Halogenkretsar

Halogenkretsar, often referred to as halogen circuits, are electrical circuits designed to power and control halogen lamps. Halogen lamps are a type of incandescent lamp that utilizes a tungsten filament encased in a quartz envelope filled with a halogen gas, such as iodine or bromine. This halogen gas helps to regenerate the tungsten filament through a chemical cycle, extending the lamp's lifespan and maintaining brightness compared to standard incandescent bulbs.

These circuits typically involve a power source, which can be AC or DC depending on the lamp type, and may include components like transformers, ballasts, or simple resistive elements. For low-voltage halogen lamps, a step-down transformer is commonly used to reduce the mains voltage to a suitable operating level, usually 12V or 24V. Higher voltage halogen lamps, operating directly from mains voltage, may require more basic wiring.

Control elements within halogen circuits can range from simple on/off switches to more complex dimmers. Dimming halogen lamps can be achieved using resistive dimmers, leading-edge or trailing-edge electronic dimmers, or pulse-width modulation (PWM) control, although some methods are more efficient and suitable than others. The specific design of a halogen circuit is crucial for ensuring the lamp operates at its intended voltage and current, thereby optimizing its performance and longevity. Safety considerations, such as proper insulation and heat dissipation, are also integral to the design and installation of these circuits.
