important parameters of LED lightingimportant parameters of LED lighting 1 Forward Current If: It refers to the positive value of forward current normal light emitting diodes when . In actual use, should be selected in 0.6 ? IFm IF less . 2 forward voltage VF: Parameters given in the table operating voltage is at a given forward current to get. Generally in the IF = 20mA when measured . Light emitting diodes in the forward voltage VF of 1.4 ~ 3V. When the outside temperature , VF decreases. 3.V...

LED recycling-a new hot topicLED recycling-a new hot topic LED has been very environmentally friendly in its production life span, but if it can be recycled and re-used, it would be more environmentally friendly. More than 95%LED can be recycled, and recycling companies will buy the old LED with low price. When LED does not contain any harmful substances, it was classified as RoHS-compliant. RoHS was passed in January 2006 in the UK.It is restrictions on electrical and electronic equipment to th...

The distinction between high-and low-power LED'sThe distinction between high-and low-power LED's With the continuous development of LED technology, people adapt to the development of large-area lighting and power growing single LED chip, currently the worlds most cutting-edge single LED can already do more than 200W power, although power can do it , but its cost and poor. Below we have several common LED, for example, to do an analysis. Currently the industry is heavily used single 0.06W power, its maximum brightness can be done 7LM...

The importance LED thermal designThe importance LED thermal design LED is a semiconductor device itself, all of the semiconductor device has a normal operating temperature requirements, including ambient temperature and operating temperature. Ambient temperature semiconductor devices generally have less than 80 degrees of normal, while the internal LED PN junction temperature reaches 140 degrees and they will fail. Normal working temperature of its own that comes out through the pin or special base, which can...
