Description

  The present invention relates to a vehicular illumination device that is arranged to illuminate a vehicle interior indirectly or directly, or to emit light for the purpose of decorating or illuminating a vehicle interior. The present invention relates to an illumination device for a vehicle using a light guide formed in a long rod shape.

  Conventionally, as this kind of vehicular lighting device, there exist some which were indicated in patent documents 1 or patent documents 2, for example. The light source device of Patent Document 1 emits light when a light source body incorporating an LED and light emitted from an emission hole provided in a case of the light source body is incident from an end face and guided to the inside. A light guide member called a light guide. Here, the positioning and fixing of the light guide member and the case of the light source device are performed by integrally forming protrusions (nail shapes) on a pair of opposing side walls in the vicinity of the end face of the light guide member that is injection-molded into a cylindrical shape. Is fitted into holes formed in a pair of plate-like portions provided in the case of the light source device.

JP 2009-199872 A JP 2013-86534 A

  In the lighting device disclosed in Patent Document 1, when a long light guide is an extruded molded body having flexibility, a claw shape cannot be formed. The fixed structure cannot be adopted. In addition, after the light guide is fitted and fixed to the case, it is necessary to fix the case to the housing that houses the light guide to prevent rattling and noise and to prevent the fitting from being released. However, in this case, a two-step assembly operation is required, and the reduction in workability and the number of mounting steps is a problem.

  The lighting device disclosed in Patent Document 2 is also a two-stage set of an operation of fitting the end portion of the light guide to the receiving portion of the light guide holding member and an operation of attaching to the interior material (attached member). Since attachment operation is required, workability and reduction of installation man-hours are problems. Further, in order to fit the end portion of the light guide to the cylindrical receiving portion formed integrally with the light guide holding member, an operation for largely bending the end portion of the flexible light guide is also required. . Furthermore, there is a concern that bubbles may be generated between the core portion and the covering portion of the light guide when the light guide is greatly bent. When such bubbles are generated in the light guide, the merchantability is significantly reduced, such as light unevenness.

  An object of the present invention is an illuminating device that improves the workability of attaching a light emitting member to an end of a long light guide, and specifically, the end of the light guide is greatly bent during the work of attachment. Such an operation is unnecessary, and it is an object of the present invention to provide an illuminating device that can be fixed to a container simultaneously with an operation of attaching a light emitting member to a light guide. In other words, the illumination device is characterized in that the guide function to the mounting and fixing position of the end portion of the light guide and the light emitting member and the guide function to the mounting and fixing position of the light emitting member and the container are simultaneously exhibited. The purpose is to do.

  In order to solve the above-described problems, a lighting device according to the present invention includes a light-emitting member incorporating a light source, a light guide that guides light from the light source incident from an incident surface that is an end surface in a longitudinal direction, A lighting device comprising a light emitting member and a housing for housing the light guide, wherein the light emitting member is recessed in a direction different from a moving direction for engaging the light emitting member with the housing. The different direction is set to a direction in which the end portion of the light guide body is bent and fitted into the receiving recess by the movement of the light emitting member in the moving direction. Yes.

  According to the illuminating device, since the fitting between the receiving recess of the light emitting member and the end of the light guide and the engagement and fixing of the light emitting member and the container can be performed simultaneously, two actions are required. The light emitting member assembly operation can be completed in one action. That is, a guide function to the fitting and fixing position between the light guide and the light emitting member and a guide function to the engagement and fixing position between the light emitting member and the container can be achieved at the same time. Therefore, the assembly workability is improved and the number of man-hours required for the assembly work can be reduced. In addition, since it is not necessary to bend the end of the light guide significantly when fitting the light guide to the receiving recess of the light emitting member, bubbles are formed between the core portion and the covering portion of the light guide. Problems such as light unevenness do not occur.

