Definitions
- the present invention relates to a high-voltage generating transformer for a discharge lamp lighting device suitable for a discharge lamp that supplies a large current, such as a high-intensity discharge lamp that does not use mercury.
- a high voltage generator In order to light a high-intensity discharge lamp (HID bulb) used for a vehicle headlamp, a high voltage generator generally called “igniter (IGN)" is required. Use a high voltage generating transformer. Examples of conventional high voltage generating transformers for discharge lamp lighting devices include the following conventional examples.
- this conventional example is a high-voltage generating transformer in which a primary winding is wound on a secondary winding in which a rectangular wire is wound edgewise on a single rod core. It is characterized in that the length of the axial direction in which the outer shape of the winding wire is small can be shortened by directly assembling the secondary winding with a flat wire to the Ni-Zn ferrite core with high resistance.
- the high voltage generating transformer of Conventional Example 2 is similar to the structure of Conventional Example 1 (Patent Document 1).
- This Conventional Example 2 is the conventional example 1 in which the core is treated as an insulator. On the other hand, the core is treated as a conductor. For this purpose, it is necessary to ensure insulation between the core and the secondary winding, and in order to provide insulation characteristics to the bobbin for the secondary winding, the bobbin on the side where the high voltage of the secondary winding is generated It is thick.
- the conventional example 1 and the conventional example 2 are basically the same in the configuration of the primary winding and the secondary winding (see, for example, Patent Document 2).
- this conventional example has a round wire on a bobbin divided into several sections.
- this conventional example is a high-voltage generating transformer for high-intensity discharge lamps that do not use mercury, which will be described later. This is the result of winding the primary winding on the secondary winding of the wound flat wire.
- a large current is required to light up a high-intensity discharge lamp that does not use mercury.
- the secondary winding is divided, the secondary winding on the low voltage side is superimposed on the outside of the secondary winding on the high voltage side, and the primary winding is further provided on the outside.
- the examples also show the idea that the thickness of the bobbin, which is a partition wall for ensuring withstand voltage, is changed to a stepped shape or a wedge shape according to the applied voltage (for example, see Patent Document 4).
- Patent Document 1 Japanese Patent Application Laid-Open No. 2002-93635
- Patent Document 2 Japanese Patent Laid-Open No. 2005-322515
- Patent Document 3 Japanese Patent Laid-Open No. 2001-257087
- Patent Document 4 Japanese Patent Application Laid-Open No. 2004-111451
- a conventional high voltage generating transformer for a discharge lamp lighting device is configured as described above, and is realized and commercialized by several methods.
- the high voltage generating transformers of the conventional example 1 (patent document 1) and the conventional example 3 (patent document 3) are both high-intensity discharge lamps using mercury (HID bulbs to be referred to as “conventional bulbs”). This technology was fully completed as a high voltage generation transformer for igniters.
- Hg-free bulbs High-intensity discharge lamps (hereinafter referred to as “Hg-free bulbs”) have been put into practical use. Since this Hg-free valve has a valve current approximately twice that of the conventional valve, when designing a new igniter for the Hg-free valve, the technology corresponding to the conventional noble is sufficient as shown below. Since it is not possible to cope with it, it is necessary to make the igniter even more sophisticated.
- the rated power of both the conventional bulb for vehicle headlamps and the Hg-free bulb is 35 W.
- the rated current of the Hg-free bulb is 0.8 A
- the rated current of the conventional bulb is 0.4 A
- the rated voltage of the Hg-free bulb Is 42V is 85V.
- the high voltage generating transformer used in the igniter for the Hg-free valve corresponds to the energization current approximately doubled as described above, and the heat generated by the loss is compared with the heat generated in the conventional valve.
- the high voltage generation transformer for Hg-free valves is required to have a large current specification compared to the conventional one for valves.
- explanation will be given on the case where each of the above-mentioned conventional examples is made to correspond to this large current specification.
- Patent Document 1 it is necessary to increase the width or thickness of the secondary wire flat wire in order to cope with a large current.
- a configuration using a rolled secondary winding it can handle edgewise winding.
- the ratio between the width and thickness of the flat wire is limited, and it is not possible to expand the width only while maintaining the thickness of the conventional valve and maintaining the full length of the high-voltage generating transformer.
- the wire expands in the diameter direction of the high-voltage generating transformer and expands in the axial direction (longitudinal direction of the core), and the size of the igniter is enlarged, making it impossible to construct an igniter of the same size as that for conventional valves. There is a problem.
