Description

  The present invention relates to a vehicular marker lamp that uses a planar light emitter as a light source and emits light from the planar light emitter to the periphery of the vehicle.

  Conventionally, a vehicular lamp using a planar light emitter as a light source is known. For example, in Patent Document 1, a lamp chamber is formed between a housing and a translucent cover, a planar light emitter made of an organic EL panel is installed in the lamp chamber, and light from the planar light emitter is collected by a reflector. Thus, there is described a lamp that emits to the rear of the vehicle through a translucent cover.

  By the way, in the case of a marker lamp that emits light from a light source to the side of the vehicle, a light distribution that does not emit light of a specific color such as red toward the front of the vehicle is required. For example, as shown in FIG. 1, in the case of the side marker lamp 6 at the front of the vehicle body or the side marker lamp 8 at the rear of the vehicle body, the maximum luminous intensity of red light in the range of 60 ° to 90 ° toward the front of the vehicle It is limited to 0.25 cd or less.

  For this reason, in the side marker lamp which uses a planar light emitter as a light source, it is necessary to make the light of the planar light emitter invisible from the front of the vehicle. Therefore, a configuration is conceivable in which a planar light-emitting body is covered with a lens, a light-shielding film is formed on a part of the lens, and the light directed to the front of the vehicle is blocked by the light-shielding film. However, according to this configuration, since the light shielding film covers the light emitting surface of the planar light emitter, the light distribution to the side of the vehicle is reduced according to the covering area, the indicator light becomes dark, and the appearance from the side of the vehicle is improved. There was a problem of a decrease.

  Accordingly, an object of the present invention is to provide a vehicular marker lamp that can efficiently distribute light from a planar light emitter around a vehicle.

  Another object of the present invention is to provide a vehicular marker lamp that can make the light of a planar light emitter invisible from the front of the vehicle without deteriorating the appearance from the side of the vehicle.

  In order to solve the above-described problems, a vehicle marker lamp according to the present invention includes a planar light emitter and a lens having an incident portion formed on a relative surface of the planar light emitter, and a triangular cross section at the incident portion of the lens. Are arranged in a state where the apex of the triangle is directed to the planar light emitter, and each prism has an incident surface on one surface in the arrangement direction for incident light from the planar light emitter, The light-shielding part which interrupts | blocks the incidence | injection of the light from a planar light-emitting body was provided in the surface on the opposite side.

  Here, the light-shielding portion of the prism functions to shield light traveling from the planar light emitter in a predetermined direction of the vehicle. Examples of the light traveling in a predetermined direction include light traveling from a planar light emitter toward the front of the vehicle, light traveling from the planar light emitter toward the vehicle upper side, and light traveling from the planar light emitter toward the vehicle side. .

  In either case, a reflective layer that reflects the light from the planar light emitter toward the adjacent prism is provided in the light shielding portion of the prism so that the light emitted from the planar light emitter can be efficiently distributed in the required direction. Is desirable. From the same viewpoint, it is preferable that the incident surface of the prism is formed on a surface including the long side of the prism having a triangular cross section.

  In the vehicle marker lamp of one embodiment, the lens includes an exit surface on the opposite side of the surface relative to the planar light emitter, and the exit surface is included on the outer surface of the vehicle window glass. In this case, the lens can be provided integrally with the vehicle window glass. As the planar light emitter, a transparent planar light emitter as a whole can be used so that the field of view of the window glass is not obstructed by the marker lamp.

It includes a prism having a triangular cross section, a plurality of prisms are arranged in the vehicle front-rear direction, and a light-shielding portion that blocks light from the planar light emitter is formed on the surface of each prism facing the vehicle rear. .

  Here, the light shielding part is preferably formed on a surface including the short side of the prism having a triangular cross section so as to cover the planar light emitter with a smaller area. That is, it is preferable to form a plurality of prisms at the incident portion of the lens so that the surface of the prism facing the rear of the vehicle has a smaller area than the surface facing the front of the vehicle. If it carries out like this, the light of a planar light-emitting body can be utilized efficiently.

  Similarly, in order to improve the light utilization efficiency, a reflection film can be provided on the light shielding portion, and the light from the planar light emitter can be reflected toward the adjacent prism by the reflection film.

  In the vehicular marker lamp of the present invention, the lens includes a projection for assembling the planar light emitter in a region excluding the prism on the surface relative to the planar light emitter. According to this configuration, it is possible to assemble a lens having a concave and convex surface with respect to the planar light emitter with no problem to the planar light emitter.

  In this case, it is preferable to provide an assembly hole through which the protrusion penetrates the planar light emitter in the non-light emitting region that does not face the prism. Or you may comprise so that the plate in which the assembly | attachment hole which penetrates protrusion was formed may be used, and a planar light-emitting body may be clamped between a lens and a plate. In either case, the lens and the planar light emitter can be easily assembled using means such as thermal caulking without damaging the planar light emitter.

