<P>PROBLEM TO BE SOLVED: To provide a multipurpose light emitting apparatus emitting light of various color tone using a fiber illuminant cable, to provide use of hot air, and to provide an effective plant cultivating method. <P>SOLUTION: This light emitting apparatus has a light source part and also a fiber illuminant cable which is composed of a cladding layer covering a core and its perimeter and has a fixed length. A plurality of high power LED light emitting diodes having different light colors in the light source are facingly attached to the end surface of the fiber illuminant cable, thus light emission is actually performed from the perimeter of the fiber illuminant cable. As a result of this, the light emitting apparatus can remarkably improve durability and besides, is excellent in drip-proofing, and color rendering because of being free from a problem of color phase separation like a case using a plurality of known light colors, and facilitates change of luminescent color, and enables multi-function and versatility. Light emission, especially optical illumination of a red-based color, from the fiber illuminant cable which is composed of a cladding layer covering a core and its perimeter and has a fixed length, is suitable for effective plant cultivation. <P>COPYRIGHT: (C)2008,JPO&INPIT |
