Fluorescent lamp assemblies

摘要: Fluorescent lamp assembly, interchangeable with conventional screw-in incandescent lamps, and sealed against contaminants from outside, is readily disassembled for replacement of its or ballast. Its two-piece non-conductive housing (Figs. 1-3) has first member (13) a flared open end (21) covered by lens (11) thereto an O-ring (9) smaller (27) second (15) small closed (24) having base (17) larger (22) fitting over the juxtaposed to outer surface (8), disengageably retained together fasteners (6) forming annular ballast compartment between overlapping ends. Ballast (40) fits in such 4A, 4B) on circuit board (41), which also accommodate (36) (30) 5A, 5B, 5C) extending thereinto portion member, reflective coating interior surface. Pin contacts (34) fit into contactor openings (44) (41) (40). The assembly accommodates 6A, 6B, 6C) combinations (10, 10', 10'') lamps different beam-spread angles (A, B, C) within canister type fixture (50) using extensions (51, 52) lengths.
