Description

Optical module, optical system and vehicle light Technical Field

[0001] The present application relates to the technical field of vehicle lamps, and in particular to an optical module, an optical system and a vehicle lamp. Background Art

[0002] Headlights are the lighting tools that vehicles use when driving on the road at night. They also serve as a warning tool for various vehicle driving signals and play a very important role in ensuring the safe driving of vehicles. With the continuous development of automotive lighting technology, more requirements have been put forward for the functions of headlights.

[0003] In automotive lighting, low-beam lighting requires a horizontal cutoff line to avoid dazzling other drivers on the road and compromising driving safety. Existing technologies typically use a reflector as a primary optical component, utilizing the reflective surface boundary to form a cutoff structure to achieve the low-beam cutoff line. However, the reflector must first be prefabricated into a reflective body, and then a reflective film is formed on the body's surface through a coating process using materials such as aluminum and silver. This results in high production costs, high energy consumption, and a significant impact on production cycle times. The coating process itself can also cause environmental pollution and lead to defects such as waste due to a high rate of coating failure.

DETAILED DESCRIPTION

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0033] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0034] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0035] It should be noted that, in the description of the embodiments of the present invention, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0036] Referring to Figures 1, 2, and 3, this embodiment provides an optical module 111, comprising a first light source 1111, a primary optical element 1112, and a light-emitting lens 112, arranged sequentially along the optical transmission direction. The primary optical element 1112 is transparent and includes a light-incident surface 1112a, a total reflection surface 1112c, and a first light-emitting surface 1112d. A cutoff line structure is provided at the boundary of the total reflection surface 1112c near the light-incident surface 1112a. Light emitted by the first light source 1111 enters the light-incident surface 1112a of the primary optical element 1112, is reflected by the total reflection surface 1112c, and then is emitted from the first light-emitting surface 1112d. After passing through the light-emitting lens 112, it is projected onto a target plane to form a low-beam light pattern with a bright / dark cutoff line. It should be noted that the target plane may be a vertical plane located 25 meters in front of the vehicle.

[0037] Specifically, light emitted by the first light source 1111 enters the primary optical element 1112 through the light incident surface 1112a, is intercepted by the cutoff structure, and is reflected by the total reflection surface 1112c before exiting through the first light exiting surface 1112d. The primary optical element 1112 is processed into a transparent member having the total reflection surface 1112c, the light incident surface 1112a, and the first light exiting surface 1112d. The total reflection surface 1112c near the boundary of the light incident surface 1112a serves as a cutoff structure. This allows light to enter the primary optical element 1112 through the light incident surface 1112a, be intercepted by the cutoff structure, and then be reflected by the total reflection surface 1112c before exiting through the first light exiting surface 1112d. Finally, after passing through the light exiting lens 112, the light is projected onto the target plane to form a low-beam light pattern with a bright and dark cutoff line. The total reflection surface 1112c can cause the incident light to undergo total reflection, thereby reducing light loss. Total internal reflection refers to the phenomenon in which light, when striking the interface between two media, is reflected without refraction. When light travels from a denser medium to a less dense medium, the angle of refraction is greater than the angle of incidence. When the angle of incidence reaches a certain value, the angle of refraction reaches 90°, at which point no light is refracted in the less dense medium. As long as the angle of incidence is greater than or equal to this value, refraction ceases. This application utilizes total internal reflection to cause light traveling to the total reflection surface 1112c to undergo total reflection before exiting through the first light-emitting surface 1112d, minimizing light loss.

