Problems solved by technology

[0004] However, when the existing visible light signal transceiver device receives or transmits visible light signals, due to its own structural limitations, the visible light signal transceiver device can only transmit and receive visible light signals within a specified angle, so that the staff are installing it. When using the visible light signal transceiving device, it is necessary to consider the signal receiving and sending angle of the visible light signal transceiving device to ensure that the visible light signal sent by the transmitter can be received by the receiver. High, once the position is shifted during installation, it will affect the strength of the signal

Abstract

The invention relates to a visible light signal transceiver, which comprises a light emitting unit capable of emitting a visible light signal and a light receiving unit capable of receiving the visible light signal, wherein the light emitting unit is provided with a light signal emission surface for emitting the visible light signal, and the light receiving unit is provided with a light signal receiving surface for receiving the visible light signal emitted by the light emitting unit. In comparison with the prior art, the light emitting unit and the light receiving unit are capable of emitting and receiving the visible light signal through the forms of the light emitting surface and the light receiving surface respectively, so that the signal intensity of the visible light signal transceiver during communication is improved through increasing the areas of the light emitting unit and the light receiving unit when emitting and receiving the visible light signal.

Description

technical field [0001] The invention relates to a wireless signal transceiving device, in particular to a visible light signal transceiving device. Background technique [0002] Visible Light Communication technology (Visible Light Communication, VLC) refers to a communication method that uses light in the visible light band as an information carrier and directly transmits optical signals in the air without using optical fiber and other wired channel transmission media. [0003] At present, common visible light signal transceiver devices generally use visible light light-emitting diodes, that is, LEDs as illuminants. Compared with fluorescent lamps and incandescent lamps, LEDs have faster switching speeds, and use large indoor and outdoor display screens equipped with LEDs, lighting equipment, The information is modulated and transmitted by high-speed modulated light wave signals that are invisible to the naked eye, and then photoelectric conversion devices such as photodiod...
