Description

Technical Field

[0001] This invention relates to a lighting module and a vehicle lighting fixture including the lighting module. More specifically, this invention relates to a lighting module capable of forming a uniform appearance and a vehicle lighting fixture including the lighting module. Background Technology

[0002] Typically, vehicles are equipped with a variety of lights that provide illumination for easy identification of objects around the vehicle when driving at night and signals to inform other vehicles or pedestrians of the vehicle's driving status.

[0003] For example, headlights and fog lights are mainly designed for illumination, while turn signals, taillights, and brake lights are mainly designed for signaling. Regulations stipulate the standards and specifications for their installation to ensure that each light fixture can fully perform its respective function.

[0004] Recently, not only the functional aspects of vehicle lighting, which are fundamental to ensuring driver visibility and thus aiding safe driving, but also the aesthetic aspects that consumers perceive through enhanced design, have a significant impact on their decisions to purchase a vehicle.

[0005] To this end, vehicle lights are equipped with multiple light modules to give them a slimmer shape, thereby enabling them to achieve a slim shape while forming the best beam pattern.

[0006] When a vehicle's lighting fixture is equipped with multiple lighting modules, these modules form different beam patterns. Furthermore, the lighting modules that form different beam patterns need to have different illumination directions, making it difficult to achieve a unified overall appearance.

[0007] Therefore, a solution is needed that allows multiple lighting modules to form a unified overall appearance while also creating distinct beam patterns for each other.

[0026] The optical component may include: an incident surface for light reflected by the reflector to enter; and an exit surface for light incident on the incident surface to exit, wherein the curvature of at least one of the incident surface and the exit surface of one of the plurality of lamp modules may be different from that of the others.

[0061] Reference Figures 1 to 5 According to an embodiment of the present invention, the lighting module 100 may include a light source 110, an optical part 120 and a reflective part 130.

[0062] In an embodiment of the present invention, the lighting module 100 is described as follows: when a vehicle enters a curve or changes its route by turning left or right at an intersection, it serves as a turning assist light that illuminates the side with reference to the front of the vehicle to ensure the driver's visibility. However, it is not limited to this. The lighting module 100 of the present invention can be used not only as a turning assist light, but also as various lights installed on a vehicle, such as headlights, taillights, daytime running lights, brake lights, turn signals, reversing lights, and signal lights.

[0063] The light source unit 110 may include a light source chip 111, which includes at least one light source that generates light with a light quantity or color suitable for the beam pattern formed by the lamp module 100 of the present invention.

[0064] The light-emitting surface 111a of the light source chip 111 can be formed by the light-emitting surface of at least one light source. In the embodiments of the present invention, the case in which the light-emitting surface 111a of the light source chip 111 has a rectangular shape is described as an example, but it is not limited thereto. The shape of the light-emitting surface 111a of the light source chip 111 can be varied.

[0065] In the embodiments of the present invention, the case in which a semiconductor light-emitting element such as a light-emitting diode (LED) is used as at least one light source is described as an example, but it is not limited thereto. At least one light source can be not only a light-emitting diode (LED), but also various types of light sources such as a laser diode (LD) or a bulb.

[0066] The light source chip 111 can be disposed on a substrate 112 that is in thermal contact with the heat sink 140. The substrate 112 can not only be provided with the light source chip 111, but also with various components such as a connector 113 for power supply or operation control of the light source chip 111.

[0067] At this time, when light is generated from the light source chip 111, high-temperature heat is also generated. When the high-temperature heat causes the temperature to rise, the light-emitting performance of the light source chip 111 drops sharply. Therefore, the light source part 110 is configured to be in thermal contact with the heat dissipation part 140 in order to achieve rapid heat dissipation and prevent the light-emitting performance of the light source chip 111 from dropping. In addition, if necessary, a heat dissipation device such as a cooling fan can be added while using the heat dissipation part 140.

[0068] The optical section 120 allows light generated from the light source chip 111 to be transmitted, thereby forming a beam pattern suitable for the use of the lamp module 100 of the present invention.

[0069] In an embodiment of the present invention, the optical unit 120 is configured such that the optical axis Ax is parallel to the front-back direction. This is to ensure that the lamp module 100 of the present invention and other lamp modules that form beam patterns different from those of the lamp module 100 of the present invention have a unified appearance. A detailed description of this will be given later.

