Head lamp

摘要

A head lamp assembly wearable by a user or attachable to an object comprising a substrate, a first light source, a second light source, and a sensor. The sensor can turn the first and second light sources ON when light striking the sensor falls below a predetermined intensity level. The sensor can turn the first and second light sources OFF when light striking the sensor exceeds a predetermined intensity level. An override switch can allow user to keep the light sources either completely illuminated or obfuscated, irrespective of the sensor.
