A light-emitting apparatus includes: a flexible base body; and a light-emitting component which is attached to the base body, has a form which changes flexibly following a change in the firm of the base body, and includes: a light guide which guides laser light that enters one end of the light guide; a leaking means for causing part of the laser light guided by the light guide to leak out of the light guide in a direction which crosses a light-guiding direction; and a first light-emitter which extends along the light-guiding direction and emits light based on the part of the laser light that is leaked out of the light guide by the leaking means.

A motor and pumping system which provides for high volume, low pressure, low cost, and ease of assembly as a breathing air supply such as for a submerged diver. The integration of the necessary elements gives rise to a unique ability to eliminate costly and complex motor bearings and simplify the motor design by reducing number of magnetic poles and electrical control elements which would traditionally be required to control the multiple poles of an electromechanical machine.
