A laser light source that is a semiconductor light source using a laser diode chip as the chip 22 may be used.
In the present embodiment, the case where there is one light emitting chip 22 is shown, but the number of light emitting chips 22 is not particularly limited, and a plurality of light emitting chips 22 may be provided.

(Surface light source)
The surface light source 30 is a light source that emits light used for a tail lamp, a clearance lamp, or the like that has no problem even if the amount of light is relatively low. In this embodiment, an organic EL sheet that is a sheet-like organic EL is used. .

When the surface light source 30 is used as a light source that emits light used for a tail lamp, the surface light source 30 whose emission color is red may be used, but the outer lens is made red using the surface light source 30 that emits white light. May be.
When the surface light source 30 is used as a light source that emits light used for a clearance lamp, it is preferable to use the surface light source 30 whose emission color is white.

  Specifically, as shown in the enlarged view in FIG. 3, the surface light source 30 is provided on the back surface side protective layer 31 provided on the restriction surface 41 of the surface shape restriction part 40 and the back surface side protective layer 31. The cathode 32, the electron injection layer 33 provided on the cathode 32, the electron transport layer 34 provided on the electron injection layer 33, the light emitting layer 35 provided on the electron transport layer 34, and the light emitting layer 35 are provided. A hole transport layer 36, a hole injection layer 37 provided on the hole transport layer 36, an anode 38 provided on the hole injection layer 37, and a surface side protective layer 39 provided on the anode 38 are provided.

A transparent electrode such as ITO or ATO is used for the anode 38 so that light emitted from the light emitting layer 35 can be transmitted.

  When a transparent electrode such as ITO or ATO is used for the cathode 32, a reflective film made of aluminum or the like may be provided on the back side of the back side protective layer 31, and the cathode 32 may be provided as in this embodiment. Even when an alloy of Mg and Ag is used, a reflective film made of aluminum or the like may be provided on the back side of the back side protective layer 31.

  The light emitting layer 35 may be made of an organic material containing a fluorescent material, but is made of an organometallic complex containing iridium because it has a high efficiency of converting electricity into light and can suppress the generation of heat. It is preferable to use a phosphorescent material.

  Further, transparent glass or resin can be used for the back side protective layer 31 and the front side protective layer 39, but in order to suppress deterioration of the light emitting layer 35 due to moisture, a transparent material excellent in moisture resistance is used. It is preferable to use it.

(Surface shape regulation part)
As shown in FIG. 3, the surface shape regulating unit 40 serves as a mounting unit on which the surface light source 30 is disposed, and the surface light source 30 controls light distribution from the point light source 20 in the vertical direction. It is also a part that plays the role of regulating the surface shape of the surface light source 30 so as to have a surface shape that functions as:

  For this reason, the shape of the regulation surface 41 on which the surface light source 30 is arranged is regulated by a fastening member 60 (see FIG. 2) described later along the shape of the regulation surface 41 of the flexible organic EL sheet that is the surface light source 30. When fixed on 41, the surface shape of the surface light source 30 is formed into a surface shape that can perform light distribution control as a reflector.

  Specifically, as shown in FIG. 3, the regulation surface 41 is a free curve based on a parabola when viewed in cross section, and as can be seen from FIG. 2, the regulation surface 41 is free. The curve is a column surface that continues in the horizontal direction.

  For this reason, the regulating surface 41 has only a two-dimensional change in the surface shape, and the surface light source 30 is provided without causing excessive bending of the surface light source 30 formed of the organic EL sheet. It is possible to suppress the shape of the surface light source 30 from becoming a three-dimensional complicated shape.

  The surface light source 30 that is arranged on the restriction surface 41 and whose surface shape is restricted has a surface shape similar to that of the restriction surface 41 and performs light distribution control for reflecting light from the point light source 20. Acts as a reflector.

  Specifically, as shown in FIG. 3, the surface light source 30 substantially horizontally applies the first radiated light (see the light beam L1) radiated from the point light source 20 in the vertical direction (more precisely, in the vertical direction lower side). The first reflected light (light ray LR1) reflected in the front direction is seen as the second reflected light (see light ray L2) emitted from the point light source 20 to the rear side when viewed in the vertical direction. The second reflected light (see the light beam LR2) that is reflected farther from the point light source 20 with reference to LR1), and the third emitted light (see the light beam L3) emitted forward from the point light source 20 in the vertical direction. As seen, the regulating surface 41 regulates the shape of the first reflected light (refer to the light beam LR1) to the surface shape for performing the light distribution control as the third reflected light (refer to the light beam LR3) reflected to the side closer to the point light source 20. It will be.

  When such light distribution control is performed, the second radiated light (see the light beam L2) emitted backward from the point light source 20 becomes the second reflected light (see the light beam LR2) separated from the point light source 20. Therefore, it is possible to avoid the second reflected light (see the light beam LR2) from being blocked by the bracket 50 or the like.

