Progress and application analysis of PHILPS OLED lighting

PHILPS hopes to play OLED thin, can be processed into four angle, triangular and circular shapes, features a high degree of freedom, first attracted architectural design, industrial design and clothing design in the field of designer, without limitation of Yu Zhaoming use. PHILPS lighting Denneman said that the company's OLED lighting technology has been in a state of OK, and has received a small number of orders.

In fact, in Aachen, Germany, PHILPS science and technology plant has been installed by the organic material and metal material evaporation chamber series of production equipment for the production of OLED lighting appliances. The device is capable of producing OLED panels using a 400mm * 500mm glass substrate. Although not yet entered the stage of mass production, but from PHILPS's home page, has been able to buy a unit for OLED lighting appliances. The luminaire provided is divided into 30 types according to the shape, the luminous color (red, green, blue and white). The company is likely to launch a large number of OLED products in early 2010.

Luminous efficiency of 10 ~ 20lm/W also has the use

At this stage, PHILPS technology to produce OLED panel light-emitting efficiency is only 10 ~ 20lm/W, and incandescent equivalent, less than LED. Although the company development department manager OLED DietrichBertram said that "in the development of realization of 80lm/W", but in actual production, implementation and bulb type fluorescent lamp is the fastest 50lm/W estimation takes 3 years to achieve higher efficiency requires more than 5 years. Poor efficiency has become one of the reasons why OLED can not be applied to general lighting applications.

However, the application of OLED lighting decoration can not be said to be helpless. PHILPS Technology Development Manager OLED KristinKnappstein said, it can be said that it is because OLED lighting competitors can become the use of existing light, shapes of the OLED luminous body "by the designer's praise, OLED as a high value-added products, with new lighting purposes.

PHILPS technology believes that the next phase of OLED is as a general lighting. The company in the lighting exhibition, exhibited with the PHILPS design cooperation trial produced by the thin plate OLED panel arranged into the lighting equipment. Plate lighting can also be achieved by LED with light guide plate. But the use of LED, light guide plate will produce light loss, allegedly even if the luminous efficiency of 50 ~ 80lm/W, the actual efficiency will be reduced to 30 ~ 40lm/W. In contrast, the OLED lighting itself is luminous, the need for optical components is low, light loss is smaller. PHILPS technology Knappstein said: "because of the high efficiency of the system, so it can be called 'green'".

The idea of PHILPS lighting is to use the light source in accordance with the characteristics of the application of OLED in the need to diffuse light illumination, the application of LED in the spotlight. Because OLED lighting and LED can be used as digital switching control and dimming control, therefore, OLED also applies to the previously mentioned "intelligent lighting" system.
