Abstract
A portable headlamp that is particularly designed for use with bicycles integrates a number of essential features and functions desired by modem bicyclists. The headlamp has an easily removable and universally mountable fastening system that requires no tools to install. The mounting system includes a rotary joint that enables a headlamp to be pointed in any desired direction while maintaining a constant friction that can be set by the user. A focussable light beam enables the operator to vary the light distribution pattern, thereby making the headlamp suitable for use under a number of different conditions. The electrical system for the headlamp can be readily upgraded to accommodate the needs of different riding conditions, without requiring additional parts. All of these features are contained within a compact, streamlined housing that is designed to accommodate batteries in a manner that maintains the center of gravity of the headlamp coincident with its mounting point, thereby increasing its stability under rough riding conditions.
