Lamp has lamp head designed as circuit board containing LED chains and current flowing in LED chains is constant

摘要

A lamp (10) has an electrical supply unit (11), a lamp body (12) and a supply line (13) from the supply unit to the lamp body. The lamp body has a lamp head (14) designed as a circuit board (15). The circuit board contains at least one LED chain (16) and the current flowing in the LED chain is constant. The lamp head designed as a circuit board has easily detachable electrical contact points (17). The circuit board of the lamp head has several parallel-connected LED chains. The electrical supply unit of the lamp is designed to be battery- or accumulator-driven.
