[0011] When the light body is in the on state and the sensor in the first position does not detect human information within a first preset time period, the controller controls the power source to move the sensor to the second position; when the sensor in the second position detects human information, the controller controls the light body to remain in the on state, and controls the light body to turn off when no human information is detected.

[0012] In one embodiment, the controller is further configured to control the power source to move the sensor to the first position after the sensor has stayed at the second position for a second preset time.

[0013] In one embodiment, the lamp body includes a main lamp body and a supplementary light body.

[0044] An embodiment of this application provides a lighting device, including a lighting unit and a sensing device: wherein the lighting unit includes a lamp body; the sensing device is disposed on the lighting unit for sensing human information within a target sensing range to control the opening and closing of the lamp body, the sensing device including a sensor 3 and a telescopic component 41, the front end of the telescopic component 41 supporting the sensor 3, and its rear end being connected to a power source to drive the sensor to move between a first position and a second position under the drive of the power source.

[0045] The sensor 3 is configured to sense human body information within a first sensing range when in a first position and to sense human body information within a second sensing range when in a second position. The first sensing range includes a portion of the target sensing range, and the second sensing range includes another portion of the target sensing range that is not covered by the first sensing range.

[0046] This lighting device can be applied to a mirror cabinet. In one embodiment, the mirror cabinet includes a cabinet body 300, a mirror body 200, and a lighting device 100. The mirror body 200 and the lighting device 100 are mounted on the cabinet body 300, with the lighting device 100 located above the mirror body 200. In other embodiments, the lighting device 100 may also be located on the left, right, or lower side of the mirror body 200.

[0047] like Figures 6-11 In the example shown, the mirror 200 is mounted on the front side of the cabinet 300, and the lighting device 100 is located on top of the mirror 200. In this example, the lighting device 100 includes a sensing device and a lighting unit. The lighting unit includes a lamp body and a lamp housing 6. The lamp housing 6 includes a lampshade 61 located in front of the lamp body, and the lamp body is mounted behind the lamp housing 6, forming a cavity with the lamp housing 6. In other embodiments, the lighting unit may also include a lamp housing 6 and a lamp body disposed within the lamp housing 6. The lamp housing 6 is a double-cavity formed by the lampshade 61 and the upper and lower side shells of the lampshade 61 extending to the rear of the lamp body. The telescopic component 41 of the sensing device and the power source 42 are both disposed within the lighting unit. The telescopic component 41 refers to the component that can extend forward and retract backward relative to the lamp body under the action of the power source.

[0048] When the lamp housing 6 is installed in the lighting mounting area of ​​the cabinet 300, the lamp body is positioned further back than the mirror surface of the mirror 200 in the front-to-back direction, and the lamp body is configured to provide light outward from the lampshade 61. The lighting device 100 also includes a wire 7 extending to the rear of the lamp body, which can be connected to a power outlet on the wall mounting surface.

[0049] like Figures 1-5 As shown, a sensing device is installed on the lighting unit to sense human information within the target sensing range for controlling the opening and closing of the lamp. The sensing device also includes a drive mechanism 4 and a sensor 3. The drive mechanism 4 includes a telescopic component 41 and a power source 42. The power source 42 is connected to the telescopic component 41 via a power receiving unit, and the sensor 3 is disposed on the telescopic component 41. In one exemplary embodiment, the telescopic component 41 is a lead screw, and the power source 42 includes a lead screw seat that drives the lead screw to move back and forth. In other embodiments, the telescopic component 41 can also be a rack, sliding rod, etc., and the power source 42 includes a structure that is poweredly connected to the rack or sliding rod.

[0050] A power source 42 is located at the rear of the lamp body. The power receiving part of the telescopic component 41 is connected to the power source 42 at the rear of the lamp body to move back and forth under the drive of the power source 42. A sensor 3 is located at the front end of the telescopic component 41 to move between a first position and a second position in sync with the back and forth movement of the telescopic component 41. The sensor 3 senses human body information within a first sensing range in the first position and senses human body information within a second sensing range in the second position. The first sensing range includes a portion of the target sensing range, and the second sensing range includes the remaining portion of the target sensing range not covered by the first sensing range.

[0051] The lighting device provided in the embodiments of this application can typically be configured with sensor 3 in a first position, where the light is not obstructed and the aesthetics are not affected. When sensor 3 is in a second position, the sensing range covers the area not covered in the first position. Therefore, if no human information is detected in the first position, sensor 3 can be moved to the second position to sense, avoiding the situation where sensor 3 cannot detect human information due to the sensing blind spot when it is in the first position. This solves the problem that when a human is in the sensing blind spot, the sensor fails to detect the human, causing the controller to misjudge and the lamp to turn off prematurely.

