Definitions
- the invention relates to a method for the wireless transmission of energy emitted by at least one light source in enclosed spaces, in which the light energy emanating from the light source is received by at least one solar cell module arranged in the space and converted into electrical energy. Furthermore, it relates to an apparatus for carrying out this method.
- wireless energy transfer generally refers to the transfer of electrical energy from an energy source to an electrical load without a conductive physical connection.
- Solar cell module is received and converted into electrical energy, has become known from US 2009/010 3 925 AI.
- DE 10 2009 055 684 AI a system for increasing the yield of photovoltaic systems for feeding energy into an AC mains, for heating support and hot water has become known, in which the photovoltaic system is operated by the supply of artificial light.
- DE 102 33 005 B4 a similar arrangement has become known from DE 102 33 005 B4, in which an artificial light source and PV modules are provided in a device for supplying a sensor located at a high electrical potential in a paint shop with electrical energy.
- an energy storage which consists of an evacuated storage vessel, which is highly reflective mirrored inside the entire surface and the input side is connected in each case via locks on the output side, each with a further vessel.
- the input-side vessel is also mirrored in this known arrangement, while the output-side vessel is completely lined with solar cells, which are provided for discharging the electric power with outwardly reaching terminals.
- the first object of the invention is to design a method of the type mentioned in such a way that it exploits the properties of the available surface materials of the closed space and that it can be used in particular for space missions.
- an apparatus for carrying out this method is to be provided by the invention.
- the invention achieves the first object by providing a method in which at least part of the light energy emanating from the light source is reflected at a reflecting surface in the interior of the room and then received in the at least one solar cell module and converted into electrical energy.
- the solution of the further object is achieved according to the invention in that in an arrangement according to the preamble of the new claim 2, at least a portion of the space has a consisting of a multi-layer Insulations- surface reflective inner surface on which the at least one light source outgoing light energy is reflective.
- the advantages of such an arrangement are, on the one hand, that the light source or a plurality of light sources can be placed flexibly in the interior of the room, that, moreover, the distribution of the light can be optimized by the reflecting surface and, in addition, the placement of the solar cell module comparatively is not critical to a successful application of the method according to the invention.
- a plurality of light sources can be provided.
- a plurality of reflective surfaces of different nature may be provided.
- the light source (s) can be turned on and off as needed, and can be used both with coherent and with incoherent light in the visible as well as in the invisible range, i. in the infrared and ultraviolet light range.
- the figure shows a wireless energy transfer device using reflections on multi-layer insulation or MLI surfaces for a wireless sensor network in space missions.
- a light source 2 is located in a closed room whose walls 1 are lined with MLI surfaces.
- a solar cell module 3 receives the light either directly or through reflections on the MLI surfaces.
