Abstract:
1. A lighting apparatus comprising: a heat radiating body having a first heat radiating body, a second heat radiating body and a housing space inside the heat radiating body, and the housing space is defined by four inner walls and a top surface wall; a first substrate on which a first plurality of light emitting diodes (LEDs) are disposed in two lines on one side of the first substrate, the first LED module provided on a first one of the four inner walls of the first heat radiating body; a second substrate being disposed apart from the first substrate at a distance and including a second plurality of LEDs disposed in two lines on one side of the second substrate, the second LED module provided on a second one of the four inner walls of the second heat radiating body; a reflector being disposed between the first substrate and the second substrate, the reflector including a first surface that is inclined with respect to the one side of the first substrate and a second surface that is inclined with respect to the one side of the second substrate, the reflector to receive light from the first and second plurality of LEDs and to reflect the light in a light emission direction away from the top surface wall of the housing space and to outside of an opening of the heat radiating body, the reflector including a first locking part and a second locking part, and the first locking part and the second locking part to prevent the reflector from moving in the light emission direction away from the top surface wall of the housing space; and wherein the first LED module, the second LED module and the reflector are provided within the heat radiating body, wherein the light from the first plurality of LEDs is reflected by the first surface of the reflector in the light emission direction away from the top surface of the housing space and the light from the second plurality of LEDs is reflected by the second surface of the reflector in the light emission direction away from the top surface of the housing space.
