[0032] Please refer to Figure 1 and Figure 2 , this embodiment provides an optical component 100, which includes an array light source 110 and a light output component 120 arranged on the light output side of the array light source 110; the light output component 120 includes a light distribution lens 121 and a light shielding member 122, and the light shielding member 122 is attached to the side of the light distribution lens 121 facing away from the array light source 110; the light shielding member 122 includes a plurality of light transmission holes 1221 arranged in an array, the array light source 110 includes a plurality of light emitting units arranged in an array, and the light emitting units are arranged corresponding to the light transmission holes 1221; the light beam emitted by the array light source 110 enters the light distribution lens 121 and exits through the light transmission holes 1221 of the light shielding member 122.

[0033] Specifically, as Figure 1 and Figure 2As shown, the optical component 100 includes an array light source 110, which includes a plurality of light-emitting units arranged in an array for emitting light beams. On the light-emitting side of the array light source 110, there is a light-emitting component 120, which includes a light distribution lens 121 and a light-shielding member 122. The light distribution lens 121 is used to gather the light beams emitted by the array light source 110. On the side of the light distribution lens 121 facing away from the array light source 110, there is a positioning groove, and the light-shielding member 122 is positioned and installed on the light distribution lens 121 through the positioning groove. The light-shielding member 122 is provided with a plurality of light-transmitting holes 1221 arranged in an array, and the light-transmitting holes 1221 are arranged corresponding to the light-emitting units. The light beams emitted by the array light source 110 enter the light distribution lens 121 and then exit through the light-transmitting holes 1221 of the light-shielding member 122. Optionally, the array light source 110 is an LED light source.

[0034] Since the light-shielding member 122 itself is light-impermeable, it can provide a good light-blocking effect on the light beams emitted by adjacent array light sources 110, avoiding the light leakage of the light beams emitted by adjacent array light sources 110. In existing vehicle-mounted signal lights, adjacent vertically arranged LED light sources are prone to light leakage. Therefore, in order to solve the problem of light leakage, the existing vehicle-mounted signal lights usually increase the interval of the light-emitting holes, reducing the overall aesthetics and display effect. However, the optical component 100 provided in this application solves the problem of light leakage of the light beams emitted by adjacent light-emitting units without changing the light-emitting interval, improving the overall lighting effect of the optical component 100.

[0035] It should be noted that in the feasible embodiments of this application, first, in order to protect the optical component 100 and the vehicle as a whole and avoid the light-shielding member 122 from causing crushing to the optical component 100 or the exterior trim 220 of the vehicle, the light-shielding member 122 is made of a flexible buffer material.

[0036] Second, as Figure 4 shown, in a specific embodiment of this application, the light-transmitting holes 1221 of the light-shielding member 122 are triangular holes. Of course, this application does not impose any restrictions on the specific shape of the light-transmitting holes 1221, and the light-transmitting holes 1221 can also be other shapes such as circular or square, as long as it can ensure that the light beams exit through the light-transmitting holes 1221 of the light-shielding member 122.

[0037] Third, the setting positions of the light-emitting units correspond to the light-transmitting holes 1221. In one embodiment of this application, one light-transmitting hole 1221 is correspondingly provided with one light-emitting unit; in another embodiment of this application, one light-transmitting hole 1221 can also correspond to multiple light-emitting units. For example, one light-transmitting hole 1221 is correspondingly provided with two light-emitting units, and the two light-emitting units can emit light beams of different colors, further improving the overall lighting effect of the optical component 100.

[0038] This application provides an optical component 100, which includes an array light source 110 and a light-emitting component 120 disposed on the light-emitting side of the array light source 110; the light-emitting component 120 includes a light distribution lens 121 and a light-shielding member 122, and the light-shielding member 122 is attached to the side of the light distribution lens 121 facing away from the array light source 110; the light-shielding member 122 includes a plurality of light-transmitting holes 1221 arranged in an array, the array light source 110 includes a plurality of light-emitting units arranged in an array, and the light-emitting units are correspondingly arranged with the light-transmitting holes 1221; the light beams emitted by the array light source 110 are incident on the light distribution lens 121 and emitted through the light-transmitting holes 1221 of the light-shielding member 122. The light-transmitting holes 1221 of the light-shielding member 122 can separate the light beams emitted by each light-emitting unit, avoiding the light leakage of the light beams emitted by adjacent light-emitting units. Even if the distance between adjacent light-emitting units is relatively close, it will not affect the contrast between the light-emitting units. Thus, the pixel contrast and display resolution of the vehicle-mounted lamp 200 are improved, and further the display effect of the vehicle-mounted lamp 200 is improved.

[0039] In an implementable manner of this application, as Figure 1 shown, the optical component 100 further includes a light guide 130, the light guide 130 is disposed on the light-emitting side of the array light source 110 and is attached to the side of the light-emitting component 120 close to the array light source 110; the light guide 130 includes a plurality of light channels 131 arranged in an array, and the light channels 131 are correspondingly arranged with the light-emitting units; the light beams emitted by the array light source 110 are incident on the light distribution lens 121 through the light channels 131 of the light guide 130 and are emitted through the light-transmitting holes 1221 of the light-shielding member 122.

