[0034] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 6 The present embodiment provides an optical module 100, comprising a light emitting component 120, a primary optical element 130, a light emitting component 140 and a baffle 111; the primary optical element 130 is arranged on the light emitting side of the light emitting component 120; the baffle 111 is provided with a reflecting surface 112 facing a light incident surface 141 of the light emitting component 140; the light beam emitted by the light emitting component 120 is emitted toward the light incident surface 141 of the light emitting component 140 through the primary optical element 130, and a part of the light beam is emitted through the light emitting component 140 to form a main light shape; another part of the light is reflected from the light incident surface 141 to the reflecting surface 112, and is emitted toward the light emitting component 140 through the reflecting surface 112, and is emitted by the light emitting component 140 to form a three-zone light shape.
[0035] Specifically, Figure 1 As shown, a primary optical element 130 is disposed on the light emitting side of the light emitting component 120 , and the primary optical element 130 can emit the light beam emitted by the light emitting component 120 to the light emitting element 140 .
[0036] The light incident surface 141 of the light emitting element 140 refracts most of the light beams, and the light beams are emitted from the light emitting surface of the light emitting element 140 to form a main light shape; another part of the light beams are reflected from the light incident surface 141 to the baffle 111 through the Fresnel reflection principle, and are reflected again to the light incident surface 141 of the light emitting element 140 through the reflective surface 112 on the baffle 111, and are refracted by the light emitting element 140 and emitted from the light emitting surface of the light emitting element 140 to form a three-zone light shape. Optionally, the reflective surface 112 of the baffle 111 is disposed between the light emitting component 120 and the light emitting element 140 to improve the reflection efficiency.
[0037] Existing lens-type optical modules usually have micro patterns on the surface of the light-emitting element, such as Figure 4 As shown, the light beam emitted by the light emitting component is reflected by the primary optical element and then emitted to the three-zone position through the micro-pattern on the light emitting element to meet the three-zone regulations. However, setting the micro-pattern on the surface of the light emitting element is likely to cause the micro-pattern structure to be uneven, resulting in bright or dark strips in the light, affecting the effect of the three-zone light shape, easily causing dazzle to the driver of the oncoming vehicle, and reducing driving safety.
[0038] In the optical module 100 provided in the present application, after the light beam emitted by the light emitting component 120 is emitted to the light emitting element 140 through the primary optical element 130, part of the light beam is refracted by the light emitting element 140 and emitted to form the main light shape, and a small part of the light beam is reflected to the reflective surface 112 of the baffle 111 through the light incident surface 141, and then reflected again by the reflective surface 112 to the light incident surface 141 of the light emitting element 140, and emitted from the light emitting surface of the light emitting element 140 through the refraction of the light emitting element 140 to form a three-zone light shape. Although the three-zone light shape formed is darker, it can still meet the three-zone regulations, and the darker three zones are not easy to cause glare deductions, and are not easy to illuminate the eyes of drivers of oncoming vehicles when driving on the road, thereby improving driving safety;
[0039] By providing a baffle 111 with a larger surface, the light beams reflected and emitted by the reflective surface 112 on the baffle 111 will not be gathered into a number of brighter light spots, thereby improving the uniformity of the three-zone light shape and further improving driving safety.
[0040] In an implementation manner of the present application, the primary optical element 130 is a reflector; the light emitting element 140 is a double-piece lens, a single-piece lens or other light emitting elements 140 .
[0041] In an implementation manner of the present application, the baffle 111 is disposed on the circuit board 121 of the optical module 100 or the end of the heat dissipation assembly 110 facing the light emitting element 140 .
[0042] In order to ensure that the reflective surface 112 of the baffle 111 can better reflect the light beam, ensure that the light beam reflected by the light emitting element 140 can be reflected again by the reflective surface 112 of the baffle 111, and improve the utilization rate of the light; Figure 2 and Figure 7 , a height H1 from the baffle 111 to the mounting surface of the circuit board 121 is greater than a height H2 of the circuit board 121, that is, a vertical distance from the vertex of the baffle 111 along the first direction a to the mounting surface of the circuit board 121 is greater than a thickness of the circuit board 121 along the first direction a.
[0043] In an implementation manner of the present application, the primary optical element 130 is a light-concentrating element, and the reflective surface 112 of the baffle 111 is disposed between the light-emitting surface of the light-concentrating element and the light-emitting element 140 .
