[0026] In the description of the present invention, unless otherwise clearly defined, words such as "set", "installed", "connected", etc. should be understood in a broad sense. Those skilled in the art can reasonably determine the specific meanings of the above words in the present invention in combination with the specific content of the technical solution.

[0027] Refer to Figure 1 and Figure 2As shown, a motor vehicle position lamp structure according to an embodiment of the present invention includes a lamp housing 100, an LED light source 200, a first diffuser 300, a second diffuser 500, and a lens 400; the LED light source 200 is disposed within the lamp housing 100; the first diffuser 300 is disposed on the irradiation path of the LED light source 200, and the reflecting surface of the second diffuser 500 faces the reflecting surface of the first diffuser 300. Specifically, the second diffuser 500 is disposed below the first diffuser 300, and the second diffuser 500 and the first diffuser 300 form a light output channel 700; the lens 400 is used for light to exit, and the lens 400 is disposed at one end of the light output channel 700 away from the LED light source 200, and the lens 400 is disposed in a region where the direct light from the LED light source 200 does not exit. The light is emitted from the LED light source 200 and irradiates on the reflecting surface of the first diffuser 300. Subsequently, most of the reflected light of the first diffuser 300 is incident on the reflecting surface of the second diffuser 500 for a second diffuse reflection. Part of the reflected light of the second diffuser 500 is reflected back onto the first diffuser 300 for a third diffuse reflection and then passes through the lens 400 and irradiates to the outside. Part of the reflected light of the second diffuser 500 directly passes through the lens 400 and irradiates to the outside. Thus, after the light is emitted from the LED light source 200 and enters the light output channel 700, through the diffuse reflections of the first diffuser 300 and the second diffuser 500, the light distribution becomes more uniform, so that the light emitted to the outside through the lens 400 becomes soft and uniform, not dazzling, extremely beautiful, and greatly improves the visual effect. Preferably, the lens 400 is provided as colorless transparent or red transparent.

[0028] As Figure 2 shown, in some embodiments of the present invention, the light output channel 700 gradually increases in the direction from the LED light source 200 to the lens 400, so that the light emitted from the LED light source 200 is diffusely reflected by the first diffuser 300 and then incident on the second diffuser 500. Subsequently, a large part of the light emitted after the diffuse reflection by the second diffuser 500 is reflected back onto the reflecting surface of the first diffuser 300 for a third diffuse reflection and finally emitted to the outside through the lens 400; a large part of the light emitted from the LED light source 200 undergoes three diffuse reflections, making the light distribution more uniform respectively, so that the light emitted to the outside becomes softer and more uniform, not dazzling, extremely beautiful, and greatly improves the visual effect. Specifically, the length of the second diffuser 500 is less than the length of the first diffuser 300, and such a setting can ensure that a large part of the light emitted from the second diffuser 500 is reflected back onto the reflecting surface of the first diffuser 300.

[0029] As Figure 1 and Figure 2As shown, in some embodiments of the present invention, the first diffuser plate 300 is disposed above the second diffuser plate 500. One end of the first diffuser plate 300 facing the lens 400 is inclined upward relative to the second diffuser plate 500, and an acute angle is formed between the first diffuser plate 300 and the second diffuser plate 500. With this setting, a large part of the light emitted from the second diffuser plate 500 can be reflected back to the emitting surface of the first diffuser plate 300 for the third diffuse reflection, and finally pass through the lens 400 and be emitted to the outside, ensuring that the light emitted to the outside is soft, uniform, not dazzling, and greatly improving the visual effect. It can be understood that when the first diffuser plate 300 is disposed below the second diffuser plate 500, one end of the first diffuser plate 300 facing the lens 400 is inclined downward relative to the second diffuser plate 500, and the same technical effect can also be achieved.

