. Internally generated photons emitted to the outside of the chip can not be fully and finally converted into heat, which is the main part led electronic display, because it is called the external quantum efficiency is only about 30%, most of them converted to heat up. As previously mentioned, although incandescent light efficiency is very low, only 15lm / W about Xiangfan led electronic display, but it is almost all of the electrical energy into light energy and radiate out Icheon led electronic display, because most of the Infrared radiation is so low efficiency, but it eliminates the problem of heat dissipation. LED large screen curtain is a public media Danjiangkou led electronic display, there is public service, advertising category, indicating that other categories. When we choose to play the content, you must be in agreement with the public demand, avoiding refuse to see the psychological. This is also the prevention of pollution of an LED light display large screen curtain is public media, there is public service, advertising category, indicating that other categories. When we choose to play the content, you must be in agreement with the public demand, avoiding refuse to see the psychological. This is also an important aspect of the display light pollution prevention. Important aspects.
