Frankfurt exhibition] OLED high-end lighting market has been opened

This exhibition is among the many manufacturers invariably display OLED lighting products. Especially when the general LED lighting product technology has been relatively mature, LED lighting prices are also cheap to weigh two, to buy garlic to the point of the onion. A new generation of OLED light seems to bring a new bright spot for this exhibition.

The display of OLED lighting products manufacturers a lot, but most of the OLED lighting panel is nothing more than from South Korea, Japan, Europe that several OLED panel factory. Therefore, this time we are on behalf of these several OLED lighting manufacturers to look at their technical progress.

LG Display

First in the LG Display (hereinafter referred to as LGD) booth, everywhere you can see the light soft, and even a variety of irregular shape of the OLED panel lights. From the appearance and brightness to observe, it seems that compared to previous years to see the exhibition of OLED lighting products more commercialized. From the outside, the flexible substrate and packaging materials produced by the flexible OLED panel lights, lighting manufacturers to develop the lighting is more flexible and flexible.

LG Display of the exhibition can be seen everywhere in the light and soft, even OLED panel lamps of various irregular shapes. (all images: LEDinside)

From the efficiency of observation, LGD OLED panel lamp luminous efficiency has reached 80-90lm/W. Although efficiency can not be compared with LED lighting. But for decorative lighting, or lighting products have been more than enough. The LGD for OLED lighting market positioning is also very clear, is the early high-end lighting applications market. So at this stage has been with a considerable number of designers to discuss cooperation in the development of OLED lighting products, such as well-known Ingo Maurer and other industrial designers.

Ingo Maure designed OLED table lamp, the appearance is very simple.

The cost of the problem, has been the most criticized OLED lighting pain points. Two years ago, a square meter (One square meter) price is still around $100. But according to the LG Display OLED lighting marketing department assistant director Joon Park (Joon Park, Vice President, Head of OLED Lighting Sales & Marketing Division) said that a breakthrough in the past two years of LGD technology, and can reach the stage of mass production. In particular, OLED lighting division, from LG Chem was re divided into LG Display, you can use OLED Display technology and capacity to expand the OLED lighting business. Although the current lighting OLED panels are still in the two generation line production, but the factory price has been able to come to $30 U.S. dollars. At the same time, LGD also announced in this exhibition will be a new generation of five generation line capacity to expand OLED lighting capacity, capacity is completed, will have a monthly production capacity of 15000 pieces of glass substrate. So there is a lot of room for future price decline.

LGD is currently able to produce the largest OLED panel size up to 330*330mm.

Sumitomo Chemical

Almost every time in the Frankfurt lighting show met Sumitomo chemical, this is no exception. The design of the booth, or as in the past with a variety of colors OLED panel lights, made of decorative purposes. Sumitomo chemical positioning in OLED lighting is also very clear, that is, the use of a variety of color OLED panel to make decorative lighting products. As for efficiency, the OLED luminous efficiency of the full-color series is about 5LM/W. Or can only be used for decorative purposes. But the white part of the current luminous efficiency is about 30-40LM/W, but prototype has been able to 60LM/W. Although the production technology of Sumitomo chemical is a printing technology, the theoretical cost should be very competitive, but still need to break through the material technology, so it has not reached the scale of production economy.

Sumitomo chemical "OLED JARDIN" is a symbol of the "sky garden", composed of the Polymer OLED panel, creating a wide range of accessible space and elegant Japanese style.

OLEDWorks

U.S. company OLEDWorks in the end of 2015 to complete the acquisition of Philips's OLED assets and patents, but also in this exhibition to showcase new OLED products. At present, the standard production of OLED panel lights mostly in 120*120mm, luminous efficiency of about 40~50LM/W. The new generation of Brite 2 OLED panel lamp CRI greater than 90, color temperature 3000K and 4000K to choose from. Maximum brightness up to 8300 CD / m2, light efficiency of about 57LM/W. At the present stage, there are two shapes: square and rectangle.

Brite 2 OLED panel lights are square and rectangular shapes for customers to choose two.

LEDinside for the development of OLED lighting also made some summary:

General lighting

General lighting, at this stage each manufacturer can produce a large number of OLED lighting products generally fall luminous efficiency 40LM/W. Only a few first-line manufacturers can reach 80~90LM/W. The cost of LED lighting is very different, although the OLED price compared to two years ago, many have fallen. However, most manufacturers offer a square meter price mostly fall between $60~70. Only LGD dare to declare the price reached $20~30 level.

From the lighting development perspective, the past due to bottleneck luminous efficiency and area lighting, OLED most can only design a decorative light, table lamp, floor lamp or. But now, whether it is the area or luminous efficiency has been a breakthrough, you can see the design of commercial lighting, or other lighting type. Even thinner, and properties can be bent, can also be combined with furniture, can even embed in different building materials as a light source.
