Description

Technical Field

[0001] This disclosure relates to the technical field of downlights, and in particular to an anti-glare downlight. Background Technology

[0002] Downlights, as a new type of lighting fixture, are widely used in various lighting applications. However, while providing ample illumination, downlights may also cause glare due to excessive brightness, affecting visual comfort and resulting in a lower user experience.

[0003] Existing technology, such as patent CN221258652U, discloses an LED downlight with an anti-glare structure, which includes a cover, a metal housing with a heat sink, at least one LED light source component placed within the housing, a driving power supply component connected to the housing and the light source component, a light-emitting glass cover snapped into the housing, and a lamp holder. The key feature is that a honeycomb-shaped star-shaped or rhomboid reflector is provided on the outer portion of the housing covering the light source component. This LED downlight design, by incorporating an anti-glare structure centered on reflectors, amplifies the point-like light spots of the LED light into diffused light, improving the uniformity of illumination within the effective lighting range, thereby enhancing the anti-glare effect of the downlight.

[0004] However, the aforementioned downlights are still prone to glare when the light intensity is high, which greatly reduces the user experience. Utility Model Content

[0005] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide an anti-glare downlight with better anti-glare effect.

[0006] The purpose of this disclosure is achieved through the following technical solution:

[0007] An anti-glare downlight is used for installation and fixation inside the main body of a building. The anti-glare downlight includes a lamp body, a light-emitting element, and an anti-glare lamp cover assembly.

[0008] The lamp body has a mounting groove and a light outlet connected to the mounting groove. The light-emitting element is installed in the mounting groove, and the light-emitting end of the light-emitting element is oriented towards the light outlet.

[0009] The anti-glare lampshade assembly includes a lampshade body, a refractive lens, and a floodlight plate. A diffuse reflection layer is formed on the inner peripheral wall of the lampshade body. The lampshade body is located at the light outlet. The refractive lens is installed at one end of the lampshade body adjacent to the light-emitting element. The refractive lens is used to refract light to the inner peripheral wall of the lampshade body. The floodlight plate is installed at one end of the lampshade body away from the light-emitting element, so as to form a diffuse reflection cavity together.

[0010] In one embodiment, the lampshade body is trumpet-shaped, and the cross-sectional area of ​​the end of the lampshade body adjacent to the light-emitting element is smaller than the cross-sectional area of ​​the end of the lampshade body away from the light-emitting element.

[0011] In one embodiment, the refractive lens is detachably mounted on the lampshade body.

[0012] In one embodiment, a first mounting hole is formed at one end of the lampshade body adjacent to the light-emitting element, the first mounting hole has a first threaded connection portion, and a second threaded connection portion is formed on the outer peripheral wall of the refractive lens, the first threaded connection portion being threadedly connected to the second threaded connection portion.

[0013] In one embodiment, the floodlight is detachably mounted on the lampshade body.

[0014] In one embodiment, a second mounting hole is formed at the end of the lampshade body away from the light-emitting element, the second mounting hole forms a third threaded connection portion, and a fourth threaded connection portion is formed on the outer peripheral wall of the floodlight plate, the third threaded connection portion being threadedly connected to the fourth threaded connection portion.

[0015] In one embodiment, the refractive lens is a concave lens.

[0016] In one embodiment, the concave lens is a biconcave lens.

[0017] In one embodiment, the connection position between the lampshade body and the lamp body is adjustable.

[0018] In one embodiment, a fifth threaded connection portion is formed on the outer peripheral wall of the lampshade body, and a sixth threaded connection portion is formed on the inner peripheral wall of the lamp body, wherein the fifth threaded connection portion is threadedly connected to the sixth threaded connection portion.

[0019] In one embodiment, the lamp body includes a lamp barrel and a heat sink, the light outlet is formed at the first end of the lamp barrel, the second end of the lamp barrel is fixedly connected to the heat sink to form the mounting groove together, the fixed end of the light-emitting element is mounted on the side of the heat sink facing the mounting groove, and the light-emitting end of the light-emitting element is positioned facing the light outlet.

[0020] Compared with the prior art, this disclosure has at least the following advantages:

[0021] The aforementioned anti-glare downlight features a diffuse reflection layer formed on the inner wall of the lampshade. The lampshade is located at the light outlet, and a refractive lens is installed at the end of the lampshade near the light-emitting element. The refractive lens refracts light onto the inner wall of the lampshade. A floodlight is installed at the end of the lampshade away from the light-emitting element, together forming a diffuse reflection cavity. When the light-emitting end of the light-emitting element illuminates the refractive lens, the lens refracts the light onto the inner wall of the lampshade. The diffuse reflection layer on the inner wall of the lampshade diffuses the light, reducing its intensity and making it softer and more uniform. When the diffused light shines on the target area through the floodlight, the floodlight further diffuses the light, further reducing its intensity and making the light distribution more uniform and softer. This results in a superior anti-glare effect for the downlight, significantly improving the user experience. Attached Figure Description

