Efficient lighting system with wide color range

A lighting system, comprising:

• at least one remote phosphor LED comprising:
• a pump LED propagating light toward a dichroic reflector, and
• a phosphor layer structurally separated from the pump LED and optically coupled thereto, wherein the dichroic reflector:
• substantially reflects a first portion of excitation light emitted by the pump LED toward the phosphor layer to cause the phosphor layer to generate phosphor light, and transmits the phosphor light through the dichroic reflector to produce transmitted phosphor light, and
• substantially transmits a second portion of the excitation light emitted by the pump LED to produce transmitted excitation light, wherein the pump LED and the phosphor layer are arranged such that the second portion of the excitation light does not pass through the phosphor layer;
• at least one direct emitting short wavelength LED emitting short wavelength light with a peak output wavelength of 400 nm to 500 nm;
• at least one direct emitting long wavelength LED emitting long wavelength light with a peak output wavelength of 600 nm to 700 nm;
• a light-transmissive cover member overlying the at least one remote phosphor LED, the at least one direct emitting short wavelength LED, and the at least one direct emitting long wavelength LED;
• and
• a control system configured to drive portions of the at least one remote phosphor LED, the at least one direct emitting short wavelength LED, and the at least one direct emitting long wavelength LEDs independently such that the transmitted phosphor light, the transmitted excitation light, the short wavelength light, and the long wavelength light propagate toward the light-transmissive cover member and are transmitted therethrough to produce a broadband output light from the lighting system.
