  • Patent number: 6168293
    Abstract: A reflector lamp (10) has a forward parabolic section (58) and a rear concave section (60), which may be parabolic, ellipsoidal, or spherical. A light source (24), such as the filament of a halogen lamp, is axially aligned with the axis of the reflector (LA) and is centered at the focal point of the forward and rear sections. The parabolic forward section is fluted to spread the light reflected therefrom smoothly in a beam of light, minimizing the center hot spot. The rear section, which is not fluted, directs the light reflected therefrom within the desired beam angle, resulting in little wasted light being emitted outside the desired beam angle.
