| Zusammenfassung: | A PAR lamp has a body with an internal reflector surface disposed about a longitudinal axis. A cavity is provided at one end of the body and an arc discharge tube that provides a substantially spherical light source is positioned in the cavity and disposed on the longitudinal axis. A cover receiving opening is provided at a second end of the body and a cover closes the cover receiving opening. A plurality of spiral facets is formed on the internal reflector surface, the plurality of spiral facets being sufficient in number to increase the maximum beam candle power and decrease the beam angle when compared to faceted lamps having a lesser number of facets. The number of facets is equal to or greater than 75 and preferably is 100. |
