Abstract: A lighting apparatus having a light emitting unit separable from a battery case can be used conveniently for a bicycle. The light emitting unit incorporates a light bulb capable of being lighted on with an electric current supplied from the battery case through a power supply cable. Since the light emitting unit is separated from the battery case, it can be made compact and easily mounted on the handlebar of the bicycle independent of the battery case. Consequently, the light emitting unit is not a hindrance to a bicycle rider in handling the bicycle, and it is hard to experience a shock and be damaged in riding the bicycle. By demounting the light emitting unit and battery case from the bicycle and uniting them directly to each other, the lighting apparatus can be used as a portable flashlight.

Abstract: In a lighting device in which planar light is emitted from the planar light emitting surface of a light guide by using a point-source light, such as an LED, the emitted light having a uniform luminance level is obtained on the overall light emitting surface. The lighting device has a point-source light 18 for emitting light in a point-like form. A planar light guide 16 radiates light in a planar form from the planar light emitting surface 16a. A linear light guide 19 is disposed between the point-source light 18 and the planar light guide 16. The point-like light emitted from the point-source light 18 is converted into linear light by the linear light guide 19, and the linear light is guided into the planar light guide 16 through the light incident surface 16b. Since the linear light is incident on the planar light guide 16, the light having a uniform luminance level can be obtained on the overall light emitting surface 16a.
