Description

Technical Field

[0001] This invention relates to the field of lighting technology, and more particularly to a lamp. Background Technology

[0002] A lighting fixture typically includes a housing, a light source, a reflector, and a face ring. The housing usually has a light-emitting section, a bottom wall opposite to the light-emitting section, and a cavity connecting the light-emitting section and the bottom wall. Usually, the light source, reflector, and face ring are installed one by one from the light-emitting section of the housing into the cavity of the housing.

[0003] Existing methods for mounting face rings to luminaires include detachable and non-detachable connections. Detachable connections include snap-fit ​​or threaded connections. Non-detachable connections include adhesive fixing or ultrasonic / high-frequency welding for tamper protection. Detachable connections require a lightning bolt tag on the luminaire, which does not comply with current safety regulations and could easily cause accidents. Non-detachable connections require external tools, such as an additional adhesive application process or ultrasonic / high-frequency welding equipment, making face ring installation inconvenient, especially when working at heights.

[0004] In view of this, it is indeed necessary to provide a lighting fixture to solve the above problems. Summary of the Invention

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] It should be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0037] Additionally, it should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0038] Please see Figure 1-8 The image shows a lamp 100 according to an embodiment of the present invention. In this embodiment, the lamp 100 is a spotlight, connected to a track via a connecting rod 60, and can slide on the track to illuminate the desired area. Simultaneously, the connecting rod 60 also allows cables to pass through, protecting the cables and enhancing the aesthetics of the lamp 100. In other embodiments, the lamp 100 may be a downlight or other type of lamp 100; the present invention does not limit this.

[0039] The luminaire 100 includes a housing 10, a light source assembly 20, a mounting bracket 30, a reflector assembly 40, and a face ring 50.

[0040] The housing 10 is made of metal or insulating heat dissipation material and includes a light-emitting part 11, a bottom wall 12 opposite to the light-emitting part 11, and a side wall 13 connecting the light-emitting part 11 and the bottom wall 12. The side wall 13 and the bottom wall 12 enclose a receiving cavity 14. The light source assembly 20, the mounting bracket 30, the reflector assembly 40 and the surface ring 50 are sequentially arranged in the receiving cavity 14.

[0041] The light source assembly 20 is disposed between the mounting bracket 30 and the housing 10. Specifically, the mounting bracket 30 has a mounting position 33 on the side facing the bottom wall 12, and the light source assembly 20 is disposed on this mounting position 33 and emits light toward the light-emitting part 11. Preferably, the light-emitting element of the light source assembly 20 can be an LED light source, specifically, for example, a COB light source. The COB light source is installed in the mounting position 33 of the mounting bracket 30, and the lead wire is inserted into the corresponding lead wire slot.

[0042] Furthermore, a heat dissipation section (not shown) is also provided inside the housing 10, extending from the bottom wall 12 toward the light-emitting section 11. The heat dissipation section is hollow and cylindrical, meaning it is connected to the outer periphery of the bottom wall 12 to increase the outer surface area of ​​the heat sink, thereby transferring some of the heat generated by the light source assembly 20 in the lamp 100 away, thus preventing the light source assembly 20 from being damaged due to excessively high temperature inside the housing 10.

[0043] The mounting bracket 30 is disposed within the receiving cavity 14 of the housing 10, and includes a first end 31 and a second end 32 disposed opposite to each other. The second end 32 is disposed relative to the first end 31 and close to the light-emitting part 11.

[0044] The first end 31 of the mounting bracket 30 is fixedly connected to the housing 10 by fasteners. The inner wall of the housing 10 is provided with positioning ribs 15, and the outer wall of the mounting bracket 30 is provided with a foolproof component 34 corresponding to the positioning ribs 15. The foolproof component 34 includes two parallel foolproof parts 341, with a foolproof groove 342 formed between the two foolproof parts 341. The positioning ribs 15 are inserted into the foolproof groove 342 to achieve a positioning connection between the mounting bracket 30 and the housing 10. Simultaneously, a mounting hole is provided at the first end 31 near the mounting position 33, through which fasteners such as screws are passed to fix the mounting bracket 30 to the housing 10.

[0045] The second end 32 of the mounting bracket 30 is snapped into and self-locked with the face ring 50. The mounting bracket 30 includes a first snap-fit ​​part 36 and a first self-locking part 37, and the face ring 50 is correspondingly provided with a second snap-fit ​​part 51 and a second self-locking part 52. While the first snap-fit ​​part 36 and the second snap-fit ​​part 51 are snapped into each other, the first self-locking part 37 and the second self-locking part 52 abut against each other and lock themselves in place. This design allows the face ring 50 to be easily and conveniently installed on the mounting bracket 30 without the aid of external tools, which meets safety regulations, avoids the problem of electric shock caused by exposed electrical components, eliminates the need for lightning protection stickers, saves labor and equipment, and is especially convenient for high-altitude operations.

