[Previous technology] Cold CathGde FluGreseent Lamp (CCFL) illuminating principle is similar to that of general illuminating lamp. The principle of illuminating is that when high voltage electricity is input from the electrode end, a few electron molecules in the tube are high-speed county electrodes, and scales are generated. Secondary electron emission, when the discharge starts, the electron collides with the mercury 2 child. The water lining is excited by the n-ray & 2537nm material light, and the light beam is applied to the filament on the wall to produce a relative color temperature. . In addition to the display, = number of ships, digital cameras and mobile phones, etc., more New Zealand display ^ one of the indispensable backlight materials. =, as the liquid crystal display gradually expands, its size is gradually increased, so the number of backlight cold cathode lamps must also increase, and the same or higher brightness.

Another multi-lamp module, as shown in Figure 1, shows that the current difference between the lamps is compensated by the series connection of the lamp m. Therefore, it will cause a large leakage current, and the efficiency is Not high, and hey, the failure mode will be _ 1 彳 炸 ,, easy to cause fire [new content] The main purpose of the above creation is to provide a piezoelectric series resonance point === the capacitance of the transformer itself The characteristic is used as a piezoelectric capacitor to form a === transformer's spectral vibration lamp circuit, which can meet the low leakage, high lighting efficiency and electricity M350943. The other purpose of this creation is; ^provide = change = traditional _ road The capacitor in the second == road is not small; it has small electrical capacity, has superior electrical performance, and can avoid the danger due to withstand voltage ===, its reliability is high, and it has a competitive advantage in the market. Each failure and overheating is provided by a piezoelectric series resonant lighting circuit that uses a series = 2 line length to make the final product ruler. Using the original 2 2 ==, the piezoelectric series resonant lighting circuit disclosed in this creation is the 'road' of the high-power piezoelectric ceramic: the light shock film is applied to the resonant point lamp~r ;^ =, complement _ depends on the balance of multiple fresh, transparent internal impedance value fixed, forming - fixed current through the lamp, when the series lamp ί:: the electrical characteristics of each piezoelectric capacitor is close, the internal impedance value is close , the current in the tube is consistent, and the tube current balance is reached. ‘Kanben’s creation of piezoelectric capacitors can be combined with independent inductors to form a resonant lighting circuit. > = Suitable for dual high-voltage lighting under full-bridge circuits. It is also suitable for half-bridge circuits. In order to further understand the purpose, features and functions of the present invention, the following detailed description is given in conjunction with the following figures: [Embodiment] May reference = Fig. 2 shows the piezoelectric type provided by the embodiment of the present creation.
