DETAILED DESCRIPTION

[0028] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0029] The output mode of the existing pulse xenon lamp power supply is that the CBB energy storage capacitor is connected in series with the inductor and then discharges the pulse xenon lamp through the thyristor. The discharge waveform is bell-shaped and the effective width of the discharge waveform is fixed. Therefore, it is not convenient to adjust the effective width of the discharge pulse output by the pulse xenon lamp power supply.

[0030] here, Figure 1 A schematic diagram of the structure of a traditional pulse xenon lamp power supply provided in an embodiment of the utility model.

[0031] Depend on Figure 1As can be seen, the discharge module 01 of the conventional pulse xenon lamp power supply includes a thyristor switch 05; the energy storage module 02 of the conventional pulse xenon lamp power supply is a CBB energy storage capacitor. Its power output mode is that the CBB energy storage capacitor is connected in series with the inductor to discharge the pulse xenon lamp 03 through the thyristor switch 05.

[0032] Furthermore, the traditional pulse xenon lamp power supply has the following technical disadvantages:

[0033] First, due to the cross-logic relationship between the modules, the modules must be in the same structural space and connected together through spatial wiring, resulting in the same structural space containing AC input circuits, output circuits, high-voltage circuits, etc., which must be physically isolated from each other. Furthermore, the functional modules containing power components such as charging modules and pre-combustion modules must consider air cooling channels, resulting in the complexity of the existing pulse xenon lamp power supply system and the difficulty of construction.

[0034] Based on this, the embodiment of the utility model provides a pulse xenon lamp power supply system and a light-emitting device. The pulse xenon lamp power supply system can drive pulse xenon lamps of different powers through the expansion of the above modular modules, reducing the complexity of the composition and the difficulty of construction.
