Hybrid light bulbs using combinations of remote phosphor LEDS and direct emitting LEDS

摘要: A light source suitable for general lighting applications combines at least one remote phosphor LED and direct emitting in a single unit. Both the are carried by base covered bulb or other cover member, which may be light-diffusing. The includes first LED, layer, dichroic reflector. Excitation from is reflected reflector onto layer to generate light, substantially transmitted At some propagates member without passing through any reflector, including provide white output using relatively small amounts of material.
