Mitsubishi Chemical and Pioneer collaborate to develop OLED lighting components with a luminous efficacy of 52 lm/W

[High-tech LED News] In order to fully develop the OLED lighting business in 2014, Mitsubishi Chemical and Pioneer of Japan jointly developed the OLED components for lighting using the coating process from January 2010. Recently, a white light-emitting OLED device using a coating process to form a light-emitting layer has been successfully developed, and the luminous efficiency is as high as 52 lm/W, and the luminance half-life is as long as 20,000 hours at an initial luminance of 1000 cd/m 2 .

This element is formed by filming the lower layer of the element and the light-emitting layer by a coating process, and the upper layer is formed by vapor deposition.


Mitsubishi Chemical's OLED lighting source module "VELVE", which was scheduled to be launched in July 2011, uses a coating process only when the film is formed in the lower layer of the component. The luminous efficiency is 28 lm/W, which is scheduled to be mass-produced by the Northeast Pioneer.

This product is a currently popular flexible retractable multi-functional solar energy charger, the main functions are: solar energy charging storage system, mobile power, SOS signal and flashlight functions. It USES a high-performance lithium battery as a storage battery to charge the phone while receiving sunlight, and can use a strong flashlight at the same time. The product itself can be directly charged by the charging power adapter, or can be charged through the solar energy charging plate, which is very convenient to use. It is a good choice for your friends who love outdoor sports to solve the problem that the device does not have electricity at any time and place.
The FIZZ GLOBAL has developed one of the most compact solar energy rechargeables on the market. It is very portable, and its solar panels can be folded like an old-fashioned camera roll.
 FIZZ GLOBAL said it hoped the product would reduce carbon emissions during charging and that people would focus on clean energy.
