Description

Cross-reference to related registration

[0001] This application claims the priority and benefits of Korean patent application No. 10-2025-0054610, which was filed with the Korean Intellectual Property Office on April 25, 2025, and the entire contents of which are hereby incorporated by reference pursuant to 35 USC § 119(a). Technical field

[0002] The present disclosure relates to a lamp for a vehicle. More precisely, the present disclosure relates to a lamp for a vehicle in which a first incident lens part and a second incident lens part are integrated to form several light distribution patterns. State of the art

[0003] Generally, a vehicle has various types of lights that serve both a lighting and a signaling function. The lighting function allows the driver to easily see objects around the vehicle during night driving. The signaling function informs drivers of other vehicles and pedestrians on the road about the vehicle's status.

[0004] Lamps include, for example, headlights (or front lights) and fog lights, which are primarily used for illumination, as well as turn signals, taillights, brake lights, and side marker lights, which are used for signaling. Regulations define the installation criteria and specifications for these lamps on a vehicle to ensure they can adequately perform their functions.

[0005] Among the lights on a vehicle, the headlight provides a low beam or high beam pattern to ensure good visibility to the driver during night driving. The headlight plays a crucial role in driving safety.

[0006] Recently, in addition to the performance of the headlights, the external design of the headlights and the light distribution patterns have also been considered important.

[0007] However, current technology requires the use of an aspherical lens with a single focal point to generate a specific light distribution pattern, which complicates various headlight designs and light distribution patterns. Consequently, there are limitations on the implementation of design features, and it is difficult to meet rapidly changing consumer demands.

[0008] Furthermore, in the prior art, different optical systems must be used to generate light distribution patterns for long distances and for short distances, which leads to the problem that the structure and manufacturing processes are complicated and the manufacturing costs increase.

[0009] Therefore, several studies have recently been conducted to achieve both structural simplification and improved design flexibility and light output through the integration of optical structures and the reduction of the number of components, but the study results are still insufficient. Thus, there is a need to develop a technology that can achieve both structural simplification and improved design flexibility and light output through the integration of optical structures and the reduction of the number of components. Summary

[0041] With reference to the Fig. 1 to 10, a lamp 10 for a vehicle according to an embodiment of the present disclosure can have a first light source part 100, a second light source part 200, a first incident lens part 300, a second incident lens part 400, a first reflection lens part 500 and / or a second reflection lens part 600.

[0042] The first light source part 100 can have one or more first light sources 110a, 110b, and 110c configured to emit light. The first light source part 100 can be arranged on one side with respect to a horizontal direction W. The multiple first light sources 110a, 110b, and 110c can be arranged in the horizontal direction W.

[0043] The second light source part 200 can have one or more second light sources 210a, 210b, 210c, 210d, 210e, and 210f configured to emit light. The second light source part 200 can be located on the opposite side of the first light source part 100. The second light source part 200 can be positioned at a predetermined distance or more from the first light source part 100. In particular, the second light source part 200 can be positioned in front of the first light source part 100. The multiple second light sources 210a, 210b, 210c, 210d, 210e, and 210f can be arranged in the horizontal direction W.

[0044] For the first light source part 100 and the second light source part 200, an element or device capable of emitting light can be used. For example, a diode (light-emitting diode, hereinafter referred to as "LED") can be used for the first light source part 100 and the second light source part 200. Furthermore, the first light source part 100 and the second light source part 200 can be mounted on a substrate part (not shown), such as a printed circuit board.

[0045] The first incident lens element 300 can be positioned and configured in front of the first light source element 100 to allow the light emitted by the first light source element 100 to propagate forward. The first incident lens element 300 can be positioned on one side with respect to the horizontal direction W.

[0046] The first incident lens part 300 may include all or some of the first light entry sections 310a, 310b and 310c and a first body section 320.

[0047] The first light entry sections 310a, 310b, and 310c can be arranged to face the first light sources 110a, 110b, and 110c, and configured such that the light rays emitted by the first light sources 110a, 110b, and 110c enter the first light entry sections 310a, 310b, and 310c and are totally reflected. That is, the first light entry sections 310a, 310b, and 310c can be provided as one or more first light entry sections 310a, 310b, and 310c, the number of which corresponds to the first light sources 110a, 110b, and 110c. The first light entry sections 310a, 310b and 310c can be formed in shapes that project backwards from the first body section 320.

