(First embodiment)
FIG. 1 shows a front view of a vehicle according to a first embodiment of the present invention. A vehicle 5 according to the first embodiment of the present invention (hereinafter referred to as “vehicle 5”) includes a vehicle body 6 and a lamp 7 according to the first embodiment of the present invention (hereinafter referred to as “lamp 7”).

  As shown in FIGS. 4 and 5, the lamp 7 includes a housing 9 and an illumination device 10 (hereinafter, referred to as “illumination device 10”) according to the first embodiment of the present invention disposed inside the housing 9. Is provided. The lamp 7 is a headlamp for a motorcycle, for example, and is provided on the front side of the vehicle 5 so as to illuminate the front of the vehicle 5. The lamp 7 has, for example, a substantially disk shape.

  The housing 9 is, for example, a metal casing having a bottomed cylindrical shape, and has an opening 11 that emits light from the illumination device 10. As shown in FIG. 2, the opening 11 is covered with a cover 8. The cover 8 is made of, for example, a light-transmitting resin and transmits light from the lighting device 10. In addition, since the cover 8 is provided so as to close the opening 11 of the housing 9, it is possible to prevent moisture and dust from entering the inside of the housing 9. The cover 8 has an arbitrary configuration in the lamp 7.

As shown in FIG. 3, the housing 9 has a heat radiating portion 12 on the back side. By having the heat dissipating part 12, it is possible to easily dissipate heat generated during lighting of a light emitting element described later. The heat dissipating part 12 includes, for example, a plurality of heat dissipating fins 12a. As shown in FIG. 3, the radiation fins 12a are arranged in parallel in the left-right direction on the paper surface of FIG. The direction in which the radiating fins 12a are arranged is not particularly limited. However, by arranging the radiating fins 12a in a direction parallel to the vertical direction, the heat generated from the radiating fins 12a can be easily released upward. Can be improved.

  An insertion hole 13 for inserting a power supply line (not shown) for supplying power to the lighting device 10 is provided in the lower part on the back side of the housing 9. The insertion hole 13 is preferably sealed with packing or the like so that moisture or the like does not enter the lamp 7 in a state where the power supply line is inserted.

  As shown in FIGS. 4 to 6, in the illumination device 10, a first lens group 14 for traveling mode illumination and a second lens group 15 for passing mode illumination adjacent to the first lens group 14 are integrally formed. The lens assembly 16 and a plurality of light emitting elements 19 arranged to face the lenses 17 and 18 of the 16 lens assembly.

  The light emitting element 19 shown in FIG. 6 is, for example, a light emitting diode. Specifically, a SMD (SURFACE MOUNT DEVICE) type in which one or more LED chips are mounted on a package substrate (not shown) is mounted on the substrate 20. The light emitting elements 19 shown in FIG. 6 and subsequent figures are of the SMD type and are so-called LED packages. When a light emitting diode is used as the light emitting element 19, a COB (CHIP ON BOARD) type in which one or more LED chips are mounted on the substrate 20 may be used.

  The light emitting diode may emit white light using a blue LED chip and a wavelength conversion member such as a phosphor, or white light using blue, red, and green LED chips. May be emitted.

  The light emitting element 19 is disposed to face the lenses 17 and 18. Specifically, the light emitting element 19 is disposed at a position including the substantially central axis of each of the lenses 17 and 18, and the light emitted from the light emitting element 19 is collected and emitted by the lenses 17 and 18. .

  The first lens group 14 has a plurality of lenses 17. The lenses 17 have substantially the same structure, and are arranged so that their emission surfaces are adjacent to each other. As shown in FIGS. 4 and 5, the first lens group 14 includes, for example, a total of 16 lenses 17 of 2, 5, 6, and 3 arranged in a substantially parallel row from the top to the bottom. Has been.

  As shown in FIG. 6, the lens 17 is a condensing lens having a portion where the emission surface 17 a is flat. Specifically, the lens 17 has a substantially frustoconical shape whose outer diameter increases from the light emitting element 19 side toward the emission surface 17a, and has a concave portion 17b on the opposite side of the emission surface. The recess 17b has a convex bottom surface 17c on the light emitting element 19 side and a side surface 17d formed so as to surround the bottom surface 17b. Furthermore, a space between the opposite side of the bottom surface 17c of the side surface 17d and the emission surface 17a in the recess 17b is a parabolic surface 17e that swells outward.

