Abstract:
LED components are described having primary optics providing improved LED component emission characteristics. Light fixtures are also described that utilize the LED components to provide improved light fixture emissions. One LED component (30) according to the present invention comprises an LED chip (34) emitting an LED chip emission pattern. A primary optic (36) is included directly on the LED chip with LED light from the LED chip passing through the primary optic. The primary optic shapes the LED emission pattern into an LED component emission pattern with the LED component emission pattern being broader than the LED chip emission pattern.
