Abstract

The invention provides a pyroelectric infrared sensor-based lighting control device and system. The device comprises a focusing assembly and at least two pyroelectric infrared sensors, wherein the focusing assembly comprises at least two arc-shaped curved surface structural parts which are sequentially connected and are adjacent to each other, each arc-shaped curved surface structural part is corresponding to a focusing point, the at least two pyroelectric infrared sensors are respectively arranged at each focusing point, the focusing assembly is used for focusing an external infrared signal onto each pyroelectric infrared sensor, and the at least two pyroelectric infrared sensors are used for converting a changing infrared signal to a voltage signal when the changing infrared signal is received by one arbitrary pyroelectric infrared sensor so as to further control a switch-on state of a lighting lamp by the voltage signal. With the device provided by the embodiment of the invention, the inductive sensitivity of the pyroelectric infrared sensors can be effectively improved, and the infrared signal within a relatively large range can be sensed.

Description

technical field [0001] The invention relates to the lighting field, in particular to a lighting control device and system based on a pyroelectric infrared sensor. Background technique [0002] At present, the sensing of human body movements can usually be combined with a pyroelectric infrared sensor (Passive InfraredRay, PIR) and a Fresnel lens. The Fresnel lens has a special optical principle, which can generate An alternating visible zone and blind zone (visible zone is the area where light can pass through the lens, and blind zone is the area where light cannot pass through the lens). When someone moves in front of the lens, the infrared rays emitted by the human body will continuously alternate between the visible area and the blind area, so that the infrared signal received by the pyroelectric infrared sensor is input to the pyroelectric sensor in the form of pulses of strong and weak. The infrared sensor, and then the pyroelectric infrared sensor can sense the moving ...
