Description

Technical Field

[0001] This utility model relates to the field of lighting fixtures, and more particularly to lighting fixtures and sensor components. Background Technology

[0002] Outdoor lighting fixtures are typically used with light sensors, which consist of a sensor head and pins, with the photosensitive surface on the front of the sensor head. When the sensor head detects that the ambient light brightness has reached a certain level, the light fixture will turn on or off accordingly.

[0003] However, existing light sensors have excessively large photosensitive areas, resulting in overly high sensitivity in certain environments when used in lighting fixtures. Therefore, the photosensitive area of ​​the light sensor needs to be adjusted according to the usage environment. In existing technologies, a light-shielding film is attached to the light sensor, but the light-shielding consistency among multiple lamps is poor. The actual light-receiving areas of the light sensors in multiple lamps are not the same, ultimately leading to large deviations in the light-sensing activation time of multiple lamps. This makes it difficult to achieve unified lighting or extinguishing of multiple lamps, affecting the performance. Utility Model Content

[0004] In view of this, the present invention provides a lamp and a sensor assembly to solve the problem of inconsistent light-receiving area of ​​light sensors in the prior art.

[0005] To achieve one, some, or all of the above objectives, or other objectives, this utility model proposes:

[0006] A lighting fixture, including a sensor assembly, which includes a light shield and a light sensor. The light sensor includes a sensing head, one side of which is a photosensitive surface. The light shield has a light-transmitting hole, which partially covers the photosensitive surface, and the photosensitive surface senses ambient light through the light-transmitting hole.

[0007] In some embodiments, the light-shielding member includes a mounting portion and a light-shielding portion. The mounting portion forms a mounting groove, and a first end of the mounting portion is provided with an inlet communicating with the mounting groove. The light-shielding portion is provided at a second end of the mounting portion and extends toward the middle of the mounting groove. The sensing head of the light sensor enters the mounting groove from the inlet. The light-shielding portion partially covers the photosensitive surface and forms a light-transmitting hole.

[0008] In some embodiments, the light-shielding portion is arranged in a ring shape.

[0009] In some embodiments, the light-shielding part and the mounting part are integrally formed.

[0010] In some embodiments, the luminaire further includes a fixing member that is detachably connected to a light shield, and the light shield and the fixing member together fix the light sensor.

[0011] In some embodiments, two spaced-apart clearance slots are provided on the fixing member, the clearance slots passing through the fixing member, and the light sensor also includes two pins, the two clearance slots being used to accommodate the two pins of the light sensor respectively.

[0012] In some embodiments, a mounting groove is formed on the light-shielding member, a light-transmitting hole is connected to the mounting groove, the sensor head of the sensor is placed in the mounting groove, and the fixing member is embedded in the mounting groove in an interference fit and abuts against the sensor head.

[0013] In some embodiments, the light-shielding member includes a mounting portion and at least one rib formed on the outer wall of the mounting portion, the mounting portion being sleeved on the outside of the sensor head, and the rib extending along the length direction of the mounting portion.

[0014] In some embodiments, the light-shielding member includes a mounting portion and an outer flange protruding from the outer wall of the mounting portion, the mounting portion being sleeved on the outside of the sensor head.

[0015] This utility model also provides a sensor assembly, which includes a light shield and a light sensor. The light sensor includes a sensing head, one side of which is a photosensitive surface. The light shield has a light-transmitting hole, which partially covers the photosensitive surface and allows part of the photosensitive surface to sense ambient light through the light-transmitting hole.

[0016] Implementing the embodiments of this utility model will have the following beneficial effects:

[0017] After adopting the above-mentioned lamps and sensor components, the light sensor is fixed on the lamp and partially blocked by the light shield. Since the light-transmitting holes on each light shield are designed with a uniform diameter, the actual light-receiving area of ​​the light sensors installed on multiple lamps using this sensor component is basically the same, and the amount of ambient light they are sensitive to tends to be consistent, thus making the light-sensing activation of multiple lamps more synchronized.