[0046] Please see Figure 3-8 As shown, in this embodiment, the first latching part 36 and the first self-locking part 37 are back-to-back, and the second latching part 51 is disposed adjacent to the second self-locking part 52 with a first gap 501 between them. When the face ring 50 is mounted on the mounting bracket 30, the first latching part 36 and the first self-locking part 37 are inserted into the first gap 501, and the first latching part 36 is disposed toward the second latching part 37 to form a latching connection, while the first self-locking part 37 is disposed toward the second self-locking part to form an abutment self-lock.

[0047] Specifically, the mounting bracket 30 also includes a peripheral wall 35, and a first latching portion 36 is disposed on the outer side of the peripheral wall 35. The first latching portion 36 includes a connecting portion 361 and a first hook 362 facing away from the peripheral wall 35. One end of the connecting portion 361 is connected to the outer side of the peripheral wall 35, and the other end of the connecting portion 361 is connected to the first hook 362. The first hook 362 is wedge-shaped, and its cross-sectional area gradually increases from the side away from the peripheral wall 35 to the side closer to the peripheral wall 35. That is, the first hook 362 protrudes in the direction away from the peripheral wall 35, and the first holding surface 3621 of the first hook 362 faces upward. That is, the surface of the first hook 362 facing away from the housing 10 is inclined towards the housing 10 to form a first inclined surface 3622, so as to facilitate its latching connection with the second latching portion 51 on the face ring 50. The first inclined surface 3622 on the first hook 362 also guides the latching connection between the first hook 362 and the second latching portion 51.

[0048] A second gap 372 exists between the first latching part 36 and the peripheral wall 35. A support rib 371 is provided on the side of the first latching part 36 facing the second gap 372. The first self-locking part 37 is formed by the support rib 371, the second gap 372, and the peripheral wall 35. That is, the peripheral wall 35, the second gap 372, and the support rib 371 together form the first self-locking part 37, and the first self-locking part 37 is arranged opposite to the first latching part 36. The first latching part 36 is arranged outward relative to the first self-locking part 37. Correspondingly, the face ring 50 has a second latching part 51 and a second self-locking part 52 arranged adjacent to each other. The second self-locking part 52 is arranged inward relative to the second latching part 51, that is, the second self-locking part 52 is located inside the second latching part 51, and the second self-locking part 52 extends and protrudes in the direction of the mounting bracket 30 to form an annular self-locking rib. The second self-locking part 52 (annular self-locking rib) is inserted into the second gap 372 and is limited by the supporting rib 371 and the peripheral wall 35. When the mounting bracket 30 and the face ring 50 are connected by the first snap-fit ​​part 36 and the second snap-fit ​​part 51, the first self-locking part 37 and the second self-locking part 52 abut against each other and lock themselves. Through the oppositely arranged first snap-fit ​​part 36 and first self-locking part 37, and the adjacently arranged second snap-fit ​​part 51 and second self-locking part 52, the non-detachable connection of the mounting bracket 30 and the face ring 50 can be achieved in one installation, saving time and effort. Of course, in other embodiments, the first snap-fit ​​part 36 can also be arranged relatively inward compared to the first self-locking part 37, and the second snap-fit ​​part 51 should also be arranged relatively inward compared to the second self-locking part 52. The present invention does not limit this.

[0049] The connecting portion 361 is inverted L-shaped, including a horizontal portion 3611 and a vertical portion 3612. The horizontal portion 3611 is connected to the outer surface of the peripheral wall 35, and the vertical portion 3612 is connected to the first hook 362. A second gap 372 is formed between the vertical portion 3612 and the peripheral wall 35. A support rib 371 is disposed on the side of the vertical portion 3612 facing the peripheral wall 35 and close to the horizontal portion 3611. The support rib 371 and the second gap 372 cooperate to form a first self-locking portion 37. A guide slope 3711 is formed between the end of the support rib 371 near the first hook 362 and the connecting portion 361. The support rib 371 has a fixed end and a free end. The fixed end is connected to the peripheral wall 35, and the free end is connected to the first latching portion 361 by the guide slope 3711. The distance from any point on the guide slope 3711 to the vertical portion 3612 in the connecting portion 361 is positively correlated with the cross-sectional area of ​​that point. This facilitates guiding the second self-locking part 52 of the face ring 50 into the first self-locking part 37, while the support rib 371 also enables the first snap-fit ​​part 36 to be supported outwards without deforming inwards, thereby improving the stability of the snap-fit ​​connection.

