The researchers used high reward model LED Wacker silicone

Wacker chemical Limited by Share Ltd yesterday awarded the "Philipp M ller Alexander, Wacker Innovation Award" award he developed a new type of optical silicone series. To launch the LUMISIL Wacker brand? New silicone elastomers, using the first time they will be without casting and molding process can be through a complex process into optical lens need directly on the light-emitting diode chip. The forming and assembling of the light-emitting diode optical element is carried out at the same time with high efficiency. So it is a major breakthrough in the production of light-emitting diodes at low cost. The prize for the euro 10000 innovation award this year in the field of product innovation.

The light emitting diode has a great potential in energy efficiency, so the growth of this market is very optimistic about the prospects, "Dr. Sittenthaler WilhELm, director of the Wacker group in the word said. "We predict an annual growth rate of about 20% in this area. This means that, even from an economic point of view, this innovation is also likely to become one of wacker's great success. "

Light emitting diodes (LEDs) are considered to be the future of lighting because they consume only a small portion of the traditional incandescent or energy-saving lamps when they are exposed to high lighting power. The efficiency of advanced LED is ten times that of incandescent lamps. However, in order to achieve the output coupling and distribution of diode light, high efficiency light-emitting diodes need an optical lens. In the past few years,

The efficiency of the light-emitting diode is greatly improved, which makes the organic materials used so far can not continue to withstand the intensity of luminous flux. For this reason, the production of advanced high efficiency light-emitting diodes in the future will be the main use of silicone as a packaging and optical materials, because of the requirements of organic silicon heat-resistant and light stability. The disadvantage is that the geometry of the lens has so far been achieved using complex die casting and molding processes.

Now, the use of LUMISIL series of silicone elastomers for the first time realized the use of distribution (Dispens) process in a process directly on the light-emitting diode chip on the production of bare lens. The perfect lens geometry can be obtained by using a new UV controlled hardening mechanism. LUMISIL? 419 UV has excellent adhesive properties, it can even use silicone encapsulation ellipsis used so far, because it has the optical function, but also play a protective role of the light emitting diode chip. In this way, the light emitting diode component with the silicone lens can now be produced in large quantities with relatively few equipment and process costs. One of the world's leading light-emitting diode manufacturers have used LUMISIL, its excellent transparency, excellent mechanical strength and long-term stability under extreme ultraviolet radiation has been confirmed.

Alexander Wacker Innovation Award

Since 2005, the Munich based chemical group has been awarded an annual research conference to reward employees who have made outstanding achievements in research and development. According to the company's founder named the bonus of 10000 euros, Alexander Wacker innovation award every year in the field of product innovation, process innovation and basic research in the field of the issue of the award of. Next year, this full range of competition will be held in the field of technology innovation.
