Description

Technical Field

[0001] This utility model relates to the technical field of home sensor light equipment components, and more specifically, to a sensor light with an adjustable beam shape. Background Technology

[0002] As people's living standards improve, the design of home sensor lights is becoming more and more user-friendly and aesthetically pleasing. Traditional sensor lights generally use human infrared sensors to detect infrared rays of a unique wavelength emitted by a person approaching the body. After being collected by Fresnel lenses, the infrared rays are reflected onto the pyroelectric sensor head, causing a change in the current of the detection module on the main board, which in turn controls the LED beads to turn on and off. In actual application scenarios, when a person gets up at night and passes by the human infrared sensor, the sensor light will automatically turn on to help residents illuminate the surrounding area.

[0003] The existing sensor lights have the following problems: First, the shape of the beam emitted by the existing sensor lights is fixed and cannot meet the needs of different residents, such as displaying specific shape markers in different rooms to help residents guide their movements at night; Second, the beam direction of the existing sensor lights is generally fixed or in a fully illuminated mode, and cannot be flexibly adjusted, making it difficult to help residents guide their way at night. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable beam shape sensor light. This sensor light can individually adjust the beam shape through a light-shielding ring with light-transmitting grooves of different shapes, and can also flexibly change the beam direction, so that the sensor light has a night-time pointing function, improving the user experience of residents.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An adjustable beam shape sensor light includes a top cover, an embedded plate, a bottom sleeve, and a connecting bolt. The lower surface of the top cover is provided with a threaded seat. The surfaces of the embedded plate and the bottom sleeve are both machined with through holes, and the bottom sleeve has a guide support threaded cylinder inside. The connecting bolt passes sequentially through the through hole on the surface of the bottom sleeve, the guide support threaded cylinder inside the bottom sleeve, and the through hole on the surface of the embedded plate, and is screwed into the threaded seat on the lower surface of the top cover to connect the entire sensor light. The upper surface of the embedded plate is provided with a plurality of LED beads arranged in a ring. The plurality of LED beads are surrounded by a diffuser. The diffuser is surrounded by a light-shielding ring. The surface of the light-shielding ring is machined with a plurality of light-transmitting grooves of different shapes at intervals. The light-shielding ring is surrounded by a deflecting baffle.

[0007] As a further optimization of this solution, the light-shielding ring is connected to the bracket seat in the inner hollow area. The bracket seat has a connecting cylinder with a wiring hole at the middle position. The upper end of the connecting cylinder is embedded in the central circular groove on the lower surface of the top plate. A bracket rod is installed around the connecting cylinder through a rotary damper. The bracket rod is fixedly connected to the steering baffle around the light-shielding ring. A pushing protrusion is fixed on the outer side of the steering baffle. The bracket rod is fitted onto the outside of the rotary damper through a collar at the center of the inner end.

[0008] As a further optimization of this solution, the embedded plate is embedded inside the bottom sleeve and limited by the guide support threaded cylinder. A groove is machined at the center of the upper surface of the top cover, and a human infrared sensor and a surface-mount photoresistor are installed inside the groove. The groove is filled with a transparent plastic disc. The human infrared sensor and the surface-mount photoresistor are connected to the ribbon cable interface on the upper surface of the embedded plate through wiring holes.

[0009] As a further optimization of this solution, the lower surface of the top cover is also machined with an annular blind groove, and a steering baffle is rotatably aligned and embedded inside the annular blind groove. The steering baffle is an annular shape that fits the outer side of the light-shielding ring.

[0010] As a further optimization of this solution, a power supply battery is installed on the bottom surface inside the bottom sleeve, and a control button board is embedded in the side surface inside the bottom sleeve. A control motherboard is bonded and fixed to the lower surface of the embedded board, and the control motherboard is connected to the ribbon cable interface, the control button board and the power supply battery through wires respectively.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows:

[0012] In this invention, by installing a diffuser and a light-shielding ring between the existing sensor light top cover and the embedded plate, the diffuser first softens the surrounding LED beads, and then transmits beams of different shapes to the surrounding wall area through several light-transmitting grooves of different shapes at different positions on the surface of the light-shielding ring, so as to meet the personalized needs of different residents. For example, by displaying specific shape marks in different room locations, it can help residents guide their movements at night.

[0013] This invention utilizes a designed steering baffle structure, combined with an internal rotary damper and support rod structure, to allow for adjustment of the steering baffle at different angles. This enables the steering baffle to block part of the light-transmitting groove of the light-shielding ring, thereby flexibly changing the beam direction of the sensor light and giving it a nighttime pointing function, thus improving the user experience for residents.