  The light emitted from the light emitting element 19 enters the lens 17 from the bottom surface 17c or the side surface 17d of the recess 17b. Light incident from the bottom surface 17c is collected by the convex bottom surface 17c and emitted from the emission surface 17a. On the other hand, the light incident from the side surface 17d is reflected by the parabolic surface 17e, thereby being condensed and emitted from the emission surface 17a. Thereby, the light for driving mode illumination can be radiate | emitted from the output surface 17a of the lens 17. FIG.

  The second lens group 15 has a plurality of lenses 18. The lenses 18 have substantially the same structure, and are arranged so that the emission surfaces 18a are adjacent to each other. As shown in FIGS. 4 and 5, in the second lens group 15, a total of nine lenses 18, for example, two and seven from the upper side to the lower side are arranged in a substantially parallel row.

  As shown in FIG. 6, the lens 18 is a condensing lens whose exit surface 18a is a convex curved surface. Specifically, the lens 18 has a substantially semi-ellipsoidal shape in which the exit surface 18a is a convex curved surface and the entrance surface 18b is a flat surface.

  The light emitted from the light emitting element 19 enters the lens 18 from the incident surface 18b. The light incident from the incident surface 18b is condensed by the output surface 18a and emitted. Thereby, the light for passing mode illumination can be emitted from the emission surface 18 a of the lens 18. In addition, since the light of passing mode illumination needs to suppress the light which goes upward, it is preferable to design the shape of the exit surface 18a of the lens 18 so that the light emitted from the lens 18 is directed downward. For example, in a cross section parallel to the vertical direction including the optical axis of the light emitting element 19, the upward light is obtained by making the curvature of the upper side of the exit surface 18 a of the lens 18 larger than the curvature of the lower side of the exit surface 18 a of the lens 18. Can be suppressed. In addition, you may provide the interruption | blocking part which interrupts | blocks the light which goes upwards from the output surface 18a of the lens 18, the reflective part etc. which reflect. These are possible by evaporating or pasting a material on the upper side of the exit surface 18a of the lens or in the vicinity thereof.

  Since the first lens group 14 and the second lens group 15 are integrally formed in the lens assembly 16, the lens assembly 16 does not have to be individually fixed to the light emitting element 19. 16 can be fixed together, and it is possible to suppress the occurrence of a shift in the light distribution due to a shift between the lenses 17 and 18 due to an external impact or the like.

  The lens assembly 16 has an outer wall portion 21 on the substrate 20 side so as to surround the first lens group 14 and the second lens group. The lens assembly 16 is made of acrylic resin, for example. The lens assembly 16 is not limited to acrylic resin but may be made of polycarbonate resin. As shown in FIG. 6, it is preferable that the inner side of the front end portion 21a of the outer wall portion 21 is cut away. In this case, it is possible to easily align the substrate 20 and the lens assembly 16 by fitting the substrate 20 into the notch portion 21b of the distal end portion 21a.

  As shown in FIGS. 4 and 5, grooves 22 for inserting screws (not shown) for fixing the lens assembly 16 to the housing 9 are formed at four locations on the outer periphery of the lens assembly 16. ing. In this case, the lens assembly 16 can be simply fixed to the housing 9 by screwing. Furthermore, it is preferable that the periphery of the groove 22 in the lens assembly 16 is recessed toward the substrate 20 with respect to the exit surfaces 17a and 18a of the lenses 17 and 18. In this case, when a screw is inserted into the groove 22, the screw head (not shown) is hidden in the recess 23 around the groove 22, so that the light emitted from the emission surfaces 17 a and 18 a of the lenses 17 and 18 is obstructed. Can be difficult.

  Further, it is preferable that a protrusion 24 that protrudes toward the substrate 20 is provided in the vicinity of the center of the lens assembly 16. In this case, the lens assembly 16 and the substrate 20 can be easily positioned by inserting the protruding portion 24 into the hole 20 a provided in the substrate 20. Further, when the positioning hole 9 a is provided in the housing 9, the lens assembly 16 and the housing 9 can be easily positioned by inserting the protruding portion 24 into the positioning hole 9 a.

  It should be noted that the lens assembly 16 and the housing 9 may be screwed with screws 25 by providing a hole 24 b in the tip 24 a of the protruding portion 24. In this case, it is possible to prevent the gap between the lens assembly 16 and the housing 9 from unnecessarily spreading.

As described above, the illumination device 10 according to the first embodiment of the present invention includes the first lens group 14 for traveling mode illumination, and the second lens group 15 for passing mode illumination adjacent to the first lens group 14. Has a lens assembly 16 integrally formed and a plurality of light emitting elements 19 arranged to face the lenses 17 and 18 of the lens assembly 16, thereby realizing a traveling mode illumination and a passing mode illumination. However, it is possible to suppress a light distribution shift due to an impact or the like.

