Abstract: A number plate including luminous characters is usually mounted below head lamps of a vehicle. As essential components, this number plate includes a front plate having a plurality of character portions punched therefrom, a plurality of characters each molded of a transparent or translucent synthetic resin and adhesively fitted into the character portions, a plurality of light emitting diode assemblies arranged on the rear surface side of the front plate at the positions located corresponding to the character portions, a cover secured to the rear surface of the front plate and having the light emitting diode assemblies accommodated therein, and a plurality of base boards having the light emitting diode assemblies arranged at the positions located corresponding to the character portions. In addition, the cover includes a support member for supporting the base boards which are connected to each other in the side-by-side relationship.

Abstract: A number plate including luminous characters is usually mounted below head lamps of a vehicle. As essential components, this number plate includes a front plate having a plurality of character portions punched therefrom a plurality of characters each molded of a transparent or translucent synthetic resin and adhesively fitted into the character portions, a plurality of electroluminescent plates disposed on the rear surface side of the front plate so as to illuminate the character portions, a DC/AC inverter disposed on the bottom side of a case of the number plate and electrically connected to the electroluminescent plate and a power source, a plurality of base boards each fitted to an electroluminescent plate and having the substantially same area as that of each character portion, and a support portion for supporting the base boards thereon.

Abstract: A vehicular number plate including luminous characters of the type comprising a number plate having a plurality of chracter portions punched therefrom to which a plate molded of a transparent or translucent synthetic resin is adhesively secured and illuminating bulbs for illuminating the character portions, wherein a light scattering plate having a number of quadrangular pyramid-shaped light scattering projections formed thereon is interposed between the number plate and the illuminating bulbs in an area corresponding to positions where the illuminating bulbs are disposed. Each of the quadrangular pyramid-shaped projections has an apex angle which is determined in the range of 90.degree. to 160.degree.. The illuminating bulbs may be replaced with a single fluorescent lamp. In this case, the light scatteering plate includes a receiving portion in which the fluorescent lamp is received and a light scattering portion extending from the receiving portion while having a gradually reduced thickness.
