Abstract
Description
Technical Field
[0001] This disclosure relates to a light-emitting module for a vehicle and a lamp device including the light-emitting module. Background Technology
[0002] The statements in this section are provided only as background information in connection with this disclosure and do not constitute prior art.
[0003] Vehicle lights are lights configured to emit light forward so that the vehicle can drive safely. Vehicle lights include headlights, taillights, etc. Headlights include high beams, low beams, turn signals, side marker lights, and other components.
[0004] The design of such headlights is considered crucial to determining vehicle design characteristics, and the technology used to achieve thin headlights that provide uniform illumination has become important.
[0005] Figure 1 and Figure 2 A vehicle lighting device based on the prior art is shown.
[0006] refer to Figure 1 and Figure 2 According to the prior art, the vehicle lighting device includes multiple light-emitting modules M. In particular, the multiple light-emitting modules M are arranged along the forward / rearward and left / right directions of the vehicle, and are spaced apart from each other in the left / right direction.
[0007] However, we have found that lamp devices comprising multiple light-emitting lamps M exhibit discontinuities because the illuminating areas are separated from each other due to the housing and spacing. Covering the light-emitting module with a lens that scatters or diffuses light to counteract these discontinuities may not be suitable for low-beam headlights with a projecting shape.
[0008] The above description of the background art is only for the purpose of helping to understand the background of this disclosure and should not be regarded by those skilled in the art as corresponding to known prior art. Summary of the Invention
[0009] The light-emitting module for a vehicle according to the present disclosure includes: a light source configured to generate light during its operation; a condenser lens located in front of the light source in the direction of propagation of the light generated by the light source and configured to change the propagation direction of the input light; and a multifaceted lens located in front of the condenser lens in the direction of propagation of the light generated by the light source, and including a rear surface and multiple portions, wherein light passing through the condenser lens is input through the rear surface, and wherein the front surfaces of the multiple portions have different protrusion heights.
[0010] Multiple parts of the multi-faceted lens can protrude sequentially to the front side along the vehicle's left / right or up / down direction.
[0011] The corresponding illumination areas of the multiple parts of the multifaceted lens can be different.
[0012] As the multiple parts of the multifaceted lens reach the inside along the vehicle's left / right direction, they can protrude higher towards the front.
[0013] As the multiple sections of the multifaceted lens reach the outer edge along the vehicle's left / right direction, they can protrude lower towards the front.
[0014] Multiple parts of a multifaceted lens can be stepped with adjacent parts in the forward / backward direction.
[0015] Multiple parts of a multifaceted lens can be configured to face parallel directions.
[0016] The light-emitting module may also include a housing that partially surrounds the outer surface of the polygonal lens, and the polygonal lens may extend from the front side of the housing to the outside to cover the front surface of the housing from the front side.
[0017] The housing can be configured to partially or entirely overlap with the housing of the adjacent light-emitting module in the left / right direction, and can be configured to be spaced apart from the housing of the adjacent light-emitting module in the forward / backward direction.
[0018] The shell can be formed by a frame of transparent material through which light can pass.
[0019] A condenser lens can cause light generated by a light source to propagate in parallel or be refracted to converge the light.
[0020] A condenser lens can completely reflect the input light on its inner surface and can be integrated with a multi-faceted lens.
[0021] The lighting device for a vehicle according to this disclosure is a lighting device including light-emitting modules for a vehicle, wherein multiple light-emitting modules are provided and the multiple light-emitting modules are arranged in the left / right direction of the vehicle.
[0022] The multifaceted lens in the light-emitting module can be spaced apart from the multifaceted lenses of adjacent light-emitting modules in the forward / backward direction.
[0023] The multifaceted lens of the light-emitting module can be configured to protrude further forward than the light-emitting module positioned on the relatively outer side along the left / right direction of the vehicle.
[0024] Multiple portions of the multifaceted lens of the light-emitting module can protrude further towards the relatively forward side than multiple portions of the multifaceted lens of the light-emitting module positioned on the relatively outer side along the left / right direction of the vehicle.
[0025] The stepped portion between multiple parts of the multifaceted lens of the light-emitting module can be smaller than the stepped portion between multiple parts of the multifaceted lens of the light-emitting module located on the relatively outer side in the left / right direction of the vehicle.
[0026] According to this disclosure, the advantages of the light-emitting module for a vehicle and the lamp device including the light-emitting module are that the continuity of the illumination area with respect to the light-emitting module is improved, and the discontinuity between multiple light-emitting modules forming the lamp device is reduced accordingly.

