Description

[Technical field]

[0001] The present disclosure relates to a vehicle lamp. [Background technology]

[0002] Conventionally, a vehicle lamp having two light sources, a semiconductor-type light source and a separate semiconductor-type light source, on a substrate is known. A part of the light from the light-emitting portion of the semiconductor-type light source reflected by the first reflecting surface passes through an opening and is cut off, and the remaining reflected light is reflected by the second reflecting surface and passes through an optical lens to be irradiated to the outside in a predetermined basic light distribution pattern. The light from the light-emitting portion of the separate semiconductor-type light source is directly incident on the optical lens, passes through the optical lens, and is irradiated to the outside in a predetermined auxiliary light distribution pattern (for example, see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2007-324002 A Summary of the Invention [Problem to be solved by the invention]

[0004] In a conventional vehicle lamp, a separate semiconductor-type light source is disposed at a position away from the semiconductor-type light source toward the upper side, and light from the light-emitting portion of the separate semiconductor-type light source is directly incident on the lower half region of the optical lens (see FIG. 6 of Patent Document 1). Therefore, the separate semiconductor-type light source and the lower half region of the optical lens are disposed at the same height position overlapping in the vertical direction. As a result, the semiconductor-type light source and the first reflector disposed below the separate semiconductor-type light source are disposed at a position protruding further downward from the lower end of the optical lens. For this reason, the board on the separate semiconductor-type light source side of the boards on which the two semiconductor-type light sources are provided and the optical lens overlap in the front-rear direction, and the vertical dimension of the lamp is the length obtained by adding the vertical dimension of the board to the vertical dimension of the optical lens, which does not meet the demand for compact lamps and leaves room for improvement.

[0005] The present disclosure has been made in light of the above-mentioned problems, and has an object to provide a vehicle lamp that meets the demand for compactness in a lamp that can obtain different light distribution patterns by switching light sources. [Means for solving the problem]

[0006] In order to achieve the above object, the vehicle lamp of the present disclosure includes a light source, a reflector that reflects light incident from the light source, and an illumination lens that illuminates the reflected light incident from the reflector to the outside. The light source includes a first light source and a second light source provided on a substrate. The illumination lens is formed by dividing it into a plurality of parts, and includes a second lens area in which the first light source is arranged at the rear, and a first lens area in which the second light source is arranged at the rear. The reflector includes a first light source reflector that reflects the light incident from the first light source toward the first lens area, and a second light source reflector that reflects the light incident from the second light source toward the second lens area. The first light source is a light source for high beam, and the second light source is a light source for low beam. The first light source reflector is a first high reflector having a first reflecting surface that reflects light from the light source for high beam, and a second high reflector having a second reflecting surface that reflects reflected light from the first reflecting surface. The second light source reflector is a first low reflector having a first reflecting surface that reflects light from the light source for low beam, and a second low reflector having a second reflecting surface that reflects reflected light from the first reflecting surface. The irradiation lens is divided into two lens areas, upper and lower, by a lens area boundary. The first lens area is a lower lens area below the lens area boundary, and is a high lens area into which reflected light from the second high reflector is incident. The second lens area is an upper lens area above the lens area boundary, and is a low lens area into which reflected light from the second low reflector is incident. The first high reflector, the second high reflector, the first low reflector, and the second low reflector are arranged at positions where the optical path from the high beam light source and the optical path from the low beam light source do not block each other's optical paths. The first high reflector and the second low reflector are arranged in an upper space above a lens area boundary portion that extends from the lens area boundary toward the substrate in the opposing space between the irradiation lens and the substrate. The first low reflector and the second high reflector are arranged in a lower space below the lens area boundary in the opposing space. The first high reflector, the second high reflector, the first low reflector, and the second low reflector are arranged to overlap each other in the up-down direction. Effect of the Invention

[0007] Therefore, in a lighting fixture that can obtain different light distribution patterns by switching the light source, it is possible to meet the demand for compact lighting fixtures. Moreover, while satisfying the condition that the optical path of the reflected light in the selected light distribution pattern is not blocked, each reflector can be arranged compactly in the opposing space between the irradiation lens and the substrate.

FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a vehicle lamp according to an embodiment of the present disclosure will be described with reference to a first embodiment shown in the drawings. EXAMPLES

[0010] The vehicle lamp in the first embodiment is used as a lamp unit in a vehicle such as an automobile, and is applied to, for example, a headlamp or a fog lamp. The lamp unit is disposed on both the left and right sides of the front of the vehicle, and is provided in a lamp chamber formed by covering the open front end of the lamp housing with an outer lens. In the following description, in the lamp unit, the direction in which light is emitted that is the traveling direction when the vehicle travels straight ahead is defined as the front-rear direction (Z in the drawings), the direction that represents the up and down when mounted on the vehicle is defined as the up-down direction (Y in the drawings), and the direction perpendicular to the front-rear direction and the up-down direction is defined as the width direction (X in the drawings).

[0011] First, the configuration of a lamp unit 10 (an example of a vehicle lamp) applied to a headlamp of an automobile will be described with reference to Figs. 1 and 2.

[0012] The lamp unit 10 includes a high beam light source 1 (first light source), a low beam light source 2 (second light source), a first high reflector 3 (first light source reflector), a second high reflector 4 (first light source reflector), a first low reflector 5 (second light source reflector), a second low reflector 6 (second light source reflector), and an irradiation lens 7. The lamp unit 10 has a unit configuration in which a high beam light distribution unit that obtains a HI beam light distribution pattern and a low beam light distribution unit that obtains a Lo beam light distribution pattern are integrated into one unit.

