ASSOCIATED TECHNIQUE In patent document 1 or the like, there is known a vehicle lamp having a plurality of lamp units each emitting light forwardly. In this vehicle lamp, respective radiation regions are combined to form a light distribution pattern such as a low beam light distribution pattern. [Prior Art Documentation] [Patent Document] Patent Document 1: Japanese Patent Laid Open Publication No. 2003-317513. In such a vehicle lamp, precise alignment of the respective radiation regions is required. For example, in the case where the upper sides of the respective radiation regions deviate from each other in the vertical direction at the time of formation of a dipped beam light distribution pattern, a step appears in the lines cutting. As a result, the user feels discomfort.
    [0002] Accordingly, in order to precisely combine the respective radiation regions, a high dimensional accuracy is required for the components constituting the lamp, or high assembly precision is required.
    [0003] SUMMARY Embodiments of the invention provide a vehicle lamp which forms a light distribution pattern by combining the radiation regions of the plurality of lamp units and in which the vertical positions of the respective radiation regions can to be precisely aligned.
    [0004] A vehicle lamp according to an exemplary embodiment comprises: a plurality of lamp units each comprising a light source and a projection lens configured to emit forward the light emitted by the light source, wherein the units of the plurality of lamp units form a light distribution pattern by combining the radiation regions formed by each lamp unit, and at least one of the lamp units comprises a lens drive mechanism configured to tilt the projection lens in the vertical direction. According to the vehicle lamp of the present invention, the deviation of the radiation regions can be eliminated by the lens driving mechanism without improving the accuracy of the assembly. As a result, it is possible to form a light distribution pattern having a desired shape. The area of the projection lens may be less than or equal to 1000 mm 2, as seen in a front view. Generally, in a vehicle lamp that uses a plurality of small lamp units using a small lens, a deviation of the radiation regions is likely to occur. However, according to the present invention, the lens driving mechanism can be used to align a plurality of radiation regions so that the light distribution pattern formed by combining the multiple radiation regions has a desired shape. In addition, since the projection lens is light, it is possible to decrease the driving force of the lens driving mechanism. The projection lens can be made of resin. Since the projection lens is light, the power of the necessary lens driving mechanism can be reduced. The lens drive mechanism may include a detector configured to detect light emitted from the light source. According to the present invention, a failure of the light source can be detected by the detector. In addition, the detector can be provided in the vehicle lamp without requiring a separate structure to support the detector. The light source may comprise a semiconductor light emitting element and a luminophore layer having luminophores for emitting fluorescence by receiving light emitted from the semiconductor light emitting element, and the detector detects at least one intensity. among the intensity of the light emitted by the semiconductor light emitting element and the intensity of the fluorescence. When the phosphor layer is broken, the intensity of the light emitted by the semiconductor light emitting element increases or the fluorescence decreases. According to the present invention, it is possible to detect the rupture of the phosphor layer by means of the detector. According to the present invention, it is possible to provide a vehicle lamp which forms a light distribution pattern by combining the radiation regions of the plurality of lamp units and in which the vertical positions of the respective radiation regions can be precisely aligned.

    [0006] DETAILED DESCRIPTION A vehicle lamp according to an exemplary embodiment of the present invention will be described hereinafter in detail with reference to the drawings. A vehicle lamp according to the present embodiment is a lamp provided at the front of a vehicle.
    [0007] Figure 1 is a front view of a vehicle lamp 1 according to the present embodiment. Fig. 2 is a view through the line II-II of Fig. 1. In Fig. 1, the extension 6 (see Fig. 2) is omitted. The vehicle lamp 1 shown in Figure 1 is disposed on the front left side of a vehicle. The vehicle lamp 1 has a plurality (three in the example shown) of lamp units 10. The units of the plurality of lamp units 10 are arranged in the horizontal direction. The vehicle lamp 1 forms a dipped beam light distribution pattern by combining the radiation regions formed by three lamp units 10.
