Description

Technical Field

[0001] This invention relates to the field of lighting equipment technology, and more specifically to a lighting fixture device. Background Technology

[0002] In existing lighting fixtures, such as those in libraries or large living rooms, there are often multiple seats for people to sit and read. Some of these seats are arranged around a central pillar and are illuminated by lights from the ceiling, which has limited lighting effect. Reading lights placed next to the seats also take up too much space and are easily knocked over by people walking around, thus limiting their effectiveness. Summary of the Invention
