Beschreibung
Zusammenfassung:	PURPOSE: An LED embedded type airfield lighting device using a half paraboloidal mirror reflector is provided to reduce upward light by cutting a paraboric mirror in half and to secure a light distribution curve suitable for the light angle rules of airfield lighting. CONSTITUTION: A hemispherical paraboric mirror reflector(10) which is cut along the central axis of a paraboric mirror is formed. The hemispherical paraboric mirror reflector reflects the light radiated from the center of a light source(20) with the angle of 0° to 135°. The light source is formed in the focus of the hemispherical paraboric mirror reflector and is horizontal to the optical axis. A prism(30) reflects the light reflected from the hemispherical paraboric mirror reflector. The entry face(31) of the prism is vertical to the optical axis.
