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.

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.

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.

An example horticulture device includes a housing. The housing includes a central cavity having an inlet and an outlet in fluid communication with the inlet through the central cavity. The horticulture device also includes at least one heat sink fixed relative to the housing. Each of the at least one heat sinks include a main body and a plurality of fins extending therefrom, a plurality of passages being provided between the fins of the at least one heat sink, between adjacent ones of the at least one heat sinks, or both. The horticulture device also includes at least one light source fixed relative to the at least one heat sink and in thermal contact with the at least one heat sink, and a fan disposed within the housing and configured to pass air through the plurality of passages and into the central cavity. A method is also disclosed.

The present disclosure provides a head-up display that has a first lighting unit to display first information on a windshield. The first lighting unit includes a first lighting source that emits light for the windshield as the first information and a first cylindrical casing that accommodates the first lighting source therein. The head-up display further has a second lighting unit to display second information on the windshield. The second lighting unit includes a second lighting source that emits light for the windshield as the second information. The head-up display further has a package disposed under the windshield. The first and second lighting units are installed on the package. The second lighting unit is installed on the package independently from the first lighting unit.

In various embodiments, a lamp is provided. The lamp may include a mounting board; at least one semiconductor light source arrangement arranged on the mounting board and comprising a base, which is provided with base contacts for supplying energy to the at least one semiconductor light source arrangement and which is compatible with a standardized incandescent lamp base; and at least one insulation displacement contact to make electrical contact with the at least one semiconductor light source arrangement.

Provided is a heat dissipation structure and an illumination device which are capable of dissipating heat readily and efficiently. A heat dissipation structure 1 configured to release heat from a heat source 100 is provided with a plurality of heat reception/dissipation members 10 which have expanded graphite layers containing expanded graphite and which are spaced apart from each other; and a connection member 20 configured to connect the heat reception/dissipation members 10 together. The heat reception/dissipation members 10 each have the expanded graphite layer as the outermost layer and are disposed such that the expanded graphite layers face each other.

A system and method for a light panel assembly which is particularly useful for commercial horticultural applications. An extruded heat sink frame provides for a layered light panel assembly with superior heat dissipation characteristics and low power requirements while providing highly efficient returns and output radiant flux.

An LED illumination device includes: an LED substrate on which an LED package is mounted; a base having a concave part for housing the LED substrate; a heat sink; a cooling fan; and a casing housing the LED substrate, base, heat sink, and cooling fan. The heat sink is constituted of a rectangular flat plate which is thermally connected to a surface of the base opposite to the surface in which the concave part is formed and a plurality of rib-shaped heat radiation fins which is disposed on a heat radiation surface of the flat plate opposite to the surface thereof thermally connected to the base such that both ends of each thereof protrude outward from a pair of opposing sides of the flat plate. The base is formed into a shape from which the part of each heat radiation fin that protrudes from the flat plate is exposed.
