LED LIGHTING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an LED lighting device which inhibits or prevents illuminance unevenness resulting from heat expansion of a reflection member.SOLUTION: An LED lighting device includes: an LED substrate 1 on which LED elements 10 are disposed; a base 2 to which the LED substrate 1 is attached; a cylindrical reflection member 4 surrounding the LED elements 10; and an outer cylinder 5 serving as a support member supporting the base 2. The reflection member 4 is supported by the outer cylinder 5 serving as the supporting member and separated from the LED substrate 1.SELECTED DRAWING: Figure 4
