PROBLEM TO BE SOLVED: To provide a lighting device capable of increasing an amount of light in a lateral direction almost parallel to a light-emitting face.SOLUTION: A cover 30 has a hemispherical shape and its central part 32 is arranged to oppose to a light-emitting face 31 of an LED module 3. The LED module 3 is mounted on a protruded part 41 making a protruded step arranged at a central part of an LED plate 4. Around the LED module 3, there is arranged a reflection face 22 for reflecting light of the LED module 3 reflected in an inner side face of the cover 30 toward the cover 30 again. In a reflection member 2, the shorter a separated dimension from the LED module 3 is, the larger against the light-emitting face 31 of the LED module 3 an inclination angle of reflection face 22 is. |
