Abstract
Description
Technical Field
[0001] This utility model mainly relates to the field of landing light technology, specifically to an aircraft landing light of the combined lens type. Background Technology
[0002] Aircraft landing lights are important external lighting equipment for civil aircraft, providing sufficient light for safe nighttime landings. When an aircraft lands at night, the landing lights illuminate the landing area, allowing the pilot to clearly visually assess the aircraft's relative position to the runway and its altitude, thereby safely maneuvering the aircraft for landing and taxiing, ensuring a safe landing.
[0003] Currently, the effective scattering angle requirements for LED aircraft landing lights vary, and different aircraft have different angle requirements. Custom lens molds are expensive and have long processing cycles, making them less economical.
[0004] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content
