Portable Lamp Comprising an Improved Locking Mechanism

摘要

A headlamp with a light source, an electrical power source and several states controlling power sources and light beams is presented.;The first state corresponds to at least one activated state in which the electrical power source is coupled to a light source to generate a light beam.;The second state corresponds to a deactivated state where the electrical power source is not coupled to a light source and no light beam is generated.;The third state corresponds to a locked state in which the electrical power source is not coupled to a light source and no light beam is generated;;Also included is a switching mechanism to receive a first and a second physical user input through one switching element. A processor is coupled to the switching mechanism and is used to select one among the first, second and third states in response to the physical user inputs.
