Hai cercato: Dispositivi luminosi alogeni
Halogen lamps have an internal chemical reaction that recycles evaporated tungsten back onto the filament, increasing their lifespan and maintaining the clarity of the bulb. Capable of operating at a higher temperature than standard gas-filled lamps of similar power, the lights produce a higher luminosity and colour temperature. The generally small size of halogen lamps permits their use in compact optical systems for projectors and illumination.
