[0002] In related technologies, with the development of automotive lighting technology and the diversification of automotive headlight designs, the market has put forward higher requirements for the performance of lighting modules. Existing lighting modules have limited functions, mainly responsible for nighttime road lighting, and cannot realize daytime light functions. Although some lighting modules can still light up after the lighting mode is turned off to improve the hollowness of the high beam area in low beam mode, they cannot realize the scenario where the lighting module is lit up at the same time as the daytime light. Moreover, in order to improve the lighting effect of the daytime light, it is often necessary to add an extra daytime light outside the module, which not only increases the complexity of the overall lamp design, but also leads to an increase in the cost of the entire lamp.

[0022] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0023] The following is for reference. Figures 1-6 The optical module 10 according to an embodiment of the present application is described. The optical module 10 includes a first inner lens 11, a second inner lens 12, and a light-emitting element.

[0024] The first inner lens 11 has a first light-incoming surface 111, a first reflective surface 112, and a first light-exiting surface 113, with the first reflective surface 112 and the first light-exiting surface 113 correspondingly arranged along the length direction of the optical module 10. The second inner lens 12 has a second light-incoming surface 121 and a second light-exiting surface 122, with the second light-incoming surface 121, the second light-exiting surface 122, and the first reflective surface 112 correspondingly arranged along the length direction. Light-emitting elements are respectively arranged corresponding to the first light-incoming surface 111 and the second light-incoming surface 121. The second inner lens 12 can be selectively moved relative to the first inner lens 11 to switch between a first position and a second position. In the first position, the second light-emitting surface 122 and the first reflective surface 112 are spaced apart. The first reflective surface 112 is adapted to reflect the light incident through the first light-incoming surface 111 to the first light-emitting surface 113. In the second position, the second light-emitting surface 122 is in contact with the first reflective surface 112. The light emitted by the light-emitting element passes sequentially through the second light-incoming surface 121, the second light-emitting surface 122 and the first reflective surface 112 and exits from the first light-emitting surface 113.

[0025] Currently, lighting modules have limited functionality, primarily responsible for nighttime road lighting and unable to function as daytime lights. While some lighting modules can still illuminate after the lighting mode is turned off to improve the hollowness of the high beam area in low beam mode, they still cannot achieve the scenario where the lighting module is lit simultaneously with the daytime lights. Moreover, to improve the lighting effect of daytime lights, it is often necessary to add additional daytime lights outside the module, which not only increases the complexity of the overall lamp design but also leads to an increase in the overall lamp cost.

[0026] Specifically, the optical module 10 includes a first inner lens 11, a second inner lens 12, and a light-emitting element. The first inner lens 11 may have a first light-incoming surface 111, a first reflective surface 112, and a first light-emitting surface 113. Light is incident from the first light-incoming surface 111 to the first reflective surface 112, reflected by the first reflective surface 112, and emitted from the first light-emitting surface 113, thereby realizing the low beam, high beam, or high-low beam functions of the optical module 10. In some embodiments, the first inner lens 11 can be a low beam lens to realize the low beam function of the optical module 10; or, the first inner lens 11 can be a high beam lens to realize the high beam function of the optical module 10; or, the first inner lens 11 can be a low beam lens and a high beam lens connected in sequence to realize the high-low beam function of the optical module 10. The first reflective surface 112 and the first light-emitting surface 113 are along the length direction of the optical module 10 (e.g., along the length direction of the optical module 10). Figure 1 The X direction shown in the figure corresponds to the setting.

[0027] The second inner lens 12 may have a second light-inlet surface 121 and a second light-outlet surface 122. The second light-inlet surface 121, the second light-outlet surface 122 and the first reflective surface 112 may be arranged correspondingly along the length direction. The second inner lens 12 may be a daylight lamp lens, that is, to realize the function of a daylight lamp. The light-emitting element may be arranged correspondingly to the first light-inlet surface 111 and the second light-inlet surface 121 respectively. There may be multiple light-emitting elements, and the light-emitting elements may emit light to provide a light source for the optical module 10.

