摘要： An assimilation lamp device (101; 800) for stimulating plant and crop growth comprises: a central lamp unit (10), comprising a body (14) and one or more LEDs (12) mounted to the bottom surface of the body, wherein the body acts as a heat sink for the heat generated by the LEDs. The device further comprises air stream generating means (42) for generating a downward air stream (43; 341), and heat transfer and exchange means for transferring heat from the body to the air stream, so that heat from the LEDs is used to increase the temperature of said downward air stream and is eventually used to warm the environment of the plants. A device controller (850) has a set point input (859) and generates control signals for the LEDs and the air stream generating means in conformity with an input signal received at its set point input.

摘要： A lighting apparatus for use as a surgical headlamp is disclosed. A light emitting diode is positioned in a recess within a frustoconical, thermally-conductive heat sink that has a several circumferential ridges to provide a desired surface area for heat transfer. The diode and the heat sink are provided in a housing that also includes a fan for drawing ambient air into the housing to contact the heat sink and exhausting heated air. A lens is snap-fit into a slide that frictionally engages the interior of the housing, allowing a user to adjust the spacing between the light emitting diode and the lens as desired. Personal cooling apparatuses usable with the lighting apparatus are also described. Auxiliary undergown switches are also described as are personal cooling apparatuses.

摘要： A material (such as potassium hydroxide or ammonia) capable of reacting with ambient carbon dioxide to produce fertilizer is placed in the path of ambient air movement. Desirably the material is associated with a fabric which in turn is associated with a vane of a vertical axis wind turbine, the turbine performing useful work as well as supporting the material which produces a fertilizer. A misting system controlled by a controller may automatically apply a water mist to the material if the humidity is below a predetermined level. The fabric with produced nitrogen and/or potassium fertilizer may be placed directly into contact with soil, or shredded first, or burned to produce energy and an ash (and the ash applied to the soil). The wind turbine may have a convenient, versatile mounting system with three adjustable legs supporting a central component, and the spokes of the wind turbine may be slotted for easy assembly with vanes.

摘要： Improvements a portable elevated lighting system that uses LED lighting elements for illumination. The LED lights are selected based upon the light transmission angle so the fewest number of lighting elements are needed to provide an even flood or focus of light from the system. A reflector works as a heat sink to remove heat from the LED lights and extend the operation life of the LED's. Thermal paste and or a thermal pad is used between the LED lighting element and the frame to conduct sufficient heat away from the LED element. Two versions are shown as a stadium light and as a circular flood light that provides lighting without shadows or bright areas. The system can be operated from a generator or solar for charging batteries so the lighting can operate self-contained without producing noise.
