Embodiment Construction
[0067] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments, and the content of the present invention is not limited to the following embodiments.
[0068] The present invention can use N LED lights to realize positioning. When N is 1 or 2, it can only be located within a certain range, and the positioning accuracy is low; when N is 3, the coordinate position of the user can be accurately calculated, but when a certain When a lamp fails, the positioning accuracy cannot be guaranteed; when N is 4, it can not only realize accurate positioning for the user, but also ensure normal positioning when the LED lamp fails, so N=4 is recommended, that is, the positioning unit is 4 LED lamps are distributed in a square, and the LED lamp array is expanded on all sides. The indoor lighting system is a palace grid unit topology network composed of more than one LED lamp array extended by 2 rows and 2 columns. The LED lamps locat...
