Design of Energy Efficient Recessed Compact Fluorescent (CFL) Downlight Fixture Dr. Raju Dandu, Associate Professor Mechanical Engineering Technology Kansas State University at Salina

Abstract

A recessed downlight is designed to address limited availability of energy efficient residential and light commercial recessed downlight fixtures. This fixture is a non-conventional indoor insulated ceiling (IC) rated, air-tight recessed compact fluorescent lamp (CFL) downlight fixture. The distinct features of fixture include: compact and light weight, unique CFL lamp, built-in- modularity and high lumen output. This paper outlines the design and development of a recessed downlight to address the early market acceptance of CFL fixtures and the replacement of incandescent light sources.

Introduction

United States Government agencies and electric utilities are actively promoting the market transformation of energy efficient residential light fixtures. A major impediment to these promotions is the lack of performance and affordable price of these light fixtures. Given the market size and the number of “off the shelf” technology solutions, Department of Energy (DOE) sees a significant opportunity to improve the energy efficiency of recessed CFL downlights. There is a dire need to develop a CFL downlight that will effectively resolve the existing issues of competitive cost, high lumen output, and performance problems due to high temperatures.

Background of Product Development

The barriers to successful commercial introduction and early market acceptance of recessed compact fluorescent lamp (CFL) downlights are known. Ecos Consulting, Benya Lighting Design, Rising Sun Enterprises (2002) market research report stated that the barriers are:

relative high price limited market availability limited high lumen output performance problems such as reduced lumen output, lamp life, and ballast life from high temperatures lack of easy access for component replacement

Improvements in CFL technology, innovative designs, manufacturing, and distribution can reduce or minimize several of these barriers. A less expensive, efficient and attractive with improved quality, a properly designed recessed CFL downlight fixture can resolve the above concerns and there by can significantly influence acceptance of market penetration over incandescent recessed downlight fixtures. If the recessed CFL downlight is well designed,
