Description

Technical Field

[0001] This utility model relates to the field of side turn signal technology, and in particular to a side turn signal with a light shield. Background Technology

[0002] Currently, the reflector openings of side turn signals are relatively large, resulting in a large exposed area of ​​the circuit board components, which is unsightly. Secondly, the large reflector openings also lead to low light source utilization; traditional reflective structures have a light flux utilization rate of only 42-45%. To meet regulatory light intensity requirements, manufacturers typically need to increase the number of LEDs. However, increasing the number of LEDs brings additional heat dissipation requirements, necessitating the design of additional heat dissipation structures. This not only complicates the lamp structure but may also increase production costs and maintenance difficulty. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a side turn signal with a light shield. By setting the light shield, it not only covers part of the exposed area of ​​the circuit board, but also improves the utilization rate of the light source, without the need to increase the number of LEDs or add a heat dissipation structure.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0005] A side turn signal with a light shield includes a lamp housing, on which a circuit board, a light shield, and a reflector are sequentially mounted. An opening is provided at the rear end of the reflector. The portion of the circuit board with LED lights is exposed at the opening of the reflector. The light shield is located at the front of the circuit board and covers the area of ​​the circuit board exposed at the opening of the reflector.

[0006] As a further implementation, the light-shielding plate is provided with several arc-shaped protrusions, the rear side of which forms a reverse reflective surface, and the reverse reflective surface faces the LED light.

[0007] As a further implementation, the protrusions are arranged in the same number and correspond to the LEDs on the circuit board.

[0008] As a further implementation, the arrangement direction of the protrusions is parallel to the arrangement direction of the LEDs on the circuit board.

[0009] As a further implementation, the protrusions are arranged along the edge of the light-shielding plate and exposed at the opening of the reflector.

[0010] As a further implementation, the reverse reflective surface is arranged in an arc shape, and the arrangement direction of the reverse reflective surface is opposite to the main light emission direction of the side turn signal, so as to re-emit unused stray light to the effective illumination area.

[0011] As a further implementation, the light-shielding plate is provided with fixing holes at both ends, and the light-shielding plate and the circuit board are fixed to the lamp housing through the corresponding fixing holes.

[0012] As a further implementation, the light-shielding plate is also provided with at least two sets of limiting holes.

[0013] As a further implementation, the positions of the two sets of fixing holes after the light shield is installed correspond to a set of diagonal positions on the lamp housing.

[0014] As a further implementation, the arrangement direction of the plurality of protrusions is parallel to the direction of the line connecting the two sets of fixing holes.

[0015] The beneficial effects of this utility model are as follows:

[0016] This invention's light-shielding plate covers most of the exposed area of ​​the circuit board, leaving only a small portion exposed, effectively blocking the visual exposure of the circuit board in traditional lighting fixtures and significantly improving the product's appearance and aesthetics. Furthermore, the light-shielding plate effectively reduces the opening of the reflector, increasing the utilization rate of the light source. The raised areas on the light-shielding plate create a reverse reflective surface, reflecting stray light that would otherwise be unused in traditional designs back to the effective lighting area, further enhancing the light source utilization rate. This invention improves light source utilization by using a light-shielding plate without requiring additional LEDs or a dedicated heat dissipation structure.

[0017] This invention achieves the dual technical effects of optimizing appearance and improving optical performance. The overall structure is designed as an integrated unit, eliminating the need for additional optical components. Attached Figure Description

[0028] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0029] Example 1

[0030] In a typical embodiment of this utility model, refer to Figures 1-6 As shown, a side turn signal with a light shield is provided. The side turn signal includes a lamp housing 1, and a circuit board 3, a light shield 4 and a reflector 2 are sequentially mounted on the surface of the lamp housing 1 from the inside to the outside.

[0031] The reflector has an opening 21 at its rear end, and the portion of the circuit board with LED lights 31 is exposed at the opening of the reflector. In this embodiment, the light-shielding plate 3 is located on the front side of the circuit board 4 and covers the area of ​​the circuit board 4 exposed at the opening of the reflector 2.

[0032] A light shield 4 is set between the circuit board 3 and the reflector 2 to cover most of the exposed area of ​​the circuit board 3, leaving only a small part exposed. This effectively blocks the visual exposure of the circuit board 3 in traditional side turn signal lamps, significantly improving the appearance integrity and aesthetics of the product.

[0033] like Figures 2-6 As shown, the light-shielding plate 4 has several arc-shaped protrusions 41, which protrude outwards from the lamp housing. The rear side of the protrusions 41 forms a reverse reflective surface 411, which faces the LED lamp 31. The protrusions correspond to and are the same number as the LED lamps 31 on the circuit board.

