Beschreibung
Zusammenfassung:	A light emitting element control circuit and power supply for a solid state lamp includes an electrical control circuit controller which enables the operation of a solid state lamp in three distinct modes, which allows the user significant flexibility in operation of the lamp. It enables the user to operate the lamp with a fixed emission spectrum but with intensity control (Mode I); or with discrete settings of blue only or red only or a fixed ratio of the two (Mode II); or an on-demand ratio of blue to red emission whereby the user can operate the lamp with any arbitrary ratio of blue to red for example to meet different spectral requirements of, for example, different phases of plant growth (Mode III).
