Abstract
A refrigerator providing automatically adjustable inside illumination and compressor operation speed. An optical sensing unit is used to sense the ambient light brightness proximate to the refrigerator. The brightness of the inside lamps are adjusted based on the sensed ambient light brightness so as to prevent glare to a user who opens the refrigerator in the dark. The sensed ambient light brightness is also used to control the operation speed of the compressor. If the ambient lighting condition indicates it is night time, the compressor can run at a reduced speed and so produce less operation noise.