  Further, the reflected light is sequentially viewed in the vertical direction from the rear side to the front side, and the second reflected light (light ray) reflected toward the side far from the point light source 20 based on the first reflected light (see the light ray LR1). LR2), the first reflected light reflected substantially forward in the horizontal direction (see the light beam LR1), and viewed in the vertical direction, the first reflected light (see the light beam LR1) is reflected toward the side closer to the point light source 20 When the third reflected light (see the light beam LR3) is used, the surface shape for forming such reflected light may be a change along a gentle parabola as shown in FIG. It is possible to avoid excessive bending or the like.

  For this reason, it is possible to suppress the surface light source 30 from being damaged by applying excessive bending or the like to the surface light source 30, to improve the reliability, and to be a flexible sheet that is generally becoming commercially available. Since the organic EL sheet can be used, the cost of the surface light source 30 can be reduced.

On the other hand, although the case where the member which comprises the surface shape control part 40 is used is shown in this embodiment, the surface shape control part 40 does not need to be produced as an exclusive member.
For example, the regulating surface 41 on which the surface light source 30 is arranged is formed on the housing constituting the lamp chamber so that the surface shape of the surface light source 30 is a surface shape that can perform light distribution control as a reflector. The surface light source 30 may be fixed by a fastening member 60 (see FIG. 2).

(bracket)
The bracket 50 is a member to which the point light source 20 is attached. As shown in FIG. 3, when the bracket 50 is attached to the surface shape regulating portion 40 with a screw 51 (see FIG. 2), the point light source 20 functions as a reflector. It is designed so as to be located at a predetermined position with respect to the surface light source 30.

  Specifically, when the bracket 50 is attached to the surface shape restricting portion 40 with a screw 51 (see FIG. 2), the point light source 20 is on or near the focal line FL of the surface light source 30 that functions as a reflector. The bracket 50 is designed so as to be located at the position.

  In the case of a reflector having a paraboloid, it has a focal point, but the surface light source 30 that functions as the reflector of this embodiment has a focal line FL instead of a focal point as described above. This is because the surface light source 30 functioning as a reflector does not have a three-dimensional change like a paraboloid, and the shape change of the surface is two-dimensional.

(Fastening member)
As shown in FIG. 2, the fastening member 60 is provided on a part of the surface light source 30, and is fixed to the surface shape restricting portion 40 so as to press the surface light source 30 against the restricting surface 41, whereby the surface light source 30. Is a member that plays a role of fastening to the surface shape regulating portion 40.

FIG. 4 is a perspective view showing the surface shape restricting portion 40 and the surface light source 30.
As shown in FIG. 4, the surface light source 30 is provided with three notches 30aa along the side portion 30a in a portion (see FIG. 2) hidden by the fastening member 60 of the side portion 30a on one side. A boss (not shown) provided on the rear surface of the fastening member 60 (see FIG. 2) and protruding from the rear surface is press-fitted into the surface shape regulating portion 40 corresponding to the notch 30aa. A boss press-fit hole 42 is formed.

  Further, as shown in FIG. 4, the surface light source 30 extends along the side portion 30 b in a portion (see FIG. 2) hidden by the fastening member 60 of the other side portion 30 b, similarly to the side portion 30 a on one side. Three cutout portions 30ba are provided, and the surface shape restricting portion 40 corresponding to the cutout portion 30ba is provided on the back surface of the fastening member 60 (see FIG. 2) and protrudes from the rear surface. A boss press-fitting hole 43 into which a provided boss (not shown) is press-fitted is formed.

  For this reason, for example, the surface light source 30 is temporarily fixed on the restriction surface 41 of the surface shape restriction portion 40 with a thin double-sided tape or the like that does not appear uneven in shape, and then a boss (not shown) of the fastening member 60 is attached. When the fastening member 60 is fixed by press-fitting into the boss press-fitting hole 42 and the boss press-fitting hole 43 of the surface shape regulating part 40, the surface light source 30 is pressed against the regulating surface 41 by the rear surface of the fastening member 60. The light source 30 is firmly fastened to the regulation surface 41.

The workability is improved by performing temporary fixing with a double-sided tape or the like. For example, the notch 30aa and the notch 30ab provided in the surface light source 30 are connected to the boss (not shown) of the fastening member 60. ), The surface light source 30 is fastened to the regulating surface 41 without being temporarily fixed with a double-sided tape or the like. It is also possible.
In the above description, the fastening member 60 is provided with a boss (not shown), and the surface shape regulating portion 40 is provided with the boss press-fitting holes (the boss press-fitting hole 42 and the boss press-fitting hole 43). A boss press-fitting hole may be provided, and a boss may be provided on the surface shape restricting portion 40, and an aspect of fixing between the surface shape restricting portion 40 and the fastening member 60 may be an aspect other than the boss and the boss press-fitting hole. .