- Patent Document 2 in the case of Conventional Example No. 2, in order to cope with a large current, by increasing the thickness of the secondary rectangular wire, Because the distance to the shoreline (especially the secondary shoreline located on the opposite side of the primary shoreline) is increased (the core also extends), the magnetic flux generated by the primary shoreline is extended in the middle of the secondary shoreline. It becomes easy to leak. If the magnetic flux generated by the primary winding leaks in the middle of the secondary winding, the magnetic flux generated by the primary winding will not reach the secondary winding at a position away from the primary winding. The secondary winding in the position where the magnetic flux cannot reach does not function as a transformer. Therefore, there is a problem that the Idanitanus voltage generated on the secondary winding side becomes low, and sufficient characteristics cannot be obtained as a high voltage generating transformer.
- the secondary winding of the high voltage generating transformer expands in the diameter (diameter) direction and extends in the axial direction, so that the diameter direction from the primary winding to the secondary winding (the center of the secondary winding) The distance between the two layers is separated from the axial distance.
- the magnetic flux generated by the primary winding easily leaks in the middle of the radially expanded winding or in the axial direction of the winding. Become. If the magnetic flux generated by the primary winding leaks in the middle, there will be a problem that sufficient output cannot be obtained as in the case of the conventional example 2 above.
- Example 4 corresponds to the Hg free valve as described above, and is a problem corresponding to the Hg free valve as described above, that is, a vehicle. It was proposed to improve the performance of the igniter by solving the problem of the size of the igniter that fits in a limited space for use or the deterioration of the electrical performance (characteristics) of the high-voltage generating transformer. It is.
- the secondary winding and the primary winding should be arranged so that the magnetic flux does not leak from the gap between the primary windings.
- the secondary winding is divided into 2 bobbins in the diameter (diameter) direction, and the primary winding is divided into two It can be said that the configuration of a three-layer high-voltage generating transformer inserted between the windings is optimal. This three-layer structure shortens the axial length.
- the present invention has been made to solve the above-described problems, and does not significantly increase the size of the igniter, and reduces leakage of magnetic flux generated from the primary winding, so as to link to the secondary winding.
- the purpose is to obtain a high voltage generating transformer.
- a high voltage generation transformer for a discharge lamp lighting device includes a rod-shaped core, a secondary winding bobbin that is divided into a plurality of sections, and the core is disposed at the center, and A secondary winding that is divided into a plurality of sections of the secondary winding bobbin, wound, a primary winding bobbin disposed on the outer periphery of the secondary winding, and the primary winding bobbin
- the primary winding bobbin is thicker on the side where the potential difference between the primary winding and the secondary winding is higher and thinner on the lower side. As described above, it is changed for each section of the secondary winding or for each of a plurality of sections.
- the potential difference that increases the thickness of the primary winding bobbin is low
- the bobbin thickness is changed for each section or multiple sections of the secondary winding so that the thickness is reduced, the insulation of the primary and secondary windings is ensured.
- the leakage of the magnetic flux generated by the primary winding is reduced, and the generated magnetic flux is linked to the secondary winding, thereby improving the characteristics of the high voltage generating transformer for the discharge lamp lighting device. It is possible to respond to lighting of the Hg-free valve.
- FIG. 1 is a structural explanatory diagram showing a configuration of a high voltage generating transformer for a discharge lamp lighting device according to Embodiment 1 of the present invention.
- FIG. 3 is an explanatory diagram of a magnetic flux model of a high voltage generating transformer for a discharge lamp lighting device according to Embodiment 1 of the present invention.
- FIG. 4 is a structural explanatory diagram of a primary winding bobbin used in a high voltage generating transformer for a discharge lamp lighting device according to Embodiment 1 of the present invention.
- FIG. 5 shows a high voltage generating transformer for a discharge lamp lighting device according to Embodiment 2 of the present invention.
- FIG. 5 is a structural explanatory diagram of an example of a primary winding bobbin.
- the power supply unit 21 includes a step-up direct current (DC) Z direct current (DC) converter and the like, and generates a voltage Ea and a voltage Eb having predetermined values based on a direct current power source such as a notch.
- the generated voltage Ea is applied to the capacitor 23 through the resistor 22 to charge the capacitor 23.
- the gap switch 24, to which the voltage across the capacitor 23 is applied breaks down and turns on, and the discharge voltage of the capacitor 23 Applied to the primary winding of the high-voltage generator transformer 1.
- a high voltage pulse is generated on the secondary winding of the high voltage generating transformer 1, and this high voltage pulse is applied to the HID valve 25.
- HID valve 25 startss and starts to discharge by breakdown between the electrodes. After starting the discharge, the HID valve 25 shifts to steady lighting by applying the voltage Eb from the power supply unit 21.
- the high voltage generating transformer 1 has a function of generating a high voltage pulse on the secondary winding based on the voltage applied to the primary winding and starting the HID valve 25.
- a capacitive component (Cs) 26 due to stray capacitance and parasitic capacitance exists as a load, and this capacitive component (Cs) 26 is charged when a high-voltage pulse is generated.
