Electrode fluorescent lamp was only in the 1990s , developed a new type of product , and compared to ordinary fluorescent lamps , due to the characteristics of long life , high luminous efficiency , green market prospects are generally public lighting and road lighting accepted by many companies at home and abroad and a large investment of manpower, material research and development Promise lights and electronic ballasts . However, due to the electrodeless lamp cost , electromagnetic interference ( EMI ) , heat , reliability issues such as restricted its development , application , resulting electrodeless lamp can not yet be applied widely . The paper first introduces the electrodeless lamp background and status quo at home and abroad , and then combined with the operating characteristics of the induction lamp and literature , establish the electrodeless lamp transformer model , and then through the circuit equivalent obtained electrodeless lamp LR equivalent model . The half-bridge inverter resonant circuit , inductive load and capacitive load characteristics . This article describes several half-bridge driver program , and test the chip due to the high frequency of the now the electrodeless lamp half - bridge inverter circuit work , it is difficult to find the appropriate driver chip . Analysis is given by the LC resonant circuit to determine the load characteristics , but also gives the calculation procedure of the LC resonant circuit , laid the theoretical foundation for the subsequent experiments . Taking into account the higher cost of the induction lamp through the active power tubes reuse buck power factor correction (PFC) and Class E resonant inverter , a new single-stage , single - switch electronic ballast the topological structure , the structure using only one active power tube , thus saving components and the corresponding control circuit , simplifying the structure . The article in the fourth chapter of the topology of theoretical analysis and Pspice simulation , including model electrodeless lamp and fluorescent lamp model , simulation results with the theoretical analysis of the consistency , at the same time meet the IEC 16000 class c standard . Finally, the design methods and steps given above , the trial of a 23W inductively coupled electrodeless lamp prototype , and elaborate on a prototype of the design process , including the the EMI circuit , the half-bridge inverter resonant circuit , NE555 and IR2111 driver circuit consisting of such as the design . The experimental and simulation waveforms also proved the accuracy of the model of the previous electrodeless lamp .
