[0022] In the drawings, the symbol "F" represents "front", "B" represents "rear", "U" represents "up", "D" represents "down", "L" represents "left", and "R" represents "right". Also, in the drawings, since they are schematic diagrams, the main components are illustrated, the illustration of components other than the main components is omitted, and a part of the hatching is omitted. Further, FIG. 5 is illustrated in grayscale.

[0023] (Description of the configuration of the embodiment) Hereinafter, the configurations of the vehicle lamp unit devices 10L and 10R (hereinafter referred to as "lamp unit devices 10L and 10R") according to this embodiment, the vehicle lamp devices 100L and 100R (hereinafter referred to as "headlamp devices 100L and 100R") according to this embodiment, and the vehicle lamp control device 100 (hereinafter referred to as "lamp control device 100") according to this embodiment will be described.

[0024] (Description of the lamp control device 100) As shown in FIGS. 1 and 2, the lamp control device 100 includes a control device 200, a left headlamp device 100L, and a right headlamp device 100R.

[0025] As shown in FIG. 1, the lamp control device 100 is installed in the vehicle V. The design surface at the front of this vehicle V has an inclined (slant) shape that gradually retreats from the front side to the rear side of the vehicle V from the inside to the outside of the vehicle V on both the left and right sides.

[0026] (Description of the control device 200) As shown in FIG. 2, the control device 200 is installed in the vehicle V. The control device 200 includes detection units 201 and 202, a detection control unit 203, and a lighting on / off control unit 204.

[0027] In this example, the detection units 201 and 202 are composed of an imaging device (camera) 201 arranged at the center of the upper edge of the front windshield of the vehicle V and a millimeter-wave radar 202 arranged at the center of the front grille of the vehicle V.

[0028] The imaging device 201 captures images including oncoming vehicle V1 and preceding vehicle V2 with respect to the host vehicle V (the same reference numeral "V" as that of the vehicle is used). The millimeter-wave radar 202 measures the distances to the oncoming vehicle V1 and the preceding vehicle V2 with respect to the host vehicle V. The detection units 201 and 202 output detection signals to the detection control unit 203 via an interface.

[0029] The detection control unit 203 is an ECU for detection control, and includes an arithmetic control electronic device such as an MPU or a CPU, and a storage electronic device such as a RAM or a ROM. By executing a predetermined program stored in the storage electronic device by the arithmetic control electronic device, the detection control unit 203 calculates the positions and distances of the oncoming vehicle V1 and the preceding vehicle V2 based on the detection signals from the detection units 201 and 202, and outputs an arithmetic signal to the lighting control unit 204 via an interface.

[0030] The lighting control unit 204 is an ECU for lighting control, and includes an arithmetic control electronic device such as an MPU or a CPU, and a storage electronic device such as a RAM or a ROM. By executing a predetermined program stored in the storage electronic device by the arithmetic control electronic device, the lighting control unit 204 controls the lighting, extinguishing, increasing, and decreasing of the plurality of first light-emitting elements LED1 to LED10 and the second light-emitting element LED described below based on the arithmetic signal from the detection control unit 203.

[0031] (Description of the headlamp devices 100L and 100R) As shown in FIG. 1, the left headlamp device 100L is installed on the left side of the front part of the vehicle V, and the right headlamp device 100R is installed on the right side of the front part of the vehicle V.

[0032] As shown in FIG. 2, the headlamp devices 100L and 100R on both the left and right sides each include a lamp housing 101, a lamp lens 102, an inner panel (not shown), and a left lamp unit device 10L or a right lamp unit device 10R.

[0033] The lamp housing 101 is composed of an optically opaque resin member. The lamp lens 102 is composed of an optically transmissive resin member. The lamp lens 102 is an outer lens or an outer cover. The planar shape of the surface of the lamp lens 102 (the surface opposite to the surface on the lamp chamber 103 side described later) is, as shown in FIG. 1, along the design surface of the vehicle V, and gradually recedes from the front side to the rear side of the vehicle V as going from the inside to the outside of the vehicle V, forming an inclined (slant) shape.

[0034] The lamp housing 101 and the lamp lens 102 form a lamp chamber 103. Inside the lamp chamber 103, an inner panel, a left lamp unit device 10L or a right lamp unit device 10R is arranged.

[0035] The inner panel is composed of an optically opaque resin member. The inner panel is arranged so as to surround the periphery of the emission surface 12 of the first lens 10 and the emission surface 22 of the second lens 20 described later. Note that FIG. 3 is a front view showing the emission surface 12 of the first lens 10 and the emission surface 22 of the second lens 20 surrounded by an inner panel (not shown).

[0036] (Explanation of the lamp unit devices 10L and 10R on both the left and right sides) Hereinafter, the lamp unit devices 10L and 10R on both the left and right sides will be described with reference to FIGS. 2 to 8. Note that FIGS. 3 to 8 illustrate the right lamp unit device 10R. The left lamp unit device 10L has substantially the same configuration as the right lamp unit device 10R, and has a configuration with the left and right reversed. For this reason, the illustration of the left lamp unit device 10L similar to FIGS. 3 to 8 is omitted. Also, the expressions "on both the left and right sides", "left side", and "right side" will be omitted as appropriate.

