NON-MAGNIFIED LED FOR HIGH CENTER-BEAM CANDLE POWER

摘要

Light emitting diode components are disclosed that utilize a thin, substantially flat or undomed encapsulant in order to achieve the desired emission profile to increase luminance and/or center beam candle power. Some embodiments of the devices include encapsulants, which result in an apparent source image, which does not exceed 2× the source size. Different embodiments of the present invention can comprise different configurations of emitters within the component, such as monolithic chips. The LEDs can be wire bonded to a surface. This surface can be black, reflective or include a reflective coating. In some embodiments, conversion materials can be applied conformal to the LED.
