Description

Technical Field

[0001] The present invention relates to automotive headlights, and more particularly, to a headlight module that combines high and low beams. In addition, the present invention also relates to an automobile. Background Art

[0002] In the automotive lighting industry, as a new type of light source, LEDs have been widely used in the field of headlight manufacturing due to their advantages such as high luminous efficiency, small luminous area, low energy consumption, low manufacturing cost, and long service life. Due to the rapid development of LEDs, LED lighting headlights have changed from a configuration that was only available in high-end models of mid- to high-end automobiles in the past to a standard configuration for ordinary household cars today, and their market share has continued to increase at a speed that even exceeds all previous headlight technology innovations.

[0003] With the continuous increase in the market share of LED lighting, market competition has become increasingly fierce. Customers have put forward higher requirements for the performance of lighting systems and have begun to develop towards novel and unique shapes. Conventional modules are increasingly unable to meet the needs of the market. Technical characteristics such as small openings, small sizes, low energy consumption, low costs, and light weights will become a major development direction for future headlights. Therefore, it is urgent to design a lighting system with a unique shape and a compact size.

[0004] For the above reasons, the prior art is difficult to effectively meet the diverse development needs of the high-low beam integrated headlight module. Summary of the Invention

[0005] The first problem to be solved by the present invention is to provide a high-low beam integrated headlight module that is small in volume and can meet the low beam III-zone light pattern and high beam lighting requirements with high optical efficiency.

[0006] In addition, another problem to be solved by the present invention is to provide an automobile in which the high-low beam integrated headlight module can meet the requirements of diverse and miniaturized headlights, and can meet the low beam III-zone light pattern and high beam lighting requirements with high optical efficiency.

[0007] To solve the above technical problems, on the one hand, the present invention provides a high-low beam integrated headlight module. A high-low beam light propagation path is formed in the headlight module. A first light source assembly and a light guide lens are sequentially arranged on the high-low beam light propagation path from back to front. The first light source assembly is adapted to project light onto the light guide lens to form a low beam light pattern or a high beam light pattern. A second light source assembly is arranged on the side of the light guide lens. The second light source assembly is adapted to project light onto the light guide lens to adjust the brightness of the low beam III-zone light pattern, and when the headlight module realizes the low beam function, the light projection of the second light source assembly can light up the high beam function area shape of the light guide lens.

[0008] As a preferred structural form of the present invention, the light guide lens includes a plurality of lens units. Each of the single lens units forms a lens unit focus, and a first incident portion is formed on each of the single lens units; a second incident portion corresponding to the second light source assembly is formed on the side portion of the light guide lens.

[0009] More preferably, the first light source assembly includes a lighting light source and a reflection element. The light guide lens is adapted to converge the light after the lighting light source passes through the reflection element to form a low beam light pattern or a high beam light pattern.

[0010] A plurality of small reflectors are provided on or integrally formed on the reflection element. Each of the small reflectors is adapted to converge the reflected light to the lens unit focus corresponding to each of them, and project light through each of the lens units.

[0011] Furthermore, the lighting light source is an LED light source.

[0012] As another preferred structural form of the present invention, each of the lens units is a convex lens.

[0013] As yet another preferred structural form of the present invention, the first light source assembly further includes a lighting light source heat dissipation unit provided on the lighting light source.

[0014] As a specific structural form of the present invention, a light guide lens light exit portion is formed at the front end of the light guide lens. The light guide lens light exit portion is a plane, an inward concave curved surface or an outward convex curved surface.

[0015] As another specific structural form of the present invention, the second light source assembly includes an auxiliary light source and an auxiliary light source heat dissipation unit provided on the auxiliary light source. The auxiliary light source is adapted to project light into the light guide lens from the side portion of the light guide lens to light up the light guide lens, and the light projected by the auxiliary light source can adjust the brightness of the low beam III area light pattern after being reflected by the light guide lens, and when the vehicle headlight module realizes the low beam function, the styling of the high beam function area of the light guide lens can be lit up.

