Abstract: A traffic barricade light is described. A housing comprises a collar, a bottom side, a height, a width and a depth. The housing is divided along an axis positioned within the depth. The housing comprises at least two angled walls on opposing shoulders of the housing within the depth at an oblique angle relative to the bottom side of the housing. Each angled wall comprises a recess and a passage from the recess to a compartment within the housing. A solar panel is coupled to each angled wall. The solar panels are electrically coupled in parallel with each other and with at least one rechargeable battery stored within the housing. A regulator circuit is electrically coupled between the at least two solar panels and the at least one rechargeable battery. A light source is electrically coupled to the battery. A lens is coupled to the collar.

Abstract: Disclosed is a liquid cooled LED light bulb comprising at least one shaped tube positioned so as to conduct ambient heat away from the LED light source using passive cooling. In the most preferred embodiments of the present invention, a plurality of shaped tubes are arranged in an array and attached by various methods to the LED light source of the LED light bulb. The tubes of the cooling array may be in any closed circuit geometry and configured so as to contain any interior liquid that is suitable for the conduction of heat. In certain preferred embodiments of the present invention, a plurality of tubes may be arranged in a circular array or any other array configuration. In certain preferred embodiments of the present invention, an array of tubes may be below an LED mounting, but other configurations may include a tubular array substantially surrounding the LED mounting.

Abstract: The use of an LED light source coupled with an integrated heat sink is described in this application. The most preferred embodiments of the present invention comprise an LED light source surrounded by a plurality of heat vanes, with each heat vane comprising a plurality of heat fins, all positioned to dissipate heat in an enclosure housing the LED light source. In at least some preferred embodiments of the present invention, a pair of waterproof tubes are used to house a pair of electrical conductors that are used to connect the LED light source to a power source. The most preferred embodiments of the present invention further comprise a single LED contained in a housing fitted with a compound parabolic concentrator configuration.
