Nanjing Dihao Organic Optoelectronics Co., Ltd. successfully prepared the internal light extraction IES-
OLED white light illumination module, which has an energy efficiency of 111.7 lumens/watt (lm/W), setting a world record for similar devices. Recently, the China High-tech Industrialization Research Association held a results appraisal meeting in Beijing that the overall technology and system of the project has reached the international advanced level.
OLED is a kind of semiconductor device that can convert electrical energy into light energy. The energy consumption of illumination is only 1/6 of incandescent lamp and 1/2 of fluorescent lamp, which is equivalent to high quality LED lamp; OLED light quality is close to natural light, no heat radiation, It does not contain mercury and other heavy metals, and has no problems such as pollution and waste disposal. It has great health and environmental benefits.
In order to improve energy efficiency and extend product life, Nanjing Dijon has independently developed an optimized formulation of external light extraction materials containing micron particles. It is the first in the world to use a simple and inexpensive coating method to improve materials and coating processes. EES-OLED lighting device with light extraction efficiency of 80% was prepared; dark blue phosphorescent light-emitting system material and electron transport material were developed, which greatly reduced the device driving voltage and improved power efficiency; and developed the EES-OLED lighting panel production process. It has also developed key technologies such as short-circuit proof and high-reliability packaging, improved the function of OLED devices and extended their lifespan, and built a production line with a capacity of 20,000 square meters.
Xu Zheng, a professor at the Institute of Optoelectronic Technology of Beijing Jiaotong University, said that the OLED lighting module project is an independent research and development enterprise based on market demand, and is a high-tech and strategic emerging industry field supported by the state. OLED lighting is a surface light source, no ultraviolet light, soft light, uniform, no glare. Its lighting is suitable for youth eye protection lamps and military equipment and equipment with high space requirements, harsh environment, high altitude and high pressure; its good color rendering performance is very good. It is good to restore the original color of the cultural relics and protect the cultural relics. It is suitable for special places such as museums.
At present, the EU, the United States, South Korea and Japan have formulated OLED lighting development strategies, and the success of OLED lighting modules has enabled China to maintain a world-leading level in this field.
Drum
type Rice Cooker
Features
This type rice cooker is famous with drum type appearance, which
is easy operation and easy clean.
There are two type of inner pot , one type called white pot which is without non-stick but cheaper price
.another one called non-stick pot is polished with emery, Also there are two
type non-stick with different price ,it`s depending on different demands to
use.
And the inner pot cannot be burned on the stove, which will make
the pot transfigured and bad contact with the heating plate. While cooking , the
heating plate or the fuse is most likely to be burned for the bad contact of
the inner pot and the heating plate, Besides, make sure to dry the pot before
putting into the outer shell of the rice cooker ,or else the drops of water
flowing on the heating plate, will make the heating plate rusted.
Applications
Many
peoples are used drum type rice cooker for congee and soup, some of peoples are
prefer to use this type rice cooker for steaming.
