Description

Technical Field

[0001] This disclosure relates to lamps for vehicles and vehicles including lamps. Background Technology

[0002] The appearance of lights installed in vehicles has become increasingly diverse, as aesthetics have been recognized as important. For example, designs with smoothly curved shapes have recently been incorporated into lighting fixtures. However, even with such designs, basic performance requirements must still be met. For instance, even with curved designs, the lights need to concentrate their illumination towards areas located in front of or behind the vehicle.

[0003] However, in the case of lamps with curved designs in the existing technology, the light emitted from the curved area does not propagate to the area in front of or behind the vehicle, but propagates laterally, which leads to reduced lamp performance and light loss. Utility Model Content

[0004] This disclosure aims to provide a luminaire with a curved design, which is configured such that light emitted from the curved area propagates to an area located in front of or behind a vehicle, thereby improving the performance of the luminaire and minimizing light loss.

[0005] One aspect of this disclosure provides a lamp for a vehicle, the lamp comprising: a plurality of light sources configured to emit light; and a lens portion disposed on one side of the plurality of light sources and configured such that light emitted from the plurality of light sources enters the lens portion, the plurality of light sources being disposed along a direction extending from the lens portion, and at least some of the plurality of light sources being disposed such that the optical axis AX of the plurality of light sources intersects with the normal Z of the region of the lens portion facing the plurality of light sources.

[0006] The lens portion may have an exit surface from which light emitted from the plurality of light sources exits, and at least some of the plurality of light sources are configured such that the optical axis AX of the plurality of light sources intersects with the normal Z of the exit surface in the region of the lens portion facing the plurality of light sources.

[0007] The lens portion may include a curved portion having a shape that bends in the extending direction of the lens portion, and multiple optical axes AX of at least some of the multiple light sources disposed in the region facing the curved portion may intersect the normal Z of the emitting surface in the region facing the multiple light sources of the curved portion.

[0009] The plurality of optical axes AX of at least some of the plurality of light sources disposed in the region facing the curved portion may intersect the normal Z of the emitting surface in the region of the curved portion facing the plurality of light sources.

[0010] The length of the second extension portion in the extension direction of the lens portion may be greater than the length of the first extension portion in the extension direction of the lens portion, and the plurality of light sources disposed facing the curved portion may be disposed such that when the optical axis AX is rotated relative to the normal Z in the direction toward the second extension portion, the optical axis AX of the plurality of light sources facing the curved portion intersects the normal Z of the emitting surface in the region of the curved portion facing the plurality of light sources.

[0011] At least some of the plurality of light sources facing the second extension portion can be configured such that the optical axis AX of the plurality of light sources facing the second extension portion is parallel to the normal Z of the emitting surface in the region of the second extension portion facing the plurality of light sources.

[0013] The degree to which the plurality of optical axes AX of at least some of the plurality of light sources arranged facing the curved portion rotate toward the second extension portion can increase as the distance from the second extension portion decreases.

[0014] The vehicle-mounted lamp may further include a light-collecting member disposed between the plurality of light sources and the emission surface and configured to collect light emitted from the plurality of light sources, wherein the lens portion includes: a lens body member having a space configured to accommodate the plurality of light sources and the light-collecting member; and an emission member disposed on one side of the lens body member and configured to define the emission surface.

[0015] A reflective surface having optical properties that reflect light emitted from the plurality of light sources can be formed on at least a portion of the inner surface of the lens body component.

[0016] The emitting component may include a light-diffusing component having optical properties that diffuse light emitted from the plurality of light sources.

[0017] At least a portion of the light-collecting component may be configured to be spaced apart from the inner surface of the lens body component.

[0018] The light-collecting component may have the following shape: the distance between the light-collecting component and the inner surface of the lens body component increases as the distance from the emitting component increases.

[0019] At least a portion of the light-collecting component may be configured to be tightly attached to the inner surface of the lens body component.

[0032] The following description, with reference to the accompanying drawings, describes the lamps and the vehicle according to the present disclosure.

[0033] Lighting for vehicles

[0034] Figure 1 This is a perspective view of a vehicle lamp according to the present disclosure. Figure 2 This is an enlarged view showing the periphery of the curved portion of the lens of a lamp for a vehicle according to the present disclosure. Figure 3 This is a perspective view showing an example of a light source disposed in a lamp for a vehicle according to the present disclosure.