  In addition, the lamp 7 according to the first embodiment of the present invention includes the housing 9 and the illumination device 10 disposed inside the housing 9, thereby vibrating while realizing the traveling mode illumination and the passing mode illumination. And light distribution shift due to impact can be suppressed.

The vehicle 5 according to the first embodiment of the present invention includes the vehicle body 6 and the lighting device 10, thereby suppressing light distribution deviation due to vibration or impact while realizing traveling mode lighting and passing mode lighting. Can do.
(Modification)
As described above, the present invention has been described based on the specific examples shown in the above-described embodiments, but the content of the present invention is not limited to the specific examples shown in the embodiments, and various lighting devices, lamps, and It can be applied to vehicles.
1. About the driving mode illumination The lighting in the driving mode lights the light emitting element 19 disposed opposite to the lens 17 of the first lens group 14 for the driving mode illumination, and the lens 18 of the second lens group 15 for the passing mode lighting. The light emitting element 19 arranged opposite to the light emitting element 19 may be turned off, or the light emitting element 19 arranged opposite to the lens 17 of the first lens group 14 for traveling mode illumination and the lens 18 of the second lens group 15 for passing mode illumination. Both the light emitting elements 19 arranged opposite to each other may be lit. In the illumination in the traveling mode, the light emitting element 19 disposed opposite to the lens 17 of the first lens group 14 for traveling mode illumination and the light emitting element 19 disposed opposite to the lens 18 of the second lens group 15 for passing mode illumination. Can be illuminated more widely, and when applied to the vehicle 5, the range that can be visually recognized during dark driving can be expanded.
2. Regarding the boundary between the first lens group and the second lens group As shown in FIG. 5, the boundary L (two-dot chain line) between the first lens group 14 and the second lens group 15 is the center of the lens assembly 16. It is preferable to provide outside P. In this case, the lens assembly 16 can be hardly damaged by an impact or the like. The first lens group 14 and the second lens group 15 have different lenses 17 and 18, and the boundary L between the first lens group 14 and the second lens group 15 is the boundary between the lens 17 and the lens 18. Match. Therefore, since the structures of the lenses 17 and 18 sandwiching the boundary are different at the boundary between the lens 17 and the lens 18 than at the boundary between the lenses 17 or 18, the strength tends to be weak. On the other hand, the load on the line segment including the center P of the lens assembly 16 is most likely to be applied when the lens assembly 16 receives an impact. Therefore, by providing the boundary between the different lenses 17 and 18 outside the center P of the lens assembly 16, even if the lens assembly 16 receives an impact or the like, the load on the portion of the lens assembly 16 where the strength is weakest is applied. The strength of the lens assembly 16 can be improved by providing it in a portion other than the easy portion.

In particular, as shown in FIG. 6, when a lens 17 that is a condensing lens having a flat surface on the exit surface 17 a and a lens 18 that is a condensing lens having a convex surface on the exit surface 18 a are combined, each lens 17. When the projections of the exit surfaces 17a and 18a of 18 are arranged to be aligned (in other words, when the exit surface 18a is prevented from projecting more than the exit surface 17a), the outer peripheral portion 18c of the lens 18 is the exit surface 17a of the lens 17. Rather than the substrate 20 side. In order to connect such a lens 17 and the lens 18, it is possible to provide the wall part 26 as shown in FIGS. For example, in the case of the lens assembly 16, the wall portion 26 is provided along the boundary L shown in FIG. Since the wall portion 26 has a fold between the lens 17 and the wall portion 26 of the lens assembly 16 and between the lens 18 and the wall portion 26, the strength is weak against a load that is bent with this portion as a fold. turn into. Therefore, by providing the wall portion 26 outside the center P of the lens assembly 16, it is possible to improve the strength of the lens assembly 16 by providing a portion having a weak strength in the lens assembly 16 other than a portion where the load is most easily applied. it can.

  In this case, when the wall portion 26 has a portion parallel to the line segment passing through the center P of the lens assembly 16, it is preferable that the wall portion 26 straddles the line segment passing through the center P in another portion. The wall portion 26 shown in FIG. 7 is a portion parallel to a line segment passing through the center P of the lens assembly 16. On the other hand, the wall portion 26 shown in FIG. 8 is a portion straddling a line segment passing through the center P of the lens assembly 16. As shown in FIGS. 7 and 8, the thickness d <b> 2 of the wall portion 26 across the line segment passing through the center P of the lens assembly 16 is a portion parallel to the line segment passing through the center P of the lens assembly 16. The wall portion 26 is thicker than the thickness d1. Thereby, it is possible to improve the strength against the load applied with the line passing through the center P of the lens assembly as a crease, and the strength of the lens assembly 16 can be further improved.

