitoring systems. A clear image puts forward higher requirements for the supplementary lighting equipment; the existing system uses electronic flashlights, halogen lamps and other lighting equipment, and the light source for supplementary light is generally a gas flashlight. The working mode of these flashlights is either always on, Either it is just a pulse flash, that is, it never lights up to flashes instantly. The light that flashes in this way is very irritating to people's eyes and nerves. It is a kind of light pollution, which poses a certain safety hazard to the driver. Large size, short service life; and LED lights just overcome the above shortcomings, it is a cold light source, less heat, high efficiency, and life can reach 100,000 hours. Simple, small and light, LED strobe fill light technology has been developed rapidly