[0033] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0034] like Figures 1 to 7As shown, an anti-glare downlight 10 of one embodiment is used for installation and fixation within the main body of a building. The anti-glare downlight 10 includes a lamp body 100, a light-emitting element 200, and an anti-glare lampshade assembly 300. The lamp body 100 has a mounting groove 110 and a light outlet 120 communicating with the mounting groove 110. The light-emitting element 200 is installed in the mounting groove 110, with the light-emitting end of the light-emitting element 200 facing the light outlet 120. The anti-glare lampshade assembly 300 includes a lampshade body 310, a refractive lens 320, and a floodlight 330. A diffuse reflection layer 311 is formed on the inner peripheral wall of the lampshade body 310. The lampshade body 310 is located at the light outlet 120. The refractive lens 320 is installed at one end of the lampshade body 310 adjacent to the light-emitting element 200. The refractive lens 320 is used to refract light onto the inner peripheral wall of the lampshade body 310. The floodlight 330... The 330 is installed at the end of the lampshade body 310 away from the light-emitting element 200 to form a diffuse reflection cavity 340. When the light-emitting end of the light-emitting element 200 shines light onto the refractive lens 320, the refractive lens 320 refracts the light onto the inner peripheral wall of the lampshade body 310. The light is then diffused by the diffuse reflection layer 311 on the inner peripheral wall of the lampshade body 310 to reduce the intensity of the light and make the light softer and more uniform. When the light after being diffused by the diffuse reflection layer 311 shines on the target area through the floodlight plate 330, the floodlight plate 330 can diffuse the light, further reducing the intensity of the light and making the light distribution more uniform and softer. This gives the anti-glare downlight 10 a better anti-glare effect and greatly improves the user experience.

[0035] In this embodiment, when the anti-glare downlight 10 is turned on, firstly, the light-emitting end of the light-emitting element 200 emits light and illuminates the refractive lens 320; then, the refractive lens 320 refracts the light emitted by the light-emitting element 200 onto the diffuse reflection layer 311 on the inner peripheral wall of the lampshade body 310, so that the diffuse reflection layer 311 can diffusely reflect the light, thereby reducing the intensity of the light and making the light softer and more uniform; finally, the light after being diffusely reflected by the diffuse reflection layer 311 will illuminate the target area through the floodlight 330, so that the floodlight 330 can diffuse the light, thereby further reducing the intensity of the light and making the light distribution more uniform and softer, greatly improving the anti-glare effect of the anti-glare downlight 10.

[0036] The aforementioned anti-glare downlight 10, with a diffuse reflection layer 311 formed on the inner peripheral wall of the lampshade body 310, is located at the light outlet 120. A refractive lens 320 is installed at the end of the lampshade body 310 adjacent to the light-emitting element 200, refracting light to the inner peripheral wall of the lampshade body 310. A floodlight plate 330 is installed at the end of the lampshade body 310 away from the light-emitting element 200, together forming a diffuse reflection cavity 340. This allows the refractive lens 320 to reflect light when it shines from the light-emitting end of the light-emitting element 200 onto the refractive lens 320. The light rays are refracted onto the inner peripheral wall of the lampshade body 310, and diffused by the diffuse reflection layer 311 on the inner peripheral wall of the lampshade body 310 to reduce the intensity of the light and make the light softer and more uniform. When the light after being diffused by the diffuse reflection layer 311 shines on the target area through the floodlight plate 330, the floodlight plate 330 can diffuse the light, further reducing the intensity of the light, thus making the light distribution more uniform and softer. As a result, the anti-glare downlight 10 has a better anti-glare effect and greatly improves the user experience.

[0037] like Figure 2 and Figure 5 As shown, in one embodiment, the lampshade body 310 is trumpet-shaped. The cross-sectional area of ​​the end of the lampshade body 310 adjacent to the light-emitting element 200 is smaller than the cross-sectional area of ​​the end of the lampshade body 310 away from the light-emitting element 200. This allows the light to gradually diffuse as it propagates within the diffuse reflection cavity 340, enabling the light to illuminate a wider area more evenly. This avoids glare or dazzling effects caused by excessive light concentration, greatly improving the anti-glare effect of the anti-glare downlight 10. At the same time, it also reduces the loss of light through diffuse reflection and refraction, allowing more light to shine out smoothly, greatly improving the utilization rate of light. Consequently, the anti-glare downlight 10 has a better lighting effect, thus greatly improving the user experience.

[0038] like Figures 2 to 6 As shown, in one embodiment, the refractive lens 320 is detachably mounted on the lampshade body 310 to facilitate the installation and removal of the refractive lens 320, thereby greatly reducing the difficulty of replacing the refractive lens 320 and thus reducing the maintenance difficulty of the anti-glare downlight 10.

[0039] like Figures 2 to 6As shown, in one embodiment, a first mounting hole 312 is formed at one end of the lampshade body 310 adjacent to the light-emitting element 200. A first threaded connection portion 3121 is formed in the first mounting hole 312, and a second threaded connection portion 321 is formed on the outer peripheral wall of the refractive lens 320. The first threaded connection portion 3121 is threadedly connected to the second threaded connection portion 321. This not only further reduces the difficulty of installing and disassembling the refractive lens 320, but also enables the refractive lens 320 to be securely fixed on the lampshade body 310. This prevents the refractive lens 320 from detaching from the first mounting hole 312 due to collisions or other external factors during daily use of the anti-glare downlight 10, greatly improving the stability of the anti-glare downlight 10 and thus greatly improving the user experience.

