PROBLEM TO BE SOLVED: To provide a luminaire keeping excellent heat radiation performance of an LED, without impairing a characteristic of an electric component such as an illuminance sensor IC mounted on the same substrate as the LED.SOLUTION: A luminaire comprises: two LEDs 101A, 101B used as a lighting device; an illuminance sensor IC 102A detecting the light and shade of external light; a chip resistance 102B being a peripheral component of the sensor; a chip capacitor 102C; a connector 102D electrically connected an LED drive substrate; a mounting substrate 103 mounted with each components; a heat radiation member 106 directly contacting with the mounting substrate 103 and having four opening parts 104A-104D; and two machine screws 105A, 105B for attaching the mounting substrate 103 to the heat radiation member 106.SELECTED DRAWING: Figure 1 |
