[0040] In existing technologies, to automatically turn on the light when a user appears in a preset area of ​​the mirror light, an infrared photodiode sensor is typically used for detection. This sensor usually consists of an infrared transmitter and an infrared receiver, emitting an infrared beam and detecting whether the light is reflected or blocked by an object. However, due to the limited power of the infrared photodiode sensor itself, holes need to be made in the mirror surface or corresponding structure to ensure accurate reception of reflected light. Therefore, this compromises the integrity of the mirror structure, resulting in an unsightly appearance.

[0041] To solve the above problems, refer to Figure 1 This utility model proposes a laser mirror light, which includes:

[0042] An integral mirror body 10, the integral mirror body 10 including a backlight side and a reflective side;

[0043] The lamp is disposed on the backlight side of the integral mirror body 10;

[0044] A control device 30 is disposed on the backlight side of the integral mirror body 10, and the control device 30 is electrically connected to the lamp.

[0045] A laser detection device 40 is disposed on the backlight side of the integral mirror body 10, and the emitting end of the laser detection device 40 is perpendicular to the backlight side; the laser detection device 40 is electrically connected to the control device 30; the laser detection device 40 is used to detect the target to be tested within a preset range and output a laser detection signal.

[0046] The control device 30 is used to control the lamp to work when it receives the laser detection signal.

[0047] In this embodiment, the integral mirror body 10 includes a glass layer, a metal reflective layer, and a protective layer. It can be understood that the glass layer, metal reflective layer, and protective layer are sequentially bonded together. The glass layer is the foundation of the integral mirror body 10; the outermost layer is a transparent flat glass, which not only provides a smooth, flat surface but also protects the underlying coating. The quality of the glass directly affects the clarity of the mirror image. Adhering closely to the glass layer is the metal reflective layer, typically made of silver or aluminum. This metal layer reflects light, enabling the mirror to form an image. To protect the fragile metal reflective layer from oxidation, scratches, or other damage, a protective material, typically paint or resin, is applied behind the metal layer. This protective material is crucial for ensuring the long-term use of the mirror and maintaining its optical performance. Furthermore, the backlight side is the protective layer, and the reflective side is the glass layer.

[0048] In this embodiment, the luminaire can be a light strip or LED bead of the same size as the overall mirror body 10, and is set on the edge of the backlight side of the overall mirror body 10. It should be noted that, in the area where the luminaire is set, the backlight side of the overall mirror body 10 does not have a corresponding metal reflective layer and protective layer.

[0049] In this embodiment, the control device 30 can be implemented using FPGA (Field Programmable Gate Array), PLC (Programmable Logic Controller), MCU (Microcontroller Unit), DSP (Digital Signal Processor), SOC (System on Chip), etc. The control device 30 is also located on the backlight side of the overall mirror body 10 and electrically connected to the controlled end of the lamp, thereby achieving control of the lamp's operating state while ensuring the integrity of the overall mirror body 10.

[0050] In this embodiment, the laser detection device 40 can be implemented using a laser detection sensor. The laser detection sensor typically includes a laser emitter, optical elements, a photodetector, and signal processing circuitry. The laser emitter emits a highly directional, concentrated laser beam. The laser emitter can be of different types of laser sources, such as semiconductor lasers (LDs) or gas lasers, with the appropriate type selected based on the specific application. The optical elements change the direction of the laser beam, causing it to propagate along a predetermined path. The photodetector captures the reflected light after the laser beam encounters an object and converts it into an electrical signal. Commonly used photodetectors include photodiodes (PDs) and avalanche photodiodes (APDs). Furthermore, the received electrical signal undergoes a series of processing steps, including amplification and filtering, to accurately identify whether an object is approaching and its distance. In this embodiment, the emitting end of the laser detection device 40 is the emitting end of the aforementioned laser emitter. By perpendicularly positioning the emitting end of the laser emitter to the backlight side, detection within a preset range is achieved. The backlight side has a vertically arranged area corresponding to the backlight side, and the backlight side of the overall mirror body 10 does not have a corresponding metal reflective layer and protective layer. The control device 30 receives the laser detection signal output by the laser detection device 40, and then outputs a corresponding control signal to the lamp to control the lamp to operate.

[0051] By employing a laser mirror light, the integrity of the mirror surface can be effectively ensured while enabling user inspection. The laser mirror light includes a main mirror body 10, a lamp, a control device 30, and a laser detection device 40. The laser detection device 40 is located on the backlight side of the main mirror body 10, with its emitting end perpendicular to the backlight side. By setting a light-transmitting area on the backlight side of the main mirror body 10 corresponding to the size of the emitting end of the laser detection device 40, the laser detection device 40 can detect areas within a preset range and output corresponding laser detection signals. This method effectively avoids the problem of needing to drill holes in the mirror surface, which would reduce the aesthetic appeal of the mirror, as is done with infrared photocell sensors.