  Preferably, in the illumination device, the housing includes a pair of guide rail portions that guide the light emitting member when the light emitting member is moved in the moving direction, and the light emitting member has the moving direction. A locking piece is formed which is locked to the container when moving in the opposite direction and prevents movement in the opposite direction. According to this configuration, the moving direction of the light emitting member on the container is defined by the guide rail portion formed on the container and the locking piece of the light emitting member, and the light emitting member is assembled to the container. It is guided to the position, and the light emitting member can be easily engaged and fixed to the housing. At this time, the end portion of the light guide inserted into the receiving recess gradually enters the receiving recess while being bent and is guided to the fixed position.

  The locking piece may be provided rearward with respect to the moving direction with respect to the receiving recess of the light emitting member. There may be some variation in the direction of the end of the light guide, such as when the light guide is made of a flexible material. However, even in this case, the direction of the light emitting member is finely adjusted to guide the light guide. Since the light emitting member is guided to the fixed position after the end of the light body is inserted into the receiving recess of the light emitting member, the engagement between the light emitting member and the container and the fitting between the light emitting member and the light guide are performed. Can be performed simultaneously.

  The locking piece may be integrally formed with an elastic claw that can be locked in a locking hole provided in the container. According to this configuration, the light emitting member can be more reliably fixed to the container.

  The guide rail portion has an upper wall portion, a lower wall portion, and a side wall portion, and is opened inward as viewed from the moving direction so as to be surrounded by the upper wall portion, the side wall portion, and the lower wall portion. It is formed in a U-shaped cross section, and the upper wall portion may be inclined upward near the entrance where the locking piece is inserted. According to this configuration, the locking piece of the light emitting member is easily inserted and guided into the guide rail.

  According to the present invention, it is possible to improve the workability of attaching the light emitting member to the end portion of the long light guide, and specifically, it is not necessary to perform an operation for largely bending the end portion of the light guide body during the work. Simultaneously with the operation of attaching the light emitting member to the light guide, the light emitting member can be fixed to the container. That is, the function of guiding the light guide member to the mounting and fixing position of the light emitting member and the function of guiding the light emitting member and the container to the mounting and fixing position are exhibited simultaneously.

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

  FIG. 1 is a perspective view of a molded ceiling 2 called a roof trim of a vehicle to which a pair of lighting devices 1 and 1 according to a first embodiment of the present invention are attached, as viewed from the vehicle rear side. The roof trim 2 is attached to the inner surface of a roof panel that forms a roof exposed to the outside of the vehicle. The illumination device 1 emits light to decorate the ceiling of the vehicle interior as illumination, and also functions as direct illumination by irradiating light from the illumination device 1 into the vehicle interior. The lighting device 1 extends in the left-right direction at the front part along the shape, and extends in the front-rear direction in the vehicle interior at the rear part, and emits and illuminates linearly. In each illuminating device 1, light emitting members (not shown in FIG. 1) including light sources are arranged at both end portions EP indicated by circles in FIG.

  The roof trim 2 is formed with a plurality of openings OPN so that components such as an assist grip and a sun visor can be assembled. In addition, two left and right cutouts NCH with which the upper ends of the pillar trim are fitted are formed so as not to impair the appearance of the mating portion with the pillar trim attached to the pillar panel on the side of the vehicle. In FIG. 1, other components such as an assist grip and a sun visor that are modularized in the roof trim 2 other than the lighting device 1 are not shown.

  The roof trim 2 is shaped so that the left and right end portions and the front and rear end portions are curved and protrude upward. The pair of lighting devices 1 are arranged in the vicinity of the corner portion where the curve starts from the flat portion of the roof trim 2 so as to follow the vehicle front-rear direction. And the front part of these illuminating devices 1 is curving toward the vehicle width direction so that it may mutually adjoin.

  FIG. 2 is a front view of the roof trim 2 disposed in the vehicle as viewed from the side facing the vehicle interior. FIG. 3 is a sectional view taken along line AA in FIG. In addition to the above two light sources, each lighting device 1 in FIG. 2 guides light emitted from the light source shown in FIG. 3, and uniformly emits light and radiates light into the vehicle interior. A long rod-shaped light guide 3, a housing 4 that houses the light guide 3, a design lens 5 that is disposed on the side facing the vehicle interior, and a bracket (housing) that holds and fixes the housing 4 Body) 6. The light guide 3, the housing 4, and the design lens 5 are fixed to the bracket 6 as described below.