[0048] The first body section 320 can be positioned upstream of one or more first light entry sections 310a, 310b, and 310c and integrated with these first light entry sections. The first body section 320 can be configured to direct forward the light rays entering the first body section 320 from the first light entry sections 310a, 310b, and 310c.

[0049] A light-emitting surface 321 can be formed on a front face of the first body section 320. That is, the light-emitting surface 321 of the first body section can be configured to allow the light directed from the first body section 320 to propagate forward. Additionally, the light-emitting surface 321 of the first body section 320 can be formed in a shape where a cross-sectional area in the horizontal direction W of the light-emitting surface 321 of the first body section 320 is concavely curved backward. More precisely, to improve the visibility of a central light distribution (hot zone), a central region of a cross-section in the horizontal direction W of the light-emitting surface 321 of the first body section 320 can be most strongly curved backward.In this case, the central light distribution refers to a high beam distribution pattern to ensure a field of vision of a central area of ​​the front.

[0050] With reference to the Fig.In sections 6 to 8, the light-emitting surface 321 of the first body section 320 further comprises a projection section 321a, which extends forward from one side of the light-emitting surface 321 of the first body section 320. For example, the projection 321a can be configured such that it is shifted towards the center of the first body section 320 with respect to the horizontal direction W towards the second incident lens part 400 and serves as a light-blocking device to reduce the luminance at a specific location. Since this light-sensitive area can vary depending on the light distribution requirements or design conditions of the application areas, the position, shape, and size of the projection section 321a can be modified differently according to the design conditions.

[0051] A lower surface 323 of the first body section can be designed such that it is inclined upwards in the direction of the light emission surface 321 of the first body section 320.

[0052] The rear surfaces 324 and 324a of the first body section 320 can have a central region 324a, from which one or more first light-entry sections 310a, 310b, and 310c project, and an outer edge region 324 configured to surround the first light-entry sections 310a, 310b, and 310c. The outer edge region 324 can project further rearward than the central region 324a and form a stepped section.

[0053] The width of the first body section 320 can decrease in the forward direction. Therefore, the width of the light-emitting surface 321 of the first body section 320 can be smaller than the width of each of the rear surfaces 324 and 324a of the first body section 320. That is, the shape narrowing in the forward direction can allow the light rays entering through the several first light-entry sections 310a, 310b, and 310c to be concentrated on the central area with respect to the horizontal direction W, so that the central light distribution can be formed on the light-emitting surface 321 of the first body section 320.

[0054] The first light entry sections 310a, 310b and 310c can each have all or some of a first central entry section 311, a first lateral entry section 312 and a first outer peripheral entry section 313.

[0055] The first central incidence section 311 can be configured to refract a first central light ray, which is part of the light emitted by the first light sources 110a, 110b and 110c, such that the first central light ray spreads to the central area of ​​the light exit surface 321 of the first body section.

[0056] The first lateral entry segment 312 can extend from the first central entry segment 311 to the first outer peripheral entry segment 313.

[0057] The first outer peripheral incidence section 313 can be configured to totally reflect a first peripheral light ray, which is another part of the light emitted by the first light sources 110a, 110b, and 110c, such that the first peripheral light ray propagates to the central region of the light-emitting surface 321 of the first body section 320. The first outer peripheral incidence section 313 can be configured to surround the first central incidence section 311.

[0058] A forward / backward distance L between a lower end 313b of the first outer peripheral incidence section and the first light source part 100 can be longer than a forward / backward distance L between an upper end 313a of the first outer peripheral incidence section and the first light source part 100. For example, the lower end 313b of the first outer peripheral incidence section can be farther from the first light source part 100 than the upper end 313a of the first outer peripheral incidence section is from the first light source part 100, so that a stepped section can be formed between the upper end 313a of the first outer peripheral incidence section and the lower end 313b of the first outer peripheral incidence section with respect to the forward / backward direction L.

