Problems solved by technology

In addition, the lamp has the disadvantage of poor lighting quality when used in a reflector
That is, an undesired non-uniform brightness distribution due to the spatially extended and segmented helical filament

Embodiment Construction

[0028] Figure 1a with 1b A schematic side view and a view rotated by 90° of the high-voltage halogen incandescent lamp extruded at one end of the present invention for a 230 volt supply voltage are respectively shown. Electric power consumption and light efficiency are 1000 watts and 25 lumens / watt (1m / W) respectively.

[0029] The lamp has a bulb 1 made of quartz glass. One end of the bulb is made into a dome with a sealed exhaust head 2; and on the other end, the bulb 1 is welded by an extrusion seal 3. Like a general halogen incandescent lamp, the bulb 1 is filled with a well-known halogen. The filling components are, for example, xenon and nitrogen and a few percent of halogen, such as dibromide (DBM). The inflation pressure is about 3 bar.

[0030] In the bulb 1, an integral luminous body 4 is arranged axially. Such as Figure 1b It can be clearly seen from the magnifying glass that the luminous body is composed of a well-known double helix tungsten filament 4a-4c, and the ...

Abstract

The invention relates to a compact high-voltage electric light-bulb. As the illuminating body, said bulb comprises a triple coil in the form of a double helix (4), which in turn is configured from a double spiral (4a-4c). The invention allows high-voltage electric light-bulbs with compact dimensions and high light intensities to be produced.

Description

Technical field [0001] The invention relates to a small high-voltage electric incandescent lamp. [0002] The concept of high-voltage incandescent lamp generally refers to all incandescent lamps that can be directly connected to a power supply voltage such as 115 volts or 230 volts without connecting a voltage transformer such as a transformer or an electronic converter. [0003] Among them are small high-voltage halogen incandescent lamps, for example for a 230 volt supply voltage. Halogen incandescent lamps are generally filled with inert gases such as nitrogen, xenon, argon and / or krypton. The bulbs contain halogen additives that maintain a tungsten-halogen cycle to prevent the bulb from turning black. [0004] This type of lamp is suitable for both general lighting and special lighting, combined with a reflector, for example for projection technology. [0005] Like the low-voltage halogen lamp, the high-voltage halogen lamp is also constantly developing in the direction of sma...
