The first mass production in China|Removal of the core affliction, Hongli Optoelectronics, Smectic pushes the anti-vulcanization "screen seal" series LED

Screen seal - barrier blockade, shielding all harmful substances from LED packaging products.

Hongli Zhihui announced the launch of anti-vulcanization "screen seal" series LED products, using advanced and unique PPL technology to completely solve the blackening problem caused by vulcanization, oxidation and bromination of LED devices, with higher reliability and reliability. And long life. Hongli Zhihui has been striving to improve the anti-vulcanization performance of LED devices and has rapidly achieved mass production. Recently, the AT35 (upgraded version of PCT2835) of this series of products has successfully achieved mass production, which is the first in China.

AT35--PCT bracket + PPL technology

The AT35 is the first of its kind to be mass-produced and the most demanding product on the market (PCT2835, the main indoor lighting). From research and development to mass production, Hongli Zhihui's R&D team deeply analyzes the truth of LED brightness attenuation, and verifies the best LED anti-vulcanization solution according to the principle of anti-vulcanization, eliminating the core defects of LED products.

1 AT35 reliability - vulcanization experiment

2 AT35 reliability - high temperature and high humidity aging

3AT35 reliability - bulb lamp aging (pin temperature 110 °C, 1000 hours)

4AT35 reliability - thermal shock (minus 40 ° C - 105 ° C)

According to the relevant person in charge of Hongli Zhihui: The realization of the anti-vulcanization technology mainly uses a unique PPL technology to deposit a layer of inorganic substances on the surface of the silver plating layer. The inorganic substance has excellent compactness and effectively blocks sulfur and oxygen. The reaction of bromine and other substances with the silver plating layer; and has long-lasting and stable chemical properties, and has outstanding performance in corrosion resistance and high temperature resistance, completely solving the blackening problem caused by vulcanization, oxidation and bromination. Currently, the PPL technology has successfully applied for three invention patents.

AT30/AT50/AT70--EMC bracket + PPL technology

The Smect team of Hongli Zhihui is the leader in domestic EMC technology. The company's anti-vulcanization PPL technology is also perfectly applied to EMC series products (AT30/AT50/AT70 are upgraded versions of EMC3030/ 5050/ 7070 respectively) The combination of strong and strong gold will definitely become a dark horse in the LED packaging industry. "EMC bracket + PPL technology will re-energize the long life of LED lamp beads. The LED lamp beads of this packaging process can achieve life (L70) for more than 50,000 hours in most applications, in more demanding applications. Brilliant. "The relevant technical leaders showed great confidence in the company's EMC anti-vulcanization products.

For example, for outdoor lighting applications (such as street lights, floodlights, landscape lighting, etc.), especially EMC5050 products, light efficiency 220LM/W can be achieved in 1W; in addition to high temperature resistance, yellowing resistance, excellent UV resistance In addition to performance advantages, EMC's LED lamp beads combined with PPL technology will achieve higher reliability and longer life. It is believed that with the maturity of LED anti-vulcanization technology, Hongli Zhihui's EMC5050/7070 products will achieve a rapid growth in outdoor applications.

"Screen seal" series product family

Hongli Zhihui's “screen seal” series of LED products cover a full range of SMD LED products from PPA + PPL, PCT + PPL, EMC + PPL, etc. Customers can choose matching anti-vulcanization products according to application requirements. In addition to the AT35, the company's mass-produced product models can also mass produce AT30/AT50/AT70.

Whether it is indoor lighting, outdoor lighting, or even more demanding automotive lighting, Hongli Zhihui anti-vulcanization "screen seal" series of LED products can bring you higher product performance and provide more different The possibility of lighting applications. In the future, Hongli Zhihui will continue to enhance the technical performance and cost performance of this series of products, expand the anti-vulcanization LED product series, and provide the best LED light source selection and anti-vulcanization solution for different application needs of the industry.

The company's "screen seal" series of LED products are now accepting sample applications, relying on Nanchang LED production base can provide standard delivery date. Interested customers can contact the company's direct sales outlets to request sample trials, thank you.
