Abstract
Description
Technical Field
[0001] The present invention relates to vehicle lamps.
Background Art
[0002] Conventionally, as vehicle lamps mounted on vehicles, those combining a light source such as a light-emitting diode (LED) and a light guide such as a plate shape or a rod shape are known (see, for example, Patent Documents 1 and 2 below).
[0003] In such vehicle lamps, the light emitted from the light source is incident from the base end side of the light guide, and while repeatedly reflecting inside the light guide, the light is guided toward the tip end side of the light guide. Further, the light reflected by a plurality of reflection cuts provided on the back side of the light guide is emitted from the front side of the light guide. Thereby, it is possible to cause the light emitting portion provided on the front side of the light guide to emit light in a line shape or a planar shape.
[0004] By the way, Patent Documents 1 and 2 below disclose vehicle lamps that convert an LED light source into a linear light emitting portion. Specifically, a vehicle lamp capable of converting the condensed light traveling in a direction parallel to the optical axis into a linear light emitting portion formed by the light emitted from a rectangular end face is disclosed.

Summary of the Invention
Problems to be Solved by the Invention
[0006] However, the vehicle lighting devices described in Patent Documents 1 and 2 mentioned above can only emit light in one direction, making it difficult to emit light in the viewing angle direction in addition to the main light distribution.

[0015] Furthermore, in the drawings shown below, an XYZ Cartesian coordinate system is set up, with the X-axis direction representing the front-to-back direction of the vehicle light fixture 1, the Y-axis direction representing the left-to-right direction of the vehicle light fixture 1, and the Z-axis direction representing the up-to-down direction of the vehicle light fixture 1.
[0016] The vehicle lighting device 1 of this embodiment applies the present invention to a turn signal lamp that flashes orange light, which is part of a headlamp unit mounted on both corners of the front end of a vehicle (not shown) (in this embodiment, the left front end corner).
[0017] In the vehicle lighting device 1 of this embodiment, the turn signal lamp is set with the position when viewed from the front of the vehicle as 0°, and the legally mandated light distribution angle (visibility angle) is set within an angular range of +80° outward in the vehicle width direction, -45° inward, and ±15° vertically.
[0018] As shown in Figures 1 and 2, the vehicle lamp 1 of this embodiment comprises a light source 2 and an inner lens 3, and these are arranged inside a lamp body (not shown).
[0019] The light fixture consists of a housing with an open front and a transparent outer lens (cover lens) that covers the opening of the housing. In addition to the light source 2 and inner lens 3 mentioned above, other components such as extensions and brackets can be placed inside the light fixture, and these components can be attached to the inside of the light fixture.
[0020] Furthermore, the light fixture has an outer lens that is inclined in the direction that the outer side recedes more than the inner side in the vehicle's width direction (hereinafter referred to as the "vehicle width direction"), in accordance with the slant shape applied to the front corner of the vehicle. The shape of the light fixture can be changed as appropriate to match the vehicle's design, etc.
[0021] As shown in Figures 3, 4, and 7-10, the light source 2 consists of a light-emitting element such as an LED that emits orange light (hereinafter referred to as "light") L. The light source 2 is mounted on one side of a circuit board (not shown) on which a drive circuit (not shown) that drives the light source 2 is provided, and emits light L radially toward the front (+X axis side) of the vehicle light fixture 1.
[0022] The inner lens 3 is a light guide that directs the light L emitted from the light source 2, and is made of a light-transmitting material such as a transparent resin like polycarbonate or acrylic, or glass.
[0023] As shown in Figures 1 to 11, the inner lens 3 includes a plate-shaped first light guide portion 4 extending from one end to the other where the light source 2 is located, a rod-shaped second light guide portion 5 protruding from at least one surface (the upper surface in this embodiment) of the first light guide portion 4 and extending from one end to the other, and a third light guide portion 6 protruding from at least one surface (the upper and lower surfaces in this embodiment) of the first light guide portion 4 and located on one end side of the first light guide portion 4 and the second light guide portion 5.
