JP 2008-238830 A

  In the vehicular lamp described in the above-mentioned “Patent Document 1”, when the light emitting element for the stop lamp located on the front side is turned on, the reflection surface of the reflector appears to shine entirely, but it is located on the rear side. When the tail lamp light emitting element is turned on, the portion of the reflecting surface of the reflector that is shaded by the reflector for the stop lamp does not appear to shine, so that the light emitting area as the tail lamp cannot be secured sufficiently. There's a problem.

  The present invention has been made in view of such circumstances, and in a vehicular lamp provided with two types of light emitting elements having different light emitting functions, the light emitting area when any of the light emitting elements is turned on. It is an object of the present invention to provide a vehicular lamp that can sufficiently secure the above.

  The present invention is intended to achieve the above object by devising the arrangement of the light emitting elements and the configuration of the reflectors.

That is, the vehicular lamp according to the present invention is
First and second light emitting elements having different light emitting functions, a first reflector for reflecting light from the first light emitting element toward the front of the lamp, and light from the second light emitting element toward the front of the lamp In a vehicle lamp comprising: a second reflector to be reflected; and a lens that is disposed in front of the first and second reflectors and controls transmission of reflected light from both reflectors.
The first light emitting element and the second light emitting element are disposed so as to face each other with respect to a first direction intersecting the lamp front-rear direction,
The first and second reflectors are arranged in a positional relationship in which the incident areas of the reflected light from these reflectors on the lens overlap each other ,
Each of the first and second light emitting elements is disposed in a plurality at a predetermined interval in the lamp front-rear direction and the second direction intersecting the first direction,
Each of the first and second reflectors has a plurality of reflecting surfaces formed at positions corresponding to the plurality of first and second light emitting elements,
Each of the first light emitting elements emits white light, and each of the second light emitting elements emits amber color,
The plurality of first light emitting elements are lit to function as clearance lamps, and the plurality of second light emitting elements are lit to function as turn signal lamps. It is.

  As an aspect of the “different light emitting function”, an aspect with different emission color, an aspect with different emission intensity, or the like can be adopted.

  As long as the “first direction” is a direction that intersects with the lamp front-rear direction, the specific direction is not particularly limited.

  The “positional relationship in which the incident regions overlap each other” may be a positional relationship in which the incident regions completely overlap each other, or may be a positional relationship in which the incident regions partially overlap each other.

  As shown in the above configuration, in the vehicular lamp according to the present invention, the first light emitting element and the second light emitting element having different light emitting functions are arranged so as to face each other. The first reflector that reflects the light and the second reflector that reflects the light from the second light emitting element are arranged in a positional relationship in which the incident areas of the reflected light to the lens overlap each other. Advantageous effects can be obtained.

  That is, in the front view of the lamp, when the first light emitting element is turned on, the incident area of the reflected light from the first reflector in the lens appears to shine, and when the second light emitting element is turned on, from the second reflector in the lens. The incident area of the reflected light appears to shine. At this time, since these two incident regions overlap each other, a sufficient light emission area can be secured.

  As described above, according to the present invention, in the vehicular lamp provided with two types of light emitting elements having different light emitting functions, a sufficient light emitting area can be ensured when any of the light emitting elements is turned on.

  In the above configuration, the first reflector and the second reflector are configured by a single member, and the reflecting surface of the first reflector and the reflecting surface of the second reflector are arranged in the lamp front-rear direction and the first direction. If the configuration is formed continuously via a ridge line extending in the second direction intersecting with, the number of parts can be reduced and the reflecting surface of each reflector can be secured to the maximum.

  In the above configuration, if a plurality of the first and second light emitting elements are arranged at predetermined intervals in the second direction, the incident area of the reflected light from each reflector in the lens is more uniformly bright. You can make it look shining.

  Alternatively, in the above configuration, if at least one first light emitting element and at least one second light emitting element are arranged in an offset state with respect to the second direction, the first and second light emitting elements Light from each can be efficiently reflected by each of the first and second reflectors.

  In the above configuration, if the first light-emitting element emits white light and the second light-emitting element emits amber color, the lens can be provided with regions that emit different colors. Thereby, the designability of the lamp can be improved.

The front view which shows the vehicle lamp which concerns on one Embodiment of this invention II-II sectional view of FIG. III-III sectional view of FIG. The figure similar to FIG. 1 which shows the vehicle lamp which concerns on the modification of the said embodiment.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a front view showing a vehicular lamp 10 according to an embodiment of the present invention. 2 is a cross-sectional view taken along the line II-II in FIG. 1, and FIG. 3 is a cross-sectional view taken along the line III-III in FIG.

  As shown in these drawings, the vehicular lamp 10 according to the present embodiment is a lamp provided at the left front end portion of the vehicle, and functions as a clearance lamp and a front turn signal lamp.

