Abstract

A LED coaxially-combined light engine and a lighting fixture therefor. The LED coaxially-combined light engine (100) comprises: at least two concentric, circular LED light engines (101, 102, 103) disposed, from large to small, one on the other. Each concentric, circular LED light engine (101, 102, 103) comprises: (i) an annular light guide plate having triangular positioning prisms, said light guide plate comprising a smooth surface (111) and a prism surface (112), said prism surface (112) being provided with multiple concentric, ring-shaped micro-prism structures; the distance between the smooth surface (111) and the top points of the triangular cross-section of each ring-shaped micro-prism gradually increasing from the inner ring of the light guide plate to the outer ring thereof; and an annular groove being provided near the outer ring of the light guide plate; and (ii) a LED ring-shaped light source (113), said light source (113) being arranged in the annular groove of the light guide plate and comprising a PCB and LED chips (122) attached to the PCB at equal intervals.

Description

technical field [0001] The present application relates to an LED light engine, in particular to an LED coaxial combined light engine and a lighting fixture using the LED coaxial combined light engine. Background technique [0002] Compared with traditional light sources, LED lighting has the characteristics of small size, energy saving, long life, high brightness, and environmental protection. In the field of lighting, the application of LED light-emitting products is attracting the attention of the world. As a new type of green light source product, LED must be the trend of future development. The 21st century will enter the era of new lighting sources represented by LEDs. [0003] In the PCT international application with the application number PCT / CN2008 / 001534 submitted by the applicant of the present application on August 26, 2008, a circular reflective plate with an equal cross-section triangular directional prism and a circular plate made of it are disclosed lamp.
