Intelligent traffic LED flash lamp and circuit thereof

Abstract

The invention relates to an intelligent traffic LED (Light-Emitting Diode) flash lamp and a circuit thereof, aiming to solve the problems that the existing flash lamp causes potential safety hazards to drivers owing to having certain light pollution and that the illumination range of the existing flash lamp has certain limitations. The intelligent traffic LED flash lamp is characterized in that: heat-conducting silicone grease is applied between an aluminum substrate and an LED lamp; the heat-conducting silicone grease is also applied between the aluminum substrate and a lampshade; a radiating fin is formed on the rear portion of the lampshade; a heat-dissipation cavity is formed in the lampshade on the lower portion of the aluminum substrate; a power cord and a respirator are arranged within the heat-dissipation cavity; and symmetrical vent holes are formed on the cavity walls on both sides of the heat-dissipation cavity. The intelligent traffic LED flash lamp effectively solves the problem of light pollution by employing the technology from faint light or medium light to instantaneous shining. The flash lamp is provided with the structure having the external radiating fin and the internal respirator, so that the heat dissipation performance is effectively improved and the illumination range is wide.

Description

technical field [0001] The invention belongs to LED supplementary light equipment used when taking pictures of intelligent traffic checkpoints, electronic police, etc., in particular to an intelligent traffic LED flashlight and a circuit thereof. Background technique [0002] High-definition digital video cameras and cameras are new products applied to the field of intelligent transportation. Its resolution is several times higher than that of traditional analog cameras, but it has relatively high requirements for illumination. It is used in automatic license plate recognition systems, red light electronic police systems and other public security In the monitoring system, in order to enable the camera to capture a clear image of the vehicle, it is necessary to use a flash to fill in the light. [0003] Current flashlights are generally divided into gas flashlights and LED flashlights. The working mode of these flashlights is only to trigger pulsed flashes, that is, from a no...