[0013] The high beam light source 1 is a high beam irradiation light source provided on the surface of the substrate 8. When the surface extending from the step surface 7b (lens area boundary) of the irradiation lens 7 toward the substrate 8 is called the lens area boundary 70, the high beam light source 1 is disposed at a position above the lens area boundary 70 as shown in FIG. 2. In the first embodiment, the lens area boundary 70 is described as a "surface" extending from the step surface 7b, but it is sufficient that a boundary is provided by a step or trim. Here, when the irradiation lens 7 has a condensing lens portion 73 and a diffusing lens portion 74, the high beam light source 1 may be provided at a position corresponding to each of the condensing side first high reflector 31 and the diffusing side first high reflector 32 described later (total of two), as shown in FIG. 1.

[0014] Here, the "lens area boundary" refers to the step surface 7b that divides the irradiation lens 7 into a first lens area (for example, the high lens area 71) and a second lens area (for example, the low lens area 72). The lens area boundary of the irradiation lens 7 in the first embodiment is the horizontal step surface 7b that passes through a position slightly above the center position of the irradiation lens 7, and is set to a surface where the vertical dimension of the high lens area 71 is longer than the vertical dimension of the low lens area 72. In other words, the area of ​​the high lens area 71 is set to be larger than the area of ​​the low lens area 72. This is to meet the demand for increasing the area of ​​the high lens area 71. Furthermore, this is to meet the demand for increasing the solid angle in order to increase the amount of light on the high beam side more than on the low beam side.

[0015] The low beam light source 2 is a low beam irradiation light source provided on the surface of the substrate 8. The low beam light source 2 is disposed below the lens area boundary 70 as shown in FIG. 2. Here, when the irradiation lens 7 has a condensing lens portion 73 and a diffusing lens portion 74, the low beam light source 2 may be provided at positions corresponding to each of the condensing side first low reflectors 51, 52, and 53 described below (a total of three light sources), as shown in FIG. 1. Furthermore, the low beam light source 2 may be provided at positions corresponding to each of the diffusing side first low reflectors 54 and 55 (a total of two light sources).

[0016] Here, self-luminous semiconductor light sources are used as the high beam light source 1 and the low beam light source 2, and in the first embodiment, LED light sources (LED is an abbreviation for "Light Emitting Diode") are used. The high beam light source 1 and the low beam light source 2 are provided with a heat sink (not shown) for dissipating heat generated by the light source to the outside, and the heat sink is made of a metal material (e.g., aluminum die casting) or a resin material having high thermal conductivity. Note that if the substrate 8 has a function for dissipating heat generated by the light source to the outside, a configuration without a heat sink may be used.

[0017] A light source drive circuit that switches the light distribution pattern (HI beam light distribution pattern, Lo beam light distribution pattern) by switching the light emitting point is connected to the high beam light source 1 and the low beam light source 2. Note that there are several methods for switching the light emitting point, including a manual switching method in which the driver manually operates the light emitting point, an automatic switching method in which the light emitting point is automatically switched by detecting a preceding vehicle or an oncoming vehicle, and a switching method that combines manual and automatic switching.

[0018] The first high reflector 3 is attached to a substrate 8 or the like, and has a first reflecting surface 3a that reflects light from the high beam light source 1. The first reflecting surface 3a is a reflecting surface such as a free-form surface based on an ellipse or an ellipse (e.g., a NUBRS curved surface) that reflects light incident from the high beam light source 1 in the forward / backward direction (Z-axis direction) and changes the light path direction downward (downward direction of the Y axis) toward the second high reflector 4. The first high reflector 3 is disposed in front of the high beam light source 1. Here, when the irradiation lens 7 has a condensing lens section 73 and a diffusing lens section 74, as the first high reflector 3, one condensing side first high reflector 31 may be provided in the condensing lens section 73, and one diffusing side first high reflector 32 may be provided in the diffusing lens section 74, as shown in FIG. 1. The light-collection-side first high reflector 31 and the light-diffusion-side first high reflector 32 may be disposed at the same height position above the lens area boundary extension portion 70.

[0019] The second high reflector 4 is attached to a substrate 8 or the like, and has a second reflecting surface 4a that reflects the reflected light from the first reflecting surface 3a of the first high reflector 3. The second reflecting surface 4a is a reflecting surface such as a flat surface or a curved surface that is close to a flat surface, which receives the reflected light from the first high reflector 3 and changes the light path direction in the front-rear direction (Z-axis direction) toward the high lens area 71. The second high reflector 4 is disposed in a position near the high lens focal point F1 behind the high lens area 71. Here, when the projection lens 7 has a condenser lens section 73 and a diffusing lens section 74, the second high reflector 4 is formed of a rectangular flat plate material or the like, and may be provided integrally in the vehicle width direction (X-axis direction) across the condenser lens section 73 and the diffusing lens section 74 as shown in FIG. 1. The second high reflector 4 may be disposed slightly below the lens area boundary section 70, at a position where the entire length of the reflector in the vertical direction overlaps with the projection lens 7 in the vertical direction.