[0024] In this embodiment, as shown in Figures 3, 7, and 9, one end of the inner lens 3 is located on the outside in the vehicle width direction, and the other end of the inner lens 3 is located on the inside in the vehicle width direction. The inner lens 3 is arranged in a tilted state so that, in a top view or bottom view, one end of the first light guide portion 4 is located further back than the other end, in accordance with the direction of inclination of the slant shape described above. Furthermore, as shown in Figures 1 and 2, the inner lens 3 is arranged in a tilted state so that, in a front view or rear view, one end of the first light guide portion 4 is located higher than the other end.
[0025] As shown in Figures 1 to 3, 6, 7, and 9, the first light guide portion 4 has a constant thickness and a pointed shape in which its width in the front-to-back direction gradually decreases from one end to the other.
[0026] The second light guide portion 5 has a shape in which the height in the thickness direction of the first light guide portion 4 gradually decreases from one end to the other end of the first light guide portion 4, and overlaps with the first light guide portion 4 in the thickness direction at the other end of the first light guide portion 4. Furthermore, the second light guide portion 5 is located between the front and rear directions of the first light guide portion 4 and has a shape in which the width in the front and rear direction is substantially constant from one end to the other end.
[0027] The third light guide portion 6 has a certain thickness and is provided protruding from the upper and lower surfaces of the first light guide portion 4 so as to connect one end of the first light guide portion 4 and one end of the second light guide portion 5.
[0028] The inner lens 3 has an incident portion 7 located on the back side of the first light guide portion 4 and the third light guide portion 6, a reflecting portion 8 located on the front side of the third light guide portion 6, a first emission portion 9 located on the front side of the first light guide portion 4, and a second emission portion 10 located on the other end side of the second light guide portion 5.
[0029] The incident portion 7 is located on the side of the first light guide portion 4 and the third light guide portion 6 that faces the light source 2, and has a lens shape that focuses the light L emitted from the light source 2 towards the optical axis while incident on the inside of the first light guide portion 4 and the third light guide portion 6.
[0030] Specifically, as shown in Figures 9 and 10, the incident portion 7 has a first light-gathering incident surface 7a located on the central side of the portion facing the light source 2 and curved convexly toward the light source 2 side; a second light-gathering incident surface 7b located on the outer periphery of the first light-gathering incident surface 7a and inclined to gradually widen in diameter toward the light source 2 side from a position surrounding the first light-gathering incident surface 7a; and a light-gathering reflective surface 7c located on the outer periphery of the second light-gathering incident surface 7b and inclined to gradually widen in diameter toward the opposite side of the light source 2 from a position surrounding the second light-gathering incident surface 7b.
[0031] In the incident section 7, the light L emitted from the light source 2 that enters the first light guide section 4 and the third light guide section 6 from the first light-gathering incident surface 7a is focused closer to the optical axis. On the other hand, the incident light L that enters the first light guide section 4 and the third light guide section 6 from the second light-gathering incident surface 7b is reflected by the light-gathering reflection surface 7c, thereby focusing it closer to the optical axis.
[0032] As a result, the incident section 7 aligns (collimates) the light L emitted radially from the light source 2 as it enters the interior of the first light guide section 4 and the third light guide section 6. The light L incident from the incident section 7 is guided through the interior of the first light guide section 4 and the third light guide section 6 toward the front sides of the first and third light guide sections.
[0033] As shown in Figures 3, 4 and 7, 8, the reflective section 8 has first reflective surfaces 8a and 8b on the upper and lower front sides of the third light guide section 6, flanking the first light guide section 4, and a second reflective surface 8c adjacent to the first reflective surface 8a on the upper front side of the third light guide section 6, flanking the first light guide section 4.
[0034] The first reflective surfaces 8a and 8b are composed of inclined surfaces that are tilted at an angle that reflects a portion of the light L (hereinafter distinguished as "first light") L1 incident from the incident section 7 from one end to the other of the first light guide section 4.
[0035] Of these, the upper first reflective surface 8a reflects the first light L1 toward the back side of the first light guide 4, which is located diagonally downward from above the third light guide 6. On the other hand, the lower first reflective surface 8a reflects the first light L1 toward the back side of the first light guide 4, which is located diagonally upward from below the third light guide 6.
