Problems solved by technology

[0004] However, since the rectifier components in this bridge-type AC light-emitting diode structure directly use AC light-emitting microcrystals, there will be two major disadvantages. The force is not good, so the number of rectification components used cannot be reduced, that is, it must be connected in series on the arm of the Wheatstone bridge through multiple alternating current luminous microcrystals to withstand the reverse bias applied by the alternating current. For 110V, the peak reverse bias voltage applied by the AC signal is about Therefore, a total of about 20 AC luminescent microcrystals are needed in the path of the positive or negative half-wave of the AC signal to bear the reverse bias on average and avoid the risk of breakdown by the reverse bias. Therefore, the total number of rectifier components needs to be about 20 × 2 = 40 pieces (the alternating current luminescent microcrystals in the path of the positive and negative half waves of the alternating current signal), and the number of alternating current luminescent microcrystals used to emit light is suppressed to 110V / 3.1V (each alternating current luminescence The actuating voltage of the microcrystalline grain)-20 (the quantity of the alternating current light-emitting microcrystalline grains used for rectification)=15, thus it can be seen that the quantity of the alternating current light-emitting microcrystalline grains used for rectification is far greater than the alternating current used for lighting. The number of luminous microcrystals, and since the rectification and light-emitting components (AC luminescent microcrystals) consume the same energy, the proportion of input power wasted in the rectification component remains high, resulting in poor overall efficiency. Second, although the light-emitting area has increased compared with the design of the early AC diodes, there are still a large number of rectifier components that do not emit light when they are reverse-biased, resulting in a waste of the overall light-emitting area.
