摘要： This invention is a non-ferrous lighting fixture and non-ferrous lighting system that can be used in areas with high magnetic fields or that require low EMI emissions, such as MRI operating rooms. This invention uses LED's to provide a high-intensity, quality white or other color light that is softened by reflectors and diffusers, and can be dimmed to provide flexible lighting levels. The flexible lighting levels can range from the maximum light used for patient procedures and equipment servicing/maintenance to the lowest light level used to keep a patient comfortable while facing upward on the MRI scanning table. Moreover, by using an aluminum substrate printed circuit board, this invention resolves the thermal issues associated with high-intensity lighting. Not only does this invention resolve glare and hot spot issues, it protects the user and installer from electrical hazards associated with potentially high voltages, as well. Finally, because this invention is completely non-ferrous, it does not interfere with the integrity of the MRI equipment's readings.

摘要翻译： 本发明是一种有色金属照明灯具和有色金属照明系统，可用于具有高磁场或需要低EMI辐射的区域，如MRI手术室。 本发明使用LED来提供由反射器和扩散器软化的高强度，高质量的白色或其它颜色的光，并且可以被调暗以提供柔性的照明水平。 灵活的照明水平可以从用于患者手术和设备维修/维护的最大光线到用于在MRI扫描台面朝上时使患者舒适的最低光线水平。 此外，通过使用铝基板印刷电路板，本发明解决了与高强度照明相关的热问题。 本发明不仅可以解决眩光和热点问题，还可以保护用户和安装人员免受与潜在高电压相关的电气危害。 最后，由于本发明是完全有色的，它不会影响MRI设备读数的完整性。
