Abstract
A lighting apparatus includes a driver, a first branch, a second branch, a first switch, a second switch, multiple middle switches, and a switch control unit. The first branch includes multiple first LED modules. The multiple first LED modules are divided into multiple first segments. There are first nodes between adjacent first segments. The second branch includes multiple second LED modules. The multiple second LED modules are divided into multiple second segments. There are second nodes between adjacent second segments. The switch control unit is used for controlling selections of the first switch, the second switch and the multiple middle switches for determining a conductive path of a selected set of LED modules selected from the multiple first segments and the multiple second segments for mixing a required optical parameter.
