What is the mainstream of the development of chip technology for semiconductor lighting?
With the development of semiconductor LED technology, its applications in the field of lighting are also increasing, especially the emergence of white LEDs, which has become a feature of semiconductor lighting. However, the key chips and packaging techniques still need to be improved, and the chips must be developed towards high power, high light efficiency and reduced thermal resistance. Increasing the power means that the current used by the chip is increased. The most direct solution is to increase the size of the chip. Now the common high-power chips are about 1mm × 1mm, and the current is 350mA. Due to the increase of the current used, the heat dissipation problem has become a prominent problem, and now the method of flip chip is basically 350mA. Due to the increase of the current used, the heat dissipation problem has become a prominent problem, and now this problem is basically solved by the method of flip chip. With the development of LED technology, its application in the lighting field will face an unprecedented opportunity and challenge.
