Runway center line light

Abstract

The invention relates to a runway center line light which comprises a light source, a reflector and a prism. The light source is arranged in the reflector; the prism comprises a light-in surface and a light-out surface which inclines with respect to the light-in surface; the light source is dead against the light-in surface; the rays of the light source converge onto the light-in surface through the reflector and are refracted out with deflection from the light-out surface; the angle between the light source and the ground is 53 degrees to 58 degrees; the distance between the light-out port of the reflector and the light-in surface is 19.5mm to 22.5mm; the refraction angle of the prism is 51 degrees to 56 degrees; and the size of the light-out port is 53mm X 42mm to 56mm X 45mm. The distance between the highest point of the light-out port of the light-out surface of the prism and the horizontal ground is less than 6.35mm, which satisfies the high requirements of airports. Therefore, the runway center line light can be applied in the airports with high demands to pilot the taking-off and landing of airplanes and thereby ensures safe taking-off and landing of the airplanes.

Description

【Technical field】 [0001] The invention relates to a lamp, in particular to a runway centerline lamp. 【Background technique】 [0002] The runway centerline lights are airport navigation lights, which are set on the centerline of the airport runway to guide aircraft takeoff and landing. [0003] At present, the specifications of runway centerline lights are mostly at or below the second-level standard. Since the highest point of the light is high, it is higher than the ground when it is installed on the runway, generally about 12 mm higher than the ground, causing a large protrusion on the runway. It can only be applied to ordinary airports, and cannot meet the light distribution and installation requirements of airports with high requirements (level 3 or above, less than 6.35mm above the ground), cannot be applied to high-demand airports, and cannot be used for aircraft take-off and landing at high-demand airports Guidance is carried out, so that the safe take-off and landin...
