Abstract

A lighting apparatus includes a first light source, a second light source, a first reflective cup, a second reflective cup, a base housing and a driver. The first light source is used for emitting a first light. The second light source is used for emitting a second light. The first reflective cup is used for limiting the first light in a first scope. The second reflective cup is used for limiting the second light in a second scope. The base housing is used for disposing the first reflective cup and the second reflective cup. The driver selectively provides a first driving current to the first light source and a second driving current to the second light source.
