Description

Technical Field

[0001] The utility model belongs to the technical field of lighting, and in particular relates to a lamp holder structure based on infrared sensing. Background Art

[0002] Desk lamps, an indispensable lighting tool in modern life, have made significant progress in recent years in terms of intelligence. With technological advancements, people have placed higher demands on the convenience of desk lamps, expecting them to not only provide adequate lighting but also implement intelligent automatic control during use to improve quality of life and work efficiency. For example, people expect desk lamps to automatically light up when needed, eliminating the need for manual operation and providing greater convenience.

[0003] To meet this demand, several desktop lamps with automatic on / off functions have appeared on the market. Among them, Chinese patent publication CN 2882188Y discloses an infrared light-controlled energy-saving desk lamp. This lamp consists of a base, a lamp holder, a lamp tube, and a power supply circuit. The power supply circuit includes an infrared automatic control switch, a photoresistor automatic control switch, and a photoresistor automatic dimming circuit. A sensor senses the approach of a person and controls the photoresistor automatic control switch on and off. However, while these infrared light-controlled energy-saving desk lamps offer some convenience, in practice, the limited accuracy of infrared sensing often makes it difficult to accurately turn the light on and off when a person sits down or when they leave. This can lead to misjudgments, impacting the user experience. Specifically, existing infrared light-controlled energy-saving desk lamps can misjudgment human presence due to environmental interference or the uncertainty of human movement, potentially turning the light on before the user is fully seated or turning it off before the user has fully left. This inaccurate sensing not only reduces the lamp's practicality but also wastes energy.

[0004] Therefore, in response to the problems existing in the infrared sensing control of existing desktop lamps, there is an urgent need to provide an improved lamp head structure. This structure can realize automatic control of turning on the light when sitting down and turning off the light when leaving the seat based on more accurate infrared sensing technology, thereby meeting modern people's higher demands for convenience and accuracy of desktop lamps. Summary of the Invention

[0005] In response to the problems in the related technology, the utility model proposes a lamp head structure based on infrared sensing to solve the defects of existing desktop lamps in infrared sensing and achieve technical problems such as accurate sensing of turning on the light when sitting down and turning off the light when leaving.

[0006] The technical solution of the utility model is achieved as follows: a lamp holder structure based on infrared sensing includes a lamp holder body, the lamp holder body is provided with an LED light-emitting module, and light is emitted outward through the LED light-emitting module; the middle part of the lamp holder body protrudes along its horizontal direction to form a boss, the upper part of the boss is connected to the supporting lamp pole, and the lower part thereof is provided with a sensing device;

[0007] The sensing device includes a housing, wherein a mounting surface is provided on a side of the housing adjacent to the lamp body, the mounting surface being inclined downward, and an infrared component is provided on the mounting surface; the infrared component includes a small window in the middle and a large window surrounding the small window; a first infrared sensing unit and a second infrared sensing unit are provided on the inner sides of the small window and the large window, respectively; wherein the second infrared sensing units are located on both sides of the first infrared sensing unit, and a distance is provided between the second infrared sensing units on both sides and the first infrared sensing unit; each infrared sensing unit senses through the corresponding window;

[0008] It also includes an electric control module, which is connected to the first infrared sensing unit and the second infrared sensing unit; each infrared sensing unit is used to sense whether a human body is approaching, and the electric control module controls the flickering of the LED light-emitting module accordingly.

[0009] This utility model utilizes a small window and a large window on the infrared component. This combination, along with the placement of the first infrared sensing unit and the flanking secondary infrared sensing units, expands the sensing range of the sensor. The small window and its corresponding first infrared sensing unit are primarily used to accurately identify the main body of a person, while the large window and the flanking secondary infrared sensing units detect a wider area, including when a person is approaching or moving away from the lamp body. This improves the accuracy of human motion recognition, reduces false triggering, and ensures accurate and reliable lighting control.

