The traditional airport navigation aid lamp generally takes a halogen tungsten lamp as a light source, the halogen tungsten lamp emits light in a 4 pi solid angle in the whole space, and the airport navigation aid lamp only needs two sides of light in opposite directions, so that the light utilization rate is low. Meanwhile, the light efficiency of the halogen tungsten lamp is low, about 15-20lm/W, and much energy is wasted. And the service life of the halogen tungsten lamp is only 1500 hours, and the light source needs to be replaced once in 5-6 months at the airport, so the cost is high.
The LED light source is a lighting light source with good monochromaticity, high illumination efficiency and low cost, the airport navigation light adopting the LED as the light source generally selects the color of the LED light source according to the color of light required to be used, and when yellow light is required to be generated, the yellow LED light source is generally directly used. However, the yellow LED light source has a relatively low luminous efficiency, and the luminous flux decreases significantly with the increase of the junction temperature (the luminous flux at 70 ℃ is only 50% of that at 25 ℃), which does not satisfy the requirement of the airport navigation lights for yellow light.
