Summary:PROBLEM TO BE SOLVED: To provide a lighting system that has a wide color temperature range by using three different types of white light-emitting diodes. SOLUTION: A first light-emitting diode 8 is a light-emitting diode that emits white light having a color temperature ranging from 6,500 K to 3,600 K. A second light-emitting diode 10 is a light-emitting diode that emits light of so-called electric-bulb color having a color temperature ranging from 3,600 K to 2,500 K. A third light-emitting diode 12 is a light-emitting diode that emits light of amber color having a color temperature ranging from 2,500 K to 2,100 K. Each light-emitting diode is arranged on a substrate 14 at equal intervals so that the interval becomes L. COPYRIGHT: (C)2008,JPO&INPIT
