Embodiment 1

[0022] Such as figure 1 As shown, the LED communication system of this embodiment includes an LED lighting communication device 1 and a receiver 7. The LED lighting communication device 1 includes a multi-chip visible light band LED2, an infrared light band LED3, an information carrier 4, and a communication controller 11. The communication controller includes a power supply 5 and a light modulation / control module 5. The power supply 5 drives the light modulation / control module 5 to read the information in the information carrier 4 and send them to the multi-chip visible light band LED2 and the LED lighting communication device 1 respectively. The receiver 7 includes Solar battery 8, band pass filter 9, earphone 10. Among them, LED lighting communication devices such as figure 1 As shown, here, the multi-chip visible light band LED2 is respectively provided with red, green and blue LED chips. Its specific location distribution is as follows image 3 shown. The three colors...

Abstract

The invention discloses an LED lighting communication device and an LED lighting communication system. The LED lighting communication device comprises a communication controller, a multi-chip visible light wave band LED and an infrared wave band LED, wherein the communication controller sends signals to the multi-chip visible light wave band LED and the infrared wave band LED. Therefore, through different multi-chip lighting, lighting effects of formed white light can be superposed on the one hand, and a plurality of communication channels with an independent wave band can be acquired on the other hand, thereby meeting more communication requirements.

Description

technical field [0001] The invention relates to an LED lighting communication device, which belongs to the technical field of light source lighting and optical communication. Background technique [0002] With the continuous improvement of light-emitting diode (LED) luminous power and luminous efficiency, it has gradually become a new generation of mainstream lighting appliances. Since LED is a current-mode semiconductor device, the intensity of light can be changed by controlling the driving current, so as to achieve the purpose of carrying signals. That is to say, the LED can be used as a light source to transmit information in free space. And because the LED emits soft and direct incoherent light, it will not damage the human body like a highly coherent laser, nor will it be restricted by the radio wave law like a wireless carrier, and there will be information leakage. In this way, we can use the existing lighting infrastructure to construct such a ubiquitous mobile co...
