Abstract: A self-centering hyperbolic trim assembly is provided for a recessed light fixture. The trim assembly includes a mixing chamber, a hyperbolic reflector and a reflector mounting assembly to mount the hyperbolic reflector without rigid attachment in an optic housing of the recessed light fixture. The mixing chamber is top mounted by its chamber holder portion over an LED light source in the optic housing. The mixing chamber has a light transmitting chamber body held within the chamber holder portion, whereby a space is formed between the chamber holder and the light transmitting chamber body. This space is sufficient to accept the free upper end of the hyperbolic reflector therein, thus creating a self-centering interference fit between the mixing chamber and the reflector, while protecting the LED light source, when the light fixture is assembled, thereby maintaining consistent light output and patterning.

The lamp shade has a center ring at the mid-point of its diameter and, furthermore, an opening is formed from a through-hole in the center ring towards its circumferential edge that accommodates the insertion of a power cord. A collar projects downward vertically from the centered annular edge of the through-hole of the center ring such that the collar is around the periphery of a threaded rod, and the insulator sleeve and the light bulb unit are situated at the bottom end of the lamp shade. Furthermore, a washer is installed between the insulator sleeve and light bulb unit that leaves an intervening space of separation, thereby providing for the directed flow of light bulb heat to reduce the interior temperature of the lamp shade.

Abstract: The invention has a top ring, a bottom ring, of which the perimeter is greater than that of the top ring, and a support frame connecting the top ring and the bottom ring. Near the support portion of a support frame, there are support bars extending radiantly from the top ring and the end of the bars are bent upward to fasten the clip hooks on the ring rim. After the assembly of the support frame, the upper transversal arch bars exactly hit the bottom rim of the clip hook on the top ring to firmly fix the support frame. Also, near the support portion on a support frame, there are fixture bases located accordingly on the bottom ring for the insert and positioning of bottom bars on the support frame. The lamp cover can thus be assembled with minimum volume to achieve the objectives of easy assembly and to reduce storage volume and delivery cost.
