LED LIGHT SOURCE AND LED LAMP USING THE SAME

摘要

A high efficiency and high-power LED light source comprises an LED (21), a light collector for collecting light emitting from the LED (21), and a convergence lens (23). The light collector is a concave mirror (22). The convergence lens (23) is placed in front of the LED (21). The light emitting part of the LED (21) is placed at a focus of the concave mirror (22) and a focus of the convergence lens (23). An LED lamp using the light source comprises a shell (2) in which a number of high efficiency and high-power LED light sources are arranged closely.
