Airport taxiway side light

Abstract

The invention relates to an airport taxiway side light which comprises a shell with an opening on the top end and a light transmission piece connected with the opening end of the shell, wherein the shell and the light transmission piece form an inner cavity together, a circuit board and a light source are arranged in the inner cavity, the light source comprises a light source locating cover and aplurality of light source units, wherein the light source locating cover is fixed above the circuit board and provided with a plurality of grooves which penetrate through the flange along the peripheral wall, a flange is arranged at the bottom of the light source locating cover, the plurality of light source units are respectively located in the grooves of the light source locating cover, and thelower end of each light source unit is electrically connected with the circuit board after passing through the flange. In the airport taxiway side light, a plurality of luminophors are arranged on a single circuit board monomer, and a plurality of circuit board monomers are arranged surrounding the circumference of the light source locating cover, thereby realizing 360 degree omnidirectional illumination, supplying uniform light spots and solving the problem of illumination blind spots.

Description

technical field [0001] The invention relates to a lighting fixture, more specifically, to an airport taxiway edge light. Background technique [0002] On the edge of the taxiway of the airport or the boundary line of the heliport, there are taxiway edge lights that provide lighting instructions or warnings. According to the purpose of the airport, there are generally two types of existing taxiway edge lights, one is an embedded taxiway edge light, and the other is a vertical taxiway edge light. [0003] Among them, the embedded taxiway edge lights bury the entire lamp into the ground, and only the light-transmitting parts slightly protrude from the ground to provide lighting instructions or warning light. At present, airport taxiways at home and abroad basically use this kind of roadside lights, which can maintain the overall smoothness of airport taxiways. However, after this roadside light is damaged, it is difficult to maintain, and when it goes out abnormally, it canno...

AI Technical Summary

Problems solved by technology

However, this roadside light is only provided with one light source, which cannot achieve uniform lighting in all directions

In the case of setting up other adjacent roadside lights of the same type, it will receive the light irradiated by the adjacent lamps. According to the principle of light wave coherence, the light wave will be strengthened or weakened, and the illumination will be uneven, which will affect the illumination of the airport. , burying a safety hazard for the taxiing of the aircraft
