Abstract
A lighting apparatus is provided. The lighting apparatus includes a first light source module and a second light source module surrounding the first light source module. A half beam angle of the first light source module is smaller than a half beam angle of the second light source module. A correlated color temperature of light from the first light source module is higher than a correlated color temperature of light from the second light source module.