[0022] To address the issues that existing sensor lights emit fixed beam shapes, failing to meet the diverse needs of residents, such as displaying specific shape markers in different rooms to guide residents at night; and that existing sensor lights generally have fixed beam directions or are fully illuminated from all sides, making it difficult to flexibly adjust them and thus hindering residents' navigation at night.

[0023] like Figures 1 to 5 As shown, this application includes a top cover 1, an embedded plate 3, a bottom sleeve 4, and a connecting bolt 6. The lower surface of the top cover 1 is provided with a threaded seat 26. The surfaces of the embedded plate 3 and the bottom sleeve 4 are both machined with through holes 10, and the bottom sleeve 4 is provided with a guide support threaded cylinder 5. The connecting bolt 6 passes through the through hole 10 on the surface of the bottom sleeve 4, the guide support threaded cylinder 5 inside the bottom sleeve 4, and the through hole 10 on the surface of the embedded plate 3 in sequence and is screwed into the threaded seat 26 on the lower surface of the top cover 1 to connect the entire induction lamp.

[0024] like Figure 2 and Figure 3 As shown, the upper surface of the embedded plate 3 is provided with a number of LED beads 12 arranged around it. The number of LED beads 12 are surrounded by a diffuser 13. The diffuser 13 is surrounded by a light-shielding ring 14. The surface of the light-shielding ring 14 is processed with a number of light-transmitting grooves 19 of different shapes at intervals. The light-shielding ring 14 is surrounded by a turning baffle 15.

[0025] like Figure 3 As shown, the light-shielding ring 14 is connected to the bracket seat 23 in the inner hollow area. The bracket seat 23 has a connecting cylinder 22 with a wiring hole at the middle position. The upper end of the connecting cylinder 22 is embedded in the central circular groove 25 fixed to the lower surface of the top plate 1. A bracket rod 21 is installed on the outer periphery of the connecting cylinder 22 through the rotary damper 20. The bracket rod 21 is fixedly connected to the steering baffle 15 on the outer periphery of the light-shielding ring 14. A pushing protrusion 16 is fixed on the outer side of the steering baffle 15. The bracket rod 21 is fitted onto the outer side of the rotary damper 20 through the collar at the inner center position.

[0026] The embedded plate 3 is embedded inside the bottom sleeve 4 and limited by the guide support threaded cylinder 5. A groove is machined at the center of the upper surface of the top cover 1, and a human infrared sensor 17 and a surface mount photoresistor 18 are installed inside the groove. The groove is filled with a transparent plastic disc 2. The human infrared sensor 17 and the surface mount photoresistor 18 are connected to the ribbon cable interface 11 on the upper surface of the embedded plate 3 through the wiring hole via the line 9.

[0027] like Figure 4 As shown, the lower surface of the top cover 1 is also machined with an annular blind groove 24. The annular blind groove 24 is rotated and aligned to embed a steering baffle 15. The steering baffle 15 is an annular shape that fits the outer side of the light-shielding ring 14.

[0028] like Figure 1 and Figure 5 As shown, a power supply battery 7 is installed on the bottom surface inside the bottom sleeve 4, and a control button board 8 is embedded in the side of the bottom sleeve 4. A control main board 27 is bonded and fixed on the lower surface of the embedded board 3.

[0029] Specifically, such as Figure 6As shown, different specifications of turning baffles 15 can be selected according to the guidance requirements of different site uses. The central angle of the turning baffles 15 of different specifications is different, that is, the number of light-transmitting slots 19 that can be blocked by the turning baffles 15 of different specifications is different. By pushing the protrusion 16 to change the angle of the turning baffles 15, different directions and different numbers of light-transmitting slots 19 can be blocked to achieve angular guidance of the light beam. In actual use, the bottom of the bottom sleeve 4 is glued to the indoor wall or tile with 3M adhesive strip, and the top cover 1 faces outward. Using the human infrared sensor 17 and the surface-mount photoresistor 18, when a person passes by the sensor light in a nighttime environment, the control board 27 lights up all the LED beads. After the light source is diffused by the diffuser 13, it transmits beams of different shapes to the surrounding area of ​​the wall through several light-transmitting grooves 19 of different shapes at different positions on the surface of the light-shielding ring 14, so as to meet the personalized needs of different residents. The shape of the light-transmitting grooves 19 can be selected and processed with different logo patterns as needed for users to choose from. Users can manually change the angle of the deflector 15 by pushing the protrusion 16 to block the light-transmitting grooves 19 in certain directions, so that the light beam of the sensor light has a guiding effect and plays a guiding role at night. For example, all the light-transmitting grooves 19 on one side can be blocked, and the logo pattern transmitted through the light-transmitting grooves 19 on the other side can guide residents to walk to the other side at night to enter the bathroom or kitchen and other areas.
