Title:
LED CALIBRATION LIGHT SOURCE FOR SENSORS, AND LAMP
Document Type and Number:
WIPO Patent Application WO/2020/259094
Kind Code:
A1
Abstract:
An LED calibration light source for sensors, and a lamp. The LED calibration light source comprises an ultraviolet light unit, a visible light unit, an infrared light unit, and a control unit; the optical spectrum of the ultraviolet light unit is continuous in the range of 380 to 420 nm; the optical spectrum of the visible light unit is continuous in the range of 420 to 780 nm; the optical spectrum of the infrared light unit is continuous in the range of 780 to 1000 nm; the control unit controls the ultraviolet light unit, the visible light unit, and the infrared light unit to emit light, such that optical spectrum of the LED calibration light source is continuous in the range of 380 to 1000 nm. The optical spectrum of the LED calibration light source in the range of 380 to 1000 nm has a similar shape to the optical spectrum of the sunlight having the identical color temperature. The LED calibration light source can replace existing halogen lamp light sources for sensors, and has good application prospect for sensors.
