Description

Technical Field

[0001] The present invention relates to the technical field of night lights, and in particular to a night light based on human presence sensing. Background Art

[0002] As an artificial lighting device, electric lights can convert electrical energy into light energy, which has greatly promoted the development of human society. In today's society, electric lights are widely used, and night lights are one of them. Night lights are a kind of lamps specially used for lighting when people wake up at night. Compared with general lamps, night lights are lower in brightness and softer, and are not easy to dazzle.

[0003] For example, a Chinese patent with publication number CN112188692A discloses a night light and its brightness intelligent control method. The method includes: real-time detection of indoor ambient brightness; in response to the night light turn-on instruction, obtaining the first duration of the ambient brightness being in a dark environment state; according to the first duration of being in the dark environment state, controlling the illumination brightness when the night light is turned on; the illumination brightness is related to the tolerance of the user's eyes to the light intensity when being in the dark environment state for the first duration.

[0004] Traditional night lights mostly rely on manual switches or light or infrared sensor switches, which have problems such as inconvenient operation and false triggering. With the rapid development of smart home technology, smart lighting products based on human body sensing are gradually favored by the market. However, the existing human body sensing night lights still need to be improved in terms of human body detection accuracy, response speed and intelligence. Summary of the invention

[0005] The purpose of the present invention is to provide a night light based on human presence sensing, which uses advanced microwave radar or infrared pyroelectric sensors to detect the microwave reflection or infrared radiation changes unique to the human body to achieve high-precision recognition of the presence of the human body. The sensor has the advantages of strong anti-interference ability, wide detection range, and fast response speed. Combining multi-dimensional information such as ambient light, human distance, and moving speed, a set of intelligent control algorithms has been developed. The algorithm can dynamically adjust the detection sensitivity and light brightness according to actual conditions to ensure that the light is turned on in time when the human body approaches, and automatically turned off after the human body leaves, while avoiding false triggering and energy waste. At the same time, by optimizing circuit design, selecting low-power components, and adopting intelligent sleep mode and other measures, low-power operation of the night light system is achieved.

When no one is active, the system enters a sleep state to further reduce energy consumption.

[0040] By adopting the above technical solution, when the human presence sensor 4 detects the movement or presence of a human body, a signal is sent to the microcontroller 5; after receiving the signal, the microcontroller 5 determines whether the light needs to be turned on according to the intelligent control algorithm; if the light needs to be turned on, the LED lighting body 3 is controlled to light up, and the brightness is automatically adjusted according to the preset brightness or ambient light; if no human movement is detected within a certain period of time, the light is automatically turned off and enters a low power consumption or sleep state; at the same time, by setting a wireless communication module 7, remote control or linkage with other devices can be achieved through mobile phone APP or voice control.

The lamp cover 2 is installed by the thread, so that the lamp cover 2 can be easily disassembled and assembled.

[0042] Please refer to Figures 1 to 5 As shown, the LED lighting lamp body 3 is installed on the LED circuit board 301, and a mounting hole 302 for installing the LED circuit board 301 is opened on the LED circuit board 301.

By setting the sleeve spring 306, when the sliding clamping rod 30534 is disengaged from the clamping of the LED circuit board 301, the LED circuit board 301 can be popped up under the elastic force of the pop-up sleeve 3061, thereby facilitating the maintenance or replacement of the LED lighting lamp body 3.

[0049] The working principle of the present invention is as follows: when the human presence sensor 4 detects the movement or presence of a human body, a signal is sent to the microcontroller 5; after receiving the signal, the microcontroller 5 determines whether the light needs to be turned on according to the intelligent control algorithm; if the light needs to be turned on, the LED lighting lamp body 3 is controlled to light up, and the brightness is automatically adjusted according to the preset brightness or ambient light; if no human movement is detected within a certain period of time, the light is automatically turned off and enters a low power consumption or sleep state; at the same time, by setting up a wireless communication module 7, remote control or linkage with other devices can be achieved through mobile phone APP or voice control, and when the LED lighting lamp body 3 is damaged, it is only necessary to press the sliding card rod 30534 from both sides and make the sliding card rod 30534 shrink into the installation groove 3051, so that the sliding card rod 30534 can be disengaged from the clamping connection with the LED circuit board 301, so that the LED circuit board 301 can be bounced upward under the elastic force of the sleeve spring 306, thereby facilitating the maintenance or replacement of the LED lighting lamp body 3.
