Description

Technical Field

[0001] This utility model relates to the field of lighting fixtures, and in particular to an embedded spotlight. Background Technology

[0002] Recessed spotlights are lighting fixtures that are installed inside ceilings or walls, featuring directional focusing light characteristics. They reduce space occupation and create a clean and aesthetically pleasing visual effect. Currently, they are mainly used in residential spaces, commercial venues, office environments, as well as hotels and restaurants. They can be used for accent lighting to highlight specific areas or exhibits, or, through combination and matching, can achieve the dual functions of basic lighting and atmosphere creation.

[0003] Currently, when users adjust the lamp head angle according to their lighting needs, the fit between the fixed structure and moving parts of existing recessed spotlights is not precise enough. This can easily lead to the widening of gaps that should fit tightly, creating channels for light leakage. This causes some light to deviate from the preset illumination path and diffuse into non-target areas, weakening the accuracy of the lighting and disrupting the overall visual harmony of the space. Furthermore, the light source of existing recessed spotlights is quite glaring, easily causing visual fatigue and negatively impacting user experience and eye health. In addition, after angle adjustment, the lamp head often wobbles or droops, reducing the stability of the lighting and potentially accelerating wear and tear due to structural loosening over time, shortening the lifespan of the lamp.

[0004] Therefore, there is an urgent need to design an embedded spotlight that can effectively prevent light spillage when adjusting the lamp head angle, ensuring a pure and stray light spot, thereby guaranteeing the directionality of the lighting and the cleanliness of the space; at the same time, it can make the emitted light uniform, soft and comfortable, effectively eliminating the problem of glare, thus balancing the lighting effect and the user's visual health; in addition, it can keep the lamp stable and locked after adjustment, effectively preventing the lamp head from shaking and sagging, and improving the accuracy of projection.

[0027] Currently, when users adjust the lamp head angle according to their lighting needs, the fit between the fixed structure and moving parts of existing recessed spotlights is not precise enough. This can easily lead to the widening of gaps that should fit tightly, creating channels for light leakage. This causes some light to deviate from the preset illumination path and diffuse into non-target areas, weakening the accuracy of the lighting and disrupting the overall visual harmony of the space. Furthermore, the light source of existing recessed spotlights is quite glaring, easily causing visual fatigue and negatively impacting user experience and eye health. In addition, after angle adjustment, the lamp head often wobbles or droops, reducing the stability of the lighting and potentially accelerating wear and tear due to structural loosening over time, shortening the lifespan of the lamp.

[0028] To address the aforementioned issues, this application provides an embedded spotlight that effectively prevents light leakage when adjusting the lamp head angle, ensuring a pure, stray light spot and thus guaranteeing the directionality of the lighting and the cleanliness of the space. Simultaneously, it produces uniform, soft, and comfortable light, effectively eliminating glare and balancing lighting performance with user visual health. Furthermore, it keeps the lamp firmly locked after adjustment, effectively preventing the lamp head from wobbling or sagging, thus improving projection accuracy.

[0029] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings. Example

[0030] Please see Figures 1-7 The recessed spotlight of this application includes a heat sink 1, a light source assembly 2, a lens assembly 3, an adjustment assembly 4, a reflector 5, and a front ring 6. The heat sink 1 is mounted on the lens assembly 3 and is connected to the lens assembly 3. The light source assembly 2 is mounted on the lens assembly 3 and the light emission direction of the light source assembly 2 is downward. The adjustment assembly 4 is located below the lens assembly 3 and has a light-shielding baffle at its bottom end. The reflector 5 is located in the inner cavity of the adjustment assembly 4. The front ring 6 is sleeved on the lower end of the adjustment assembly 4 and can rotate relative to the adjustment assembly 4.

[0031] Specifically, the heat sink 1 is provided with a flow guiding groove 11 and a mounting hole. The power supply passes through the mounting hole and is electrically connected to the light source assembly 2 inside the heat sink 1, thereby supplying power to the light source assembly 2. The flow guiding groove 11 is die-cast and has a wave-like shape, and is open to the air. By setting the flow guiding groove 11 to a wave shape, the contact area between the heat sink 1 and the air can be effectively increased, thereby quickly dissipating the heat generated by the light source assembly 2, and thus maintaining the long-term stable operation of the lamp.

