Abstract: A U-turn lens for a recessed light fixture comprising a tubular, transparent, internally reflective, hollow cylindrical lens having a closed top including a hot mirror receiving focused light from a reflector lamp, an inside diameter extending to an open lower end where focused light is emitted and collimated light is received through the lens outside the inside diameter to an angular reflector reflecting the collimated light transversely to illuminate a concave decorative shade.

Abstract: This invention integrates energy saving lighting with energy saving HVAC (Heating, Ventilating and Air Conditioning). This system is termed by the inventor “ILAC” (Integrated Lighting and Air Conditioning). An ILAC system includes light fixtures mounted in a ceiling and, emitting lamp heat into a plenum and visible light into a room. A central computer controls both lighting and HVAC systems. In a COOL mode an HVAC unit cools the room through a supply air duct and return air duct, and the lamp heat exits the plenum through an exhaust duct. In a HEAT mode the HVAC heats the room through the same supply air duct, a ceiling-to-plenum duct carries the heated room air into the plenum, and an HVAC return air duct carries room and plenum heat back into the HVAC unit that uses less power to heat the lamp-warmed return air. In a thermostat-controlled OFF mode, warm room air convects through the ceiling duct into the plenum and exhausts through a plenum exhaust duct along with lamp-heated plenum air.
