Lighting system that can change light emitting characteristic and lighting device and lamp holder of the lighting system

摘要

A lighting system includes a carrier unit, and a lamp holder including a holder plate for mounting of a light emitting unit, and a first positioning plate and a second positioning plate extending from the holder plate and spaced apart from each other. The holder plate is disposable at a first or second position when the first or second positioning plate is connected to the carrier unit. A light emitting characteristic of the light emitting unit when the holder plate is in the first position is different from a light emitting characteristic of the light emitting unit when the holder plate is in the second position.
