[Prior Art] In the prior art, the development direction of the electronic ballast has progressed from driving a single lamp in the past to driving a plurality of lamps of the same type. In addition, the electronic ballast is further developed toward miniaturization and intelligent control with the evolution of the integrated circuit (1C) technology. However, with the diversified development of light source types and the development and production of new light sources, the light source type can be roughly divided into three types of light sources, one of which is a light source with electrodes, such as a fluorescent light source (T5, T6, T8, etc.) , compact fluorescent tube, complex metal source, cold cathode source and il source, and the filament in the tube is regarded as a heatable electrode; the second is an electrodeless tube source, such as an electrodeless lamp, etc. And, its three-series solid-state semiconductor light source, such as a light-emitting diode. When the user wants to replace the above-mentioned new light sources, the corresponding electronic ballast replacement must be performed synchronously, that is, different light sources have corresponding driving modes. For example, there is no filament in the illumination structure of the electrodeless lamp and the LED illumination source, and the drive mode of the filament-free source is significantly different from the conventional method of driving the filament source. Furthermore, when the user uses two or more different types of light sources, the user must use two or more corresponding electronic ballasts, which is very inconvenient for the user's use cost and space. 3 201242434 There is a need to provide a usable electronic ballast that solves the problem of multiple light sources that are missing from conventional techniques.

Compared with the prior art, the multi-source universal electronic ballast of the present invention uses a single electronic ballast to drive one or more light source type light sources to provide a user who can elastically drive the electronic ballast without replacing the electronic ballast. The type of light source you need. Wherein, the electronic ballast of the present invention can provide a constant current corresponding to the light source according to the type of the light source installed by the user. In addition, the multi-source universal electronic ballast of the present invention may include the following advantages: (a) The electronic ballast of the present invention solves the different driving conditions of different kinds of light sources in the prior art (for example, preheating, high voltage starting is required) The protection conditions, such as protection, result in the lack of integration, that is, the invention can drive different kinds of light sources with different driving conditions.

[Embodiment] .R*. 5 201242434 In order to fully understand the object, features and effects of the present invention, the present invention will be described in detail by the following specific embodiments and the accompanying drawings. Referring to FIG. 1, a block diagram of a multi-source universal electronic ballast according to an embodiment of the present invention. In Fig. 1, the multi-source universal electronic ballast 2 is provided for selectively driving one or more light source types of light sources 4. The light source type of the light source 4 can be at least one of a lamp source having an electrode, a tube source without an electrode, and a solid-state semiconductor light source. The multi-light source universal electronic ballast 2 includes an input unit 6, a conversion unit 8, a current unit 10, and an output unit 12. The input unit 6 is configured to receive an external power source PW, and the power source PW may be direct current (DC) or alternating current (AC). For example, the direct current system may be derived from a power supply, a battery, a solar battery, etc.; and the alternating current system The exchange frequency can be provided for the mains. It is 100-300 Hz of 100-300 volts of this alternating current and the like. The conversion unit 8 is connected to the input unit 6, and the conversion unit 8 receives the power source PW and generates a corresponding voltage and current VI. Here, the conversion unit 8 is capable of converting between alternating current and direct current, such as alternating current to alternating current, alternating current to direct current, direct current to alternating current, and at least one of direct current and direct current. Taking AC to DC as an example, the conversion unit 8 provides full wave rectification or half wave rectification for AC to DC conversion. In addition, the conversion unit 8 also provides a direct output of the voltage current VI of the power source PW to the current unit 10. For example, the conversion unit 8 can be a wire. The current unit 10 is connected to the light source 4 and the conversion unit 8, and the s 6 201242434 current unit it 10 is used to generate a constant current FC, and the corresponding constant current FC is generated according to the light source type of the light source*. In other words, the constant current FC output 'received here' refers to a current that can be outputted to the output unit 12 to drive the light source 4. Wherein, the light source 4 has the constant current FC' that is driven by the same and should be (4), and the constant current % can be made difficult by the automatic or manual adjustment method for the constant current FC, so that after the adjustment The constant current FC is sufficient to drive the light source 4. In the embodiment, the 'S current current single 7C 10 further includes at least one of the ballast inductance L and the starting capacitance C, as shown in Figs. 4-7. The output unit 12 is connected to the light source 4, and the output unit 12 is connected to the current unit 1B, and the constant current FC is output to the light source 4 by the output unit 12, for example, the output unit is 12 Can be an output terminal or an electrical connector. Referring to Fig. 2, there is shown a block diagram of a multi-source general-purpose electronic stability f according to another embodiment of the present invention. In Fig. 2, in addition to the units referred to in the above embodiments. The multi-light source universal electronic ballast 2 further includes the driving module 14 for connecting at least one of the current unit 10 and the output unit 12, and the driving module 14 is according to the light source 4 For the type of light source, the current unit 10 is adjusted to output the corresponding constant current Fc to the output unit 12. The driving module 14 determines the light source type of the light source 4 according to the electrical state of at least one of the filament impedance of the light source 4, the light source voltage, the light source current, the preheating, the high voltage starting, and the subsequent stage switching. In addition, the multi-source universal electronic ballast 2 may further include at least one of a protection unit force rate factor correction unit, a half bridge spectrum conversion unit, a lamp preheating 201242434 start unit, and a frequency adjustment unit. Therefore, the driving module 14 can integrate the driving mode of the light source 4. The integrated manner is as follows: (1) When the multi-light source universal electronic ballast 2 of the present invention is connected to the preheating type lamp In the case of a light source and a non-preheating type light source, the non-preheating type light source can be completely turned on after the preheating period of driving the preheating type light source. In other words, the non-preheating type light source undergoes a warm-up phase, and the difference is that the driving brightness of the non-preheating light source in the preheating stage is darker than that of the non-preheating light source after the full driving. In an embodiment, if the identification of the light source type of the light source is performed in advance using the smart wafer, all the light sources do not need to have a warm-up time state, and when the right light source needs to be preheated, the preheating can be performed. . Wherein, the smart chip system can be disposed in the electronic ballast. (2) The short-circuit or open-circuit protection of the light source of each light source type is basically the same, so integration can be performed. In addition, the filament burnout protection system can be used to provide a circuit judgment according to an open circuit phenomenon formed by the filament being blown; and, the terminal of the filament can be short-circuited to connect the filamentless light source to solve the conventional electronic Ballasts are considered to be incapable of integration. (3) The traditional lamp system needs to be activated by a starting capacitor to perform high voltage. However, the solid state semiconductor light source does not require high voltage startup. Although the startup capacitor does not need to be present in the circuit of the solid state semiconductor light source, the startup capacitor may not be negligible when integrated with a variety of light source types. If the starting capacitor is needed
