Background technology
Solar energy (solar energy), refers to the infrared radiant energy (seeing three kinds of modes that heat energy is propagated) of the sun, mainly
Performance is exactly the sunray often said.It is typically used as generating in the modern times or provides the energy for water heater.From life on earth birth
Since life, the infrared radiant energy existence mainly provided with the sun, and also understand with sun dry part from ancient human, and as system
The method making food, such as salt manufacturing and solarization cured fish etc..In the case of Fossil fuel reduces increasingly, solar energy has become the mankind and has used
The important component part of the energy, and be constantly developed.The utilization of solar energy has photothermal deformation and opto-electronic conversion two ways, too
It is a kind of emerging regenerative resource that sun can generate electricity.Sensu lato solar energy also includes tellurian wind energy, chemical energy, water energy
Deng.
Solar energy is discharged huge nuclear energy by solar interior hydrogen atom generation hydrogen helium fusion and produces, from the sun
Emittance.
The overwhelming majority of necessary for human energy is all directly or indirectly from the sun.Plant discharges oxygen by photosynthesis
Gas, absorbing carbon dioxide, and solar energy is transformed into chemical energy stores in plant.Coal, oil, natural gas etc. are changed
Stone fuel is also to be developed, by the animals and plants being embedded in underground ancient times, the primary energy formed through very long geological epoch.The earth itself
The energy contained is often referred to the energy relevant with the heat energy of earth interior and the energy relevant with nuclear reaction.
In the middle of existing wireless technology, remove conventional radio frequency based on electromagnetic transmission information communication outside, also have based on
The radio communication of light, wherein, has communication technology based on iraser etc., also has wireless communication technology based on visible ray.Can
See optical communication technique, be that the naked eyes imperceptible high speed light and shade flash signal utilizing luminous diode to send is to transmit information
's.The data needing transmission are loaded on optical carrier, and are modulated, then utilize electrooptical device to receive light and carry
Ripple signal also demodulates to obtain information.Visible light communication system can cover the scope that light can reach, it is not necessary to electric wire is even
