TECHNICAL FIELD

[0001] The present application relates to the field of vehicle lamp lighting, in particular to a high beam optical module and a vehicle lamp. BACKGROUND

[0002] With the development of automobile lighting technology, LED headlamps have rapidly popularized in a short time, and the market share is increasing, and the market competition is becoming more and more fierce. The performance requirements of customers for the lighting system have gradually been shaped, and have begun to develop towards novelty and uniqueness. In recent years, with the development of automobile lighting modules, the vehicle lamp modeling has gradually developed from the monotonous round or square large lens in the past years to the strip or line modeling trend, and the novel and unique vehicle lamp can highlight the automobile modeling.

[0003] However, the optical system of the existing strip or line vehicle lamp is complex, and the light efficiency is not high, which affects the brightness of the vehicle lamp. SUMMARY

[0008] The light emitted by the light source passes through the first lens and the second lens in sequence, wherein the first lens is a convex lens and has the function of converging light; therefore, when parallel light is incident on the first lens, it shows a converging trend, and the first lens as a convex lens provides a premise for the beam narrowing of the light; and the final beam narrowing of the light is determined by the position of the second lens on the beam narrowing path of the first lens. And the light beam narrowed by the first lens is emitted as parallel light after passing through the second lens.

[0009] Further, the light exit surface of the first lens is convex, the second lens is a convex lens, the light entrance surface or the light exit surface of the second lens is convex, the focal length of the first lens is greater than the focal length of the second lens, and the focal point of the first lens and the focal point of the second lens coincide.

[0010] The first lens and the second lens are both convex lenses, the light exit surface of the first lens is convex, the light entrance surface of the second lens is convex, the focal length of the first lens is greater than the focal length of the second lens, and the focal point of the first lens and the focal point of the second lens coincide.

[0011] Alternatively, the light exit surface of the second lens is convex, and the light entrance surface of the second lens is a plane, which can also achieve beam narrowing and obtain a narrower light exit port.

[0012] Further, the light exit surface of the first lens is convex, the second lens is a concave lens, the light entrance surface or the light exit surface of the second lens is concave, and the second lens is located between the focal point of the first lens and the first lens.

[0013] The second lens is a concave lens, the light entrance surface of the second lens is concave, and the light exit surface of the second lens is a plane.

[0015] Further, a collimating lens is arranged between the light source and the first lens, and the light rays emitted by the light source are incident on the first lens after passing through the collimating lens.

[0021] The integral mirror is a special-shaped structure, the reflecting surface is connected with the light exit surface of the integral mirror, and the reflecting surface and the light entrance surface are not connected, forming a gap. In the first direction, the size of the light entrance surface is smaller than the size of the light exit surface, so that the projection of the integral mirror in the direction perpendicular to the paper plane forms a shape similar to a trapezoid with one end large and one end small, and the projection of the reflecting surface in the direction perpendicular to the paper plane can be approximately regarded as a leg of the trapezoid. In addition, the reflecting surface is an arc surface, so that when the projection of the reflecting surface in the direction perpendicular to the paper plane is regarded as a leg of the trapezoid, the leg is an arc.

[0022] Further, the reflecting surface is a full reflecting surface. When the light reaches the full reflecting surface, total reflection is achieved.

[0023] Further, the integral mirror is a rotary body structure, and the reflecting surface is a peripheral wall of the rotary body structure. The light is incident on the light entrance surface, is reflected by the reflecting surface, and is emitted by the light exit surface and directed to the second lens.

[0024] Further, a notch is formed on the light entrance surface of the integral mirror, an axis of the notch is collinear with an axis of the integral mirror, and the bottom surface of the notch and the side peripheral surface of the notch are both the light entrance surface of the integral mirror.

A notch is formed on the light entrance surface, the bottom surface of the notch and the side peripheral surface of the notch can both be the light entrance surface of the integral mirror. The light source is located on the axis (main optical axis) of the integral mirror, and among the light emitted by the light source, part of the light is directly emitted along the axis via the bottom surface of the notch, part of the light is emitted toward the side peripheral surface of the notch, is reflected by the side peripheral surface toward the peripheral wall of the integral mirror, and then sequentially passes through the light exit surface of the integral mirror and the second lens.

[0026] Further, the bottom surface of the notch is convex and convex toward the direction of the light source. When the light source is incident on the bottom surface of the notch, the light is incident via the convex surface.

[0027] Further, the first lens is provided with a reflecting element having a reflecting surface extending towards the first lens, and the light emitting surface of the light source faces the reflecting surface so that the light emitted by the light source is reflected by the reflecting surface of the reflecting element and then enters the first lens.

