1. Technical Field
The present disclosure relates to illumination devices and, particularly, to an illumination device capable of self adjusting the brightness and a method thereof.
2. Description of the Related Art
Nowadays, illumination devices with light sensors are very popular. The light sensor can sense the ambient light intensity and the device can adjust the brightness of a light-emitting element according to the sensed ambient light intensity. However, the light provided by the light-emitting element may affect the sensed ambient light intensity, resulting that the device may not accurately adjust the brightness of the light-emitting element.
