Abstract
A switchable illumination system adapted to provide illumination to a device is disclosed. The switchable illumination system comprises a first light source, a second light source, a reflection module and a control module, wherein the two light sources are disposed on opposite sides of the reflection module, respectively. The reflection module is adapted to reflect the light emitted from either the first light source or the second light source to maintain normal operation of the switchable illumination system under the monitoring of the control unit.