[0054] It should be noted that: similar reference numbers and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0055] It should be noted that: similar reference numbers and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0056] Please refer to Figure 1As shown, the high beam optical module provided by the embodiment of the application comprises a light source 200, and a first lens 101 and a second lens 102 arranged in sequence in the transmission direction of the light path. The first lens 101 is a convex lens, and the focal point of the first lens 101 coincides with the focal point of the second lens 102, or the second lens 102 is located between the focal point of the first lens 101 and the first lens 101. The light emitted by the light source 200 is sequentially emitted after passing through the first lens 101 and the second lens 102, thereby realizing beam narrowing of the light in a first direction perpendicular to the light emitting direction.

[0057] The light source 200 emits light, and the light sequentially passes through the first lens 101 and the second lens 102. The first lens 101 is a convex lens and has the function of converging light. Therefore, when parallel light is incident on the first lens 101, the light has a converging tendency. The first lens 101 as a convex lens provides a premise for beam narrowing of the light. The final realization of beam narrowing of the light depends on the position of the second lens 102 on the light path of the first lens 101. Moreover, the light narrowed by the first lens 101 is emitted as parallel light after passing through the second lens 102.

[0058] In the application, when the second lens 102 is a convex lens, if the focal point of the first lens 101 coincides with the focal point of the second lens 102, the light can be narrowed by the first lens 101, and then emitted as parallel light by the second lens 102. Moreover, the emitted parallel light is narrowed relative to the parallel light incident on the first lens 101.

[0059] Alternatively, when the second lens 102 is a concave lens, the second lens 102 is located between the focal point of the first lens 101 and the first lens 101. The light can be narrowed by the first lens 101, and then emitted as parallel light by the second lens 102. Moreover, the emitted parallel light is narrowed relative to the parallel light incident on the first lens 101.

[0060] Because the size of the second lens 102 is much smaller than the size of the first lens 101, the second lens 102 serves as the light emitting lens of the high beam optical module, so that the light emitting port of the high beam optical module is a narrow opening. Moreover, the light is narrowed in the first direction, thereby improving the brightness and light efficiency of the emitted light, forming a bright narrow light spot, and being applied to a car lamp. If the second lens 102 is narrow and long, a strip-shaped or line-shaped car lamp can be formed. It should be noted that the first direction is a certain direction perpendicular to the light emitting direction, the light is narrowed in the first direction, and the light emitting port of the high beam optical module is narrow in the first direction.

[0061] Thus, the high beam optical module provided by the embodiment of the application comprises a first lens 101 and a second lens 102. The first lens 101 is a convex lens, and the light emitted by the light source 200 is converged after passing through the first lens 101, so that the light is shrunk. The focal point of the second lens 102 coincides with the focal point of the first lens 101, or the second lens 102 is located between the focal point of the first lens 101 and the first lens 101, so that the converged light is emitted as parallel light after passing through the second lens 102. Compared with the parallel light incident on the first lens 101, the parallel light emitted in the first direction perpendicular to the light emitting direction is shrunk, the high beam optical module can form a narrow light emitting port in the first direction, and a narrow light spot is obtained. The light is emitted after being shrunk, and the emitted light has the characteristics of high light efficiency and high brightness. The parallel light is obtained through the cooperation of the first lens 101 and the second lens 102, which is convenient for vehicle lamp lighting. The second lens 102 is small in size, so that the overall structure of the high beam optical module is compact and low in cost.

[0062] Specifically, the first lens 101 and the second lens 102 can have different surface combinations to realize the shrinking of the light. As shown in FIG. 1, Figure 1 in an implementation manner of the application, the first lens light emitting surface 101c is a convex surface, the second lens 102 is a convex lens, the light incident surface of the second lens 102 is a convex surface, the light emitting surface of the second lens 102 is a plane, the focal length of the first lens 101 is greater than the focal length of the second lens 102, and the focal point of the first lens 101 coincides with the focal point of the second lens 102.

[0063] The first lens 101 and the second lens 102 are both convex lenses, the first lens light emitting surface 101c is a convex surface, the light incident surface of the second lens 102 is a convex surface, the focal length of the first lens 101 is greater than the focal length of the second lens 102, and the focal point of the first lens 101 coincides with the focal point of the second lens 102. The light is converged and shrunk after passing through the first lens 101, and then emitted as parallel light after passing through the second lens 102. Compared with the parallel light incident on the first lens 101, the light emitted after passing through the second lens 102 is shrunk, and a narrow light emitting port is obtained.

