Abstract

The invention is applicable to lighting for navigation and provides an airfield runway LED center line light. The LED center line light comprises LEDs, convergence lenses and prisms, wherein the convergence lenses are used for collimating the light emitted by the LEDs into parallel light; and the prisms are used for regulating the paths of the parallel light to ensure the parallel light to emit by dispersing upward in an oblique manner along the horizontal direction. After the LED center line light is connected with the power, the light emitted by the LEDs is changed into parallel light by the convergence lenses and enters into the prisms, the parallel light exits through refraction after being reflected by the prisms and disperses upward in an oblique manner along the horizontal direction during exiting, thus meeting the light distribution requirement of the airfield lights on the airfield taxiway bend. With the LEDs as the light sources, the LED center line light has low energy consumption, good shake resistance, long life and low maintenance cost.

Description

technical field [0001] The invention belongs to the field of airport navigation lights, in particular to an airport runway centerline light using LEDs as light sources. Background technique [0002] The existing airport embedded taxiway curve centerline lights mostly use 48W halogen tungsten lamps as light sources, and then filter through various color filters, which have high power consumption, short lifespan, and high use and maintenance costs. In addition, tungsten halogen lamps are large in size, and their light distribution is mostly a large-angle coverage type of light distribution, and more light is irradiated outside the light distribution area, which may cause interference and affect navigation. SUMMARY OF THE INVENTION [0003] The purpose of the embodiments of the present invention is to provide an airport runway LED center line light that meets the light distribution requirements of airport taxiway curves, and aims to solve the problems of high power consumptio...
