Florescent light fixture assembly

Claim 1

For insertion into a cylindrical housing for a lamp, said housing being secured in a circular ceiling opening, said housing having a side wall defining a cylindrical space and having an open lower end disposed in a common transverse plane and an upper closed end, said housing further having a first inside diameter and said housing having an aperture near its upper closed end to permit insulated electrical power wiring to be passed through the side wall adjacent the closed upper end of the side wall and extended to electrical connector means; a florescent lamp holding fixture, said fixture comprising an insulated plate disposed transversely within the cylindrical space intermediate the upper closed end and open lower end of the side wall, but more proximate to the said upper closed end, said plate having a maximum linear dimension less than the first inside diameter of the housing; a plurality of spring clip means secured to and extending transversely outwardly from said plate to provide a combined overall dimension of said plate and each of said clip means at least slightly greater than said first inside diameter of the housing, whereby said plate, when inserted axially into said housing, may be suspendedly retained transversely within the housing by said clip means; said plate having a first side facing the closed end of the side wall and a second side facing the open lower end of said side wall, said plate supporting on its first side a socket for a florescent lamp and a transformer and conductive means to form a circuit between the transformer and said socket and to connect said circuit through said power wiring to said electrical connector means, and said plate being orificed in alignment with said socket to enable a florescent lamp to be inserted into said socket from the second side of said plate, whereby, the florescent lamp will extend downwardly toward the open lower end of said side wall; and a reflector housing having a lower open end of a diameter only slightly less than said first inside diameter of the housing, and said reflector housing having an upper open end with a second diameter substantially less than the first inside diameter and the upper open end of said reflector housing being disposed about the orifice in alignment with the lamp socket in the plate and secured to the plate, said reflector housing having an increasing diameter from its upper open end to its lower open end, and said reflector housing having an axial length with the lower open end which terminates with the common transverse plane of the open lower end of the wall.