[0020] The first low reflector 5 is attached to the substrate 8 or the like and has a first reflecting surface 5a that reflects light from the low beam light source 2. The first reflecting surface 5a is a reflecting surface such as a free-form surface based on an ellipse or an ellipse (for example, a NUBRS curved surface) that reflects light incident from the low beam light source 2 in the forward and backward directions (Z-axis direction) and changes the light path direction in the upward direction (upward direction of the Y axis) toward the second low reflector 6. The first low reflector 5 is disposed in front of the low beam light source 2. Here, when the irradiation lens 7 has a condensing lens section 73 and a diffusing lens section 74, as shown in FIG. 1, three condensing side first low reflectors 51, 52, and 53 may be provided in the condensing lens section 73 as the first low reflector 5. And, two diffusing side first low reflectors 54 and 55 may be provided in the diffusing lens section 74. The light-collection-side first low reflectors 51, 52, and 53 and the diffusion-side first low reflectors 54 and 55 may be disposed at the same height position below the lens area boundary portion 70.

[0021] The second low reflector 6 is attached to the substrate 8 or a heat sink not shown, and has a second reflecting surface 6a that reflects the reflected light from the first reflecting surface 5a. The second reflecting surface 6a is a reflecting surface such as a curved surface based on a revolution ellipsoid that receives the reflected light from the first low reflector 5 and changes the light path direction in the front-back direction (Z-axis direction) toward the low lens area 72. The second low reflector 6 is disposed at a front lower position of the first high reflector 3. Here, when the irradiation lens 7 has a condensing lens part 73 and a diffusing lens part 74, the second low reflector 6 is composed of a rectangular curved plate material, and may be integrally provided in the vehicle width direction (X-axis direction) across the condensing lens part 73 and the diffusing lens part 74 as shown in FIG. 1. In addition, in the center of the reflector on the condensing lens side, a cutoff step end surface 6b is formed as shown in FIG. 1 in order to create a cutoff line that becomes the boundary between light and dark when forming a Lo beam condensing area in the Lo beam light distribution pattern. The second low reflector 6 may be located above the lens area boundary portion 70.

[0022] Here, the arrangement of the reflectors 3, 4, 5, 6 will be described with reference to FIG. 2. The first high reflector 3, the second high reflector 4, the first low reflector 5, and the second low reflector 6 are arranged in a facing space 90 between the rear surface of the projection lens 7 and the front surface of the substrate 8. Here, the reflectors 3, 4, 5, 6 are arranged at positions where the optical paths from the high beam light source 1 and the low beam light source 2 do not block each other in the HI beam light distribution pattern and the Lo beam light distribution pattern (see FIG. 3 and FIG. 4). The first high reflector 3, the second high reflector 4, the first low reflector 5, and the second low reflector 6 may be individually attached to the substrate 8 or the like. Also, the reflectors 3, 4, 5, 6 may be integrally configured as a reflector unit set on a support plate, and the support plate may be attached to the substrate 8 or the like.

[0023] The first high reflector 3 is disposed immediately before the high beam light source 1, and the second low reflector 6 is disposed at a front lower position of the first high reflector 3. That is, the first high reflector 3 and the second low reflector 6 are disposed at a position in the space above the lens area boundary 70 in the facing space 90 (= a position in the space behind the low lens area 72) where the first high reflector 3 and the second low reflector 6 partially overlap each other in the vertical direction. The first low reflector 5 is disposed immediately before the low beam light source 2, and the second high reflector 4 is disposed at an upper position of the first low reflector 5. That is, the first low reflector 5 and the second high reflector 4 are disposed at a position in the space below the lens area boundary 70 in the facing space 90 (= a position in the space behind the high lens area 71) where the first low reflector 5 and the second high reflector 4 overlap each other in the vertical direction.

[0024] The illumination lens 7 is an optical lens that is attached to a substrate 8 or the like via a holder (not shown) and is disposed in front of the reflectors 3, 4, 5, and 6. The illumination lens 7 is made of a transparent resin (e.g., an acrylic resin or a polycarbonate resin) and is formed by resin molding that can accommodate a variety of lens shapes. The illumination lens 7 divides the rear surface of the lens into an upper area and a lower area by a step surface 7b that is the lens area boundary, with the lower area of ​​the illumination lens 7 being a high lens area 71 and the upper area of ​​the illumination lens 7 being a low lens area 72.

[0025] The high lens area 71 refracts the reflected light incident from the second high reflector 4 and irradiates it to the outside, thereby forming a HI beam light distribution pattern. The low lens area 72 refracts the reflected light incident from the second low reflector 6 and irradiates it to the outside, thereby forming a Lo beam light distribution pattern.

[0026] The positional relationship between the high lens area 71 and the low lens area 72 and the high beam light source 1 and the low beam light source 2 will be described. The irradiation lens 7 is divided into two when it is divided into the high beam side and the low beam side without being divided by light collection and diffusion, and has the low lens area 72 with the high beam light source 1 arranged at the rear, and the high lens area 71 with the low beam light source 2 arranged at the rear. Therefore, the HI beam light distribution pattern set combining the high beam light source 1 and the high lens area 71 and the Lo beam light distribution pattern set combining the low beam light source 2 and the low lens area 72 are set in a cross arrangement that intersects in the vertical direction with the lens area boundary part 70 in between.

[0027] The illumination lens 7 has a lens surface 7a, which is the exit surface of the illumination light, formed of a curved surface with a continuous curvature. On the other hand, the lens back surface, which is the entrance surface of the reflected light, is divided into a first lens back surface 7c and a second lens back surface 7d with a step surface 7b as the lens area boundary, and the first lens back surface 7c and the second lens back surface 7d are set to have individual curvatures. Here, when the back surface of the illumination lens 7 has a step structure as in Example 1, the step surface 7b becomes the lens area boundary that divides the lens area of ​​the illumination lens 7. Note that, when both the front surface and the back surface of the illumination lens are smooth surfaces without steps, the position or region of the illumination lens where the lens curvature changes becomes the lens area boundary.

