Abstract
An LED device has a cap containing one or more quantum dot (QD) phosphors. The cap may be sized and configured to be integrated with standard LED packages. The QD phosphor may be held within the well of the LED package, so as to absorb the maximum amount of light emitted by the LED, but arranged in spaced-apart relation from the LED chip to avoid excessive heat that can lead to degradation of the QD phosphor(s). The packages may be manufactured and stored for subsequent assembly onto an LED device.