[0059] The multiple first light entry sections 310a, 310b, and 310c can be configured such that the optical axes of the multiple first light entry sections 310a, 310b, and 310c approach a central axis in the forward direction with respect to the horizontal direction W of the light exit surface 321 of the first body section 320. For example, the multiple first light entry sections 310a, 310b, and 310c can be arranged symmetrically with respect to the central axis with respect to the horizontal direction W of the light exit surface 321 of the first body section 320, so that the light rays entering through the first light entry sections 310a, 310b, and 310c can propagate towards the central region of the light exit surface 321 of the first body section 320.

[0060] The second incident lens element 400 can be positioned and configured in front of the second light source element 200 to allow the light emitted by the second light source element 200 to propagate forward. The second incident lens element 400 can be positioned on the opposite side with respect to the horizontal direction W. Alternatively, the second incident lens element 400 can be positioned on one side of the first incident lens element 300 with respect to the horizontal direction W and integrated with the first incident lens element 300.

[0061] The second incident lens part 400 can have all or some of the second light entry sections 410a, 410b, 410c, 410d, 410e and 410f and a second body section 420.

[0062] The second light entry sections 410a, 410b, 410c, 410d, 410e and 410f can be arranged such that they face the second light sources 210a, 210b, 210c, 210d, 210e and 210f and are configured such that the light rays emitted by the second light sources 210a, 210b, 210c, 210d, 210e and 210f enter the second light entry sections 410a, 410b, 410c, 410d, 410e and 410f and are totally reflected. This means that the second light entry sections 410a, 410b, 410c, 410d, 410e and 410f can be provided as one or more second light entry sections 410a, 410b, 410c, 410d, 410e and 410f, the number of which corresponds to the second light sources 210a, 210b, 210c, 210d, 210e and 210f. The second light entry sections 410a, 410b, 410c, 410d, 410e and 410f can be configured in shapes that project rearward from the second body section 420.

[0063] The second body section 420 can be positioned in front of one or more second light entry sections 410a, 410b, 410c, 410d, 410e, and 410f and integrated with one or more second light entry sections 410a, 410b, 410c, 410d, 410e, and 410f. The second body section 420 can be configured to direct forward the light rays entering the second body section 420 from one or more second light entry sections 410a, 410b, 410c, 410d, 410e, and 410f.

[0064] A light-emitting surface 421 can be formed on a front face of the second body section 420. That is, the light-emitting surface 421 of the second body section 420 can be configured to allow the light directed from the second body section 420 to propagate forward. Furthermore, the light-emitting surface 421 of the second body section 420 can be formed in a shape where the cross-sectional shape in the horizontal direction W of the light-emitting surface 421 of the second body section 420 is convexly curved forward. More precisely, the cross-sectional shape in the horizontal direction W of the light-emitting surface 421 of the second body section 420 can be designed to be gently curved so that the light is scattered over a larger area.With the aforementioned configuration, the light rays emitted by the secondary light sources 210a, 210b, 210c, 210d, 210e, and 210f can spread out at various angles, thus forming a completely uniform peripheral light distribution (wide zone). In this case, the peripheral light distribution refers to a light distribution pattern that ensures a field of vision at the front edge and guarantees visibility when a vehicle is turning.

[0065] A lower surface 423 of the second body section can be designed such that it is inclined upwards in the direction of the light emission surface 421 of the second body section 420.

[0066] The rear surfaces 424 and 424a of the second body section 420 can have a central region 424a, from which one or more second light entry sections 410a, 410b, 410c, 410d, 410e, and 410f project, and an outer edge region 424 configured to surround the second light entry sections 410a, 410b, 410c, 410d, 410e, and 410f. The outer edge region 424 can project further rearward than the central region 424a and define a stepped section.

[0067] The width of the second body section 420 can increase in the forward direction. Therefore, the width of the light-emitting surface 421 of the second body section 420 can be greater than the width of each of the rear surfaces 424 and 424a of the second body section 420. That is, the shape widened in the forward direction can allow the light rays entering through the multiple second light-entry sections 410a, 410b, 410c, 410d, 410e, and 410f to exit from different positions on the light-emitting surface 421 of the second body section 420, thereby forming different light distribution angles and realizing peripheral light distribution over a large area.Furthermore, since the width of the light emission surface is large, the optical axes of the second light sources 210a, 210b, 210c, 210d, 210e and 210f can be maintained without distortion, and a more uniform light distribution can be achieved, thereby improving the overall light output.

