Abstract
The compact lamp consists of a light source, a focusing lens, a specially shaped secondary lens with a saddle-shaped output surface, a light transmitting element, a battery holding chamber with an electrical control circuit connected to a button for control of the lamp source via a magnetic contact. Some of these elements are placed inside the lamp housing, mounted on an end of a handlebar or another suitable lighting device, and some other elements, including the battery and the magnetic control circuit, are installed inside the handlebar tube or the housing of the lighting device. The compact optical layout enables a beam, which is sharply limited in the vertical plane and sufficiently wide in the horizontal plane and is suitable for daytime running lamps, night headlamps or position lights. When at least two light sources are used in one lamp, beams of different light dispersion patterns can be electrically toggled.