[0044] The optical module 100 provided in the present application includes a light-emitting component 120, a primary optical element 130, a light-emitting element 140 and a baffle 111; the primary optical element 130 is arranged on the light-emitting side of the light-emitting component 120; the baffle 111 is provided with a reflective surface 112 facing the light-entering surface 141 of the light-emitting element 140; the light beam emitted by the light-emitting component 120 is emitted to the light-entering surface 141 of the light-emitting element 140 through the primary optical element 130, and a part of the light beam is emitted through the light-emitting element 140 to form a main light shape; another part of the light is reflected from the light-entering surface 141 to the reflective surface 112, and is emitted to the light-emitting element 140 through the reflective surface 112, and is emitted by the light-emitting element 140 to form a three-zone light shape. Through the above optical module 100, it is possible to meet the three-zone regulations while ensuring the uniformity of lighting, avoid bright or dark strips in the three-zone light shape that cause dazzle to the driver, and improve the driving safety of the driver.
[0045] In one possible implementation of the present application, Figure 2 As shown, the reflective surface 112 is arranged parallel or approximately parallel to the light incident surface 141 of the light emitting element 140 .
[0046] Specifically, please refer to Figure 2 and Figure 5 The reflecting surface 112 of the baffle 111 is parallel or approximately parallel to the light incident surface 141 of the light emitting element 140 and the light incident surface 141 arranged on the light incident surface 141, so as to ensure that the light beam reflected by the light incident surface 141 of the light emitting element 140 can just enter the reflecting surface 112 of the baffle 111, and the light beam can also be just reflected to the light incident surface 141 of the light emitting element 140 through the reflecting surface 112.
[0047] In one possible implementation of the present application, Figure 5 As shown, the reflective surface 112 is provided with a microstructure 1111 .
[0048] Specifically, Figure 5As shown, a microstructure 1111 is convexly provided on the reflective surface 112, so that the uniform light reflective surface 112 is a diffuse reflective surface 112. By setting the microstructure 1111, the uniformity of the light beam can be improved.
[0049] The existing lens-type optical module 100 usually sets the micro-pattern on the surface of the light-emitting element 140, which is not conducive to the beauty of the light-emitting element 140, and it is also difficult to adjust the micro-pattern. Therefore, the brightness or setting position of the three-zone light shape of the existing lens-type optical module 100 is difficult to control. However, the optical module 100 provided in the present application sets the microstructure 1111 on the reflective surface 112 of the baffle 111, which will not affect the appearance of the optical module 100, and is more conducive to adjusting the microstructure 1111, thereby changing the brightness and setting position of the three-zone light shape, thereby improving the flexibility of the three-zone light shape.
[0050] It should be noted that, in the possible implementation modes of the present application, firstly, the optical module 100 provided in the present application can adjust the degree of light beam dispersion of the baffle 111 by adjusting the arch height of the microstructure 1111 protruding on the reflective surface 112, thereby adjusting the brightness of the three-zone light shape;
[0051] Second, the optical module 100 provided in the present application can adjust the upper and lower positions of the three-zone light pattern by increasing or decreasing the draft angle of the baffle 111 .
[0052] Thirdly, the optical module 100 provided in the present application can change the left and right positions of the three-zone light pattern by changing the orientation of the microstructure 1111 protrudingly disposed on the reflective surface 112 .
[0053] Optionally, the microstructure 1111 includes protrusions or stripes uniformly distributed on the reflective surface 112 .
[0054] Specifically, a microstructure 1111 is provided on the reflective surface 112 arranged on the baffle 111, so that the reflective surface 112 is a diffuse reflective surface 112, wherein the microstructure 1111 includes protrusions or stripes evenly distributed on the reflective surface 112. Such a setting method can make the light beam more uniform after being reflected by the reflective surface 112.
[0055] In one possible implementation of the present application, Figure 2 As shown, the optical module 100 also includes: a circuit board 121, a heat dissipation component 110 and a module bracket 150, the light-emitting component 120 is arranged on the circuit board 121, the circuit board 121 is connected to the heat dissipation component 110, and the baffle 111 is arranged on the circuit board 121, the heat dissipation component 110 or the module bracket 150.
[0056] Specifically, the light emitting assembly 120 includes a light source, and the optical module 100 also includes a circuit board 121, a heat dissipation assembly 110, and a module bracket 150. The circuit board 121 is attached to the heat dissipation assembly 110, and the heat dissipation assembly 110 can dissipate heat for the circuit board 121 well to improve the reliability of the circuit board 121. The light source is arranged on the circuit board 121 (not shown in the figure). Optionally, the light source is an LED lamp.
[0057] Another aspect of the present invention provides a vehicle, including an optical module 100 .
[0058] Specifically, the present application also provides a vehicle, which includes the above optical module 100, wherein the specific structure and beneficial effects of the optical module 100 have been described in detail above and will not be repeated here. The above vehicle can meet the three-zone regulations while ensuring the uniformity of lighting when lighting the optical module 100 through the setting of the optical module 100, avoid bright or dark strips in the three-zone light shape that cause dazzle to the driver, and improve the driving safety of the driver.