[0037] The lamp unit devices 10L and 10R on both the left and right sides each include a first lamp unit 1L, 1R, a second lamp unit 2L, 2R, a heat sink 3 as the same mounting member, a fan unit 4, and a frame member 5.

[0038] In the right lamp unit device 10R, the outside of the vehicle V is the right side of the vehicle V, and the inside of the vehicle V is the left side of the vehicle V. In the left lamp unit device 10L, the outside of the vehicle V is the left side of the vehicle V, and the inside of the vehicle V is the right side of the vehicle V.

[0039] The first lamp units 1L and 1R and the second lamp units 2L and 2R are arranged in the left-right direction of the vehicle V. The first lamp units 1L and 1R are arranged inside the vehicle V. The second lamp units 2L and 2R are arranged outside and rearward of the vehicle V with respect to the first lamp units 1L and 1R.

[0040] (Description of the first lamp units 1L and 1R) As shown in FIGS. 2 to 5, the first lamp units 1L and 1R include a plurality of, in this example, 10 first light emitting elements LED1, LED2, LED3, LED4, LED5, LED6, LED7, LED8, LED9, LED10 (hereinafter referred to as "LED1 to LED10"), and light (not shown) from the 10 first light emitting elements LED1 to LED10, and a first lens 10 that irradiates the front of the vehicle V as first light distribution patterns P1L and P1R (see FIGS. 9(A) and (B)). The first lamp units 1L and 1R are lens direct type lamp units that directly cause the light from the first light emitting elements LED1 to LED10 to enter the first lens 10 and emit it from the first lens 10 as the first light distribution patterns P1L and P1R.

[0041] By superimposing and synthesizing the left and right first light distribution patterns P1L and P1R respectively irradiated from the first lamp units 1L and 1R on both the left and right sides, the overall first light distribution pattern P1 (see FIG. 11) is formed. In this example, the overall first light distribution pattern P1 is a wide high beam light distribution pattern that irradiates a wide range from the vicinity of the front side to the far side of the vehicle V and irradiates with high luminous intensity.

[0042] The first lamp units 1L and 1R are light distribution variable type lamp units, specifically, so-called ADB (Adaptive Driving Beam) type lamp units (vehicle lamps). When there are no preceding vehicles such as oncoming vehicle V1 or preceding vehicle V2, the first lamp units 1L and 1R form a first light distribution pattern P1, and when there are preceding vehicles, they are controlled to change to a light distribution pattern that makes the area where the preceding vehicles are present darker than the surrounding areas.

[0043] That is, the first lamp units 1L and 1R control the lighting, extinguishing, brightness increase, and decrease of the ten first light emitting elements LED1 to LED10 by the control device 200, so that the dark areas D1 (see FIG. 12) and D2 (see FIG. 13) in the first light distribution pattern P1 change.

[0044] (Description of the first light emitting elements LED1 to LED10) In this example, the ten first light emitting elements LED1 to LED10 are an LED array, and as shown in FIGS. 3 and 4, they are arranged in ten columns horizontally on one surface (front surface) of the first substrate 61. The light emitting surfaces of the first light emitting elements LED1 to LED10 are rectangular.

[0045] Note that the number of the first light emitting elements LED1 to LED10 is not limited to ten in this example. They may be arranged vertically, or may be arranged in a vertical and horizontal matrix. Furthermore, the first light emitting elements LED1 to LED10 may be semiconductor light emitting elements other than an LED array.

[0046] (Description of the first lens 10) As shown in FIGS. 2 to 5, the first lens 10 is a projection lens and is composed of an aspherical lens. The front view shape of the first lens 1 is a horizontally long rectangular shape. That is, the first lens 1 is obtained by largely cutting off the upper and lower sides of the first lens 1 having a circular front view shape, and slightly cutting off the inner side (left side) part of the vehicle V.

[0047] The first lens 1 controls the light from the first light-emitting elements LED1 to LED10 and irradiates the front of the vehicle V as the first light distribution patterns P1L and P1R. As shown in FIG. 4, the first lens 1 has an incident surface 11 and an exit surface 12. Here, the front view shape of the first lens 1 is the front view shape of the exit surface 12.

[0048] A part of the first lens 1, which is the outer (right) portion 13 of the vehicle V, and a part of the second lens 20 described later, which is the inner (left) portion 26 of the vehicle V, overlap by a dimension T in the longitudinal direction of the vehicle V as shown in FIG. 4.

[0049] The incident surface 11 is an aspherical surface, and in this example, it is an aspherical surface close to a plane. The light from the 10 first light-emitting elements LED1 to LED10 is respectively controlled as incident light (not shown) and made to enter the first lens 1.

[0050] The exit surface 12 is an aspherical surface, and in this example, it is an aspherical surface close to a spherical surface. The incident light from the 10 first light-emitting elements LED1 to LED10 is respectively controlled as exit light (not shown) and made to exit to the outside, that is, the front of the vehicle V.

[0051] In this way, the incident surface 11 and the exit surface 12 of the first lens 1 are designed and formed based on the light distribution of the 10 divided first light distribution patterns P1L1 to P1L10 and P1R1 to P1R10 described later.