  The light guide 3, the housing 4, and the design lens 5 are fixed by attaching a locking piece 4 a extending from the housing 4 to the side of the roof trim 2 facing the roof panel (the side opposite to the vehicle interior side). It is attached and fixed by engaging with an opening 6b formed in the bracket (container) 6 that is provided. The locking pieces 4a are provided intermittently in the longitudinal direction of the housing 4, that is, in the longitudinal direction of the lighting devices 1 and 1, and the bracket 6 also has a plurality of openings 6b according to the position of the locking pieces 4a. Is formed.

  The light guide 3 is a flexible rod-shaped molded body obtained by extruding a resin so as to have a substantially circular cross section. The light guide 3 is a two-color extrusion molded body composed of a core layer and a protective layer covering the outside of the core layer. The core layer is made of an acrylic resin with a scatterer added, and the protective layer is made of a fluororesin with a scatterer added. By adopting such a configuration, flexibility is given and heat resistance when mounted can be obtained.

  An opening 2a is formed at a position where the lighting devices 1 and 1 of the roof trim 2 are provided, and at least a part of the housing 4 is accommodated in the opening 2a, and the locking claw 4a can be inserted. . The bracket 6 is formed with a recess 6a corresponding to the position where the lighting devices 1 and 1 are disposed. When the lighting devices 1 and 1 are attached by locking the locking claws 4a, the roof trim 2 is attached. The edge portion of the opening 2a is pressed by the end portion of the design lens 5, is wound into the recessed portion 6a and sinks, and is sandwiched and fixed between the design lens 5 and the bracket 6. Thereby, the edge part terminal of the opening 2a of the roof trim 2 is concealed, and is processed with good appearance. In addition, since a part of the housing 4 and the design lens 5 are accommodated in the bracket 6, the amount of protrusion to the vehicle interior side can be suppressed to the minimum necessary, so that the appearance is good and preferable.

  The housing 4 is formed with an accommodating portion 4b having a U-shaped cross section, and the above-described light guide 3 is accommodated in the accommodating portion 4b. The accommodating part 4b is formed so that the external shape of the elongate light guide 3 may be followed, and the light guide 3 is fixed and hold | maintained at the housing 4 by being fitted by the accommodating part 4b. The above-mentioned locking piece 4a is formed to extend from the arcuate top wall 42 in the accommodating portion 4b. Locking claws 40 are formed on the end portions of the side walls 44, 44 connected to the lower portion of the top wall 42 of the housing portion 4 b toward the concave outer side of the housing portion 4 b. A plurality of the locking claws 40 are provided intermittently along the longitudinal direction of the housing portion 4 b and are locked in locking holes 50 formed in each of the pair of ribs 5 a and 5 a of the design lens 5. Thus, the design lens 5 is attached and fixed to the housing 4. In addition, since each rib 5a of the design lens 5 fits in each side wall 44 of the accommodating part 4b of the housing 4, the design lens 5 and the housing 4 are positioned, and attachment workability | operativity improves. Thus, the light guide 3 is fitted into the housing portion 4b of the housing 4 and the design lens 5 and the housing 4 are engaged with each other, whereby the light guide 3 is sandwiched and fixed between the design lens 5 and the housing 4. The

  The housing 4 is molded by injection molding using a thermoplastic resin such as polypropylene or polyethylene, or a material obtained by adding a filler such as talc to these thermoplastic resins. As a result, the housing 4 can be elastically deformed, and the two side walls 44 and 44 of the housing portion 4b of the housing 4 are bent to the inside of the housing portion 4b, so that the latching claw 40 can be easily inserted into the latching hole 50 of the design lens 5. Can be locked to.

