Abstract

A lighting device for use at a gas exhausting and/or gas feeding device at a work place, to illuminate said work place (2) can be ventilated efficiently while at the same time it is protected against splashes from the work place. The lighting device (9) comprises at least one halogen lamp and a light transmitting glass (11) provided at such a distance from said halogen lamp that an open space is defined between the halogen lamp and the glass, through which space heat from the halogen lamp can escape into the surroundings. <IMAGE>
