Improvement of high-power-white-LED lamp performance by liquid injection

Performance of a high-power-white-LED lamp is mostly hindered by its poor thermal characteristic. This characteristic is accessed by its thermal resistance. Besides thermal characteristic, light quality of a high-power-white-LED lamp is also an important issue. This parameter is accessed by its luminous efficiency. Both thermal characteristic and light quality need to be optimized in order to develop a high-power-white-LED lamp.