[0052] The thickness of the first lens 1 is the thickest at the central portion, and gradually becomes thinner from the central portion toward the peripheral portion. Also, the radius of curvature of the incident surface 11 is larger than the radius of curvature of the exit surface 12. That is, the first lens 1 of the first lamp units 1L and 1R, which are ADB type lamp units, needs to irradiate the front of the vehicle V with the light from the 10 first light-emitting elements LED1 to LED10, entering from the incident surface 11 and exiting from the exit surface 12. For this reason, the radius of curvature of the incident surface 11 is large and the radius of curvature of the exit surface 12 is small.

[0053] The first lens 1 controls the projected images of the light emitting surfaces of the ten first light emitting elements LED1 to LED10, respectively, and irradiates the front of the vehicle V with ten divided first light distribution patterns P1L1, P1L2, P1L3, P1L4, P1L5, P1L6, P1L7, P1L8, P1L9, P1L10 (hereinafter referred to as "P1L1 to P1L10"), P1R1, P1R2, P1R3, P1R4, P1R5, P1R6, P1R7, P1R8, P1R9, P1R10 (hereinafter referred to as "P1R1 to P1R10") as shown in FIG. 9.

[0054] By superimposing and synthesizing the ten divided first light distribution patterns P1L1 to P1L10 and P1R1 to P1R10 on both the left and right sides respectively, the first light distribution patterns P1L and P1R on both the left and right sides are formed. Then, by superimposing and synthesizing the first light distribution patterns P1L and P1R on both the left and right sides respectively, the overall first light distribution pattern P1 is formed.

[0055] The lighting, extinguishing, increasing, and decreasing of the ten divided first light distribution patterns P1L1 to P1L10 and P1R1 to P1R10 on both the left and right sides are controlled based on the lighting, extinguishing, increasing, and decreasing of the ten first light emitting elements LED1 to LED10 controlled by the control device 200. As a result, the first lamp units 1L and 1R have high resolution in the first light distribution patterns P1L and P1R.

[0056] (Description of the second lamp units 2L and 2R) As shown in FIGS. 2 to 8, in this example, the second lamp units 2L and 2R include a second lens 20 that irradiates the front of the vehicle V with one second light emitting element LED and the light L1 from the one second light emitting element LED as second light distribution patterns P2L and P2R (see FIGS. 10(A) and (B)). The second lamp units 2L and 2R are lens direct type lamp units that directly incident the light L1 from the second light emitting element LED on the second lens 20 and emit it from the second lens 20 as the second light distribution patterns P2L and P2R.

[0057] The second light distribution patterns P2L and P2R on the left and right sides, respectively irradiated from the second lamp units 2L and 2R on the left and right sides, are superimposed and combined on the central portion of the first light distribution pattern P1 as shown in FIG. 11. Thereby, the shortage of the light quantity in the central portion of the first light distribution pattern P1 can be compensated. In this example, the second light distribution patterns P2L and P2R are spot high beam light distribution patterns that irradiate a range narrower than the range of the first light distribution pattern P1 with high luminosity.

[0058] Note that the second light distribution patterns P2L and P2R do not have to be entirely superimposed and combined on the central portion of the first light distribution pattern P1. That is, at least a part of the second light distribution patterns P2L and P2R may be superimposed and combined on the first light distribution pattern P1.

[0059] When there are no front vehicles such as oncoming vehicle V1 or preceding vehicle V2, the second lamp units 2L and 2R irradiate the second light distribution patterns P2L and P2R on the central portion of the first light distribution pattern P1, and when there are front vehicles, control is performed to stop the irradiation of the second light distribution patterns P2L and P2R.

[0060] That is, the second lamp units 2L and 2R irradiate or stop irradiating the second light distribution patterns P2L and P2R on the central portion of the first light distribution pattern P1 by controlling the lighting and extinguishing of the second light emitting elements LED by the control device 200.

[0061] (Description of the second light emitting element LED) As shown in FIGS. 2 to 4, in this example, the second light emitting element LED is an LED and is disposed on one surface (front surface) of the second substrate 62. The light emitting surface of the second light emitting element LED has a horizontally long rectangular shape.

[0062] Note that the number of the second light emitting elements LED is not limited to one in this example, and may be a plurality. In the case of a plurality, they may be arranged horizontally, vertically, or in a vertical and horizontal matrix. Further, the second light emitting element LED may be a semiconductor light emitting element other than an LED.

[0063] (Description of the Second Lens 20) As shown in FIGS. 2 to 8, the second lens 20 is a projection lens and is configured based on a pseudo-cylindrical lens 20B. Hereinafter, the pseudo-cylindrical lens 20B will be described with reference to FIG. 8.

[0064] The cylindrical lens 20A shown in FIG. 8(A) is a general cylindrical lens 20A. The general cylindrical lens 20A has an incident surface 21A and an exit surface 22A formed by extending along a linear cylindrical axis ZA.

[0065] In this example, the incident surface 21A and the exit surface 22A are convexly curved with respect to the cylindrical axis ZA. The radius of curvature of the incident surface 21A is larger than the curvature of the exit surface 22A. The radius of curvature of the incident surface 21A and the radius of curvature of the exit surface 22A are the same along the linear cylindrical axis ZA. Also, the thickness of the general cylindrical lens 20A is the same along the linear cylindrical axis ZA.

