<P>PROBLEM TO BE SOLVED: To provide a light-emitting device capable of requiring no time for changing formation of a lens-shaped section in case that changes of light-distributing characteristics are required and being adjusted to an arbitrary beam light-distributing angle. <P>SOLUTION: The light-emitting device 1 has a light-emitting tube 2, a base member 3, a glass globe 4, a reflecting plate 5, a light-deflecting member 6, and a telescoping mechanism 7. The base member 3 is mounted on a base section 8 of the light-emitting tube 2, and supplies electric energy to the light-emitting tube 2. The glass globe 4 is arranged by connecting with the base member 3, and functions as a housing member for housing the light-emitting tube 2 in an internal space 9. The reflecting plate 5 is arranged on the surface for preparing the internal space 9, and reflects light of the light-emitting tube 2. The light-deflecting member 6 deflects the light emitted from the light-emitting tube 2 and reflected by the reflecting plate 5, or the light emitted from the light-emitting tube 2 and directly incident to the reflecting plate 5 in a converging or diffusing direction. The telescoping mechanism 7 is arranged on the base section 8 of the light-emitting tube 2, and can expand and contract the glass globe 4 in the light emitting direction or in the opposite direction. <P>COPYRIGHT: (C)2010,JPO&INPIT |
