Description

Technical Field

[0001] This application relates to the field of lighting device technology, specifically to an anti-glare lighting device with adjustable light emission angle. Background Technology

[0002] Adjustable-angle LED lights already exist in the prior art. For example, the structure disclosed in the utility model patent with authorization announcement number CN208919859U mainly consists of a lamp holder and a movable cover. The lamp holder includes a plate base and a seat body inserted into the plate base. The movable cover consists of a movable seat and a top cover. The movable seat rotates by the cooperation of the locking part with the through hole of the plate base, thereby driving the entire lamp to adjust the light emission angle, which to some extent solves the problem of limited illumination range of fixed-angle lamps.

[0003] However, when these adjustable-angle LED lights are actually used for mirror lighting or decorative lighting, there are still obvious defects: First, when used as a mirror light, the lamp holder is fixedly installed on the wall. At this time, the lamp holder emits light in front of the mirror, that is, directly facing the user's face. The light can easily shine directly into the user's eyes, forming strong glare, causing visual fatigue and blurred vision. At the same time, it destroys the uniformity of facial light, making it impossible to clearly present facial details, which violates the original intention of the mirror light as an auxiliary lighting. Even if the angle is adjusted by rotating the movable cover, the problem of the light shining directly forward cannot be fundamentally solved. Utility Model Content

[0020] Reference Figures 1-5 The present application proposes an embodiment of the anti-glare lighting device with adjustable light emission angle, which includes: Bracket 10 is used for fixed installation on the front side of the fixed body; The lamp housing 20 is rotatably mounted on the front side of the bracket 10. A locking structure 30 for locking the two is provided between the lamp housing 20 and the bracket 10. A light-transmitting part 50 is provided on the rear side of the lamp housing 20. Light source 40 is disposed inside the lamp housing 20; The lamp housing 20 can rotate under the action of external force so that the light-transmitting part 50 rotates upward or downward.

[0021] The lamp housing 20 is hollow inside, and the light source 40 is an LED light panel. The lamp housing 20 is rotatably mounted on the front side of the bracket 10. The lamp housing 20 can rotate relative to the bracket 10, thereby adjusting the light-emitting part of the lamp housing 20 up and down. When the adjustable anti-glare lighting device described in this embodiment is used as a mirror light, the lamp housing 20 is rotated so that the light-transmitting part 50 faces up or down. After the light is emitted through the light-transmitting part 50, it is projected diagonally upward or downward to avoid directly facing the user's face, i.e., in front of the mirror, thus reducing direct glare. When used as a wall lamp to illuminate decorative items, the light can be precisely projected onto the top or bottom of the decorative item by rotating the light-transmitting part 50 degrees up and down.

[0022] The light-transmitting part 50 of this application is positioned rearward to change the direction of direct light, preventing light from directly entering the human eye and solving the glare problem of traditional lamps in front of mirrors or decorative lighting. At the same time, it meets the lighting needs of mirror lights and can also be adapted to directional lighting of decorative items. The lamp housing 20 can rotate flexibly and be fixed by the locking structure 30, which makes it convenient for users to change the light emission angle according to their needs and is suitable for different usage requirements.

[0023] Preferably, the cross-section of the light-transmitting portion 50 is semi-circular.

[0024] The cross-section of the light-transmitting part 50 is semi-circular, and its curved surface allows light to diffuse at a wider angle along the tangent of the arc when emitted. The semi-circular cross-section, through continuous refraction of the curved surface, ensures a wide illumination coverage area during vertical rotation adjustment. Especially when the lamp housing 20 rotates upwards or downwards to its extreme angle, the curved edge guides some light to be emitted obliquely outwards, reducing blind spots caused by angle deflection. This structural feature increases the effective illumination angle range of the device at the same rotation amplitude, satisfying the need for wide-area uniform lighting in front of mirrors and adapting to lighting scenarios with different heights and widths of decorative items, significantly improving the practicality of angle adjustment and the flexibility of lighting coverage.

[0025] In this embodiment, the lamp housing 20 is provided with extensions 21 on both sides of the front side. The lamp housing 20 can rotate relative to the bracket 10 until the extensions 21 contact the fixing body or the bracket 10 to limit the rotation range of the lamp housing 20.

[0026] When the lamp housing 20 rotates upwards or downwards to its maximum angle, the upper extension 21, as shown in the attached diagram, contacts the surface of the fixed body; when the lamp housing 20 rotates downwards to its maximum angle, the lower extension 21 contacts the surface of the fixed body, mechanically preventing the lamp housing 20 from continuing to rotate. The length of the extension 21 can be designed according to a preset rotation range to ensure that the rotation angle of the lamp housing 20 is within the effective lighting range.

[0027] In another embodiment, the extension 21 may be rotated to contact the surface of the bracket 10 to limit the rotation range of the lamp housing 20.

