White LEDs are currently widely used in lighting and backlighting applications, and have been recognized globally as a key lighting technology. As the application fields of LEDs continue to expand, the demand for higher performance and reliability is also increasing.
Traditional white LEDs typically use a method where phosphor is mixed with silicone resin. Blue light from the LED chip excites the phosphor, which then emits green, yellow, and red light, combining to produce white light. However, due to the poor weather resistance and thermal stability of the organic resin, issues such as light degradation, color shift, yellowing, and material aging often occur. These problems limit the use of traditional LED packaging in high-end lighting applications.
To address these limitations, Yantai Hilde New Materials Co., Ltd. (referred to as "Hilde") has developed an innovative solution by combining glass with excellent optical transmission, thermal stability, and weather resistance. Their glass ceramic fluorescent sheet technology overcomes the shortcomings of conventional LED packages, such as low optical density, poor thermal stability, and yellowing.
In conventional LED and LDP technologies, phosphors are usually dispersed in organic resins for encapsulation. However, prolonged operation can lead to heat-induced damage, causing cracking, yellowing, and degradation of the resin. This results in reduced luminous efficiency and color coordinate drift.
Glass ceramic fluorescent sheets offer significant advantages: uniform color, concentrated color distribution, high temperature resistance, excellent thermal stability, minimal color shift, and strong resistance to yellowing.
Especially in high-power applications, the thermal conductivity of conventional silicone resin packaging is less than 0.2 W/m·K, while Hilde's products can achieve over 1000 lm/mm².
According to reports, Hilde completed its R&D work on this technology in July of this year. Within just four months of mass production, their glass ceramic fluorescent package products have received widespread recognition from customers for their superior performance.
Shenzhen Ajibi Optoelectronics Technology Co., Ltd. said: “The illuminating film provided by your company performs very well at high optical density! I hope to sign the supply contract as soon as possible.â€
Leijie Technology Co., Ltd. stated: “The optical properties of the fluorescent films are excellent and the price is reasonable. Our company will gradually replace imported products.â€
Guangzhou Jinglifeng Optoelectronics Technology Co., Ltd. commented: “The performance after packaging and testing is better than that of traditional rubber powder mixed packaging. We hope to further cooperate.â€
Guangyao Optoelectronic Energy Saving Technology Co., Ltd. shared: “I’ve been searching for a suitable fluorescent film for over a year, and finally found a good partner.â€
Ningbo Shengpu Optoelectronics Co., Ltd. noted: “The optical properties of the fluorescent films are comparable to those of Taiwanese samples.â€
Delta Electronics Industry Co., Ltd. said: “The product’s optical performance is excellent, and the price is reasonable.â€
Shenzhen Yangyang Electronic Technology Co., Ltd. added: “The color point distribution is concentrated, it has high temperature resistance and thermal stability, and the color shift is minimal. It's a great product. We hope to further cooperate!â€
Based on the innovation of the "Glass Ceramic Fluorescent Sheet" technology and its strong market competitiveness, Hilde decided to submit this technology for the 2017 Advanced Technology LED Golden Globe Award in the category of "Innovative Technology of the Year."
