Abstract:
Ветросветильник, выполненный, например, в форме флюгера, содержащий лопастной ротор, генератор электрической энергии установленный на подвижном секторе, осветительный элемент установленный на том же секторе, при этом на по меньшей мере части поверхности подвижного сектора установлено по меньшей мере одно двухслойное покрытие, один слой которого выполнен из светоотражающего материала, а другой выполнен из световода оптически связанного с по меньшей мере одним осветительным элементом.
Abstract:
A lamp-post supports a lighting unit in the form of an array of LED's (11). The LED's (11) are supplied with power from a local battery (8) under the control of a control circuit (13). The local battery (8) is recharged from a local solar cell (17). The charging of the local battery (8) may be augmented y current supplied from a local wind powered generator driven by a fan (5). The control circuit (13) supplies the LED's (11) with pulses of current at a rate faster than can be perceived by the human eye and for a duration that gives the impression of a constant light source.
Abstract:
A solar or self-powered assembly includes a rechargeable battery and photo voltaic panel and/or wind turbine for supplying a battery charging current. A charge controller processor is controls charging current from the photovoltaic panel and/or wind turbine to maintain the battery in a substantially fully charged state of 80% or more state of charge over daily charge and discharge cycle charging is based on a projected target energy input based on the initial bulk energy charge, the level of discharge required to compensate for charging inefficiencies and the battery capacity factor representative of the projected natural charge in the battery over its lifespan.
Abstract:
The present invention provides an illumination device comprising an elongated support element (10) with an illumination source (20) integrated therein. Preferably the elongated element is collapsible, telescopic or resiliently flexible. It may comprise a plurality of sections (11, 12) which are adapted to reciprocate between a retracted configuration and an extended configuration. The device is particularly suitable for temporary or collapsible structures such as tents, umbrellas, awnings, shades or the like.
Abstract:
Le dispositif d' éclairage à diodes électroluminescentes (LED), tel que l'éclairage urbain ou analogue, du type comprenant : un carter support et de protection (24) dont une face laisse passer la lumière, des moyens porteurs (29) fixes, fixés au et logés dans le carter, définissant un référentiel fixe, une pluralité de LED (30) avec leurs circuits imprimés (31) portées par et fixées en position aux moyens porteurs (29), disposées côte à côte et logées dans le carter, est caractérisé en ce que, les LED successives de la pluralité de LED (30) étant positionnées sur les moyens porteurs avec des inclinaisons relatives successives progressivement différentes, de sorte que leurs axes soient dans des positions angulaires relatives successives progressivement différentes par rapport au référentiel.
Abstract:
Provision for electrical power supplies which combine solar power generation and turbine power generation are useful at remote locations. By combining two forms of power generation the problem with respect to inconsistency of supply are avoided. Furthermore optimizing solar panels, electrical power generation and in particular turbine configurations aid operational performance enabling a practical electrical power supply.
