LIGHT SOURCE UNIT AND LIGHT FITTING USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a light source unit which reduces costs for changing distribution of light radiated from light emitting elements, and to provide a light fitting using the light source unit.SOLUTION: An LED chip 210 is mounted on one surface of a substrate 21. A lens 22 is disposed so as to cover the LED chip 210 and controls distribution of light radiated from the LED chip 210. The substrate 21 and the lens 22 are attached to an attachment member 23. The attachment member 23 includes: a base part 231; ribs 2323 to 2326; and fixing parts 2314 to 2317. The base part 231 has a plate shape and the substrate 21 is attached thereto. The ribs 2323 to 2326 protrude in a thickness direction of the base part 231 and the lens 22 contacts the ribs 2323 to 2326 in a state where the lens 22 is attached to the attachment member 23. The fixing parts 2314 to 2317 sandwich the lens 22 with the ribs 2323 to 2326 in a thickness direction of the base part 231 to fix the lens 22 to the attachment member 23.SELECTED DRAWING: Figure 1
