  The present invention relates to a light-emitting device installed in a vehicle, and more particularly to a light-emitting device provided with a plurality of light-emitting portions to emit light at different locations.

  2. Description of the Related Art Conventionally, various light-emitting devices have been provided inside and outside a vehicle in order to enhance the design of an interior of a vehicle, an interior such as a passenger compartment, or to provide a high-class feeling. For example, emblems such as logos and car names attached to the front and rear of automobile bodies are made to emit light or illuminate. A light guide made of resin and a plurality of LEDs (light emitting diodes) as light sources on the side or rear or front of the light guide, and the light emitted from the LEDs is guided by the light guide to There is known a configuration in which an illumination function is added by shining part or all of the periphery of the (projection for design). Moreover, like the structure currently disclosed by patent document 1 or patent document 2, LED is arrange | positioned in the design convex part which comprises design parts, such as an logo of an emblem and a car name, and one of the design convex parts. A configuration in which a part or the whole is lit is known.

  For example, when the light source is arranged in the design convex portion as in Patent Document 1, the design convex portion usually has a plurality of curved or bent shapes so as to represent the shape of a car name, a logo, or the like. Therefore, it becomes difficult to guide the light emitted from the light source to the entire design convex portion. In this case, by providing a plurality of light-emitting portions that serve as light sources, the light emitted from each light-emitting portion is guided to different locations and emitted toward the target location, so that the entire design convex portion can be obtained. A structure that emits light is conceivable.

  However, when the vehicle light emitting device includes a plurality of light emitting units in this way, the light emitted from the plurality of light emitting units provided for the purpose of illuminating different portions respectively irradiates a place different from the purpose. Therefore, it becomes a problem that the target illumination effect cannot be exhibited, or that light emitted from different light emitting portions is mixed to cause unevenness of light and the like and the target illumination effect cannot be exhibited.

  Moreover, when the concave shape which can accommodate LED is provided in a light guide like patent document 2, and LED is arrange | positioned in a light guide, it will be irradiated from a different light emission part within an emblem (design convex part). Although there is a possibility that the occurrence of light unevenness due to mixing of light may be somewhat reduced, it is necessary to perform a process of providing a concave shape for housing the LED in the light guide, which increases the processing man-hours and processing cost. In addition, there is a new problem that a problem may occur during assembly due to cracks due to a decrease in the strength of the light guide, variations in the shape of the light guide, misalignment when the LED is attached, and the like.

  In addition, when light is emitted from the light source toward the emblem (design convex part) and the side surface of the emblem (design convex part) is shined without using a light guide, the main optical axis of the light source travels in the vehicle. When arranged so as to face the direction, most of the light hits the back surface of the emblem and is absorbed, which is inefficient. Conventionally, this wasted light is not utilized, but the light quantity is increased by increasing the number of light sources, but the number of parts increases, which increases the number of manufacturing steps and costs and saves space. It is a problem from the viewpoint.

The vehicle light-emitting device can achieve a target illumination effect without causing uneven light partially.

  According to a preferred embodiment, the partition wall is provided with a light blocking portion made of an opaque resin. According to this, since it becomes more difficult for light to pass through the light blocking portion, the light emitted from the first light emitting portion and the light emitted from the second light emitting portion are mixed with each other, and light unevenness occurs. The risk of doing so can be reduced.

It is possible to further reduce the occurrence of light unevenness due to mixing.

  According to a further preferred embodiment, the partition wall and the design convex portion are integrally formed. According to this, the number of parts is reduced and the work of attaching the partition wall to the design convex portion is unnecessary, so that workability is improved.

  According to another more preferable embodiment, after the partition wall and the design convex portion are formed separately, the partition wall is attached and fixed to the design convex portion. According to this, since the partition wall is attached and fixed after being formed separately from the design convex portion, the partition wall is brought close to the side wall of the design convex portion to a distance that is difficult to die-cut by integral molding. Can be arranged, and the degree of freedom in optical design of the vehicular light emitting device is greatly improved.