    [0008] FIG. 2 is a sectional view along the line II-II of FIG. 1. As shown in FIG. 2, the vehicle lamp 1 comprises a housing 2 having an opening portion at the front and an external cover 3 which closes the opening portion to form a lamp chamber S with the housing 2. The lamp unit 10 is provided inside the lamp chamber S. The lamp unit 10 is supported on a card 15. The support card 15 is fixed to the housing 2 by means of a sighting screw 5. The lamp unit 10 comprises a light source unit 11, a reflector 12, a mask part 13, a projection lens 14, support card 15, a light source holder 16 and a lens holder 17. The light source unit 11 includes a laser diode 11a and a phosphor layer 11b. The laser diode 11a is mounted on the upper surface of the light source holder 16. The phosphor layer 11b is mounted on the upper surface of the light source holder 16 so as to cover the upper surface of the laser diode 11a. The laser diode 11a emits a blue light. Part of the light emitted by the laser diode 11a emits yellow fluorescence as it passes through the phosphor layer 11b and its other portion passes through the phosphor layer 11b. In this way, the light source unit 11 emits a white light by mixing the blue light and the yellow light. The reflector 12 is attached to the upper surface of the light source holder 16 so as to cover the upper face of the light source unit 11. The reflector 12 has a spheroidal reflective surface. The reflector 12 reflects towards the projection lens 14 the light emitted by the light source unit 11. The projection lens 14 is a lens made of resin. The projection lens 14 is disposed on the front of the light source unit 11. The projection lens 14 is attached to the lens holder 17 which is attached to the front surface of the light source holder 16. The lens Projection lens 14 has a lens portion 14a and a flange portion 14b that emits light emitted by the light source unit 11 to the front. The lens portion 14a transmits the incident light forward and the flange portion 14b extends radially from the rear end of the lens portion 14a. The lens portion 14a has an area of less than or equal to 1000 mm 2, as viewed in a front view. The lens portion 14a preferably has an area of less than or equal to 500 mm 2, as viewed in a front view.
    [0009] The area of the lens portion 14a shown in FIG. 1 is 300 mm 2 as viewed from a front view. The upper front portion of the light source holder 16 has a recessed shape. An edge of the recessed form constitutes the mask portion 13. The mask portion 13 has a shape corresponding to a cutting line of a dipped beam light distribution pattern described later. The light emitted by the light source unit 11 is reflected by the reflector 12 and directed towards the projection lens 14. The light is then emitted towards the front of the lamp by the projection lens 14.
    [0010] The mask portion 13 blocks a portion of the light reflected by the reflector 12. In this manner, the cut lines of the low beam light distribution pattern are formed. (Lens drive mechanism) Fig. 3 is a view along the line of Fig. 1. As shown in Fig. 3, the lens unit 10 has a lens drive mechanism 20. The drive mechanism lens 20 comprises a plurality of adjusting screws 21 and a plurality of springs 22. The projection lens 14 is supported on the lens holder 17 by means of the adjusting screws 21 and the springs 22. The lens holder 17 is an annular metal plate. The flange portion 14b is provided with through-holes 24 traversed by the adjusting screws 21. The lens holder 17 and provided with screw holes 25 in which the adjusting screws 21 are screwed. The adjusting screws 21 pass through the through-holes 24 of the flange portion 14b and are screwed into the screw holes 25 of the lens holder 17. As shown in Fig. 2, extensions 6 are provided to cover the adjusting screws 24, as seen on a front view. As a result, the adjusting screws 21 are invisible from the outside. Cavities 26 are respectively provided in the surfaces of the flange portion 14b and the lens holder 17, which are opposed to each other. The cavities 26 are open so as to be turned towards each other. The springs 22 are arranged in a compressed state in the longitudinal direction between the cavities 26 of the flange portion 14b and the cavities 26 of the lens holder 17. The springs 22 exert a force on the projection lens 14 and the lens holder 17 in the direction of separation of the projection lens 14 and the lens holder 17. As shown in FIG. 1, the adjustment screws 21 are provided in the upper part, the lower part, the left part and the right part of the the flange portion 14b as viewed in a front view. As a result, the projection lens 14 can be inclined upwards when the adjustment screw 21 on the upper part is fixed and the screw 21 on the lower part is released, for example. In addition to tilting the projection lens 14 in the vertical direction, the lens driving mechanism 20 of the present embodiment can tilt the projection lens 14 in the lateral direction or adjust the distance between the projection lens 14 and the projection lens 14. the mask portion 13. The projection lens 14 may for example be inclined to the left when the adjusting screw 21 on the left side is fixed and the adjusting screw 21 on the right side is released. The projection lens 14 may for example be close to the mask portion 13 when all the adjusting screws 21 are fixed to the same extent. In this way, according to the vehicle lamp 1 of the present embodiment, it is possible to adjust the positions of the radiation regions which are formed by the lamp unit 10, since the lamp unit 10 comprises the mechanism of Lens Drive 20. (Optical Detector) As shown in Fig. 2 and Fig. 3, the lens driving mechanism 20 has an optical detector 18. The optical detector 18 is attached to the upper portion of the lens holder 17 The optical detector 