摘要： An illumination device is provided of the type arranged at the front which is of low power consumption and of high recognisability both when the illumination is turned on and when illumination is turned off. An illumination device arranged at the front face of an illuminated object has a light-guide plate forming a transparent flat plate shape and formed with point-form optical extraction structures on its surface or in a position facing this surface, and a light source arranged opposite and end face of this light-guide plate. The light source is for example a point light source. The optical extraction structures are for example pillar-shaped projections and these are arranged two-dimensionally. The function is provided that, when this illumination device is arranged at the front of the illuminated body, rays are projected on to the illuminated body and rays reflected by the illuminated body are transmitted with scarcely any dispersion. There is also provided a function of transmitting external light with scarcely any dispersion of rays reflected by the illuminated body when the illumination is not turned on. A point light source such as a light emitting diode (LED) or electric light bulb can be employed and low power consumption can easily be achieved.

摘要： A reflection layer is provided on a surface of a light guiding body on which projections are formed with intervals, except the side surfaces of the projections. A light emitting element is provided close to one end surface of a light guiding element. Most of the light from the light emitting element is input to the light guiding body through the light input surface. The light travels through the light guiding body to be output from the side surfaces of the projections. After passing through a directional change element, the light is input to the light receiving element in a direction substantially perpendicular to a light receiving element. Outside light passes through the light receiving element and is then input to a lighting apparatus. In the lighting apparatus, the outside light passes through the directional change element to be reflected by a reflection layer on the light-output-side surface of the light guiding body and then again passes perpendicularly through the directional change element toward the light receiving element. When the light passes through the light receiving element, a displayed image can be viewed. The reflection layer can reflect the light with a small loss. In addition, if the outside light is input at an angle of other than 90.degree. to the light receiving element at first, the light can be reflected by the reflection layer with a small loss.

摘要： The invention provides a linear organic electroluminescent light source which is high in brightness and capable of realizing white color. A brighter light source can be obtained compared with a light source having only one organic electroluminescent element by forming the organic electroluminescent element to have at least one organic layer, which emits light, on both sides of a transparent substrate, and covering the transparent substrate with a mirror which is high in reflectance except one end face of the transparent substrate. When the same brightness as that of a light source having one element is obtained, the power consumption can be suppressed. The light source can thus emit white light.