  The design lens 5 is formed by injection molding a thermoplastic resin. In the present embodiment, the one made translucent by adding scattering particles to transparent polycarbonate (PC) is used. By adding the scattering particles, the light scattering property is enhanced, and by making it semi-transparent, the inside of the lighting devices 1 and 1 becomes difficult to visually recognize, and the design property is improved. The transmittance of the design lens 5 is preferably 50 to 90%. However, when priority is given to the purpose of reducing the visibility of the lighting device 1 and 1, the content is preferably 50 to 60%.

  FIG. 4 is an exploded view showing a state before the light emitting member 7 incorporating the light source is assembled to the bracket 6 at the positions where the light sources surrounded by the circles in FIG. FIG. 5 is a perspective view showing a state after the light emitting member 7 is assembled to the bracket 6. 6 is an enlarged perspective view of the light emitting member 7 of FIG. 4, and FIG. 7 is an exploded perspective view of the light emitting member 7 of FIG.

  In FIG. 4, a notch 6c is formed at the end of the bracket 6 corresponding to both ends EP of the lighting device 1 on the opposite side to the vehicle interior, and is guided so as to be exposed upward from the notch 6c. The end 31 of the light body 3 is exposed. At this time, the light guide 3 is formed to be longer than the housing 4 and the design lens 5, and only the end portion 31 of the light guide 3 is exposed from the housing portion 4 b of the housing 4. In FIG. 4, the end 31 of the light guide 3 is slightly curved in advance, and the end surface 31 a is protruded.

  As clearly shown in FIG. 6, the light emitting member 7 is formed with a cylindrical receiving portion 7a, and the end portion of the light guide 3 is placed in the receiving recess 7b formed of the hollow portion of the receiving portion 7a shown in FIG. 31 is inserted and fixed. Further, as shown in FIGS. 6 and 7, the light emitting member 7 has a substrate 9 on which an LED 8 as a light source is mounted from an opening opposite to the side where the receiving portion 7a of the light emitting member 7 is formed. It is locked and covered with a cap 10 and fixed to the light emitting member 7. A locking hole 10 a is formed in the cap 10, and the locking claw 7 c formed to protrude from the light emitting member 7 is locked in the locking hole 10 a, so that the cap 10 is fixed to the light emitting member 7. The LED 8 is mounted at a position facing the receiving recess 7 a on the substrate 9, and the LED 8 and the end face 31 a of the light guide 3 are opposed to each other in the light emitting member 7. As shown in FIG. 7, a connecting portion 9 a for connecting to the harness 52 protrudes from the substrate 9, and the connecting portion 9 a is fitted to the connector portion 7 d of the light emitting member 7, whereby the substrate 9 and the light emitting member are connected. 7 is positioned and fixed. The harness is connected to the connection portion 9a in the connector portion 7d. An electrical component 54 such as a power supply device or a control device is disposed above the bracket 6 shown in FIG. 4, and the harness 52 is connected to the connection portion 9a. Therefore, since the light guide 3 is disposed below the electrical component 54, the end 31 of the light guide 3 is bent upward and connected to the light emitting member 7.

  As the light source incorporated in the light emitting member 7, either a single color LED such as blue, red, or white or a full color LED is preferably used, but in this embodiment, a full color LED is used. According to this, the full color LED is preferable because the light emission color of the light guide can be arbitrarily set and switched, so that the user can select a favorite color. Further, in the present embodiment, the light source illuminates the entire interior of the light guide 3 uniformly to directly illuminate the interior of the vehicle. However, the present invention is not limited to this, and the luminance is gradually lowered or brightened. Gradation lighting such as changing the state from a dark state to a bright state again may be used. Furthermore, you may set the brightness | luminance and color of LED which are accommodated for every light emitting member arrange | positioned at the both ends of the light guide 3 so that a specific color may be light-guided in order. As a result, various illumination effects can be produced.

