LUMA Application AREAS
Advanced Luma Fine Wire Solutions
for the Lighting Industry
Historical Expertise and Modern Applications
For over nine decades, Luma has been a trusted supplier of high-quality tungsten and molybdenum wires tailored to meet the needs of the lighting industry. Originating from the Luma Lampan company, founded in 1930 as a pioneer in light bulb manufacturing, Luma has cultivated a legacy of precision and innovation in wire production. While advances in lighting technology have reduced the reliance on tungsten and molybdenum wires, these materials continue to play a pivotal role in niche applications requiring exceptional performance.
Applications of Tungsten and Molybdenum Fine Wires in the Lighting Industry
Medical Specialty Lighting
Tungsten and molybdenum wires remain critical components in the manufacture of medical-grade specialty lighting. These wires are essential for producing high-performance lamps used in hospitals, surgical suites, and dental clinics, where precise illumination is vital for patient care and procedural accuracy. Their ability to maintain structural integrity at high temperatures ensures consistent light output in demanding environments.
Microlamps
The production of microlamps demands wires with ultra-fine diameters, a specialty of Luma’s manufacturing processes. Tungsten and molybdenum wires are integral to these compact light sources, which are widely used in precision instruments and devices where size constraints necessitate miniaturized components without compromising functionality.
Halogen Lamps and
High-Intensity Discharge (HID) Lamps
Tungsten wires are a fundamental component in halogen lamps, known for their bright, energy-efficient light. Similarly, HID lamps rely on the robust properties of tungsten and molybdenum wires to deliver high-intensity illumination for applications such as automotive lighting, stadium floodlights, stage lighting, and industrial settings. These wires contribute to the lamps’ durability and efficiency by withstanding VERY high operational temperatures and sustaining consistent electrical performance.
Tungsten as the filament material in a.o. Halogen lamps is chosen for several reasons:
- High Melting Point: Tungsten has one of the highest melting points (around 3422°C or 6192°F), making it ideal for withstanding the high temperatures generated in halogen lamps.
- Durability: Tungsten is durable and can endure the constant heating and cooling cycles typical of halogen lamps.
- Efficient Light Emission: Tungsten emits visible light efficiently when heated, making it suitable for halogen and incandescent lamps.
- Halogen Cycle Compatibility: The halogen cycle helps prolong the life of the tungsten filament. Halogen gas inside the lamp reacts with tungsten atoms that evaporate from the filament, redepositing them back onto the filament rather than allowing them to collect on the glass.
Ultra Fine Wires - a part of the future Lighting Industry
The Role of Non-Sag Tungsten in High-Performance Wire Production
A distinguishing feature of Luma’s fine wire production is the use of non-sag tungsten as the primary feedstock material. Non-sag tungsten, alloyed with potassium, is engineered to resist deformation under high thermal and mechanical stress. This property makes it uniquely suited for applications where dimensional stability and prolonged performance are critical.
Additionally, Luma’s capability to manufacture wires with extremely fine diameters down to 4 microns (0,004 mm) enhances their utility in modern lighting applications. The combination of advanced material properties and precision manufacturing ensures that Luma remains a preferred supplier for high-performance lighting solutions.
Commitment to Innovation in the Lighting Industry
Although technological advancements have diversified the materials used in contemporary lighting systems, Luma continues to support the industry with specialized tungsten and molybdenum wires. The company’s long-standing expertise and ability to adapt to evolving demands reinforce its commitment to delivering high-quality materials for both traditional and innovative lighting applications.
Luma’s enduring contributions to the lighting industry underscore its dedication to meeting the challenges of modern illumination technologies while honoring its historical roots in light-bulb manufacturing.
