Illumination system and projection device

A projection device, configured to generate an image beam and comprising:

• a illumination system, configured to generate an illuminating light beam and comprising:
• a first light source module, configured to generate a first color light beam, a second color light beam, and a third color light beam;
• a second light source module, configured to generate a fourth color light beam, a fifth color light beam, and a sixth color light beam;
• a first light guide module, disposed on a transmission path of the first to the sixth color light beams;
• a second light guide module, disposed on the transmission path of the first to the sixth color light beams, wherein the first light guide module is configured to transmit the first to the sixth color light beams from the first light source module and the second light source module to the second light guide module;
• a condenser lens module, disposed on the transmission path of the first to the sixth color light beams, wherein the second light guide module is configured to transmit the first to the sixth light beams from the first light guide module to the condenser lens module;
• and
• a light homogenizing element, disposed on the transmission path of the first to the sixth color light beams, wherein the condenser lens module is configured to transmit the first to the sixth color light beams from the condenser lens module to the light homogenizing element, and the first to the sixth color light beams form the illuminating light beam after leaving the light homogenizing element,
• wherein the second light guide module is further configured to separate the first to the sixth color light beams respectively into a first sub-beam and a second sub-beam, so that an aspect ratio of a light spot formed by the first sub-beams and the second sub-beams of the first to the sixth color light beams incident on a light incident surface of the condenser lens module falls within a range of 1 to 1.5;
• a light valve, disposed on the transmission path of the illuminating light beam to convert the illuminating light beam into the image beam;
• and
• a projection lens, disposed on the transmission path of the image beam and configured to project the image beam out of the projection device.
