Embodiment
This digital high-intensity gas discharge lamp adapter not only rolls into one ballast and trigger, but also can adjust the control needs that its operational factor satisfies multiple high-intensity gas discharge lamp by built-in microcomputer chip, different fully on technical concept with existing analog circuit product, therefore we are called digital high-intensity gas discharge lamp adapter with it, abbreviate the gas discharge lamp adaptor as.
As shown in Figure 1, it is by power output module, the device power supply (DPS) module, system's detection module, with the microcomputer chip is microcomputer controlling module (the abbreviating microcomputer controlling module as) composition of core, wherein power output module is connected with high-intensity gas discharge lamp, the power supply supply that needs when providing the HID light source to use, the device power supply (DPS) module provides the power supply supply to power output module and microcomputer controlling module and system's detection module, system's detection module is gathered the operational factor of power output module and device power supply (DPS) module, and be transported among the microcomputer controlling module, microcomputer controlling module is made up of microcomputer chip and supporting with it peripheral circuit, and it is the control maincenter of this digital high-intensity gas discharge lamp adapter.Microcomputer chip receives all kinds of parameters from data acquisition module, after finishing a series of flow chart of data processing such as identification, judgement, processing, result is fed back to power output module, according to adjusting its operational factor, make this digital high-intensity gas discharge lamp adapter remain at best operating state by power output module from the instruction of microcomputer.
Power output module plays crucial effects among the process of using the HID light source.Itself has trigger and two kinds of functions of ballast concurrently, but unlike the prior art be, it has multi-stage ignition and random start function among start-up course, also have multiple functions such as with an automatic light meter, power control, automated power tracking, " acoustic resonance " inhibition in running.These functions are to realize by circuit structure shown in Figure 2.As shown in Figure 2, power output module comprises assemblies such as ignition coil, multi-stage ignition generator, semibridge system fet power switch, output frequency synthesizer, wherein ignition coil is connected with the multi-stage ignition generator, the semibridge system fet power switch is connected with the output frequency synthesizer, ignition coil is connected with the HID light source respectively with the semibridge system fet power switch, and multi-stage ignition generator and output frequency synthesizer are then adjusted the instruction of bus reception from microcomputer chip by data.It is a level converter that above-mentioned data are adjusted bus.Because the operating voltage of microcomputer chip and each electronic component is also not quite identical, microcomputer chip can not directly be connected with each element, is connected with each element and must adjust bus by data again.Level converter is a primary element commonly used in the digital circuit, as known technology, has not just given unnecessary details at this.In addition, in Fig. 2, also indicate a part of circuit of system's detection module.Output sampling device is connected with the HID light source, to gather the parameter of its running status, is transferred to after the data that the collect process analog/digital converter among the operation information data/address bus in system's detection module.