  According to a further preferred embodiment, there is formed a light reflecting portion that reflects the light emitted from the first light emitting portion toward the first region of the design convex portion and changes the traveling direction. It is characterized by. According to this, the light irradiated toward the projecting direction of the design convex part from the first light emitting part or the second light emitting part is reflected by the light reflecting part provided on the partition wall, and the traveling direction of the light is changed. Since it can be changed, it can be reflected in the location and direction of the target such as the side surface of the design convex portion.

  According to a further preferred embodiment, the light reflecting portion is curved or inclined so as to be closer to the second region as the distance from the first light emitting portion is further away from the first light emitting portion. It is characterized by being. According to this, it is possible to allow light to reach a place distant from the light source and to emit light, and it is possible to emit light over a wide range with only light emitted from a single light emitting unit. Can be reduced.

  According to a further preferred embodiment, the light reflecting portion is formed such that a curvature or an inclination angle of a cross-sectional shape gradually increases as the distance from the first light emitting portion increases. According to this, the reflection efficiency of the light reflecting portion can be increased.

  According to the present invention, in the vehicle light emitting device that emits light from the design convex portion by disposing the light source in the design convex portion, a plurality of light emitting portions are disposed for the purpose of causing different portions to emit light. Even if it does, uneven light does not occur.

In the present embodiment, the number of LEDs in each light emitting unit is four, but is not limited thereto.

<Light guide (inner lens)>
The light guides 12 and 12 'are formed by injection molding a transparent polymethyl methacrylate resin (PMMA). The light guide 12 is formed with a protruding portion 12b protruding backward from one end of the J-shaped main portion 12a. Further, the light guide 12 ′ is formed with a main portion 12 a ′ and a protruding portion 12 b ′ so as to be symmetrical (laterally symmetric) with the light guide 12 with respect to the center plane P.

  As shown in FIG. 3, the end surface of the projecting portion 12 b of the light guide 12 is disposed so as to face the second light emitting portion 13 b of the substrate 13 placed on the bottom surface of the recessed portion 14 b of the base portion 14. At this time, the protrusion 12b is formed so as to bend from the recess 14a to the recess 14b, and at least a part of the protrusion 12b is inserted into the recess 14b. Similarly, the end surface of the protruding portion 12b ′ of the light guide 12 ′ is disposed so as to face the second light emitting portion 13b ′ of the substrate 13, and at this time, the protruding portion 12b ′ extends from the recessed portion 14a to the recessed portion 14b.

  In FIG. 4, the relationship between the protrusion part 12b of the light guide 12 and LED of the 2nd light emission part 13b is shown with the figure seen from the side. Light is emitted from the LED of the second light emitting unit 13b toward the light incident surface 12c which is the end surface of the protruding portion 12b of the light guide 12. The light that has entered the light guide 12 is reflected by an inclined surface 12d or the like provided on the projecting portion 12b, thereby guiding the light to the main portion 12a of the light guide 12, and the entire light guide 12 Can be made to emit light almost uniformly. Since the light guide 12 'is also guided in the same manner as the light guide 12, its illustration is omitted.

<Convex for design (outer lens)>
The perspective view which looked at the convex part 11 for designs from the back side in FIG. 5 is shown. The design convex portion 11 is composed of a W-shaped back surface portion 11a and a side wall portion 11b rising from the edge of the back surface portion 11a. Is molded in two colors with a transparent resin. For example, polycarbonate (PC) is suitably used as the resin used for the design convex portion 11 and is formed by injection molding.

  As described above, the design convex portion 11 is fitted with the base portion 14 so that the storage space S is formed by the storage concave portion 11c surrounded by the side wall portion 11b of the design convex portion 11 and the concave portion 14a of the base portion 14 in FIG. It is formed. The light guides 12 and 12 ′ and the substrate 13 are accommodated in the space S. The light emitted from the first light emitting part 13a and the light emitted from the second light emitting parts 13b and 13b ′ and guided by the light guides 12 and 12 ′ are the side wall parts 11b of the design convex part 11. Emits light from the transparent part. As a result, the outer peripheral edge of the emblem illumination 1 indicated by cross hatching E in FIG. 1 emits light to obtain an illumination effect, and a unique design is imparted.

