Detailed Description

In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand and understand, the present invention is further explained by combining the following specific drawings.

As shown in fig. 1, the high-luminous-efficiency self-ballasted mercury lamp includes a lamp holder 1, an arc tube 2, a temperature switch 3, an iodine-tungsten lamp tube 4 and a ballast filament 5, wherein the arc voltage of the arc tube 2 is 90-110v, the rated voltage of the iodine-tungsten lamp tube 4 is 130v, the rated voltage for starting the ballast filament 5 is 70v, the arc tube 2, the iodine-tungsten lamp tube 4 and the ballast filament 5 are all connected in series and then electrically connected with the lamp holder 1, and the temperature switch 3 is connected in parallel with the ballast filament 5.

The temperature switch 3 is a bimetallic strip structure, the temperature switch 3 is a normally open switch, and the action temperature of the temperature switch 3 is 100-130 ℃.

The temperature switch 3 is a temperature switch 3 using a bimetallic strip as a temperature sensing element, when the electric appliance works normally, the bimetallic strip is in a free state, the contact is in a closed/open state, when the temperature rises to an action temperature value, the bimetallic element is heated to generate internal stress to act rapidly, the contact is opened/closed, and a circuit is cut off/connected, so that the thermal protection effect is achieved. When the temperature drops to the reset temperature, the contact is automatically closed/opened, and the normal working state is recovered.

When the electric arc tube 2 works, the high-temperature and high-pressure sodium vapor has extremely strong corrosivity, and common sodium-resistant glass and quartz glass can not be sufficient; the translucent polycrystalline alumina and the ceramic tube are adopted as the tube body of the arc tube 2, so that the arc tube has good high-temperature resistance, antibiotic sodium vapor corrosion resistance and good visible light penetration capability. In addition, the properties of the single crystal alumina ceramic tube such as high temperature resistance, sodium vapor corrosion resistance, light transmittance and the like are better than those of the polycrystalline alumina ceramic tube.

The ballast filament 5 is used as an auxiliary filament connected, when the self-ballasted mercury lamp is started, because the voltage of the arc tube 2 is very low, when the ballast filament 5 is started, because the voltage of the arc tube 2 is reduced, the ballast filament 5 must share 200v high voltage, therefore, the rated voltage must be set at 200v, after the self-ballasted mercury lamp is started, the voltage of the ballast filament 5 is reduced to 100-130v, the luminous efficiency of the ballast filament 5 is sharply reduced, and the light efficiency of the mercury lamp is reduced.
