Suppressing blackening of the valve wall in the "halogen cycle"! Preventing filament wear.
We will introduce the wavelength and lifespan of infrared halogen heaters. The peak wavelength can be calculated using 2897 divided by the color temperature (K), and by changing the color temperature of the halogen heater, it is possible to correspond to various wavelengths. The lifespan is affected not only by filament breakage but also by failures in the seal area. The "halogen cycle" helps to suppress blackening of the bulb wall and prevents filament wear. Compact and long-lasting, these are the characteristics of halogen lamps. 【Features】 ■ The peak wavelength is near-infrared (approximately 1.2μm) ■ The peak wavelength can be calculated using 2897 divided by the color temperature (K) ■ By changing the color temperature of the halogen heater, it can correspond to various wavelengths *For more details, please refer to the PDF document or feel free to contact us.

basic information
【About the Halogen Cycle】 ■ When current flows and the filament becomes high temperature, tungsten atoms evaporate from the filament. ■ They bond with halogen atoms from the enclosed halogen gas, forming tungsten halide. ■ The molecules float within the bulb and separate into halogen atoms and tungsten atoms near the high-temperature filament. ■ The tungsten atoms return to the filament, and the freed halogen atoms repeat the previous reaction. ■ This suppresses blackening of the bulb wall and prevents filament wear. *For more details, please refer to the PDF document or feel free to contact us.