  In this embodiment, since a full-color LED is used as the light source, the light emitted from the three color (RGB) LEDs is not completely mixed in the vicinity of the light incident part (end surface 31a of the light guide 3). For example, it emits pinkish light and does not emit light in a desired white color. Therefore, in order to eliminate such problems, a light shielding tape (not shown) having a width of 11 mm and a length of 25 mm is bonded to the end portions 31 at both ends of the light guide 3. The shading tape has a black inner surface and can absorb light, and the outer surface is white so as not to impair the appearance. The light shielding tape is an adhesive tape whose inner surface has adhesiveness, and is partially overlapped and stuck on the outer periphery of the end portion 31 of the light guide 3. At this time, the light shielding tape is stuck on the outer periphery of the end 31 of the light guide 3 at a position about 1 mm inside from the edge of the light guide. With this sticking position, when the end portion 31 of the light guide 3 is fitted into the receiving recess 7b of the light emitting member 7, the light shielding tape can be prevented from being caught by the side wall of the receiving portion 7a and being peeled off.

  Referring again to FIG. 4, a thin plate-like locking piece 7 e is integrally formed at the lower portion of the light emitting member 7, and the locking piece 7 e moves along a pair of guide rail portions 6 d formed on the bracket 6. The light emitting member 7 is fixed to the bracket 6 by moving (sliding) in the direction P and being locked. Further, the locking piece 7e is formed with a flexible elastic claw 7f. The elastic claw 7f is locked in a locking hole 6e formed in the housing 6, whereby the locking piece 7e. Is made to function as a stopper in the direction opposite to the moving direction P sliding inside the guide rail portion 6d, and at the same time, the function of positioning and fixing the light emitting member 7 to the bracket 6 is exhibited.

  8 is a front view of the bracket 6 to which the light emitting member 7 is attached as viewed from the side opposite to the vehicle interior side, that is, from the top side of the vehicle body, and FIG. 9 is a cross-sectional view taken along line BB in FIG. FIG. 10 is a cross-sectional view taken along the line CC of FIG. As shown in FIG. 9, in the housing 6, the insertion portion bottom surface 6 g into which the light emitting member 7 is inserted is formed so that the guide rail portions 6 d and 6 d are positioned one step higher, and a pair of steps 6 f and 6 f are formed. It is formed between the insertion portion bottom surface 6g and the guide rail portions 6d and 6d. The locking piece 7e is formed in a stepped shape with the center portion of the upper surface protruding downward by one step so as to correspond to the bottom surface 6g of the insertion portion, and the convex portion 7g, 7 g is formed so as to protrude downward. Since the protrusions 7g and 7g position the locking piece 7e, that is, the light emitting member 7 in the width direction with respect to the insertion direction to the bracket 6, the mounting operability of the light emitting member 7 is improved.

  As shown in FIG. 10, the receiving recess 7b is designed to have a predetermined angle θ with respect to the thin plate-like locking piece 7e. The range of θ is desirably about 20 ° to 45 °. Accordingly, the end portion 31 of the light guide 3 that is curved and protrudes from the housing 4 as described above in accordance with the movement (sliding) parallel to the locking piece 7e of the light emitting member 7 enters the receiving recess 7b. Let me insert.

  Each guide rail portion 6d is opened inward as viewed in the moving direction P shown in FIG. 4, and is formed in a U-shaped cross section including an upper wall portion 6d1, a side wall portion 6d2, and a lower wall portion 6d3. In the vicinity of the insertion opening 62 of the portion 6d, the upper wall portion 6d1 is inclined so that the opening expands in the direction opposite to the moving direction P. Thereby, since the locking piece 7e is smoothly guided into the guide rail portions 6d and 6d, the mounting workability of the light emitting member 7 is improved. Moreover, since the light emitting member 7 can be lifted and moved up and down even when the locking piece 7e is partially inserted into the guide rails 6d and 6d by expanding the opening, the light guide 3 Even when the position is displaced, for example, the light emitting member 7 can be finely adjusted up and down as described above to guide the end portion 31 of the light guide 3 into the receiving portion 7a.