[0064] In another implementation manner of the application, as shown in FIG. 3, Figure 2 the first lens light emitting surface 101c is a convex surface, the second lens 102 is a convex lens, the light incident surface of the second lens 102 is a plane, the light emitting surface of the second lens 102 is a convex surface, the focal length of the first lens 101 is greater than the focal length of the second lens 102, and the focal point of the first lens 101 coincides with the focal point of the second lens 102.

[0065] Different from the first implementation, the light exit surface of the second lens 102 is a convex surface in the second implementation, and the rest of the settings are consistent with the first implementation. Compared with the second implementation in which the light exit surface of the second lens 102 is a convex surface, in the first implementation, the light exit surface of the second lens 102 is set to be a plane, the far light shape is clearer, and the aberration is smaller.

[0066] In the third implementation of the present application, as shown in Figure 3 the light exit surface of the first lens 101c is a convex surface, the second lens 102 is a concave lens, the light entrance surface of the second lens 102 is a concave surface, the light exit surface of the second lens 102 is a plane, and the second lens 102 is located between the focal point of the first lens 101 and the first lens 101.

[0067] At this time, the second lens 102 is a concave lens, the light entrance surface of the second lens 102 is a concave surface, and the light exit surface of the second lens 102 is a plane. When the second lens 102 is located between the focal point of the first lens 101 and the first lens 101, in other words, the second lens 102 is located on the light path of the light rays converging through the first lens 101, so as to realize the beam shrinking of the light rays in the first direction, and obtain a narrower light exit port.

[0068] In the fourth implementation of the present application, as shown in Figure 4 the light exit surface of the first lens 101c is a convex surface, the second lens 102 is a concave lens, the light entrance surface of the second lens 102 is a plane, the light exit surface of the second lens 102 is a concave surface, and the second lens 102 is located between the focal point of the first lens 101 and the first lens 101.

[0069] In this case, the light exit surface of the second lens 102 is a concave surface, which can also realize the beam shrinking of the light rays in the first direction and obtain a narrower light exit port. Compared with the third implementation in which the light exit surface of the second lens 102 is a plane, in the fourth implementation, the light exit surface of the second lens 102 is set to be a concave surface, the far light shape is clearer, and the aberration is smaller.

[0070] On this basis, when the above four implementations are applied to a specific optical system, they can also be realized by other optical devices. The first implementation is taken as an example for description below, and the other three implementations can be referred to for implementation.

[0071] For example, in the first embodiment, a collimating lens is arranged between the light source 200 and the first lens 101. The light emitted by the light source 200 is incident on the first lens 101 and the second lens 102 in sequence after collimating by the collimating lens. After collimating by the collimating lens, the light is incident on the first lens 101 again.

[0072] The collimating lens and the first lens 101 can be separately arranged or integrally arranged; for example,Figures 5-7 As shown, the collimating lens and the first lens 101 are integrally arranged to form an integrated mirror 101A, the first lens light exit surface 101c is a convex surface, the integrated mirror 101A further has an integrated mirror reflection surface 101b between the integrated mirror light entrance surface 101a and the first lens light exit surface 101c, the light ray is incident from the integrated mirror light entrance surface 101a, reflected by the integrated mirror reflection surface 101b, and then exits from the first lens light exit surface 101c and is incident into the second lens 102.

[0073] The light exit surface of the integrated mirror 101A is the first lens light exit surface 101c, which is a convex surface; the integrated mirror 101A further has an integrated mirror reflection surface 101b, the light ray emitted by the light source 200 is incident from the integrated mirror light entrance surface 101a and is directed to the integrated mirror reflection surface 101b, and then is reflected by the integrated mirror reflection surface 101b and exits from the first lens light exit surface 101c, and finally enters the second lens 102 to complete the light beam shrinking.

[0074] The integrated mirror 101A in the present application is a special-shaped structure, wherein the integrated mirror reflection surface 101b is connected with the first lens light exit surface 101c, and there is a gap between the integrated mirror reflection surface 101b and the integrated mirror light entrance surface 101a; and the size of the integrated mirror light entrance surface 101a is smaller than the size of the first lens light exit surface 101c, so that the projection of the integrated mirror 101A in the direction perpendicular to the paper (as shown in Figure 6 The projection of the integrated mirror reflection surface 101b in the direction perpendicular to the paper can be approximately regarded as a waist of the trapezoid; in addition, the integrated mirror reflection surface 101b is an arc surface, so that when the projection of the integrated mirror reflection surface 101b in the direction perpendicular to the paper is regarded as a waist of the trapezoid, the waist is an arc line.