  As for the vehicular lamp 10, in FIG. 2, the direction indicated by X is “front”, and the direction indicated by Y is “right” (“left” for vehicles) orthogonal to “front”. .

  The vehicular lamp 10 includes a first and second light emitting elements 22A and 22B, a first and a second light emitting element 22A in a lamp chamber formed by a lamp body 12 and a lens 14 attached to a front end opening of the lamp body 12. 2 reflectors 24A and 24B are incorporated.

  The lens 14 is formed so as to wrap around from the left end to the right end. A plurality of lens elements 14 s are formed on the rear surface of the lens 14. Each of these lens elements 14s is constituted by a fisheye lens.

  The first light emitting element 22A is a light emitting diode that emits white light, and four light emitting diodes are arranged downward at the upper end of the lamp chamber. At this time, these four first light emitting elements 22A are arranged at regular intervals in the left-right direction and along the wraparound shape of the lens 14 so as to be displaced rearward as they are located on the right side. The four first light emitting elements 22A are mounted on a common substrate 26A, and the substrate 26A is supported by the lamp body 12.

  On the other hand, the second light emitting elements 22B are light emitting diodes that emit amber light, and four upwardly arranged at the lower end portion in the lamp chamber. At this time, these four second light emitting elements 22B are arranged so as to be located directly below each of the four first light emitting elements 22A. These four second light emitting elements 22B are mounted on a common substrate 26B, and this substrate 26B is supported by the lamp body 12.

  The first reflector 24A is a reflector that reflects the light from the four first light emitting elements 22A toward the front of the lamp, and the second reflector 24B directs the light from the four second light emitting elements 22B to the front of the lamp. It is a reflector to reflect. The first and second reflectors 24 </ b> A and 24 </ b> B are composed of a single member and are supported by the lamp body 12.

  The first reflector 24A has four reflecting surfaces 24Aa. These four reflecting surfaces 24Aa are positioned below each of the four first light emitting elements 22A and are formed with the same left-right width. Each of the reflecting surfaces 24Aa diffuses and reflects the light from each first light emitting element 22A so that it spreads to some extent downward in the vertical direction, and diffusely reflects the light so as to spread slightly to the left and right sides in the horizontal direction. have. As a result, the reflected light from each reflecting surface 24Aa reaches the lens 14 in a region close to the entire range in the vertical direction, and is slightly wider than the left and right width of each reflecting surface 24Aa in the horizontal direction. To reach this area.

  On the other hand, the second reflector 24B also has four reflecting surfaces 24Ba. These four reflecting surfaces 24Ba are formed in a vertically symmetrical shape with the four reflecting surfaces 24Aa in the first reflector 24A. That is, also in the second reflector 24B, the reflected light from each reflecting surface 24Ba reaches the region close to the entire range in the vertical direction with respect to the lens 14, and the right and left of each reflecting surface 24Ba in the horizontal direction. It is designed to reach an area slightly wider than the width.

  And these 1st and 2nd reflectors 24A and 24B are continuously formed via the ridgeline R in which the four sets of reflecting surfaces 24Ba and 24Ba extend in the left-right direction. At this time, these four sets of reflecting surfaces 24Aa and 24Ba are arranged so as to be displaced rearward as the lens 14 is located along the wraparound shape of the lens 14.

  In the vehicular lamp 10 according to the present embodiment, when the four first light emitting elements 22A are lit, substantially the entire area of the lens 14 emits light and functions as a clearance lamp, and the four second light emitting elements 22B are lit. By doing so, almost the entire region of the lens 14 emits light and functions as a front turn signal lamp.

  Next, the effect of this embodiment is demonstrated.

  In the vehicular lamp 10 according to the present embodiment, the first light emitting element 22A and the second light emitting element 22B having different light emitting functions are arranged so as to face each other in the vertical direction (that is, the first direction). The position where the first reflector 24A that reflects the light from the first light emitting element 22A and the second reflector 24B that reflects the light from the second light emitting element 22B overlap the incidence areas of the reflected light on the lens 14 with each other. Since they are arranged in a relationship, the following effects can be obtained.

  That is, in the front view of the lamp, when the first light emitting element 22A is turned on, the incident area of the reflected light from the first reflector 24A in the lens 14 appears to be lit, and when the second light emitting element 22B is turned on, the lens 14 The incident area of the reflected light from the second reflector 24B in FIG. At this time, since these two incident regions overlap each other, a sufficient light emission area can be secured.

  As described above, according to the present embodiment, in the vehicular lamp 10 including the two types of light emitting elements 22A and 22B having different light emitting functions, the light emitting area is increased when any of the light emitting elements 22A and 22B is turned on. It can be secured sufficiently.

