  • Publication number: 20100002452
    Abstract: A luminaire housing with a lamp compartment and ballast compartment that are isolated from each other is provided. The housing includes a lamp compartment, a ballast compartment, and an air gap chamber separating the two compartments from each other. The air gap chamber provides a degree of thermal isolation that reduces the amount of heat generated by the lamps that is transferred from the lamp compartment to the ballast compartment. The luminaire can also include a ventilated top cover and a bottom door configured to attach to the lamp compartment while leaving an air gap therebetween. These and other optional features improve the air circulation within the lamp compartment and allow heat generated by the lamps to exit the luminaire housing, further reducing the heat transferred to the ballast compartment, thereby improving the lifespan and performance of the ballasts.