[0035] Reference Figures 1 to 3The luminaire 10 for a vehicle according to this disclosure (hereinafter referred to as the "luminaire") may include: a plurality of light sources 100 configured to emit light; and a lens portion 200 disposed on one side of the plurality of light sources 100 and configured such that light emitted from the plurality of light sources 100 enters the lens portion 200. More specifically, the plurality of light sources 100 may be arranged to be spaced apart from each other in the direction in which the lens portion 200 extends. Light emitted from the light sources 100 may enter the lens portion 200 and then exit the lens portion 200, thereby forming a predetermined light distribution pattern or performing a predetermined function. For example, the luminaire 10 according to this disclosure may be a daytime running light (DRL) luminaire. However, various types of luminaires other than DRL luminaires may be used as the luminaire 10 according to this disclosure. Meanwhile, in this specification, the area of ​​the lens portion 200 from which light emitted from the light sources 100 exits is defined as the exiting surface.

[0036] Furthermore, according to this disclosure, at least some of the plurality of light sources 100 disposed in the luminaire 10 can be configured such that the optical axis AX of the light source 100 and the normal Z of the region of the lens portion 200 facing the light source 100 intersect each other but are not parallel to each other. More specifically, the lens portion 200 may have an exit surface 200a from which light emitted from the light source 100 exits. At least some of the plurality of light sources 100 can be configured such that the optical axis AX of the light source 100 and the normal Z of the exit surface 200a in the region of the lens portion 200 facing the light source 100 intersect each other.

[0037] As described above, the configuration in which the optical axis AX of the light source 100 and the normal Z of the emitting surface 200a in the region of the lens portion 200 facing the light source 100 intersect each other is designed to allow light emitted from the emitting surface in one region of the lens portion 200 to propagate in the direction necessary for the luminaire to function properly, thereby allowing the luminaire according to this disclosure to perform its function. Meanwhile, in this specification, the optical axis AX of the light source 100 can be defined as the central axis of the light beam emitted from the light source 100. The optical axis AX of the light source 100 can also be defined as the optical path through which the brightest beam of the light beam emitted from the light source 100 passes.

[0038] More specifically, the lens portion 200 according to this disclosure may include a curved portion 205 having a shape that is curved in the extending direction of the lens portion.

[0039] In this case, according to the present disclosure, the optical axes AX of at least some of the plurality of light sources 100 disposed in the region facing the curved portion 205 can be configured to intersect the normal Z of the emitting surface 200a in the region of the curved portion 205 facing the light source 100. In this case, the curvature characteristics of the curved portion 205 can prevent light loss of the luminaire caused when light emitted from the curved portion 205 propagates in an undesirable direction.

[0040] Continue to refer to Figures 1 to 3 In addition to the curved portion 205, the lens portion 200 may also include other portions. More specifically, the lens portion 200 may further include a first extension portion 210 and a second extension portion 220, wherein the first extension portion 210 is connected to a first side end of the curved portion 205 based on the extension direction of the lens portion, and the second extension portion 220 is connected to a second side end of the curved portion 205 based on the extension direction of the lens portion.

[0041] The first extension portion 210, the second extension portion 220, and the curved portion 205 can be distinguished based on the degree of curvature of their respective portions. More specifically, the curved portion 205 can be the most curved portion. That is, the degree of curvature of the curved portion 205 in the extension direction of the lens portion 200 can be greater than i) the degree of curvature of the first extension portion 210 in the extension direction of the lens portion 200 and ii) the degree of curvature of the second extension portion 220 in the extension direction of the lens portion 200.

[0042] Specifically, according to this disclosure, the optical axes AX of the plurality of light sources 100 disposed in the region facing the curved portion 205 can be configured to intersect with the normal Z of the emitting surface 200a in the region of the curved portion 205 facing the light source 100. As described above, since the curved portion 205 is the part with the greatest curvature in the lens portion 200, light loss may occur most significantly in the curved portion 205 due to the distortion of the direction of light emitted from the curved portion 205. Therefore, according to this disclosure, the optical axes AX of the light sources 100 disposed in the region facing the curved portion 205 can be configured to intersect with each other, thereby minimizing the aforementioned light loss.