[0028] In this embodiment, after the lamp housing 20 is rotated upward by 90° or downward by 90°, the extension 21 comes into contact with the fixing body.

[0029] In this embodiment, the fixing body is a wall. In this embodiment, the lamp housing 20 is rotated upward by 90° or downward by 90°, and the rear side of the extension 21 is flush with the rear side of the bracket 10.

[0030] Preferably, the light-transmitting part 50 has an anti-glare structure.

[0031] The anti-glare structure transforms concentrated direct light into soft, diffused light. Even if there is a slight risk of direct light due to angle adjustment, the structure can weaken the strong light stimulation, further reducing the probability of glare, while improving the brightness uniformity of the irradiated area.

[0032] The anti-glare structure can be formed by setting a light outlet on the lamp housing 20 and setting a light-transmitting cover at the light outlet, and the light-transmitting cover is frosted, has a micro-prism array, or is coated with an anti-glare coating.

[0033] In this embodiment, the anti-glare structure adopts an anti-glare dual-lens structure. Specifically, the anti-glare dual-lens structure includes a first transparent lens 52 and a second transparent lens 51. The first transparent lens 52 is disposed on the side of the second transparent lens 51 close to the light source 40. Both the first transparent lens 52 and the second transparent lens 51 are provided with prism microlens arrays on the side facing away from the light source 40, and the shapes of the prism microlens arrays on the first transparent lens 52 and the second transparent lens 51 are different.

[0034] The prism microlenses can be square, rhomboid, circular, polygonal, or elliptical in shape. In this embodiment, the beam angle of the light emitted from the light source 40 after passing through the first transparent lens and the second transparent lens 51 is 10°-90°. The prism microlens array can be selected according to the required illumination spot range.

[0035] In this embodiment, the light emitted by the light source 40 is dispersed after being refracted by the first transparent lens and then by the second transparent lens 51. The first transparent lens initially refracts the light before it shines onto the second transparent lens 51, where the prism microlens array refracts the dispersed light again, further widening the beam angle and causing them to overlap, ultimately forming diffused light with a wide coverage and uniform intensity. The different shapes of the prism microlenses in the two transparent lenses avoid localized light spots caused by a single direction of light refraction, significantly reducing glare.

[0036] Furthermore, the first transparent lens and the second transparent lens 51 are provided with a Fresnel structure, a fly-eye transparent lens structure or a compound eye transparent lens structure on the side facing the light source 40; or the second transparent lens 51 is provided with a Hartmann array on the side facing the light source 40.

[0037] The light emitted from the light source 40 first contacts the side of the first transparent lens facing the light source 40. The Fresnel structure refracts the divergent light into a parallel beam through the refraction of the ring pattern, reducing the brightness difference between the center and the edge of the light source 40. The fly-eye / compound-eye structure splits the single beam of light into multiple uniform sub-beams, avoiding uneven brightness of the light source 40 itself. The Hartmann array, through the synergistic effect of multiple small lenses, compensates for the scattering deviation of the light during propagation, ensuring a more stable light output angle after passing through the double lens, thereby further improving the anti-glare effect and illumination uniformity.

[0038] In one embodiment, the locking structure 30 may employ a damping pivot 11, allowing the lamp housing 20 to rotate relative to the bracket 10 under external force and to be locked at the current angle.

[0039] In this embodiment, the locking structure 30 includes a plurality of first protrusions 31. The two ends of the front side of the bracket 10 are respectively provided with mounting brackets. The lamp housing 20 is disposed between the two mounting brackets and rotatably connected to them. The plurality of first protrusions 31 are evenly spaced around the rotation center of the bracket 10 on the mounting bracket. The lamp housing 20 is provided with second protrusions 32, and the second protrusions 32 extend into the groove between two adjacent first protrusions 31.

[0040] When the lamp housing 20 rotates, the first protruding tooth 31 and the second protruding tooth 32 slide relative to each other. The second protruding tooth 32 temporarily disengages from the tooth groove due to elastic deformation. After rotating to the target angle, the second protruding tooth 32 re-engages between the adjacent first protruding teeth 31 under the action of elastic force. The friction generated by the meshing of the tooth surfaces restricts the rotation of the lamp housing 20. Since the first protruding teeth 31 are evenly distributed, multi-angle locking can be achieved to meet the angle requirements of different scenarios.

[0041] In this embodiment, multiple second protruding teeth 32 are provided, and these multiple second protruding teeth 32 are circumferentially spaced around the rotation center of the bracket 10. Multiple second protruding teeth 32 simultaneously engage with the first protruding teeth 31, which can disperse the force borne by a single protruding tooth and avoid wear or deformation of the protruding teeth due to long-term use. At the same time, the engagement of multiple protruding teeth increases the number of contact points, improving the overall friction of the locking structure 30. Even if one protruding tooth is slightly damaged, the remaining protruding teeth can still maintain the locking function, ensuring the angular stability of the lamp housing 20.

[0042] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
