  • Lamps having multiple and aimed parabolic sections for increased useful light output
    Patent number: 4494176
    Abstract: A reflector lamp having multiple and aimed parabolic reflective sections so as to improve the desired beam pattern is disclosed. The reflector lamp may be of the parabolic aluminized reflector (PAR) or the reflector (R) type lamps having primary, multiple intermediate and rear sections of a parabolic contour which improves the internal light reflective and absorption characteristics of the reflector lamp. The overall effect is to improve the optical efficacy of the reflector lamp.

  • Sealed beam lamp unit
    Patent number: 4425606
    Abstract: An adhesively sealed beam lamp unit including a lens and reflector having cooperating and opposing step-shaped sealing surfaces located approximately about the lens and reflector peripheries. Contact between the lens and reflector sealing surfaces is limited to one or more portions along the innermost pair of opposing steps. Additionally, reservoirs, located on either side of the sealing surfaces, restrict excess adhesive from spreading onto areas affecting lamp unit optical performance or outer dimensions.