[0052] In one example, such as Figures 1-3 As shown, the sensing device is entirely housed inside the lampshade 6 of the lighting unit. Alternatively, the power source 42 can be located outside the lampshade 6 of the lighting unit, while the front end of the telescopic member 41 extends into the lampshade 6. The lamp body includes a main lamp body 1 with a slot 11. The power receiving part of the telescopic member 41 is located behind the main lamp body 1 and connected to the power source 42. The telescopic member 41 is configured to extend through the slot 11 to the front of the main lamp body 1. The second position is located in front of the main lamp body 1 and is farther away from the main lamp body 1 than the first position. That is, the telescopic member 41 reaches the second position when it extends forward to a position farther away from the main lamp body 1.

[0053] In one example, the lamp body also includes a supplementary light body 2, which is fixed together with the sensor 3. When the supplementary light body 2 moves to the first position, it is located in the slot 11. In this way, by setting the supplementary light body 2, supplementary light can be provided to the slot 11, avoiding the problem of uneven light emission caused by the lack of light source at the location of the slot 11.

[0054] Among them, such as Figure 2 and Figure 4 As shown, the main lamp body 1 can be a first plate with lamp beads, the supplementary light body 2 is a second plate with lamp beads, and the sensor 3 is installed on the second plate; wherein, the second plate is configured to fit the slot 11, and in the first position, the second plate is flush with the first plate.

[0055] In one example, the sensor 3 moves to both the first and second positions within the lamp housing 6. The sensor 3 senses human information within the first or second sensing range through the lamp cover 61. The second position is closer to the lamp cover 61 than the first position.

[0056] Figures 8-11 An embodiment of a mirror cabinet is shown, wherein, as shown, Figure 8 and Figure 9 The first sensing range E of the sensor 3 in the lighting device 100 when it is in the first position is shown. Due to the obstruction of the mirror body 200, there is a sensing blind zone in front of the mirror cabinet. When a person walks in front of the mirror cabinet and is in the sensing blind zone, the sensor 3 cannot detect them.

[0057] The lighting fixture on the mirror cabinet has a blind spot. When a person is in the blind spot, the light will turn off if the sensor 3 does not detect a person within a predetermined time. To solve this problem, the sensor 3 can be placed in front of the lamp body, that is, closer to the lampshade 61 than the lamp body, to expand the sensing area. However, placing the sensor 3 in front of the lamp body will block the light emitted by the lamp body to the lampshade 61, resulting in dark areas in the lampshade 61, uneven light emission from the lampshade, and affecting the aesthetics.

[0058] Figure 10 and Figure 11 The second sensing range F is shown when the sensor 3 in the lighting device 100 is in the second position (i.e., the sensor 3 extends to the front of the main lamp body 1). At this time, the second sensing range F includes the part directly in front of the mirror cabinet, and a person walking in front of the mirror cabinet will be sensed.

[0059] In one embodiment, the lighting device further includes a controller 5, which is configured to acquire sensing information from the sensor 3 and control the power source 42 to drive the telescopic component 41 to move and control the opening and closing of the lamp body based on the sensing information. The connection relationship between the controller 5, the sensor 3, the lamp body, and the drive mechanism 4 is as follows: Figure 5 As shown, the controller 5 is electrically connected to the lamp body and the drive mechanism 4 respectively. In an exemplary embodiment, the drive mechanism 4 is configured to include a lead screw and a lead screw seat that drives the lead screw to move back and forth. The lead screw seat is electrically connected to the controller 5 so as to drive the lead screw to move back and forth under the control of the controller 5.

[0060] When the lamp body is in the open state and the sensor 3 in the first position does not detect human information within a first preset time period, the controller 5 controls the power source 42 to move the sensor 3 to the second position; when the sensor 3 in the second position detects human information, the controller 5 controls the lamp body to remain in the open state, and controls the lamp body to turn off when no human information is detected.

[0061] In the embodiments of this application, when sensor 3 is in the first position, if it senses human information, indicating that the human body is within the sensing range, controller 5 determines that someone will control the light to turn on, causing the light to illuminate. When the light is on, if sensor 3 does not sense a human body within a predetermined time (e.g., 30s or 40s), controller 5 moves sensor 3 to the second position to expand the sensing area. If sensor 3 still does not sense human information in the second position, controller 5 determines that the human body has left and controls the light to turn off. If sensor 3 senses human information in the second position, the light remains on.

