LIGHT SOURCE UNIT AND LUMINAIRE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a light source unit which makes the efficiency of radiation to an illumination space less likely to deteriorate while reducing glare.SOLUTION: A cover 6 is formed into a box shape by a front surface part 600 facing a light source and a side surface part 601 which protrudes from a periphery of the front surface part 600 to the light source side in a direction perpendicular to the front surface part 600 and is arranged so as to cover the light source. In the cover 6, first crepes 6002 are formed on an inner surface of the front surface part 600 and second crepes 6011 are formed on an inner surface of the side surface part 601 so that light diffusibility of the front surface part 600 becomes higher compared to that of the side surface part 601.SELECTED DRAWING: Figure 7
