Abstract

1536269 Indicator lamps SIEMENS AG 14 Nov 1977 [16 Nov 1976] 47378/77 Heading F4R An electrical coupling device for use in mining comprises a housing 2 containing an electrical circuit 3 and one or more light sources, e.g. light-emitting diodes 4, mounted on the circuit, light from the sources passing along flexible light conductors 5 to lenticular heads 10 disposed in apertures 7 in the housing. The housing is filled with a casting resin 11. In an alternative arrangement the light sources are mounted in apertures in the housing and are connected to the circuit by flexible electrical conductors.
