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?”
