Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a lighting device capable of efficiently deflecting light emitted from LEDs as compared with a conventional one.SOLUTION: The lighting device 1 is provided with inner lenses 13 arranged in front of LEDs 12 and an outer lens 14 arranged in front of the inner lenses 13 and the light from the LEDs 12 is deflected to the lower side. The inner lens 13 includes a first lens part 131 for deflecting the light around an optical axis Ax1 out of the light from the LED 13 to an advancing direction almost along a deflection direction, a second lens part 132 for deflecting the light advancing to the lower side than the first lens part 131 out of the light from the LED 12 to the advancing direction almost along the deflection direction, and a third lens part 133 for deflecting the light upward than the first lens part 131 out of the light from the LED 12 to the advancing direction almost along the deflection direction. The outer lens 14 includes lens cuts 140, ... which even light-advancing directions of the light from the firs lens part 131 to the third lens part 133.