- a capacitive component (Cs) 26 exists as a load in an actual high voltage generating transformer, and flows to the secondary winding due to this capacitive component (Cs) 26.
- the current acts to counteract the magnetic flux generated by the primary winding. Therefore, there is a capacitive component (Cs) 26.
- the magnetic flux generated by the primary winding becomes the magnetic flux shown by the solid line in Fig. 3, but due to the canceling action of the capacitance component (Cs), the magnetic flux shown by the broken line in Fig. 3 is obtained.
- the magnetic flux generated by the primary winding leaks further, and the magnetic flux generated by the primary winding always becomes difficult to interlink with the secondary winding.
- the magnetic flux that cannot be linked to the secondary winding is concentrated between the primary winding and the secondary winding, and may pass through the primary winding as shown in part C of Fig. 3.
- the primary winding is wound in parallel and the gap between the wires is narrowed to reduce the magnetic flux leaking from the gap so that the magnetic flux generated by the primary winding is guided to the secondary winding.
- the high voltage generating transformer 1 has its primary winding 15 arranged outside all sections of the secondary winding 13, and the isolation wall between the primary winding 15 and the secondary winding 13 is separated. Decrease the thickness of the bobbin 14 for primary winding. However, it is possible to reduce the thickness of the low voltage side (14a) where the potential difference between the primary and secondary windings is almost the same, but the high voltage that requires high withstand voltage is required. The thickness of the primary winding bobbin 14 on the side facing the secondary winding 13 (high voltage side 14b) where the is generated must be increased.
- the primary winding bobbin 14 has a low potential difference between the primary winding 15 and the secondary winding 13, and the low voltage side (14a) is made as thin as possible.
- the primary winding 15 is wound on the outer periphery of the primary winding bobbin 14 of this structure so as to cover the entire area of the secondary winding.
- FIG. 1 A specific example that satisfies the above conditions is the shape shown in Fig. 1.
- the thickness of the primary winding bobbin 14 varies with the voltage of the secondary winding 13 for each section. Change to steps according to the section.
- Figure 1 shows this staircase shape on the inner diameter side (inner circumference side) of the primary bobbin 14
- Figure 4 An example of this structure is shown in Figure 4.
- FIG. 4 is an explanatory diagram of the structure of the primary winding bobbin 14 and shows a partially cut-out external perspective view. As shown in FIG. 4, the inner diameter side (inner circumference side) of the primary winding bobbin 14 is stepped, and the outer diameter side (outer circumference side) is constant (flat). This facilitates winding of the outer peripheral primary winding 15 and is preferable in terms of work.
- the characteristics of the high voltage generating transformer 1 can be further improved.
- FIG. 1 is changed to a stepped shape corresponding to each section of the secondary winding 13, but it corresponds to each of a plurality of sections. Then you can change it to a staircase.
- this step shape is provided on the inner diameter side (inner circumference side) as shown in FIG. 1, it is provided on the outer diameter side (outer circumference side) of the primary winding bobbin 14, and the inner diameter side (inner circumference side) is provided.
- the structure may be constant (flat). In this case, the force that makes the primary winding 15 difficult to wind.
- the same effect as the structure in which a step shape is provided on the inner diameter side (inner circumference side) can be obtained.
- the thickness (E) of the above-mentioned facing portion of the secondary winding bobbin 1 2 required to ensure this withstand voltage is higher than that of the primary winding 15 located on the outer periphery of the high voltage section of the secondary winding 13. It is approximately equal to the thickness (D) of the primary winding bobbin 14 required to secure the withstand voltage between the secondary winding portion 13b of the voltage section. Therefore, the thickness of the secondary winding bobbin 12 becomes thinner for each section of the secondary winding 13 and the other becomes thicker. That is, the outer peripheral side of the secondary winding bobbin 12 is formed in a stepped shape for each section in the same manner as the inner diameter side (inner peripheral side) of the primary winding bobbin 14.
- the gap between the inner diameter of the primary winding bobbin 14 and the outer circumference of the secondary winding 13 is the same in any section of the secondary winding 13, and the magnetic flux is maintained while ensuring the withstand voltage of each part. It is possible to construct a shoreline with little leakage, and to further improve the characteristics as a high voltage generation transformer.
- the thickness of the secondary winding bobbin 12 is changed with the same structure as that of the conventional example 2 (Patent Document 2), but the configuration shown in FIG. The configuration has a primary winding 15 covering 13 and the idea is completely different in the arrangement of the primary winding and the secondary winding of the single-layer winding in the conventional example 2.
- the primary winding 15 will be described. From (b), the primary winding 15 is wound with a plurality of wires arranged in parallel.
- the primary winding 15 shown in FIG. 1 is an example in which six wires (six small round marks 15a) are wound in parallel.