[0066] The cylindrical lens 20B shown in FIG. 8(B) is a pseudo-cylindrical lens 20B formed by curving the cylindrical axis ZA of the general cylindrical lens 20A in the left-right direction of the vehicle V. The incident surface 21B and the exit surface 22B of this pseudo-cylindrical lens 20B are curved in the left-right direction of the vehicle V along the cylindrical axis ZB. That is, the exit surface 22B recedes from the front side to the rear side of the vehicle V as it goes from the inside to the outside of the vehicle V along the slant of the design surface of the vehicle V.

[0067] The radius of curvature of the incident surface 21B is larger than the curvature of the exit surface 22B. The radius of curvature of the incident surface 21B and the radius of curvature of the exit surface 22B are the same along the curved-curve cylindrical axis ZB. Also, the thickness of the pseudo-cylindrical lens 20B is the same along the curved-curve cylindrical axis ZB.

[0068] The second lens 20 shown in FIG. 8(C) is formed by forming the incident surface 21B and the exit surface 22B of the pseudo-cylindrical lens 20B on the designed incident surface 21 and exit surface 22 based on the light distribution of the second light distribution patterns P2L and P2R.

[0069] That is, the exit surface 22 of the second lens 20 is formed to be the same as the exit surface 22B of the pseudo-cylindrical lens 20B.

[0070] As a result, as shown in FIG. 7, the radius of curvature of the exit surface 22 is the same along the curved cylindrical axis ZC. Also, as shown in FIG. 1 or FIG. 6, the planar view shape or the cross-sectional shape (horizontal cross-sectional shape) of the exit surface 22 recedes from the front side to the rear side of the vehicle V along the slant of the design surface of the vehicle V from the inside to the outside of the vehicle V.

[0071] On the other hand, the incident surface 21 of the second lens 20 is designed and formed based on the exit surface 22 so that the light distribution of the second light distribution patterns P2L and P2R can be obtained.

[0072] As a result, as shown in FIG. 7, the radius of curvature of the incident surface 21 is larger than that of the exit surface 22, and the central portion is the largest, gradually decreasing from the central portion to the peripheral portion.

[0073] Thereby, as shown in FIG. 6, the thickness of the second lens 20 is the thickest at the central portion and gradually becomes thinner from the central portion to the peripheral portion.

[0074] In this way, the second lens 20 is configured based on the pseudo-cylindrical lens 20B. As a result, as shown in FIGS. 6 and 7, the incident surface 21 controls and makes the light L1 from the second light-emitting element LED enter the second lens 2 as incident light L2. The exit surface 22 controls and emits the incident light L2 from the second light-emitting element LED as exit light L3 to the outside, that is, in front of the vehicle V, that is, spreads it in the left-right direction and narrows it in the up-down direction.

[0075] As a result, the incident surface 21 and the exit surface 22 of the second lens 20 irradiate the front of the vehicle V with second light distribution patterns P2L and P2R that widen the projected image of the light emitting surface of the second light emitting element LED in the left-right direction and narrow it in the up-down direction, as shown in FIG. 10.

[0076] As shown in FIGS. 3 to 5, the second lens 20 has a lens portion 23, a holding portion 24, and a fixing portion 25.

[0077] The lens portion 23 is configured based on a pseudo-cylindrical lens 20B and has an incident surface 21 and an exit surface 22.

[0078] The holding portion 24 has a frame shape. The front view shape of the holding portion 24 is a horizontally long rectangular shape that is the same as the front view shape of the first lens 1. The outer (right side) portion of the holding portion 24 of the vehicle V and the inner (left side) portion of the lens portion 23 of the vehicle V are integrally provided. The holding portion 24 holds the upper and lower edge portions of the first lens 10 and the inner (left side) edge portion of the vehicle V. That is, the holding portion 24 has a retainer function for holding the first lens 10.

[0079] The fixing portion 25 has a tongue piece shape that is integrally provided at the four corners of the rear side portion of the holding portion 24. The fixing portion 25 is fixed to the heat sink 3 by screws 30, thereby fixing the first lens 10 via the holding portion 24 and directly fixing the second lens 20 to the heat sink 3.

[0080] And a part of the lens portion 23 of the second lens 20, which is the inner (left side) portion 26 of the vehicle V, and a part of the first lens 1, which is the outer (right side) portion 13 of the vehicle V, overlap by a dimension T in the front-rear direction of the vehicle V, as shown in FIG. 4.

[0081] (Description of the heat sink 3) The heat sink 3 is composed of a member with high thermal conductivity, in this example, a member made of aluminum die-casting. As shown in FIGS. 4 and 5, the heat sink 3 is composed of a first mounting plate portion 31 and a first fin portion 310, and a second mounting plate portion 32 and a second fin portion 320. The first mounting plate portion 31 and the first fin portion 310, and the second mounting plate portion 32 and the second fin portion 320 are composed of an integral structure.

