Video projector system

A video projector system comprising:

• a plurality of light engine modules, each light engine module configured to provide light within one or more spectral bandwidths, each light engine module comprising:
• a light engine housing;
• one or more light sources configured to emit light within at least a portion of one of the spectral bandwidths, the one or more light sources housed within the light engine housing;
• and
• a cooling system configured to reduce an operating temperature of the light engine module;
• and
• a light guide configured to receive light from the light engine modules and to deliver the received light to an optical engine.

A light engine module for use in a modular video projector system, the light engine module comprising:

• a light engine housing;
• one or more light sources housed within the light engine housing, the one or more of light sources configured to produce light having one or more central wavelengths and one or more spectral bandwidths;
• an optical output configured to connect with a fiber optic cable;
• an optical system configured to direct the light provided by the one or more light sources onto the optical output;
• a cooling system configured to reduce an operating temperature of the one or more light sources, the cooling system housed within the light engine housing,
• wherein incorporation of the light engine module into a modular video projector system allows the light produced by the light engine module and output via the optical output to be combinable with light produced by one or more other light engine modules also incorporated into the modular video projector system to provide a scalable light source.
