Projection device and light engine module

A projection device, comprising:

• a light source module, adapted to provide an illumination beam, wherein the illumination beam comprises a first wavelength range and a second wavelength range;
• a light engine module, comprising:
• a first dichroic element, disposed on a transmission path of the illumination beam and used for dividing the illumination beam into a first color beam and a second color beam, wherein the first color beam comprises the first wavelength range, the second color beam comprises the second wavelength range, the first wavelength range of the illumination beam passes through the first dichroic element to form the first color beam, and the second wavelength range of the illumination beam is reflected by the first dichroic element to form the second color beam;
• a first light valve, disposed on a transmission path of the first color beam and used for converting the first color beam into a first image beam;
• a second light valve, disposed on a transmission path of the second color beam and used for converting the second color beam into a second image beam;
• a light combining element, disposed on transmission paths of the first image beam from the first light valve and the second image beam from the second light valve;
• a first light converging element, disposed between the first light valve and the light combining element;
• a second light converging element, disposed between the second light valve and the light combining element;
• a first light guiding element, disposed among the first dichroic element, the first light valve and the light combining element, and used for guiding the first color beam to the first light valve;
• and
• a second light guiding element, disposed among the first dichroic element, the second light valve and the light combining element, and used for guiding the second color beam to the second light valve;
• and
• a projection lens, disposed on a transmission path of the first image beam and the second image beam from the light combining element, wherein the light combining element is disposed among the projection lens, the first light valve and the second light valve, the light combining element is disposed among the projection lens, the first light converging element and the second light converging element, and the light combining element is disposed among the projection lens, the first light guiding element and the second light guiding element.