[0016] More specifically, the auxiliary light source is an LED light source.

[0017] In addition, the present invention further provides an automobile, which includes the low beam and high beam integrated vehicle headlight module according to any one of the above technical solutions.

[0018] Through the above technical solution, the present invention provides a headlight module with integrated high and low beams. A propagation path for high and low beam light rays is formed inside the headlight module. A first light source assembly and a light guide lens are successively arranged on the propagation path of the high and low beam light rays from the rear to the front. The first light source assembly is adapted to project light rays onto the light guide lens to form a low beam light pattern or a high beam light pattern. A second light source assembly is arranged on the side of the light guide lens. The second light source assembly is adapted to project light rays onto the light guide lens to be able to adjust the brightness of the light pattern in the III area of the low beam. When the headlight module realizes the low beam function, the light projection of the second light source assembly can light up the shape of the high beam function area of the light guide lens. The headlight module with integrated high and low beams of the present invention has a small volume, and can meet the requirement that the light pattern in the III area of the low beam complies with regulations. At the same time, when the headlight module realizes the low beam function, the high beam function area of the light guide lens can be lit up together in shape, which can meet the unique shape and diverse requirements of the headlight market for headlights with integrated high and low beams.

[0030] The following further details the specific embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for explaining and illustrating the present invention, and are not used to limit the present invention.

[0031] First of all, it should be noted that some orientation terms involved in the following description to clearly illustrate the technical solution of the present invention, such as "rear end", "front end", etc., are the meanings analogized according to the orientation indicated by the light-emitting path. For example, taking a light guide lens as an example, the end of the lens close to the illumination light source is the rear end, and the end far from the illumination light source is the front end; it can also be understood that the end where the light emitted by the illumination light source enters is the rear end, and the end where the far light rays are emitted is the front end.

[0032] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Therefore, the features defined with "first" and "second" may explicitly or implicitly include one or more of the said features.

[0033] In addition, for the convenience of description below, according to the description of the overall orientation of the vehicle by engineers in the automotive industry, the left-right direction represents the left-right direction of the vehicle in normal use, the front-rear direction represents the front-rear direction of the vehicle in normal use, and the up-down direction represents the up-down direction of the vehicle in normal use.

[0034] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "mounted" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0035] As Figure 1 shown, the present invention provides a headlight module with integrated high and low beams. A high and low beam light propagation path is formed inside the headlight module. A first light source component and a light guide lens 1 are sequentially arranged on the high and low beam light propagation path from the rear to the front. The first light source component is adapted to project light onto the light guide lens 1 to form a low beam light pattern or a high beam light pattern. A second light source component is arranged on the side of the light guide lens 1. The second light source component is adapted to project light onto the light guide lens 1 to be able to adjust the brightness of the low beam III area light pattern, and when the headlight module realizes the low beam function, the light projection of the second light source component can light up the high beam function area shape of the light guide lens 1.

[0036] From Figure 1It can be seen that the light emitted by the second light source component can adjust the brightness of the low beam III area light pattern after passing through the light guide lens 1, and can ensure that the low beam III area light pattern is not overly bright and complies with regulatory requirements. At the same time, it can also light up the light guide lens 1 when the first light source component forms low beam illumination, achieving the lighting effect of the high beam functional area of the light guide lens 1 in the low beam illumination state. While meeting the lighting requirements, it can meet more requirements for lighting up the shape. The light emitted by the first light source component is converged by the light guide lens 1 and then emitted, which can achieve high beam or low beam illumination, and at the same time when the low beam is lit, it can achieve the lighting effect of the high beam part being lit, and can achieve a unique low beam lighting effect, improving the market competitiveness of the product.

[0037] Here, it needs to be explained that the high beam functional area is the part on the light guide lens 1 for projecting high beam light. And the lighting up of the shape is not the high beam functional area of the light guide lens 1 realizing the high beam illumination function, but is lit by the second light source component (i.e., the LED light source is lit), making the lighting shape of the entire vehicle lamp module more beautiful.

