LINEAR LIGHTING SYSTEM
First Claim
1. A light system for lighting a traffic surface, comprising a linear luminaire comprising a plurality of light sources disposed in a linear array along the length of the traffic surface, and a plurality of means for controlling and directing the emitted light perpendicular to the direction of the traffic surface and at an angle to the traffic surface.

Abstract
A linear light system, and a linear luminaire used in the system, for lighting a traffic surface. The linear luminaire has a plurality of light emitting diodes (LEDs) disposed in a linear matrix along the length of the traffic surface, and a plurality of refractive lenses for directing the emitted light from the LEDs at the traffic surface. The traffic surface is typically the roadway of a tunnel. A refractor lens is used to direct the emitted light from the LEDs predominantly toward at least the traffic surface.

5. A method for lighting an automotive tunnel having at least one tunnel wall wherein at least a portion of the tunnel wall has an exterior surface having a reflectance of at least 300%, comprising the steps of:
-
a. positioning a plurality of linear luminaries comprising a plurality of light sources arranged in a linear array, horizontally within the tunnel; and b. directing and controlling the emitted light from the plurality of light sources wherein at least 50% of the emitted light is directed at the exterior surface of the tunnel wall and reflects from the tunnel wall to the traffic surface. - View Dependent Claims (6, 16)

7. A luminaire comprising:
-
1) a light fixture that comprises; a. a linear light board comprising a plurality of light sources arranged in a substantially linear array along the length of the board, and b. a frame supporting the linear light board; 2) an elongated light-transmitting window having an inner surface and opposed first and second longitudinal sides; and 3) a housing having a base portion that supports the frame, and a pair of arms extending from the base, the distal end of each arm having a pocket with an opening for receiving the opposed longitudinal sides of the light-transmitting window, with the inner surface facing the base portion, wherein the distal ends of the arms can be biased away from one another for insertion of the longitudinal sides of the lens plate. - View Dependent Claims (8, 9, 10, 12, 13, 17)
