Abstract

The design purpose of general lighting apparatus is how to induce the illuminating direction of light source efficiently and provide people comfortable vision. The lighting device has a reflective area. However, the reflective light was often caused a glare and a light pollution. It causes eyes discomfort and eyestrain. This problem has been overcome by the novel device in this study. This paper proposes a novel LED light apparatus with innovative reflector type, designed to reduce the glare for light comfort. The apparatus is consist of a reflective wall with many circumferential micro-structured and a circumferential light source as plurality of LED. In addition, a Fresnel type reflector can replace the traditional convex reflector. Multiple LED light sources will be guided to the reflective wall and Fresnel type reflector with in device, so ray of light will be well spreaded and sufficiently directed to or focused on the desired area. The micro-structured reflection type will enhances the light illumination efficiency by applying appropriate design of micro-structured reflecting layer.