[0043] Furthermore, according to this disclosure, the length of the second extension portion 220 in the extending direction of the lens portion 200 can be longer than the length of the first extension portion 210 in the extending direction of the lens portion 200. In this case, according to this disclosure, the plurality of light sources 100 provided facing the curved portion 205 can be configured such that when the optical axis AX is rotated relative to the normal Z in the direction toward the second extension portion 220, the optical axis AX of the light source 100 facing the curved portion 205 can intersect the normal Z of the emitting surface 200a in the region of the curved portion 205 facing the light source 100. In the luminaire 10 according to this disclosure, the second extension portion 220 can be the main light-emitting surface of the luminaire 10 according to this disclosure. Therefore, according to this disclosure, the optical axis AX of the light source 100 facing the curved portion 205 is biased toward the second extension portion 220, so that light emitted from the curved portion 205 can propagate to the second extension portion 220 of the main light-emitting surface. For example, the optical axes AX of the plurality of light sources 100 provided facing the curved portion 205 can be arranged parallel to each other. However, in another example, the degree to which the optical axis AX of the plurality of light sources 100 arranged facing the curved portion 205 rotates toward the second extension portion 220 can increase as the distance from the second extension portion 220 decreases.

[0044] Furthermore, according to this disclosure, at least some of the plurality of light sources 100 facing the second extension portion 220 can be configured such that the optical axis AX of the light source facing the second extension portion 220 is parallel to the normal Z of the exit surface 200a in the region of the second extension portion 220 facing the light source 100. For example, the plurality of light sources 100 facing the second extension portion 220 can each be configured such that the optical axis AX of the light source facing the second extension portion 220 is parallel to the normal Z of the exit surface 200a in the region of the second extension portion 220 facing the light source 100.

[0045] Figure 4 This is an enlarged perspective view showing an example of a lamp for a vehicle according to the present disclosure. Figure 5 It is shown Figure 4 A view of the cross-sectional structure. Figure 6 This is an enlarged perspective view showing another example of a lighting fixture for a vehicle according to the present disclosure. Figure 7 It is shown Figure 6 A view of the cross-sectional structure.

[0046] Reference Figures 4 to 7The luminaire 10 according to this disclosure may further include a light-collecting member 300 disposed between the light source 100 and the emission surface 200a, and configured to collect light emitted from the light source 100. Furthermore, the lens portion 200 may include a lens body member 230 and an emission member 240. The lens body member 230 has a space configured to accommodate the light source 100 and the light-collecting member 300, and the emission member 240 is disposed on one side of the lens body member 230 and configured to define the emission surface 200a. The lens body member 230 and the emission member 240 may extend over a curved portion 205, a first extension portion 210, and a second extension portion 220. In this case, a reflective surface having optical properties that reflect light emitted from the light source 100 may be formed on at least a portion of the inner surface of the lens body member 230. For example, the reflective surface may be formed on the entire inner surface of the lens body member 230.

[0047] Meanwhile, in order to uniformly diffuse the light emitted from the lens section 200 to the outside, the emitting member 240 may be or include a light diffusing member having optical properties that diffuse the light emitted from the light source 100.

[0048] In this case, such as Figure 4 and Figure 5 As shown, according to one example of this disclosure, at least a portion of the light collecting member 300 may be configured to be spaced apart from the inner surface of the lens body member 230. More specifically, the light collecting member 300 may have a shape such that the distance between the light collecting member 300 and the inner surface of the lens body member 230 increases as the distance from the emitting member 240 increases (i.e., as the distance from the light source decreases).

[0049] On the contrary, such as Figure 6 and Figure 7 As shown, according to another example of this disclosure, at least a portion of the light-collecting member 300 may be configured to be tightly attached to the inner surface of the lens body member 230. More specifically, the entire region of the light-collecting member 300 facing the inner surface of the lens body member 230 may be configured to be tightly attached to the inner surface of the lens body member 230.

Figures 1 to 7 The description of the lamps for vehicles according to this disclosure can be applied in its entirety to the description of lamps for vehicles installed in vehicles according to this disclosure.

[0053] Meanwhile, the lens portion 200 of the lamp 10 installed in the vehicle 1 according to the present disclosure may include a curved portion 205 having a shape that is curved in the extending direction of the lens portion, a first extension portion 210 connected to a first side end of the curved portion 205 based on the extending direction of the lens portion 200, and a second extension portion 220 connected to a second side end of the curved portion 205 based on the extending direction of the lens portion 200.

[0054] Meanwhile, the lamps installed in the vehicle according to this disclosure can be installed on the front or rear side of the vehicle 1, and the second extension 220 of the lens portion 200 can be configured to face the front or rear side of the vehicle. In this case, the plurality of light sources 100 provided facing the curved portion 205 can be configured such that, when the optical axis AX is rotated relative to the normal Z in the direction toward the second extension 220, the optical axis AX of the light source 100 facing the curved portion 205 can intersect the normal Z of the emitting surface 200a in the region of the curved portion 205 facing the light source 100.
