Here, the light guide plate 1 is coupled to a reflective sheet 3 to reflect the light received therein to one side (lower surface of the drawing) to the emission surface side.

The light source is mainly applied as a CCFL (cold cathode fluorescent lamp) or an EEFL (external electrode fluorescent lamp), and in recent years, a configuration that is applied as an LED (light emitting diode) in order to reduce fast response characteristics and power consumption than a fluorescent lamp is proposed. do.

As described above, the light guide plate 1 may be implemented in a room, interior and exterior interior lighting, etc. as described above, but this configuration is further miniaturized and is widely applied to LCD backlights such as mobile phones and monitors.

According to the structure of the conventional light guide plate illumination device, the light guide plate emits light of a single color as a single light source is provided. As a result, the light guide plate lighting device as described above is difficult to produce a variety of colors of illumination, which results in a problem that can not satisfy a variety of color tastes of the consumer.

In addition, since the light guide plate forming the surface light source in the light guide plate lighting apparatus as described above has not escaped from the conventional concept of a rectangular plate shape, only the simple lighting function is performed to satisfy various color tastes of the above-described consumers. This is further weighted.

The present invention has been devised to solve the above problems, and the purpose of the present invention is to provide a light guide plate lighting device that can obtain a more diverse, excellent decorative effect by emitting light of various colors from a single light guide plate of the light guide plate lighting device. have.