  Further, the locking piece 7e is behind the receiving recess 7b with respect to the moving direction P (sliding direction: right side of FIG. 4) of the light emitting member 7 when the light emitting member 7 is attached to the bracket 6. Is formed. For this reason, after engaging the end 31 of the light guide 3 with the receiving recess 7b, the locking piece 7e can be brought into contact with the guide rail 6d. Thereafter, the end 31 of the light guide 3 is inserted into the receiving portion 7a by sliding of the light emitting member 7, and at the same time, the locking piece 7e is guided to the locking position on the guide rail 6d. The elastic claw 7f formed on the locking piece 7e is locked in the locking hole 6e of the bracket 6, and the light emitting member 7 is fixed to the bracket 6. At this time, the end 31 of the light guide 3 is also inserted to an appropriate position while being slightly bent in the receiving recess 7b. Thus, the light emitting member 7 and the bracket 6 are positioned, and the light emitting member 7 and the light guide 3 are positioned.

  As described above, the elastic claw 7f of the light emitting member 7 shown in FIG. 9 is engaged with the engagement hole 6e of the bracket 6, and the step shape of the engagement piece 7e and the step shape of the guide rail portions 6d and 6d, that is, the step 6f. , 6f are fitted to each other, whereby the light emitting member 7 is positioned and fixed. Also, as shown in FIG. 10, the receiving recess 7b, which is the internal space of the cylindrical receiving portion 7a formed in the light emitting member 7, becomes narrower as it goes inward (leftward in FIG. 10) from the opening. It is formed in a tapered shape. Thereby, since the position regulation and positioning of the light guide 3 are performed, the distance between the LED 8 and the end face (incident surface) of the light guide 3 can be appropriately maintained.

  As shown in FIGS. 4 and 10, when the light emitting member 7 is engaged, the locking piece 7e extends from the insertion opening 62 of the guide rail portion 6d to the space between the upper wall portion 6d1, the side wall portion 6d2, and the lower wall portion 6d3. In addition, the locking piece 7e is inserted in a state inclined with respect to the moving direction P. Thereafter, after the end 31 of the light guide 3 is fitted in the receiving recess 7b, the locking piece 7e is made parallel to the moving direction P, and the light emitting member 7 slides on the guide rail 6d.

  With the above configuration, conventionally, an operation of engaging the light emitting member with the housing after fitting the light guide to a member (hereinafter simply referred to as a receiving recess) corresponding to the receiving portion 7a of the present embodiment. Although two actions of performing were necessary, in this embodiment, since the mounting operation of the light emitting member to the light guide body and the housing body is one action, the mounting workability is improved as compared with the conventional one. Further, conventionally, since it has been necessary to fit the end portion 31 of the light guide to the receiving portion once at a position away from the assembly position of the light emitting member, the end portion 31 of the light guide is temporarily enlarged. There is a problem in that it is necessary to bend and bubbles are generated between the coating layer and the core layer of the light guide, causing light unevenness and the like, and the light guide cannot emit light uniformly. By doing so, the bending (curving) of the end portion 31 of the light guide can be suppressed to such an extent that the bubbles are not generated, and such a problem can be solved.

  The present invention is not limited to the above-described embodiments, and various additions, changes, or deletions can be made without departing from the gist of the present invention. For example, as in the second embodiment shown in FIG. 11, the elastic claw 70 f formed on the locking piece 70 e of the light emitting member 70 is locked not by the locking hole formed in the housing 60 but by a triangular cross section. The shape projection 60g may be used. Further, the pair of guide rail portions 60d, 60d are formed so as to have different vertical heights, and the locking piece 70f and the light emitting member 7 are attached to the housing 60 in an inclined state. The receiving portion 70a formed integrally with the light emitting member 70 is unevenly distributed in the light emitting member 70 so as to be arranged closer to the higher one in the vertical height of the guide rail portion 60d, that is, closer to the x direction shown in the drawing. Formed. Thus, what changed the position and the shape arbitrarily according to convenience, such as the layout of a vehicle interior, is also contained in this invention.
