Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a lighting fixture. Background Technology

[0002] Human body induction lighting is a product designed and developed using new technologies that utilize infrared and pyroelectric principles to sense human activity. When a person or a warm object enters the module's sensing range, the module outputs a high-level pulse signal or a high-level delayed signal. This output pulse or delayed signal can directly drive LED indicator lights or LED lighting fixtures.

[0003] Existing motion-sensing lamps with sensors mounted on the base have significantly different sensing areas when installed on a wall versus under the eaves. Furthermore, when designing linear solutions, the LED driver and LED chips are often placed together on the light source board (each lamp requires an LED driver), and the LED driver needs to be protected with a flame-retardant material of 5VA, resulting in higher lamp costs.
