SOLID STATE CONTINUOUS SEALED CLEAN ROOM LIGHT FIXTURE |
摘要 |
A clean room ceiling light fixture (10) formed as a sealed housing (12, 14, 16, 18, 20) with a downwardly-directed light emitting aperture (36). A heat sink (22) fixed within and spaced from the housing defines a cable raceway (24). LEDs (26) are mounted on the heat sink. A high refractive index reflector (30) coupled to each LED efficiently directs light into the clean room. An anti-reflective coating (38) on the LEDs and/or reflectors improves light transmission efficiency. A refractive index matching compound (46) applied between each LED-reflector pair further improves efficiency. A spectrally selective filter material prevents ultraviolet illumination of clean rooms used for processes compromised by ultraviolet rays. A holographic diffusion lens (52) and/or variable transmissivity filter (54) can be provided to uniformly distribute the LEDs' light. The fixture can be sized and shaped for snap-fit engagement within an H-Bar type clean room ceiling. |
