    • A PAR lamp (10) has a body (12) with an internal reflector surface (14) disposed about a longitudinal axis (16). A cavity (18) is provided at one end (20) of the body (12) and an arc discharge tube (22) that provides a substantially spherical light source is positioned in the cavity (18) and disposed on the longitudinal axis (16). A cover receiving opening (24) is provided at a second end (26) of the body and a cover (27) closes the cover receiving opening (24). A plurality of spiral facets (28) is formed on the internal reflector surface (14), the plurality of spiral facets (28) 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.
    • PAR灯(10)具有主体(12),其具有围绕纵向轴线(16)设置的内部反射器表面(14)。 空腔(18)设置在主体(12)的一端(20)处,并且提供基本上球形的光源的电弧放电管(22)定位在空腔(18)中并且设置在纵向轴线(16)上 )。 在本体的第二端(26)处设置盖接收开口(24),盖(27)封闭盖接收开口(24)。 多个螺旋小面(28)形成在内部反射器表面(14)上,多个螺旋面(28)的数量足以增加最大光束烛光功率,并且与具有 较少数量的方面。 面的数量等于或大于75,优选为100。