[0070] In an embodiment of the present invention, the case where the lighting module 100 is used as a turn assist light will be described as an example. Therefore, as follows: Figure 6As shown, the optical unit 120 can make the incident surface 121 have a concave curved shape so that the light incident on the incident surface 121 can be refracted to the side at a larger refraction angle, and the curvature of the incident surface 121 can be varied according to the refraction angle required by the optical unit 120.

[0071] Furthermore, if the required angle of refraction of the incident surface 121 is not met, the exit surface 122 is made to have a convex curved surface shape, thereby satisfying the required angle of refraction.

[0072] At this time, the incident surface 121 can be formed to have a greater curvature than the exit surface 122. This is because when viewed from the outside, the exit surface 122, as a surface that can be confirmed, tends to be difficult to adjust in order to form the desired image. Therefore, adjusting the curvature of the incident surface 121 is more effective than adjusting the curvature of the exit surface 122, thereby forming the incident surface 121 to have a greater curvature than the exit surface 122.

[0073] The reflector 130 can reflect the light generated from the light source chip 111 so that the light travels towards the optical section 120.

[0074] That is, in the embodiment of the present invention, the case in which the light-emitting surface 111a of the light source chip 111 is configured to emit light upwards is described as an example. Therefore, the reflective part 130 reflects the light emitted upwards from the light source chip 111 so that the light travels to the optical part 120 located in front of the light source chip 111.

[0075] The aforementioned lamp module 100 is configured such that the light source chip 111 is spaced laterally with the optical axis Ax of the optical section 120 as a reference. Thus, the reflector 130 can be configured such that the central axis C is tilted at a predetermined angle with the optical axis Ax of the optical section 120 as a reference, so that the light generated from the light source chip 111 is incident on the optical section 120.

[0076] In other words, normally, the light source chip 111 is located on the first focal point F1 of the reflector 130. The reflector 130 can be formed with the central axis C as a reference to be approximately symmetrical on both sides, so that the light reflected by the reflector 130 is focused at the second focal point F2 located in front of the first focal point F1. When the center of the light source chip 111 (i.e., the center of the light-emitting surface 111a) is located on the optical axis Ax of the optical section 120, the optical axis Ax of the optical section 120 is the same as the central axis C of the reflector 130. Thus, the reflector 130 is formed with the optical axis Ax of the optical section 120 as a reference to be approximately symmetrical on both sides. Conversely, in the embodiment of the present invention, since the light source chip 111 is set to be spaced apart laterally by a predetermined distance with the optical axis Ax of the optical section 120 as a reference, the central axis C of the reflector 130 is set to be tilted at a predetermined angle with the optical axis Ax of the optical section 120 as a reference.

[0077] As described above, when the light source chip 111 is configured to be spaced laterally at a predetermined distance based on the optical axis Ax of the optical section 120, such as Figure 7 As shown, the center line Pc of the beam pattern P formed by the lamp module 100 of the present invention is set to move laterally with reference to the center of the front of the vehicle (i.e., the intersection point Po of the HH line and VV). Therefore, the lamp module 100 of the present invention can be used as a turn assist lamp.

[0078] That is, depending on the distance between the light source chip 111 and the optical axis Ax of the optical section 120, the tilt angle of the central axis C of the reflector 130 of the optical section 120, which is used to allow the light generated from the light source chip 111 to be incident on, can be different, and depending on the distance between the light source chip 111 and the tilt angle of the reflector 130, the position of the center line Pc of the beam pattern P can be different.

[0079] At this point, it can be seen Figure 7 The upper boundary line of the beam pattern P is located below the HH line, and the light is formed by shining on the lower side of the upper boundary line. This is because when the upper boundary line of the beam pattern P is above the HH line, it may dazzle the driver of the vehicle in front, such as a vehicle traveling ahead or an oncoming vehicle.

[0080] The reflector 130 includes an effective reflective surface 131 with a curved shape and a front reflective surface 132 formed at the front end of the effective reflective surface 131. The effective reflective surface 131 can actually form a beam pattern suitable for the use of the vehicle lamp of the present invention. The front reflective surface 132 can have a rolled texture structure 132a formed on its inner side to prevent glare from the beam pattern formed by the vehicle lamp of the present invention.

