Abstract (en)
[origin: US5729079A] PCT No. PCT/DE94/00464 Sec. 371 Date Oct. 23, 1995 Sec. 102(e) Date Oct. 23, 1995 PCT Filed Apr. 27, 1994 PCT Pub. No. WO94/25978 PCT Pub. Date Nov. 10, 1994The invention relates to a compact fluorescent light bulb in the form of a reflector lamp. The discharge vessel (3) of the light bulb according to the invention preferably comprises a plurality of U-shaped glass tubes (30, 31), which are located in the same plane at right angles to the reflector axis. As a result, on the one hand a short structural length is attained, which is only insignificantly greater than that of a commercially available general-purpose incandescent bulb, and on the other, the reflector lamp of the invention, when used in ceilings or chandeliers, has a horizontal lighting intensity that is increased by the factor of 4 over a conventional compact fluorescent light bulb.
