HIGH INTENSITY BALLAST ASSEMBLY

摘要

Case 2748 HIGH INTENSITY BALLAST ASSEMBLY This invention relates to a weatherproof ballast housing assembly for the containment of electrical ballast components associated with the operation of gaseous discharge lamps and especially those used in outdoor lighting applications or indoor applications where wash down of the ballast housing and luminaire is involved. In the preferred embodiment the ballast housing assembly includes a first housing member having a radially offset flange portion, a second housing member having a rim portion, and a plate member overlaying the rim face of the first housing member and having a depending skirt portion which plate member is adapted for the mounting of a transformer and a capacitor on opposing surfaces thereof. The radially offset flange portion co-acts with a predetermined length of the rim portion over a co-acting region to align in sandwiched relation therebetween the depending skirt portion. Screws are provided across the co-acting region to secure the first housing member, the second housing member and the plate member in a mutually fixed, weatherproof relation. The instant ballast housing assembly provides for reduced manufacturing costs, ease of maintenance and a degree of weatherproofing which in combination were not previously provided.
