Abstract

The invention provides a binary free-form surface visible light communication transmitting antenna and a design method thereof. The design method comprises the following steps: establishing a free-form surface condenser model; determining a relationship among incidence, reflection and a free-form surface normal vector of a free-form surface condenser according to a Snell law and a partial differential equation so as to determine the slope of each point of the free-form surface, and calculate the surface type of the free-form surface condenser; and calculating coordinates of an LED light source, the free-form surface and an irradiation surface under a reference coordinate system, and establishing a light-emitting model of the LED light source and the binary free-form surface. The antenna and method can be used to effectively improve the communication distance, reduce the bit error rate, improve the illumination intensity and the like, improves the overall attribute of a visible light communication system, and has a great application prospect.

Description

technical field [0001] The present invention relates to the technical field of visible light communication, in particular to a binary free-form surface visible light communication transmitting antenna and a design method thereof. Background technique [0002] Visible light communication is a new type of communication. The receiving optical antenna is an important part of the LED visible light communication system. It can collect weak signals scattered by the atmosphere and filter them. Visible light communication technology uses fluorescent lamps or light-emitting diodes. The high-speed bright and dark flickering signals invisible to the naked eye are used to transmit information. Connect the high-speed Internet wire device to the lighting device and plug it into the power plug to use it. The system made by this technology can cover the range of indoor lighting. Computers do not need wires to connect, so they have a wide range of development prospects. Compared with the curr...