[0050] The support rib 371 is disposed on the side of the connecting portion 361 facing the peripheral wall 35, that is, the support rib 371 is disposed within the second gap 372, dividing the second gap 372 into a first portion away from the first hook 362 and a second portion close to the first hook 362. In the direction perpendicular to the peripheral wall 35, the width of the second portion is greater than the width of the first portion, and the width of the first hook 362 is greater than the distance between the support rib 371 and the second self-locking portion 52 but less than the distance between the connecting portion 361 and the second self-locking portion 52. With this configuration, when the face ring 50 approaches the mounting bracket 30, the second self-locking part 52 on the face ring 50 is inserted into the first part of the second gap 372 and is limited by the support rib 371 and the peripheral wall 35 in the first self-locking part 37, forming a limiting self-lock. At the same time, since the width of the first hook 362 is less than the distance between the connecting part 361 and the second self-locking part 52, the first hook 362 of the first latching part 36 can smoothly pass through the first gap 501 on the face ring 50 and achieve a latching connection with the second latching part 51. When the face ring 50 is snapped together with the mounting bracket 30 (i.e., after the second self-locking part 52 is inserted into the first part of the second gap 372), since the width of the first hook 362 is greater than the distance between the support rib 371 and the second self-locking part 52, when an external force is applied to the connection part 362 exposed on the face ring 50, there is not enough space between the support rib 371 and the second self-locking part 52 for the first hook 362 to deform, so that the face ring 50 can be self-locked and fixed on the mounting bracket 30, thus making the face ring 50 non-removable.

[0051] In this embodiment, four first latching portions 36 are provided, spaced apart on the outer side of the peripheral wall 35, to engage with the second latching portions 51 on the face ring 30. Similarly, four first self-locking portions 37 are also provided, located on the back of the first latching portions 36. When the first latching portions 36 and the second latching portions 51 are matched and connected, a self-locking connection is achieved between the first self-locking portions 37 and the second self-locking portions 52. In other embodiments, the number of first latching portions 36 may be two, three, etc., and this invention is not limited thereto.

[0052] Furthermore, to improve the accuracy of the snap-fit ​​connection between the face ring 50 and the mounting bracket 30, the face ring 50 is provided with a positioning groove 53 corresponding to the position of the foolproof component 34. The foolproof component 34 is inserted into the positioning groove 53 to achieve the positioning connection between the mounting bracket 30 and the face ring 50. That is, in this embodiment, the foolproof groove 342 formed between the two foolproof parts 341 of the foolproof component 34 can be used for positioning connection with the positioning rib 15 of the housing 10, and the two foolproof parts 341 can also be inserted into the positioning groove 53 on the face ring 50 to achieve the positioning connection between the mounting bracket 30 and the face ring 50, which facilitates the installation operation and improves the connection accuracy. This setting allows the positioning connection with the housing 10 and the face ring 50 to be achieved with one foolproof component 34, saving materials. Of course, in other embodiments, the positioning connection between the mounting bracket 30 and the housing 10 and the face ring 50 can also be achieved by two different foolproof components 34, and the present invention does not limit this.

[0053] Specifically, when the face ring 50 is installed onto the lamp 100, since the housing 10 of the lamp 100 is fixedly connected to the mounting bracket 30, the positioning slot 53 of the face ring 50 aligns with the anti-foolproof component 34 of the mounting bracket 30, thus achieving positioning of the face ring 50 and the mounting bracket 30. At this time, the second snap-fit ​​part 51 of the face ring 50 is snapped into place with the first snap-fit ​​part 36 of the mounting bracket 30, and the second self-locking part 52 of the face ring 50 is inserted into the second gap 372 of the mounting bracket 30. The support rib 371 abuts against the second self-locking part 52, preventing the first snap-fit ​​part 36 from deforming inward, thereby achieving self-locking between the face ring 50 and the mounting bracket 30, and preventing the face ring 50 from being disassembled. This design allows the face ring 50 to be easily installed onto the lamp 100 without the need for external tools, while ensuring that the face ring 50 is non-removable, meeting safety requirements, protecting user components from exposure, and saving labor and equipment.

