[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a luminous body unit for a vehicle, for example, a luminous body unit used by being attached to the surface of a car body such as a decoration or inside a car, and an elastic mounting member used therefor.

[0002]

[Prior art]

 In recent years, it has become popular to decorate around the cockpit of a car, around a license plate, or on a radiator tag with a neon lamp. Recently, young people decorating the body and interior of a car with a wire-shaped light-emitting body (for example, trade name: Hot Wire), which is made of a polymer material mixed with a phosphor powder and used as a light-emitting medium and processed into a wire. Is increasing. This wire-shaped light-emitting body has flexibility and can be bent into a desired shape according to, for example, the periphery of a cockpit or a body line, and thus has an advantage that a desired decorative pattern can be freely formed.

[0003] Meanwhile, the above-mentioned wire-shaped light-emitting body is commercially available in the form of a set of a light-emitting body, a light-emitting drive unit that drives a light-emitting device using a vehicle-mounted battery as a power supply, and a wiring cord for connecting to a vehicle wiring. Have been. However, the commercially available product does not include any accessories for attachment, so the user attaches the wire-shaped illuminant with an adhesive tape (transparent vinyl tape etc. seems to be easy and easy to use). It was attached to the object and used. Car enthusiasts always pay extra attention to getting their car dirty, but believe that mounting the illuminant is an `` improvement '' to make the car look better. I don't seem to think anything. Also, the fact that the luminous body is active in the nighttime may actually be considered that it is only necessary to look beautiful at night. Thus, enthusiasts are sticking luminous bodies of their favorite colors to bodies and cockpits, etc., and enjoying a dreamy and comfortable car life surrounded by the illusion of light.

[0004]

[Problems to be solved by the invention]

 However, when the surroundings light up after dawn, the problem is obvious to everyone. In other words, the piece of tape used for sticking the illuminant is bare and unsightly. I have to drive. Further, when the wire-shaped light-emitting body is attached with the tape covered from the outside, the light-emitting body is easily wavy, and the poor appearance is further emphasized. At this point, enthusiasts will eventually wake up from their dreams in the face of the harsh reality and drop their shoulders appalling. It is also possible to cut the double-sided adhesive tape according to the width of the luminous body and paste it so that the tape is inconspicuous.However, the work is troublesome, and it is difficult to avoid the luminous body falling off due to insufficient adhesive strength. . It should be noted that the method of semi-permanently fixing the luminous body using a strong adhesive may cause an irreparable blow to the vehicle, and few enthusiasts implement this.

An object of the present invention is to provide a light emitting unit for an automobile which can easily and securely attach a wire-shaped light emitting member to an object to be mounted, and which does not easily cause deterioration in appearance during daytime use, and an elastic mounting member used therefor. A member.

[0006]

[Means for solving the problem and functions and effects]

 In order to solve the above-mentioned problem, the automotive illuminant unit of the present invention has a wire-like form having flexibility, and emits light by itself when supplied with electric power from the outside. It has a luminous body receiving part that is formed in a long shape following the wire-shaped luminous body with an elastic material and accommodates the light emitted from the wire-shaped luminous body in a visible state, and has an opening on the outer peripheral surface. An elastic mounting member in which a groove is formed along the longitudinal direction of the vehicle, and a peripheral portion of a vehicle-side mounting target portion having a plate-shaped peripheral portion such as a door edge, a license plate edge, a radiator grill edge, etc. Inserting into the mounting groove of the elastic mounting member from the opening of the elastic mounting member in the direction of the groove bottom while pushing and expanding it, the mounting peripheral edge is elastically deformed in the thickness direction on the inner surface in the width direction of the mounting groove. Between In this case, the wire-shaped light-emitting body is mounted along the edge of the mounting peripheral portion via an elastic mounting member. Further, the elastic mounting member of the present invention corresponds to one obtained by extracting only the elastic mounting member as a constituent element from the above-described light emitting unit for a vehicle of the present invention.

[0007] According to the configuration of the present invention, the wire-shaped light-emitting body can be obtained simply by inserting a plate-shaped mounting peripheral portion such as a door edge, a license plate edge, or a radiator grill edge into a mounting groove formed in the elastic mounting member. Can be easily attached. In addition, the fixing force is high due to the elastic clamping force acting on the inner surface of the mounting groove, and problems such as falling off are unlikely to occur. Further, since the elastic mounting member is formed as a long member that covers the wire-shaped light-emitting body in the longitudinal direction, it is hard to cause a deterioration in appearance during use during daytime.

