AI Technical Summary
The LED chips in existing lights are prone to causing a grainy appearance, which affects the user experience. This graininess is particularly noticeable in environments where luminous flux requirements are not high. The graininess is especially pronounced in ambient lights such as wall lights or night lights. In particular, existing technologies cannot effectively reduce the graininess of lighting fixtures in environments where luminous flux requirements are not high.
By setting a groove in the light guide plate and filling the light guide groove with flexible EVA or silicone, the light guide plate with a groove and filling with flexible EVA or silicone can serve as a light-blocking material, reducing the graininess of the LED beads.
It effectively reduces the graininess of the LED beads. Although the luminous flux is reduced, it still meets the needs of users of wall lamps, night lights, and ambient lights that do not have high requirements for luminous flux.

Abstract
Description
Technical Field
[0001] This utility model relates to lighting devices, and more particularly to LED lights. Background Technology
[0002] Existing LED lights typically have an acrylic lampshade surrounding the LED chip. While the light emitted by the chip can pass through the acrylic lampshade, the LED chip itself is still clearly visible from the front of the acrylic lampshade, exhibiting a noticeable grainy appearance. This is particularly problematic for environments where high luminous flux isn't required, such as wall lights, nightlights, or ambient lights, as the excessive graininess can create a negative user experience. Utility Model Content
[0003] The main technical problem to be solved by this utility model is to provide an anti-glare structure that can reduce the graininess of the LED beads on the light-emitting side.
[0004] To solve the above-mentioned technical problems, this utility model provides an anti-glare structure, including: a light guide plate and an LED light source plate. The light-emitting surface of the light guide plate is aligned with the light-emitting surface of the LED light source plate. The light guide plate is provided with grooves along the direction of light path transmission to reduce the graininess of the LED light source plate at the light-emitting surface of the light guide plate.
[0005] In a preferred embodiment, the groove is filled with a light-blocking material.
[0006] In a preferred embodiment, the light-blocking material is flexible EVA or silicone.
[0007] This utility model also provides an LED lamp equipped with the anti-glare structure described above.
[0008] In a preferred embodiment: the LED light source board is disposed around the circumference of the lamp body on the side wall of the lamp body.
[0009] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:
[0010] This invention provides an anti-glare structure. By setting a groove inside the light guide plate, the graininess of the LED beads can be greatly reduced. By filling the groove with a light-blocking material, the graininess can be completely eliminated. Although the light-blocking material reduces the luminous flux, for lighting fixtures such as wall lights, night lights, and ambient lights, which do not have high requirements for luminous flux, reducing some luminous flux while reducing the graininess of the LED beads is perfectly in line with user needs.

[0015] To make the technical solution and features of this utility model clearer, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific examples. It should be understood that these examples are only for illustrating this utility model and are not intended to limit the scope of this utility model. After reading this utility model, any modifications of this utility model by those skilled in the art in various equivalent forms fall within the scope defined by the appended claims.
[0016] refer to Figures 1-4 This embodiment provides an LED lamp equipped with an anti-glare structure. The anti-glare structure includes a light guide plate 1 and an LED light source plate 2. The light-emitting surface of the light guide plate 1 is aligned with the light-emitting surface of the LED light source plate 2. The light guide plate 1 has grooves 11 along the direction of light transmission to reduce the graininess of the LED light source plate 2 at the light-emitting surface of the light guide plate 1. In this embodiment, the LED light source plate 2 is arranged around the circumference of the lamp body 3 on its side wall. The LED light source plate 2 can also be linear or of any shape, not limited to a ring shape. The shape of the lamp body 3 can also be arbitrary, not limited to this embodiment.
[0017] To further eliminate the grainy texture, the groove 11 is filled with a light-blocking material. The light-blocking material is flexible EVA or silicone.
[0018] The aforementioned anti-glare structure, by setting a groove 11 within the light guide plate 1, can significantly reduce the graininess of the LED beads. Filling the groove 11 with a light-blocking material completely eliminates the graininess. Although the light-blocking material reduces luminous flux, for lighting fixtures such as wall lights, night lights, and ambient lights where luminous flux requirements are not high, reducing some luminous flux while minimizing the graininess of the LED beads perfectly meets user needs.
[0019] The above is only one specific embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
