Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, specifically to a luminous ring-shaped decorative ring. Background Technology

[0002] Existing light-emitting lens rings employ a method where LEDs are positioned at the base of the ring's transparent or milky-white material. The LEDs directly illuminate the transparent or milky-white material, causing the ring to glow. For example, the annular light guide ring disclosed in publication number CN214198360U uses this method. However, these existing light-emitting lens rings have the following problems: when transparent material is used for the luminous portion of the ring, direct LED illumination results in noticeable graininess and poor uniformity; the LED circuit board is positioned at the base of the entire luminous area, occupying a significant amount of space and limiting the space and shape of the ring's base. Utility Model Content

[0003] To address the aforementioned issues, this utility model provides a light-emitting ring-shaped decorative ring that emits light throughout the entire ring with good uniformity, avoiding noticeable bright spots when viewed from conventional angles, while also having a small footprint on its circuit board.

[0004] The technical solution is as follows: a light-emitting ring-shaped decorative ring, comprising an LED module and a decorative ring assembly. The decorative ring assembly includes a decorative ring base, a transparent decorative ring, and a decorative ring cover plate. The transparent decorative ring is fitted onto the root of the decorative ring base. The decorative ring cover plate is connected to the decorative ring base and restricts the transparent decorative ring between the decorative ring cover plate and the decorative ring base. The decorative ring base has a mounting groove at its root. The annular portion of the transparent light guide is placed in the mounting groove. The transparent decorative ring is positioned opposite the annular portion of the transparent light guide to guide light into the transparent decorative ring and cause its lateral inclined light-emitting surface to emit light. The light-incident end of the transparent light guide is connected to the LED module. The light-incident end extends vertically and is tangent to the annular portion.

[0005] Furthermore, the base of the decorative ring and the transparent decorative ring are respectively protruding and conical, and the cover plate of the decorative ring has a through hole in the middle. The cover plate of the decorative ring passes through the through hole through the protruding part of the base of the decorative ring and the transparent decorative ring and covers the root of the transparent decorative ring.

[0006] Furthermore, the decorative ring cover is connected to the decorative ring base via a locking structure.

[0007] Furthermore, the transparent decorative ring has a pattern on its side.

[0008] Furthermore, the base of the decorative ring and the cover plate of the decorative ring are made of opaque material.

[0009] Beneficial effects: By using a ring-shaped light guide set in the base of the decorative ring to transmit light, not only can the light enter the transparent decorative ring more evenly, but the use of circuit boards can also be reduced, thereby reducing the space occupied. At the same time, because the light-emitting surface of the transparent decorative ring is tilted on the side, the light inside the transparent decorative ring is gradually reflected out of the transparent decorative ring as it travels, so that the entire decorative ring is lit with good uniformity. The above structure also avoids the LED shining directly on the side wall of the transparent decorative ring, thus avoiding the bright spot produced by the LED being directly observed from the decorative ring. In addition, the light-inlet end of the transparent light guide extends vertically, so that unless viewed from a downward direction, the light entering the ring part from the light-inlet end of the transparent light guide cannot be observed, thus avoiding the observation of the incident light (i.e., bright spot) from the light-inlet end from conventional angles.

[0014] Figure 5 for Figure 3 BB-directed sectional view. Detailed Implementation

[0015] like Figure 1 , Figure 2 , Figure 3 The illustrated luminous ring includes an LED module 1 and a ring assembly. The ring assembly includes a ring base 2, a transparent ring 4, and a ring cover plate 5. The transparent ring 4 is fitted onto the root of the ring base 2. The ring cover plate 5 is connected to the ring base 2 and restricts the transparent ring 4 between the ring cover plate 5 and the ring base 2. The root of the ring base 2 is provided with a mounting groove 21. The annular portion of the annular transparent light guide 3 is placed in the mounting groove 21. The transparent ring 4 is positioned opposite the annular portion of the transparent light guide 3 to guide light into the transparent ring 4 and make its side-extending luminous surface emit light. The light-incident end of the transparent light guide 3 is connected to the LED module 1 and extends vertically and is tangent to the annular portion.

[0016] Specifically, the base 2 and the transparent ring 4 protrude and are cone-shaped. The base of the transparent ring 4 has sufficient thickness to allow the light in the transparent light guide 3 to fully penetrate the side wall of the transparent ring 4. The cover plate 5 has a through hole in the middle. The cover plate 5 passes through the through hole and passes through the protruding parts of the base 2 and the transparent ring 4 and covers the base of the transparent ring 4.

[0017] Furthermore, for ease of assembly, the ring cover plate 5 can be connected to the ring base 2 via a locking structure 51. To further diffuse light, the sides of the transparent ring 4 are patterned. The ring base 2 and the ring cover plate 5 are made of opaque material, thus allowing the base to be shielded through the opaque ring cover plate 5.

[0018] When using, combine Figure 4 , Figure 5 The LED on LED module 1 emits light, and the light enters the light guide 3 through the light inlet end. Then, the light is guided to the root of the transparent decorative ring 4 through the light distribution pattern on the ring light guide, so that the pattern on the transparent decorative ring 4 emits light, achieving the effect of ring-shaped light emission.

[0019] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
