Light emitting diode light bulb having a light dispersing layer attached on an envelope thereof

摘要

An LED light bulb includes a holder for electrically connecting with a power source, an LED mounted on the holder, an envelope mounted on the holder and covering the LED, and a light dispersing plate attached to an inner surface of the envelope. The light dispersing plate is made of a transparent material with a plurality of irregular air bubbles therein. Light generated by the LED and radiating to the envelope is refracted, reflected and scattered by the bulbs before the light emits out of the LED light bulb.