18 can detect the intensity of the light emitted by the laser diode 11a. The optical detector 18 is connected to a control unit which controls the output of the laser diode 11a. The control unit may be provided inside the lamp chamber S or may be provided outside the lamp chamber S. The control unit may be a part of the vehicle lamp 1 or 20 a function of the control unit can be combined with an ECU (electrical control unit) mounted on a vehicle. An optical filter 19 is provided between the optical detector 18 and the laser diode 11a. In the example presented, the optical filter 19 is fixed on the underside of the optical detector 18 in the upper part of the lens holder 17. It is allowed to light having the same wavelength as the light emitted by the laser diode 11a to be transmitted through the optical filter 19 and the light having the other wavelength is blocked by the optical filter 19. As a result, the light having the same wavelength as the light emitted by the laser diode 11a reaches the optical detector 18. In a normal lighting state, the light having a constant intensity impacts the optical detector 18. The optical detector 18 can detect the breaking of the phosphor layer 11b. When the phosphor layer 11b is broken, the light emitted by the laser diode 11a is emitted without being attenuated by the phosphor layer 11b. As a result, the optical detector 18 receives high intensity light, relative to the case where the phosphor layer 11b is normal. As a result, the control unit decreases the power of the laser diode 11a or cuts the power of the laser diode 11a when the output value of the optical detector 18 exceeds a critical value. According to the present embodiment, the optical detector 18 is provided in the lens holder 17 forming part of the lens driving mechanism 20. Accordingly, it is not necessary to separately provide a structure to support the optical detector 18 .
    [0011] In the embodiment described above, an example has been described in which the optical detector 18 detects the intensity of the light having the same wavelength as the light emitted by the laser diode 11a. However, the optical detector 18 can detect light having the same wavelength as the fluorescence emitted by the phosphors.
    [0012] In this case, the intensity of the light received by the optical detector 18 increases when the phosphor layer 11b is broken. (Setting the radiation region) A method of adjusting the positions of the radiation regions using the lens driving mechanism 20 described above will then be described. Figs. 4A and 4B are views showing the radiation regions that are formed by each lamp unit of the vehicle lamp 1. Fig. 4A shows an example in which a low beam light distribution pattern is formed by radiation regions formed by three lamp units 10. In the present embodiment, the radiation regions formed by each lamp unit 10 are spaced from each other in the lateral direction. In this way, it is possible to radiate a wide range in the lateral direction.
    [0013] In a state where the vehicle lamp 1 is temporarily assembled, the positions in the vertical direction of the radiation regions may be spaced from each other, as in FIG. 4A. The lens driving mechanism 20 can be used even in this case to move the radiation regions so that the cutting lines of each radiation region are arranged in a straight line.
    [0014] For example, in the present embodiment, a first lamp unit 10 forms a radiation region L1, a second lamp unit 10 forms a radiation region L2, and a third lamp unit 10 forms a radiation region L3. When the radiation region L1 is formed in a position of suitable height as shown, the screwing value of the adjusting screw 21 of the second lamp unit 10 is adjusted so that the radiation region L2 is moved downwards. . In addition, the screwing value of the adjusting screw 21 of the third lamp unit 10 is set so that the radiation region L3 is moved upwards. In this way, the positions in the vertical direction of the cutting lines of the radiation regions L1 to L3 are aligned, so that it is possible to form a light distribution pattern which does not communicate discomfort to the driver. In this way, according to the vehicle lamp 1 of the present embodiment, the deviation of the radiation regions can be eliminated by the lens drive mechanism 20 without improving the accuracy of the assembly or the accuracy of the components of the invention. the projection lens 14 and the light source unit 11 or the like. As a result, it is possible to form a light distribution pattern having a desired shape. In addition, it is not necessary to move the entire vehicle lamp 10 to move the radiation regions. The radiation regions can be displaced simply by changing the posture of the projection lens 14. That is, the lens driving mechanism 20 can secure the driving force needed to move the projection lens. 14 and the rigidity necessary to maintain the posture of the projection lens 14. Accordingly, the lens driving mechanism 20 can be configured with a small size, in relation to the case where the entire vehicle lamp 10 is moved to move the radiation regions. As a result, the overall dimensions of the vehicle lamp 1 are less likely to increase. Further, in the vehicle lamp 1 of the present embodiment, the area of the projection lens 14 is less than or equal to 1000 mm 2, as seen in a front view. Generally, in a vehicle lamp in which is mounted a plurality of small lamp units including a small lens, the deviation of the radiation regions formed by each of the lamp units is likely to occur. However, depending on the vehicle lamp 1 of the present embodiment, the lens driving mechanism 20 may be used to align the multiple radiation regions into a desired shape. In addition, since the projection lens 14 is light, it is possible to decrease the driving force of the lens driving mechanism 20.
