As healthy eating concepts take root worldwide, air fryers have become a standard appliance in global home kitchens. According to an industry report by Fortune Business Insights, the global air fryer market reached USD 9.4 billion in 2025 and is projected to grow to USD 10.54 billion in 2026, with a compound annual growth rate of 8.99%. The Asia-Pacific region dominates with a 46.34% market share. In the Chinese market, data from AVC shows that the full-channel retail sales of air fryers reached RMB 16.5 billion in 2025, up 16.2% year-on-year, while the penetration rate of smart products has risen to 41%. In this high-growth track, the heating lamp — as the "heart" of the air fryer — directly determines cooking efficiency and food quality.

Infrared Heating Technology Emerges as the Core Direction for Air Fryer Upgrades

Unlike traditional hot-air circulation, which relies on air as the heat transfer medium, infrared radiation acts directly on food molecules. An academic review published in the U.S. National Library of Medicine (PMC) points out that water molecules exhibit strong absorption of infrared energy at wavelengths of 3μm, 6μm, 12μm, and 15μm. Infrared heating can excite resonance of water molecules inside food, achieving uniform heating "from the inside out." Industry research data shows that the electrothermal conversion rate of infrared heating modules can exceed 92%, significantly higher than the 65%–75% conversion efficiency of traditional PTC hot-air systems. International brands have already taken the lead: France's Moulinex launched its Infra Heat infrared air fryer, which, according to the brand, delivers a 4-fold increase in cooking speed, while T-fal's InfraHeat series achieved a doubling of heating element warm-up speed in internal tests.

Three Major Series of Infrared Heating Lamp Solutions from Linyi Lanjing Optoelectronic

As an enterprise with nearly 50 years of deep involvement in the quartz heating field, Linyi Lanjing Optoelectronic Technology Co., Ltd. has launched three major series of infrared heating lamp solutions tailored for air fryer applications.

Halogen quartz heating lamps reach full power output within 1–3 seconds of being energized, radiating 0.76–2.5μm short-wave infrared with strong penetration that rapidly caramelizes and crisps food surfaces. With single-lamp power ranging from 800W to 2000W, they are currently the preferred solution for mainstream air fryers.

Carbon fiber heating lamps utilize pure black-body carbon fiber heating elements, with an electrothermal conversion efficiency as high as 95%–98%. They output 1.5–8μm medium-far infrared, delivering more uniform heating where food cooks evenly inside and out. With a service life of 8,000–10,000 hours and 10%–15% more energy-efficient than halogen lamps, they are ideal for high-end, large-capacity models.

Ruby heating lamps incorporate coloring ions such as chromium oxide into the quartz glass, filtering out over 90% of visible light glare and emitting a soft rose-red glow. Combining visual aesthetics with the advantages of medium-near infrared penetrating heating, they are well-suited for high-end, visually appealing products with viewing windows.

Full Industry Chain Strength and Global Recognition

Founded in 1976, Lanjing Optoelectronic started with quartz ore processing and has built a full industry chain layout from high-purity quartz sand to finished heating lamps. The company holds 30 authorized patents, including 14 invention patents, employs 33 professional R&D personnel, and has established industry-university-research collaborations with institutions such as Chengdu University of Technology and Linyi University. Its products have passed multiple international certifications including GS, CE, RoHS, and UL, and the company provides OEM manufacturing for well-known brands such as Samsung, HP, Pantum, Lenovo, and Deli, with a sales network spanning over 100 countries and regions worldwide.

Against the backdrop of the continuously expanding air fryer market and the accelerating penetration of infrared heating technology, Lanjing Optoelectronic is empowering home appliance brands to achieve product upgrades through core component technology, driving healthy cooking toward greater efficiency, energy savings, and better taste.