[0038] The optical module 111 provided in the present application includes a first light source 1111 and a primary optical element 1112 and a light-emitting lens 112 arranged in sequence along the transmission direction of the light path. The primary optical element 1112 is a transparent component. The primary optical element 1112 includes a light incident surface 1112a, a total reflection surface 1112c and a first light-emitting surface 1112d. The cutoff line structure is arranged at the boundary of the total reflection surface 1112c close to the light incident surface 1112a. The light emitted by the first light source 1111 is incident on the light incident surface 1112a of the primary optical element 1112, intercepted by the cutoff line structure and reflected by the total reflection surface 1112c, and then emitted from the first light-emitting surface 1112d. After passing through the light-emitting lens 112, it is projected onto the target plane to form a low-beam light type with a bright and dark cutoff line. The optical module 111 provided in the present application uses a transparent member as the primary optical element 1112 and utilizes the boundary of the total reflection surface 1112c to form a cutoff line structure, thereby simplifying the structure of the optical module 111, eliminating the need for a reflective mirror that requires coating, and saving production costs.

[0039] In a feasible embodiment of the present application, as shown in FIG1 , the total reflection surface 1112 c is a parabolic reflection surface or a quasi-parabolic reflection surface.

[0040] Specifically, the total reflection surface 1112c is set to a parabolic reflection surface or a quasi-parabolic reflection surface, so that the total reflection surface 1112c can converge the divergent light emitted by the light source, and the light reflected from the total reflection surface 1112c is parallel light or approximately parallel light, so as to reduce the size of the incident surface of the light-emitting lens 112 corresponding to the primary optical element 1112. Without a large light-emitting lens 112, it is possible to ensure that as much light as possible emitted by the primary optical element 1112 can enter the light-emitting lens 112 through the incident surface of the light-emitting lens 112, thereby reducing the loss of light and ensuring the light effect.

[0041] It should be noted that in the context of this application, when the term "paraboloid" is used, it should be understood to refer to a surface shape close to that of a parabola and having similar optical characteristics to a parabola. For example, similar to a parabola-shaped reflective surface, when a parabola-shaped reflective surface is used as a reflective surface, light emitted from a light source located at or near the focus of the parabola-shaped reflective surface can be emitted in a substantially parallel manner after being reflected by the parabola-shaped reflective surface.

[0042] In one possible embodiment of the present application, as shown in Figures 4 to 7, the optical module 111 further includes a second light source 1113, and the primary optical element 1112 further includes a guide surface 1112e for receiving light emitted by the second light source 1113. Light emitted from the second light source 1113 enters the primary optical element 1112 through the guide surface 1112e, exits from the first light-emitting surface 1112d of the primary optical element 1112, and then exits through the light-emitting lens 112. One end of the guide surface 1112e is connected to the total reflection surface 1112c via a connecting surface 1112b, and the other end of the guide surface 1112e is connected to the light-incident surface 1112a.

[0043] Both the first light source 1111 and the second light source 1113 can be configured as LED light sources, which have gradually become a primary feature of the automotive lamp 100. As a cold light source, LED light sources have a lower temperature, which reduces energy loss during light transmission between the first light source 1111 and the second light source 1113, thereby extending the service life of the first light source 1111 and the second light source 1113. Depending on the application scenario, the colors of the first light source 1111 and the second light source 1113 can be set to suit different needs. For example, the first light source 1111 and the second light source 1113 can be white, yellow, or even a color-changing light source.

[0044] In addition, the second light source 1113 can be used in high-beam lighting scenarios as a high-beam light source, and can also be used in vehicle signal lights as a signal light source. The optical module 111 can realize the multiplexing of headlights and signal lights.

[0045] In a feasible embodiment of the present application, as shown in Figures 4 and 5, the guide surface 1112e is located on the side of the first light-emitting surface 1112d away from the light-emitting lens 112, and the second light source 1113 is arranged corresponding to the guide surface 1112e. The light emitted by the second light source 1113 is incident on the primary optical element 1112 through the guide surface 1112e and is transmitted to the first light-emitting surface 1112d for exit.

[0046] The guide surface 1112e can be configured as a curved surface to converge light, converging the divergent light emitted by the second light source 1113 to ensure that more light enters the primary optical element 1112 and reaches the first light-emitting surface 1112d, thereby reducing light loss and ensuring light efficiency. Furthermore, after the light is converged, a large first light-emitting surface 1112d and a corresponding light-emitting lens 112 are no longer required, and the maximum amount of light emitted from the first light-emitting surface 1112d can be incident on the light-emitting lens 112.