  It is preferable that an optical shape (lens pattern) such as a knurled shape or a scale shape is provided on the inner side of the side wall portion 11b of the design convex portion 11 of FIG. By giving such a shape, it is possible to improve the light diffusion effect and realize light emission in which the luminance changes gradually.

<Partition wall (reflector)>
Partition walls 15, 15 ′ forming a light blocking portion are integrally formed in the housing recess 11 c of the design protrusion 11. The partition wall 15 includes first and second light blocking portions 15a and 15c that are formed of black resin and are parallel to each other, and a third light blocking portion 15b that connects one ends of the first and second light blocking portions 15a and 15c. The other end portions of the light blocking portions 15a and 15c are not connected to each other to form an opening 15J and have a U shape when viewed from the front and back directions. The partition wall 15 ′ is symmetrical with the partition wall 15. The partition walls 15 and 15 ′ are made up of standing walls that protrude perpendicularly from the back surface portion 11 a of the design convex portion 11. In the partition wall 15 and the partition wall 15 ′, the center lines C and C ′ are not parallel to each other but are inclined and intersect each other at about 90 °. The second light blocking part 15c of the partition wall 15 and the second light blocking part 15c 'of the partition wall 15' are opposed to each other in an inclined state. When the design convex part 11 is fitted to the base part 14, the partition walls 15 and 15 'are close to the ends of the light guides 12 and 12' provided with the light incident surfaces 12c and 12c '(FIG. 4). It is fitted inside partition walls 15 and 15 'having openings, and is arranged so as to surround the vicinity of the end portion.

  As a result, it is possible to prevent the light emitted from the first light emitting unit 13a and the second light emitting units 13b and 13b ′ from being mixed with each other, and thus the first light emitting unit 13a and the second light emitting units 13b and 13b. Each of can emit light toward only the target portion. That is, it is possible to prevent the occurrence of inconveniences such as uneven light generation or partial light intensity and unnatural light emission.

  In the present embodiment, the light emitted from the first light emitting part 13a is the side wall part 11b (first side) of the central inverted V-shaped protrusion part 11d among the side wall parts 11b of the design convex part 11 of FIG. It is provided only for light emission in the area A1). The second light-emitting portions 13b and 13b ′ are irradiated toward the light guides 12 and 12 ′ to guide the light guides 12 and 12 ′, whereby the inverted V-shape of the design convex portion 11 is formed. It is used for light emission of the side wall portion 11b (second region A2) other than the protruding portion 11d. Here, the second area A2 is adjacent to the first area A1. As a result, it is possible to produce an illumination effect with different light emission modes at the inverted V-shaped protrusion 11d and other portions. For example, by changing the light emission mode such that the inverted V-shaped protrusion 11d emits light so as to have higher luminance than other parts, or only the inverted V-shaped protrusion 11d changes color or blinks. It is also possible to produce various illumination effects.

  The light blocking portions 15a, 15b, 15c, 15a ′, 15b ′, and 15c ′ in the partition walls 15 and 15 ′ are preferably formed of an opaque resin, for example, a black resin, and the light blocking portions 15a, 15b, and 15c. , 15a ′, 15b ′, and 15c ′ can absorb light, so that light does not pass through the partition walls 15 and 15 ′, thereby further reducing the possibility of uneven light. it can.

  The partition walls 15 and 15 'in the present embodiment are formed so as to have a U-shaped cross section and are arranged so as to surround the ends of the light guides 12 and 12'. However, the present invention is not limited to this. In addition, by connecting the opposing side wall portions 11b of the storage recess 11c with a single partition wall, the region where the first light emitting portion 13a is disposed and the region where the second light emitting portions 13b and 13b ′ are disposed are completely formed. You may partition into. Furthermore, it is preferable that the entire partition wall is made of black resin. Such a configuration is preferable because the light emitted from the first light-emitting portion 13a and the light emitted from the second light-emitting portions 13b and 13b ′ are not mixed in the housing recess 11c.

