Abstract

The central electrode is mounted in a hollow elongated annular insulating body 24 of light conducting material which is secured in the metallic housing 23. The insulating body has at least partly unobstructed end surfaces and is at least in part of frusto conical shape converging in a direction away from the spark gap. The insulating body is formed or treated so that in operation substantially all the light entering thereinto at one of the end surfaces emerges at the other of the end surfaces only. The central electrode may be made of a semi-conducting material. At least one ground electrode 22 may be embedded in the insulating body and form a spark gap both with the central electrode and with the metallic housing. The insulating material may comprise axially extending light conducting fibres. The fibres may be glass fibres bonded together by a heat-resistant synthetic resin material. A surface discharge sparking plug is described.
