Abstract
An LED light bulb device including a bulb body, a cap, an LED assembly, and first and second light affecting features. The cap is mounted to the bulb body for connection to an electrical socket. The LED assembly includes a plurality of LEDs and framework. The framework maintains the LEDs relative to the bulb body such that emitted light is directed at an LED region of the wall. The first light affecting feature is associated with the LED region of the wall, whereas the second light affecting feature is associated with a diffusion region of the wall, with the diffusion region being apart from the LED region. The first light affecting feature affects light in a manner different from that of the second light affecting feature. The light affecting features are selected to affect or alter light emitted from the LEDs to provide a desired Kelvin color temperature and diffusion.
