<P>PROBLEM TO BE SOLVED: To configure a lighting system without decreasing a light use efficiency. <P>SOLUTION: This lighting system includes: a first parabolic reflector that guides incident light parallel to a first optical axis to a focal point and guides the incident light from the focal point in a direction parallel to the first optical axis; a light source irradiating the first parabolic reflector with a first reference light; a wavelength conversion element that has a transmission body for transmitting the first reference light, and a light-emitting body emitting a second reference light with the first reference light used as an exciting light and guiding it to the first parabolic reflector; a second parabolic reflector guiding the incident light in a direction parallel to a second optical axis crossing with the first optical axis; and an optical member that is provided at a position where the first optical axis and the second optical axis cross each other and substantially matches a light path of the second reference light reflected by the first parabolic reflector with a light path of the first reference light reflected by the second parabolic reflector. <P>COPYRIGHT: (C)2012,JPO&INPIT |