[0044] In the following description, exemplary forms of this disclosure will be described in detail with reference to the accompanying drawings. The same or similar reference numerals presented in the drawings denote the same or similar elements.
[0045] Figure 3An exploded perspective view of a light-emitting module M for a vehicle according to one form of the present disclosure is shown. Figure 4 A perspective view of a multifaceted lens 30 according to this disclosure is shown.
[0046] refer to Figure 3 and Figure 4 According to one form of the present disclosure, a light-emitting module M for a vehicle includes: a light source 10 configured to generate light during its operation; a condenser lens 20 located in front of the light source 10 in the direction of propagation of the light generated by the light source 10 and configured to change the direction of propagation of the input light; and a faceted lens 30 located in front of the condenser lens 20 in the direction of propagation of the light generated by the light source 10, light passing through the condenser lens 20 being input to the faceted lens 30 through its rear surface, and the faceted lens 30 including a plurality of portions 31 having different protrusion heights on their front surfaces.
[0047] The light source 10 may include a light-emitting diode (LED) or an organic light-emitting diode (OLED). Alternatively, the light source 10 may be an LED array module (LAM).
[0048] The light source 10 can be coupled to a substrate 11 that controls the supply of various currents. For example, the substrate can be a PCB substrate, but this disclosure is not limited thereto.
[0049] The light source 10 can generate light at a specific point and can generate light in various directions. The generation direction and propagation direction of the light generated by the light source 10 refer to the directions corresponding to the effective illumination range of the light source 10, and can be the opposite direction to the direction in which the light is blocked by the substrate or the like.
[0050] In particular, when a light-emitting module M for a vehicle according to one form of the present disclosure is installed on a vehicle, the light source 10 can generate light toward the front of the vehicle or propagate light to the front of the vehicle.
[0051] The condenser lens 20 can be located in front of the light source 10 and can propagate light input to the rear side by reflecting light. In particular, the condenser lens 20 can change the propagation direction of the light generated by the light source 10. In particular, the condenser lens 20 can guide the light generated by the first light source 10 so that the light is converged.
[0052] Here, the concept of light convergence means that the direction of light propagation is changed to the direction in which light is converged to a focal point. The case where light propagating in the dispersion direction travels parallel to the light also falls under the category of light being changed to a convergent direction.
[0053] The multifaceted lens (MFL) 30 is located in front of the condenser lens 20, and the light generated by the light source 10 that propagates parallel through the condenser lens 20 can be refracted in a specific direction. The light passing through the multifaceted lens 30 can propagate to a preset illumination area.
[0054] Light that has passed through the condenser lens 20 located behind the polygonal lens 30 can be input through the rear surface of the condenser lens 20 and can also be propagated through the front surface of the condenser lens 20.
[0055] In detail, the faceted lens 30 may include a plurality of portions 31 on its front surface. In particular, the protrusion heights of the plurality of portions 31 may be different. That is, the portions 31 included in the faceted lens 30 may be positioned to protrude to the front side of adjacent portions 31 or to be recessed to the rear side of adjacent portions 31.
[0056] Figure 5 and Figure 6 A front view of the multifaceted lens 30 in various forms according to this disclosure is shown.
[0057] Further reference Figure 5 and Figure 6 Multiple portions 31 of the multi-faceted lens 30 protrude sequentially to the front side along the left / right or up / down direction of the vehicle.
[0058] In detail, in the multifaceted lens 30, multiple portions 31 can be arranged in an upward / downward direction or a leftward / rightward direction. The multiple portions 31 of the multifaceted lens 30 can protrude sequentially to the front side as they reach the left or right side in a leftward / rightward direction, or they can protrude sequentially to the front side as they reach the upper or lower side in an upward / downward direction.
[0059] like Figure 5 As shown, when the multiple portions 31 of the multifaceted lens 30 reach the center direction and the lower side along the left / right direction of the vehicle, they can sequentially protrude to the front side. In particular, the portion 31_H1 located in the center direction and the lower corner of the vehicle can protrude to the foremost side, while the portion 31_L1 located in the outward direction and the upper corner of the vehicle can be recessed to the rearmost side.
[0060] In addition, such as Figure 6 As shown, when the multiple portions 31 of the multifaceted lens 30 reach the center direction and the upper side along the left / right direction of the vehicle, they can sequentially protrude to the front side. In particular, the portion 31_H2 located in the center direction and the upper corner of the vehicle can protrude to the foremost side, while the portion 31_L2 located in the outward direction and the lower corner of the vehicle can be recessed to the rearmost side.
