摘要： A lighting apparatus includes a bilaterally symmetrical light engine comprising first and second light emitting diode (LED) devices or planar LED device arrays facing opposite directions, and an envelope including phosphor spaced apart from and surrounding the bilaterally symmetrical light engine. The phosphor is effective to convert light emitted by the light engine to emission light. The bilaterally symmetrical light engine may be configured to emit light having a bilaterally symmetrical intensity distribution that is uniform except at emission angles within 10° of the symmetry plane of the bilaterally symmetrical light engine. Each of the first and second LED devices or planar LED device arrays may comprise at least one hemispherically emitting LED device including an LED chip and an encapsulant encapsulating the LED chip and shaped to refract light emitted by the LED chip into a uniform distribution over a hemispherical solid angle.

摘要： A signal is described that includes one or more LEDs that emit light and a lens that receives and collimates the light from the LED array. A distribution optic receives light from the collimating lens and distributes the light in a predetermined pattern according to a specification. A light absorbing/reflecting element is located in an area proximate the one or more LEDs to minimize light received from an external source from exiting the signal.
