Adaptive learning lamp fusing pir and light sensor

Abstract

The utility model discloses a kind of adaptive learning lamps of fusion PIR and photosensitive sensor, and the learning lamp includes lamp body, and lamp body is composed of base, support structure and lamp head. Pyroelectric infrared sensor and ambient light sensor are provided on lamp head shell, and are respectively used for detecting user presence and detecting ambient light intensity. Lamp head is equipped with lower light source with light direction towards directly below and upper light source with light direction forward and upward. Control module is housed in the inside of support structure, and its microcontroller receives the signal of sensor, and drives upper and lower light source independently by the first, second constant-current output terminal of constant-current driving circuit. The utility model passes through the hardware structure of double sensor collaborative sensing and double light source independent control, solve the problem that existing learning lamp cannot adaptively collaborative control according to user state and environmental change on desktop key illumination and environmental light supplement, improve the use convenience and reduce energy consumption.
