LED display heat radiating plastic housing problem

1. Internal quantum power is not high, that is the case when electrons and holes recombine, photons can not have occurred generally referred to by the "current leakage" leaving the PN zone carrier recombination rate decreases. Current leakage section multiplied by the voltage That is the power of this part, that is converted into heat power, but this is not the primacy, because the internal photon power has reached 90%.
2. Not all internally generated photons emitted to the outside of the chip and ultimately converted to heat, as this is called external quantum power only reached 30%, most of them converted to heat up.
Overall, LED luminous efficiency is still relatively low, causing junction temperature rise, lower life expectancy. In order to reduce the junction temperature in order to improve the life of the LED display must attach great importance to the heat problem.
LED cooling plastic kit LED display with incandescent and fluorescent lamps used in the past is not the same, their energy loss, while significant, but most of the energy is through infrared radiation directly out less heat source; in addition to being a visual display and led Light energy consumed is converted into heat energy other energy. And because electronic goods gradually to the high-density, highly integrated development, LED products are no exception, so to solve the heat problem LED display has become the most important issue in today's LED display industry.
