Panasonic and Panasonic Idemitsu OLED lighting announced that they ship lighting panels to local and overseas lighting module and lighting fixture manufacturers.
The product is a light source with a panel section as thin as approximately 2mm featuring the world’s highest level color rendering (no less than Ra90) and the world’s highest level luminance (3,000 cd/m2) as well as 30lm/W luminous efficiency, 10,000 hour durability (with 70% lumen maintenance factor) and 3,000K color temperature (light bulb color).
Panasonic introduce also the world’s most efficient white OLED at 128 lm/Watt.
Using a semi-spherical highly-refractive lens to enhance light extraction, and an OLED device measuring just 2mm x 2mm a luminous efficiency of 128lm/W was achieved
An OLED device made using those techniques and phosphorescent materials for red- and green-light emissions and a fluorescent material for blue-light emission has an area of 25cm2, achieved a luminous efficiency of 56 lm/W (at a brightness of 1,000cd/m2), a colour rendering index (CRI) of 91 and an lifetime was calculated to be more than 150,000 hours.
Panasonic Electric Works made another OLED device using only phosphorescent materials for red-, green- and blue-light emissions. With the same light extraction layer mentioned above, it has a luminous efficiency of 80 lm/W, a CRI of 83 and a lifetime of only 10,000 hours.
