Source 121) so that red LED chips 121a and orange LED chip 121b shine simultaneously.Equally, in " brightness attention mode ",
The control circuit for light source 41 for receiving the luminous instruction of the blue wave band light from control unit 38 controls blue-light source device 300
(blue-light source 301), so that blue LED die 301a and purple LED chip 301b shine simultaneously.
The white light generated under " the brightness attention mode " is added to the green band light projected from fluorescence panel assembly 100
Red light of the Calais from the blue light of blue LED die 301a and from red LED chips 121a, also from purple LED core
The purple light of piece 301b and orange-colored light from orange LED chip 121b and generate.Thus, blue wave band light and red band
Light is deviated to short wavelength side respectively, so the white light generated is the white light closer to white (i.e. brightness is high).
In addition, in the setting such as dark interior projection arrangement 10, showing without high brightness but want for film etc.
In the case where keeping the tone of projected image distincter, can by illuminance transducer etc. automatically or by the selection of user come
It selects " color attention mode ".Specifically, receiving in " the color attention mode " as the 2nd mode from control unit
The control circuit for light source 41 of the luminous instruction of 38 red band light controls red light source device 120 (red light source 121), so that
Only red LED chips 121a shines, orange LED chip 121b does not shine.Equally, the blue wave band from control unit 38 is received
Luminous instruction control circuit for light source 41 control blue-light source device 300 (blue-light source 301) so that only blue LED die
301a shines, purple LED chip 301b does not shine.In this way, red light is only projected in red band light, in blue wave band light
Blue light is only projected, so the projected light of more appropriate tone can be obtained.