[0082] The mounting surface on the front surface of the first mounting plate portion 31 and the mounting surface on the front surface of the second mounting plate portion 32 are each parallel or substantially parallel to the vertical plane. As a result, the mounting surfaces of the first mounting plate portion 31 and the second mounting plate portion 32 are parallel or substantially parallel to the vertical direction and the horizontal direction. The mounting surface of the second mounting plate portion 32 is arranged with a step on the rear side of the vehicle V with respect to the mounting surface of the first mounting plate portion 31.

[0083] The first light-emitting elements LED1 to LED10 are mounted on the mounting surface of the first mounting plate portion 31 via the first substrate 61. The second light-emitting element LED is mounted on the mounting surface of the second mounting plate portion 32 via the second substrate 62.

[0084] As a result, the second light-emitting element LED is arranged with a step on the rear side of the vehicle V with respect to the first light-emitting elements LED1 to LED10. Also, the first light-emitting elements LED1 to LED10 and the second light-emitting element LED are each mounted on the heat sink 3, which is the same mounting member.

[0085] Further, the directions of the light-emitting surfaces of the first light-emitting elements LED1 to LED10 and the direction of the light-emitting surface of the second light-emitting element LED can be made the same direction, that is, forward.

[0086] The first fin portion 310 and the second fin portion 320 are integrally provided on the rear surfaces of the first mounting plate portion 31 and the second mounting plate portion 32, respectively, parallel or substantially parallel to the vertical plane. As a result, the first fin portion 310 and the second fin portion 320 are parallel or substantially parallel to the vertical direction. Note that the first fin portion 310 and the second fin portion 320 may be parallel or substantially parallel to the horizontal direction.

[0087] As a result, the directions of the first fin portion 310 and the second fin portion 320 are perpendicular or substantially perpendicular to the rear surfaces of the first mounting plate portion 31 and the second mounting plate portion 32, that is, the first substrate 61 of the first light-emitting elements LED1 to LED10 and the second substrate 62 of the second light-emitting element LED.

[0088] Also, the directions of the first fin portion 310 and the second fin portion 320 can be made the same direction, that is, backward.

[0089] (Description of the fan unit 4) As shown in FIGS. 4 and 5, the fan unit 4 is attached to the rear surface of the first fin portion 310 of the heat sink 3. Note that the rear surface of the first fin portion 310 of the heat sink 3 is located slightly forward with respect to the rear surface of the second fin portion 320. As a result, the rear surface of the fan unit 4 is located slightly rearward with respect to the rear surface of the second fin portion 320 of the heat sink 3.

[0090] The fan unit 4 cools the heat sink 3 from the heat generated in the first light-emitting elements LED1 to LED10 and the second light-emitting element LED by forcibly and directly blowing air onto the heat sink 3.

[0091] (Description of the frame member 5) As shown in FIGS. 4 and 5, the frame member 5 is composed of a fixed flange 50, a first frame 51, and a second frame 52. The fixed flange 50, the first frame 51, and the second frame 52 are composed of an integral structure.

[0092] The first frame 51 has a horizontally long rectangular cylindrical shape. The second frame 52 has a horizontally long rectangular cylindrical shape. The planar shape of the front opening edge of the second frame 52 is the same as the planar shape or cross-sectional shape (horizontal cross-sectional shape) of the light-emitting surface 22 of the second lens 2, and it recedes from the front side to the rear side of the vehicle V along the slant of the vehicle V as it goes from the inside to the outside of the vehicle V.

[0093] The outside (right side) of the vehicle V of the first frame 51 and the inside (left side) of the vehicle V of the second frame 52 are integrally provided. The fixing flange 50 is integrally provided at the rear opening edge of the first frame 51. The fixing flange 50 is fixed to the first mounting plate portion 31 of the heat sink 3 via the fixing portion 25 of the second lens 20 by the screw 30.

[0094] As a result, the first frame 51 is disposed between the incident surface 11 of the first lens 10 and the first mounting plate portion 31 of the heat sink 3, covering the incident surface 11 of the first lens 10 and the first light-emitting elements LED1 to LED10. Thereby, the first frame 51 can prevent light from leaking to the outside while the light from the first light-emitting elements LED1 to LED10 is incident on the incident surface 11 of the first lens 10.

[0095] On the other hand, the second frame 52 is disposed between the incident surface 21 of the second lens 20 and the second mounting plate portion 32 of the heat sink 3, covering the incident surface 21 of the second lens 20 and the second light-emitting element LED. Thereby, the second frame 52 can prevent light from leaking to the outside while the light L1 from the second light-emitting element LED is incident on the incident surface 21 of the second lens 20.

[0096] (Explanation of the operation of the embodiment) The lamp unit devices 10L and 10R according to this embodiment, the vehicle lamp devices 100L and 100R according to this embodiment, and the vehicle lamp control device 100 according to this embodiment are configured as described above, and the operation thereof will be described below.

[0097] (Explanation of the case where there are no preceding vehicles such as oncoming vehicle V1 or preceding vehicle V2) As shown in FIG. 11, when there are no preceding vehicles such as oncoming vehicle V1 or preceding vehicle V2, the detection units 201 and 202 of the control device 200 do not detect any preceding vehicles such as oncoming vehicle V1 or preceding vehicle V2. Therefore, the ten first light-emitting elements LED1 to LED10 of the first lamp units 1L and 1R of the headlamp devices 100L and 100R (lamp unit devices 10L and 10R) on both the left and right sides, and the second light-emitting elements LED of the second lamp units 2L and 2R are each lit.

