PROBLEM TO BE SOLVED: To provide a ceiling direct-mounted type LED lighting device in which a sensor is arranged with a simple configuration, which is configured so that the sensor is hardly affected by external light and which has good appearance.SOLUTION: An LED lighting device includes: an LED unit member 40 on which an LED element 40c and sensors 41, 42 are mounted; a reflector 60 arranged on an irradiation surface side of the LED unit member 40; and a translucent cover 70 arranged on the irradiation surface side of the reflector. The reflector 70 has a sensor accommodation part 60c for the sensors 41, 42 mounted on the LED unit member 40. The sensor accommodation part 60c has sensor window parts 60e, 60f on a surface part of the LED irradiation side, and a sensor window forming surface part is arranged so as to be on the substantially same plane as an irradiation surface 70a of the translucent cover. |