[0036] Furthermore, the inner lens 3 is located on the back side of the first light guide section 4 and has third reflective surfaces 11a and 11b that reflect the first light L1 reflected by the first reflective surfaces 8a and 8b toward the first emission section 9.
[0037] The third reflective surfaces 11a and 11b are composed of inclined surfaces that are tilted in opposite directions on the back side of the first light guide 4. Of these, the lower third reflective surface 11a reflects the first light L1 reflected by the upper first reflective surface 8a toward the front side of the first light guide 4. On the other hand, the upper third reflective surface 11b reflects the first light L1 reflected by the lower first reflective surface 8b toward the front side of the first light guide 4. As a result, the first light L1 reflected by the third reflective surfaces 11a and 11b is guided through the interior of the first light guide 4 toward the first emission section 9 located on the front side of the first light guide 4.
[0038] The second reflective surface 8c is composed of an inclined surface that is tilted at an angle that reflects a portion of the light L (hereinafter distinguished as "second light") L2 incident from the incident part 7 from one end to the other end of the second light guide part 5.
[0039] The second light L2 reflected by the second reflective surface 8c is guided through the interior of the second light guide 5 toward the other end of the second light guide 5. For this reason, the second light guide 5 extends along the reflection direction of the second light L2 reflected by the second reflective surface 8c.
[0040] Furthermore, as shown in Figures 3, 5, and 11, the inner lens 3 is located on the other end side of the second light guide portion 5 and has a fourth reflective surface 12 that reflects the second light L2 guided inside the second light guide portion 5 toward the second emission portion 10.
[0041] The fourth reflective surface 12 is composed of an inclined surface tilted at an angle that reflects the second light L2 reflected by the second reflective surface 8c toward the second emission section 10. As a result, the second light L2 reflected by the fourth reflective surface 12 is guided through the inside of the second light guide section 5 toward the second emission section 10 located on the front side of the second light guide section 5.
[0042] As shown in Figures 3, 4, 7 to 10, the first emission section 9 has a plurality of emission cutouts 9a on the front side of the first light guide section 4. The plurality of emission cutouts 9a control the light distribution of the light L and the first light L1 emitted to the outside from the front side of the first light guide section 4.
[0043] For example, in this embodiment, the multiple emission cuts 9a are formed by grooves with a substantially triangular cross-section (so-called prism cuts) that cut out the front surface of the first light guide 4 in the thickness direction, and these grooves are arranged in the direction of extension of the first light guide 4. Furthermore, the multiple emission cuts 9a have a lens shape that diffuses the light L and the first light L1 emitted from the front side of the first light guide 4.
[0044] In the first emission section 9, the light L guided from the incident section 7 toward the front side of the first light guide section 4 and the first light L1 guided from the third reflective surfaces 11a and 11b toward the front side of the first light guide section 4 are each emitted to the outside from the front side of the first light guide section 4 via a plurality of emission cutouts 9a. As a result, the light L and the first light L1 emitted from the first emission section 9 are emitted as the main light distribution toward the front of the vehicle lamp 1 from the front side of the first light guide section 4.
[0045] As shown in Figures 3, 5, and 11, the second emission section 10 has a projection 10a that protrudes toward the front from the other end of the second light guide section 5 that overlaps with the first light guide section 4, and an emission surface 10b at the tip of the projection 10a.
[0046] The projection 10a is provided so as to protrude forward from a position overlapping with the other end of the first light guide 4, and ahead of the front side of the first light guide 4. The emission surface 10b is formed by the tip surface of the projection 10a. The emission surface 10b also has a lens shape that diffuses the second light L2 emitted from the tip surface of the projection 10a.
[0047] In the second emission section 10, the second light L2, which has been guided from the fourth reflective surface 12 toward the tip of the projection 10a, is emitted outwards from the emission surface 10b. As a result, the second light L2 emitted from the emission surface 10b is emitted as a secondary light distribution in the direction of the viewing angle (-45°) on the inside in the vehicle width direction.