  FIG. 6 shows a vehicle light-emitting device according to a second embodiment of the present invention. FIG. 6 shows an arrangement state of the light guide body 112 ′ on the design convex portion 111. Of the partition walls 115 and 115 ′ provided in the storage concave portion 111 c of the design convex portion 111, the partition wall It is the perspective view which expanded and showed 115 'vicinity. Moreover, the VII-VII sectional view taken on the line of FIG. 6 is shown in FIG. 7, and the VIII-VIII sectional view taken on the line is shown in FIG. Since the partition wall 115 is symmetrical with the partition wall 115 ′, the illustration is omitted. Moreover, since components other than the partition walls 115 and 115 ′ of the design convex portion 111 are the same as those in the first embodiment, the description thereof is omitted.

  The partition wall 115 ′ in FIG. 6 is formed separately from the design convex portion 111. The partition wall 115 ′ separately formed is fixed by fitting between the locking claw 116 a ′ and the second locking claw 116 b ′ of the fixing portion 116 ′ formed by integral molding with the design convex portion 111. Has been. Similarly, the partition wall 115 is fixedly attached to the design convex portion 111. By separately forming the partition walls 115 and 115 ′, the partition walls 115 and 115 ′ can be disposed so as to be close to the side wall portion 111 b of the design convex portion 111. When the design convex part 111 and the partition walls 115, 115 ′ are integrally molded, there is a restriction that a required interval must be provided due to the requirements of the production technique such as die cutting, etc., but separate molding is required for retrofitting. As a result, there are no restrictions on molding, and the degree of freedom in optical design is greatly improved.

  As shown in FIG. 7, a first locking flange 115e ′ is formed on the outside of the third light blocking portion 115b ′ of the partition wall 115 ′, and as shown in FIG. A second locking flange 115f ′ is formed to protrude from the edge of the bottom 115d ′ opposite to the third light blocking portion 115b ′. The first locking flange 115e ′ is locked with the first locking claw 116a ′ of the fixing portion 116, and the second locking flange 115f ′ is locked with the second locking claw 116b ′ of the fixing portion 116. Thereby, the partition wall 115 ′ is fitted and fixed to the fixing portion 116 ′.

  Further, locking projections 116d 'and 116e' are formed to project from the bottom 116c 'of the fixing part 116', and through holes 115g 'and 115h' are formed on the bottom 115d 'of the partition wall 115'. ing. When the partition wall 115 ′ is press-fitted into the fixing portion 116 ′ and fitted and fixed, one locking projection 116d ′ is inserted into the through hole 115g ′, and the other locking projection 116e ′ is inserted into the through hole 115h. Therefore, the partition wall 115 ′ is positioned and the backlash of the partition wall 115 ′ is prevented from occurring.

  Returning to FIG. 6, the partition wall 115 ′ includes light blocking portions 115 a ′, 115 b ′, and 115 c ′ that are standing walls made of black resin, and includes a first light blocking portion 115 a ′ and a second light blocking portion 115 c ′. Are arranged so as to face each other, and the end portion of the first light blocking portion 115a ′ and the end portion of the second light blocking portion 115c ′ are connected by the third light blocking portion 115b ′, and the other end portions are connected to each other. Instead, an opening is formed and the partition wall 115 ′ is U-shaped. When the design convex portion 111 is fitted to the base portion 114, the partition wall 115 'is disposed so as to surround the vicinity of the end portion of the light guide 112' provided with the light incident surface 112c '. This prevents the light emitted from the first light emitting unit (13a in FIG. 3) and the light emitted from the second light emitting unit (13b, 13b ′ in FIG. 3) from being mixed, Each of the first light emitting unit and the second light emitting unit can emit light toward only the target portion. That is, it is possible to prevent the occurrence of inconveniences such as uneven light generation or partial light intensity and unnatural light emission.

  9 and 10 show a vehicle light emitting device according to a third embodiment of the present invention. FIG. 9 is a perspective view of the design convex portion 211 as seen from the storage concave portion 211c side. FIG. 10 shows that the LEDs constituting the light guides 212 and 212 ′ and the first light-emitting portion 213 a and the LEDs constituting the second light-emitting portions 213 b and 213 b ′ are placed in the housing concave portion 211 c of the design convex portion 211. It is the perspective view shown in the arrange | positioned state. In the vehicle light-emitting device according to the present embodiment, the components other than the design convex portion 211 are the same as those in the first embodiment, and thus the description thereof is omitted.

