Abstract

In some embodiments, a lighting apparatus includes a light source plate, a first LED module, a second LED module, a plastic cover and a controller. The first LED module is mounted on a first area of the light source plate. The second LED module is mounted on a second area of the light. The plastic cover has a first region facing to the first LED module for forming a first light spanning region. The plastic cover has a second region facing to the second LED module for forming a second light spanning region. The controller generates a first driving current to the first LED module and a second driving current to the second LED module. The controller adjusts a ratio between the first driving current and the second driving current to create a mixed light spanning region with a required mixed light pattern.