[0028] That is, the position where the light path of light parallel to the optical axis incident from the lens surface is focused after passing through the high lens area 71 becomes the high lens focus F1 (first lens focus). On the other hand, the position where the light path of light parallel to the optical axis incident from the lens surface is focused after passing through the low lens area 72 becomes the low lens focus F2 (second lens focus). The front-rear position of the high lens focus F1 and the front-rear position of the low lens focus F2 are set to be different in the front-rear direction. As a result, the sunlight incident on each lens of the high lens area 71 and the low lens area 72 is focused near each lens focus (high lens focus F1, low lens focus F2).

[0029] In the first embodiment, the lens curvature of the second lens back surface 7d is made larger than that of the first lens back surface 7c, so that the low lens focus F2 is located forward of the high lens focus F1 in the front-rear direction. The position of the high lens focus F1 is a position where the optical path of light parallel to the optical axis incident from the lens surface is focused after passing through the high lens area 71 (see FIG. 7). Specifically, the high lens focus F1 is set at the upper position of the reflecting surface 4a of the second high reflector 4 (see FIG. 3). On the other hand, the position of the low lens focus F2 is a position where the optical path of light parallel to the optical axis incident from the lens surface is focused after passing through the low lens area 72 (see FIG. 6). Specifically, the low lens focus F2 is set at a position approximately at the lower end of the second low reflector 6 and further forward from the surface of the substrate 8 than the position of the high lens focus F1 (see FIG. 4).

[0030] As shown in FIG. 1, the illumination lens 7 has a condensing lens section 73 and a diffusing lens section 74 integrally disposed adjacent to each other in the vehicle width direction. The condensing lens section 73 is formed in a lens shape that condenses the reflected light incident on the high lens area 71 and the low lens area 72, which are divided into upper and lower sections, and irradiates the light to the outside. The diffusing lens section 74 is formed in a lens shape that diffuses the reflected light incident on the high lens area 71 and the low lens area 72, which are divided into upper and lower sections, and irradiates the light to the outside. For each of the condensing lens section 73 and the diffusing lens section 74, the vertical area defined by the lens upper end surface 7e and the lens lower end surface 7f is divided into the high lens area 71 and the low lens area 72. Furthermore, each of the condensing lens section 73 and the diffusing lens section 74 includes a high beam light source 1 and a low beam light source 2. In addition, it is equipped with a first high reflector 3 having a first reflective surface 3a, a second high reflector 4 having a second reflective surface 4a, a first low reflector 5 having a first reflective surface 5a, and a second low reflector 6 having a second reflective surface 6a.

[0031] Next, the light distribution pattern forming action of the lamp unit 10 in the first embodiment will be described with reference to Fig. 3 to Fig. 5. In the light distribution pattern diagram in Fig. 5, V indicates a vertical line in the up-down direction passing through the center point O, and H indicates a horizontal line in the vehicle width direction passing through the center point O.

[0032] When the high beam light source 1 is turned on, a HI beam light distribution pattern is formed by light irradiated from the high lens area 71 to the outside. When forming a HI beam light distribution pattern during night driving, both the high beam light source 1 and the low beam light source 2 are turned on. Therefore, when forming a Low beam light distribution pattern while driving with a HI beam light distribution pattern, the turned on high beam light source 1 is turned off.

[0033] 3, the light emitted from the high beam light source 1 is reflected by the first reflecting surface 3a of the diffusion-side first high reflector 32, changes its optical path downward, and becomes reflected light toward the second high reflector 4. The reflected light from the first reflecting surface 3a is reflected by the second reflecting surface 4a of the second high reflector 4, changes its optical path toward the front of the vehicle, and enters the first lens back surface 7c of the high lens area 71 of the irradiation lens 7. The reflected light that enters the first lens back surface 7c is refracted according to the lens shape of the high lens area 71, and is irradiated to the outside from the lens front surface 7a. Therefore, when the high beam is turned on, a HI beam diffusion region 101 of the HI beam light distribution pattern is formed from the diffusion lens section 74 side.

[0034] When the high beam is turned on, an HI beam concentration region 100 of the HI beam light distribution pattern is formed from the side of the condenser lens portion 73. Note that, although an example of the high beam light distribution in which light is distributed separately into concentrated and diffused light has been shown, there are also cases in which the same light distribution pattern is formed without being divided into concentrated and diffused light.

[0035] For this reason, the condenser lens portion 73 of the irradiation lens 7 forms an HI beam collection region 100 with high illuminance and a horizontally elongated shape that is symmetrical in the up-down and left-right directions with respect to the center position O, as shown in Fig. 5. At the same time, the diffusing lens portion 74 of the irradiation lens 7 forms an HI beam diffusion region 101 with a horizontally elongated shape and lower illuminance than the HI beam collection region 100, so as to surround the outer periphery of the HI beam collection region 100, as shown in Fig. 5. As a result, when the high beam light source 1 is selected as the light-emitting location, an HI beam light distribution pattern (also called a "driving light distribution pattern") can be formed by combining the HI beam collection region 100 and the HI beam diffusion region 101, as shown in Fig. 5.

[0036] On the other hand, when the low beam light source 2 is turned on, a low beam light distribution pattern is formed by the light irradiated from the low lens area 72 to the outside.

