Abstract:
An illuminating filter which provides both clean air and light to a particle controlled environment. The integration of filtration and lighting simplifies the design of cleanrooms, mini-environments, and clean zones. Space savings and cost savings are served by combining filtration and lighting into a single structure. Light emitters, such as LEDs or other solid state devices, may be used where low voltage or low current is desirable.
