The LED light module assembly includes a light source having a printed circuit board containing an LED driver and LEDs. The printed circuit board is directly attached to a mounting plate that includes a thermally conductive and radiating material. An LED cover overlies the LEDs. Spring retainer clips hold a decorative trim ring in a spaced-apart relationship from the mounting plate, creating an air gap for cooling and keeping the trim ring cool. A light diffuser lens has hooked legs that twist lock to the mounting plate and diffuses the light from the LEDs. ## Claims ### Claim 1 An LED light module assembly for direct attachment to an electrical junction box having an opening, comprising: an LED driver and a printed circuit board with at least one LED disposed thereon; a mounting plate having a top surface and a bottom surface, the mounting plate including a thermally conductive material, wherein the printed circuit board is directly mounted to the bottom surface of the mounting plate for thermal conduction therebetween, wherein the top surface of the mounting plate engages with the junction box at the opening, and wherein the mounting plate includes exposed areas on the top and bottom surfaces to radiate heat; a retainer means disposed on the mounting plate and extending away from the bottom surface of the mounting plate; and an LED cover engaging the mounting plate, overlying the at least one LED; and a trim ring having an open area exposing the LED cover, wherein the trim ring engages the retainer means with an air gap between the bottom surface of the mounting plate and the trim ring. ### Claim 2 (depends on 1) The LED light module assembly of claim 1, wherein the trim ring overlies the mounting plate. ### Claim 3 (depends on 1) The LED light module assembly of claim 1, wherein the mounting plate is assembled to the junction box using fasteners. ### Claim 4 (depends on 1) The LED light module assembly of claim 1, wherein the retainer means includes spring clips that include hooks. ### Claim 5 (depends on 1) The LED light module assembly of claim 1, wherein the LED cover is generally flush with the trim ring for a low a profile. ### Claim 6 (depends on 1) The LED light module assembly of claim 1, wherein the retainer means includes a plurality of spring clips arranged circumferentially around the printed circuit board. ### Claim 7 (depends on 1) The LED light module assembly of claim 1, wherein the mounting plate includes one of a polygonal shape and a circular shape. ### Claim 8 (depends on 1) The LED light module assembly of claim 1, wherein the LED cover includes a circular shape with a diameter much greater than a height thereof. ### Claim 9 (depends on 1) The LED light module assembly of claim 1, wherein the assembly includes a junction box adapter fitted between the mounting plate and the junction box, wherein the junction box adapter includes at least one of a square shape with an open center, an L-shape, and a boomerang shape. ### Claim 10 An LED light module assembly for direct attachment to an electrical junction box having an opening, comprising: an LED driver wired to a printed circuit board to energize at least one LED, the at least one LED being disposed on the printed circuit board;