[0037] 4, the light emitted from the low beam light source 2 is reflected by the first reflecting surface 5a of the light-collecting side first low reflector 52, changes its optical path upward, and becomes reflected light toward the second low reflector 6. The reflected light from the first reflecting surface 5a is reflected by the second reflecting surface 6a of the second low reflector 6, changes its optical path toward the front of the vehicle, and enters the second lens back surface 7d of the low lens area 72 of the irradiation lens 7. The reflected light that enters the second lens back surface 7d is refracted according to the lens shape of the low lens area 72, and is irradiated to the outside from the lens surface 7a. Therefore, by using the light-collecting side first low reflectors 51, 52, and 53 of the collecting lens portion 73, the Low beam collecting region 200 of the Low beam light distribution pattern is formed. At this time, since the cutoff step end face 6a is formed in the second low reflector 6, the Lo beam collection area 200 has a cutoff line which is the boundary between the dark area and the bright area, and light is not irradiated upward or is not irradiated upward.

[0038] When the low beam light source 2 is selected as the light emitting portion, the low beam light source 2 in the diffusion lens portion 74 is also turned on at the same time, so that the light emitted from the low beam light source 2 is reflected by the first reflecting surface 5a of the diffusion-side first low reflector 54. Therefore, by using the diffusion-side first low reflector 54 in the diffusion lens portion 74, a Low beam diffusion region 201 in the Low beam light distribution pattern is formed.

[0039] Therefore, as shown in Fig. 5, the condensing lens portion 73 of the irradiation lens 7 forms a Lo beam collection region 200 that is horizontally elongated and has an asymmetric cutoff line in the left-right direction below the center position O, and has a lower illuminance than the HI beam collection region 100. At the same time, as shown in Fig. 5, the diffusing lens portion 74 of the irradiation lens 7 forms a Lo beam diffusion region 201 that overlaps the lower side of the Lo beam collection region 200, is horizontally elongated and offset in the vehicle width direction, and has a lower illuminance than the Lo beam collection region 200. As a result, when the low beam light source 2 is selected as the light emitting location, a Lo beam light distribution pattern (also called a "passing light distribution pattern") can be formed by combining the Lo beam collection region 200 and the Lo beam diffusion region 201, as shown in Fig. 5.

[0040] Next, the characteristics and functions of the lighting unit 10 in the first embodiment will be described with reference to FIGS.

[0041] In the first embodiment, the illumination lens 7 is divided into a plurality of parts, and has a low lens area 72 behind which the high beam light source 1 is disposed, and a high lens area 71 behind which the low beam light source 2 is disposed. The reflector has a first high reflector 3 and a second high reflector 4 that reflect the light incident from the high beam light source 1 toward the high lens area 71, and a first low reflector 5 and a second low reflector 6 that reflect the light incident from the low beam light source 2 toward the low lens area 72.

[0042] In the background art of vehicle lighting, various sensors are being placed in the unit to add various functions. As vehicle lighting becomes more multifunctional, there is a demand for making the headlamp unit itself as compact as possible so that space for mounting sensors and the like can be secured.

[0043] In contrast, when the projection lens 7 is divided into lens areas 71 and 72 by the step surface 7b, which is the lens area boundary, for the light sources 1 and 2, a combination of light distribution patterns can be created by one corresponding light source and one corresponding lens area. For example, when a combination of two light distribution patterns is created, the high beam light source 1 is arranged behind the low lens area 72, and the low beam light source 2 is arranged behind the high lens area 71. In this case, the high lens area 71 and the low beam light source 2, and the low lens area 72 and the high beam light source 1 are arranged to face each other in the front-rear direction, respectively, and it is possible to compact the lamp unit 10 in the vertical direction. Therefore, when the high beam light source 1 and the low beam light source 2 are arranged on the same plane of the substrate 8 and a light distribution pattern is irradiated by one projection lens 7 (divided into areas), it is possible to provide a lamp unit 10 that is compact in the vertical direction and the front-rear direction by making it compact, including making it thinner in the front-rear direction.

[0044] In the first embodiment, the first light source is the high beam light source 1, the second light source is the low beam light source 2, and the irradiation lens 7 is divided into two parts, upper and lower, by a step surface 7b which is the lens area boundary, into an upper low lens area 72 and a lower high lens area 71. The low lens area 72 of the irradiation lens 7 is set so that the high beam light source 1 is disposed behind it, and the high lens area 71 of the irradiation lens 7 is set so that the low beam light source 2 is disposed behind it.

[0045] For example, in the first embodiment, when combination lines C and D of the cross arrangement are drawn as shown in Fig. 2, the high lens area 71 and the low beam light source 2, and the low lens area 72 and the high beam light source 1 are arranged to face each other in the front-rear direction. Therefore, the substrate 8 on which both light sources 1 and 2 are provided overlaps the irradiation lens 7 entirely in the front-rear direction, achieving compactness in the vertical direction. Note that in the first embodiment, Figs. 1 and 2 show an example in which the vertical dimension L0 of the irradiation lens is smaller than the vertical dimension L1 of the substrate, but the vertical dimension L0 of the irradiation lens may be equal to the vertical dimension L1 of the substrate, or the vertical dimension L0 of the irradiation lens may be larger than the vertical dimension L1 of the substrate.

[0046] Furthermore, the first light source reflector disposed between the irradiation lens 7 and the substrate 8 is the first high reflector 3 and the second high reflector 4, and the second light source reflector is the first low reflector 5 and the second low reflector 6. Therefore, by adopting a configuration in which light is incident on the irradiation lens 7 by being reflected twice, including in the upward and downward directions, the distance between the irradiation lens 7 and the substrate 8 can be narrowed, and the device can be made more compact in the front-to-back direction.

