Design of one novel LED airport runway centerline light suitable for various applications

摘要

Compared with traditional aviation ground runway lights, such as halogen lamps with low optical efficiency and poor color rendering index, LED have superior performance and begins to replace the halogen lamps to become the main aviation ground lamps. For aviation ground midline light require yellow or green light, we can choose a type of green or yellow LED to substitute the halogen lamps to achieve specific color light with high luminance and low power consumption for no color filtering from white light. The light intensity of midline lamps specified by National Transportation Safety Board cannot be satisfied by usual LED lamps. A new aviation ground taxiway midline light is made with freeform lens and new mechanical structure called angle adjustment plate. By our simulation, the new aviation ground taxiway midline light can be applied in different light intensity distribution requirement circumstance of aviation ground midline lighting.
