The planar illumination unit 17 shown in FIG. 7 (c) emits light, and is configured to be visible through the cover lens member 10 from the rear of the vehicle.

  The translucent member 20 has a transparent thin plate shape having a substantially square shape when viewed from the front, and the second illumination light of the LED light emitters 15 on the back side (the vehicle front side) facing the LED light emitters 15. A second light source incident surface 20a on which L5... Is incident is provided.

  On the opposite side surface (rear side of the vehicle) of the second light source incident surface 20a, the planar illumination unit 17 having a width direction dimension W3 as shown in FIG. Are formed over substantially the entire surface of the common illumination area 16c.

The common illumination region 16c of this embodiment is located between the left and right reflector portions 13a and 13b of the tail lamp 6 in the vehicle rear view as shown in FIG. It arrange | positions so that it may adjoin to illumination area 16a, 16b and a vehicle width direction.
Then, as shown in FIG. 5, the second illumination lights L5 and L5 that have entered the translucent member 20 from the second light source incident surface 20a are partially diffusely reflected by the embossed portion 18. At the same time, the light is transmitted toward the rear of the vehicle, the inside of the common illumination area 16c is illuminated, and is visually recognized from the rear of the vehicle.
Further, as shown by a broken line in FIG. 3, the illumination light L6 from the bulb light emitter 11 is irregularly reflected by the embossed portion 18, and as shown in FIG. 7C, the inside of the common illumination region 16c is a surface. It emits light in a shape and is visually recognized from the rear of the vehicle.

  Therefore, in this embodiment, as shown in FIG. 1, the common illumination areas 16c illuminated by the planar illumination unit 17 have the left and right first illuminations provided on the left and right sides in the vehicle width direction. A multi-function illumination unit 16 is configured in a row with the regions 16a and 16b.

Further, in this embodiment, the first illumination light L6 from the bulb light emitter 11 of the tail lamp 6 enters from the one side end 20b as one first light source incident surface of the translucent member 20 to the inside. The light is incident, and is irregularly reflected by the textured portion 18 having a concavo-convex shape formed in substantially the entire region in the opposite side surface.
And the 1st illumination light L7 diffusely reflected by this embossed part 18 is light-guided toward the vehicle back, and the inside of the common illumination area | region 16c which has the width direction dimension W3 shown in FIG. The entire multifunctional illumination unit 16 is illuminated along with the ranges of the first illumination areas 16a and 16b illuminated by the reflected illumination lights L3 and L4 from the left and right reflector units 13a and 13b.

Furthermore, in this embodiment, when the first function illumination and the second function illumination are performed simultaneously, the first illumination light L7 irregularly reflected by the embossed portion 18 is along the optical path of the second illumination light L5. Along with the second illumination light L5, the light is guided toward the rear of the vehicle.
And the 1st illumination area which the inside of the range of the common illumination area | region 16c which has the width direction dimension W3 shown in FIG. 3 is illuminated more brightly, and the reflected illumination lights L3 and L4 from the said left and right reflector parts 13a and 13b illuminate. Together with 16a and 16b, as shown in FIG. 7 (d), the entire multifunctional illumination unit 16 is illuminated from the rear of the vehicle.

  Further, in the housing member 5 of the vehicle rear combination lamp device 3 of this embodiment, as shown in FIG. 4, one side end portion 20b of the translucent member 20 as the first light source incident surface, Reflective surface portions 19a and 19b that reflect the illumination lights L8 and L9 from the bulb light emitter 11 are provided toward the other side end 20c located on the opposite side of the one side end 20b in the vehicle width direction. .

  These reflecting surface portions 19a and 19b are formed to extend integrally around the left and right reflector portions 13a and 13b.

  Among these, as shown in FIG. 1, the reflection surface portion 19 a is configured so that the illumination light L <b> 8 </ b> U to L <b> 8 </ b> D from the bulb emitter 11 dispersed in the vehicle downward direction is substantially parallel light toward the one end portion 20 b. As shown, the illumination lights L10 to L11 are incident to each other so as to have a substantially arcuate shape when viewed from the front.

