The aircraft landing signal lamp is a kind of optical equipment which provides the pilot with visual landing optical indication. It is installed on the apron of the airport. The aircraft landing signal lamp is usually installed on the aircraft landing sign line. To ensure the safety of aircraft taking off and landing, the height of the lamp after installation should not exceed 30mm. Aircraft landing lights need to provide 360 degrees of horizontal direction, 7 degrees to 90 degrees of vertical direction, and the power should not be too large, therefore, the optical system is required to have a reasonable light distribution curve, high light utilization rate. Because pilots are equipped with night vision equipment at night, landing lights need to provide a near-infrared light signal as well as visible light. To make aircraft take off and land safer, this paper designs an optical system of aircraft landing signal light based on the principle of light guiding optics, which makes the upper surface of the lamp flush with the mounting surface. The height of the lamp after installation is 0mm. The optical system consists of LED integrated surface light source and light guiding glass column. Integrated surface light source integrates visible light LED chip and near infrared LED chip together. To make the light Angle larger and the light distribution curve more reasonable, the upper surface of the light guide glass column is in the form of microlens array. At the end of this paper, a photo of the optical indication effect of aircraft landing signal light is given.
