Problems solved by technology

As a result, displays, especially displays, are difficult to read just under poor lighting conditions
These displays often have to be mounted where little light is available, where reading of the display often becomes difficult and uncomfortable
[0005] Powering the display of the measuring device poses difficulties because the measuring device is usually used in a remote location without power supply

Abstract

The invention relates to a lighting arrangement for a field device display. Said lighting arrangement comprises a circuit arrangement for a field device, comprising a power metering device, a power distribution device and a lighting device. The power metering device and the power distribution device are adapted to determine an existing power and to transmit excessive power to a display lighting control device. Said display lighting control device determines whether the existing power is sufficient for lighting and controls a lighting device if there is sufficient power. The lighting device comprises a light distribution device and a light generation device.

Description

[0001] related application [0002] This application claims priority to US Provisional Patent Application 60 / 754,471, filed December 27, 2005, and German Patent Application 10 2005 062419.7, filed December 27, 2005, the contents of which are hereby incorporated by reference. technical field [0003] The invention relates to a circuit arrangement for a field device, a lighting device for a field device display module, a lighting device for a field device display, a method for activating a lighting device for a field device display, A computer-readable medium with a program for activating a luminous means of a field device display and a program element with a program for activating a luminous means of a field device display. Background technique [0004] Typically, display devices or displays for reading measured values ​​of field devices, sensors or measuring devices have a low contrast ratio relative to the surroundings. As a result, displays, especially displays, are diffi...