[0028] Furthermore, the second inner lens 12 can selectively move relative to the first inner lens 11, thereby switching between a first position and a second position. In the first position, the second light-emitting surface 122 is spaced apart from the first reflective surface 112, and in the second position, the second light-emitting surface 122 is in contact with the first reflective surface 112. It should be noted that when the second light-emitting surface 122 and the first reflective surface 112 are spaced apart, that is, when there is air between the second light-emitting surface 122 and the first reflective surface 112, total internal reflection can occur when light shines on the first reflective surface 112 at a certain angle. The light can be reflected by the first reflective surface 112 to the first light-emitting surface 113, thereby realizing the illumination function of the optical module 10. When the second light-emitting surface 122 is in contact with the first emitting surface, that is, there is no air between the second light-emitting surface 122 and the first emitting surface, the light emitted by the light-emitting element can pass through the second light-incoming surface 121, the second light-emitting surface 122 and the first reflective surface 112 in sequence and exit from the first light-emitting surface 113, thereby realizing the daytime lamp function of the optical module 10. It can be seen that by adopting the above method, the optical module 10 can switch between the lighting mode and the daytime lamp mode without interfering with each other. Compared with the prior art, the functions are increased, the cost of the vehicle lamp is reduced, and the styling flexibility of the overall lighting effect can be improved.

[0029] In short, the optical module 10 of this application embodiment has a first inner lens 11 and a second inner lens 12. The second inner lens 12 can selectively move relative to the first inner lens 11 to switch between a first position and a second position. In the first position, the second light-emitting surface 122 and the first reflective surface 112 are spaced apart, and light shines from the first inner lens 11 to the outside to realize the illumination function of the optical module 10. In the second position, the second light-emitting surface 122 is attached to the first reflective surface 112, and light shines from the second inner lens 12 and the first inner lens 11 to the outside to realize the daytime lamp function of the optical module 10. Therefore, the optical module 10 can independently satisfy both the illumination function and the daytime lamp function, realizing the multi-functionality of the optical module 10 and reducing the cost of vehicle lights.

[0030] like Figure 3 and Figure 4As shown, in some embodiments of this application, in the first position, the shortest distance between the second light-emitting surface 122 and the first reflective surface 112 is L, satisfying the relationship: 0.2mm≤L≤0.4mm. That is, in the first position, the shortest distance between the second light-emitting surface 122 and the first reflective surface 112 can be any value between 0.2mm and 0.4mm. For example, in the first position, the shortest distance between the second light-emitting surface 122 and the first reflective surface 112 can be, but is not limited to, 0.2mm, 0.25mm, or 0.4mm. 3mm, 0.35mm, 0.4mm, etc. If the shortest distance between the second light-emitting surface 122 and the first reflective surface 112 is too large, it will cause the size of the optical module 10 in the length direction to increase, resulting in an increase in the space it occupies. If the shortest distance between the second light-emitting surface 122 and the first reflective surface 112 is too small, it will affect the total internal reflection effect of the first reflective surface 112. Therefore, by setting the shortest distance between the second light-emitting surface 122 and the first reflective surface 112 within the above range, the reliability of the illumination function of the optical module 10 can be improved.

[0031] like Figure 3 As shown, in some embodiments of this application, the first inner lens 11 further has a second reflecting surface 114 and a third reflecting surface 115. The second reflecting surface 114 can be aligned with the first light-incoming surface 111 along the height direction of the optical module 10 (e.g., ...). Figure 3 The third reflective surface 115 and the second reflective surface 114 are arranged in the same direction along the length. That is, when the light-emitting element emits light to the first light-incoming surface 111, the light is first reflected by the second reflective surface 114 to the third reflective surface 115, and then reflected by the third reflective surface 115 to the first reflective surface 112, thereby improving the output efficiency and brightness of the light.