[0030] As Figure 1 and Figure 2 shown, specifically, the first diffuser plate 300 includes an arc segment 310 and a horizontal segment 320. One end of the arc segment 310 facing the lens 400 is inclined upward relative to the second diffuser plate 500, and the horizontal segment 320 is disposed at one end of the arc segment 310 facing the lens 400. Most of the light emitted by the LED light source 200 is reflected onto the second diffuser plate 500 through the inclined arc segment 310, and the light that has undergone three diffuse reflections can basically pass through the lens 400 and be emitted to the outside through the horizontal segment 320. It can be understood that when the first diffuser plate 300 is disposed below the second diffuser plate 500, one end of the arc segment 310 facing the lens 400 is inclined downward relative to the second diffuser plate 500, and the same technical effect can also be achieved. Of course, this is only a preference for the structure of the first diffuser plate 300, and the first diffuser plate 300 can be set in an arc shape or a straight shape according to actual needs.

[0031] As Figure 1 and Figure 2 shown, in some embodiments of the present invention, a diffuser plate 600 is disposed between the light output channel 700 and the lens 400, and the width of the diffuser plate 600 is smaller than the width of the end port of the light output channel 700 facing the lens 400. The light that has undergone diffuse reflection treatment in the light output channel 700 is further scattered by the diffuser plate 600, making the light softer, more uniform, and not dazzling, further improving the visual effect; by setting the width of the diffuser plate 600 to be smaller than the width of the end port of the light output channel 700 facing the lens 400, the entire diffuser plate 600 can be fully illuminated by light, avoiding the appearance of dark areas and affecting the visual effect. Specifically, the diffuser plate 600 is set to be white and semi-transparent.

[0032] As Figure 1 and Figure 2As shown, the lamp housing 100 is provided with an opening for accommodating the end of the light outlet channel 700 away from the LED light source 200; the outer edge of the scattering plate 600 is provided with a light blocking member 610, and the light blocking member 610 is fixed in the opening. The light blocking member 610 can avoid the problem of light leakage at the outer edge of the scattering plate 600, and further improve the visual effect. Specifically, the light blocking member 610 and the scattering plate 600 are generally formed by secondary injection molding.

[0033] In some embodiments of the present invention, the second diffuse reflection plate 500 is replaced by a light absorbing plate, and the side of the light absorbing plate facing the first diffuse reflection plate 300 is set as a black light absorbing surface, and the black light absorbing surface can reduce the intensity of the light incident on the second diffuse reflection plate 500, making the light softer. Specifically, the light absorbing plate is set as a circuit board with a black surface. The second diffuse reflection plate 500 can be replaced with a light absorbing plate, further improving the flexibility of the embodiments of the present invention.

[0034] In some embodiments of the present invention, the first diffuse reflection plate 300 and the second diffuse reflection plate 500 are set as one body. The first diffuse reflection plate 300 and the second diffuse reflection plate 500 formed as one body can reduce the assembly process and improve the assembly accuracy, so that the light can be accurately diffusely reflected by the first diffuse reflection plate 300 and the second diffuse reflection plate 500, so that the light emitted to the outside is softer and more uniform. Of course, here is only a preferred structure of the two. According to actual needs, the two can be set as separate components to further improve the flexibility of the embodiments of the present invention.

[0035] In some embodiments of the present invention, the reflective surfaces of the first diffuse reflection plate 300 and the second diffuse reflection plate 500 are both set to white non-aluminum-plated surfaces. The white non-aluminum-plated surface can make the light incident on the first diffuse reflection plate 300 more evenly distributed. It is understandable that, according to actual needs, setting the second diffuse reflection plate 500 to a black non-aluminum-plated surface can also achieve the same technical effect.

[0036] like Figure 1 and Figure 2 As shown, the motor vehicle according to the second embodiment of the present invention includes the motor vehicle position light structure of the above embodiment, which has strong versatility and can be installed as a front position light or a rear position light. Since the lens 400 is arranged in the non-LED light source 200 direct light emission area; after the light is emitted by the LED light source 200 and enters the light output channel 700, it is diffusely reflected by the first diffuse reflection plate 300 and the second diffuse reflection plate 500, so that the light distribution is more uniform, so that the light finally emitted to the outside through the lens 400 becomes soft and uniform, not dazzling, and looks particularly beautiful, greatly improving the visual effect.

[0037] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, various modifications and variations can be made to the present invention; any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
