Abstract
A lighting arrangement for a field unit screen is provided. The lighting arrangement comprises a circuit arrangement for a field unit with a power measuring device, a power distribution device, and a luminous device. The power measuring device and the power distribution device are adapted for determining an existing power and forwarding a surplus power to a screen light drive device. The screen light drive device determines whether the existing power is sufficient for lighting, and drives a luminous device when sufficient power is available. The luminous device comprises a light distribution device and a light generating device.
