光源投影线定义活动区域

Light source projecting lines defining activity area
Abstract:
A lighting system, for use in combination with a basketball backboard device mounted on a pole, comprises a plurality of lighting devices positioned adjacent the basketball backboard device. The lighting devices comprise a housing, a connector, a first light source, a lens and a light filter, and a secondary light source. The lens focuses lines defined by the light filter. The first light source is positioned to project the lines on to an activity surface to define a foul lane for a basketball court. The connector connects the housing to the pole supporting the basketball backboard device. The secondary light source is positioned to simultaneously illuminate a backboard of the basketball backboard device while the first light source projects the lines through the lens and the light filter. The lines from the first light source combine together on the activity surface to define an area for a basketball game.