[0047] Furthermore, in the design of the light distribution patterns of high beam and low beam, if a common lens is used as in the prior art, the light distribution design is difficult. In contrast, the light distribution design is made easier by the fact that the irradiation lens 7 has a high lens area 71 and a low lens area 72 separately. In addition, since there is a separate lens area for high beam, the light amount of the HI beam light distribution pattern is also improved by making the high lens area 71 large. Therefore, in the lighting unit 10 in which different light distribution patterns can be obtained by switching between the high beam light source 1 and the low beam light source 2, it is possible to meet the demand for compactness in the vertical and front-rear directions of the lighting unit 10. In addition, the light distribution design of the HI beam light distribution pattern and the Low beam light distribution pattern is made easier, and the light amount of the HI beam light distribution pattern can be improved.

[0048] In the first embodiment, the first high reflector 3, the second high reflector 4, the first low reflector 5, and the second low reflector 6 are arranged in positions where the optical paths from the high beam light source 1 and the low beam light source 2 do not obstruct each other's optical paths.

[0049] That is, when an HI beam light distribution pattern in which light from the high beam light source 1 travels is selected, the first low reflector 5 and the second low reflector 6 do not block the optical path of the reflected light passing through the first high reflector 3 and the second high reflector 4, as shown by an arrow 91 in Fig. 3. When an Lo beam light distribution pattern in which light from the low beam light source 2 travels is selected, the first high reflector 3 and the second high reflector 4 do not block the optical path of the reflected light passing through the first low reflector 5 and the second low reflector 6, as shown by an arrow 92 in Fig. 4. For this reason, the reflectors 3, 4, 5, and 6 can be disposed between the irradiation lens 7 and the substrate 8 while ensuring the optical path of the reflected light in the HI beam light distribution pattern and the optical path of the reflected light in the Lo beam light distribution pattern.

[0050] In the first embodiment, the first high reflector 3 and the second low reflector 6 are disposed in an upper space above the lens area boundary 70 in the facing space 90. The first low reflector 5 and the second high reflector 4 are disposed in a lower space below the lens area boundary 70 in the facing space 90. The first high reflector 3, the second high reflector 4, the first low reflector 5, and the second low reflector 6 are disposed so as to overlap each other in the vertical direction.

[0051] In other words, by dividing the four reflectors 3, 4, 5, 6 into 2 (reflectors 3, 6):2 (reflectors 4, 5) with the lens area boundary 70 as the boundary, it is possible to form a more finely detailed light distribution compared to, for example, dividing into 1 (one of reflectors 3, 4, 5, 6):3 (the remaining three of reflectors 3, 4, 5, 6).

[0052] In addition, the four reflectors 3, 4, 5, and 6 are arranged so as to overlap each other in the vertical direction, thereby reducing the space required for arranging the reflectors. For example, as shown in Fig. 2, when the first low reflector 5, which has the largest shape, is used as a reference, the first high reflector 3 and the second high reflector 4 completely overlap in the vertical direction, and the second low reflector 6 partially overlaps in the vertical direction. This allows the reflectors 3, 4, 5, and 6 to be arranged compactly in the front-to-back direction of the opposing space 90 between the irradiation lens 7 and the substrate 8, while still satisfying the basic condition of a lamp equipped with a reflector, that is, not blocking the optical path of reflected light in a selected light distribution pattern.

[0053] In Example 1, the forward / backward position of the high lens focus F1 by the high lens area 71 is set to a position near the substrate 8, and the forward / backward position of the low lens focus F2 by the low lens area 72 is set to a position forward of the forward / backward position of the high lens focus F1.

[0054] That is, since the front-rear direction position of the high lens focus F1 is set in the vicinity of one board 8, the setting positions of the high beam light source 1 and the low beam light source 2 provided on one board 8 do not exceed the front-rear direction position of the high lens focus F1. Therefore, as shown in Fig. 2, the front-rear direction dimension L2 of the lamp unit 10 determined by the front surface position of the irradiation lens 7 and the back surface position of the board 8 can be shortened. In addition, since the front-rear direction position of the low lens focus F2 is set in a position forward of the front-rear direction position of the high lens focus F1, it becomes possible to arrange the reflectors 3, 4, 5, and 6 on the high beam side and the low beam side in the facing space 90 between the irradiation lens 7 and the board 8.

[0055] By setting the front-rear position of the low lens focus F2 to a position forward of the front-rear position of the high lens focus F1, the position of the high lens focus F1 and the position of the low lens focus F2 by the low lens area 72 are different positions in the front-rear direction. Therefore, the concentrated energy of the sun is dispersed to the position of the high lens focus F1 and the position of the low lens focus F2. This dispersion effect of the concentrated energy of the sun makes it possible to select materials with a lowered heat resistance temperature as the material of parts such as the reflectors 3, 4, 5, and 6 and the substrate 8. Therefore, the lamp unit 10 can be manufactured at low cost, and the front-rear dimension L2 of the lamp unit 10 can be shortened.

[0056] In the first embodiment, the high lens focus F1 of the high lens area 71 is disposed at a position (upper end side) corresponding to the second high reflector 4. The low lens focus F2 of the low lens area 72 is disposed at a position (lower end side) corresponding to the second low reflector 6.