[0081] In addition, the light reflected by the reflector 130 can be guided through the guide hole 151 of the light guide 150, such as the frame that is combined with the front of the heat dissipation section 140, and thus transmitted to the optical section 120. The light guide 150 may be combined with a bracket 160 for fixing the position of the optical section 120.

[0082] Through holes 152 and 162 are formed in the light guide section 150 and the bracket 160, respectively. The through holes 152 and 162 allow the connecting parts 142, such as bolts, to pass through the connecting groove 141 formed in front of the heat dissipation section 140.

[0083] At this time, the bracket 160 may have an opening 161 that exposes the emission surface 122 of the optical section 120. In the embodiment of the present invention, not only the emission surface 122 is exposed, but at least a portion of the side surface 123 between the incident surface 121 and the emission surface 122 of the optical section 120 may also be exposed. This is so that the beam pattern has appropriate light distribution characteristics by means of the lamp module 100 of the present invention.

[0084] That is, such as Figure 8 As shown, when the side 123 of the optical unit 120 is blocked by the bracket 160, a region A1 will be generated where the center of the upper boundary line of the beam pattern droops downward relative to the lower side, which may reduce the driver's field of vision. Therefore, in the embodiment of the present invention, the side 123 of the optical unit 120 is exposed to prevent the driver's field of vision from being reduced.

[0085] Furthermore, at least one optical pattern 123a for light diffusion or scattering can be formed on at least a portion of the side surface 123 of the optical section 120. Such optical pattern 123a can prevent glare caused by light emitted from the side surface 123 of the optical section 120 and can improve the diffusion characteristics of the beam pattern.

[0086] In an embodiment of the present invention, at least one optical pattern 123a includes a plurality of optical patterns 123a. The plurality of optical patterns 123a have the same spacing and are formed along a diagonal direction by tilting at a predetermined angle with the optical axis of the optical part as a reference, thereby improving diffusion characteristics.

[0087] For example, with the optical axis Ax of the optical section 120 as a reference, multiple optical patterns 123a can be formed along the diagonal direction, so that the greater the distance between them to the side, the further back they are located. As a result, light can be further diffused by the multiple optical patterns 123a, thereby improving the diffusion characteristics.

[0088] In embodiments of the present invention, an example is given of a plurality of optical patterns 123a formed diagonally with a predetermined angle tilted relative to the optical axis Ax of the optical unit 120. However, this is not a limitation; the overall outline of the plurality of optical patterns 123a may have a diagonal direction while being formed along a straight line, a curve, or a combination thereof. Furthermore, the light source chip 111 is typically configured such that the center line R connecting the centers of the two opposing ends of the light-emitting surface 111a coincides with the center axis C of the reflective portion 130. However, in embodiments of the present invention, such as... Figure 9As shown, the center line R of the light source chip 111 and the center axis C of the reflector 130 can be set to be tilted at different angles relative to each other with the optical axis Ax of the optical section 120 as a reference. This is because when the center line R of the light source chip 111 is set to be consistent with the center axis C of the reflector 130, a part of the upper boundary line of the beam pattern is formed into an area A2 that protrudes upward, which may produce dazzling glare for the driver of the vehicle in front.

[0089] As described above, the lighting module 100 of the present invention can vary the light distribution characteristics (i.e., such as the formation position of the beam pattern, the shape of the beam pattern, the size of the beam pattern, etc.) of the beam pattern formed by the lighting module 100 of the present invention according to the spacing distance of the light source chips 111, the tilt angle of the center line R of the light-emitting surface 111a of the light source chip 111, the tilt angle of the central axis C of the reflector 130, and the curvature of at least one of the incident surface 121 and the emission surface 122 of the optical part 120.

[0090] Figure 10 This is a front view illustrating a vehicle lamp according to an embodiment of the present invention.

[0091] Reference Figure 10 According to an embodiment of the present invention, a vehicle lamp 200 may include a plurality of lamp modules 210, 220, 230, 240 arranged along at least one direction, and different portions of the plurality of lamp modules 210, 220, 230, 240 may form different beam patterns.

