Abstract
The embodiments of a light-emitting-diode-based (LED-based) light bulb and an LED assembly described provide mechanisms of reflecting generated by LED emitters toward the back of the LED-based light bulb. An upper substrate and a lower substrate are used to support upper and lower LED emitters. A slanted and reflective surface between the upper substrate and the lower substrate reflects light generated by the lower LED emitters toward the backside of the LED-based light bulb.
