LED LAMP OF INCANDESCENT-TYPE HIGH EFFICIENCY IN HEAT RADIATION

摘要

PURPOSE: An incandescent-type LED lamp having excellent cooling efficiency is provided to extend the lifecycle of the LED greatly by rapidly and effectively radiate the heat of the LED from a metal circuit substrate and ceramic layer. CONSTITUTION: A light diffusion lens(20) is combined to a front end of an insulation finishing cap(10) having a socket combining unit(11). An additional light diffusion lens(30) formed as aspherical is combined to an inner side of the light diffusion lens. A circuit substrate(50) having the LED is combined in the inner side of the light diffusion lens.