[0034] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0035] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0036] See appendix Figures 1 to 9 This utility model proposes a sensor assembly and a lamp fixture equipped with the sensor assembly. The lamp fixture includes a lamp housing 1002, a circuit board and a light-emitting unit located within the lamp housing 1002, and a mounting hole 10021 for mounting a light sensor 1001. The sensor assembly includes a light-shielding member 10 and a light sensor 1001. The light sensor 1001 has a sensing head 10011 and two pins 10012 connected to the sensing head 10011. One side of the sensing head 10011 is a photosensitive surface 10013, and the pins 10012 are electrically connected to the circuit board. The sensing head 10011 of the light sensor 1001 and the light shield 10 are in a relatively fixed positional relationship. For example, the light shield 10 is fixedly installed on the sensing head 1001. A light-transmitting hole 102 is opened on the light shield 10. The light-transmitting hole 102 and the photosensitive surface 10013 of the sensing head 10011 are arranged corresponding to each other, so that the light shield 10 partially covers the photosensitive surface 10013. The photosensitive surface 10013 of the sensing head 10011 receives / senses ambient light through the light-transmitting hole 102.

[0037] After the light-shielding component 10 and the light sensor 1001 are installed, the light-shielding component 10 is placed into the mounting hole 10021 of the lamp housing 1002. At this time, the light-transmitting hole 102 coincides with or is on the same plane as the mounting hole 10021, so that the photosensitive surface 10013 of the sensor head 10011 is exposed from the mounting hole 10021, as shown in the attached figure. Figure 1 and 9 As shown. In other embodiments, the light-shielding member 10 may be integrally formed with the lamp housing 1002.

[0038] The light-shielding member 10 can be made of rigid or tough materials and is not easily deformed. The light-shielding member 10 has a first state when the light sensor 1001 is not installed and a second state after the light sensor 1001 is installed. The aperture of the light-transmitting hole 102 remains consistent in both the first and second states. Furthermore, when the light-shielding member 10 is fixed on the sensing head 10011, the relative positions of the photosensitive surface 10013 and the light-transmitting hole 102 are fixed and uniform.

[0039] The user can use the light shield 10 to fix the light sensor 1001 to the lamp housing 1002. The size of the light-transmitting hole 102 on the light shield 10 does not change due to the installation of the light sensor 1001, that is, the area of ​​the photosensitive surface 10013 exposed through the light-transmitting hole 102 is a fixed value. Therefore, multiple lamps using this sensor assembly can have light sensors 1001 with basically the same actual light-receiving area, and the amount of ambient light they are sensitive to tends to be consistent, thus making the light-sensing activation of multiple lamps more synchronized.

[0040] Regarding the structural arrangement of the light-shielding member 10, in some embodiments, as shown in the appendix... Figure 3 , 4 As shown in Figures 5 and 6, the light-shielding member 10 includes a mounting portion 11 and a light-shielding portion 12 formed at the end of the mounting portion 11. A mounting groove 101 is formed in the hollow area inside the mounting portion 11. An inlet 1111 communicating with the mounting groove 101 is provided at the first end 111 of the mounting portion 11. The light-shielding portion 12 is provided at the second end 112 of the mounting portion 11 and extends towards the center of the mounting groove 101. The sensing head 10011 of the light sensor 1001 enters the mounting groove 101 from the inlet 1111, and the light-shielding portion 12 abuts against the sensing head 10011 of the light sensor 1001 to prevent the light sensor 1001 from falling out of the light-transmitting hole 102. Furthermore, the light-shielding portion 12 partially covers the photosensitive surface 10013, and the light-shielding portion 12 surrounds the aforementioned light-transmitting hole 102.

[0041] Furthermore, depending on the type of light sensor 1001 and the different usage requirements, the width of the light-shielding part 12 can be designed accordingly. The wider the light-shielding part 12 is, the smaller the light-sensing area of ​​the light sensor 1001 will be, and vice versa.

[0042] In this embodiment, since the shape and size of the light-shielding member 10 of each sensor component are the same, and the shape and size of the light-shielding part 12 on each light-shielding member 10 are also the same, the light-sensing area of ​​each lamp equipped with such a sensor component is also the same, and multiple lamps can be turned on or off at the same time.

[0043] Regarding the light-shielding portion 12, in some embodiments, as shown in the attached... Figure 4 As shown, only one light-shielding part 12 is provided and is distributed in a ring on the second end 112 of the mounting part 11, and the inner area of ​​the ring-shaped light-shielding part 12 constitutes the aforementioned light-transmitting hole 102.

[0044] Regarding the light-shielding part 12, in other embodiments, see the attached diagram. Figure 6 As shown, multiple light-shielding parts 12 can be provided, and the multiple light-shielding parts 12 are distributed in a ring at intervals around the mounting groove 101.