[0054] Please see Figure 8 and combined Figure 3-4 As shown, the face ring 50 also includes an outer peripheral wall 54 surrounding the second self-locking part 52 and a plurality of connecting ribs 59. The outer peripheral wall 54 is spaced apart from the second self-locking part 52, and the connecting ribs 59 are located between the outer peripheral wall 54 and the second self-locking part 52. The two ends of the connecting ribs 59 are respectively connected to the outer peripheral wall 54 and the second self-locking part 52. Furthermore, the space between the outer peripheral wall 54 and the second self-locking part 52 is divided by the plurality of connecting ribs 59 to form a plurality of ventilation holes 55. By providing ventilation holes 55, the convection of air inside and outside the housing 10 is improved, thereby dissipating heat and ventilating the light source assembly 20 and preventing damage to the light source assembly 20. In addition, the weight of the lamp 100 can be reduced, saving costs.

[0055] Both the second latching part 51 and the first gap 501 are disposed within the ventilation hole 55, and the second latching part 51 extends obliquely from the upper surface of the outer peripheral wall 54 into the ventilation hole 55. That is, the second latching part 51 extends from the outer peripheral wall 54 towards the second self-locking part 52, and the surface of the second latching part 51 facing the housing 10 is inclined in a direction away from the housing 10 to form a second inclined surface 512, which cooperates with the first inclined surface 3622 on the first hook 362 to facilitate the latching connection between the first latching part 36 and the second latching part 51. In other words, the second latching part 51 is a second hook that cooperates with the first hook 362, and the second holding surface 511 of the second hook faces downwards, engaging with the first holding surface 3621 of the first hook 362. Placing the second latching part 51 within the ventilation hole 55 effectively covers the latching connection between the face ring 50 and the mounting bracket 30, improving the aesthetics of the lamp 100. Meanwhile, since the ventilation hole 55 is divided into several connecting ribs 59, the presence of the connecting ribs 59 also positions the snap-fit ​​connection between the first snap-fit ​​part 36 and the second snap-fit ​​part 51. In addition, the connecting ribs 59 also limit the snap-fit ​​connection between the first snap-fit ​​part 36 and the second snap-fit ​​part 51 in the circumferential direction, thereby improving the stability of the connection between the mounting bracket 30 and the face ring 50.

[0056] Preferably, the luminaire 100 further includes a reflector 40, which is disposed between the mounting bracket 30 and the face ring 50, and the light source assembly 20 and the reflector 40 are positioned and assembled in the axial direction.

[0057] In this embodiment, the reflective assembly 40 includes reflective paper 41 and reflector 42. The reflective paper 41 is fan-shaped and has two tabs and four slots. The tabs are inserted into the slots to form a cone-shaped reflector that covers the outside of the reflector 42.

[0058] Both the reflector 41 and the reflector 42 have an axis and a light inlet 43 and a light outlet 44 arranged opposite to each other, with the light inlet 43 and the light outlet 44 distributed sequentially along the axis. The light outlet 44 is located near the light emitting part 11. A lens part 45 is provided at the light inlet 43 of the reflector 42, which is provided corresponding to the light source assembly 20 to distribute the light emitted by the light source assembly 20.

[0059] The reflector 42 has an outwardly flanged mounting portion 46 near the light outlet 44, and the face ring 50 has a stepped portion 56 corresponding to the mounting portion 46. The stepped portion 56 is located inside the second self-locking portion 52 so that the mounting portion 46 of the reflector assembly 40 can abut against the stepped portion 56 to support the reflector assembly 40.

[0060] The face ring 50 is also provided with a light-blocking rib 57. The light-blocking rib 57 extends from the side of the step portion 56 away from the second self-locking portion 52 toward the mounting bracket 30. When the reflective component 40 abuts against the step portion 56, the light-blocking rib 57 is located inside the reflective component 40, so that the light-blocking rib 57 can cover the two rings of the light outlet 44 of the reflective component 40, so that the useless light ring generated by the light outlet 44 of the reflective component 40 is not projected into the effective light spot; thus improving the light spot and making it uniform.

[0061] Preferably, the diameter of the end of the face ring 50 near the light-emitting part 11 gradually decreases in the direction away from the light-emitting part 11, forming a stepped shape to form an anti-glare ring 58. The anti-glare ring 58 can prevent glare, thereby improving the lighting comfort of the lamp 100.

[0062] In summary, the lamp 100 of the present invention has a simple structure. The mounting bracket 30 and the face ring 50 are connected by the first snap-fit ​​part 36 and the second snap-fit ​​part 51. At the same time, the mounting bracket 30 and the face ring 50 are self-locked by the first self-locking part 37 and the second self-locking part 52. The self-locking setting is completed when the mounting bracket 30 and the face ring 50 are snap-fitted. This facilitates installation while making the face ring 50 non-removable, thus improving the safety and convenience of the lamp 100.

[0063] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
