A condensing lighting device is provided to improve optical focusing efficiency by arranging a plurality of LED(Light Emitting Diode)s in a cylindrical body. A condensing lighting device(100) includes a main body(110), an optical source, a cone reflecting unit(112), and a condenser lens(140,150). The main body has a hollow cylindrical shape. The optical source is arranged in an inner surface(120) of the main body. The cone reflecting unit is arranged in one side of the main body. The cone reflecting unit reflects the light radiated from the optical source to the other side of the main body. The cone reflecting unit is protruded to the inner part of the main body. The optical source includes a plurality of LED substrates(116) and a plurality of LEDs(118). The plurality of LED substrates are extended to the axial direction of the main body. The plurality of LED substrates are arranged along the circumference direction of the inner surface of the main body. The plurality of the LEDs are mounted on respective LED substrate. The condenser lens controls the progressing path of the light reflected from the cone reflecting unit to the main body. |
