Zusammenfassung:	An LED headlamp for attachment directly or indirectly to a user. Generally speaking, the disclosed headlamp includes an adjustable strap for securing to a user (e.g., head, arm, jacket, backpack, etc.), an LED array detachably securable to the adjustable strap, and a battery pack coupled to the LED array via an input power port. Preferably, the battery pack is rechargeable and is hardwired to the LED array. Optionally, the array may include a connection port that can accept any of several different power sources for powering the LED array of the headlamp, including a DC battery pack (e.g., AAA, AA batteries), a portable charger, an AC connection, to a wall outlet, and a computer USB charging connection. Further, the LED array may include a range of from 4 to 30 LEDs; more preferably, the number of LEDs is in the range of from 8 to 20. The LEDs should be spaced to provide a broadband of illumination, as opposed to a focused beam. The resulting illumination arc is at least 120 degrees, preferably at least 180 degrees, and most preferably about 210 degrees.
