Description

Technical Field

[0001] This utility model relates to a lighting device, and more particularly to a night light. Background Technology

[0002] LED lighting is widely used in commercial spaces, workplaces, and residences due to its energy efficiency, long lifespan, and environmental friendliness. However, many LED nightlights currently only have light control functionality; they turn on when the indoor lights are turned off, resulting in energy waste. Utility Model Content

[0003] The main technical problem to be solved by this utility model is to provide a night light with human body sensing and light control. It has light control and human body sensing, and can realize that the night light will only turn on to provide auxiliary lighting when someone passes by after dark, thus saving energy.

[0004] To solve the above-mentioned technical problems, this utility model provides a night light with human body sensing and light control, including: an upper cover, a light guide cover, a bottom cover, and a light-emitting component;

[0005] The upper cover, light guide cover, and bottom cover are arranged sequentially along the thickness direction of the night light to clamp the light guide cover between the upper cover and the bottom cover, so as to form a light-emitting surface around the side of the night light in the circumferential direction; the upper cover, light guide cover, and bottom cover define a cavity for accommodating the light-emitting component;

[0006] The light-emitting component includes a driver board, LED beads, photodiodes, and a human body sensing probe; the LED beads are disposed on the side of the driver board and face the light guide cover, and the photodiodes and human body sensing probes are disposed on the upper surface of the driver board and face the upper cover;

[0007] A reflector cup is also provided between the upper cover and the drive plate. The reflector cup has an independent light-inlet cavity corresponding to the photodiode and the human body sensing probe, respectively. A Fresnel lens is provided in the area of ​​the upper cover corresponding to the reflector cup.

[0008] In a preferred embodiment: the bottom cover is provided with a pin, one end of which extends into the cavity and is electrically connected to the drive board, and the other end of which extends out of the bottom cover to form a plug for connection to the mains power.

[0009] In a preferred embodiment: the upper surface of the cover is an arc surface, and the Fresnel lens is fixed on the arc surface by injection molding.

[0010] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0011] This invention provides a night light with human body sensing and light control. By incorporating a photodiode and a human body sensing probe, the night light can only illuminate when both low-light environments and when someone passes by are present. The addition of a reflector cup and a Fresnel lens increases the angle and range of human body sensing, expanding the recognition area and broadening its application. Attached Figure Description

[0015] To make the technical solution and features of this utility model clearer, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific examples. It should be understood that these examples are only for illustrating this utility model and are not intended to limit the scope of this utility model. After reading this utility model, any modifications of this utility model by those skilled in the art in various equivalent forms fall within the scope defined by the appended claims.

[0016] refer to Figure 1-3 This embodiment provides a night light with human body sensing and light control, including: an upper cover 1, a light guide cover 2, a bottom cover 3, and a light-emitting component;

[0017] The upper cover 1, light guide 2, and bottom cover 3 are connected in sequence by bolts along the thickness direction of the night light to clamp the light guide 2 between the upper cover 1 and the bottom cover 3, so as to form a light-emitting surface around the side of the night light in the circumferential direction; the upper cover 1, light guide 2, and bottom cover 3 define a cavity for accommodating the light-emitting component.

[0018] The light-emitting component includes a driver board 5, LED beads 6, photodiode 7, and human body sensing probe 8; the LED beads 6 are disposed on the side of the driver board 5 and face the light guide cover 2, and the photodiode 7 and human body sensing probe 8 are disposed on the upper surface of the driver board 5 and face the upper cover 1.

[0019] A reflector cup 9 is also provided between the upper cover 1 and the drive plate 5. The reflector cup 9 has an independent light-entry cavity corresponding to the photodiode 7 and the human body sensing probe 8 respectively. A Fresnel lens 10 is provided in the area of ​​the upper cover 1 corresponding to the reflector cup.

[0020] The aforementioned night light with human body sensing and light control, by incorporating a photodiode 7 and a human body sensing probe 8, can illuminate only when both low-light environments and when someone passes by. Adding a reflector cup 9 and a Fresnel lens 10 increases the angle and range of human body sensing, expanding the recognition area and broadening its application.

[0021] Furthermore, in this embodiment, the bottom cover 3 is provided with a pin 11. One end of the pin 11 extends into the cavity and is electrically connected to the drive board 5, while the other end of the pin 11 extends out of the bottom cover 3 to form a plug for connection to the mains power. To further enhance the function of the Fresnel lens 10, in this embodiment, the upper surface of the upper cover 1 is an arc surface, and the Fresnel lens 10 is fixed to the arc surface by injection molding.

[0022] The above is only one specific embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
