摘要： In a light source device, that obtains high light usage efficiency by projecting simultaneously two or more of three primary color lights X, Y and Z. Moreover, each color light X, Y and Z is divided into two in terms of time so that p-wave and s-wave linear polarization lights are formed, such that the synthesized light of the p-wave linear polarization lights enters a first spatial modulation element and the synthesized light of the s-wave linear polarization lights enters a second spatial modulation element to permit gradation control of each color light.

摘要： A short arc lamp which has a lamp body in which a concave space is formed, a base plate which is located in a rear part of this body, a transparent part which is located in a front opening of the lamp body, with a frame part in its vicinity, and which hermetically encloses the concave space, and a pair of electrodes forming an arc gap in the concave space. The frame part is connected to a circular conductive ring which is provided with the roughly square cross section and is connected to the lamp body. At least a front side of the circular conductive ring is exposed to the ambient environment. A gap is formed between the frame part and the circular conductive ring. The frame part extends more to the front than the circular conductive ring, and on the exposed surface of the circular conductive ring and on a side of the projecting part of the frame part, step-like projections are formed.