  According to the vehicular marker lamp of the present invention, a plurality of prisms are arranged at the incident portion of the lens, and one surface in the arrangement direction of each prism is used as the incident surface, and the surface opposite to the incident surface is used as the light shielding portion. There is an effect that light traveling in an unnecessary direction is blocked by the light shielding portion, and light traveling in a necessary direction is incident on the incident surface, so that light from the planar light emitter can be efficiently distributed around the vehicle.

Therefore, the light traveling from the planar light emitter to the front of the vehicle can be blocked by the light-shielding portion so that it cannot be seen from the front of the vehicle, and the light traveling from the planar light emitter to the side of the vehicle is increased. There is an effect that the appearance of the light can be improved.

  Hereinafter, an embodiment in which the present invention is embodied in a side marker lamp of an automobile will be described with reference to the drawings. In the automobile 1 shown in FIG. 1, a pair of left and right front lamps 3 are installed at the front part of the vehicle body 2, and a pair of left and right rear lamps 4 are installed at the rear part of the vehicle body 2. The front lamp 3 is provided with a headlamp 5 that illuminates the vehicle front area and a side marker lamp 6 that illuminates the vehicle side area. The rear lamp 4 is provided with a rear lamp 7 that illuminates the vehicle rear area, and a side marker lamp 8 that emits light from the planar light emitter to the vehicle side area.

  The front and rear side marker lamps 6 and 8 are vehicular beacon lights that inform the existence of the host vehicle to both right and left passers or other vehicles. It is configured to emit to the side of the vehicle in an angle range of degrees. The configuration of the side marker lamp 8 of the rear lamp 4 will be described below, but the same configuration can be applied to the side marker lamp 6 of the front lamp 3.

  As shown in FIG. 2, the housing 10 of the rear lamp 4 forms a lamp chamber 12 with the translucent cover 11, a rear lamp 7 is installed rearward in the lamp chamber 12, and the side marker lamp 8 is It is installed sideways. The rear lamp 7 is provided with an LED light source unit 13, a reflector 14, and an inner lens 15. The side marker lamp 8 includes a planar light emitter 17 and a lens 18 inside a casing 16 attached to the lamp housing 10, and the light from the planar light emitter 17 passes through the lateral hole 19 of the translucent cover 11 from the lens 18 to the vehicle. It emits to the side.

  As shown in FIGS. 3 and 4, the planar light-emitting body 17 generates uniform visible light from the entire light emitting region such as an organic EL, an inorganic EL, a light guide plate, and a light emitting plate in which a plurality of LEDs are arranged. A flat or curved light emitting panel is used. The body 21 of the lens 18 is formed of a transparent resin such as acrylic or polycarbonate so as to be long in the vehicle front-rear direction, and the surface (surface) facing the vehicle body side of the lens body 21 is an emission surface 22, and the surface on the opposite side. An incident portion 23 is formed on the (rear surface), that is, the surface facing the planar light-emitting body 17.

  The exit surface 22 is smoothly mirror-finished, and a plurality of prisms 24 having a triangular cross section are formed in the entrance portion 23 in the vehicle front-rear direction. In the region excluding the prism 24, the front end portion 21a and the rear end portion 21b of the lens body 21 are formed with protrusions 25 for assembling the planar light emitter 17 and the lens 18 so as to protrude toward the lamp housing 10 side. . Then, the protrusion 25 is passed through the hole 26 of the planar light emitter 17 and the hole 27 formed in the bottom wall 28 of the casing 16, and the tip of the protrusion 25 is caulked with heat, whereby the planar light emitter 17 and the lens 18. Is assembled to the casing 16.

  In addition, when organic EL or inorganic EL is used for the planar light-emitting body 17, the electrode and the light-emitting layer sandwiched between two substrates (glass or resin) are not exposed to moisture in the air. By sealing the 26 peripheral walls with the insulating sealing agent 29, the moisture resistance performance of the planar light-emitting body 17 can be enhanced.

  Each prism 24 of the lens 18 is integrally formed with the lens body 21 so that the apex of the triangular cross section is located on the planar light emitter 17 side. The surface of the prism 24 facing the front of the vehicle is an incident surface 31 on which light from the planar light emitter 17 is incident. The surface of the prism 24 facing the rear of the vehicle is incident on the light from the planar light emitter 17. A light shielding portion 32 for shielding is formed. The light shielding portion 32 is formed on a surface including the short side of the prism having a triangular cross section. For example, a black light shielding layer 33 is applied to the surface, and the reflective layer 34 is formed so as to cover the light shielding layer 33 from the rear of the vehicle. It is attached.

