Embodiment Construction

[0031] The present invention will be described in detail below with reference to the drawings and embodiments.

[0032] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] The present invention provides a LED array layout method in a visible light communication system. The method takes into account the advantages of energy saving, uniform illumination and reliable performance. The layout scheme includes the following eight steps:

[0034] ①. Determine the parameters of the indoor space, and establish the three-dimensional coordinate system of the indoor space;

[0035] ②. Determine the height of the receiving plane in the indoor space and the coordinates of the receiver on the receiving plane;

[0036] ③. Determine the light source parameters of the visible light communication system and the illuminance radiation model of the point light source;

[0037] ④. Give the illuminance radiation mod...

Abstract

The invention relates to a layout method of an LED array in a visible light communication system. The method comprises the steps of firstly giving an indoor space model and obtaining space parameters in the indoor space model; obtaining radiation characteristics of a single point light source through analyzing the radiation node of the single point light source and then giving the radiation characteristics of the LED array; and determining the size of the LED array and building a mathematic model of taking the illumination uniformity and the communication reliability into account through the radiation characteristics of the array on an indoor ceiling and finally obtaining indoor LED array layout parameters capable of taking the energy consumption, the illumination and the communication reliability into account. The layout method is simple in operability, can be expanded to any size of room and has feasibility, and an effective way can be provided for indoor light source layout of the visible light communication system.

Description

technical field [0001] The invention belongs to the technical field of visible light communication, and in particular relates to an LED array layout method in a visible light communication system. Background technique [0002] Visible light communication technology is a new type of wireless data transmission method that loads information onto white LED light sources. Compared with traditional lighting equipment, white light LEDs must take into account both lighting and communication tasks in indoor visible light communication. Therefore, in the light source layout It is necessary to consider the uniformity of illumination distribution, communication reliability and system power consumption at the same time. [0003] From the perspective of indoor lighting, it is often hoped that all places in the room can obtain better illuminance, there is no shadow effect, and the change of illuminance at various positions in the room is not very large; from the perspective of indoor optic...
