  • an embedded beacon lamp embedded in a runway, taxiway or road at an airport must emit a predetermined emission light on the runway to ensure aircraft safety. For example, when ice or snow adheres to the light projection window of the embedded marker lamp and does not melt, it becomes impossible to emit predetermined outgoing light from the light projection window.
