LED can be customized for plant growth light

Energy saving and long life LED light source, is contributing to the agricultural production of another "wisdom" - in accordance with the preferences of crops or pests custom tailored light. This is the reporter from yesterday's China International LED industry technology forum information.

Compared with the traditional incandescent or fluorescent light, the LED light source based on the semiconductor chip "s growth is controllable. Not only is controllable, so that designers can freely arrange the rich "expression" for lighting landscape lighting -- change unpredictably is the use of this point, but also for industrial and agricultural production to derive a series of new uses, as long as the process is slightly change, can according to the needs of a long light wave spectrum in office.

Alternative to traditional light source for breeding is one of the applications. Seedlings often need to promote the growth of the artificial light. As we all know, the white light emitted by the fluorescent lamp is red, orange, yellow, green, green, blue, purple seven colors of light mixed, but the plants do not like green. Shanghai semiconductor lighting engineering and technology research center, Li Shuzhi, general manager of the Department of assessment, told reporters, compared to the preference of the plant is blue and red. "

In order to improve the efficiency of light, people usually add a "filter" in front of the fluorescent lamp, filter out the plant does not like the green light. However, whether it is directly with the fluorescent lamp or filter, there will be a part of the energy wasted, not as good as the LED plant tailored light to be effective.

The technology is also used to kill pests. If according to different pests like light to create the most appropriate hunting insecticidal lamps, not only become more effective, "manslaughter" accidents will be greatly reduced.

This LED can be done completely. "Whether it's a 440 nm blue light or a red light of about 560 nanometers, getting them is as simple as putting a little or a little salt in your cooking. Li Shuzhi said.
