Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to an anti-glare LED lamp based on polarized light reflection technology. Background Technology

[0002] Current LED lighting fixtures primarily rely on diffusers to homogenize light and suppress glare, but this single solution has significant limitations. The scattering mechanism of diffusers only reduces the direct brightness of the light source, lacking the ability to specifically suppress directional reflected glare from smooth surfaces. For example, in exhibition hall spotlights, the light reflected from glass display cases creates high-brightness spots, severely interfering with the observation of exhibits; in still life photography, reflected light from metal or glassware often leads to localized overexposure, damaging image quality; and under table lamps, tabletop reflections exacerbate visual fatigue.

[0003] Therefore, it is necessary to propose an anti-glare LED lamp based on polarized light reflection technology to solve the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figure 1-4As shown, an anti-glare LED lamp based on polarized light reflection technology includes a lampshade 2, an LED light source 4 inside the lampshade 2, and an anti-glare lens 6 at the light outlet of the lampshade 2. The anti-glare lens 6 is composed of a diffuser plate 15, a polarizing film 16, and a transparent plate 17 stacked sequentially. The diffuser plate 15 is located on the side of the polarizing film 16 closer to the LED light source 4. A support frame 3 is fixedly connected to the edge of the anti-glare lens 6, and the support frame 3 is rotatably connected to the lampshade 2. A pin 12 is slidably connected to the upper part of the support frame 3. Multiple slots 13 that are adapted to the pins 12 are opened along the circumference of the outer side of the lampshade 2. Specifically, the polarizing film 16 is a linearly polarized film.

[0025] By setting up a diffuser plate 15, the bright spots directly from the LED light source 4 are reduced, making the light source more uniform and softer. By setting up a linear polarizing film, only light waves with the same polarization direction are retained, while light in other directions is blocked, resulting in linearly polarized light output. A transparent plate 17 is set up to protect the polarizing film 16. In use, the support frame 3 is rotated according to the observation angle to dynamically adjust the light transmission axis direction of the polarizing film 16 so that it is perpendicular to the polarization direction of the reflected glare at the observation angle, thereby suppressing glare. After adjustment, the pin 12 is inserted into the slot 13 to fix the anti-glare lens 6.

[0026] In some embodiments, in order to facilitate the installation of the anti-glare lens 6, the support frame 3 includes a positioning ring 7 and a frame 9. The positioning ring 7 and the frame 9 are fixedly connected by screws 8, and an annular limiting groove adapted to the edge of the lampshade 2 is formed between the positioning ring 7 and the frame 9.

[0027] When installing the anti-glare lens 6, the positioning ring 7 is placed on the outside of the lampshade 2, and the frame 9 is placed on the light outlet of the lampshade 2. Finally, the positioning ring 7 and the frame 9 are fixed with screws 8. With the cooperation of the positioning ring 7 and the frame 9, an annular limiting groove that matches the edge of the lampshade 2 is formed, thereby realizing the rotational connection between the lampshade 2 and the support frame 3.

[0028] To facilitate the rotation of the anti-glare lens 6, a groove 11 is provided on the inner side of the frame 9. The pin 12 is slidably connected to the frame 9 through the groove 11, and a spring 10 is provided at the end of the pin 12 away from the slot 13. Preferably, both the groove wall of the slot 13 and the end of the pin 12 are provided with bevels.

[0029] When the anti-glare lens 6 is rotated, the inclined plane pushes the pin 12 to retract into the pin 12, and the spring 10 is compressed. When the pin 12 moves to the next slot 13, the spring 10 pushes one end of the pin 12 into the slot 13, thereby realizing the positioning of the rotation angle of the anti-glare lens 6.

[0030] To improve the heat dissipation of the LED light source 4, heat dissipation fins 1 are added to the outer side of the lampshade 2 at the position corresponding to the LED light source 4. An insulating thermally conductive pad 5 is also placed between the LED light source 4 and the lampshade 2. This design enhances the thermal conductivity between the LED light source 4 and the lampshade 2 through the insulating thermally conductive pad 5, and improves the heat dissipation efficiency of the lampshade 2 through the heat dissipation fins 1, thereby further enhancing the overall heat dissipation effect.

[0031] The interior of the lampshade 2 is equipped with a reflective coating. By setting a reflective cup-shaped reflective coating, the light shining on the inner wall of the lampshade 2 is reflected to the light outlet, reducing light loss.

[0032] It should be noted that this LED light fixture is suitable for still life photography lighting, table lamps, exhibition hall lighting, and other scenarios where the viewing angle is fixed or changes little.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
