Practice has proved that

 Practice has proved that the limitations of the optical efficiency is the main reason for the led  MR16 LED Lamp junction temperature rise. At present, the growth of advanced materials and components manufacturing process has enabled led pole most of the input energy is converted  8mm LED Flexi into light radiation, however, because the LED chip material with the surrounding medium, compared with a refraction coefficient of the much larger, resulting in the pole chip internally generated most of the photons (> 90%) can not 10mm LED Flexi be successfully overflow interface, the total reflection occurs in the chip and the media interface, returns inside the chip, and multiple internal reflections final absorption chip material or substrate, and changes in the form of a lattice vibration into heat, prompting the junction temperature rise.