[0098] Then, the light from the ten first light-emitting elements LED1 to LED10 of the first lamp units 1L and 1R on both the left and right sides respectively passes through the first lens 10 and is irradiated in front of the vehicle V as ten divided first light distribution patterns P1L1 to P1L10 and P1R1 to P1R10 on both the left and right sides as shown in FIG. 9.

[0099] These ten divided first light distribution patterns P1L1 to P1L10 and P1R1 to P1R10 on both the left and right sides are respectively formed as the first light distribution patterns P1L and P1R on both the left and right sides by overlapping and synthesizing. And these first light distribution patterns P1L and P1R on both the left and right sides are respectively formed as the overall first light distribution pattern P1 by overlapping and synthesizing.

[0100] On the other hand, the light L1 from the second light-emitting elements LED of the second lamp units 2L and 2R on both the left and right sides respectively passes through the second lens 20 and is irradiated in front of the vehicle V as the second light distribution patterns P2L and P2R on both the left and right sides as shown in FIG. 10.

[0101] These second light distribution patterns P2L and P2R on both the left and right sides are respectively superimposed and synthesized on the central portion of the first light distribution pattern P1 as shown in FIG. 11. Thereby, the insufficient light quantity in the central portion of the first light distribution pattern P1 is compensated.

[0102] (Explanation of the case where oncoming vehicle V1 is present) As shown in FIG. 12, when there is an oncoming vehicle V1, the detection units 201 and 202 of the control device 200 detect the oncoming vehicle V1. For this reason, the second light-emitting elements LED of the second lamp units 2L and 2R of the headlamp devices 100L and 100R (lamp unit devices 10L and 10R) on both the left and right sides are turned off or dimmed under the control of the control device 200. Then, as shown by the dashed lines in FIG. 12, the second light distribution patterns P2L and P2R on both the left and right sides disappear or their luminous intensity decreases.

[0103] At the same time, among the 10 first light-emitting elements LED1 to LED10 of the first lamp units 1L and 1R of the headlamp devices 100L and 100R (lamp unit devices 10L and 10R) on both the left and right sides, the first light-emitting elements that irradiate the area where the oncoming vehicle V1 is located, in this example, the first light-emitting elements LED8, LED9, and LED10 of the first lamp unit 1L on the left side, and the first light-emitting elements LED6, LED7, LED8, and LED9 of the first lamp unit 1R on the right side are turned off or dimmed under the control of the control device 200.

[0104] Then, among the 10 divided first light distribution patterns P1L1 to P1L10 and P1R1 to P1R10 on both the left and right sides, the first light-emitting elements LED8, LED9, and LED10 of the first lamp unit 1L on the left side that are turned off, and the first light-emitting elements LED6, LED7, LED8, and LED9 of the first lamp unit 1R on the right side, the corresponding left-side divided first light distribution patterns P1L8, P1L9, and P1L10, and the right-side divided first light distribution patterns P1L6, P1L7, P1L8, and P1L9 disappear or their luminous intensity decreases as shown by the dashed lines in FIG. 12. As a result, as shown in FIG. 12, in the first light distribution pattern P1, a dark area D1 is formed.

[0105] The divided first light distribution patterns P1L8, P1L9, P1L10 that have disappeared or dimmed, and the region D1 of the dark part formed by P1L6, P1L7, P1L8, P1L9 are the regions where the oncoming vehicle V1 is located. As a result, the region where the oncoming vehicle V1 is located, that is, the region D1 of the dark part, is darker than the regions around the region D1 of the dark part. Thereby, no glare light is given to the oncoming vehicle V1.

[0106] (Explanation when there is a preceding vehicle V2) As shown in FIG. 13, when there is a preceding vehicle V2, the detection units 201 and 202 of the control device 200 detect the preceding vehicle V2. For this reason, the second light emitting elements LED of the second lamp units 2L and 2R of the left and right headlamp devices 100L and 100R (lamp unit devices 10L and 10R) are turned off or dimmed under the control of the control device 200. Then, as shown by the broken lines in FIG. 13, the second light distribution patterns P2L and P2R on the left and right sides disappear or the light intensity decreases.

[0107] At the same time, among the 10 first light emitting elements LED1 to LED10 of the first lamp units 1L and 1R of the left and right headlamp devices 100L and 100R (lamp unit devices 10L and 10R), the first light emitting elements that irradiate the region where the preceding vehicle V2 is located. In this example, the first light emitting elements LED5, LED6, LED7, LED8 of the first lamp unit 1L on the left side and the first light emitting elements LED3, LED4, LED5, LED6 of the first lamp unit 1R on the right side are turned off or dimmed under the control of the control device 200.

