Problems solved by technology

[0002] The cold resistance of the existing incandescent lighting filament is only one-tenth of the thermal resistance. Therefore, a large inrush current will be generated at the moment of turning on the light, which will not only easily cause damage to the lighting filament, but also reduce the service life of the incandescent lamp. It also causes waste of energy

Embodiment Construction

[0015] Such as figure 1 As shown, the preheating lighting lamp of the present invention includes two conductive brackets 1, conductive brackets 6, and lighting filaments 2 fixed on a glass bracket 7. One end of the lighting filament 2 is connected in series with the conductive bracket 1, and the other end of the lighting filament 2 Connected to the conductive rod 3, the conductive rod 3 is respectively connected to one end of the preheating filament 4 and the bimetal switch 5, the other ends of the preheating filament 4 and the bimetal switch 5 are respectively connected to the conductive support 6, the lighting filament 2 and the preheating filament 4 is located on both sides of the bimetal switch 5, and the three are arranged parallel to each other. The distance between the preheating filament 4 and the bimetal switch 5 is 10mm, and it can also be 3~30mm, but if the distance is far, the connection The time required to turn on the bimetal switch 5 will also be relatively long. T...

Abstract

The warm-up lamp comprises the two electric conductive brackets fixed in the glass brackets and the illuminating lamp filament. The one end of the illuminating lamp filament is cascaded to the one of the electric conductive brackets, the other is connected to the conducting pole which also is connected to one end of the warm-up filament and the bimetal switch. Another end of warm-up filament and the bimetal switch is connected to the conductive bracket respectively. The conducting pole is fixed in the glass bracket. In the moment of switching on, the large surge current will not be generated since the warm-up filament with large resistance is cascaded in the circuit. Thus, the surge current is avoided so as to prolong the service life of the lamp.

Description

Technical field [0001] The invention relates to a lamp, in particular to a preheating lighting lamp. Background technique [0002] The cold resistance of the existing incandescent lamp lighting filament is only one-tenth of the thermal resistance. Therefore, at the moment of turning on the lamp, a large inrush current will be generated, which not only easily causes damage to the lighting filament, but also reduces the service life of the incandescent lamp. It will also cause a waste of electrical energy. Summary of the invention [0003] The purpose of the present invention is to provide a preheated illuminating lamp with a long service life. [0004] The preheating lighting lamp of the present invention includes two conductive brackets fixed on the glass bracket and a lighting filament, one end of the lighting filament is connected in series with one of the conductive brackets, the other end of the lighting filament is connected with a conductive rod, and the conductive rods ar...
