Abstract
An image projector comprises a liquid crystal display module and a light source both contained in a housing. The housing is formed with an inlet and an outlet, and is provided with a fan. An air flow channel is provided between the inlet and the outlet within the housing. There is provided a wind separator in the air flow channel, which separator separates cooling air such that cooling air flows separately towards the liquid crystal display module and the light source, for better cooling effect.