[0045] Regarding the structural design of the light-shielding component 10, see attached... Figure 7 As shown, in other embodiments, the mounting part 11 may be a hollow design with holes to connect to the mounting groove 101, or the mounting part 11 may be formed by a plurality of rods 113, with a ring-shaped light-shielding part 12 connecting all the rods 113.

[0046] In some embodiments, see Appendix Figure 1 and 2 The sensor assembly also includes a fixing member 20, which is detachably connected to the mounting groove 101. The light-shielding member 10 and the fixing member 20 together fix the light sensor 1001. Specifically, when installing the light sensor 1001, its sensing head 10011 is first placed into the mounting groove 101 and abuts against the light-shielding member 12. Then, the fixing member 20 is inserted into the mounting groove 101 and abuts against the sensing head 10011. Finally, the fixing member 20 and the light-shielding member 12 together clamp the sensing head 10011, so that the sensing head 10011 and the light-shielding member 10 are relatively fixed, thus completing the fixation of the sensing head 10011. Furthermore, to facilitate the installation work, the mounting groove 101 adopts a cylindrical groove design, and the fixing member 20 adopts a cylindrical structure design. The fixing member 20 is embedded into the mounting groove 101 by an interference fit, that is, the inner diameter of the mounting groove 101 is slightly smaller than the outer diameter of the fixing member 20. Of course, to accommodate a specific shape of the light sensor 1001, the shapes of the mounting slot 101 and the fixing member 20 can also be adaptively adjusted, as shown in the attached figure. Figure 8 As shown, the mounting groove 101 has two opposing positioning planes. The fixing member 20 is designed according to the shape of the two positioning planes. At the same time, the use of this non-circular shape of the light sensor 1001 can prevent the light sensor 1001 from rotating relative to the light shield 10.

[0047] In some embodiments, the light-shielding member 10 and the fixing member 20 may be made of rigid materials, such as plastic.

[0048] In other embodiments, the light-shielding member 10 and the fixing member 20 can also be made of flexible materials such as rubber or silicone.

[0049] Since the photosensor 1001 has two pins 10012, to prevent discharge or direct connection between the two pins 10012, in some embodiments, as shown in the attached... Figure 1 , 2As shown in Figure 8, two spaced-apart clearance grooves 201 are provided on the fixing member 20. The clearance grooves 201 extend along the depth direction of the mounting groove 101 and penetrate the fixing member 20. The two clearance grooves 201 are respectively used to accommodate the two pins 10012 of the light sensor 1001. The fixing member 20 is made of insulating material to block the two pins 10012. When the sensing head 10011 of the light sensor 1001 is placed into the mounting groove 101, the two clearance grooves 201 of the fixing member 20 are embedded into the mounting groove 101 corresponding to the positions of the two pins 10012. The pins 10012 of the light sensor 1001 pass through the clearance grooves 201 and are electrically connected to the circuit board inside the lamp.

[0050] In addition, see appendix Figure 2 Since the pins 10012 of the photosensor 1001 are generally longer than the thickness of its sensing head 10011, in some embodiments, the length of the retainer 20 is greater than the depth of the mounting groove 101, while the length of the retainer 20 is slightly shorter than the length of the pins 10012. The two pins 10012 can be insulated from each other and can also protrude beyond the retainer 20 for connection to the circuit board. This arrangement is also to prevent the two pins 10012 from coming close together and causing a short circuit to the sensing head 10011.

[0051] In some embodiments, the light-shielding member 10 is inserted into the mounting hole 10021 with an interference fit. Specifically, the light-shielding member 10 further includes at least one rib 13 formed on the outer wall of the mounting portion 11, with the rib 13 abutting against the inner wall surface of the mounting hole 10021. Further, there are multiple ribs 13, and the ribs 13 extend along the length direction of the mounting portion 11.

[0052] In some embodiments, see Appendix Figure 4 and 9 The light-shielding member 10 also includes an outer abutment 14 protruding from the outer wall of the mounting portion 11. The abutment 14 is flush with the light-shielding portion 12, which is equivalent to the position of the light-transmitting hole 102 being flush with the outer abutment 14. When the mounting portion 11 extends into the mounting hole 10021 and is held in the mounting hole 10021 by the rib 13, the outer abutment 14 is used to abut against the outside of the lamp housing 1002, ensuring that the light-shielding member 10 is at least partially located on the outside of the lamp housing 1002. This prevents the light sensor 1001 from being completely embedded in the mounting hole 10021, and at the same time avoids the light sensor 1001 being affected by the light emitted by the lamp itself.

[0053] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments. The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model. This utility model can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this utility model.