[0008]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to examples shown in the drawings. FIG. 1 shows an automotive light emitting unit (hereinafter simply referred to as a light emitting unit) 1 according to an embodiment of the present invention. As shown in FIG. 1 (a), an automotive light-emitting unit 1 has a wire-shaped form having flexibility and includes a wire-shaped light-emitting body 3 that emits light by itself when supplied with power from the outside. This is used by attaching it to an attachment peripheral portion (door edge in this embodiment) DE such as a door edge, a license plate edge, a radiator grill edge, etc. by the elastic attachment member 2. The elastic mounting member 2 is formed of an elastic material having a light-transmitting property (which may be transparent or translucent) in a long shape following the wire-shaped light-emitting body 3, and as shown in FIG. 3 has a luminous body accommodating portion 5 for accommodating the light emitted from the light emitting device 3 in a visible state, and has a mounting groove 4 formed in the outer peripheral surface thereof formed along the longitudinal direction thereof. The mounting peripheral portion DE is relatively inserted into the mounting groove 4 of the elastic mounting member 2 while pushing and expanding the mounting groove 4 in the direction from the groove opening 8 to the groove bottom 9. By elastically sandwiching the mounting peripheral portion DE in the thickness direction, the wire-shaped light emitting body 3 can be mounted along the edge of the mounting peripheral portion DE.

The elastic mounting member 2 is configured as a flexible member that follows the shape of the mounting peripheral portion DE by using a polymer material. Thereby, the elastic mounting member 2 can be freely deformed according to the shape of the mounting peripheral portion DE, and the wire-shaped light emitting body 3 can be mounted on the mounting object of various shapes with good appearance. As such a polymer material, soft vinyl chloride is inexpensive, has high strength, and is easily used. The elastic mounting member 2 having a sectional shape as shown in FIG. 1B can be easily manufactured by extrusion molding of such a polymer material.

The luminous body housing 5 of the elastic mounting member 2 can be a housing groove 5 formed integrally with the inner surface of the mounting groove 4. In this way, the wire-shaped light-emitting body 3 can be easily mounted in the housing groove 5 from the groove opening 8 of the mounting groove 4 through the inside of the mounting groove 4. In addition, the luminous body housing part 5 may be formed as a housing hole different from the mounting groove 4, as shown in FIG.

Returning to FIG. 1 (b), when the mounting peripheral portion DE is inserted into the mounting groove 4, the elastic mounting member 2 has a distal end position 6 of the mounting peripheral portion DE in the depth direction of the mounting groove 4. These mounting grooves 4 are located closer to the groove bottom 9 than the edge 7 closer to the groove opening 8 of the wire-shaped light emitter 3 housed in the light emitter housing 5. And the luminous body housing 5 are defined.

Specifically, the housing groove 5 as the light-emitting body housing portion can be formed so as to open on one inner surface in the width direction of the mounting groove 4. The wire-shaped light-emitting body 3 is accommodated in the accommodation groove 5 in a state where the center of gravity G of the axial cross section thereof is shifted from the center position O of the mounting groove 4 in the groove width direction to the formation side of the accommodation groove 5. Then, the mounting peripheral portion DE is formed so that the leading end of the mounting peripheral portion DE enters a gap formed between the other inner side surface in the width direction of the mounting groove 4 and the wire-shaped light emitting body 3 housed in the housing groove 5. It will be inserted into the mounting groove 4. By doing so, the amount of protrusion of the elastic mounting member 2 from the distal end of the mounting peripheral portion DE accompanying the mounting of the luminous body unit 1 is reduced, the appearance is further improved, and the mounting peripheral portion DE is formed by a door edge or the like. In some cases, when the door is closed, the problem of interference with the portion adjacent to the door edge (for example, in the case of a front seat door, the front edge of the rear seat door, etc.) is less likely to occur.

When the interference with the other parts when mounted on the mounting peripheral part DE does not pose a problem, as shown in FIG. 5, the bottom space of the mounting groove 4 is defined as the luminous body accommodating part 5. A configuration may be adopted in which the tip of the mounting peripheral portion DE abuts on the edge of the stored wire-shaped light-emitting body 3.

Returning to FIG. 1B, the mounting groove 4 has an axial cross-sectional shape in which the groove bottom 9 is wider than the groove opening 8. As a result, the elasticity retaining effect when the mounting peripheral portion DE is inserted is enhanced, and the problem of falling off and the like can be further reduced. More specifically, in the mounting groove 4, both inner side surface portions 4 a, 4 a facing each other in the groove width direction are formed in a flat shape approaching each other on the groove opening 8 side. When the mounting peripheral portion DE is inserted, the planar inner surface portions 4a, 4a are in close contact with the mounting peripheral portion DE, and the friction holding force can be increased. In this embodiment, the axial cross section of the elastic mounting member 2 has a horseshoe shape following the inner shape of the mounting groove 4.

