LED LAMP COVER WITH HIGH DIFFUSIBILITY AND TRANSMITTANCE

摘要

PURPOSE: A cover for an LED lamp with high diffusivity and transmittance is provided to illuminate indoors by efficiently diffusing light through repetitive lens unit. CONSTITUTION: A refractive surface(11) formed by a repetitive incline surface is formed on one side of a transparent cover(10). A lens unit(12,12') is formed on the other side of the cover. The lens unit of the cover is continuously formed. A convex sub lens unit(13,13') is arranged between the lens units. The sub lens unit connects the lens unit. The sub lens unit successively has the tilt angle of the opposite direction.