  A partition wall 215 is integrally formed in the housing concave portion 211c of the design convex portion 211 shown in FIG. The partition wall 215 extends from the vicinity of the apex of the inverted V-shaped protrusion 211d, and is bifurcated in the left-right direction in the middle, curved in a concave shape, and formed in an inverted Y shape when viewed from the back side. Has been. As shown in FIG. 10, the partition wall 215 is provided with a function of reflecting light by a light reflecting portion 215c formed of a white resin or a transparent resin with a grain. The base end portion 215d of the Y-shaped trunk of the partition wall 215 is close to the first light emitting portion 213a attached to the base portion 14 (FIG. 1). Further, the tip portions 215e of the two Y-shaped branches of the partition wall 215 are close to the second light emitting portions 213b and 213b ′, respectively, and the tip portions close to the second light emitting portions 213b and 213b ′. Light blocking portions 215a and 215b made of an opaque resin such as a black resin are formed in the vicinity of 215e. Since the light blocking portions 215a and 215b suppress the mixing of the light emitted from the first light emitting portion 213a and the light emitted from the second light emitting portions 213b and 213b ′, Uneven light is reduced.

  Moreover, as shown in FIG. 11, the side surface 215m facing the side wall portion 211b of the inverted V-shaped projection 211d of the light reflecting portion 215c may be simply inclined without being bent from the intermediate portion 215m1. By adopting such a shape, the light L1 emitted from the first light-emitting portion 213a is reflected and refracted in the same manner as in the case of being bent, and the light L2 is emitted to the side wall portion 211b of the inverted V-shaped protrusion 211d. Since it becomes easy to irradiate, it becomes possible to make the side wall part 211b of the inverted V-shaped projection part 211d emit light with high luminance. At this time, the light reflecting portion 215c is designed such that a portion from the intermediate portion 215m1 of the side surface 215m to the Y-shaped tip portion 215e is closer to the side wall portion 211b as it is farther from the first light emitting portion 213a. According to such a configuration, the light emitted from the first light emitting portion 213a is reflected and refracted to the bottom of the partition wall 215, that is, to the vicinity of the tip portion 215e where the light blocking portions 215a and 215b are formed. It becomes easy to make light reach. Thereby, the side wall part 211b of the inverted V-shaped protrusion part 211d can be made to emit light more uniformly without uneven light.

  12 is a cross-sectional view taken along line XII-XII in FIG. 10 showing the vicinity of the first light emitting portion 213a. The side surface 215m facing the side wall portion 211b of the inverted V-shaped protrusion 211d in the light reflecting portion 215c is separated from the first light emitting portion 213a in the shape of the XII-XII line cross section that is a transverse cross section along the front and back direction X. It is curved in a concave shape so as to approach the side wall portion 211b. Thereby, since most of the reflected light L2 reflected by the side surface 215m among the irradiation light L1 from the first light emitting unit 21a reaches the side wall portion 211b, the luminance is improved. By adopting such a shape, the light emitted from the first light emitting portion 213a is reflected and refracted, and it becomes easy to irradiate light to the side wall portion 211b of the inverted V-shaped protrusion 211d. The side wall portion 211b of the protruding portion 211d can emit light with high luminance. At this time, the curvature of the side surface 215m of the light reflecting portion 215c is designed to increase as the distance from the first light emitting portion 213a increases (the radius of curvature decreases). Thereby, the side wall part 211b of the inverted V-shaped protrusion part 211d can be made to emit light more uniformly without uneven light.

  As described above, according to the present invention, a plurality of light emitting portions are arranged for the purpose of causing different portions to emit light in a vehicle light emitting device that emits light from a design convex portion by disposing a light source in the design convex portion. Even if it is provided, no light unevenness occurs.

  Note that two second light emitting units 13b and 13b ′ are provided in each of the above embodiments, but may be three or more.

  In each said embodiment, although 1st area | region A1 was made into the part of the inverted V-shaped projection part 11d among the side wall parts 11b, and 2nd area | region A2 was made into the part of the other side wall part 11b, it is limited to this. Not. However, it is preferable that the first region A1 and the second region A2 that are adjacent to each other and face each other in different directions.
