Abstract

The invention relates to an airport taxiway sidelight, which comprises an LED light source, a light condensation and reflection cup, a prism and a concave lens. The prism is provided with a light entrance surface, a fully reflecting surface, a first light exit surface and a second light exit surface, wherein the first light exit surface is arranged around the second light exit surface; the first part of light emitted by the LED light source can enter the prism through the light entrance surface after being reflected by the light condensation and reflection cup and then form illuminating light covering 360 degrees in the horizontal direction and 0-6 degree(s) in the vertical direction from the first light exit surface after being reflected by the fully reflecting surface; and the second part of light emitted by the LED light source can enter the prism directly through the light entrance surface, exit from the second light exit surface of the prism and then form illuminating light covering 15-90 degrees in the vertical direction after being diffused by the concave lens. The invention can satisfy the light distribution requirements of the embedded taxiway sidelight that the light can be emitted within 360 degrees in the horizontal direction, the light intensity is higher than or equal to 2cd within 0-6 degree(s) in the vertical direction and the projected light within 15-90 degrees in the vertical direction is visible.

Description

technical field [0001] The invention relates to the field of airport navigation lights, in particular to an improvement of a light distribution system for embedded taxiway edge lights at airports. Background technique [0002] The existing embedded taxiway side lights used in airports mostly use halogen tungsten lamps as light sources, such as 48W halogen tungsten lamps, and then filter through filters to obtain the required monochromatic light, such as using blue filters for filtering , to get blue light. Airport taxiway edge lights using this light source have high power consumption, short service life, and high use and maintenance costs. Moreover, because the required monochromatic light needs to be obtained by using a filter, the structure of the lamp is complicated, and the light efficiency of the light source is reduced. [0003] At present, the increasingly widely used LED light source has better anti-vibration performance, longer life and lower energy consumption t...
