Panasonic Electric's joint venture company launches OLED lighting with a color rendering index of up to 90

Matsushita Electric Industrial Co., Ltd. and Izumi Electric Co., Ltd., a joint venture company of Matsushita Electric Co., Ltd. (hereinafter referred to as PIOL), supply organic EL lighting panels for the Japanese and foreign markets. The panel's average color rendering index (Ra) is over 90, which is the "world's highest level" in mass-produced organic EL lighting panels. Matsushita Electric is scheduled to launch an organic EL lighting module that combines control circuits on an organic EL lighting panel from December 2011.



The organic EL lighting panel that PIOL has already started to offer is 97mm x 90mm and has a thickness of only 2.11mm. The area of ​​the light-emitting portion is 80 mm × 80 mm. The weight is 38g. The luminous efficiency of the bulb color of 3000 cd/m 2 and the color temperature of 3000 K is 30 lm/W, and the service life is 10,000 hours (the luminous flux is reduced to 70% of the initial time).


The organic EL lighting module that Panasonic Electric Works is scheduled to go on is scheduled to have a size of 102mm × 95mm × 8.9mm. The thickness after embedding the control circuit is also controlled at 9 mm. The weight is 100g. The module state efficiency is 21 lm/W. It has a dimming function that is adjustable from 10% to 100%. It is easy to embed in a thin lighting fixture that is integrated with buildings and equipment.


Although the luminous efficiency of organic EL lighting panels is higher than that of incandescent bulbs (about 15 lm/W), it is still slightly inferior to fluorescent lamps and LED lighting. However, the luminous efficiency of the organic EL illumination panel will continue to increase in the future, and it is expected to exceed the fluorescent lamp in the future. According to the development plan of the panel, the luminous efficiency will increase from the current 30 lm/W to 100 lm/W in 2015 and 130 lm/W in 2018. Not only is the luminous efficiency, it is said that it will also increase the brightness, extend the life, and enlarge the area of ​​the panel.