  In addition, in the present embodiment, the first reflector 24A and the second reflector 24B are formed of a single member, and the reflection surface 24Aa of the first reflector 24A and the reflection surface 24Ba of the second reflector 24B are left and right. Since it is continuously formed through the ridgeline R extending in the direction (that is, the second direction), the number of parts can be reduced and the reflecting surfaces 24Aa and 24Ba of the reflectors 24A and 24B can be secured to the maximum. be able to.

  In the present embodiment, since the plurality of first and second light emitting elements 22A and 22B are arranged at predetermined intervals in the left-right direction, the reflected light from the reflectors 24A and 24B in the lens 14 is reflected. It is possible to make the incident region appear to shine more uniformly and brightly.

  Furthermore, in the present embodiment, the first light emitting element 22A emits white light and the second light emitting element 22B emits light in amber color. Thus, the design of the lamp can be improved.

  In the above embodiment, the first and second reflectors 24A and 24B have been described as having four reflecting surfaces 24Ba and 24Ba, respectively. However, three or less or five or more are disposed respectively. It is also possible that both are not necessarily the same number. Further, the reflecting surfaces 24Aa and 24Ba of the reflectors 24A and 24B may be configured by a single reflecting surface extending in a cylindrical shape in the left-right direction.

  In the above embodiment, it has been described that the four first light emitting elements 22A are all disposed on the upper side and the four second light emitting elements 22B are all disposed on the lower side. It is also possible to adopt a configuration that is arranged upside down.

  In the above embodiment, the first and second light emitting elements 22A and 22B are described as being arranged four by four, but it is also possible to adopt a configuration in which three or less or five or more are arranged, In that case, both do not necessarily need to be the same number.

  In the embodiment described above, the vehicular lamp 10 is a lamp provided at the left front end portion of the vehicle and has functions as a clearance lamp and a front turn signal lamp. However, the vehicular lamp 10 is provided in the vehicle. Regardless of the location and function, the same effects as in the above embodiment can be obtained by adopting the same configuration as in the above embodiment. For example, both the first and second light emitting elements 22A and 22B can be configured as tail and stop lamps as light emitting diodes that emit red light.

  Next, a modification of the above embodiment will be described.

  FIG. 4 is a view similar to FIG. 1 showing a vehicular lamp 110 according to this modification.

  As shown in the figure, in this modification, the arrangement of the first and second light emitting elements 22A and 22B and the configuration of the first and second reflectors 124A and 124B are different from those in the above embodiment.

  That is, in this modification, the four first light emitting elements 22A and the four second light emitting elements 22B are arranged in a state of being offset from each other in the left-right direction. Specifically, the four second light emitting elements 22B positioned below the four first light emitting elements 22A positioned on the upper side are arranged at positions shifted by a half pitch to the right.

  Also in this modification, the first and second reflectors 124A and 124B are formed of a single member, and have four reflecting surfaces 124Aa and 124Ba, respectively.

  However, each reflecting surface 124Aa of the first reflector 124A is formed so that the left and right widths are narrowed in a trapezoidal shape from the upper end edge to the lower end edge of the reflectors 124A and 124B below the first light emitting element 22A. On the other hand, each reflecting surface 124Ba of the second reflector 124B is formed in a trapezoidal shape such that the left and right widths are narrowed from the lower end edge to the upper end edge of the reflectors 124A and 124B above each second light emitting element 22B.

  At that time, each reflecting surface 124Aa of the first reflector 124A reflects the light from each first light emitting element 22A in parallel in the vertical direction and diffusely reflects so as to spread to the left and right sides to some extent in the horizontal direction. have. In addition, each reflecting surface 124Ba of the second reflector 124B has a reflecting surface shape that reflects and diffusely reflects light from each second light emitting element 22B in parallel in the vertical direction and spreads to some extent on the left and right sides in the horizontal direction. Have. Thus, the reflected light from each reflecting surface 124A of the first reflector 124A and the reflected light from each reflecting surface 124Ba of the second reflector 124B are made to reach the lens 14 in a state where they intersect each other in the left-right direction. It has become.

  Next, the effect of this modification is demonstrated.

  Also in the vehicular lamp 110 according to this modified example, when the first light emitting element 22A is turned on in the front view of the lamp, the incident area of the reflected light from the first reflector 124A in the lens 14 appears to shine, and the second When the light emitting element 22B is turned on, the incident area of the reflected light from the second reflector 124B in the lens 14 appears to shine. At this time, since these two incident regions overlap each other, a sufficient light emission area can be secured.

  Thus, even when the configuration of the present modification is employed, the same operational effects as those of the above-described embodiment can be obtained.

  In addition, in this modification, the light from each of the first and second light emitting elements 22A and 22B can be efficiently reflected by each of the first and second reflectors 124A and 124B.

  In the above modification, the first light emitting element 22A and the second light emitting element 22B are described as being alternately arranged in the left-right direction, but they are not necessarily arranged alternately.

  In addition, the numerical value shown as a specification in the said embodiment and its modification is only an example, and of course, you may set these to a different value suitably.
