TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Component: The light emitting assembly includes a light guide plate (14) mounted adjacent an inner surface of the light transmission section and light sources (15) that irradiate light through a side surface of the light guide plate. The light guide plate is mounted in contact with a rear surface of the light transmission section or in separation from the inner surface of the light transmission section at a predetermined distance. When the light guide plate is mounted in separation from the inner surface of the light transmission section at a predetermined distance, a transparent material is filled in the distance between the light guide plate and the inner surface of the light transmission section. The light guide plate includes a light reflecting assembly parallel to the light transmission section and realized through a surface of the light guide plate farthest from the light transmission section, and a light scattering assembly parallel to the light transmission section and realized through a surface of the light guide plate closest to the light transmission section. The light reflecting assembly as realized through protrusions (20), a mirror sheet, or a metal film. The light scattering assembly is a light scattering sheet, with protrusions and depressions formed by a sunblast process. A diachronic mirror is coated on a surface of the light guide plate farthest from the light transmission section and parallel to the light transmission section, the diachronic mirror selectively reflecting light of a specific wavelength. The lighting sources are light-emitting apparatus including light bulb and light-emitting diodes.    TECHNOLOGY FOCUS - POLYMERS - Preferred Material: The transparent material is ethylene vinyl acetate. The light guide plate is made of a transparent material comprising polycarbonate, ethylene vinyl acetate, or acrylic resin including polymethyl methacrylate. The case is made of glass, or polycarbonate.
