1. A display and illumination system comprising: a light source section housing a light source module for producing light;a holder having opposed first and second holder bodies and retaining said light source module in said light source section between said first and second holder bodies;an optical fiber for transmitting the light produced by said light source module;a display illumination unit receiving, through and away from said optical fiber, and radiating the light produced by said light source module, wherein said light source module includes opposed first and second sides transverse to said first and second holder bodies, wherein said second side has a concave surface that has a concave surface axis which is transverse to the first and second holder bodies,a light source disposed within said light source module and between said first and second holder bodies and said first and second sides, wherein said light source has an optical axis along which the light is emitted,a tubular portion projecting from said first side, having a central axis, and engaging said optical fiber so that the optical axis of said light source is aligned with the central axis of said tubular portion,a plug electrode for supplying electrical power to said light source, anda pressing member transverse to said first and second holder bodies, engaging, and rotatable about an axis of rotation that is transverse to said first and second holder bodies, wherein said pressing member has an exterior surface which, in a cross-section transverse to the axis of rotation, varies smoothly in separation from the axis of rotation, for engaging and disengaging said concave surface of said second side and urging said tubular portion toward and away from said optical fiber, with the concave surface axis of said second surface intersecting the optical axis of said light source and the central axis of said tubular portion. 2. The display and illumination system according to claim 1, wherein said plug electrode is a plate-like body having a substantially rectangular shape, with longer sides and shorter sides, when viewed in a plane parallel to said first and second holder bodies, and is located between said tubular portion and said concave surface of said second side so that the longer sides are parallel to a line connecting the central axis of said tubular portion to the concave surface axis of said concave surface. 3. The display and illumination system according to claim 2, comprising a window section, installed opposite said plug electrode of said light source module, for observing whether said light source is emitting light. 4. The display and illumination system according to claim 1, wherein said light source is a laser diode. 5. The display and illumination system according to claim 1, wherein said holder includes pinching means pinching said tubular portion of said light source module in a prescribed position. 6. The display and illumination system according to claim 5, wherein said pinching means comprises a pair of leaf springs pinching said tubular portion of said light source module, andsaid leaf springs include bent portions for aligning said tubular portion in said leaf springs. 7. The display and illumination system according to claim 1, wherein said pressing member has an elliptical cross-section. 8. The display and illumination system according to claim 1, wherein said display illumination unit is installed in a building, andsaid light source section has a switch for turning said display and illumination system on and off, and a switch box installed in the building. 9. The display and illumination system according to claim 1, including a diffuser plate installed in said display illumination unit, wherein said diffuser plate is concave, planar, or partially concavo-convex, depending on an area to be illuminated. 10. The display and illumination system according to claim 1, wherein said light source section is installed at an inlet and an outlet of a tunnel, andsaid display illumination unit is installed in the tunnel, and including a diffuser plate installed in said display illumination unit and a fluorescent substance, generating white light or light of the color of a flame reaction of sodium, on said diffuser plate. 11. The display and illumination system according to claim 1, wherein said light source is installed inside a vehicle,said display illumination unit is installed in the vehicle, and including a diffuser plate installed in said display illumination unit, and a fluorescent substance generating light of a prescribed color corresponding to the location of said display illumination unit, applied to said diffuser plate.