- Patent Document 1 the idea of using a wide rectangular wire or a thin conductive foil for the primary winding is shown.
- the current will not flow uniformly and evenly.
- this thin conductive foil if this thin conductive foil is developed, it is equivalent to a rectangular electrode. If a current is passed through two points of the rectangular electrode, the current will be concentrated in the shortest distance path in the rectangular surface, and magnetic flux will be generated except for the shortest distance where no current flows. This results in the leakage of the magnetic flux.
- the secondary winding is wound by being divided into a plurality of sections of the secondary winding bobbin 12 in which the core 11 is disposed at the center.
- the high voltage side 14b having a high potential difference between 13 and the primary winding 15 wound around the primary winding bobbin 14 disposed on the outer peripheral side of the secondary winding 13 is the primary winding 14b. Thicken the thickness of the primary bobbin 14 for each section or multiple sections of the secondary winding 13a so that the thickness of the low-voltage side 14a with a small potential difference is increased. Since the primary winding 15 is wound around the primary winding bobbin 14 so as to cover the entire area of the secondary winding, the high-voltage side 14b with a high potential difference is used. While the voltage is secured, the leakage of the magnetic flux generated by the primary winding 15 is reduced, and the generated magnetic flux is linked to the secondary winding 13. It is possible to further improve the characteristics of the transformer 1 may correspond to the lighting of the Hg-free valve
- the secondary winding bobbin 12 is configured such that the high voltage side of the secondary winding 13 has a thin bobbin thickness and the low voltage side has a thickening of the bobbin thickness. Since the thickness of the bobbin is changed stepwise for each section or for each section, the withstand voltage between the output terminal 16 and the secondary winding portion 13a of the low voltage section can be secured. On the other hand, a winding configuration with less magnetic flux leakage between the primary winding 15 and the high voltage generating transformer 1 can be improved.
- the primary winding 15 has a configuration in which a plurality of wires are wound in parallel, The gap between the wires is reduced, and the magnetic flux that passes between these wires can be reduced, and the magnetic flux generated by the primary winding is increased, leading to the secondary winding. Can be improved.
- the inner surface of the recess 14c provided at the terminal portion of the primary winding bobbin 14 and the outer surface of the hook-shaped protrusion 17a of the insulating wall provided in the case 17 are opposed to each other. Since the hook-shaped protrusion 17a is embedded in the recess 14c, the low-voltage primary winding 15 and the secondary winding 13 that outputs a high voltage 13 lead-out portion 13c or the tip 16a of the output terminal 16 As a result, the creepage distance between the two can be increased, the withstand voltage between them can be secured, and even in a narrow space of the small high-voltage generating transformer 1, breakdown due to discharge can be avoided.
- the high voltage generating transformer 1 having the above-described configuration is capable of supporting a newly commercialized Hg free valve, and has a higher performance of the igniter.
- the high voltage generating transformer 1 having this configuration Can be applied to a high voltage generating transformer for a conventional valve, and a conventional igniter for a valve can be improved in performance and size.
- a primary wire bobbin having a wedge shape whose thickness changes as it reaches one end and the other end may be used.
- FIG. 5 is an explanatory view of the structure of an example of a primary winding bobbin used in a high voltage generating transformer for a discharge lamp lighting device according to Embodiment 2 of the present invention, and shows a partially cut-out perspective view.
- the primary winding bobbin has a wedge shape on its inner diameter side (inner circumference side) and a constant (flat) shape on the outer diameter side (outer circumference side) as in FIG. is there.
- the wedge shape is provided on the inner diameter side (inner circumference side) of the primary winding bobbin, instead of the outer diameter side (outer circumference side), and the inner diameter side (inner circumference side) is constant ( Even in this structure, the same effect as the structure in which the wedge shape is provided on the inner diameter side (inner circumference side) can be obtained for improving the characteristics of the high voltage generating transformer.
- the inner diameter side (inner peripheral side) of the primary winding bobbin is not wedged as shown in Fig. 5, but the bobbin is made to have a uniform thickness and has the same insulation as the primary winding bobbin. Is filled between the primary winding bobbin having a uniform thickness and the secondary winding, and when it is wedge-shaped including the shape of this filling material, the inner diameter side (inner Similar to the case of the primary winding bobbin 14 whose circumferential side is stepped, the same effect as that of the primary winding bobbin whose inner diameter side (inner peripheral side) is wedged can be obtained.
- the high voltage generating transformer for a discharge lamp lighting device leaks magnetic flux generated by the primary winding while ensuring the insulation between the primary winding and the secondary winding.
- the characteristics of the high-voltage generating transformer can be further improved by intermingling the generated magnetic flux with the secondary winding, so that the Hg-free valve with an igniter of roughly the same size as that of the conventional valve can be used. Suitable for use in compatible vehicle headlights.
