Abstract
A bulb-type LED lamp () has a bulb () mounted on a socket (). A light source (), comprising a plurality of LEDs mounted on a PCB (), is arranged inside the bulb (). The PCB () acts as and/or is connected to cooling means (). The outer surface () of the bulb is formed both by light transmittable surface () and/or sub-areas () thereof and the cooling means (), which cooling means extend from inside the bulb into the outer surface of the bulb. Surfaces are mutually flush at locations at the outer surface of the bulb where said surfaces of both the cooling means and the light transmittable sub-areas border each other. The spatial light intensity distribution of the lamp of the invention is significantly improved over the prior art bulb-type LED lamp.
