OMNIDIRECTIONAL LIGHT-EMITTING DIODE LIGHT BULB

摘要

An omnidirectional LED light bulb includes a lighting cover, a main body, and a base. The lighting cover includes upper and lower covers, which are coupled together through first and second coupling sections formed on the upper and lower covers to form a bottom-open cover. The upper cover has an interior surface including a plurality of concentric engraved circular patterns circling around a center of the upper cover. The first and second coupling sections are coupled together in a completely sealed manner. The main body includes a casing receiving therein a power module and coupled to the lower cover with a sealing ring interposed therebetween. The casing has a top on which a lighting plate including light-emitting elements is mounted and electrically connected to the power module. The base is coupled to the main body.