[0108] Then, among the ten divided first light distribution patterns P1L1 to P1L10 and P1R1 to P1R10 on both the left and right sides, the first light emitting elements LED5, LED6, LED7, LED8 of the extinguished left first lamp unit 1L and the first light emitting elements LED3, LED4, LED5, LED6 of the right first lamp unit 1R respectively correspond to the left divided first light distribution patterns P1L5, P1L6, P1L7, P1L8 and the right divided first light distribution patterns P1L3, P1L4, P1L5, P1L6. As shown by the dashed lines in Fig. 13, they disappear or their light intensity decreases. As a result, as shown in Fig. 13, in the first light distribution pattern P1, a dark area D2 is formed.

[0109] The dark area D2 formed by the extinguished or dimmed divided first light distribution patterns P1L5, P1L6, P1L7, P1L8 and P1L3, P1L4, P1L5, P1L6 is the area where the preceding vehicle V2 is located. As a result, the area where the preceding vehicle V2 is located, that is, the dark area D2, is darker than the area around the dark area D2. Thereby, no dazzling light is given to the preceding vehicle V2.

[0110] (Explanation of cooling) The heat generated in the first light emitting elements LED1 to LED10 and the second light emitting element LED is released to the outside through the first substrate 61, the second substrate 62, and the heat sink 3 which is the same mounting member. Also, the heat sink 3 is cooled by forced air cooling by the fan unit 4.

[0111] (Explanation of the effects of the embodiment) The lamp unit devices 10L and 10R according to this embodiment, the vehicle lamp devices 100L and 100R according to this embodiment, and the vehicle lamp control device 100 according to this embodiment (hereinafter referred to as "lamp systems 10L, 10R, 100L, 100R, 100") are configured and operate as described above, and the effects thereof will be described below.

[0112] The lamp systems 10L, 10R, 100L, 100R, 100 include a first lamp unit 1L, 1R and a second lamp unit 2L, 2R. The first lamp units 1L, 1R include ten first light-emitting elements LED1 to LED10, and a first lens 10 that irradiates the light from the ten first light-emitting elements LED1 to LED10 as a first light distribution pattern P1 in front of the vehicle V. The second lamp units 2L, 2R include a second light-emitting element LED, and a second lens 20 that irradiates the light L1 from the second light-emitting element LED as second light distribution patterns P2L, P2R that are superimposed on the first light distribution pattern P1 in front of the vehicle.

[0113] Thereby, the lamp systems 10L, 10R, 100L, 100R, 100 can compensate for the insufficient light quantity of the first light distribution pattern P1 by superimposing and synthesizing the second light distribution patterns P2L, P2R on the first light distribution pattern P1, and can form a light distribution that irradiates a wide range with high brightness.

[0114] Also, in the lamp systems 10L, 10R, 100L, 100R, 100, the first lens 10 of the first lamp units 1L, 1R is composed of an aspherical lens, and by controlling the lighting and extinguishing of the ten first light-emitting elements LED1 to LED10 of the first lamp units 1L, 1R10, the regions D1, D2 of the dark parts in the first light distribution pattern P1 are controlled to change.

[0115] As a result, the lamp systems 10L, 10R, 100L, 100R, 100 form the first light distribution pattern P1 by the first lamp units 1L, 1R which are light distribution variable type lamp units (ADB type lamp units) when there are no front vehicles such as an oncoming vehicle V1 or a preceding vehicle V2, and when there is a front vehicle, the regions D1, D2 where the front vehicle exists can be changed to a light distribution pattern that is darker than the surrounding regions.

[0116] Furthermore, in the lamp systems 10L, 10R, 100L, 100R, 100, the second lens 20 of the second lamp unit 2L, 2R is composed of a pseudo-cylindrical lens 20B in which a cylindrical axis ZB in the left-right direction of the vehicle V is curved in the left-right direction of the vehicle V.

[0117] As a result, the lamp systems 10L, 10R, 100L, 100R, 100 can superimpose and synthesize the second light distribution patterns P2L, P2R that are widened in the left-right direction and narrowed in the up-down direction by the second lamp units 2L, 2R on the first light distribution pattern P1. Therefore, it is possible to compensate for the insufficient light quantity of the first light distribution pattern P1 and to form a light distribution that irradiates a wide range with high brightness.

[0118] In the lamp systems 10L, 10R, 100L, 100R, 100, the first lamp units 1L, 1R and the second lamp units 2L, 2R are arranged in the left-right direction of the vehicle V.

[0119] As a result, as shown in FIGS. 1 and 3, the lamp systems 10L, 10R, 100L, 100R, 100 can form a lens design that spreads in the left-right direction of the vehicle V by the first lens 10 of the first lamp units 1L, 1R and the second lens 20 of the second lamp units 2L, 2R.

[0120] Also, in the lamp systems 10L, 10R, 100L, 100R, 100, the second lamp units 2L, 2R are arranged outside the vehicle V with respect to the first lamp units 1L, 1R.

[0121] As a result, the lamp systems 10L, 10R, 100L, 100R, 100 can compensate for the insufficient light quantity outside the vehicle V of the first light distribution pattern P1 from the first lamp units 1L, 1R by the second light distribution patterns P2L, P2R from the second lamp units 2L, 2R, and can form a light distribution that irradiates a wide range with high brightness.

[0122] Furthermore, in the lamp systems 10L, 10R, 100L, 100R, 100, the planar shape or the horizontal cross-sectional shape of the exit surface 22 of the second lens 20 is inclined from the front side to the rear side of the vehicle V as going from the inner side to the outer side of the vehicle V along the design surface of the vehicle V.