The boundary L preferably has a bent portion. In this case, as compared with the case where the boundary L is linear, it is possible to disperse the direction in which the strength decreases, and thus the strength of the lens assembly 16 can be further improved.
3. Arrangement of the first lens group and the second lens group As shown in FIGS. 4 to 8, the arrangement of the first lens group 14 and the second lens group 15 is such that the first lens group 14 is on the upper side and the second lens group is arranged on the upper side. It is not restricted to what is arrange | positioned 15 below. For example, the first lens group 14 may be disposed on the left side, and the second lens group 15 may be disposed on the right side, or vice versa.

  For example, it is preferable that the second lens group 15 is disposed on the upper side and the first lens group 14 is disposed on the lower side. In this case, in the illumination in the traveling mode, the light emitting element 19 disposed opposite to the lens 17 of the first lens group 14 for traveling mode illumination and the lens 18 of the second lens group 15 for passing mode illumination are disposed opposite to each other. When both the light emitting elements 19 are turned on, it is difficult to form a gap between the light emitted from the first lens group 14 and the light emitted from the second lens group 15. Therefore, in the illumination in the traveling mode, it is possible to suppress the light distribution in front of the vehicle 5 from being separated and resulting in an unnatural light distribution.

Further, as shown in FIG. 5, the region of the first lens group 14 preferably includes the center P of the lens assembly 16. Since the travel mode illumination requires a light amount more than the passing mode illumination, the lenses 17 and 18 can be easily arranged when more lenses 17 of the first lens group 14 are provided than the lenses 18 of the second lens group 15. can do.
4). Lens 17 of First Lens Group 14 FIG. 9 is an enlarged cross-sectional view taken along the optical axis of the light emitting element 19 of a modified example (hereinafter referred to as “lens 27”) of the lens 17 of the first lens group 14 of the illumination device 10. Shown in The lens 27 has substantially the same configuration as the lens 17 except that the lens 27 is different from the lens 17 in that an exit surface side recess 27b is provided at the center of the exit surface 27a of the lens 27.

The lens 27 is also a condensing lens having a portion with a flat exit surface 27a. The lens 27 has the exit surface side concave portion 27b, so that when the exit surface 27a is enlarged, the flat portion of the exit surface 27a is reduced by reducing the area of the flat portion compared to the case where the exit surface 27a is only a flat portion. Can be suppressed.
5. Regarding the lens 18 of the second lens group 15 A through hole 28 is preferably provided above the lens 18 of the second lens group 15. Since the second lens group is used for passing mode illumination, it is necessary to reduce the light traveling upward from the lens 18. For example, as shown in FIG. 6, the through hole 28 is provided on the upper side of the lens 18, so that the emission surface 18 a is parallel to the optical axis direction of the light emitting element 19 or from the same direction on the upper side of the lens 18. Also, a bent portion 18d that bends toward the light emitting element 19 is formed. The light directed upward from the lens 18 has a bent portion 18d, so that when the light from the lens 18 is emitted from the emission surface 18a, compared to the case where there is no other bent portion 18d, the emission surface 18a. Since the angle of entering can be reduced, it is possible to transmit the light from the light emitting element 19 through the lens 18 and refract the light toward the upper side as compared with the case where there is no bent portion 18d. Therefore, the light distribution suitable for the passing mode illumination can be easily realized by providing the through hole 28 on the upper side of the lens 18. That is, when the lens 18 is cut in a cross section parallel to the vertical direction including the center of the lens 18, the curvature on the upper side of the lens 18 among the emission surfaces 18 a of the lens 18 is light emission of the emission surface 18 a of the lens 18. It has a portion larger than the curvature right above the element 19 (on the optical axis of the light emitting element 19). In other words, the lens 18 can easily realize light distribution suitable for the passing mode illumination by making the part exposed to the upper side adjacent through hole 28 a part of the lens 18.

  In order to use the light emitted from the lens 18 of the second lens group for the passing mode illumination, it is preferable to direct the upward light among the light incident on the lens 18 forward. In order to realize the light distribution without providing the through hole 28 adjacent to the lens 18, it is preferable to provide a flat portion or a portion inclined toward the light emitting element 19 on the upper side of the emission surface 18 a of the lens 18. That is, it is preferable that the lens 18 has a portion parallel to the optical axis of the light emitting element 19 or a portion inclined toward the light emitting element 19 from the direction parallel to the optical axis on the upper side of the emission surface 18a. As a molding method of the lens assembly 16, a mold on the exit surface 18 a side of the lens 18 and the opposite side is prepared, a material such as a resin is poured into the mold and solidified, and then the mold is removed from the lens assembly 16. Can be considered. However, if a portion inclined toward the light emitting element 19 is provided on the upper side of the exit surface 18a of the lens 18, the die release on the exit surface 18a side of the lens 18 cannot be performed.

