Abstract
The invention relates to a small-size dual-identification space occupying sensor which comprises a sensor shell, a Fresnel lens, an infrared pyroelectric element and a microwave sensing element, the Fresnel lens, the infrared pyroelectric element and the microwave sensing element are installed on the sensor shell, and the Fresnel lens is arranged in the middle of the top of the sensor shell. The sensor further comprises a light guide element used for forming a light guide channel between the Fresnel lens and the infrared pyroelectric element, the microwave sensing element is arranged in the middle of the bottom of the sensor shell, and the infrared pyroelectric element is arranged on the edge of the microwave sensing element. Compared with the prior art, the device has the advantages that the size is greatly reduced, and the like.
Description
technical field [0001] The invention relates to a lighting system, in particular to a small-volume dual-identification occupancy sensor. Background technique [0002] In recent years, with the development of the lighting industry, people's requirements for the control of lamps are becoming more and more intelligent. There is a control method that people come to turn on the lights and people go to turn off the lights, which requires effective identification of human body movements. The human body detection sensor becomes the key component of this control function, its performance is directly related to the performance of the lamp, and its volume is directly related to the size and appearance of the product. Scientific research has found that infrared detectors have high detection sensitivity to human bodies moving laterally, but poor detection sensitivity to human bodies moving radially, and are easily affected by ambient temperature; microwave detectors have strong reliabili...