[0010] As a further improvement of the above solution, the small window includes a base plate portion, the middle bulge of the base plate portion forms a bay window portion; a through slot is provided in the middle of the mounting surface of the shell, the base plate portion abuts against the inner side of the mounting surface, and the bay window portion passes through the through slot and protrudes outward; the outer surface of the mounting surface is concave to form a groove for mounting the large window; a window is provided in the middle of the large window to match the protruding bay window portion. The middle bulge of the base plate portion of the small window forms a bay window portion, which not only enhances the structural strength of the small window, but also cleverly utilizes space, making the installation of the small window in the shell more compact. The bay window portion passes through the through slot of the mounting surface of the shell and protrudes outward. This layout not only saves space in the shell, but also provides a wider field of view for the small window, while ensuring its stable installation on the shell. Secondly, the outer surface of the mounting surface of the shell is concave to form a groove. This design provides a perfect embedding space for the installation of the large window. The shape and size of the groove match the large window, so that the large window can be tightly installed in the groove, which not only ensures the stability of the installation but also improves the overall aesthetics.

[0011] As a further improvement to the above solution, the first and second infrared sensing units are both located on the same circuit board. A protective frame is provided around the first infrared sensing unit, with the outer edge of the protective frame being higher than the outer edge of the first infrared sensing unit. The protective frame provided around the first infrared sensing unit effectively provides physical protection, preventing direct damage to the first infrared sensing unit probe and ensuring device reliability.

[0012] As a further improvement to the above solution, a silicone sleeve is provided over the protective frame of the first infrared sensing unit, which abuts against the inner wall of the bay window. The silicone sleeve has a through-hole at a position corresponding to the probe of the first infrared sensing unit, and the probe of the first infrared sensing unit sequentially passes through the through-hole and the bay window to sense outward. The silicone sleeve effectively prevents rigid collision between the protective frame and the small window, preventing scratches on the small window and ensuring its light-transmitting properties.

[0013] As a further improvement to the above solution, flexible hooks are provided on both sides of the interior of the housing. The circuit board acts on these hooks to deform them, allowing the circuit board to snap into place. The provision of the hooks facilitates installation of the circuit board, ensuring convenient and efficient installation of the first infrared sensing unit, the second infrared sensing unit, and the circuit board.

[0014] As a further improvement to the above solution, the housing is equipped with a strip-shaped light-transmitting hole at the corresponding position of the second infrared sensing unit's probe. The second infrared sensing unit's probe senses outward through this light-transmitting hole and the large window. The arrangement of the strip-shaped light-transmitting hole provides the sensing probe with a larger sensing range, ensuring reliable and accurate sensing.

[0015] As a further improvement of the above solution, the small window and the large window are both made of light-transmitting material, and the outer end surface of the small window is arranged to be flush with the outer end surface of the large window.

[0016] As a further improvement of the above solution, the first infrared sensing unit and the second infrared sensing unit are arranged at the same height, and the second infrared sensing units on both sides are arranged in a mirror-symmetrical manner.

[0017] As a further improvement of the above solution, a plurality of fasteners are provided on the top of the housing of the sensing device, and corresponding slots are provided on the lower part of the boss, and the sensing device is connected to the slots of the boss through the fasteners.

[0018] As a further improvement to the above solution, the angle between the mounting surface of the infrared component and the horizontal plane ranges from 35° to 55°. This appropriately tilted mounting surface allows the infrared component to better capture infrared radiation from moving people, reducing misjudgments caused by angular deviations and further improving the accuracy of light-on and light-off detection.

[0019] Beneficial effects of the utility model:

[0020] (1) The combination of the small window and the large window, as well as the layout of the first infrared sensing unit and the second infrared sensing units on both sides, expands the sensing range of the sensing device. The small window and its corresponding first infrared sensing unit are mainly used to accurately identify the main body of the human body, while the large window and the second infrared sensing units on both sides are used to detect a wider area, including the human body approaching or moving away from the main body of the lamp head. This improves the recognition accuracy of human movements, reduces false triggering, and ensures the accuracy and reliability of lighting control;

[0021] (2) The housing of the sensing device is provided with a downward-sloping mounting surface on the side close to the main body of the lamp holder, so that the infrared component can better capture the infrared radiation when the human body moves. The inclined mounting surface expands the sensing range, especially in low seats or children's use scenarios, and can more accurately identify human movements, reduce misjudgments caused by angle deviation, and further improve the accuracy of turning on the light when sitting down and turning off the light when leaving the seat.

