Abstract: An LED lighting apparatus includes an LED light-emitting unit, a radar detector, a controller, and a translucent cover. The LED light-emitting unit has a plurality of LED chips. The radar detector transmits radio waves, receives radio waves reflected by an object, and detects a movement of the object based on a change in a wavelength of the received radio waves. The controller controls light emission of the LED light-emitting unit based on a result of the detection by the radar detector. The translucent cover covers the LED light-emitting unit in a main emission direction in which a center of the light emitted from the LED light-emitting unit travels, and allows light from the LED light-emitting unit and the radio waves from the radar detector to pass through. The radar detector is surrounded by the LED light-emitting unit in the main emission direction.
