[0033] Please refer to Figure 1 This embodiment provides an optical component 100. The optical component 100 includes a reflective optical element 120, and the reflective optical element 120 includes a plurality of reflective optical surface groups, which are arranged at different positions of the reflective optical element 120. The light beams emitted by the light source 110 are respectively reflected by the plurality of reflective optical surface groups and emitted toward different angles, and the light beams reflected by the respective reflective optical surface groups respectively meet the brightness requirements of different angle ranges of the irradiation area.
[0034] By such a setting, the light source 110 is emitted at different angles after being incident on a plurality of reflective optical surface groups at different positions, which can meet the regulatory requirements. At the same time, when the reflective optical surface groups at different positions respectively reflect the light source 110, the lighting effect of the reflective optical element 120 is good. The vehicle lights of the present application can be signal lights, fog lights or vehicle lights with other functions. Since the regulatory requirements for rear fog lights are extremely stringent, the lighting effect of the rear fog lights will be abandoned in order to meet the regulations when designing the rear fog lights of existing automobiles. Therefore, the present application is particularly suitable for rear fog lights, but the present application is not limited thereto.
[0035] In one possible implementation of the present application, Figure 2 and Figure 3 As shown, the reflective optical surface group includes a first reflective optical surface group 121 and / or a second reflective optical surface group 122. The light beams reflected by the first reflective optical surface group 121 and / or the second reflective optical surface group 122 meet the brightness requirements of the irradiated area within a set angle range in the gravity direction a.
[0036] Specifically, the light source 110 emits a light beam toward the first reflective optical surface group 121 and / or the second reflective optical surface group 122. When the light source 110 emits a light beam that impinges on the first reflective optical surface group 121 and / or the second reflective optical surface group 122, under normal circumstances, the emitted light beam is collimated and emitted with a certain diffusion angle. However, in order to meet the regulations of the optical component 100, it is necessary to deflect the emission direction of the light beam by a certain angle along the gravity direction a.
[0037] In a preferred embodiment of the present application, the reflective optical element 120 has a reference reflective surface with the light source 110 as the focus, and the first reflective surface of the first reflective optical surface group 121 and the second reflective surface of the second reflective optical surface group 122 are deflected at a set angle toward / backward of the gravity direction a based on the reference reflective surface to meet the brightness requirements within the set angle range.
[0038] For example, the first reflective optical surface group 121 includes a plurality of first reflective surfaces, and the first reflective surfaces of the first reflective optical surface group 121 are deflected 4 to 6 degrees toward the gravity direction a based on the reference reflective surface to meet the brightness requirement of the lower 5-degree regulation point. The second reflective optical surface group 122 includes a plurality of second reflective surfaces, and the second reflective surfaces of the second reflective optical surface group 122 are deflected by a rotation angle of -4 to -6 degrees toward the gravity direction a based on the reference reflective surface (that is, deflected 4 to 6 degrees away from the gravity direction a based on the reference reflective surface) to meet the brightness requirement of the upper 5-degree regulation point.
[0039] In one possible implementation of the present application, Figure 3 As shown, the first reflective optical surface group 121 and the second reflective optical surface group 122 are relatively arranged on both sides of the reflective optical element 120 in the gravity direction a. Preferably, the first reflective optical surface group 121 is located at the upper part of the reflective optical element 120, so that when deflected toward the gravity direction a, the emitted light beam can cover the middle area to improve the lighting effect. Preferably, the second reflective optical surface group 122 is located at the lower part of the reflective optical element 120, so that when deflected away from the gravity direction a, the emitted light beam can cover the middle area to improve the lighting effect.
[0040] In a preferred solution of the present application, the first reflective optical surface group 121 and / or the second reflective optical surface group 122 are at least partially blocked by the car bezel 200 to make the lighting effect more beautiful.
[0041] In one possible implementation of the present application, Figure 4 and 5 As shown, the reflective optical surface group includes a third reflective optical surface group 123 and / or a fourth reflective optical surface group 124. The light beams reflected by the third reflective optical surface group 123 and / or the fourth reflective optical surface group 124 meet the brightness requirements of the irradiated area within a set angle range in the horizontal direction b, and the horizontal direction b is perpendicular to the gravity direction a.
[0042] In a preferred embodiment of the present application, the reflective optical element 120 has a reference reflective surface with the light source 110 as the focus, and the third reflective surface of the third reflective optical surface group 123 and the fourth reflective surface of the fourth reflective optical surface group 124 are deflected at a set angle toward / backward of the horizontal direction b based on the reference reflective surface to meet the brightness requirements within the set angle range.
[0043] For example, the third reflective optical surface group 123 includes a plurality of third reflective surfaces, and the fourth reflective surface of the fourth reflective optical surface group 124 is deflected by 9 to 11 degrees toward the horizontal direction b based on the reference reflective surface to meet the brightness requirement of the inner 10-degree regulation point. The fourth reflective optical surface group 124 includes a plurality of fourth reflective surfaces, and the fourth reflective surface of the fourth reflective optical surface group 124 is deflected by a rotation angle of -9 to -10 degrees toward the horizontal direction b based on the reference reflective surface (that is, deflected by 9 to 10 degrees away from the horizontal direction b based on the reference reflective surface) to meet the brightness requirement of the outer 10-degree regulation point.
[0044] In one possible implementation of the present application, Figure 5 As shown, the third reflective optical surface group 123 and the fourth reflective optical surface group 124 are arranged in the middle area of the reflective optical element 120 in the gravity direction a.
[0045] Specifically, since the third reflective optical surface group 123 and the fourth reflective optical surface group 124 are used to meet the brightness requirements of the illumination area within a set angle range in the horizontal direction b, the third reflective optical surface group 123 and the fourth reflective optical surface group 124 are arranged in the middle area of the reflective optical element 120 in the gravity direction a, so as to be located between the first reflective optical surface group 121 and the second reflective optical surface group 122, so as to further improve the aesthetics of the optical component 100 when it is lit.
[0046] Preferably, the third reflective surface of the third reflective optical surface group 123 and the fourth reflective surface of the fourth reflective optical surface group 124 are arranged alternately to obtain a chessboard-patterned lighting effect.
[0047] Furthermore, the reflective optical element 120 may further include a fifth reflective optical surface group 125, wherein the fifth reflective surface of the fifth reflective optical surface group 125 is located between a third reflective surface and a fourth reflective surface, so that any two opposite sides of the fifth reflective surface are the third reflective surface and the fourth reflective surface. The fifth reflective optical surface may be a collimated reflective optical surface, which can ensure that the light beam emitted by the light source 110 is collimated and diffused, thereby meeting other regulatory requirements of the optical component 100.
[0048] Another aspect of the present invention provides a vehicle lamp, which includes the above optical assembly 100 and the light source 110, so as to obtain the same beneficial effects as the above optical assembly 100. The specific structure of the optical assembly 100 has been described in detail above and will not be repeated here.
[0049] The above description is only an optional embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
[0050] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present utility model will not further describe various possible combinations.
