Abstract: An airport runway approach lighting apparatus is disclosed. According to one embodiment, the airport runway approach light includes a visible light source configured to emit a visible light beam and an infrared light source configured to emit an infrared beam. A first lens is attached to the visible light source to change the visible light beam emitted from the visible light source to a desired visible light beam pattern. The infrared light source includes a plurality of semiconductor laser diodes distributed on a surface of a laser diode chip in an array.

Abstract: Disclosed herein is a heat generation apparatus using permanent magnets. The heat generation apparatus using permanent magnets includes: a plurality of rotors fixedly mounted on a rotating shaft, and configured such that they are rotatable along with the rotating shaft with permanent magnets disposed thereon at predetermined intervals; a heat generation part configured such that the rotors are contained therein to thus form a predetermined gap between the heat generation part and the rotors, and adapted to generate heat while the permanent magnets are being rotated; a motor configured to serve as a source for the rotation of the rotating shaft; and a power transmission means configured to transfer the rotation force of the motor to the rotating shaft.
