20090032604 | Energy saving integrated lighting and HVAC system - 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. Optionally, plenum exhaust duct may include a radiator to transfer plenum heat to pre-heat water entering a remote hot water heater. | 02-05-2009 |

20090135610 | Recessed light fixture for luminous ceilings - The present invention is for a compact, light-weight, inexpensive, spider-shaped light fixture for luminous ceilings in which the fixture comprises a housing in the form of an inverted U-shaped reflector located above and between T-bar runners, with angular struts attached to the housing and extending out to be engaged onto the tops of T-bar runners on either side of a luminous-ceiling panel. The housing includes one or more self-ballasted, scew-based compact fluorescent and/or optional incandescent lamps that are installed into 3-way, remotely-switched lampholders capable of operating either 3-way, single-circuit incandescent, or various gas-discharge lamps. | 05-28-2009 |
20090168423 | Energy-saving recessed tracklight system - A tracklight system includes an elongated an elongated metallic track in the shape of an inverted U having a generally horizontal base with parallel, vertical depending sides, each side terminating at a distal end in a common plane with an outward facing support flange for a ceiling panel. The inward-facing side of at least one side supports an elongated 3-conductor electrical receptacle having polarized longitudinal slots holding electrical conductors therein. A number of lamp assemblies are positionable in longitudinal slots each with flexible wires terminating in a plug matching the polarized electrical receptacle. A thermal barrier in the ceiling plane prevents lamp heat from radiating in the downward direction into a room. | 07-02-2009 |
20090251907 | Reflector lamp filter adapter - A reflector lamp filter adapter according to the present invention comprises a generally U-shaped resilient bracket having a base and 2 parallel sides wherein the base and sides have slots adapted to receive and hold the rim of a reflector lamp emitting visible light, IR (infrared heat) and UV (ultraviolet) energy; a heat-reflecting, light-transmitting hot mirror; a heat-absorbing filter; and in one preferred embodiment, a UV-blocking filter. The U-shaped bracket has a lock engaging the distal edges of the sides of the U, securely locking the lamp reflector and filters therein. The bracket includes convection cooling apertures so the final light beam is only visible light, with no ultraviolet of infrared energy. | 10-08-2009 |
