The decorative cover 8 is made of resin or metal, and has a cover body 15 extending substantially along the upper edge 6 of the radiator grille 3 and having a substantially rectangular shape in a side view. An insertion portion 18 that can be inserted into an overshoot gap 17 of about 8 mm formed between the radiator grill 3 and the bonnet 16 is formed so as to protrude from both ends and the center of the cover body 15. Screw holes 1 for screwing the upper edge 6 of the radiator grill 3 to the portion 18
9 are formed.

The ultraviolet light source 9 comprises a rod-shaped cold cathode tube 21 as shown in FIG. 5 or a hot cathode tube 22 as shown in FIG. As the cold cathode tube 21, for example, a tube having a diameter of 3 to 5φ and a frequency of 250 kHz to 40 kHz is used. Further, as the hot cathode tube 22, for example, 5
Use a frequency of 0 Hz. The two ultraviolet light sources 9 are arranged in series according to the length of the upper edge 6 of the radiator grill 3.

The bracket 10 is made of an elastic material, silicon rubber, a vibration absorbing material, or the like, and has a shape capable of externally holding both ends of each ultraviolet light source 9. Then, a bracket 10 holding each ultraviolet light source 9 is brought into contact with the back surface of the decorative cover 8, the bracket 10 is pressed by the band member 23 from the back surface side of the decorative cover 8, and both ends of the band member 23 are Each of the ultraviolet light sources 9 is fixed to the decorative cover 8 via the bracket 10 by fixing the ultraviolet light source 9 to the boss portion 24 formed on the rear surface of the light emitting device with the screw 25.

The protective cover 11 is made of a transparent resin (for example, ABS resin) or a glass of an ultraviolet transmitting type which does not contain an ultraviolet absorbing material.
It has a substantially rectangular shape extending in a side view. And
By attaching the protective cover 11 to the back surface of the cover body 15 so as to cover the ultraviolet light source 9, two ultraviolet light sources 9 arranged in series can be accommodated and sealed. The protective cover 11 is attached to the cover body 15 by screws or heat welding (not shown). Cover body 15
A waterproof seal 26 is provided in a gap 17 between the cover 11 and the protective cover 11.

The inverter device 12 is a vehicle 12
It has a function of boosting the voltage of V to 100V or 110V. The inverter device 12 is mounted at an appropriate position in the engine room.

Furthermore, an ultraviolet light emitting device 5
The phosphor layer 31 which emits light by the ultraviolet rays from the substrate is formed. As shown in FIG. 7, a transparent resin binder for improving adhesion is added to a fluorescent paint made of an inorganic pigment having high permanent durability or an organic pigment having high transparency, as shown in FIG. Shall be. The phosphor layer 31 is further covered with a transparent resin 32. The exterior component 4 has, on the surface of a base material 33 such as an ABS resin, a layer 36 obtained by adding an aluminum leaf 35 for giving a metallic feeling to the transparent resin 34, and a layer 37 of the transparent resin alone. .

Next, the operation of the first embodiment will be described.

In the first embodiment, the phosphor layer 31 is formed on the exterior component 4 such as the radiator grill 3 serving as a base, and the ultraviolet light emitting device 5 is attached to the exterior component 4.

Then, when the ultraviolet light emitting device 5 is turned on, the exterior component 4 having the phosphor layer 31 formed on the surface thereof is illuminated by the ultraviolet light from the ultraviolet light emitting device 5, and a high decorative effect can be obtained.

Since the ultraviolet light emitting device 5 can be easily retrofitted to the exterior component 4, the decoration effect of the exterior component 4 can be easily enhanced.

More specifically, in the ultraviolet light emitting device 5, the insertion portions 18 protruding from both ends and the center of the cover main body 15 are screwed to the upper edge portion 6 of the radiator grill 3, and the radiator grill 3 and the The cover body 1 is removed from an overshoot gap 17 formed between the cover body 1 and the bonnet 16.
Attach so that 5 comes out. By doing this,
The mounting can be performed without interfering with the hood 16 or the like and without adversely affecting the appearance.

In the ultraviolet light emitting device 5, since the ultraviolet light source 9 is protected by the transparent and transparent protective cover 11, it is resistant to external impact and is provided in the gap 17 between the cover body 15 and the protective cover 11. With the waterproof seal 26 provided, high water resistance can be obtained.