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0046] Example

[0047] like Figures 1-8 As shown, a lamp holder structure based on infrared sensing includes a lamp holder body 1, wherein the lamp holder body 1 is provided with an LED light-emitting module 2, and emits light outwards through the LED light-emitting module 2; specifically, the LED light-emitting module 2 can adopt an LED light bar, and the LED light bar is configured with multiple lamp beads, and emits light outwards through the lamp beads.

[0048] The middle part of the lamp holder body 1 protrudes horizontally to form a boss 3. The upper part of the boss 3 is connected to the supporting lamp pole 4, and the lower part is provided with a sensing device 5.

[0049] The sensing device 5 includes a shell 51. The shell 51 is provided with a mounting surface 52 on a side close to the lamp body 1. The mounting surface 52 is tilted downward, and an infrared component 6 is provided on the mounting surface 52. In this embodiment, the angle between the mounting surface 52 where the infrared component 6 is located and the horizontal plane is in the range of 35° to 55°. Configuring the mounting surface 52 with a suitable tilt angle allows the infrared component 6 to better capture infrared radiation when the human body moves, reduces misjudgments caused by angle deviations, and further improves the accuracy of turning on the light when sitting down and turning off the light when leaving. Specifically, in this embodiment, the preferred angle between the mounting surface 52 and the horizontal plane is 40°, 45°, or 50°.

[0050] The infrared component 6 includes a small window 61 in the middle and a large window 62 arranged around the small window 61; the inner sides of the small window 61 and the large window 62 are correspondingly provided with a first infrared sensing unit 63 and a second infrared sensing unit 64; in this embodiment, the small window 61 and the large window 62 are both made of translucent materials, such as acrylic, glass or translucent plastic materials, to ensure their sensitive and reliable sensing, and the outer end surface of the small window 61 is set flush with the outer end surface of the large window 62, so that it is coordinated and unified with the lamp holder body 1, simple and beautiful.

[0051] The second infrared sensing units 64 are located on either side of the first infrared sensing unit 63, with a distance between them. Each infrared sensing unit senses through its corresponding window. The first and second infrared sensing units 63, 64 are located at the same height, and the second infrared sensing units 64 on both sides are arranged in a mirror-symmetrical manner.

[0052] In this embodiment, there are two first infrared sensing units 63 and two second infrared sensing units 64. The first infrared sensing unit 63 is centrally located and primarily senses the human torso to identify whether the person remains seated. The second infrared sensing units 64 are located on either side of the first infrared sensing unit 63 to detect a wider area, including when a person approaches or moves away from the lamp holder body 1. This improves the accuracy of identifying human motion and reduces false triggering. In a preferred embodiment, the number of the first infrared sensing units 63 and the second infrared sensing units 64 can also be adjusted based on the extended length of the lamp holder body 1 to ensure a wider range of sensing applications.

[0053] It also includes an electric control module (not shown in the figure), which is connected to the first infrared sensing unit 63 and the second infrared sensing unit 64; each infrared sensing unit is used to sense whether a human body is approaching, and the electric control module controls the flickering of the LED light-emitting module 2 accordingly.