[0040] like Figures 2 to 6 As shown, in one embodiment, the floodlight 330 is detachably mounted on the lampshade body 310 to facilitate the installation and removal of the floodlight 330, which greatly reduces the difficulty of replacing the floodlight 330 and further reduces the maintenance difficulty of the anti-glare downlight 10.

[0041] like Figures 2 to 6 As shown, in one embodiment, a second mounting hole 313 is formed at the end of the lampshade body 310 away from the light-emitting element 200. A third threaded connection portion 3131 is formed in the second mounting hole 313. A fourth threaded connection portion 331 is formed on the outer peripheral wall of the floodlight plate 330. The third threaded connection portion 3131 is threadedly connected to the fourth threaded connection portion 331. This not only further reduces the difficulty of installing and disassembling the floodlight plate 330, but also enables the floodlight plate 330 to be securely fixed to the lampshade body 310. This prevents the floodlight plate 330 from detaching from the second mounting hole 313 during daily use due to collisions or other external factors. This further improves the stability of the anti-glare downlight plate 10 and greatly enhances the user experience.

[0042] like Figure 6 As shown, in this embodiment, the refractive lens 320 is a glass lens or a plastic lens.

[0043] like Figure 2 and Figure 6 As shown, in one embodiment, the refractive lens 320 is a concave lens, so that when the light emitted by the light-emitting element 200 passes through the refractive lens 320, the light will diverge away from the central axis of the refractive lens 320, so that the light can illuminate the diffuse reflection layer 311 of the lampshade body 310.

[0044] like Figure 2 and Figure 6As shown, in one embodiment, the concave lens is a biconcave lens to enhance the light divergence effect of the refractive lens 320.

[0045] like Figure 2 and Figure 3 As shown, in one embodiment, the connection position between the lampshade body 310 and the lamp body 100 is adjustable, so that the user can flexibly adjust the size and brightness of the light spot by adjusting the distance between the lampshade body 310 and the light-emitting element 200, thereby achieving more precise and personalized lighting control, meeting the lighting needs of different environments and occasions, and greatly improving the applicability of the anti-glare downlight 10.

[0046] like Figure 2 and Figure 3 As shown, in one embodiment, a fifth threaded connection portion 314 is formed on the outer peripheral wall of the lamp cover body 310, and a sixth threaded connection portion 130 is formed on the inner peripheral wall of the lamp body 100. The fifth threaded connection portion 314 is threadedly connected to the sixth threaded connection portion 130, which not only greatly reduces the difficulty of installing and disassembling the lamp cover body 310, but also makes it easier to adjust the size and brightness of the light spot of the anti-glare downlight 10, thereby greatly improving the ease of use of the anti-glare downlight 10.

[0047] like Figure 1 and Figure 2 As shown, in one embodiment, the lamp body 100 includes a lamp barrel 140 and a heat sink 150. The first end of the lamp barrel 140 forms a light outlet 120, and the second end of the lamp barrel 140 is fixedly connected to the heat sink 150 to form a mounting groove 110. The fixed end of the light-emitting element 200 is mounted on the side of the heat sink 150 facing the mounting groove 110, and the light-emitting end of the light-emitting element 200 is set facing the light outlet 120 so that the light-emitting element 200 can dissipate heat through the heat sink 150, so that the light-emitting element 200 can be maintained within the normal operating temperature range during use, thereby greatly improving the stability of the anti-glare downlight 10.

[0048] like Figure 2 As shown, in this embodiment, the lamp tube 140 and the heat sink 150 are integrally formed to improve the structural compactness of the lamp body 100.

[0049] Compared with the prior art, this disclosure has at least the following advantages:

[0050] The aforementioned anti-glare downlight 10, with a diffuse reflection layer 311 formed on the inner peripheral wall of the lampshade body 310, is located at the light outlet 120. A refractive lens 320 is installed at the end of the lampshade body 310 adjacent to the light-emitting element 200, refracting light to the inner peripheral wall of the lampshade body 310. A floodlight plate 330 is installed at the end of the lampshade body 310 away from the light-emitting element 200, together forming a diffuse reflection cavity 340. This allows the refractive lens 320 to reflect light when it shines from the light-emitting end of the light-emitting element 200 onto the refractive lens 320. The light rays are refracted onto the inner peripheral wall of the lampshade body 310, and diffused by the diffuse reflection layer 311 on the inner peripheral wall of the lampshade body 310 to reduce the intensity of the light and make the light softer and more uniform. When the light after being diffused by the diffuse reflection layer 311 shines on the target area through the floodlight plate 330, the floodlight plate 330 can diffuse the light, further reducing the intensity of the light, thus making the light distribution more uniform and softer. As a result, the anti-glare downlight 10 has a better anti-glare effect and greatly improves the user experience.

[0051] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure.