  Therefore, by providing the through-hole 28 adjacent to the lens 18, the shape on the upper side of the exit surface 18a of the lens 18 can be produced with a mold on the opposite side to the exit surface 18a, and the die can be easily removed. In particular, when the lens 18 has a portion inclined to the light emitting element side from the direction parallel to the optical axis of the light emitting element 19 on the upper side of the emission surface 18a, the mold is further formed when the lens assembly 16 is molded. It is easy to remove.

An enlarged front view showing a state in which the cover of the lamp 7 is removed is shown in FIG. As shown in FIG. 10, in the outer peripheral portion 18 c of the lens 18, adjacent lenses 18 may overlap with each other except for a portion adjacent to the through hole 28 and an opposing portion thereof. In the region Q (region surrounded by the broken line) sandwiched between the portion adjacent to the through hole 28 of the outer peripheral portion 18c of the lens 18 and the facing portion thereof, a light distribution for passing mode illumination can be created. Other portions may have a shape in which the lenses 18 are overlapped. In this case, the area | region of the 2nd lens group 15 can be made small, and the illuminating device 10 can be reduced in size.
6). About lighting method In addition, it is preferable that the light distribution of the light radiate | emitted from the output surfaces 17a and 18a is set so that each lens 17 and 18 may correspond substantially. In this case, it is possible to prevent the irradiation region from being lost even when the light emitting element 19 facing the lens 17 or 18 is turned off during lighting due to a malfunction or the like.

Further, the light emitting element 19 facing the lenses 17 and 18 may be turned on or off step by step. In this case, the brightness of the irradiation region can be changed by simple control of turning on or off the light emitting element 19.
7). Regarding Arrangement of Light-Emitting Element 19 When the light-emitting element 19 is a substantially rectangular parallelepiped having a longitudinal direction and a short-side direction on its emission surface (not shown), the lens is arranged by arranging the longitudinal direction along the left-right direction. The light emitted from the 17, 18 can be expanded in the left-right direction. In other words, by arranging the longitudinal direction of the light emitting element 19 along a direction (horizontal direction) substantially perpendicular to the vertical direction, the lens 17,
The light emitted from 18 can be spread in the horizontal direction.

Moreover, the light emitted from the lenses 17 and 18 can be expanded in the vertical direction by arranging the light emitting element 19 so that the longitudinal direction thereof is along the vertical direction. In other words, by arranging the longitudinal direction of the light emitting element 19 along the vertical direction, the light emitted from the lenses 17 and 18 can be spread in the vertical direction.
8). About the lighting circuit Between the lens assembly 16 and the substrate 20 on which the light emitting element 19 is mounted, a storage portion 29 for storing an electronic component (not shown) of the lighting circuit for lighting the light emitting element 19 may be provided. Good. Specifically, the storage portion 29 is preferably provided at a position between the lens assembly 16 and the substrate 20 and not impeding the light of the light emitting element 19. In this case, since it is not necessary to separately provide a part for storing the electronic components of the lighting circuit other than between the lens assembly 16 and the substrate 20, the lighting device 10 can be further downsized.

  The storage portion 29 is preferably provided below the light emitting element 19. In this case, it is possible to reduce the influence of heat generated during lighting of the light emitting element 19 on the electronic components of the lighting circuit stored in the storage unit 29.

  The lighting circuit may be mounted on the substrate 20 on which the light emitting element 19 is mounted, or may be mounted on a substrate different from the substrate 20 on which the light emitting element 19 is mounted. When the electronic component of the lighting circuit is mounted on the substrate 20, it is not necessary to use another substrate different from the substrate 20, so that the wiring of the power supply line between the substrate and the substrate can be reduced. Further, when the electronic components of the lighting circuit are mounted on a substrate different from the substrate 20, it is possible to suppress the heat generated during lighting of the light emitting element 19 from being transmitted through the substrate 20.

Further, a portion corresponding to the storage portion 29 in the lens assembly 16 may be opaque. In this case, the electronic components of the lighting circuit stored in the storage unit 29 can be hidden from the emission surfaces 17a and 18a, and the aesthetic appearance from the emission surfaces 17a and 18a can be improved.
