Device for illuminating the stope support at a longwall face

摘要

The light sources ( 13 - 15 ) for illuminating the stope support at a longwall face are operated at low voltage, connected to the control network device ( 8 ), for low voltage supply of the system controllers ( 1 - 7 ). LEDs are particularly suitable as light sources. Measures for avoiding an impairment of the function of the system controllers are disclosed.