[0047] In a feasible embodiment of the present application, as shown in Figures 6 and 7, the guiding surface 1112e includes an auxiliary light incident surface 1112e1 and an auxiliary reflection surface 1112e2. The auxiliary light incident surface 1112e1 and the light incident surface 1112a are located on the same side, and the auxiliary reflection surface 1112e2 is arranged on the side of the first light output surface 1112d away from the light output lens 112. There is an angle between the auxiliary light incident surface 1112e1 and the auxiliary reflection surface 1112e2, so that the light can reach the auxiliary reflection surface 1112e2 and be reflected after passing through the auxiliary light incident surface 1112e1. The light emitted by the second light source 1113 enters the primary optical element 1112 through the auxiliary light incident surface 1112e1, and is reflected by the auxiliary reflection surface 1112e2 and then emitted from the first light output surface 1112d.

[0048] Specifically, the light emitted by the second light source 1113 enters the primary optical element 1112 through the auxiliary light incident surface 1112e1, and the auxiliary reflection surface 1112e2 is set as a total reflection surface. Using the total reflection phenomenon, the light incident on the auxiliary reflection surface 1112e2 will undergo total reflection and then be transmitted to the first light output surface 1112d for output, thereby reducing light loss.

[0049] Furthermore, one end of the auxiliary reflection surface 1112e2 is connected to the auxiliary light incident surface 1112e1, and the other end of the auxiliary reflection surface 1112e2 is connected to the end of the connecting surface 1112b away from the total reflection surface 1112c. The auxiliary light incident surface 1112e1 is connected to the light incident surface 1112a and is located on the same plane.

[0050] When the second light source 1113 emits light and is used for high beam lighting, the high beam light pattern projected onto the target plane is shown in FIG9 . When the first light source 1111 and the second light source 1113 emit light at the same time, the superimposed high and low beam light pattern projected onto the target plane is shown in FIG10 .

[0051] In a feasible embodiment of the present application, as shown in FIG7 , the auxiliary reflecting surface 1112e2 is a parabolic reflecting surface or a quasi-parabolic reflecting surface.

[0052] Specifically, the light emitted by the second light source 1113 enters the primary optical element 1112 through the auxiliary light incident surface 1112e1, is reflected by the auxiliary reflecting surface 1112e2, and then is emitted through the first light emitting surface 1112d. The auxiliary reflecting surface 1112e2 is a parabolic reflecting surface or a quasi-parabolic reflecting surface. The parabolic reflecting surface or the quasi-parabolic reflecting surface converges the divergent light emitted by the second light source 1113 into parallel light or approximately parallel light to ensure the convergence degree of the emitted light and increase the light energy of the high beam type formed on the target plane after the light passes through the light emitting lens 112. In addition, after the light is converged, there is no need for a large-sized first light emitting surface 1112d and a corresponding light emitting lens 112, so that as much light as possible can be incident on the light emitting lens 112, thereby ensuring the light effect.

[0053] Furthermore, the curvature of the longitudinal section of the auxiliary reflection surface 1112e2 is set to be consistent with the curvature of the longitudinal section of the total reflection surface 1112c. When the first light source 1111 and the second light source 1113 emit light at the same time, the light reflected from the total reflection surface 1112c and the auxiliary reflection surface 1112e2 will not interfere with each other, and the superimposed light patterns of high and low beams are naturally connected at the connection point of the light patterns (as shown in Figure 10).

[0054] In a feasible embodiment of the present application, as shown in FIG. 4 and FIG. 5 , the first light emitting surface 1112 d is a cylindrical surface.

[0055] Specifically, the first light-emitting surface 1112d is configured as a cylindrical surface to collimate the light passing through the first light-emitting surface 1112d in a single direction, converging the light and ensuring light energy while reducing the size of the light-emitting lens 112. Furthermore, the first light-emitting surface 1112d collimates the light in a single horizontal direction, and is a curved surface formed by stretching a horizontal cross-section along a vertical cross-section.