[0068] The second light entry sections 410a, 410b, 410c, 410d, 410e and 410f can each have all or some of a second central entry section 411, a second lateral entry section 412 and a second outer peripheral entry section 413.

[0069] The second central incidence section 411 can be configured to refract a second central light ray, which is part of the light emitted by the second light sources 210a, 210b, 210c, 210d, 210e and 210f, so that the second central light ray propagates towards the central area of ​​the light exit surface 421 of the second body section 420.

[0070] The second lateral entry segment 412 can extend from the second central entry segment 411 to the second outer peripheral entry segment 413.

[0071] The second outer peripheral incidence section 413 can be configured to totally reflect a second peripheral light ray, which is another part of the light emitted by the second light sources 210a, 210b, 210c, 210d, 210e, and 210f, such that the second peripheral light ray propagates to the central region of the light-emitting surface 421 of the second body section 420. The second outer peripheral incidence section 413 can be configured to surround the second central incidence section 411.

[0072] A forward / backward distance L between a lower end 413b of the second outer peripheral incidence section and the second light source part 200 can be longer than a forward / backward distance L between an upper end 413a of the second outer peripheral incidence section and the second light source part 200. For example, the lower end 413b of the second outer peripheral incidence section can be farther from the second light source part 200 than the upper end 413a of the second outer peripheral incidence section is from the second light source part 200, such that a step section can be formed between the upper end 413a of the second outer peripheral incidence section and the lower end 413b of the second outer peripheral incidence section with respect to the forward / backward direction L.

[0073] The light rays entering through the multiple second light entry sections 410a, 410b, 410c, 410d, 410e, and 410f can propagate forward along the optical axes of the light entry sections and exit from different positions on the light exit surface 421 of the second body section 420. That is, since the light exit surface 421 of the second body section 420 is designed as a curved surface that is slightly curved in the horizontal direction W, the light rays entering the light entry sections can exit in different directions according to the position and curvature of the light exit surface 421 of the second body section 420. Therefore, the light can be scattered over the entire light exit surface 421 of the second body section 420, thus forming the peripheral light distribution.

[0074] The width of the first lens section 300 in the horizontal direction W can be smaller than the width of the second lens section 400 in the horizontal direction W.

[0075] A top surface 322 of the first body section and a top surface 422 of the second body section can be integrated.

[0076] The light-emitting surface 321 of the first body section 320 can be positioned in front of the light-emitting surface 421 of the second body section 420, and the rear surfaces 324 and 324a of the first body section 320 can be positioned behind the rear surfaces 424 and 424a of the second body section 420. Therefore, a step section can be formed between the first incident lens section 300 and the second incident lens section 400 with respect to the forward / backward direction L.

[0077] The first deflection lens section 500 can be positioned and configured in front of the first incidence lens section 300 to allow the light exiting the first incidence lens section 300 to enter the first deflection lens section 500. The light passing from the first light source section 100 through the first incidence lens section 300 and the first deflection lens section 500 can form the central light distribution.

[0078] The first lens element 500 can have one or both of a first incidence surface 510 and a first emission surface 520.

[0079] The first incidence surface 510 can be configured to allow light exiting the first incidence lens part 300 to enter the first incidence surface 510. The cross-sectional shape in the horizontal direction W of the first incidence surface 510 can be formed in a rearwardly convex shape.

[0080] The first emission surface 520 can be configured to allow the light entering the first incidence surface 510 to propagate forward. The cross-sectional shape in the horizontal direction W of the first emission surface 520 can be formed in a forward-convex curve. For example, the first incidence surface 510 and the first emission surface 520 can be symmetrical in the horizontal direction W with respect to the optical axis of the first emission lens part 500.

