LED light output as its chip types and different method of encapsulation and other some of the differences and changes. But no a unified standard in the world to measure the brightness of it. In general amount of light-emitting LED is a light spot on the axial height value to measure, and use (MCD) candle to said. A high DuDu values LED does not mean it has high light output, to calculate the total output of light, you must take it into consideration the light Angle. LED is one type of LED chips from the point of view of a function and its epoxy resin shell of the spectral function or astigmatism. Different chips and encapsulation shell of the brightness of the leds will have different values. If two leds have the same brightness value, the bigger the light Angle is the light output. |
