である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to electric lights, and more particularly to providing a lamp envelope which is vacuum-tightly sealed and affixed to the lamp cap at one end, so that a current supply conductor passes from a contact on the lamp cap to the lamp envelope. extending through the sheathing wall to a light source arranged within the lamp envelope, a fuse being included in at least one current supply conductor within the space defined by the lamp envelope wall and the lamp cap; It relates to an electric lamp located inside a sealed tube made of electrically insulating material and filled with electrically insulating material.

全ではあるが、２個所の融着のため高価につく。 Such an electric lamp is known from British Patent No. 830360. In this known electric lamp, the fuse is contained in a glass tube filled with glass pellets or sand and fused at its ends to the current supply conductor. Although this fuse is reliable and safe, it is expensive because it is fused in two places.

る電灯を製造することができる。 Before attaching the lamp cap to the lamp envelope, a tube of glass or ceramic material, for example, is slid over the current supply conductor until it surrounds the fuse, and this tube is then filled with an electrically insulating material and fitted with a tight mass. The lamp according to the present invention can be easily and inexpensively manufactured by sealing both ends of the tube to the current supply conductor.

いて目につかない。つまり感知し得ない。 Numerous constructions of electric light fuses are described in the literature. Some of these are expensive while others are unreliable or unsafe. It has thus been proposed to fill the space defined by the lamp cap and the wall of the lamp envelope with cement, with the fuse embedded therein.
However, gaps are formed in the cement mass, through which the discharge arc formed during the melting of the fuse can flash against other current supply conductors or against metal parts of the lamp cap.
This is called a flashover. Due to the fact that the cement mass or agglomerate assumes its final form after the lamp cap has been arranged, these gaps are not visible in the finished lamp. In other words, it cannot be detected.

る。 However, in the electric light according to the present invention,
In order to surround the fuse on all sides, it is necessary to provide an insulating mass only locally. This insulating mass can be provided before installing the lamp cap so that the fuse can be completely surrounded in a controlled manner. Due to the fact that the fuse is surrounded by an insulating mass,
Generally no discharge arc is formed during fuse melting. If an arc forms so far, it remains inside the tube and quickly dissipates.
本考案による電灯の構造は、高出力のハロゲン

トは同時に電流制限器として作用する。 Although the lamp structure according to the invention is particularly suitable for heavy duty lamps, such as high-power halogen lamps, the structure can also be used for other halogen lamps. Thus, in electric lamps which have both a filament and a discharge arc, for example a high-pressure mercury vapor discharge arc, as the light source, the filament simultaneously acts as a current limiter.
