  • Glare reducing visor for existing PAR bulb exterior lighting fixtures
    Patent number: 6497501
    Abstract: A PAR bulb visor includes an accessory visor with a plurality of spaced apart spring clips which is adapted to removably attach to the lip of a PAR bulb. The visor is retrofittable to virtually any existing PAR bulb fixture where the lip of the bulb is exposed. The visor is inexpensive to manufacture. It does not require casting and can be made from inexpensive sheet metal. Since the visor can be easily installed and removed from the lip of an existing PAR bulb, it does not interfere with the installation/replacement of the bulb.
