Battery-powered lamp has control electronics that form light source control signal taking into account a measurement signal derived from battery voltage using stored relationship

摘要

The device has a battery compartment, at least one light source, a control stage between at least one battery and the light source and control electronics for driving the control stage to produce a constant light intensity until a defined and/or selected battery discharge state is reached. The control electronics form a control signal taking into account a measurement signal derived from the battery voltage using a stored relationship. The device has a battery compartment (5), at least one light source (2), a control stage (4) between at least one battery (6) and the light source and control electronics (8) for driving the control stage to produce a constant light intensity until a defined and/or selected battery discharge state is reached. The control electronics form a control signal taking into account a measurement signal derived from the battery voltage using a stored (9) relationship.