Next, as shown in FIG. 2, the wire-shaped luminous body 2 covers the periphery of the core-shaped internal electrode 10 with a fluorescent luminous medium 11, and further outside the helical linear external electrode 12. Is wound around the electroluminescent element. The internal electrode 10 and the external electrode 12 are used as drive electrodes, and a light emission drive section 20 of an electroluminescent element is connected to the drive electrodes via a power supply cable 21. The adoption of the electroluminescent element realizes a light emitting unit having low power consumption and high luminous intensity.

The wire-shaped luminous body 2 is configured as an AC EL device, and the fluorescent luminous medium 11 is configured as a flexible material in which a fluorescent material is dispersed in a transparent polymer material. The phosphor is, for example, a yellow-orange ZnS: Mn (a base material is shown before a colon (:), and an activator component is shown after a colon; the same applies hereinafter). A green ZnS: TbF ₃ phosphor or SrS: (Ce, Cl) phosphor, a red spectroscopic system CaS: E u phosphor or ZnS: SmF ₃ phosphor, blue of ZnS: TmF ₃ a phosphor or the like can be used. Here, since the luminous body 2 has a structure in which the fluorescent luminous medium 11 is sandwiched between the electrodes 10 and 12, the luminous body 2 has a specific capacitance (capacitance).

Next, FIG. 3 shows a configuration example of an electric circuit of the light emitting unit 1. A power supply cable is supplied from the battery 27 of the vehicle M (FIG. 4) to a predetermined power supply destination in the vehicle M, in this embodiment, a vehicle-side wiring portion C for supplying power to a door lamp (not shown). 21 and 21 are connected by a connector section 30 attached to the end. The power supply cables 21 and 21 extend into the light emission drive unit 20. Since the alternating current from the alternator 28 mounted on the vehicle M is often superimposed on the direct current from the battery 27, the rectifying diode 22 and the ripple removing And a condenser 23 are provided.

The battery voltage is boosted by the power supply cables 21 and 21 and applied to the wire-shaped light-emitting body 2 configured as an AC-type EL element by the booster circuit 25. A thyristor 26 is provided between the power supply cables 21 and 21, that is, on the short-circuit path 20 a that short-circuits between the two electrode terminals of the wire-shaped light-emitting body 2. A sawtooth wave output is input. The oscillation frequency of the sawtooth wave is set in accordance with the driving frequency (for example, about 400 Hz) of the wire-shaped light-emitting body 2 (EL element).

Hereinafter, the operation of the light emitting unit 1 will be described. First, as shown in FIG. 1, the luminous body unit 1 is attached to the door edge DE, and the power supply cables 21 and 21 are connected to the vehicle side wiring portion C. When the door D is opened as shown in FIG. 4, in the circuit of FIG. 3, the door switch 29 provided on the vehicle-side wiring portion C is turned on, the door lamp is turned on, and the light emitting unit 1 is switched to the power receiving state. Become. The thyristor 26 turns on when the voltage input to the gate terminal exceeds a predetermined trigger voltage due to the sawtooth wave input from the circuit 24, and turns off when the voltage drops below the holding voltage, and turns off the short-circuit path 20a. The EL element 4 opens and closes at the driving frequency. When the thyristor 26 opens the short-circuit path 20a, the wire-shaped light-emitting body 2 is energized in the first direction in which its own capacitance is charged by the output from the booster circuit 25, and conversely. When the short-circuit path 20a is closed, the electric charge accumulated in the capacitance is discharged through the short-circuit path 20a, so that the current is supplied in the opposite second direction. As a result, a saw-tooth AC waveform corresponding to the driving frequency is input to the wire-shaped light-emitting body 2, and as shown in FIG. When the door D is closed, the door switch 29 in FIG. 3 is turned off, and the wire-shaped light emitter 2 is turned off.

The elastic material constituting the elastic mounting member 2 may be colored with a dye in order to suppress the see-through of the wire-shaped light-emitting body 3 inside. In this way, the elastic mounting member 2 hides (or makes it less noticeable) the wire-like light-emitting body 3 during daytime use, etc., and at the same time, exhibits a decorative effect due to the effect of the color of the wire itself, thereby further enhancing the appearance. Can be improved.

The object to which the luminous body unit 1 is attached is not limited to the door edge. For example, as shown in FIG. 4, the object can be attached to the periphery of the license plate NP, and the edge of the radiator tag can also be applied. .
