The 11th International Lighting Comprehensive Exhibition "LighTIng Fair 2013" was held at Tokyo Ariake International Convention and Exhibition Center on March 5-8, 2013. This article will introduce a variety of organic EL lighting exhibited in this lighting exhibition in the form of photos.
Organic EL, also known as OLED, is translated into organic light-emitting diode in Chinese. A TV that uses this material to make a display panel is an organic EL TV. Compared with the current commonly used LCD TVs and plasma TVs, organic EL TVs have many advantages such as lightness, thinness, power saving, good picture quality, high resolution, fast response, and flexibility. Simply put, the shortcomings of flat panel TVs on the market will be overcome. At the lighting exhibition in 2013, there were many creative lightings focusing on these characteristics.
Toshiba exhibits transmissive organic EL panel and wireless power supply organic EL lighting
Toshiba and Toshiba Lighting Technology exhibited the transmission type organic EL lighting panel and the organic EL with wireless power supply function at the lighting technology exhibition "LighTIng Fair 2013" (5-8 March 2013, Tokyo Ariake International Exhibition Center) Lighting board. It was introduced together with the use of new lighting fixtures in the short play.

Can achieve "window lighting" that does not illuminate the outside
Transmissive organic EL lighting panels generally use transparent electrodes on both the positive and negative electrodes, so they appear transparent when turned off. It is not uncommon for an organic EL panel to remain transparent only when the light is turned off, but Toshiba ’s transmissive organic EL lighting panel uses an independent element structure different from the ordinary transmissive organic EL lighting panel to concentrate the emitted light in one direction, unlike other The transmissive organic EL panel is completely different. Toshiba ’s technicians said, “About half of the existing transmissive organic EL lighting panels emit light toward the front through the back, while only about a few tenths of the light from the lighting panel developed this time comes from the back. leakage".

If a large amount of light leaks to the back of the lighting panel, when using transmissive organic EL lighting on the window, not only the indoor but also the outdoor will be illuminated, which may result in wasted power and light pollution. The transmissive organic EL panel this time can suppress the light leaking to the outside, so it can easily realize a new lighting appliance that is a transparent window during the day and a wall lamp at night.
In fact, this lighting board uses the same technology as the transmission type organic EL lighting board introduced by Toshiba Lighting Technology and FamilyMart at "FamilyMart Funabashi Jinshan Store" (Funabashi City, Chiba Prefecture) on February 8, 2013. .
Using the wireless power supply function, the appearance design is decided by the user himself
Another organic EL lighting exhibited by Toshiba can be powered by electromagnetic induction wireless power supply technology, and users can change the configuration of the light-emitting board at will.
NEC Lighting has also developed organic EL lighting fixtures that can be changed by users, but in order to achieve power supply, electrodes are installed on the panel. This time, Toshiba's design eliminates the need for electrodes, which makes it easier to change the panel configuration.
