new characteristics in the led research field
The high power led has its new features in the new era. now ,user can do using nanosecond pulses to drive led. the high power led work well even if under terrible environment.when we know that the characteristics exist, we  we are easier to control led bright and led color by dynamic manner. meanwhile the dynamic change and digital control of high power led probably easier to implement.so its new high power led are well equipped to deal with new characteristics.the application domain gradually changes.for example, the new characteristics also shows  how to implement the architecture.constructions lighting can get better fusion result.
The high power led and the building lighting complement one another, constitute the urban night scene picture together.

Why engineer chose this LED as your plant growing design?

Through the study and investigations, we have seen that LED devoted her all life to the cause of agricultural production. it is because of this, farming is beginning to be Intelligentization . When compared to traditional Incandescent or fluorescent lamps . the greatest advantages of this LED are exact controllability of wave length .
The LED could be launching light of the arbitrary band.
The is light mainly mixed by the red, orange, yellow, green, green, blue and violet when using fluorescent and incandescent as light source, some plant don’t like the green light;
There is, however, a simple solution to this problem when we have this LED.

various types of the led

There are three types of led.

1, DIP low-power led : straw hat LED , Flat led . All this was DIP low-power led.

2,SMD are generally divided into（3020/3528/5050 These are front light led）/1016/1024 These are side light led.

3,high power led: These led types are each defined differently and each having its own photoelectricity parameters. ,high power led and commonly SMD led many similar appearance ,if high power led is no heat sink(general use for hexagonal heat sink), high power led source is circular.. compared with small power led which high power led is more looks brighter.

led with applying the led television

Led in a modern engineering has been used widely. led televsion among others. led is doing very well in led television.today let’s talk about led television parameters. these result give us confidence that the led is good and important resources for important fields.

1,PIXEL
The pixel is single light point. “pixel” is the abbreviation of “pictureelement”.

2,PITCH
PITCH is center distance of adjacent pixels. the smaller pitch is, the smaller visibility distance is.

3,Resolution
Means the total number of pixel, we are going to label this as width * height. for example 800*600.

4,Brightness
The brightness is import parameter for led products. this candela (millicandela) want you to know that how to express this led brightness. add up all the light in one square metre, we get the per unit brightness.

5,White balance to calibrate the white balance.
The red light, green light and blue light  must keep nature in balance so that to get accurately restore the color. other words: white must be white, and not pink. are on in others media, in order to take that white light(often described as the 6500K) adjust the white balance to make that one of the red light, green light and blue light to trying to brightness down. you may have to experiment with this to achieve a white balance.

Talking about the cob led
LED is a semiconductor luminescence device, because of its electricity features, it will used to generate light,  when the voltage is loaded on it.
The input voltage is 3V and input current is 20mA for a certain led.there are many types of led.on the involution, this 3V and 20mA development tendency is the extension of its functions, the led parameter can be evolution in a variety of parameter led.  the 6V,9V led is connected with serial-in parallel-out and they have a stronger light energy.and in the background there needs to be a more professional led device. it name is COB led. COB also is led,designed around the same principle.
There are many led were encapsulated in led device for protection. the cob could have a big operation voltage and current than in single led.
