摘要： A current of the same amount or in a constant ratio is applied to each of a combination of a blue light emitting diode having a small wavelength variation and a green light emitting diode having a large wavelength variation. With this, as an amount of applied current increases, an oscillation wavelength of the green light emitting diode having the large wavelength variation changes from a long wavelength side to a short wavelength side and mixes with a blue color of the blue light emitting diode having the small wavelength variation to gradually change chromaticity as a whole. When desired chromaticity is obtained, the amount of the current is fixed.

摘要： There is provided a method that allows fabrication, through a simple process, of a good quality semiconductor light emitting device having a semiconductor light emitting element surrounded and thus covered with a fluorescent layer formed of resin uniform in thickness. At least two semiconductor light emitting elements are bonded to a substrate with a predetermined interval. Subsequently a first resin serving as a fluorescent layer is molded across the entire surface of the substrate substantially parallel to the top surface of the semiconductor light emitting element to cover the semiconductor light emitting element. After the first resin is cured, the first resin is at least partially diced.

摘要： A first light emitting diode and a second light emitting diode are connected in parallel between a first node and a second node. The two light emitting diodes are connected to each other in such a manner that, an anode of each one light emitting diode is electrically connected to a cathode of the other light emitting diode. As a driving portion applies an AC voltage to each of the two light emitting diodes, a light emitting apparatus can alternately emit light of two colors (blue and green) and light of one color (red). Therefore, since white light can be generated with one driving circuit, size and cost reductions of a light emitting apparatus can be attained. As a result, a light emitting apparatus which is small and capable of easy adjustment of chromaticity can be provided.