  On the other hand, as shown in FIG. 2, the fastening member 60 is formed on the front side so as to have a free-form reflecting surface 61 based on a paraboloid that functions as a reflector for the point light source 20.

FIG. 5 is a perspective view for explaining the reflecting surface 61 of the fastening member 60.
In FIG. 5, illustration of the bracket 50 and the substrate 21 of the point light source 20 is omitted, and the light emitting surface of the light emitting chip 22 is schematically shown.

  As shown in FIG. 5, the fastening members 60 provided on the respective side portions (side portion 30a and side portion 30b) of the side portion 30a on one side and the side portion 30b on the other side of the surface light source 30 A plurality of reflecting surfaces 61 are provided in multiple stages along the side portions (side portion 30a and side portion 30b) of the light source 30.

  In the present embodiment, each fastening member 60 has three reflecting surfaces 61, but the number of reflecting surfaces 61 is not particularly limited, and may be one or two, There may be four or more.

  As described above, when the reflecting surfaces 61 are provided in multiple stages, it becomes easy to design the reflecting surface 61 having an appropriate shape with different paraboloid shapes, so that the degree of freedom of light distribution control by the reflecting surface 61 can be increased. it can.

  As described above, the surface light source 30 that functions as a reflector is one that performs only light distribution control in the vertical direction with respect to the light from the point light source 20, but is a reflective surface formed on the fastening member 60. Since 61 is based on a paraboloid, as shown in FIG. 5, the light (see the light beam L5) radiated from the light emitting chip 22 (point light source 20) toward the reflecting surface 61 is converted into the horizontal direction and the vertical direction. It is possible to design the light distribution control so as to form the desired reflected light (see the light beam LR5) that is controlled as follows.

For this reason, the light intensity provided on the center side of the light distribution pattern on the screen of the stop lamp, the daytime running lamp, the turn lamp, the rear fog lamp, or the headlamp, for example, by the light reflected by the reflecting surface 61 of the fastening member 60 High luminous intensity zone can be formed.
Further, since it is possible to design the reflecting surface 61 of the fastening member 60 so as to reflect light in the viewing angle direction, the light reflected by the surface light source 30 functioning as a reflector is irradiated in the viewing angle direction. Even when this is difficult, by designing the reflecting surface 61 of the fastening member 60 so as to reflect light in the viewing angle direction, it is possible to irradiate light in a favorable viewing angle direction.

  Therefore, it is concluded about the light distribution that is difficult to form with the surface light source 30 functioning as the reflector while changing the two-dimensional surface shape so that the surface light source 30 functioning as the reflector does not have a complicated shape. Since it can form with the reflected light (refer to the light ray LR5) reflected by the reflective surface 61 of the member 60, the vehicle lamp which can obtain a favorable light distribution pattern is realizable.

  In addition, a fastening member 60 that fastens the surface light source 30 to the surface shape regulating portion 40 without providing a new member in order to form a light distribution that is difficult for the surface light source 30 as the reflector to form. Therefore, the number of parts can be reduced, and the cost of the vehicular lamp can be reduced.

  Further, as shown in FIG. 5, the light emitted from the point light source 20 to the outside of the surface light source 30 can be used by providing the fastening member 60 to the outside of the side of the surface light source 30. Since this is possible, it is possible to increase the light use efficiency of the point light source 20.

(Second Embodiment)
FIG. 6 is a perspective view for explaining the vehicular lamp of the second embodiment.
In FIG. 6, illustration of the bracket 50 and the point light source 20 is omitted.

The second embodiment is different from the first embodiment only in the configuration of the fastening member 60, and the other configurations are the same as those in the first embodiment.
Therefore, hereinafter, different points will be mainly described, and description of points similar to the first embodiment may be omitted.

Each fastening member 60 has a plurality of reflecting surfaces 61 provided in multiple stages along the transverse direction.
In the present embodiment, each fastening member 60 has three reflecting surfaces 61, but the number of reflecting surfaces 61 is not particularly limited, and may be one or two, There may be four or more.

  Thus, even if it comprises the fastening member 60, the surface which functions as a reflector using the fastening member 60 which fastens the surface light source 30 with respect to the surface shape control part 40 similarly to 1st Embodiment. Light distribution that is difficult to form with the light source 30 can be formed with the reflective surface 61 of the fastening member 60.

  In the second embodiment, since the fastening member 60 is provided so as to traverse the surface light source 30, a stop lamp or the like formed by light emitted from the surface light source 30 can be formed in a stripe shape, which is novel. It is also possible to obtain design properties.

Although the present invention has been described based on the specific embodiments, the present invention is not limited to the above embodiments.
For example, in the above-described embodiment, the case where two fastening members 60 are used has been described. Often, the number of fastening members 60 used is not particularly limited.
