In printers and copiers, the fusing unit is one of the key components ensuring the quality of output documents. As the core component of the fusing unit, printer high-efficiency halogen lamps, with their unique thermal radiation and halogen cycle technology, bring high efficiency and stable performance to the printer.
I. Core Technology Principles
Thermal Radiation and Halogen Cycle
Halogen lamps emit light by heating a tungsten filament at high temperatures, which combines with halogen gases such as iodine and bromine to achieve a "regeneration cycle." This process not only improves luminous efficiency but also significantly extends the filament life to 2000-4000 hours. This mechanism gives halogen lamps high durability and stability. Their spectrum includes visible light and infrared radiation, making them suitable for both lighting and heating applications. Especially during the printer's fusing process, the infrared radiation emitted by the halogen lamp can quickly and evenly heat the toner, melting it and firmly adhering it to the paper, thus ensuring high-quality printing results.
Fusing and Exposure Applications
In printers, halogen lamps are primarily used in the fusing unit. After toner is transferred to paper, it needs to be heated to melt and bond firmly to the paper surface. Halogen lamps use infrared radiation to rapidly heat the toner to a molten state, achieving permanent fixation on the paper. In electrostatic copiers, halogen lamps serve as the exposure light source, working in conjunction with selenium-tellurium alloy photosensitive elements to ensure accurate reproduction of the original colors. This precise color matching is crucial for ensuring the quality of copied documents.
II. Key Technical Parameters and Performance Indicators
Power and Size
The halogen lamps used in printers have a wide power range, from 80W to 16kW, meeting the needs of different printing scales. The luminous length covers 150mm to 1800mm, allowing selection of appropriate specifications based on the actual application scenario. The operating voltage is typically 220V±10% or 380V, ensuring stable operation in various industrial environments. Stable current contributes to improved overall system reliability.
Energy Efficiency and Lifespan
Although halogen lamps have a luminous efficacy of approximately 15-20 lumens/watt, lower than LED lamps, their lower manufacturing cost still provides a significant cost advantage in many applications. Typical lifespans range from 1000 to 5000 hours, with some industrial models reaching 8000 hours, supporting 24-hour continuous production. This is particularly important for commercial printing environments requiring long-term stable operation.
Spectral Characteristics
Halogen lamps produce a spectrum close to natural sunlight, which is especially important for applications requiring precise color matching. Furthermore, their high proportion of infrared radiation makes them ideal for fixing processes requiring rapid heating. This characteristic allows halogen lamps to provide sufficient heat in a short time, thereby accelerating printing speed and improving work efficiency.
III. Safety Procedures and Key Operating Points
Installation and Maintenance
To ensure optimal performance and safety of halogen lamps, proper installation and maintenance are crucial. First, avoid touching the lamp tube directly with your hands during installation. It is recommended to wear gloves or use a lint-free cloth for handling to prevent oil stains from affecting light uniformity. Secondly, during installation, pay attention to the direction of the exhaust port, ensuring it faces upwards to allow unobstructed gas circulation within the halogen lamp tube. During transportation, appropriate securing measures must be taken, and shockproof treatment should be implemented to prevent filament breakage and damage.
Heat Dissipation and Protection
Considering the significant heat generated by halogen lamps during operation, a good heat dissipation design is essential. This machine is equipped with a forced-air cooling fan, effectively controlling the temperature to ≤50℃ to prevent overheating and related safety hazards. Furthermore, the reflector design requires special precision to reduce infrared heat radiation to the glass cover; some models also feature infrared filters for further enhanced safety.
In conclusion, printer high-efficiency halogen lamps, with their advanced thermal radiation technology and halogen circulation mechanism, provide powerful support for modern printing equipment. Whether from a technical principle, performance indicator, or safe operation perspective, it is an indispensable component for ensuring print quality and efficiency.