[0056] In a feasible embodiment of the present application, the light emitting lens 112 has a second light emitting surface 112 a , and the second light emitting surface 112 a is a cylindrical surface.

[0057] Specifically, the second light-emitting surface 112a is configured as a cylindrical surface to unidirectionally collimate the light passing through the second light-emitting surface 112a, converging the light to ensure the light energy of the light pattern. Furthermore, the second light-emitting surface 112a collimates the light in a vertical unidirectional manner, and is a curved surface formed by stretching its vertical cross-section along its horizontal cross-section.

[0058] When the second light-emitting surface 112a of the light-emitting lens 112 is a cylindrical surface, and the first light-emitting surface 1112d of the primary optical element 1112 is also a cylindrical surface, and both collimate light in a single direction, the cross-section of the second light-emitting surface 112a and the longitudinal section of the first light-emitting surface 1112d are perpendicular to each other. Light emitted by the light source 1111 is converged by the first light-emitting surface 1112d of the primary optical element 1112 and collimated in one direction. When the light enters the light-emitting lens 112 and exits from the second light-emitting surface 112a of the light-emitting lens 112, it is converged again, and the second light-emitting surface 112a collimates the light in another direction. At this point, the light pattern projected by the light-emitting lens 112 has a higher light energy due to its more concentrated light.

[0059] 1 to 7 , this embodiment provides an optical system 110 , including at least one optical module 111 in the aforementioned embodiments.

[0060] In a feasible embodiment of the present application, the primary optical element 1112 includes multiple primary optical elements 1112, which are arranged in a horizontal direction and integrally formed. The light-emitting lens 112 includes multiple primary optical elements 1112, which are arranged in a horizontal direction and integrally formed. The first light-emitting surface 1112d of each primary optical element 1112 collimates light in a single direction, and the longitudinal section of the first light-emitting surface 1112 is perpendicular to the transverse section of the second light-emitting surface 112a of the light-emitting lens 112. The light is first converged in the horizontal direction by the first light-emitting surface 1112d of the primary optical element 1112, and then converged in the vertical direction by the second light-emitting surface 112a of the light-emitting lens 112. The multiple primary optical elements 1112 are arranged in a horizontal direction so that the final light is projected onto the target plane to obtain the desired superimposed light pattern.

[0061] In a feasible embodiment of the present application, as shown in FIG. 4 to FIG. 7 , the optical system 110 further includes a circuit board 113 , and the first light source 1111 and the second light source 1113 of the optical module 111 are disposed on the circuit board 113 .

[0062] Specifically, the circuit board 113 is electrically connected to the first light source 1111 and the second light source 1113, so that the operating device connected to the circuit board 113 can control the first light source 1111 and the second light source 1113 to turn on and off respectively, making the control of the optical system 110 more convenient. The first light source 1111 and the second light source 1113 can be turned on together or separately to meet different lighting needs. Furthermore, as shown in Figure 7, the first light source 1111 and the second light source 1113 can be arranged on the same side of the same circuit board 113, reducing the use of circuit boards and reducing costs.

[0063] 4 and 6 , this embodiment provides a vehicle lamp 100 , which includes the optical system 110 in the aforementioned embodiment and a heat sink 120 connected to the optical system 110 .

[0064] Specifically, the radiator 120 includes a heat sink and a plurality of heat sinks arranged on the heat sink. The plurality of heat sinks are used to increase the overall heat dissipation area of ​​the radiator 120, so that the radiator 120 can quickly absorb the heat emitted by the first light source 1111 and the second light source 1113. The heat emitted by the first light source 1111 and the second light source 1113 is first transferred to the heat sink and then to the heat sink to avoid the first light source 1111 and the second light source 1113 from generating heat and affecting their working efficiency, thereby ensuring that the first light source 1111 and the second light source 1113 can work stably for a long time.

Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations.
