Runway light for airport

Abstract

The invention relates to a runway light for an airport. The runway light for the airport comprises a housing component and a light source and a lens component arranged in the housing component, wherein the lens component comprises a first lens and a second lens; the first lens comprises a first incident plane, a second incident plane and a first ray exit surface; the light source is aligned with the first incident plane and the second incident plane; included angles are formed between the first incident plane and the second incident plane and the plane perpendicular to the optical axis of the light source and are symmetrical around the plane perpendicular to the optical axis; the second lens is mounted on the first ray exit surface and comprises a third incident plane and a second ray exit surface; light emitted by the light source refracted by the first incident plane and the second incident plane is scattered and irradiated to the second ray exit surface through the first ray exit surface and the third incident plane, and is refracted on the ray exit surface to form a gathered light which is ejected.

Description

technical field [0001] The invention relates to the field of lighting, in particular to an airport runway light. Background technique [0002] Airport runway lights are used as airport navigation lighting fixtures, which are lighting equipment installed along both sides of the airport runway and at both ends of the runway to indicate the position and range of the runway. According to different installation methods, these runway lights are divided into vertical lights and recessed lights, and most of them use traditional halogen lamps as light sources. In actual use, most of these runway lights use reflectors to gather light. However, the existing airport runway lights have the following disadvantages: (1) The structural size of the reflector is often large, which will occupy a large installation space, resulting in an increase in the overall size and production cost of the runway lights; (2) The reflectivity of the reflector is relatively low, generally only about 80%, whic...

AI Technical Summary

Problems solved by technology

However, the existing airport runway lights have the following disadvantages: (1) The structural size of the reflector is often large, which will occupy a large installation space, resulting in an increase in the overall size and production cost of the runway lights; (2) The reflectivity of the reflector is low, generally only about 80%, resulting in a large loss of light energy and a low utilization rate of light energy

Therefore, the existing runway lights cannot meet the actual needs, especially the needs of special-purpose airport runways (such as military airport runways)