[0075] Further, the integrated mirror reflection surface 101b is a total reflection surface, and the light ray realizes total reflection after reaching the total reflection surface.

[0076] In a second embodiment, as shown in Figures 8-11 The integrated mirror 101A is a rotary body structure, and the integrated mirror reflection surface 101d is a peripheral wall of the rotary body structure. The end surfaces of the rotary body structure are the integrated mirror light entrance surface 101a and the first lens light exit surface 101c, respectively, the integrated mirror reflection surface 101d is the peripheral wall of the rotary body, the light ray is incident from the light entrance surface, reflected by the integrated mirror reflection surface 101d, and then exits from the first lens light exit surface 101c and is directed to the second lens 102.

[0077] In addition, a notch is formed on the integrated mirror light entrance surface 101a, the axis of the notch is collinear with the axis of the integrated mirror 101A, and the bottom surface 101e and the side peripheral surface 101f of the notch are both the integrated mirror light entrance surface 101a.

[0078] For example, the integrated mirror 101A forms a trapezoidal rotating structure, with the smaller end face being the light-incident surface and the larger end face being the convex light-exiting surface 101c of the first lens; a notch is formed on the light-incident surface, and the bottom surface 101e and the side peripheral surface 101f of the notch are both light-incident surfaces 101a of the integrated mirror; the light source 200 is located on the axis (principal optical axis) of the integrated mirror 101A, and in the light emitted from the light source 200, part of the light rays pass through the bottom surface 101e of the notch and are directly incident along the axis, and part of the light rays are incident on the side peripheral surface 101f of the notch, and are incident on the peripheral wall of the integrated mirror 101A for reflection, and then pass through the first light-exiting surface 101c and the second lens 102 in sequence.

[0079] The bottom surface 101e of the notch is convex and convex towards the light source 200, so that the light emitted from the light source 200 can enter the bottom surface 101e of the notch.

[0080] In the third embodiment of this application, as Figures 12-14 As shown, a reflector is provided on the light-incident side of the first lens 101. The reflector has a reflector reflective surface 103, which extends toward the first lens 101. The light-emitting surface of the light source 200 faces the reflector reflective surface 103 so that the light emitted from the light source 200 is reflected by the reflector reflective surface 103 and then enters the light-incident surface of the first lens 101.

[0081] The light emitted from the light source 200 first reaches the reflecting surface 103 of the reflector, and after being reflected by the reflecting surface 103, it is directed toward the light-incident surface of the first lens 101. Therefore, the reflecting surface 103 of the reflector must extend toward the first lens 101 so that the light-incident surface of the first lens 101 can receive the light reflected by the reflecting surface 103 of the reflector.

[0082] Optionally, the reflecting surface 103 of the reflector can be a parabolic, parabolic-like, ellipsoidal, or ellipsoidal surface. In this case, the reflector can be considered a parabolic, parabolic-like, ellipsoidal, or ellipsoidal mirror. The light source 200 is located at the focal point of the reflector. After being reflected by the reflecting surface 103, the light is converted into parallel light and directed towards the first lens 101. Setting the reflecting surface 103 of the reflector as a parabolic, parabolic-like, ellipsoidal, or ellipsoidal surface, when applied to searchlights or automotive headlights, can obtain parallel light, facilitating illumination. It should be noted that a parabolic-like mirror refers to a mirror with similar optical functions to a parabolic mirror, and an ellipsoidal mirror refers to a mirror with similar optical functions to an ellipsoidal mirror; both can convert light rays emitted from their focal point into parallel or nearly parallel light after reflection by their reflecting surface.

[0083] On the other hand, this application also provides a vehicle light, including the aforementioned high beam optical module.

[0084] The light source 200 emits light rays, which are emitted by the light-emitting end of the vehicle lamp after passing through the high beam optical module, for illumination. The emitted light rays pass through the beam reduction of the high beam optical module to form a narrow opening light-emitting effect in the first direction, meeting the modeling requirements, and the light rays have high brightness and high light efficiency, resulting in good illumination effect. The second lens has a small size, which can meet the modeling requirements while effectively reducing the cost and expanding the application range.

[0085] The above only describes some embodiments of the present application and is not intended to limit the present application. Those skilled in the art can make various changes and modifications to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.

[0086] Industrial applicability

[0087] The high beam optical module realizes beam reduction of the emitted light rays relative to the incident light rays in the first direction through the matching of the first lens 101 and the second lens 102, realizes a narrow opening light-emitting effect, for example, forms a strip-shaped or line-shaped vehicle lamp model, and the light-emitting port of the high beam optical module forms a narrow light-emitting port.