[0038] As a preferred embodiment of the present invention, the light guide lens 1 includes a plurality of lens units 11. Each individual lens unit 11 forms a lens unit focus 7 respectively, and a first incident portion 12 is formed on each individual lens unit 11; a second incident portion 13 corresponding to the second light source component is formed on the side of the light guide lens 1.

[0039] As Figure 2 shown, the light guide lens 1 includes a plurality of lens units 11. Each of the lens units 11 has its own lens unit focus 7. The rear end of a single lens unit focus 7 is the first incident portion 12, and on the side of the light guide lens 1, a second incident portion 13 for the light in the second light source component to enter is formed. The light emitted from the first light source component can form a high beam illumination light pattern or a low beam illumination light pattern after passing through the light guide lens 1. The light emitted from the second light source component arranged on the side enters the light guide lens 1 through the second incident portion 13, and can adjust the brightness of the low beam III area light pattern through the light guide lens 1, and ensure that the brightness of the low beam III area light pattern complies with regulatory requirements, and can light up the high beam functional area of the light guide lens 1 when the first light source component realizes low beam illumination, achieving the lighting effect that the high beam functional area can also be lit simultaneously.

[0040] As another preferred embodiment of the present invention, the first light source component includes a lighting light source 4 and a reflection element 5. The light guide lens 1 is adapted to converge the light from the lighting light source 4 after passing through the reflection element 5 to form a low beam light pattern or a high beam light pattern; a plurality of small reflectors are provided or integrally formed on the reflection element 5. Each of the small reflectors is adapted to converge the reflected light to the respective corresponding lens unit focus 7, and project light through each of the lens units 11.

[0041] Here, the illumination light source 4 can serve as both a low beam light source and a high beam light source. If the illumination light source 4 serves as a low beam light source, the light rays emitted by the low beam light source are converged by the reflecting element 5 and then projected onto the light guide lens 1, and then emitted from the light guide lens 1 to form a low beam light pattern; if the illumination light source 4 serves as a high beam light source, the light rays emitted by the high beam light source are converged by the reflecting element 5 and then projected onto the light guide lens 1, and then emitted from the light guide lens 1 to form a high beam light pattern.

[0042] Moreover, a plurality of small reflectors are provided or integrally formed on the reflecting surface of the reflecting element 5. The plurality of small reflectors together form the reflecting area of the reflecting element 5. Each small reflector can converge the reflected light to the lens unit focus 7 of each corresponding lens unit 11, and can project light rays through the corresponding lens unit 11. Figure 1 Although only one lens unit focus 7 is marked in the figure, in fact, each lens unit 11 has its own focus, and each lens unit 11 can correspond to a small reflector. This is not shown in detail in the figure, but this does not affect those skilled in the art's understanding of this technology. Figure 1 This is not shown in detail in the figure, but this does not affect those skilled in the art's understanding of this technology.

[0043] More preferably, the illumination light source 4 is an LED light source.

[0044] Further preferably, each of the lens units 11 is a convex lens.

[0045] From Figure 2 As can be seen from the figure, the light guide lens 1 is composed of a plurality of lens units 11. A single lens unit 11 is a convex lens protruding towards the rear end, that is, the first incident portion 12 formed on the single lens unit 11 protrudes towards the direction of the second light source assembly, facilitating the small reflector to project the reflected light rays onto the corresponding lens unit 11, so as to form a high beam light pattern or a low beam light pattern that meets the lighting requirements.

[0046] As another preferred embodiment of the present invention, the first light source assembly further includes an illumination light source heat dissipation unit 6 provided on the illumination light source 4.

[0047] As a specific embodiment of the present invention, a light guide lens light emitting portion 14 is formed at the front end of the light guide lens 1. The light guide lens light emitting portion 14 is a plane, an inner concave curved surface or an outer convex curved surface.

