Lighting device, the luminaire is provided with an LED light-emitting device, a radiator connected with the LED light-emitting device, and a light gathering part used for controlling the orientation to be within a range narrower than the light distribution of the LED light-emitting device. The radiator is provided with a bottom plate and a plurality of column-shaped or flat-plate-shaped heat conduction components. Wherein one tail end of the heat conduction part is connected with the bottom plate, the LED light-emitting device is arranged in the center area of the bottom plate, and tc/te is larger than or equal to 1.2 when the maximum thickness of the center area of the bottom plate is set to be tc and the minimum thickness of the peripheral area of the bottom plate is set to be te.