  The reflection surface portion 19b is provided to face the other side end portion 20c, and the illumination lights L9U to L9D enter the other side end portion 20c as incident light L12 to L13. In this way, it has a generally arcuate shape when viewed from the front, and is disposed opposite to the reflecting surface portion 19a with the bulb light emitter 11 in between.

  Next, functions and effects of the vehicle rear combination lamp device 3 according to this embodiment will be described.

In this embodiment, as shown in FIG. 3, when the bulb light emitter 11 of the tail lamp 6 is turned on in the first functional lighting state, the direct illumination light L <b> 10 passes through the cover lens member 10 to the rear of the vehicle. Visible from.
Also, the illumination lights L1 and L2 of the bulb illuminant 11 are reflected by the left and right reflector portions 13a and 13b formed on the housing member 5 to become reflected illumination lights L3 and L4, and the cover lens member 10 It is visually recognized from behind the vehicle.

At this time, the illumination light L2 passes through the space between the LED light emitters 15 and the translucent member 20 without being obstructed by other members.
Therefore, a decrease in the amount of reflected illumination light L4 reflected toward the rear of the vehicle is suppressed by the curved reflector portion 13b, and the reflected illumination light L4 and the reflected illumination light L3 or direct illumination light are suppressed. A difference in the amount of illumination is less likely to occur with L10.

Further, as indicated by a broken line in FIG. 3, the illumination light L6 from the bulb illuminant 11 having entered the translucent member 20 from the one side end 20b is incident on the second light source incident surface 20a. Is diffused by irregular reflection by the embossed portion 18 formed on the opposite side surface.
Therefore, the first illumination lights L7,... L7 having a substantially uniform light amount are guided toward the vehicle rear side of the translucent member 20 and are visually recognized from the vehicle rear side through the cover lens member 10.

  Furthermore, since the embossed portion 18 is provided on substantially the entire surface of the planar illumination portion 17, as shown in FIG. 7B, the embossed portion 18 is visually recognized through the cover lens member 10 from the rear of the vehicle. The amount of illumination light in the common illumination region 16c is substantially uniform in the area of the planar illumination unit 17 and in each part within the substantially same square shape, and is illuminated as parallel illumination light LP as shown in FIG.

  For this reason, even if the stop lamp 7 is not turned on and the translucent member 20 is not illuminated by the illumination light L5... The illumination unit 17 is illuminated by the planar parallel illumination light LP having a substantially uniform light amount by turning on the bulb light emitter 11 of the tail run 6.

  Therefore, in the first functional illumination state in which the tail lamp 6 is lit, the common illumination area 16c emits surface light along with the illumination of the first illumination areas 16a and 16b arranged adjacent to the left and right in the vehicle width direction. By illuminating, the illumination area in the lighting state of the tail lamp 6 viewed from the rear of the vehicle through the cover lens member 10 is expanded in the vehicle width direction to the width direction dimensions W1 to W3 in FIG. I can do it.

Further, in the vehicle rear combination lamp device 3, the planar light emission in the common illumination area 16 c is substantially uniform over the entire area of the planar illumination unit 17.
For this reason, the difference in the amount of illumination light at the boundary between the first illumination areas 16a and 16b and the common illumination area 16c that is the planar illumination portion 17 is reduced, and the housing member 5 is substantially at the center in the vehicle width direction. The unevenness in the amount of light due to the arrangement of the stop lamp 7 can be reduced, and the appearance quality and visibility from the rear of the vehicle can be further improved.

  Furthermore, in the vehicle rear combination lamp device 3 according to this embodiment, as shown in FIG. 4, the left and right reflecting surface portions 19a and 19b provided on the housing member 5 are used to illuminate the bulb light emitter 11. The lights L8 and L9 are collected and reflected toward the one end 20b and the other end 20c as the first light source incident surface of the translucent member 20, respectively.

  When these illumination lights L8 and L9 enter the inside of the one side end portion 20b and the other side end portion 20c of the translucent member 20, the planar illumination unit 17 illuminated by the LED light emitters 15 ... The light is diffusely reflected by the textured portion 18 formed in the common illumination area 16c and guided toward the rear of the vehicle.

