Abstract

This invention provides a light device which can solve the problem of incandescent bulb, cathod ray tube, LED, organic EL etc.. In the case of serving as a light source, the light device is compact and freedom of shape is also high. Besides, there is no such problems as UV or electromagnetic wave generation problem, or such environment contaminative substance as mercury in the light device, and it is easy to produce. Furthermore, the problem of water decomposition resulted from moisture absorption will not happen, and it is easy to manufacture with a simple structure. This invention relates to a light device in which the light source is, for example, a point source, and the point source is a structure with the conductor being clamed by inorganic EL light emitter.
