    摘要: A red-reflecting film and a blue-reflecting film are formed in a substantially X shape on joint surfaces defined by the respective side faces of four columnar prisms or right-angle prisms. The red-reflecting film is continuously formed without separating at an intersection of the two reflecting films. The blue-reflecting film is, on the other hand, divided into two pieces by the red-reflecting film and an adhesive. It is preferable that that four columnar prisms are obtained from one block of sheet glass. This arrangement ensures an improvement in properties of a resulting light-selective prism.

The light-emitting tube has a light-emitting section having the discharge space therein and sealing sections provided on both sides of the light-emitting section. The sub-reflection mirror is formed in a shape of a bowl that covers the light-emitting section of the light-emitting tube, the sub-reflection mirror having an opening for mounting the sub-reflection mirror to the light-emitting tube by allowing one of the sealing sections of the light-emitting tube to be inserted thereinto. A heat insulating member is provided to at least a part of the light-emitting section and the other one of the sealing sections of the light-emitting tube.
