PROBLEM TO BE SOLVED: To obtain a light emitting diode lamp emitting light of color different from red, green, blue, and the like, of an ordinary light emitting diode chip. SOLUTION: The mixed color diode lamp 1 employs a monochromatic chip 2 as light source and the monochromatic chip 2 is partially coated with a wavelength converting substance 5. Consequently, a mixed color diode lamp 1 emitting light of commercially unanvailable color can be provided using a single light emitting diode chip 2 while minimizing cost increase by limiting increase in the labor required for obtaining the mixed color diode lamp 1 to only one process for coating the wavelength converting substance 5. |