[0032] The lens assembly 3 includes a lens ring 31, a lens 32, and a lens holder 33. The lens 32 is disposed on the upper side of the adjustment assembly 4; the lens holder 33 covers the lens 32, and the bottom end of the lens holder 33 is fitted onto the top end of the adjustment assembly 4 and engages with the top end of the adjustment assembly 4; the lens ring 31 covers the lens holder 33 and is located in the inner cavity of the heat sink 1. For example, the lens 32 and the lens holder 33 are generally frustoconical, and the bottom diameter of the lens holder 33 is larger than the bottom diameter of the lens 32. The top end of the lens 32 protrudes slightly from the top end of the lens holder 33. The lens ring 31 is generally inverted frustoconical and covers the lens holder 33. That is, both the lens 32 and the lens holder 33 are located within the lens ring 31, and the top end of the lens ring 31 is much higher than the top end of the lens 32.

[0033] The light source assembly 2 includes a light source 21 and a light source mounting bracket 22. The light source mounting bracket 22 is disposed on the lens 32, and the light source 21 is disposed on the light source mounting bracket 22, facing the reflector 5, and the light source 21 is directly opposite the central through hole 34 of the lens 32. Further, the wall of the central through hole 34 is provided with a honeycomb structure, and the recessed spotlight also includes a frosted light-transmitting mask, which is disposed on the front ring 6 and located inside the front ring 6. When the light source 21 emits light, a portion of the direct light passes directly through the frosted light-transmitting mask and exits, while the other portion of the side-projected light first passes through the lens 32, is refracted multiple times by the honeycomb structure on the lens 32 to the reflector 5, and then reflected back to the lens 32 by the reflector 5. Under the refraction of the lens 32, it passes through the frosted light-transmitting mask and exits. In this process, the light is reflected multiple times by the honeycomb structure lens 32, which makes the light diffuse evenly and reduces glare. The frosted light-transmitting mask causes diffuse scattering of the light after it enters, further destroying the strong light effect of the direct light from the light source 21. The output after triple diffusion and refraction through the lens 32-reflector 5-frosted light-transmitting mask can disrupt the direction of light propagation, reduce the concentration of light intensity, make the light evenly mixed, and make the light in the irradiated area soft, thereby effectively avoiding the glare and discomfort caused by strong direct light and eliminating the problem of eye irritation.

[0034] The adjustment assembly 4 includes a first angle adjustment ring 41 and a second angle adjustment ring 42. The top end of the first angle adjustment ring 41 is engaged with the bottom end of the lens bracket 33 and is located inside the second angle adjustment ring 42. The second angle adjustment ring 42 is disposed inside the front ring 6 and is hinged to the first angle adjustment ring 41. Specifically, the first angle adjustment ring 41 is generally truncated cone-shaped, narrower at the top and wider at the bottom, and the diameter of the top end of the first angle adjustment ring 41 is smaller than the diameter of the bottom end of the lens bracket 33, so that the bottom end of the lens bracket 33 can be fitted onto the top end of the first angle adjustment ring 41; the diameter of the bottom end of the first adjustment ring is smaller than the diameter of the second adjustment ring, so that the first adjustment ring can be placed inside the second adjustment ring.

[0035] For example, the second angle adjustment ring 42 includes a wide diameter end 421, a narrow diameter end 422, and a middle end 423, which are arranged sequentially from bottom to top. The narrow diameter end 422 has an upwardly extending arc-shaped protrusion 424, and the inner surface of the arc-shaped protrusion 424 has teeth 4241. For example, the teeth 4241 are arranged in two rows, symmetrically arranged on the arc-shaped protrusion 424, and extending in the vertical direction. The outer surface of the first angle adjustment ring 41 has a locking point that abuts against the teeth 4241. When vertical adjustment is required, simply hold the first angle adjustment ring 41 or the second angle adjustment ring 42, and then push upwards or pull downwards to allow the first angle adjustment ring 41 and the second angle adjustment ring 42 to move relative to each other. During this process, the locking point moves along the extension direction of the toothed groove 4241. When the force applied by the hand is released, it can be locked within the toothed groove 4241, thereby effectively fixing the relative position between the first angle adjustment ring 41 and the second adjustment ring, ensuring that the lamp can be securely locked after adjustment and effectively preventing the lamp head from shaking or sagging. Furthermore, to facilitate the user's intuitive understanding of the vertical angle adjustment range, the outer surface of the arc-shaped protrusion 424 is provided with angle scale lines 4242, with adjacent angle scale lines 4242 differing by 5 degrees. It should be noted that the vertical adjustment angle of the recessed spotlight provided in this application is 30 degrees.

