Question:admin
According to luminous flux (lumens) and the radiant flux (watts) the following equivalent relations: where, Km = 683 lm / w, is the luminous flux of the scale, the scale is the radiant flux. 1W of radiant flux that is the case in the best (blackbody radiation) may have 683lm luminous flux. So, even if the LED light efficiency to 200lm / w, nor can all the energy into light output, while the rest is converted into heat. LED lamp heat problem in the long run will be a long-term problem.
