Abstract

A light-emitting diode (LED) lamp for producing a biologically-corrected light. In one embodiment, the LED lamp includes a color filter, which modifies the light produced by the lamp's LED chips, to increase spectral opponency and minimize melatonin suppression. In doing so, the lamp minimizes the biological effects that the lamp may have on a user. The LED lamp is appropriately designed to produce such biologically-correct light, while still maintaining a commercially acceptable color temperature and commercially acceptable color rending properties. Methods of manufacturing such a lamp are provided, as well as equivalent lamps and equivalent methods of manufacture.
