OSRAM with four core technologies, to build a full range of lighting products line LED

Remember the end of last year, OSRAM announced to the general lighting market as the strategic goal of the long-term development of a company, will build a six inch substrate in Malaysia to invest 1 billion euros LED chip factory, shook the entire LED industry. The OSRAM Opto Semiconductors in order to declare the determination of the development of LED lighting, the recent launch of a series of solid state lighting innovative product technology seminar in the Asia Pacific region.

OSRAM opto create a full range of LED lighting product line, positive from the lighting market

The meeting of the central division of the Department of long photoelectric semiconductor display for different lighting products developed by the full range of LED products. OSRAM Opto Semiconductor solid-state lighting market director Michael Schmitt said in a interview with LEDinside interview since last year, OSRAM Opto Semiconductors conforms to the trend of the market, the development of more than and 100 LED device items, and for LED lighting applications market to do different segments, including small and medium power with a high cost of LED, high power LED, new the development of CAS (Chip Array SMD), even taking the flagship high-end COBLED lighting applications such as a full range of product lines. In order to get rid of the fierce competition in the market price, OSRAM Opto Semiconductors with master technology, the LED key from the substrate, chip, package, phosphor and other patented technology to create the perfect light source quality.

Innovative phosphor conversion technology, so that the performance of LED light source to exceed the performance of ceramic gold halogen lamp

Especially in the high-end commercial lighting space, the client for the increasingly high quality requirements of light. Therefore, OSRAM Opto Semiconductors in the COBLED SoleriqS13/S19 series of products, the introduction of the Halide (Brilliant Color) technology, making the LED light source can be comparable to the ceramic metal halide lamp (Ceramic Metal). The technology through innovative phosphor conversion technology to enhance color saturation (color gamut), and combined with CRI and FCI (Feeling of Contrast Index) and other indicators to the perfect interpretation of color.

In addition, how to achieve uniformity of color difference between the needle LED lighting, commercial lighting is an important topic in the field, especially in the high-end commercial lighting space, or art gallery and other application field will require very uniformity of color. But even LED manufacturers to do the 3 step macadam, but between different LED lamps will still have the problem of color deviation. Therefore, many manufacturers are acquiring the hope to build 2, or even LED light source products under 1 step macadam ellipse. Through the higher color tolerance standards (Higher SDCM standard), more stringent bin to create a high quality lighting source. But relatively speaking, the cost has increased a lot. But the problem is really solved?

OSRAM Opto Semiconductors is proposed 10 degrees Binning concept. In particular, this 10 degree Binning technology in 2016 after the Frankfurt Lighting Exhibition (L+B2016) on display, get a good response LED lighting customers. And OSRAM's solid state lighting market director Michael Schmitt also explained what we mean 10 degrees Binning concept.

What is 10 Binning?

At this stage, most of the LED vendors and lighting manufacturers are still dependent on the traditional CIE19312 XY color coordinate system. However, due to the different wavelengths of blue chips with fluorescent powder composed of white LED, although the same color coordinates, but the visual will see some differences.

The simple concept of 2 degrees is 0.5 meters distance to the human eye in the observation of the color disc 20mm scene, and the state of Jordan 10 degree view of the eye in the 0.5 meters distance see 90mm color wheel. There is still some color gap between the two exist. The difference between the two lies in 10 degrees Binning technology closer to the visual experience of real life.

In the LED bin adjustment, XY is to coordinate the macadam (Scale), adjusted to U''''V''''coordinates (Scale). From the color coordinate diagram (color space), from the oval into a round so that color looks more uniform.

And this technology is particularly suitable for use in a single light source lighting products. For example, the use of COB to create a projection lamp, track lights and other products. In addition, we are most concerned about the creation of 10 degrees Binning LED products will increase the cost of. Michael Schmitt think it will not, because it is only a way to change the way bin Bin, but also follow the technical report of CIE2015, any LED vendors can use this color in a different way. Therefore, the new 10 Binning for customers is completely painless conversion, there will be no effect.
