COB LED VIDEO SURVEILLANCE CAMERA WITH LED LIGHT SOURCE IN COB SYSTEM AND OPERATING METHOD THEREOF

摘要

The present invention relates to a video surveillance camera incorporating an LED light source and a control method thereof in a COB method implemented so that an object can be photographed after illuminating an object by irradiating light using a plurality of LED light sources, and a front surface of the base metal board. A photodiode that is mounted on and detects a brightness level according to ambient brightness; A plurality of infrared LED chips and a plurality of white LED chips are mounted in a chip-on-board (COB) method, and a light source module mounted on the front side of the base metal board: installed on the rear side of the base metal board and the base metal A heat sink that receives and releases heat from the board; An image photographing unit installed through the base metal board and the heat sink and photographing a surrounding image; And installed at the rear end of the image capturing unit, reading whether day or night according to the brightness level detected by the photodiode, and determining the amount of light, driving time, or dimming of the light source module in a PWM (Pulse Width Modulation) method. And a control unit to control the light source module.