  Therefore, as indicated by the dotted line in FIG. 3, the illumination light L8, the parallel illumination light LP by the first illumination light L7 incident directly from the one end 20b and irregularly reflected by the first illumination light L6 is converted into the illumination light L8, The illumination light by L9 is added and the common illumination area 16c of the planar illumination unit 17 is further visually recognized from the rear of the vehicle.

  Thus, the first illumination light L6 is attenuated by the path of the optical path in the translucent member 20, or is irregularly reflected by the embossed part 18 formed in a wide range of the planar illumination part 17, The reduced light quantity of the parallel illumination light LP by the dispersed first illumination light L7 is supplemented, and the light quantity close to the first illumination areas 16a and 16b can be viewed from the rear of the vehicle.

  Therefore, in this embodiment, the parallel illumination light LP in the range of the widthwise dimension W2 shown in FIG. 3 and the direct illumination light L10 from the same bulb light emitter 11 or the left and right reflector portions 13a and 13b, respectively. The reflected reflected illumination lights L3 and L4 can be further dimmed so as to have an approximate amount of light, and unevenness in the amount of light can be reduced.

  Accordingly, the first illumination areas 16a and 16b and the common illumination area 16c are connected in the vehicle width direction, or the planar illumination portion 17 having the width direction dimension W3 as shown in FIG. Even if the member 5 is positioned approximately in the center in the vehicle width direction, the amount of light that is visually recognized from the rear of the vehicle in the tail lamp illumination state is shared with the first illumination areas 16a and 16b, as shown in FIG. The illumination unevenness can be suppressed by combining with the area.

Further, by having the width direction dimension W3, the bulbs in which the vicinity of the first illumination regions 16a and 16b of the planar illumination unit 17 where the amount of illumination light is likely to be reduced are condensed by the left and right reflection surface portions 19a and 19b. The illumination lights L8 and L9 of the light emitter 11 are bright and visually recognized from the rear of the vehicle, and are easy to match with the illumination light amounts of the first illumination areas 16a and 16b that are arranged close to each other.
For this reason, it is possible to reduce the difference in illumination intensity between the first illumination areas 16a and 16b and the boundary portion when the planar illumination unit 17 is used as the common illumination area 16c.
Therefore, since illumination unevenness is further suppressed, the degree of freedom in layout of the vehicle rear combination lamp device 3 can be improved.

Further, as shown in FIG. 7B, the common illumination area 16c that emits surface light and the adjacent first illumination areas 16a and 16b are integrally illuminated.
For this reason, the illumination area in the first functional illumination state can be expanded to an irregular shape having a longitudinal direction in the vehicle width direction, and the function display with the planar illumination unit 17 that looks like a square shape of the stop lamp 7 The difference can be clarified also in the shape, and the visibility from the rear of the vehicle can be further improved.
Further, in this embodiment, as shown in FIG. 7B, portions of the common illumination region 16c located on and below the planar illumination unit 17 can be illuminated.
For this reason, in the tail lamp 6 illumination state, the illumination area can be continuously expanded in the vehicle width direction, and the degree of freedom in setting the design of the tail lamp 6 lighting state can be increased.

  And the common illumination area | region 16c of this tail lamp 6 and the planar illumination part 17 illuminated by the LED light-emitting body 15 ... of the stop lamp 7 which is a 2nd function illumination state as FIG.7 (c) shows. It is also used for vehicle rear view.

  For this reason, the combination efficiency of illumination areas is also good, and various types of functional illumination can be accommodated in the housing member 5 that is space-saving.

  And since the said reflective surface parts 19a and 19b shown in FIG. 4 are integrally connected and formed in the periphery of the reflector parts 13a and 13b formed in the said housing member 5, it is favorable, without increasing a number of parts. With the mounting accuracy, an accurate reflection angle can be obtained and the illumination efficiency can be improved.

