LED panel used for a window in a room
SWITCH currently sells into both the retail and commercial channels in North America.The company expects to expand its infrastructure-system businesses over the medium to long term, especially in view of increasing demand for energy infrastructure. The new facility will help to increase operational efficiency by consolidating engineer workforces engaged in design and development. It will also provide increased space for manufacturing and test-control equipment.LED lighting, now replacing incandescent, offers low power consumption and a long operating life. Toshiba is developing products that feature control of higher power LED, that support dimming and higher Led flood light and that deliver more accurate output current with higher efficiency.The samples are currently available and the company will move to commercialization in July.1 Power Factor Correction: A function which is applied to improve the efficiency of electric power transmission system.
In general, see-through LED panels look transparent when they are off because transparent electrodes are used for both of their positive and negative electrodes. There are many LED panels that become transparent when they are off. .While other see-through LED panels emit 2/3 of the light to the front side and 1/3 of the light to the back side, our panel can emit about 19/20-89/90 of the light in one direction," the company said.When a large amount of light comes out from the back side of a see-through LED panel used for a window in a room, etc, it lights up not only the room but also the outside of the room, wasting energy and possibly causing light pollution. The new panel can reduce the amount of light leaked to the outside, making it easy to realize a lighting apparatus that can be used as a transparent window during daylight hours and as a wall light during nighttime hours.
The other OLED panel exhibited by Toshiba and Toshiba Lighting & Technology is powered by using an electromagnetic induction-type wireless power transmission technology so that it can be freely moved by the user.In the past, NEC Lighting Ltd developed an OLED lighting apparatus whose design can be changed by its user. But it is equipped with electrodes used for receiving power. On the other hand, the new panel does not have electrodes, making it easier to change the position of the panel.In general, white Led high bay light panels made by using a coating process are made by applying RGB light-emitting materials in three or more stages to form RGB light-emitting layers. However, in this process, upper layers react with lower layers, destroying the layer structure.On the other hand, with the spontaneous multilayer light-emitting layer formation material, after mixing together the RGB light-emitting materials (dopants) consisting of low-molecular materials and applying it once, green, blue and red layers are automatically formed in this order from bottom up because of the effect of self-organization.
