Disclosed is a lighting device of a photometry method using an LED. The lighting device of a photometry method forming a surface light source using the LED which is a point light source, comprises: an enclosure receptor having the LED installed on the side and formed with a reflector in the inside; a light reflecting structure provided on the bottom surface of the receptor to reflect the traveling direction of the light emitted from the LED to be substantially perpendicular; a light emitting control panel disposed to be separated from the light reflecting structure to adjust the amount of the emitted light; and a diffusion plate for diffusing the light emitted from the light emitting control panel. |
