Abstract

The present invention relates to an LED lamp in which a light-emitting optical sheet formed by processing a light-guide plate pattern on a prism sheet is placed within a cylindrical diffuser to ensure an emission angle of 360 degrees. The LED lamp according to the present invention comprises: a cylindrical diffuser for diffusing light; a light-emitting optical sheet which is placed within the cylindrical diffuser to ensure an emission angle of 360 degrees, and which is processed into a dot pattern on the back surface of the light-guide plate; and one or more LED modules which receive power from an external source via connection terminals so as to emit light into the cylindrical diffuser.
