LD OD 5483 LUMINAIRE ABSTRACT OF THE DISCLOSURE Indoor lighting fixture provides semi- indirect symmetrical light distribution. The fixture comprises a central support tube attached to the ceiling at its upper end and having a high intensity gaseous discharge lamp at its lower end projecting into a boxlike housing having a semi-transparent variable transmission lens on its bottom and an interior reflector extending around the lamp for reflecting light rays upwardly toward the ceiling. Vertically spaced louvers arranged encircling the upper portion of the lamp serve to shield the lamp from direct view of the room occupants to avoid glare.
