The diode still has many shortcomings, such as brightness and AC drive. The limb is a forward-acting element, and its reverse bias is not able to issue a book, ^9. As shown in the figure, it is a circuit diagram of a conventional driving light-emitting diode. As shown in the figure, the driving circuit 10 directly drives the illuminating illuminating-polar body D to emit light, and the light source thus formed may have a flickering condition due to the reverse-non-lighting principle, and the blinking period is about For the eight-year flash cycle of 1/60 seconds, there is still a need for improvement. Big...lights You add mountains — 1...~The technology of a basket is shown in Figure 2. The AC driving circuit 20 includes two anti-parallel LEDs D, D2, _ ^ ^ and an I-light body in the positive and negative biases, and the IL emits light, so the flashing situation will improve. However, since the original power supply specifications are all ι 〇 volt or volt, ^ this voltage can not be H (four), so the power supply needs to be stepped down. Jun Fang can be used for the light-emitting diode. Figure 3 shows an AC 2 'transformer T and a light-emitting diode DI.D2 including a 1264136 power supply. Due to the anti-pressure effect of the transformer, the light-emitting diode D1., D2 can properly emit light. However, the use of transformers increases the cost of the drive circuit, so it is indeed desirable for the drive circuit of an AC-driven multi-light-emitting diode to be: if the drive circuit can be combined with an electrostatic protection component to achieve electrostatic protection. The AC-driven multi-light-emitting diode structure thus formed is a competitive structure. SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide an AC-driven multi-light-emitting diode structure having a surge protective substrate, comprising a plurality of light-emitting diodes, including a first group and a second a plurality of light-emitting diodes connected in parallel with each other, the first group of light-emitting diodes being connected in series in a first specific direction, the second group of light-emitting diodes being connected in series in an opposite direction; a driving circuit, and the first and the second Two sets of light-emitting diodes are electrically connected, and an AC power source is electrically connected to the two ends of the second group of light-emitting diodes through the driving circuit, wherein the plurality of light-emitting diodes are a light-emitting diode flip-chip structure formed by one and a surge protective substrate, wherein the driving circuit is located on the surge protective substrate, wherein the surge protective substrate is used to make the plurality of light emitting diodes It is not damaged by surges such as electrostatic discharge. In one embodiment, the protective substrate comprises a zinc oxide substrate, or a set of Zener diode substrates, or a thyristor (SCR) substrate, or a metal/insulation layer/metal (Μ I Μ ) three-layer structure.

The protection of the 1264136 base plate can be beneficial, the b-tf, the 叱Nanfan body is not protected by the static series connection can be resistant to the ancient heart .3⁄4 光二, Abao, and can increase the brightness. 3. Forward and reverse soils, so energy costs can be saved. σ句^ [Embodiment] The invention discloses the invention - the insertion of a light-emitting diode of a dog-wave protective substrate, the Γ/T heart and the 冓乂 冓乂 私 以In the description of the embodiments, the related drawings are attached. Μ逞' Figure 4 shows the schematic diagram of Shi Dai. As shown in the figure, the light-emitting diode of the light-emitting diode is as follows: several light-emitting diodes: the road 40 contains ~AC power supply Α The light-emitting diode 2: not set in the same two, the diode D is mutually In the middle of 5 Hai, the path P1, P2 is reversed.

Therefore, it is possible to reach the two-inch LED of the AC-driven LED, and the driving structure of the driving circuit shown in Figure 4 is η. "The Ί and illuminating diode substrate electrode 52 is not shown. IX ^ -tt ^ ^ . Private D, in which the zinc oxide substrate 5 seeks the light-emitting diode 0 to be protected from static electricity, and the details thereof are as follows: qi = two inventions, five of the other ones - patent application number 941 194 〇9,-',,,,,,,, protect a compound semiconductor from electrostatic discharge [ESD J; polar body light, multi-reference example and complex tandem illumination for direct use. Path light; The moving line system uses the 1264136 which can be used to refer to the title. At this time, the zinc oxide base is not like the conventional drive, and the drive line is provided on the inside and inside. In addition to the drives, the electrodes 52 and the drive paths are fabricated on a printed circuit board. This is done, that is, the perforation and the connection of the surface for the endurance can be made by other means to prevent static electricity from being broken. In addition, the zinc oxide substrate 5] is equivalent to the use of a protective substrate of an equal number of 5% of the light-emitting diode, such as a metal/insulator/metal two-nano-substrate substrate, and a thyristor (S(:R) substrate. Metal/insulation layer/metal Μ%) Two-layer structure capacitor flip-chip substrate, etc., especially having a capacitance, and thus with the illuminating ~i]Vl) two-layer structure capacitor flip-chip substrate itself enhances the stability of luminescence. The polar body itself forms a rectifying and filtering effect, and Fig. 6 is a schematic view showing an example of the present invention. As shown in the figure, the ▲~light-emitting diode AC drive circuit is implemented and the light-emitting diode D, the bean-form 碡 drive circuit 6 〇 includes an AC power supply AC path, and the light-emitting diodes are: same as the bridge rectifier. On the driving power, and part of the two are respectively located in the light-emitting diode path. 1,. 2 on. When AC power supply AC is provided: the light-emitting diode paths P1 and P2 are obtained - so when the voltage is in a positive voltage cycle, the I-light body D on the P1 path emits light, p ? AC power supply AC The electricity; silly light-emitting diodes do not emit light; when -^ η ^ ?' in the negative voltage cycle, the Ρ2 path emits a polar body D, ρ 1 path " There is always a way 4? No light. In this way, it is possible to achieve the AC-driven luminescence--the luminescence of the illuminating diodes on the two 1, ρ 2 , so the number of the illuminating diodes is ΐ. Similarly, the power supply on the path of ρι and p2 is appropriately designed to make it possible to use a power supply of a few volts directly using no volts, as long as the doubling light-emitting diode is realized by the present invention. I, a plurality of light-emitting diodes are easily pressed as the original: the power source is driven, and there is no need to pass the pressure-reducing effect of the transformer, so the material cost of the insulting and crying is reduced, and the soil material can be improved. brightness. In addition, the presence of a protective & plate such as zinc oxide protects the light-emitting diode in the AC-driven structure of the light-emitting diode from static electricity. Finally, the present invention has been described in detail above with respect to the specific embodiments, but those skilled in the art can change or indirectly change the invention without departing from the spirit and scope of the invention. The number of the parallel-connected light-emitting diode groups may be arbitrary, but is still the same as the same; any reverse-parallel connection of the same-direction light-emitting diode group belongs to the embodiment of the present invention. The scope of the invention is defined by the scope of the invention as set forth below.
