Title:
LED LIGHTING DEVICE AND METHOD FOR OPERATING SAME
Document Type and Number:
WIPO Patent Application WO/2023/171928
Kind Code:
A1
Abstract:
An LED lighting device according to the present invention comprises: an LED light-emitting unit; a visible light sensor for measuring the amount of visible light to generate a first measurement value; a near-infrared sensor for measuring the amount of near-infrared light to generate a second measurement value; and a dimming control unit for controlling dimming of the LED light-emitting unit on the basis of the first measurement value and the second measurement value. In the case in which a second measurement conversion value resulting from the conversion of the second measurement value is greater than or equal to a second threshold value, the dimming control unit controls: the LED light-emitting unit to dim down until the first measurement value reaches a first threshold value when the first measurement value is equal to or greater than the first threshold value; and the LED light-emitting unit to dim up until the first measurement value reaches the first threshold value when the first measurement value is less than the first threshold value.