[0057] That is, since the high lens focal point F1 is disposed at a position (upper end side) corresponding to the second high reflector 4, the second high reflector 4 is disposed at a position behind the high lens area 71. Since the low lens focal point F2 is disposed at a position (lower end side) corresponding to the second low reflector 6, the second low reflector 6 is disposed at a position behind the low lens area 72. Therefore, the reflected light from the second high reflector 4 effectively and accurately enters the high lens area 71 of the projection lens 7, and the reflected light from the second low reflector 6 effectively and accurately enters the low lens area 72 of the projection lens 7.

[0058] In the first embodiment, the first high reflector 3 is disposed behind the low lens area 72 together with the high beam light source 1, and the second high reflector 4 is disposed behind the high lens area 71. The first low reflector 5 is disposed behind the high lens area 71 together with the low beam light source 2, and the second low reflector 6 is disposed behind the low lens area 72.

[0059] That is, the low beam light source 2, the first low reflector 5, and the second high reflector 4 having the high lens focus F1 at its upper end are arranged in a concentrated manner behind the high lens area 71 of the irradiation lens 7. The high beam light source 1, the first high reflector 3, and the second low reflector 6 having the low lens focus F2 at its lower end are arranged in a concentrated manner behind the low lens area 72 of the irradiation lens 7 (see FIG. 2). Therefore, the high beam light source 1, the low beam light source 2, and the reflectors 3, 4, 5, and 6 are arranged in a compact concentrated manner in the space behind the high lens area 71 of the irradiation lens 7 and the space behind the low lens area 72 of the irradiation lens 7.

[0060] In the first embodiment, the illumination lens 7 has a condensing lens portion 73 that condenses the incident reflected light and irradiates it to the outside, and a diffusing lens portion 74 that diffuses the incident reflected light and irradiates it to the outside, which are adjacent to each other in the vehicle width direction. Each of the condensing lens portion 73 and the diffusing lens portion 74 is divided into a high lens area 71 and a low lens area 72.

[0061] That is, as shown in FIG. 5, the HI beam light collection region 100 is obtained by the high lens area 71 of the condenser lens section 73, and the HI beam diffusion region 101 is obtained by the high lens area 71 of the diffusion lens section 74. The Lo beam light collection region 200 is obtained by the low lens area 72 of the condenser lens section 73, and the Lo beam diffusion region 201 is obtained by the low lens area 72 of the diffusion lens section 74. The HI beam light distribution pattern is obtained by an appropriate illuminance distribution by the combination of the HI beam light collection region 100 and the HI beam diffusion region 101. The Lo beam light distribution pattern is obtained by an appropriate illuminance distribution by the combination of the Lo beam light collection region 200 and the Lo beam diffusion region 201. Therefore, by switching the light emitting points of the high beam light source 1 and the low beam light source 2, it is possible to obtain an HI beam light distribution pattern with an appropriate illuminance distribution and an Lo beam light distribution pattern with an appropriate illuminance distribution.

[0062] As described above, the lighting unit 10 of the first embodiment provides the following effects.

[0063] (1) A vehicle lamp (lamp unit 10) includes a light source, a reflector that reflects light incident from the light source, and an illumination lens 7 that irradiates the reflected light incident from the reflector to the outside. The light source includes a first light source (high beam light source 1) and a second light source (low beam light source 2) provided on a substrate 8. The illumination lens 7 is divided into a plurality of parts, and includes a second lens area (low lens area 72) behind which the first light source (high beam light source 1) is disposed, and a first lens area (high lens area 71) behind which the second light source (low beam light source 2) is disposed. The reflector has a first light source reflector (first high reflector 3, second high reflector 4) that reflects the light incident from the first light source (light source for high beam 1) toward the first lens area (high lens area 71), and a second light source reflector (first low reflector 5, second low reflector 6) that reflects the light incident from the second light source (light source for low beam 2) toward the second lens area (low lens area 72). Therefore, in the lighting unit 10 in which different light distribution patterns can be obtained by switching between the first light source (light source for high beam 1) and the second light source (light source for low beam 2), it is possible to meet the demand for compactness of the lighting unit 10.

[0064] (2) The first light source is the high beam light source 1, and the second light source is the low beam light source 2. The first light source reflector is the first high reflector 3 having a first reflecting surface 3a that reflects light from the high beam light source 1, and the second high reflector 4 having a second reflecting surface 4a that reflects the reflected light from the first reflecting surface 3a. The second light source reflector is the first low reflector 5 having a first reflecting surface 5a that reflects light from the low beam light source 2, and the second low reflector 6 having a second reflecting surface 6a that reflects the reflected light from the first reflecting surface 5a. The irradiation lens 7 is divided into two lens areas, upper and lower, by a lens area boundary (step surface 7b). The first lens area is the lower lens area below the lens area boundary (step surface 7b), and is the high lens area 71 into which the reflected light from the second high reflector 4 is incident. The second lens area is an upper lens area above the lens area boundary (step surface 7b), and is a low lens area 72 into which reflected light from the second low reflector 6 is incident. Therefore, in the lighting unit 10 in which a HI beam light distribution pattern and a Lo beam light distribution pattern can be obtained by switching between the high beam light source 1 and the low beam light source 2, it is possible to meet the demand for compact vertical dimensions of the unit.

[0065] (3) The first high reflector 3, the second high reflector 4, the first low reflector 5, and the second low reflector 6 are disposed at positions where the optical path from the high beam light source 1 and the optical path from the low beam light source 2 are not blocked by each other. Therefore, the reflectors 3, 4, 5, and 6 can be disposed between the irradiation lens 7 and the substrate 8 while ensuring the optical path of reflected light in the HI beam light distribution pattern and the optical path of reflected light in the Low beam light distribution pattern.

