  • Light generation device for projector
    Patent number: 7717588
    Abstract: The light generation device contains a bowl-shaped reflection member for light focusing, a gas-discharge light bulb inside the reflection member, and a lens element positioned on the light bulb blocking the light beams emitted towards a front opening of the reflection member. In one embodiment, the lens element has a curved front surface so that incident light beams are refracted and redirected toward a focus point of the reflection member. In another embodiment, the lens element has a curved back surface of a specific curvature so that light beams traveling towards the lens element are reflected and redirected towards the reflection member which in turn are reflected again and focused by the reflection member.
