摘要:
SSL lamps or luminaires are disclosed that combine blue, yellow (or green) and red photons or emissions to generate light with the desired characteristics. In different embodiments according to the present invention, the blue emission is not provided by an LED chip or package having a blue LED coated with a yellow phosphor, with blue light leaking through the yellow phosphor. Instead, the blue light component can be provided by other types of LED chips in the SSL luminaire such as one having a blue LED covered by a different colored conversion material, with blue light from the blue LED leaking through the different colored conversion material. In one embodiment, the blue component can be provided by an LED chip comprising a blue emitting LED covered by a conversion material that absorbs blue light and re-emits red light, with a portion of the blue light from the LED leaking through the red conversion material.