[0081] The second emission lens element 600 can be positioned and configured upstream of the second incidence lens element 400 to allow light exiting the second incidence lens element 400 to enter the second emission lens element 600. The second emission lens element 600 can be positioned on one side of the first emission lens element 500 with respect to the horizontal direction W and integrated with the first emission lens element 500.

[0082] The light passing from the second light source part 200 through the second incident lens part 400 and the second expelled lens part 600 can form the peripheral light distribution surrounding the central light distribution. The central and peripheral light distributions can overlap to form a low beam distribution pattern.

[0083] The second emission lens part 600 can have one or both of a second incidence surface 610 and a second emission surface 620.

[0084] The second incidence surface 610 can be configured to allow the light exiting the second incidence lens part 400 to enter the second incidence surface 610.

[0085] The second incident surface 610 can be designed such that, with respect to the horizontal direction W of the second emission lens part 600, it is curved backwards in a direction from one side end to the other side end.

[0086] The second emission surface 620 can be configured to allow light entering the second incidence surface 610 to exit. The second emission surface 620 can be designed to have a shape that corresponds to the second incidence surface 610 with respect to the horizontal direction W of the second emission lens part 600.

[0087] More precisely, the first emission surface 520 and the second emission surface 620 can be configured in different shapes, but they can be continuous without a stepped section in the horizontal direction W. The first emission surface 520 and the second emission surface 620, which are located at the front and define the external appearance of the lamp 10 for a vehicle, are continuous, so that the lamp 10 for a vehicle, according to the present disclosure, can achieve an advantageous design effect by minimizing interruptions between the light distribution patterns with different properties.

[0088] The width of the first emission lens portion 500 in the horizontal direction W can be smaller than the width of the second emission lens portion 600 in the horizontal direction W. In particular, the first emission lens portion 500 can be configured to have a comparatively small width in the horizontal direction W, so that the concentrated light is directed and emitted in a predetermined direction. In contrast, since the second emission lens portion 600 is structured to scatter the light rays transmitted by the multiple second light entry sections 410a, 410b, 410c, 410d, 410e, and 410f over a large area and emit the light rays, the second emission lens portion 600 can be configured to have a larger width in the horizontal direction W.

[0089] The first incidence surface 510 can be positioned in front of the second incidence surface 610, and the first discharge surface 520 can be positioned in front of the second discharge surface 620.

[0090] The width of the first incident lens portion 300 in the horizontal direction W can be greater than the width of the first exhaled lens portion 500 in the horizontal direction W. In particular, the first incident lens portion 300 can have the multiple first light entry sections 310a, 310b, and 310c corresponding to the first light source portion 100, and the multiple first light entry sections 310a, 310b, and 310c can be distributed and arranged in the horizontal direction W. Therefore, the first incident lens portion 300 can be configured to have a comparatively large width. In contrast, since the first drop lens section 500 is configured such that the light introduced by the first incident lens section 300 is collected towards the central region of the first drop lens section 500 with respect to the horizontal direction W, the first drop lens section 500 can have a smaller overall width in the horizontal direction W.

[0091] The width of the second incident lens part 400 in the horizontal direction W can be smaller than the width of the second exhalation lens part 600 in the horizontal direction W. In particular, the second exhalation lens part 600 can be configured to have a greater width in the horizontal direction W than the second incident lens part 400 in order to form the peripheral light distribution by broadly scattering the light introduced by the second incident lens part 400 in the horizontal direction W.

[0092] The width of the first incidence surface 510 and the first emission surface 520 in the forward / backward direction L can be greater than the width of the second incidence surface 610 and the second emission surface 620 in the forward / backward direction L. In particular, the widths of the first incidence surface 510 and the first emission surface 520 in the forward / backward direction L must be sufficient to ensure adequate optical paths in the optical axis direction for the central light distribution to be formed. Therefore, the first incidence surface 510 and the first emission surface 520 can be designed to have a relatively large width in the forward / backward direction L. In contrast, the widths of the second incidence surface 610 and the second emission surface 620 in the forward / backward direction L are focused on light scattering to form the peripheral light distribution and provide relatively short optical paths.Therefore, the second incidence surface 610 and the second emission surface 620 can be designed to have a small width in the forward / backward direction L.