  In addition, in this embodiment, the reflective surface portion 19b having a substantially arcuate shape in front view having a reflective surface on the inner side opposite to the side where the bulb light emitter 11 is disposed, which may reduce the amount of light. Is provided.

Therefore, as indicated by a two-dot chain line in FIG. 4, the first illumination light L9 from the bulb light emitter 11 that has passed through the space between the back side of the translucent member 20 and the LED light emitters 15. Is reflected by the reflecting surface portion 19b.
In the reflecting surface portion 19b, as indicated by the alternate long and short dash line in FIG. 1, the first illumination lights L9U to L9D are collected and reflected as substantially parallel reflected illumination lights L12 to L13.
The reflected illumination lights L12 to L13 are incident at an angle close to the vertical direction in the surface of the other end edge 20c of the translucent member 20 and in the outer direction.

  Therefore, it is possible to allow the light to enter the translucent member 20 with good incident efficiency, and to reduce the amount of light in the vicinity of the side surface portion 20b of the translucent member 20 located on the opposite side of the bulb light emitter 11. It is possible to suppress the illumination unevenness.

  Further, as shown in FIG. 5, in the stop lamp illumination state that is the second functional illumination state of the vehicle rear combination lamp device 3, the second light source of the translucent member 20 is turned on by lighting the LED light emitters 15. The second illumination lights L5 and L5 that are linearly incident on the inside of the light transmitting member 20 from the light incident surface 20a are illuminated as they are or partially diffusely reflected by the embossed portion 18 and directed toward the rear of the vehicle. The

  Therefore, as shown in FIG. 7C, the cover lens member is illuminated from behind the vehicle by being illuminated so as to have a plurality of circular shapes around the LED light emitters 15 in the planar illumination unit 17. 10, it is visually recognized that the lamp is in the stop lamp illumination state.

  Further, as shown in FIG. 1, the bulb light emitter 11 of the tail lamp 6 which is the first function illumination of the rear combination lamp device 3 for the vehicle, and the LED light emitter 15 of the stop lamp 7 which is the second function illumination. Are simultaneously turned on, as shown in FIG. 7 (d), the tail lamp 6 illuminates the common illumination area 16c so as to emit light in a plane, and these stop lamps 7 The stop lamp illumination by the LED light emitters 15 is visually recognized from the rear at the same time.

  In this embodiment, the LED light emitters 15 of the stop lamp 7 are located in the common illumination area 16c of the tail lamp 6, and the planar illumination part 17 is in the vehicle vertical direction as shown in FIG. The overlapping range is set, and as shown in FIG. 3, the overlapping range is also set in the vehicle width direction.

For this reason, the amount of illumination light in the planar illumination unit 17 that is illuminated in the illumination state by the LED light emitters 15 of the stop lamp 7 is further planarized by the emission of the planar illumination unit 17. The stop lamp 7 of the rear combination lamp device 3 for a vehicle can be easily viewed from a wide angle at the rear of the vehicle even if the LED light emitters 15.
Therefore, even when the stop lamp 7 is lit, it can be approximated to the planar light emission by the entire area of the planar illumination unit 17, and the irregular reflection ratio by the embossed part 18 is reduced, and the LED light emitters 15. Illumination efficiency can be improved by setting the shape of the embossed portion 18 so that the attenuation amount of the second illumination light L5.

  FIG. 6 shows a vehicle rear combination lamp device 23 as an automotive lamp of Example 1 which is a modification of this embodiment.

  Further, the first illumination light L11 of the bulb illuminant 11 having entered the translucent member 30 is reflected between the light incident flat portions 22 and 22 toward the planar illumination portion 27. Inclined surface portions 21a, 21a... Are formed.

  Further, the inclined surface portion 21 a of the mountain-shaped first light source reflecting surface 21 of Example 1 has a predetermined angle that is inclined with respect to the planar shape portion of the planar illumination portion 27.

Then, the first illumination light L11 that directly enters the light and the reflected illumination light L12 reflected by the illumination light L8 and L9 as shown in FIG. 4 of the embodiment enter the light transmitting member 30.
