Document Type and Number:

WIPO Patent Application WO/2012/161390

Kind Code:

A1

Abstract:

Embodiments of the invention provide optical semiconductor-based tube type lighting apparatuses. The optical semiconductor-based tube type lighting apparatus includes an elongated light-transmitting tube, and a plurality of optical semiconductor modules arranged along a circumference of the light-transmitting tube and separated from each other in a cross-sectional view of the light-transmitting tube. Here, each of the optical semiconductor modules is placed so as not to face another optical semiconductor module at an opposite side thereof.
