Disclosed is a luminous door device using a light guide panel. A desired letter or pattern is formed as micro depressions on one surface of a light guide panel made of a transparent acrylic plate material. A light source section is disposed in one lateral side or both facing lateral sides of the light guide panel so as to abut a lamp such that the light of the lamp is incident inwards of the light guide panel. The light source section is composed of one or plural light source modules linearly connected. The light source module includes at least one lamp and a lamp drive section for supplying power to the lamp, which are mounted in a lamp housing to form a single module. A combination set of the light guide panel and the light source section closely disposed to the lateral side thereof is mounted and fixed to a door frame. The lamp light incident inside the light guide panel is totally reflected on a region not having a depression and scattered or diffusion- reflected on a region having the depression of desired pattern such that the latter region of the desired pattern shines more brightly than the former region. |