[0048] Whether it is a low beam light pattern or a high beam light pattern, the light rays are all emitted from the illumination light source 4, pass through the first incident portion 12 and then are emitted from the light guide lens light emitting portion 14. However, the light guide lens light emitting portion 14 is not limited to Figure 2The planar structure shown may also be a curved surface structure, which may be a concave curved surface or a convex curved surface. The longitudinal section lines of the longitudinal sections of these curved surfaces may be arc line structures, parabola structures, or free curved surface structures, mainly depending on the actual light illumination requirements and the lens lighting effect requirements.

[0049] It should be explained that the longitudinal section refers to the plane presented by the light guide lens in the vertical direction after the light guide lens is virtually divided by a virtual plane that is parallel to the front-rear direction of the light guide lens and perpendicular to the horizontal direction. The longitudinal section line is the curve at the rear edge of the longitudinal section, that is, the curve obtained after the longitudinal section intersects with the first incident part 14.

[0050] As another specific embodiment of the present invention, the second light source assembly includes an auxiliary light source 2 and an auxiliary light source heat dissipation unit 3 provided on the auxiliary light source 2. The auxiliary light source 2 is adapted to project light into the light guide lens 1 from the side of the light guide lens 1 to light up the light guide lens 1, and the light projected by the auxiliary light source 2 can be reflected by the light guide lens 1 to adjust the brightness of the low beam III area light pattern, ensuring that the brightness of the low beam III area light pattern meets the regulatory requirements. At the same time, when the first light source assembly realizes low beam lighting, the high beam function area on the light guide lens 1 is also lit up together, meeting more styling requirements.

[0051] From Figure 1 and Figure 3 It can be seen that the auxiliary light source 2 is arranged on the side of the light guide lens 1, and the light emitted from the auxiliary light source 2 enters the light guide lens 1 from the side of the light guide lens 1, that is, the light emitted from the auxiliary light source 2 enters through the second incident part 13. After being reflected by the light guide lens 1, it can adjust the brightness of the low beam III area light pattern, and ensure that the low beam III area meets the regulatory requirements. And when the low beam is lit, the high beam function area of the light guide lens 1 is also lit up together, which can achieve diverse lighting effects, meet the vehicle headlight lighting requirements, and has a better lighting effect, improving the market competitiveness of the product.

[0052] More specifically, the auxiliary light source 2 is an LED light source.

[0053] Similar to the lighting light source 4, the auxiliary light source 2 is also an LED light source. As a new type of light source, LED light sources are increasingly widely used in the field of vehicle headlights. LED light sources have high luminous efficiency, low power consumption, long service life, strong safety and reliability, and are environmentally friendly and pollution-free. Therefore, they are new light sources with development prospects.

[0054] Furthermore, the present invention also provides an automobile, which includes the high and low beam integrated vehicle headlight module described in any one of the above technical solutions.

[0055] As can be seen from the above description, the present invention provides a headlight module with integrated high and low beams. A high and low beam light propagation path is formed inside the headlight module with integrated high and low beams. A first light source assembly and a light guide lens 1 are successively arranged on the high and low beam light propagation path from back to front. The first light source assembly is adapted to project light onto the light guide lens 1 to form a low beam light pattern or a high beam light pattern. A second light source assembly is arranged on the side of the light guide lens 1. The second light source assembly is adapted to project light onto the light guide lens 1 to be able to adjust the brightness of the light pattern in the third area of the low beam. When the headlight module realizes the low beam function, the light projection of the second light source assembly can light up the shape of the high beam function area of the light guide lens 1. The headlight module with integrated high and low beams of the present invention is small in volume, and can meet the requirement that the brightness of the light pattern in the third area of the low beam complies with the regulations and the requirement of special lighting effects, and can meet the unique shape and diversified requirements of the headlight market for the headlight with integrated high and low beams.

[0056] The preferred embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solutions of the present invention, and these simple modifications all belong to the protection scope of the present invention.

[0057] In addition, it should be noted that, among the various specific technical features described in the above specific embodiments, they can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, the present invention will not separately describe various possible combination methods.

[0058] In addition, any combination can be made between various different embodiments of the present invention, as long as it does not violate the idea of the present invention, it should also be regarded as the content disclosed by the present invention.
