The invention discloses an LED (Light-Emitting Diode) stroboscopic light supplement lamp. The lamp comprises an LED constant-current driving circuit, an LED module and a control circuit, wherein the LED module is connected with the LED constant-current driving circuit; an output end of the control circuit is connected with a control signal input end of the LED constant-current driving circuit, and an input end of the control circuit is connected with an external control signal; the flashing time of the LED module is controlled by the control circuit; when the trigger time t of the external control signal is not more than a time threshold value t0 of the control circuit, the high level output time of the control circuit is t, and the LED constant-current driving circuit works synchronously with the external control signal; and when the trigger time t of the external control signal is more than the t0, the high level output time of the control circuit is t0, and the working time of the LED constant-current driving circuit is limited at the t0. According to the LED stroboscopic light supplement lamp, the flashing time of the LED module is limited by the control circuit, so that the lamp can be prevented from being excessively bright, the damage to the eyes of a driver is alleviated, and the service life of the lamp is prolonged. The LED stroboscopic light supplement lamp can be used for supplementing light for video shooting and snapshot in intelligent transportation systems of electronic polices, video bayonets and the like.
Description
[technical field] [0001] The invention relates to a road monitoring supplementary light, in particular to an LED strobe supplementary light. [Background technique] [0002] The traditional road monitoring fill light uses xenon flash as the auxiliary light source. The xenon flash lamp is realized by analog circuit, and the charging time is long, which cannot meet the requirements of video fill light. The flashing time of the xenon flash lamp cannot be precisely controlled, the discharge time is long, the brightness is high, and the glare is serious, which not only hurts the driver's eyes but also affects driving safety, and the lamp is also easily damaged by overheating. [Content of the invention] [0003] The technical problem to be solved by the present invention is to provide an LED strobe supplementary light that can prevent the lamp from being too bright and overheated. [0004] The further technical problem to be solved by the present invention is to provide an LED ...
