PURPOSE: An LED lamp with improved light efficiency is provided to improve energy efficiency and heat dissipation by supplying high illuminance using a small amount of energy. CONSTITUTION: A heat sink is formed on the outer surface of a body(110) and is made of metal materials with high thermal conductivity. An LED substrate(120) is positioned on the upper side of the body. One or more LEDs(121) are mounted in the center of the LED substrate. A cap(130) covers the LED substrate on the upper side of the main body. A light efficiency improving lens unit(140) is installed between the cap and the LED substrate and collects light emitted from the LED. The light efficiency improving lens unit includes a transparent light efficiency improving lens(141), a first fixing holder(142), and a second fixing holder(143). |
