US Patent 7547125 Guard device for a light source

An embodiment of the present invention relates to the protection of electronic displays and includes a guard configured to protect a lighting means while providing an expanded field of view. The guard may include a first element and a second element each having at least a top surface and a wall. The lighting means may be positionable substantially between the first element and the second element such that the top surface of the lighting means is below the first top surface and the second top surface to protect the lighting means from incidental impact. A gap between the first and second elements provides a field of view. The field of view may include a substantially orthogonal line of sight to one side surface of the lighting means.