[0092] In the embodiments of the present invention, the case in which multiple lamp modules 210, 220, 230, and 240 are arranged in the vertical direction is used as an example for explanation, but it is not limited thereto. The multiple lamp modules 210, 220, 230, and 240 can be arranged in the horizontal direction, the vertical direction, or a combination thereof.

[0093] Multiple lighting modules 210, 220, 230, and 240 can be divided into multiple groups G1 and G2. In an embodiment of the present invention, the multiple groups G1 and G2 include a first group G1 used as a headlight and a second group G2 used as a turn assist lamp. The case in which the first group G1 is formed as a low beam pattern will be described as an example.

[0094] Dividing the multiple lamp modules 210, 220, 230, 240 into a first group G1 and a second group G2 is merely one example to aid in understanding the present invention and is not limited thereto. Depending on the type or number of beam patterns formed by the vehicle lamp 200 of the present invention, the number or group of lamp modules included in the vehicle lamp 200 of the present invention can be varied.

[0095] The lighting module 240 included in the second group G2 of the first group G1 and the second group G2 described above is used as a turn assist light in the same way as the lighting module 100 of the above embodiment, so a detailed description of its function is omitted.

[0096] At this time, unlike the second group G2, the first group G1 is used as a headlight. However, the center line R of the light source chip 111 of the lamp module 100 in the above embodiment and the center axis C of the reflector 130 are tilted at different angles relative to the optical axis Ax of the optical section 120, so that a low beam pattern can be formed.

[0097] For example, such as Figure 11 As shown, by making the spacing distance between the light source chips of each of the lamp modules 210, 220, and 230 belonging to the first group G1 different from each other, and the tangent angle of the center line R of the light source chip and the center axis C of the reflector relative to the optical axis Ax of the optical part, sub-beam patterns LP1, LP2, and LP3 for forming part of the low beam pattern can be formed respectively, and the sub-beam patterns LP1, LP2, and LP3 can be combined with each other to form the low beam pattern LP.

[0098] exist Figure 11 The following example illustrates this: the spacing direction and distance of the light source chips of each of the luminaire modules 210, 220, and 230 belonging to the first group G1, and the angle of inclination of the center line R of the light source chip and the center axis C of the reflector with reference to the optical axis Ax of the optical unit are different from each other. This makes the positions of the sub-beam patterns LP1, LP2, and LP3 formed by each of the luminaire modules 210, 220, and 230 belonging to the first group G1 different from each other. However, this is not limited to this. The light distribution characteristics of the sub-beam patterns LP1, LP2, and LP3 formed by each of the luminaire modules 210, 220, and 230 belonging to the first group G1 can also be made different by making the curvature of at least one of the incident surface and the emission surface of the optical unit different.

[0099] In addition, Figure 10 In this example, the side of the optical part of the lamp module belonging to the second group G2 is exposed while the side of the optical part of the lamp module belonging to the first group G1 is not exposed. However, this is only one example to help understand the present invention and is not limited thereto. Depending on the beam pattern formed by the first group G1, the side of the optical part of the lamp module belonging to the first group G1 may also be exposed.

[0100] For example, if one of the lighting modules 210, 220, and 230 belonging to the first group G1 is used as a turn assist lamp in the same manner as the second group G2, the side of the optics can be exposed.

[0101] In the vehicle lamp 200 of the present invention described above, even when one of the multiple lamp modules 210, 220, 230, 240 forms a beam pattern different from the other, the optical axis of the optical part of each of the multiple lamp modules 210, 220, 230, 240 can be set to be parallel to each other. Therefore, the optical axis of the optical part will not change with the beam pattern, thereby forming an overall unified appearance. This reduces the sense of heterogeneity felt when the optical axes of the optical parts are arranged differently and enhances the aesthetics.

[0102] Those skilled in the art will understand that this invention can be implemented in other specific forms without altering its technical concept or essential features. Therefore, the embodiments described above should be understood as exemplary in all respects, not limiting. The scope of this invention is not limited by the detailed description provided, but by the claims. All modifications or variations derived from the meaning and scope of the claims and their equivalents should be interpreted as included within the scope of this invention.