[0048] In the vehicle lighting device 1 of this embodiment, which has the above-described configuration, the front side of the first light guide unit 4 can be made to flash orange as the light-emitting part of a turn lamp by the main light distribution light L and the first light L1 described above.
[0049] On the other hand, in the vehicle lighting device 1 of this embodiment, it is possible to add a second light L2 that is emitted in the viewing angle direction (-45°) on the inside in the vehicle width direction as a secondary light distribution.
[0050] As a result, the vehicle lamp 1 of this embodiment satisfies the light distribution of the light L and the first light L1 that are irradiated towards the front as the main light distribution, while suppressing the decrease in luminous intensity of the second light L2 that is irradiated towards the inside in the vehicle width direction at approximately -45°, and is able to satisfy the above-mentioned legally mandated light distribution angle (viewing angle).
[0051] It should be noted that the present invention is not necessarily limited to the embodiments described above, and various modifications can be made without departing from the spirit of the invention. For example, in the inner lens 3 described above, the upper first reflective surface 8a and the second reflective surface 8c, which are at different angles of inclination, are arranged adjacent to each other on the front side of the third light guide portion 6 described above. However, as shown in Figure 12, the first reflective surface 8a and the second reflective surface 8c may form a continuous inclined surface at an angle that coincides with each other.
[0052] Furthermore, in the inner lens 3 described above, the second light guide portion 5 and the second reflective surface 8c are arranged on the upper side of the first light guide portion 4, but they may also be arranged on the lower side of the first light guide portion 4, or they may be arranged on both the upper and lower sides of the first light guide portion 4.
[0053] Furthermore, the second light guide portion 5 is configured such that, from one end to the other, the height of the first light guide portion 4 in the thickness direction gradually decreases, and at the other end of the first light guide portion 4, it overlaps with the first light guide portion 4 in the thickness direction. However, the second light guide portion 5 may have a constant thickness, and may not overlap with the first light guide portion 4 in the thickness direction.
[0054] Furthermore, in the above-mentioned vehicle lighting device 1, as shown in Figure 13, a light distribution cut 21 may be provided on the outer lens (or another lens) 20 that covers the front side of the inner lens 3, and by controlling the light distribution of the second light L2 emitted from the second emission part 10 with this light distribution cut 21, the second light L2 may be emitted in the direction of the viewing angle (-45°) on the inside in the vehicle width direction.
[0055] Furthermore, in the inner lens 3 described above, the second light L2, which is guided from the fourth reflective surface 12 toward the tip of the projection 10a, is emitted to the outside from the emission surface 10b. However, as shown in Figure 14, the fourth reflective surface 12 and the projection 10a may be omitted, and the second light L2 may be emitted from the emission surface 10b provided on the other end of the second light guide 5. In addition, the emission surface 10b may be provided with a light distribution cut to control the light distribution of the second light L2 emitted from this emission surface 10b.
[0056] Furthermore, the first emission section 9 is not necessarily limited to the configuration having the multiple emission cuts 9a described above. It may also be configured with a flat emission surface on the front side of the first light guide section 4, or with a diffusion cut for diffusing the light L and the first light L1 emitted from the front side of the first light guide section 4.
[0057] In the above embodiment, the application of the present invention to the turn signal lamp described above was illustrated, but the present invention can also be suitably applied to other vehicle lighting fixtures that require lateral illumination, such as clearance lamps.
[0058] Furthermore, the vehicle lighting equipment to which the present invention can be applied is not limited to the front vehicle lighting equipment described above, but can also be applied to rear vehicle lighting equipment such as rear combination lamps. In this case, the present invention can be suitably used not only for rear turn signals, but also for vehicle lighting equipment that requires lateral illumination, such as stop lamps, taillights, and reverse lamps.
[0059] Furthermore, the color of the light L emitted by light source 2 is not limited to the orange light mentioned above; it can be changed to red light, white light, or other colors as appropriate, depending on the intended use of the vehicle's lighting fixture. [Explanation of Symbols]
