ABSTRACT:
The invention relates to an improvement in light fixtures of the type having a base, a socket receiving a bulb, and a primary reflector defined on the base located in relatively close proximity to the bulb. The improvement consists of a secondary reflector located between the primary reflector and the bulb. The secondary reflector is closely spaced from the primary reflector defining an air gap therebetween. The secondary reflector provides dispersion of concentrated heat produced by the bulb to maintain the primary reflector at a lower temperature whereby the air gap reduces heat transfer between the reflectors, and the secondary reflector is formed of a reflective material to provide improved light reflectance qualities.