[0032] like Figure 1 and Figure 2 As shown, in some embodiments of this application, the light-emitting element may include a first light-emitting particle 13 and a second light-emitting particle 14. The first light-emitting particle 13 and the second light-emitting particle 14 may be LED particles. The first light-emitting particle 13 may be correspondingly arranged with the first light-receiving surface 111, and the second light-emitting particle 14 may be correspondingly arranged with the second light-receiving surface 121. The first light-emitting particle 13 may emit light to the first light-receiving surface 111. When the second inner lens 12 is in the first position, the optical module 10 can realize the illumination function. The second light-emitting particle 14 may emit light to the second light-receiving surface 121. When the second inner lens 12 is in the second position, the optical module 10 can realize the daytime lamp function.

[0033] like Figure 1 and Figure 2As shown, in some embodiments of this application, the second inner lens 12 is further provided with a condenser 123. The light inlet of the condenser 123 can be correspondingly arranged with the second light inlet surface 121, and the light outlet of the condenser 123 can face the second light outlet surface 122. The condenser 123 can converge the light emitted by the second light-emitting particle 14, increase the light intensity and control the irradiation direction, so that it irradiates the second light outlet surface 122, reduce light scattering and improve the lighting effect. Furthermore, the light inlet of the condenser 123 has a pattern, so that the light diffuses left and right.

[0034] like Figure 1 and Figure 2 As shown, in some embodiments of this application, the number of first light-emitting particles 13 can be multiple, and the multiple first light-emitting particles 13 can be along the width direction of the optical module 10 (e.g., ...). Figure 2 The second light-emitting particles 14 are spaced apart in the Y direction shown. There can be multiple second light-emitting particles 14. The multiple second light-emitting particles 14 are spaced apart along the width direction of the optical module 10, and each second light-emitting particle 14 corresponds to the light inlet of a condenser 123. By setting multiple first light-emitting particles 13 and multiple second light-emitting particles 14, the light intensity can be further improved to realize the illumination function and daylight function of the optical module 10.

[0035] In some embodiments of this application, the optical module 10 further includes a driving structure, which can be connected to the second inner lens 12 via a transmission mechanism. The driving structure can be used to drive the second inner lens 12 to move relative to the first inner lens 11. Optionally, the driving structure can be a motor, which can be connected to the second inner lens 12 via a transmission component. The transmission component can be a worm gear or a gear set. The motor can drive the second inner lens 12 to move by working. Alternatively, the driving structure can also be constructed as a spring and a cylinder. The cylinder can drive the second inner lens 12 to move in one direction, and the spring can play a restoring role to reset the second inner lens 12.

[0036] In some embodiments of this application, the first inner lens 11 is made of polycarbonate and the second inner lens 12 is made of silicone. That is, the hardness of the first inner lens 11 is greater than that of the second inner lens 12. This arrangement allows the second inner lens 12 to fit better with the first inner lens 11, ensuring that there is no large amount of air between the first inner lens 11 and the second inner lens 12, achieving a gapless fit, and ensuring that light can be sequentially irradiated to the outside through the second inner lens 12 and the first inner lens 11 to realize the daytime lamp function of the optical module 10.

[0037] The following describes the vehicle lights according to embodiments of this application.

[0038] The vehicle lamp according to the embodiment of this application is provided with the optical module 10 of the above embodiment. Since the vehicle lamp of the embodiment of this application is provided with the optical module 10 of the above embodiment, the optical module 10 of the vehicle lamp has a first inner lens 11 and a second inner lens 12. The second inner lens 12 can selectively move relative to the first inner lens 11 to realize the switching of the second inner lens 12 between a first position and a second position. In the first position, the second light-emitting surface 122 and the first reflective surface 112 are spaced apart, and light shines from the first inner lens 11 to the outside to realize the illumination function of the optical module 10. In the second position, the second light-emitting surface 122 is attached to the first reflective surface 112, and light shines from the second inner lens 12 and the first inner lens 11 to the outside to realize the daytime lamp function of the optical module 10. The optical module 10 of the vehicle lamp can independently satisfy the illumination function and independently satisfy the daytime lamp function, realizing the multi-functionality of the optical module 10 and reducing the cost of the vehicle lamp.
