PWM LED LED lighting lights to which technology for controlling lighting and lighting is applied using PWM cycles and illuminance values of natural light and their control method

摘要

The present invention relates to an LED lighting lamp to which on/off control technology using a PWM cycle and illuminance value of natural light is applied to a lighting fixture installed including an LED module and a ballast, which is electrically connected to the ballast to receive DC power A power supply unit, a control unit connected to the power unit and DC power supply, and storing and performing overall data, PWM control and switching on/off and dimming control of LED lights with DC power supplied from the ballast according to the command of the control unit It relates to an LED lighting lamp to which a point/off control technology using a PWM cycle and natural light illuminance value is applied, characterized in that it comprises a part, (a) the lighting installation step, (b) the illuminance value of the natural light scanned by the illuminance sensor LED lighting to which the PWM cycle and point/off control technology using the illuminance value of natural light are applied It is about the control method. Therefore, the present invention ensures safe activity in a building by turning on/off using the illuminance value of natural light and performing turning on/off and dimming according to the installation location and moving object.