[0066] (4) The first high reflector 3 and the second low reflector 6 are disposed in an upper space above a lens area boundary portion 70 that extends from the lens area boundary (step surface 7b) toward the substrate 8 in the facing space 90 between the irradiation lens 7 and the substrate 8. The first low reflector 5 and the second high reflector 4 are disposed in a lower space below the lens area boundary portion 70 in the facing space 90. The first high reflector 3, the second high reflector 4, the first low reflector 5, and the second low reflector 6 are disposed so as to overlap each other in the up-down direction. For this reason, the reflectors 3, 4, 5, and 6 can be disposed compactly in the facing space 90 between the irradiation lens 7 and the substrate 8 while satisfying the condition that the optical path of the reflected light is not blocked in the selected light distribution pattern.

[0067] (5) The front-rear direction position of the first lens focus (high lens focus F1) of the first lens area (high lens area 71) is set to a position near the substrate 8. The front-rear direction position of the second lens focus (low lens focus F2) of the second lens area (low lens area 72) is set to a position forward of the front-rear direction position of the first lens focus. Therefore, there is no need to use a highly heat-resistant material for the components, the lamp unit 10 can be manufactured at low cost, and the front-rear direction dimension L2 of the lamp unit 10 can be shortened.

[0068] (6) The first lens focus (high lens focus F1) of the first lens area (high lens area 71) is disposed at a position corresponding to the second high reflector 4 of the first light source reflector. The second lens focus (low lens focus F2) of the second lens area (low lens area 72) is disposed at a position corresponding to the second low reflector 6 of the second light source reflector. For this reason, the reflected light from the second high reflector 4 can be effectively and accurately incident on the high lens area 71 of the projection lens 7, and the reflected light from the second low reflector 6 can be effectively and accurately incident on the low lens area 72 of the projection lens 7.

[0069] (7) The first high reflector 3 of the first light source reflector is disposed behind the second lens area (low lens area 72) together with the first light source (high beam light source 1), and the second high reflector 4 is disposed behind the first lens area (high lens area 71). The first low reflector 5 of the second light source reflector is disposed behind the first lens area (high lens area 71) together with the second light source (low beam light source 2), and the second low reflector 6 is disposed behind the second lens area (low lens area 72). For this reason, the high beam light source 1, the low beam light source 2, and the respective reflectors 3, 4, 5, and 6 can be disposed compactly and concentratedly in the space behind the high lens area 71 of the projection lens 7 and the space behind the low lens area 72 of the projection lens 7.

[0070] (8) The first light source (high beam light source 1) and the second light source (low beam light source 2) are provided on the same plane. Therefore, the front-rear dimension L2 of the lamp unit 10 can be made shorter than when the two light sources are provided on different planes.

[0071] (9) The illumination lens 7 has a condensing lens section 73 that condenses the incident reflected light and irradiates it to the outside, and a diffusing lens section 74 that diffuses the incident reflected light and irradiates it to the outside, which are located adjacent to each other in the vehicle width direction. Each of the condensing lens section 73 and the diffusing lens section 74 is divided into a high lens area 71 and a low lens area 72. Therefore, by switching the light emission points of the high beam light source 1 and the low beam light source 2, it is possible to obtain an HI beam light distribution pattern with an appropriate illuminance distribution in which a concentrated area and a diffused area are combined, and an Low beam light distribution pattern with an appropriate illuminance distribution in which a concentrated area and a diffused area are combined.

[0072] The vehicle lamp of the present disclosure has been described above based on Example 1, however, the specific configuration is not limited to this Example 1, and design changes and additions are permitted as long as they do not deviate from the gist of the invention according to each claim in the claims.

[0073] In the first embodiment, an example is shown in which the illumination lens 7 is divided into two areas by the lens area boundary 70 on the rear surface of the lens. However, the illumination lens may be divided into two areas by a lens dividing surface on the front surface of the lens, or may be divided into two areas by lens dividing surfaces on the front surface and the rear surface of the lens. Furthermore, the illumination lens may be divided into three or more areas.

[0074] In the first embodiment, an example was shown in which the lens area boundary is a horizontal surface that divides the projection lens 7 into a high lens area 71 and a low lens area 72. However, the lens area boundary of the projection lens is not limited to a horizontal surface, and may be a vertical surface, in which case the width dimension can be shortened. Furthermore, the projection lens may be divided by an inclined surface having an inclination angle from the horizontal or vertical surface.

[0075] In the first embodiment, the high beam light source 1 is shown as the first light source, and the low beam light source 2 is shown as the second light source. However, the first light source and the second light source are not limited to the high beam light source and the low beam light source used for generating a HI beam light distribution pattern and a Lo beam light distribution pattern, and may have at least two types of light sources according to different applications.

[0076] In the first embodiment, an example is shown in which the condenser lens portion 73 and the diffusing lens portion 74 are integrally provided at adjacent positions in the vehicle width direction as the illumination lens 7. However, the illumination lens is not limited to this, and may be provided as an example in which the condenser lens portion and the diffusing lens portion are provided separately at adjacent positions in the vehicle width direction. Furthermore, it may be provided as an example in which another lens portion is sandwiched between the condenser lens portion and the diffusing lens portion.

[0077] In the first embodiment, an example of a unit that switches between a high beam light distribution pattern and a low beam light distribution pattern has been shown as the lighting unit 10. The lighting unit is not limited to a unit that switches between a high beam light distribution pattern and a low beam light distribution pattern, and may be a unit that switches between various light distribution patterns other than a high beam and a low beam.