  As shown in FIG. 5, in this embodiment, the prism 24 is formed in a right-angled triangle so that the light shielding part 32 covers the planar light emitter 17 with a minimum area, and the light shielding part 32 is arranged with respect to the arrangement direction of the prism 24. Formed substantially at right angles. Thereby, when the side marker lamp 8 is turned on, the peak and valley of each prism 24 appear as one straight line on the exit surface 22 of the lens 18, and the entire exit surface 22 is made uniform by the light from the planar light emitter 17. It is possible to improve the appearance of the side marker lamp 8 as seen from the side of the vehicle.

  On the other hand, the incident surface 31 of the prism 24 faces the planar light emitter 17 in a wide area, and allows a large amount of light to enter the lens body 21 from the planar light emitter 17. The reflection layer 34 of the light shielding unit 32 reflects a part of the light traveling from the planar light emitter 17 toward the front of the vehicle toward the prism 24 adjacent to the rear side, and the light shielding layer 33 is rearward from the planar light emitter 17. Absorbs some of the light going to the front so as not to be reflected forward. Therefore, the light traveling from the planar light-emitting body 17 toward the front of the vehicle can be blocked by the light blocking portion 32, and the remaining light can be emitted in a required angle range on the side of the vehicle.

  FIG. 6 shows the relationship between the exit angle (x) of the lens 18 and the angle (z) of the entrance surface 31 of the prism 24. As shown in FIG. 1, in order to set the required emission angle of the side marker lamp 8 to 30 ° in front of the vehicle, as shown in FIG. 6A, the prism 24 of the acrylic lens 18 has (z) = What is necessary is just to form the incident surface 31 of 22.3 degrees. At this time, light traveling from the planar light emitter 17 toward the front of the vehicle along the incident surface 31 is incident on the lens body 21 from a part of the incident surface 31 and corresponds to the critical angle (41.8 °) of the acrylic material. The light is refracted at an angle, and is emitted from the exit surface 22 of the lens 18 to the side of the vehicle at a required angle (x) = 30 °.

  The emission angle (x) varies depending on the type of vehicle and the installation location of the side marker lamp 8. However, when emitting red light, the red light cannot be seen from the range of 60 ° to 90 ° ahead of the vehicle in accordance with regulations. Therefore, the angle (z) of the incident surface 31 is preferably set to 35.2 ° to 6.5 ° so that the emission angle (x) is 10 ° to 60 °. In terms that the maximum luminous intensity of red light on the side of the vehicle can be further increased, it is more preferable to set the incident surface angle (z) to 22.3 ° or less so that the emission angle (x) is 30 ° or less. preferable. In consideration of both the regulation and the luminous intensity, the emission angle (x) and the incident surface angle (z) can be set to intermediate values of the above numerical values, respectively. Specifically, the actual values of the emission angle (x) and the incident surface angle (z) are shown in FIG. 6B according to the angle (θ) formed by the surface of the lens 18 (the emission surface 22) and the side surface of the vehicle body 2. ) Can be set.

Therefore, the angle (z) of the incident surface 1 is set to 15 ° so that the emission angle (x) is 45 ° which is an intermediate value between 30 ° and 60 °. The limit incident surface angle (z) when (x) = 60 ° is 6.5 ° (see the table in FIG. 6a).
(2) When the lens surface is 10 ° rearward with respect to the vehicle body side surface, the light from the planar light emitter 17 is emitted in the range of (x) = − 20 ° to 40 °, and (x) = 70 ° to 90 ° I want to make it zero in the range of °. Therefore, the angle (z) of the incident surface 31 is set to 8 ° so that the emission angle (x) is 55 ° which is an intermediate value between 40 ° and 70 °. The limit incident surface angle (z) at (x) = 70 ° is 3 °.
(3) When the lens surface is 20 ° rearward with respect to the side of the vehicle body, the light from the planar light emitter 17 is emitted in the range of (x) = − 10 ° to 50 °, and (x) = 80 ° to 90 ° I want to make it zero in the range of °. Therefore, the angle (z) of the incident surface 31 is set to 5 ° so that the emission angle (x) is 65 ° which is an intermediate value between 50 ° and 80 °. The limiting incident surface angle (z) at (x) = 80 ° is 0.8 °.

  In the planar light emitter 17 shown in FIG. 8, the non-light emitting area 37 is sandwiched between the lens 18 and the plate 40, and the light emitting area 36 is protected by the plate 40. The plate 40 includes an assembly hole 41 through which the protrusion 25 passes, and is assembled to the casing 16 together with the planar light emitter 17 by heat caulking. The planar light-emitting body 17 shown in FIG. 9 has a non-light emitting area removed so as to have a smaller area than the plate 40, and only the light emitting area 36 is sandwiched between the lens 18 and the plate 40. According to these assembly structures, since the hole is not formed in the light emitting region 36, the planar light emitter 17 and the lens 18 are easily assembled by heat caulking without causing heat loss to the light emitting layer such as the organic EL. be able to.
