Illuminated door lock, with LEDs, is switched on after dark to show the lock through light conductive materials

摘要

The door lock (200) is illuminated by a light emission. The light is from a LED (207) or a laser diode within the door panel, with light conductive materials carrying the light to various parts of the lock. Sensors (213) switch on the light when the ambient light falls and switches off when daylight returns.
