ILLUMINATOR AND LIGHT SOURCE |
摘要 |
A light source (30) for producing a directable beam of light comprises a frame (32), a lamp (50,52) positioned within the frame (32) which produces light on a light path on which dichroic filters (58-64) are positioned. The dichroic filters (58-64) are pivotally mounted so that the angle of incidence of the light on the dichroic filters (58-64) can be varied to alter the colour of the light. Integrating means in the form of a lens (100) is provided for homogenizing the light passing through the dichroic filters (58-64) to produce a uniform colour. |
