An object is to provide a lighting apparatus in which an LED does not look like a point optical source and which does not provide illumination with drastically reduced light intensity even in a place away from the LED and a place angularly deviated from the radiation direction of the LED, and in which a plurality of LED structures are arranged in parallel, utilizing the features of the LED such as having no heat, low power consumption, and long life. The problem is solved by use of the lighting apparatus which has an LED group (2) having a plurality of LEDs arranged in parallel and in which an elongated first light reflection member (3) having a cylindrical lens effect is provided on at least the front surface of the LED group. Further, the problem is solved by use of the lighting apparatus in which a plurality of elongated second light reflection members (13) having the cylindrical lens effect are arranged in parallel on at least the front surface of the LED group outside the first light reflection member in such a manner that the second light reflection member is substantially orthogonal to the first light reflection member. |
