Fang Zhilie, a professor at Fudan University, said recently that from the technical indicators completed in previous years, the development of semiconductor lighting technology is much faster than originally planned. The luminous efficiency Ф5 LED has reached 2491m/W, the power LED has reached 208lm/W, and the market product power LED has reached 130lm/W. The international semiconductor lighting application market is developing steadily, and the domestic market is developing rapidly.
In 2009, there were 153 MOCVD equipment in China, and the output of chips increased by 25% compared with 2008, reaching 2.3 billion yuan, and the package reached 20.4 billion yuan. Power LEDs and SMD LEDs are growing faster. In 2010, it is expected to increase to 28 billion yuan. In terms of the application market, the output value of China's LED application products in 2009 has exceeded 60 billion yuan.
Professor Fang said that China's semiconductor lighting industry has entered a period of significant historical opportunities for independent innovation and leapfrog development. In the past two years, China has become an LED full color screen, LED road traffic signal light, solar LED light, landscape lighting and other application products, the world's largest production and exporting countries and internationally important LED device packaging base, and established a complete semiconductor lighting industry. Chain, the emerging semiconductor lighting industry is being built, and the industry scale is expected to reach 500 billion yuan in 2015.
24 hours mechanical timer
Instant indicator
Min.setting time:15 minutes. Max.setting timer:24 hours
With hand switch,can be switched to operating and
setting at any time
Instructions:
1. Set program: 1 pin is equivalent to 15 minutes. Determine desired start time and push down pins until desired
off time.
For instance, if you want electrical devices to work from 8:00am to 11:00am and from 13:00pm to 17:00pm, you
just need to put down allthe pins between the three period time.
2. Set the current time: Turning the dial clockwise until the arrow pointing to
current time.
For example,if now it is 8:00 am, please turn the dial and make sure the
arrow point to 8. (See the picture.)
3. Plug the electrical device directly into the timer. Make sure the electrical
device is power-on.
4. Plug the timer into electrical outlet and the electrical device will be work
according to the setting program.
Note: = Normal Ope n = Timing
Make sure the switch on the Timing position. If it
is on the [Normal Open" mode, the electrical device is
always power-on and the timer function no work.

Application:
1. To enable high-power electric appliances to run automatically at off-peak time if there is different electricity
price according to different periods of time in some areas.
2. To use for electric appliances which need time control, such as water heaters, air conditioners, drinking
fountains, rice cookers, advertising lights and so on.
3. To control the charging time. For example, battery of electric bikes or mobile phones, storage batteries, etc.
4. Occasions which need switch on/off frequently, like interval spray irrigation for flowersand lawn, cyclical
adding oxygen to fish jar, fountains and so on.
5. Home safety precautions and lighting.
Caution:
1.D o not exceed the maximum ratings of the timer.
2.M ust reset the current time after power failure.
3.D o not plug the timer directly into the working electrical appliances.
4.U nless changing the setting, keep the program same every day.
5.D o not disassemble timer by yourself. Professionals service are needed for maintenance.
6.T his item is only for indoor use.
