摘要：
An LED lamp comprising a housing, a drive circuit, LED dies driven by the drive circuit, and an output-select controller to program the drive circuit to drive the LED dies in one of a pre-sleep configuration and a general lighting configuration. The LED dies comprise LED dies of a first spectral output having a peak wavelength between 500 nm and 600 nm and of a second spectral output having a peak wavelength greater than 600 nm, first blue LED dies having a peak wavelength between 420 nm and 480 nm, and second blue LED dies having a peak wavelength below 420 nm. The drive circuit operates each of the LED dies of the first and second spectral outputs and the second blue LED dies in the pre-sleep configuration, and the LED dies of the first and second spectral outputs and the first blue LED dies in the general lighting configuration.