[0061] The illumination areas of the multiple parts 31 of the multifaceted lens 30 may differ.
[0062] Light input to the rear surface of the polygonal lens 30 propagates through multiple portions forming the front surface to define an illumination area, and the illumination area can be different in the left / right or up / down direction. The portions of the illumination area can overlap each other.
[0063] As the multiple portions 31 of the multifaceted lens 30 reach the inner side along the left / right direction of the vehicle, they can protrude higher towards the front side.
[0064] As the multiple portions 31 of the multifaceted lens 30 reach the outer side along the left / right direction of the vehicle, they can protrude lower towards the front side.
[0065] In detail, multiple portions 31 of the multifaceted lens 30 can gradually protrude further forward as they reach the center of the vehicle in the left / right direction. This arrangement can be made along the outer periphery C of the vehicle's headlights.
[0066] Multiple portions 31 of the multifaceted lens 30 can be stepped with adjacent portions 31 in the forward / backward direction.
[0067] In other words, part 31 of the multifaceted lens 30 is discontinuous with adjacent part 31 in the left / right or up / down direction, and may be stepped with each other in the forward / backward direction.
[0068] As one form, multiple portions 31 of the multifaceted lens 30 can be configured to face a parallel direction.
[0069] In particular, the multiple portions 31 can be configured to face the parallel direction in a state where they are cut in the intersecting direction, so that light propagating through the multiple portions 31 can also propagate in the parallel direction.
[0070] As another form, some of the multiple sections 31 of the multifaceted lens 30 can be configured to face different directions. Therefore, the intensity of light in the illumination area of the light-emitting module M can be uniformly set by spreading the light in various directions to disperse the light.
[0071] Figure 7 A diagram is shown of a light-emitting module M for a vehicle and a lamp device including the light-emitting module, according to one form of the present disclosure.
[0072] Further reference Figure 7 The light-emitting module may also include a housing that partially surrounds the outer surface of the polygonal lens 30, wherein the polygonal lens 30 may extend from the front side of the housing 40 to the outside to cover the front surface of the housing 40 from the front side.
[0073] The housing 40 may partially surround the outer surface of the faceted lens 30, and may also surround the light source 10 and the condenser lens 20 from the outside. In particular, the housing 40 may surround portions of the left and right surfaces of the faceted lens 30 from the outside.
[0074] Specifically, the housing 40 may surround the outer surface of the polygonal lens 30 at the rear end of the polygonal lens 30, and the outer surface of the front end of the polygonal lens 30 may be exposed to the outside of the housing 40. The front end of the polygonal lens 30 may be extended to the outside, so that when viewed from the front, the polygonal lens 30 may be extended to the front side of the front surface of the housing 40.
[0075] Therefore, the spacing between adjacent light-emitting modules M caused by the thickness of the housing 40 (frame) can be minimized.
[0076] Furthermore, the housing 40 may be configured such that a portion or the entire area of the housing 40 overlaps with the housing of the adjacent light-emitting module M in the left / right direction, and may be configured to be spaced apart from the housing of the adjacent light-emitting module M in the forward / backward direction.
[0077] Therefore, the continuity of the light-emitting surface can be improved by modifying the light-shielding portion set between adjacent light-emitting modules M.
[0078] Furthermore, the housing 40 can be formed of a frame made of transparent material through which light passes. Therefore, the continuity of the light-emitting surface can be improved by modifying the light-shielding portion disposed between adjacent light-emitting modules M.
[0079] The condenser lens 20 can refract the light generated by the light source 10, so that the light propagates in parallel or converges.
[0080] In one embodiment, the condenser lens 20 may be a projection lens that protrudes from one or the opposite side, or it may be a Fresnel lens that is compressed in the planar direction.
[0081] In another form, the condenser lens 20 may be a total internal reflection (TIR) lens, which completely reflects the light input to the inside on its inner surface.
[0082] Figure 8 and Figure 9 An integrated lens 20, 30 according to the present disclosure is shown, wherein the condenser lens 20 and the multifaceted lens 30 are integrated together.
[0083] refer to Figure 8 and Figure 9 The condenser lens 20 can completely reflect the input light from its inner surface and can be integrated with the multifaceted lens 30.
