Technical Field
The invention relates to the technical field of halogen lamps, in particular to a halogen lamp with a mechanical dimming structure.
Background
Halogen lamps are a common type of lighting device, typically consisting of a plurality of halogen elements (e.g. tungsten filaments) for generating light. Halogen lamps are commonly used for illumination of workplaces, such as factories, offices, construction sites, etc. The halogen lamp works by heating tungsten filament to make it emit light. When heated to high temperatures, the tungsten filament emits ultraviolet and visible light. These lights can illuminate the surrounding environment, enabling us to see objects clearly. The halogen lamp can produce a high brightness and can provide sufficient illumination. The halogen lamp has a long life and can last for months or even years.
However, the existing halogen lamp has certain drawbacks: the brightness adjustability of halogen lamps is not as easy to control as other types of lighting devices such as incandescent and fluorescent lamps. Halogen lamps typically use different tungsten filaments to produce different light intensities, and different types of tungsten filaments also emit light of different intensities and color temperatures. Therefore, it is necessary to control the brightness of the halogen lamp using a dimmer to achieve a desired illumination intensity and color temperature. Dimmers are an electrical device that changes the luminous flux of a light source in a lighting device, adjusts the illuminance level, and are known as dimmers for large capacity and constitute a system. The basic principle of the dimmer is to change the current of the bulb by changing the voltage or current, thereby changing the brightness of the bulb. Dimmers are typically composed of three parts: dimming module, drive circuit and control circuit.
The conventional halogen lamp dimming device with the application number of CN201521131604.6 is characterized in that normally open contacts of contactors corresponding to brightness gears of the device are respectively connected between the output end of a transformer and a halogen lamp to realize output of different voltages, and coils of the contactors corresponding to the brightness gears are respectively and correspondingly connected between dimming connection terminals and zero lines of a power supply to realize conduction of the normally open contacts of the contactors.