[0036] The upper inner side of the front ring 6 is provided with straight teeth 61, which are distributed along the circumferential direction of the front ring 6. The middle end 423 is provided with elastic protrusions 4231 that are adapted to the straight teeth 61. When the second angle adjustment ring 42 rotates relative to the front ring 6, the elastic protrusions 4231 move within the straight teeth 61. After the external force is removed, the rotation stops. The elastic protrusions 4231 are locked within the straight teeth 61, thereby effectively fixing the relative position between the second angle adjustment ring 42 and the front ring 6 and preventing inaccurate projection caused by accidental movement of the lamp head.

[0037] Furthermore, to effectively prevent light leakage during adjustment, the light-shielding baffle is disposed between the first angle adjustment ring 41 and the second angle adjustment ring 42. Specifically, the light-shielding baffle is located outside the bottom end of the first angle adjustment ring and inside the bottom end of the second angle adjustment ring 42. Thus, when the first and second adjustment rings move relative to each other, the light-shielding baffle effectively blocks light from leaking out through the gaps. Furthermore, the recessed spotlight also includes a sealing ring disposed at the light-shielding baffle. By providing the light-shielding baffle and the sealing ring, the light can tightly fit the gaps created during adjustment, effectively preventing light leakage.

[0038] Working principle: Up and down angle adjustment: Simply hold the first angle adjustment ring 41 or the second angle adjustment ring 42, and then push it up or pull it down so that the first angle adjustment ring 41 and the second angle adjustment ring 42 can move relative to each other. During this process, the locking point moves along the extension direction of the toothed pattern 4241. When the force applied by the hand is released, it can be locked in the toothed pattern 4241.

[0039] Horizontal rotation adjustment: The second angle adjustment ring 42 is rotated relative to the front ring 6 by external force, and the elastic protrusion 4231 moves in the straight tooth 61. After the external force is removed, the rotation stops and the elastic protrusion 4231 is locked in the straight tooth 61.

[0040] Light path: After the light source 21 emits light, part of the direct light passes directly through the frosted light-transmitting mask and is emitted. The other part of the side-projected light first passes through the lens 32, and is refracted multiple times by the honeycomb structure on the lens 32 to the reflector cup 5. Then it is reflected by the reflector cup 5 back to the lens 32, and is emitted through the frosted light-transmitting mask under the refraction of the lens 32. In this process, the light is reflected multiple times by the honeycomb structure lens 32, so that the light is diffused evenly and glare is reduced. The light is diffused after it is incident by the frosted light-transmitting mask, which further destroys the strong light effect of the direct light from the light source 21. The output after triple diffusion and refraction by the lens 32-reflector cup 5-frosted light-transmitting mask can disrupt the direction of light propagation, reduce the concentration of light intensity, make the light evenly mixed, and make the light in the irradiated area soft.

[0041] In this first embodiment, the embedded spotlight provided by this application includes a heat sink, a light source assembly, a lens assembly, an adjustment assembly, a reflector, and a front ring. By setting a combination of a lens with a honeycomb structure and a frosted light-transmitting mask, and the output after triple refraction of the lens-reflector-frosted light-transmitting mask, the light emitted by the light source can be refracted, reflected, and scattered multiple times, so that the light is evenly diffused and mixed, reducing the light intensity concentration, making the light in the irradiated area soft, reducing glare, and thus effectively avoiding the discomfort caused by strong direct light, effectively eliminating the problem of glare. By providing teeth on the second angle adjustment ring and matching locking points on the first angle adjustment ring, after the lamp is adjusted up and down, it can be locked in the teeth by the locking points, thereby effectively fixing the relative position between the first angle adjustment ring and the second adjustment ring, so that the lamp can be stably locked after adjustment, effectively preventing the lamp head from shaking or sagging. By providing circumferentially distributed straight teeth on the front ring and matching elastic protrusions on the second angle adjustment ring, the relative position between the second angle adjustment ring and the front ring is effectively fixed after horizontal adjustment, preventing inaccurate projection due to accidental movement of the lamp head. By providing a light-shielding baffle and a sealing ring between the first and second angle adjustment rings, the gap between them can be effectively and tightly fitted when adjusting the lamp head angle, preventing light leakage and ensuring that the emitted light is free of stray light, thereby guaranteeing the directionality of the lighting and the cleanliness of the space.