[0123] As a result, even if the design surface at the front part of the vehicle V has a slant (slant) shape in which the left and right portions gradually recede from the front side to the rear side of the vehicle V as going from the inner side to the outer side of the vehicle V, the headlamp devices 100L, 100R can be equipped on the left and right sides at the front part of the vehicle V.

[0124] In the lamp systems 10L, 10R, 100L, 100R, 100, the second light-emitting element LED is arranged with a step with respect to the first light-emitting elements LED1 to LED10 on the rear side of the vehicle V.

[0125] As a result, even if the planar shape or the horizontal cross-sectional shape of the exit surface 22 of the second lens 20 arranged on the outer side of the vehicle V is inclined from the front side to the rear side of the vehicle V as going from the inner side to the outer side of the vehicle V along the design surface of the vehicle V, a sufficient distance can be ensured between the incident surface 21 of the second lens 20 and the second light-emitting element LED. Thereby, the second light distribution patterns P2L, P2R can be obtained based on a predetermined light distribution design.

[0126] In the lamp systems 10L, 10R, 100L, 100R, 100, the first light-emitting elements LED1 to LED10 and the second light-emitting element LED are respectively attached to a heat sink 3 which is the same attachment member.

[0127] As a result, the lamp systems 10L, 10R, 100L, 100R, 100 can position the relative positions of the first light-emitting elements LED1 to LED10 and the second light-emitting element LED with high precision. Therefore, the first light distribution pattern P1 and the second light distribution patterns P2L and P2R can be superposed and synthesized with high precision, and a light distribution pattern based on a predetermined light distribution design can be obtained.

[0128] In addition, the lamp systems 10L, 10R, 100L, 100R, 100 can align the directions of the light-emitting surfaces of the first light-emitting elements LED1 to LED10 and the light-emitting surface of the second light-emitting element LED in the same direction, that is, forward. Therefore, a light distribution pattern based on a predetermined light distribution design can be obtained.

[0129] Moreover, the lamp systems 10L, 10R, 100L, 100R, 100 can align the directions of the first fin portion 310 and the second fin portion 320 in the same direction, that is, backward. Therefore, a high cooling effect can be obtained.

[0130] In the lamp systems 10L, 10R, 100L, 100R, 100, the second lens 20 has a holding portion 24 that holds the first lens 10, and a fixing portion 25 that fixes the first lens 10 via the holding portion 24 and directly fixes the second lens 20 to the heat sink 3.

[0131] As a result, the lamp systems 10L, 10R, 100L, 100R, 100 can position the relative positions of the first lens 10 and the second lens 20 with high precision. Therefore, the first light distribution pattern P1 and the second light distribution patterns P2L and P2R can be superposed and synthesized with high precision, and a light distribution pattern based on a predetermined light distribution design can be obtained. Moreover, the number of parts can be reduced, and the manufacturing cost can be lowered.

[0132] In the lamp systems 10L, 10R, 100L, 100R, 100, a frame member 5 is disposed between the first lens 10 and the second lens 20 and the heat sink 3.

[0133] As a result, in the lamp systems 10L, 10R, 100L, 100R, 100, the frame member 5 can prevent light from the first light emitting elements LED1 to LED10 from leaking to the outside until it enters the incident surface 11 of the first lens 10. Similarly, light L1 from the second light emitting element LED can be prevented from leaking to the outside until it enters the incident surface 21 of the second lens 20.

[0134] In the lamp systems 10L, 10R, 100L, 100R, 100, an outer (right) portion 13 of the vehicle V, which is a part of the first lens 10 in the left-right direction of the vehicle V, and an inner (left) portion 26 of the lens portion 23 of the second lens 20, which is a part of the vehicle V, overlap in the front-rear direction of the vehicle V.

[0135] As a result, in the lamp systems 10L, 10R, 100L, 100R, 100, since the first lens 1 and the second lens 20 appear to be an integral structure, the appearance is improved.

[0136] (Description of examples other than the embodiment) In the above embodiment, an example in which the lamp unit devices 10L and 10R for irradiating a high beam light distribution pattern are arranged in the lamp chamber 103 has been described. However, in the present invention, in addition to the lamp unit devices 10L and 10R for irradiating a high beam light distribution pattern in the lamp chamber 103, for example, a lamp unit device for irradiating a low beam light distribution pattern, or a daytime running lamp device, etc. may be arranged.

[0137] Also, in the above embodiment, the first lamp units 1L and 1R and the second lamp units 2L and 2R are arranged in the left-right direction of the vehicle V. However, in the present invention, the first lamp units 1L and 1R and the second lamp units 2L and 2R may be arranged in the up-down direction or the diagonal direction of the vehicle V.

[0138] Furthermore, in the above-described embodiment, the second lamp units 2L and 2R are arranged outside the vehicle V with respect to the first lamp units 1L and 1R. However, in the present invention, the second lamp units 2L and 2R may be arranged inside the vehicle V with respect to the first lamp units 1L and 1R.

[0139] The present invention is not limited to the above-described embodiment.