[0054] In this embodiment, the small viewing window 61 includes a base plate portion 611, the center of which is raised to form a bay window portion 612. A through slot 521 is provided in the center of the mounting surface 52 of the housing 51. The base plate portion 611 abuts against the inner side of the mounting surface 52, specifically by using a double-sided adhesive J1. The bay window portion 612 extends through the through slot 521 and protrudes outward. The outer surface of the mounting surface 52 is concave to form a groove 522 for mounting the large viewing window 62. A window 621 is provided in the center of the large viewing window 62, which mates with the protruding bay window portion 612. The raised center of the base plate portion 611 of the small viewing window 61 forms the bay window portion 612, which not only enhances the structural strength of the small viewing window 61 but also cleverly utilizes space, making the installation of the small viewing window 61 within the housing 51 more compact. The bay window portion 612 extends through the through-slot 521 of the mounting surface 52 of the housing 51 and protrudes outward. This layout not only saves space within the housing 51 but also provides a wider field of view for the small window 61 while ensuring its secure installation on the housing 51. Secondly, the outer surface of the mounting surface 52 of the housing 51 is concave to form a groove 522. This design provides a perfect insertion space for the large window 62. The shape and size of the groove 522 match the large window 62, allowing it to fit tightly within the groove 522, ensuring both secure installation and enhancing the overall aesthetics.

[0055] In this embodiment, the first infrared sensing unit 63 and the second infrared sensing unit 64 are both mounted on the same circuit board 65. A protective frame 651 surrounds the first infrared sensing unit 63, with its outer edge higher than the outer edge of the first infrared sensing unit 63. The protective frame 651 surrounding the first infrared sensing unit 63 effectively provides physical protection, preventing direct damage to the probe of the first infrared sensing unit 63 and ensuring device reliability. In this embodiment, a silicone sleeve 652 is placed over the protective frame 651 of the first infrared sensing unit 63, which abuts against the inner wall of the bay window 612. The silicone sleeve 652 has through-holes 6521 corresponding to the probe of the first infrared sensing unit 63. The probe of the first infrared sensing unit 63 senses outward through the through-holes 6521 and then through the bay window 612. The silicone sleeve 652 effectively prevents the protective frame 651 from physically colliding with the small window 61, preventing scratches and ensuring the light-transmitting properties of the small window 61.

[0056] In this embodiment, flexible hooks 511 are provided on both sides of the interior of the housing 51. The circuit board 65 acts on the hooks 511 to deform, allowing the circuit board 65 to snap into place. The provision of the hooks 511 facilitates the installation of the circuit board 65, ensuring convenient and efficient installation of the first infrared sensing unit 63, the second infrared sensing unit 64, and the circuit board 65.

[0057] In this embodiment, the housing 51 is provided with a strip-shaped light-transmitting hole 523 at a position corresponding to the probe of the second infrared sensing unit 64. The probe of the second infrared sensing unit 64 senses outward through the light-transmitting hole 523 and the large window 62. The arrangement of the strip-shaped light-transmitting hole 523 provides the sensing probe with a larger sensing range, ensuring reliable and accurate sensing.

[0058] In this embodiment, the top of the housing 51 of the sensing device 5 is provided with multiple fasteners 512, and the lower portion of the boss 3 is provided with corresponding slots 31. The sensing device 5 is connected to the slots 31 of the boss 3 via the fasteners 512. The connection between the fasteners 512 and the slots 31 facilitates disassembly. When the sensing device 5 needs to be repaired or replaced, the operator can easily remove the sensing device 5 from the boss 3 by releasing the fasteners 512 from the slots 31, saving maintenance time and facilitating modular repairs.

[0059] Through the above-mentioned solution of the present invention, in specific applications: the small window 61 and its corresponding first infrared sensing unit 63 are mainly used to accurately identify the main body of the human body, while the large window 62 and the second infrared sensing units 64 on both sides are used to detect a wider area, including the human body approaching or moving away from the lamp body 1. When a person takes a seat, the second infrared sensing unit 64 senses the human body approaching, and the first infrared sensing unit 63 senses the human body's torso, and the lamp body 1 lights up; when the person leaves the seat, the first infrared sensing unit 63 cannot sense the human body's torso, and the second infrared sensing unit 64 senses the person leaving, and the lamp body 1 turns off. The small window 61 and the large window 62 are configured on the infrared component 6. Through the combination of the small window 61 and the large window 62, and the layout of the first infrared sensing unit 63 and the second infrared sensing units 64 on both sides, the sensing range of the sensing device 5 is expanded. This improves the accuracy of human movement recognition, reduces false triggering, and ensures the accuracy and reliability of lighting control.
