Motor-driven head-moving spotlight for use in event- and stage technology for generating lighting- and projection effects, has aspherical lens that bundles light radiation of LEDs and is arranged at distance of three to six mm to LEDs

摘要

The spotlight has a metal blind, and a cooling body (1) with cooling power between 0.15 and 0.25 Kelvin/watt, where an LED chip (2) is directly attached on the cooling body. The cooling body carries 90 LEDs on a radiating surface with size of 3 to 6 square cm, where each LED has power of 1 to 3 watts. An aspherical lens (5) bundles light radiation of the LEDs, and is arranged at a distance of 3 to 6 mm to the LEDs, where diameter and height of the lens 40 mm and 20 mm, respectively. A phosphorus layer is provided in front of the LEDs.