[0040] Specifically, a light guide 130 is further disposed on the light-emitting side of the array light source 110, and positioning pins are disposed on the side of the light distribution lens 121 facing the array light source 110. The light guide 130 can be positioned and installed with the light distribution lens 121 through the positioning pins. A plurality of light channels 131 arranged in an array are provided on the light guide 130, and the light channels 131 are respectively correspondingly arranged with the light-emitting units and the light-transmitting holes 1221. The light beams emitted by the array light source 110 are incident on the light distribution lens 121 through the light channels 131 of the light guide 130 and are emitted through the light-transmitting holes 1221 of the light-shielding member 122. Through the arrangement of the light guide 130, the light channels 131 can collect and transmit the light beams emitted by the light-emitting units. As Figure 1 shown, the light channel 131 has a trapezoidal structure, and the aperture on the side close to the array light source 110 is smaller than the aperture on the side close to the light distribution lens 121. The light channel 131 can effectively guide and diffuse the light beams emitted by the light-emitting units, making the light rays emitted by the optical component 100 more uniform and improving the lighting effect.

[0041] It should be noted that in order to improve the utilization rate of light and ensure that more light enters the light-transmitting hole 1221 through the light channel 131 by the light distribution mirror 121, the aperture of the light-transmitting hole 1221 on the side close to the light distribution mirror 121 is larger than the aperture of the light channel 131 on the side close to the array light source 110.

[0042] Optionally, the aperture of the light-transmitting hole 1221 on the side of the light-shielding member 122 close to the light distribution mirror 121 is 0.3 - 2 mm larger than the aperture of the light channel 131 of the light guide member 130 on the side close to the array light source 110.

[0043] On the other hand, an embodiment of the present application provides a vehicle-mounted lamp 200, including an exterior trim member 220 and an optical component 100. The light-shielding member 122 of the optical component 100 is disposed between the light distribution mirror 121 of the optical component 100 and the exterior trim member 220, and both sides of the light-shielding member 122 are respectively attached to the light distribution mirror 121 and the exterior trim member 220; the exterior trim member 220 is a light-transmitting member, and the light beam emitted by the array light source 110 of the optical component 100 is incident into the light-transmitting hole of the light-shielding member 122 through the light distribution mirror 121 and is emitted by the exterior trim member 220.

[0044] Specifically, the present application also provides a vehicle-mounted lamp 200, which includes an exterior trim member 220. In order to ensure that the light beam emitted by the vehicle-mounted lamp 200 can be emitted by the exterior trim member 220, the exterior lamp is a light-transmitting member. It also includes a housing 210, and the optical component 100 can be partially installed in the housing 210; as Figure 3 shown, the light-shielding member 122 is disposed between the light distribution mirror 121 and the exterior trim member 220 of the vehicle-mounted lamp 200, and both sides of the light-shielding member 122 are respectively attached to the light-shielding member 122 and the exterior trim member 220, which can fill the gap between the vehicle-mounted lamp 200 and the exterior trim member 220, play a role in sealing and light shielding, avoid the light beam crosstalk of adjacent array light sources 110 in the vehicle-mounted lamp 200, make the contrast of the lit pattern higher, and the shape of the graphic lighting more distinct; at the same time, it can also play a role in waterproofing and dustproofing, improving the driving reliability. Among them, the specific structure and beneficial effects of the optical component 100 have been introduced in detail above and will not be elaborated here.

[0045] It should be noted that in order to ensure that the gap between the light distribution mirror 121 and the exterior trim member 220 is filled by the light-shielding member 122 and effectively improve the light-shielding effect of the light-shielding member 122, preferably, the thickness of the light-shielding member 122 is 1 - 2 times the width of the gap between the exterior trim member 220 and the light distribution mirror 121.

[0046] Second, the vehicle-mounted lamp 200 provided by the present application can be a vehicle-mounted signal lamp, or other exterior lamps or interior lamps, and the present application does not make any limitation on the specific setting form of the vehicle-mounted lamp 200.

[0047] In an implementable embodiment of the present application, the exterior trim member 220 includes a plurality of light-transmitting regions arranged in an array. The light-transmitting regions are correspondingly arranged with the light-transmitting holes 1221 of the light-shielding member 122. The light beams emitted by the array light source 110 are incident into the light-transmitting holes 1221 of the light-shielding member 122 through the light distribution lens 121 and are emitted from the light-transmitting regions of the exterior trim member 220.

[0048] Specifically, the exterior trim member 220 includes a plurality of light-transmitting regions arranged in an array. In a specific embodiment of the present application, the outer wall of the exterior trim member 220 is coated with vehicle body paint, and the region coated with vehicle body paint is a non-light-transmitting region; the light-transmitting regions of the exterior trim member 220 are correspondingly arranged with the light-transmitting holes 1221 of the light-shielding member 122. Therefore, the light beams emitted by the vehicle-mounted lamp 200 can be emitted from the light-transmitting regions of the exterior trim member 220. Such a setting method improves the aesthetics of the vehicle while ensuring the light-transmitting property of the exterior trim member 220, making the light beam boundary clearer when the vehicle-mounted lamp 200 is lit and the graphic lighting shape more definite.

The vehicle-mounted lamp 200 of the above vehicle can avoid the light leakage of the light beams emitted by adjacent light-emitting units, improving the reliability and aesthetics of signal interaction of the vehicle through the vehicle-mounted lamp 200. Among them, the specific structure and beneficial effects of the vehicle-mounted lamp 200 have been described in detail above and will not be elaborated here.
