摘要： A LED lamp has at least two LEDs to provide light of at least two different spectral outputs. An optic element has an entry surface disposed to receive the light from the LEDs. The entry surface includes refracting surfaces that refract the light tangentially. The refracting surfaces may extend radially relative to a center of the entry surface. The refracting surfaces may be continuously curved in cross-section where the refracting surfaces may include convex refracting surfaces and concave refracting surfaces.

摘要： A solid-state lamp with an angular distribution optic is disclosed. Embodiments of the present invention can provide for improved luminous intensity distribution in the vertical plane for a vertically oriented solid-state lamp. A lamp according to some example embodiments of the invention includes at least one LED, an optically transmissive enclosure for the LED or LEDs, and a base. The lamp also includes a distribution optic conformably disposed in or on the base to conduct light for angularly distributed emission from the base of the lamp. In some embodiments, the lamp is dimensioned as a replacement for a candelabra type incandescent bulb. The distribution optic can be composed of any optical medium, and in some embodiments, may be from about 1 mm to about 5 mm thick. In some embodiments, the distribution optic is made of thermally conductive plastic.