    [0015] In addition, in the vehicle lamp 1 of the present embodiment, the projection lens 14 is made of resin. The projection lens 14 is light with respect to a lens made of glass. As a result, the force required to control the projection lens 14 is low, so that the lens driving mechanism 20 can be configured with a small size. In the embodiment described above, an example has been described wherein each of the three lamp units 10 forms a radiation region having the same shape. However, each of the three lamp units 10 can form a radiation region having a shape different from the others. Fig. 4B shows an example in which each of three lamp units 10 forms a radiation region having a shape different from the others and a light distribution pattern is formed by three radiation regions. In the example shown, the first lamp unit 10 forms a first radiation region L constituting a dipped beam light distribution pattern, the second lamp unit 10 forms a second radiation region H constituting a distribution pattern of high beam light and the third lamp unit 10 forms a third radiation region A. The third radiation region forms an auxiliary light distribution pattern which is optimum for illuminating the road surface close to its own vehicle. The vehicle lamp 1 provides a light distribution pattern having high visibility by combining the first to the third radiation region L to A.
    [0016] In this example, in a state where the vehicle lamp 1 is temporarily assembled, the vertical positions of the central position CL of the first radiation region L, the central position CH of the second radiation region H and the central position CA of the third radiation region A can be separated from each other. The lens driving mechanism 20 can be used even in this case to form the first to the third radiation region L to A in optimal positions. In addition, the positional deviation in the lateral direction can also be adjusted when the lens driving mechanism 20 shown in Fig. 3 is used.
    [0017] The lens drive mechanism for tilting the projection lens in the vertical direction is not limited to the configuration described above. Figs. 5A and 5B are views showing a portion of a vehicle lamp 1A according to a first modified example of the present invention. Fig. 5A is a partial front view of the vehicle lamp 1A and Fig. 5B is a partial side view of the vehicle lamp 1A. As shown in FIGS. 5A and 5B, a lens driving mechanism 20A includes a rotating shaft portion 27, an upper adjusting screw 21 and a lower adjusting screw 21. The rotating shaft portion 27 is provided in the flange portion 14b of the projection lens 14 and extends in the horizontal direction. The adjustment of the upper and lower adjustment screws 21 causes the projection lens 14 to rotate around the rotating shaft portion 27, so that the projection lens 14 can be inclined in the vertical direction.
    [0018] Alternatively, the lens driving mechanism may be configured as shown in Figs. 6A and 6B. Figs. 6A and 6B are views showing a portion of a vehicle lamp 1B according to a second modified example of the present invention. Fig. 6A is a partial front view of the vehicle lamp 1B and Fig. 6B is a partial side view of the vehicle lamp 1B. A lens driving mechanism 20B shown in Figs. 6A and 6B includes the rotating shaft portion 27 and a stepping motor 29. The rotating shaft portion 27 is provided in the flange portion 14b of the lens. projection 14 and extends in the horizontal direction. The stepper motor 29 is connected to the rotating shaft portion 27 through a gear 28. When the stepper motor 29 rotates the rotating shaft portion 27, the projection lens 14 rotates around the rotating shaft portion 27. of the rotating shaft portion 27, so that the projection lens 14 can be inclined in the vertical direction. In this case, the lens driving mechanism 20B is controlled by a control unit provided in a lamp or a vehicle, so that the inclination in the vertical direction of the projection lens 14 can be adjusted. In the embodiment described above, a lens portion has been described, having a circular shape, as seen in a front view. However, the projection lens may have a rectangular shape or a polygonal shape, as seen in a front view. In the embodiment described above, an example has been described in which a laser diode is used as a semiconductor light emitting element. However, the present invention is not limited thereto. For example, an LED element or an EL element can be used.
    [0019] The number of units of the plurality of lamp units is not limited to three. The vehicle lamp may include any number (two or more) of lamp units. In addition, the direction of the arrangement of the plurality of lamp units is not limited to the horizontal direction. The units of the plurality of lamp units may be arranged in the vertical direction or may be arranged in matrix form in rows and columns. In addition, in the embodiment described above, an example has been described wherein the positions of the radiation regions are adjusted after temporarily assembling the vehicle lamp. The present invention is not limited thereto. The control of the alignment of the positions of the radiation regions can be executed at the start of the engine or at the ignition of the vehicle lamp, etc. In addition, the lens driving mechanism can be used to move the radiation regions during illumination, thereby changing the light distribution pattern. In addition, all units of the plurality of lamp units may not include the lens drive mechanism. At least one of the plurality of lamp units may include the lens drive mechanism. 35
