other angle of view for led light efficiency
In routine publicity of mainstream media, the user are apt to confuse the two concepts that light efficiency the whole led equipment and single led light efficiency. analyze the relational between them we can give user a rough formula.: whole led equipment light efficiency =application environment light efficiency –convert efficiency of led driver –convert efficiency of led equipment
In the above formula, we know that there are have some factors do can influence led light efficiency .such as led equipment construction or led driver. the led equipment does not only diffuser plate, so the whole equipment light efficiency should be deducted from the convert efficiency of led driver and –convert efficiency of led equipment construction. when we talk about led efficiency ,firist of all we must clearly an important question:”under what conditions do light efficiency?”
LED was among the most influential in plant grow
The plant LED have rather a large influence over a good plant. whit the arrival of ear of led, the plant led is becoming more prevalent. the plant led has some advantage compare with traditionally lamp, the great andvantage of plant led is their fix wavelength .the controller can output different control single to control different wave -length according to plant grow’ requirement.
Every plant grow processes may require different light source. at most of plant to adopt mixing light as 450nm and 660nm. because the 450nm have contributed to the development of chlorophyll andβ-carotenoid (the main pigments absorbing the light energy ae chlorophyll and carotenoid in chloroplast of plant leaves).this 660nm may help to maintain the gains for sprouting and bloom.the red light aim for progressively performance to scale linearly.
In summary, light can influence plant grow.
To regaina sense of led features
We reacquainted led characteristic with concept as follows.
high brightness: to process can be production in high power led module, whit a higher degree of brightness.
high purity: with controlling all factors , example high quality material and process conditions. so the led has high purity and more accurate color rendition. to restore the natural color.
many type many color: nearly all the color
changing more: for more applications , because the led color-temperature is changing ,
low heat: than traditional lamp, the led can be call “cool light source”
low optical decay: because the creation of an effiecient and sustainable brightness. the led brightness should be maintained.
These features make the led more flexible than that previously traditional lamp.
