Abstract
Description
Technical Field
[0001] This utility model relates to a lighting device, and more particularly to a night light. Background Technology
[0002] Nightlights are common lighting tools in people's lives, and existing nightlights can generally turn on automatically at night. However, in order to provide necessary lighting for users, the brightness of nightlights cannot be set too low. But when people are trying to fall asleep, high brightness can make it difficult to fall asleep and also waste energy. Nightlights with motion sensors, on the other hand, only turn on when a person approaches, which is inconvenient because people are walking in complete darkness before entering the sensor's range, making them prone to bumping into things.

[0005] The lower cover has a racetrack-shaped cavity, and the PC cover and the upper cover are disposed on the opening surface of the cavity to close the cavity;
[0006] The upper surface of the cover is provided with mounting holes for mounting the Fresnel lens; the driving light source board is fixed in the cavity, and the human body sensing probe is mounted on the driving light source board at the position corresponding to the mounting holes;
[0007] The photodiode is mounted on one end of the driving light source board along the length direction, and the lower cover is provided with a clearance opening for the photodiode to pass through, corresponding to the position of the photodiode.
[0008] The lower surfaces of the PC cover and the top cover extend downwards with multiple connecting posts, and the inner wall of the cavity is provided with slots that correspond one-to-one with the connecting posts.
[0009] The driving light source board is provided with an LED light source at the position corresponding to the PC cover;
[0010] The driving light source board is provided with conductive sockets corresponding to the pins; the lower cover has a relief groove for the pins to extend out.
[0011] In a preferred embodiment, the connecting post and the slot are interference fit.
[0012] In a preferred embodiment: the human body sensing probe is welded to the driving light source board.
[0013] In a preferred embodiment, the photodiode is welded to the driving light source board.
[0014] In a preferred embodiment: the photodiode is used to detect whether the ambient light intensity is lower than a set threshold. If so, the light source board drives the LED light source to light up with a first luminous flux.
[0015] In a preferred embodiment: the human body sensing probe is used to detect whether someone has passed by. If so, and if the ambient light brightness is lower than a set threshold, the light source board drives the LED light source to light up with a second luminous flux; the second luminous flux is greater than the first luminous flux.
[0016] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:
[0017] This invention provides a light-controlled night light with human body sensing. By incorporating a photodiode, the night light automatically illuminates at night, achieving light control. Furthermore, by including a human body sensor, the brightness is further increased when someone passes by at night, providing sufficient illumination. Therefore, it combines energy conservation with providing ample lighting, and even if no one enters the sensing range, the night light remains on, preventing users from having to grope their way through completely dark rooms.