[0084] The rear end of the integrated lenses 20 and 30 can be a condenser lens 20, which completely reflects the light input into the interior so that the light propagates to the front side. The light passing through the rear end of the integrated lenses 20 and 30 can be parallel light propagating in a parallel direction.
[0085] The front end of the integrated lenses 20 and 30 can be a multi-faceted lens 30 comprising multiple parts 31.
[0086] like Figure 9 As shown, the integrated lenses 20 and 30 can completely reflect the light input into them to their inner surface to change the direction of light propagation.
[0087] Figure 10 A perspective view of a lighting device for a vehicle according to this disclosure is shown. Figure 11 A diagram showing one form of a lighting device for a vehicle according to this disclosure is shown.
[0088] refer to Figure 10 and Figure 11 According to one form of the present disclosure, a lighting device for a vehicle may be provided with a plurality of light-emitting modules M, and the plurality of light-emitting modules M may be arranged along the left / right direction of the vehicle.
[0089] In detail, the multifaceted lens 30 of the light-emitting module M can be spaced apart from the multifaceted lens 30 of the adjacent light-emitting module M in the forward / backward direction.
[0090] The multifaceted lens 30 of the light-emitting module M may protrude further forward than the multifaceted lens 30 of the light-emitting module M disposed on the outer side in the left / right direction along the vehicle. Conversely, the multifaceted lens 30 of the light-emitting module M may be disposed on the rear side of the multifaceted lens 30 of the light-emitting module M in the direction adjacent to the center of the vehicle, so as to be relatively recessed.
[0091] In other words, the multiple light-emitting modules M and the multifaceted lens 30 included therein can be recessed to the rear as they reach the outer side in the left / right direction of the vehicle, and can be configured to protrude to the front as they reach the center direction of the vehicle.
[0092] Furthermore, multiple portions 31 of the polygonal lens 30 included in the light-emitting module M may protrude further than multiple portions 31 of the polygonal lens 30 included in the light-emitting module M which are disposed on the relatively outer side in the left / right direction of the vehicle.
[0093] Multiple portions 31 of the multifaceted lens 30 can be arranged to be spaced apart from each other in a forward / rearward direction. In particular, portions 31 of the multifaceted lens 30 included in the light-emitting module M can protrude forward as they extend in the central direction along the left / right direction of the vehicle.
[0094] Meanwhile, among the multiple portions 31 of the multifaceted lens 3 of the light-emitting module M, the portion 31 that protrudes lowest to the front can be positioned further forward than the portion 31 that protrudes highest to the front among the multiple portions 31 of the multifaceted lens 30 of the light-emitting module M that is positioned on the outer side along the left / right direction of the vehicle.
[0095] Furthermore, the multiple portions 31 of the multifaceted lens 30 included in the light-emitting module M can be arranged in a stepped shape in the forward / rearward direction of the vehicle. Additionally, the stepped portions of the multiple light-emitting modules M disposed between the multiple portions 31 of the multifaceted lens 30 can be different.
[0096] In one embodiment, the plurality of stepped portions X1 between the plurality of portions 31 of the multifaceted lens 30 included in the light-emitting module M may be smaller than the stepped portions X2 between the plurality of portions 31 of the multifaceted lens 30 included in the light-emitting module M disposed on the opposite outer side in the left / right direction along the vehicle.
[0097] In detail, multiple light-emitting modules M can be arranged along the left / right direction of the vehicle, and can be arranged on the rear side as they reach the outside of the vehicle. In particular, the spacing between adjacent light-emitting modules M in the forward / rearward direction can increase as they reach the outside of the vehicle.
[0098] Furthermore, since the spacing between adjacent light-emitting modules M in the forward / backward direction increases as they reach the outer side, the stepped portions X1 and X2 between the multiple parts 31 of the multifaceted lens 30 of the light-emitting module M can also gradually increase.
[0099] Furthermore, in the multiple portions 31 of the multifaceted lens 30 of the light-emitting module M, the sum of the stepped portions arranged between the portions 31 in the left / right direction may be less than the entire height of the multifaceted lens 30 in the forward / backward direction.
[0100] Furthermore, in the multiple portions 31 of the multifaceted lens 30 of the light-emitting module M, the sum of the stepped portions arranged between the portions 31 in the left / right direction can be less than the height difference between the corresponding light-emitting module M and the adjacent light-emitting modules M in the forward / backward direction.
[0101] Although this disclosure has been described and shown in particular form, it will be apparent to those skilled in the art that various improvements and modifications may be made to this disclosure without departing from the technical spirit of the disclosure as defined by the appended claims.