[0062] In one embodiment, the controller 5 is further configured to control the power source 42 to move the sensor 3 to the first position after the sensor 3 has remained in the second position for a second preset time. That is, when the sensor 3 moves to the second position, it only pauses briefly and returns to the first position after sensing further in the second position. In this way, the lighting device is basically in the normal state of the sensor 3 in the first position during use, and only briefly in the abnormal state of the sensor 3 in the second position, which basically does not affect the appearance and brightness of the lighting device.

[0063] After sensor 3 returns to the first position, the lamp remains on when human presence is detected. When no human presence is detected, controller 5 controls power source 42 to move sensor 3 to the second position. This process of sensing in the second position to determine whether the lamp needs to be kept on or turned off continues.

[0064] Understandably, sensor 3 can also be configured not to automatically return from the second position to the first position. Its return to the first position can be manually controlled. For example, a control switch can be provided so that when sensor 3 moves to the second position, it can be controlled to return to the first position. This allows for flexible control over the time sensor 3 remains in the second position.

[0065] Since the supplementary light body 2 moves between the first and second positions along with the sensor 3, to ensure uniform brightness throughout the entire light body during its movement, in one example, the controller 5 is further configured to gradually decrease the brightness of the supplementary light body 2 as it moves from the first position to the second position, and / or gradually increase the brightness of the supplementary light body 2 as it moves from the second position to the first position. That is, the brightness is adjusted according to the distance between the supplementary light body 2 and the main light body 1 to ensure uniform light emission from the entire light body.

[0066] The following is based on Figures 8-11 and combined Figure 12 The operation of a lighting device in one embodiment is described.

[0067] like Figures 8-9 As shown, in the initial state, sensor 3 in the lighting device 100 is in the first position. When a person walks in front of the mirror cabinet, if sensor 3 in the first position detects human information (information of human presence), the controller 5 controls the lamp to turn on. If no human information is detected, the lamp does not turn on.

[0068] After the light body illuminates for a predetermined period of time, such as 30 seconds, if sensor 3 at the first position can still detect human information, it means the person is still in front of the mirror cabinet, and the light body continues to illuminate. If no human information is detected, the person may be in a blind spot in front of the mirror cabinet (e.g., Figure 8 (As shown in the image), the person may have already left the mirror cabinet. To avoid misjudgment by the controller 5 due to the human body being in the blind spot of the mirror cabinet, the controller 5 controls the sensor 3 to move to a second position for further sensing.

[0069] If sensor 3 at the second position detects human information, meaning the person has not left the mirror cabinet but is only within the sensing blind zone (e.g., Figure 10 If the light remains on and sensor 3 returns to the first position (as shown in the diagram), the light will remain on and sensor 3 will return to the first position. If sensor 3 in the second position does not detect any human presence, it means the person has left the mirror cabinet, so the light will turn off and sensor 3 will return to the first position. Sensor 3 will remain in the second position for only a short time, such as 2 or 3 seconds.

[0070] Sensor 3 returns to the first position and repeats the above steps.

[0071] In one embodiment, the controller 5 includes a processor and a memory. The controller 5 is electrically connected to the drive mechanism 4 and the lamp body. The memory stores a lighting control program. When the processor executes the lighting control program, it controls the drive mechanism 4 and the lamp body to implement the lighting control method. The lighting control method includes:

[0072] When the light body is in the on state and the sensor 3 in the first position does not detect human information within a first preset time period, the sensor 3 is controlled to move to the second position; the sensor in the first position is configured to detect human information within the first sensing range;

[0073] When the sensor 3 in the second position senses human information, it controls the lamp to remain on, and when it does not sense human information, it controls the lamp to turn off. The sensor in the second position is configured to sense human information within the second sensing range.

[0074] In one embodiment, the lighting control method further includes: after the sensor 3 stays at the second position for a second preset time, controlling the sensor 3 to move to the first position.

[0075] In one embodiment, the lamp body includes a main lamp body 1 and a supplementary light body 2, the supplementary light body 2 being configured to move together with the sensor 3 between a first position and a second position;

[0076] In one example, the lighting control method further includes controlling the brightness of the supplementary light body 2 to gradually decrease as the supplementary light body 2 moves from the first position to the second position.

[0077] In one example, the lighting control method further includes: controlling the brightness of the supplementary light body 2 to gradually increase as the supplementary light body 2 moves from the second position to the first position.
