METHOD AND APPARATUS FOR MAINTAINING CONSTANT COLOR TEMPERATURE OF A FLUORESCENT LAMP

摘要

A system to allow a fluorescent lamp to be dimmed or otherwise improve color performance of the lamp while maintaining a constant spectral distribution In one embodiment, the lamp will dim in light output and not shift in color temperature. An LED array is positioned under a fluorescent lamp such that its light injects back into the lamp that part of the color spectrum that diminishes as a fluorescent lamp dims The LEO array is positioned centrally along the underside of the lamp The light from the LED is never directly visible but shines through the lamp, the lamp acting as a diffuser The brightness level of the LEDs can be determined as a preset level relative to a predetermined dim setting or can be regulated through an electronic monitoring sensor