[0034] In this embodiment, the circuit board has four LED lights 31, and the light shield 4 has four corresponding protrusions 41.

[0035] Each protrusion corresponds one-to-one with each LED 31, and the arrangement direction of the protrusions 41 is parallel to the arrangement direction of the LEDs 31 on the circuit board. For example... Figure 3 As shown, the arrangement direction of the protrusions 41 and the arrangement direction of the LED lights 31 on the circuit board are both inclined.

[0036] In this example, the reverse reflector 41 is arranged in an arc shape. The arrangement direction of the reverse reflector 41 is opposite to the main light emission direction of the side turn signal, that is, the center of the reverse reflector 411 is directly facing the main light emission direction. The purpose of this structural arrangement is to enable the unused stray light to be re-emitted to the effective lighting area, thereby greatly improving the utilization rate of the light source.

[0037] Understandably, the angle of the reflective surface is adjustable. According to experimental verification, the reflection angle of the reverse reflective surface can be corrected, and the light distribution curve can be optimized according to different lighting needs to achieve better lighting effects and higher light source utilization.

[0038] like Figure 5 and Figure 6 As shown, the light-shielding panel is a plate structure, consisting of two connected sections, such as... Figure 3 As shown, the first section of the light shield is close to the left side of the lamp housing, and the second section is close to the bottom edge of the lamp housing.

[0039] The light-shielding plate 4 has fixing holes at both ends, through which the light-shielding plate 4 and the circuit board 3 are fixed to the lamp housing. The top of the first section of the light-shielding plate 4 has a first fixing hole 42, and the right end of the second section has a second fixing hole 43. The fixing plate is fixed to the lamp housing using the fixing holes and screws. The positions of the two sets of fixing holes on the light-shielding plate 4 after installation correspond to a set of diagonal positions (upper left corner and lower right corner) on the lamp housing 1, such as... Figure 3 As shown.

[0040] Understandably, circuit board 3 has through holes corresponding to the fixing holes, and screws can be used to fix the light shield and circuit board to the lamp housing simultaneously.

[0041] The light shield 4 is also provided with at least two sets of limiting holes, namely a first limiting hole 44 and a second limiting hole 45. A limiting pin can be correspondingly provided on the lamp housing. The limiting pin cooperates with the limiting hole to limit the installation of the light shield 4. The positions of the first limiting hole 44 and the second limiting hole 45 on the light shield are determined according to the position of the limiting pin. In this embodiment, the first limiting hole 44 is provided at the connection between the two sections of the light shield, and the second limiting hole 45 is provided on one side of the second fixing hole 43.

[0042] In this embodiment, when installing the light shield 4, the limiting hole on the light shield 4 cooperates with the corresponding limiting pin on the lamp housing 1 to achieve the positioning of the light shield 4 during installation.

[0043] like Figure 3 and Figure 5 , Figure 6 As shown, protrusions 41 are arranged on the second section of the longer light shield and are located on the upper edge of the second section. The arrangement direction of protrusions 41 is inclined relative to the bottom edge of the lamp housing, and protrusions 41 are exposed at the opening 21 of the reflector 2.

[0044] In this example, the arrangement direction of the protrusions 41 is parallel to the direction of the line connecting the two sets of fixing holes. Alternatively, in other examples, the angle between the arrangement direction of the protrusions 41 and the direction of the line connecting the two sets of fixing holes is an acute angle, less than 20°.

[0045] The installation of reflector 2 is a prior art technique, such as... Figure 2 As shown, by installing a light-shielding plate 4 between the circuit board 3 and the reflector 2, the light-shielding plate 4 can cover a portion of the area at the opening 21 of the reflector 2. Specifically, the area covered is the area between the LED light 31 on the circuit board and the bottom edge of the opening, such as... Figure 2 As shown, this reduces the exposed area of ​​the circuit board.

[0046] In this embodiment, the light-shielding plate 4 covers most of the exposed area of ​​the circuit board 3, leaving only a small portion exposed. This structural design effectively blocks the visual exposure of the circuit board 3 in traditional lighting fixtures, significantly improving the product's appearance and aesthetics. Furthermore, the light-shielding plate 4 effectively reduces the opening of the reflector 2, thereby improving the utilization rate of the light source.

[0047] The light-shielding plate 4 has a raised section 41 forming a reverse reflective surface 411 on its back side. The reverse reflective surface 411 is arranged in the opposite direction to the main light emission direction. Testing has shown that this structure can reflect stray light that would otherwise be unusable in traditional designs back into the effective lighting area, significantly improving the utilization rate of the light source.

[0048] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
