Projector having light emission devices

摘要

An aspect of the present embodiment, there is provided a projector, including a first optical source fixed on a first mount substrate, the first optical source emitting a first light, a second optical source fixed on the first mount substrate being apart from the first optical source for a first distance, the second optical source emitting a second light, a third optical source fixed on a second mount substrate, the third optical source emitting a third light, an emission period of the third light being set between an emission period of the first light and an emission period of the second light.

主权项

1. A projector, comprising:
a first optical source fixed on a first mount substrate, the first optical source emitting a first light with first color; a second optical source fixed on the first mount substrate being apart from the first optical source for a first distance, the second optical source emitting a second light with second color; a third optical source fixed on a second mount substrate, the third optical source emitting a third light with a third color, an emission period of the third light being set between an emission period of the first light and an emission period of the second light; a space optical modulation unit modulating the first light, the second light and the third light, and outputting modulated light as an image; a first optical system introducing the first light, the second light and the third light into the space optical modulation unit; and a second optical system projecting the image, wherein both the emission periods of the first light and the second light are set immediately before or immediately after the emission period of the third light, all of the first light, the second light and the third light emit in one cycle, and each of the emission periods of the first light and the second light is one time and the emission periods of the third light is two times in the cycle, one of the third lights having a longer emission period in the two emission periods is emitted after an emission having a larger exothermic amount in the first light and the second light is performed.
