Lighting device

Abstract

A lighting device is formed of a bistable spring, a housing, a flexible light guide member, and a lighting module. The bistable spring is changeable between an uncurled state and a curled state and includes a springy main body and a covering layer. The covering layer covers the springy main body. The housing is fixed to the bistable spring. The flexible light guide member is connected with the bistable spring and includes two terminal portions. The two terminal portions of the flexible light guide member are inserted into the housing. The lighting module is mounted inside the housing for emitting light toward the two terminal portions. In this way, the lighting device is easy for assembly and energy-saving.
