Abstract
Description
Technical Field
[0001] This utility model relates to the field of lighting technology, and in particular to an infrared sensing module and a lamp. Background Technology
[0002] Traditional sound- and light-controlled delay-time lighting fixtures, which turn on when someone enters and off when they leave, have become mainstream products. While these products achieve energy savings to some extent, they also cause some environmental damage. Due to inherent limitations, the automatic control of these sound- and light-controlled lights requires the assistance of sound, thus contributing to noise pollution and compromising the quiet environment desired by the public. With societal development, these sound- and light-controlled lights are gradually becoming insufficient to meet people's needs. Therefore, infrared sensor lights have been designed to eliminate the need for sound and satisfy people's demands for a high-quality life.
[0003] Infrared sensor lights are lighting fixtures that use infrared sensors to detect human activity. When a person enters the sensing range, the light illuminates. The light turns on when someone approaches and turns off after a delay when the person leaves, achieving automatic control without wasting electricity.
[0004] However, current infrared sensors all have Fresnel lenses covering the sensor, but there is no protection on the outside of the Fresnel lens. This makes the Fresnel lens easy to collide with external objects during production and transportation, thus causing it to be damaged. Utility Model Content
