Abstract

The invention discloses a button-controlled visible light vehicle lamp signal sending device. The device includes a power supply module, a button, an energy storage module, a voltage stabilizing module, a transmission control module, a driving module and a vehicle light. The device provides lighting mode and communication mode. The switch signal generated by the button action control realizes the mode switching. The sending control module receives the button command and activates it from the dormant state, and generates the switch signal according to the power supply on and off, and the sending control module Power is supplied by the power supply module or the energy storage module, and a driving signal is generated, and the driving module drives the lamp to send a visible light signal according to the driving signal. The device of the invention has a simple structure and is easy to operate. It is directly embedded in the original car lamp circuit, and can be used without changing the original structure. The communication function is simply activated to send visible light signals. The power loss and device life loss of the device are small, the stability is high, the service life is long, and the safety is good.

Description

technical field [0001] The invention belongs to the technical field of optical communication, and in particular relates to a key-controlled visible light vehicle light signal sending device. Background technique [0002] Visible Light Communication (VLC) is a communication method that uses high-speed modulated visible light emitted by light-emitting diodes as an information carrier to transmit optical signals in the air. This technology uses high-speed modulated light wave signals that are invisible to the naked eye from indoor and outdoor large-scale display screens equipped with LEDs, lighting equipment, and automobile front and rear lights to modulate and transmit information, and then uses photoelectric devices with high light sensitivity and high-speed response to receive optical carriers. signal and get information. [0003] Light language is a common communication tool, which uses the light to make signals of different lengths to convey information. In ancient times...
