Background technology
Along with improving constantly of Light-Emitting Diode (LED) luminous power and luminous efficiency, it has become the main flow ligthing paraphernalia of a new generation gradually.Because LED is current mode semiconductor device, so the power of light can be changed by controlling drive current, thus reach the object of carrying signal.That is can make LED while as lighting source, at free space transmission of information.Again because LED sends is the incoherent light of soft direct projection, therefore it both can not resemble the very high laser of coherence and damage human body, also can not resemble the restriction being subject to electric wave method wireless carrier, and there is leakage of information phenomenon.We just can utilize existing lighting infrastructure like this, construct such one all over mobile communication environment, in this environment, as long as the place having illumination light to arrive, can information exchange be carried out, and not need to arrange special communication equipment.And leakage of information need not be worried and affect other people.
But, with illuminating light communication, can because the light modulation/toning of ligthing paraphernalia causes the instability of Communication ray intensity.Some users are also had to wish after turning off the light, still can to obtain acoustic information.On the other hand, for 1 mobile communication environment, the power source life of the recipient that user carries with also is 1 important problem.Also having because the blind person of about 80% can be photosensitive, so can blind person facilitate blind person independently to carry out information exchange, be also one of theme setting up hommization society.
Summary of the invention
Goal of the invention: the object of the invention is to solve following problem: the monochromatic light 1) controlling and operate the different wave length comprised in white illumination light independently; 2) monochromatic light of each wavelength is the independent channel of a respective acoustic information of carrying; 3) channel of infrared band is used for compensating illumination device and loses because light intensity that light modulation/toning produces changes the communication performance caused; 4) channel of infrared band may be used for information transmission when not needing illumination; 5) recipient is 1 light-electricity-sound converting apparatus not needing power supply; 6) recipient can be made bending small portable card freely or ticket etc.; 7) blind person is facilitated independently to use.By control and the process of above-mentioned 7 aspects, common lighting environment can be made to become information to be provided and service environment.
Technical scheme: LED illumination communicator of the present invention, comprise communication controler, multi-chip visible light wave range LED, infrared band LED, signal is sent to multi-chip visible light wave range LED and infrared band LED by described communication controler respectively.Like this by the illumination of different multi-chips, the illuminating effect forming white light can be superposed on the one hand, the communication channel of multiple independently wave band can be obtained on the other hand, meet more communication requirement.
Further, described multi-chip visible light wave range LED is the multi-chip visible light wave range LED comprising blue wave band LED, red spectral band LED and green light band LED, and signal is sent to multi-chip visible light wave range LED by being connected with blue wave band LED, red spectral band LED and green light band LED respectively by described communication controler.
Further, also comprise information carrier, described communication controler comprises power supply and light modulation/control module, described power drives light modulation/control module, after data in light modulation/control module reading data media, signal is sent to respectively multi-chip visible light wave range LED and infrared band LED.
The present invention also comprises the LED illumination communication system being provided with above-mentioned arbitrary described LED illumination communicator, also comprise receiver, described receiver comprises solar cell, bandpass optical filter, earpiece/speaker, described band pass filter covers on described solar cell, described solar cell is sent to described optical communication demodulation/control module after receiving the communicate optical signal through band pass filter, the voice signal after demodulation is sent to earpiece/speaker by described optical communication demodulation/control module again.
Further, described band pass filter is blue green light band pass filter, red band bandpass filter or infrared light band pass filter.
Further, the quantity of described receiver is 3, and the band pass filter of 3 receivers is respectively blue green light band pass filter, red band bandpass filter, infrared light band pass filter.
Blue wave band scope in the present invention is 435 ~ 450nm, ultraviolet band scope is 100-400nm, green light band scope is 492 ~ 577nm, red spectral band scope is 622 ~ 760nm.
The prior art that the present invention utilizes illumination light to carry out point-to-point communication is embodied in transmitting terminal and receiving terminal two aspect respectively.
1) transmitting terminal technical scheme: the communication means (ZL200380104093.2) of LED light device; Realize the method (Japanese Laid-Open Patent 2011-055397) of high-speed communication.
2) receiving terminal technical scheme: the method (Japanese Laid-Open Patent 2011-055397) realizing high-speed communication; Portability and versatility (the visible light communication camera of CASIO and calculator).
Compared with prior art, its beneficial effect is in the present invention: the transmitting terminal of technical solution of the present invention adopts intensity compensation during light modulation/toning; Send different information with 1 lighting device simultaneously; And describe the optical communication problem not needing the dark place of throwing light on.Receiving terminal of the present invention, prevents the power-off in mobile communication process to cause the problem of communication disruption, and uses thin-film solar cells, allows when carrying and can bend freely.The present invention uses solar cell as light receiving element, and recipient is become does not need the light-electricity-sound converting apparatus of power supply and electronic circuit.
