Semiconductor lighting in this emerging field appearance and professional knowledge in power electronics, optical and heat pipe neo-confucianism (mechanical engineering) of the three areas of engineer become popular talent. At present, in three fields are experienced engineers are not much, and that usually means a system engineer or the entire product engineer background and three relevant fields, and they should as far as possible and other areas of engineers collaboration. System engineer will often take their original stress field habit or experience design work, this and a major study digital system of electronic engineer become solve power management encountered similar problem: they can rely on pure simulation, not the power to do test test is directly in the circuit board wiring, because they are not aware that: switching voltage regulators need to carefully check the circuit board layout; In addition, if not in the test, the actual efforts and simulation agree.

In the process of design LED panel lights, when the system architecture engineer is an electronic power experts, or power source design is contracting gave an engineering company, some standard power source design of common habit will appear in the design of LED drive. Some habits are very useful, because in many ways and LED drive traditional constant pressure source very similar. The two types of circuit to work in a big range of input voltage and larger output power, in addition, the two types of circuits connect ac power, face dc voltage stabilizer railway or battery connection method superior different challenges.

Power electronic engineers used to always wanted to ensure that the output voltage or current of high accuracy, but lead to driving design and is not a good habit. Such as the FPGA and DSP and digital load need more low core voltage, and more strict requirements and control to prevent high ber. Theref
