LIGHTING FIXTURE WITH SMOOTH ADJUSTABLE BEAM WIDTH |
摘要 |
A lighting fixture having a main housing to which is attached a moveable reflector assembly. The fluorescent lamps are affixed to the main housing and the moveable reflector assembly is adjusted to a position close to the fluorescent lamps to achieve a narrow illumination field. Adjusting the position of the moveable reflector assembly away from the fluorescent lamps achieves a wide illumination field. The reflector is designed as a near parabolic like shape and may be configured a s a single fluorescent lamp cavity, or a multiple lamp cavity wherein the parabolic like shapes for each fluorescent lamp intersect to provide a uniform illumination light field and highly efficient light output while minimizing the lighting fixtur e width. |
