<P>PROBLEM TO BE SOLVED: To provide a lighting device capable of using a solid-state light-emitting element in various applications without using a discharge lamp, and an image display device having the lighting device. <P>SOLUTION: The lighting device 1 includes an excitation light source 11, a phosphor 32, and a driving section 14. The excitation light source 11 emits excitation light L having a first wavelength. The phosphor 32 emits light having a second wavelength longer than the first wavelength, when the excitation light L is irradiated, and transmits a part of the excitation light L, and emits by multiplexing the transmitted excitation light L and the light having the second wavelength. Then, the driving section 14 moves an irradiation position of the excitation light L of the phosphor 32 with the passage of time. <P>COPYRIGHT: (C)2012,JPO&INPIT |
