ABSTRACT:
The invention provides a light source and a projector with sufficiently high luminance and size reduction for related art lamps, an increased lamp lifetime, and reduced noises from a cooling fan. A light source includes a concave mirror which has a reflecting part that reflects light, non-reflecting parts adjacent to this reflecting part, and permeable ports that pass through the non-reflecting parts, and which opens forward; a lamp which is arranged in this concave mirror and emits the light; and a light permeable member which covers the opening part of the concave mirror. The concave mirror includes a mesh arranged in a position where it covers the permeable port, and a protective wall to protect the mesh, which is arranged in a position where direct collision between the mesh and broken pieces of the lamp made by a burst of the lamp is reduced or prevented.
