Embodiment Construction

[0016] The circuit of the embodiment of the present invention is as figure 1 As shown, it includes power terminal 1 connected to the AC power grid, LED component combination 2, AC capacitor 3, AC core coil 4 and single-phase bridge rectifier 5, AC capacitor 3 and AC core coil 4, single-phase bridge rectifier The AC input terminal of 5 is connected in series to terminal 1, and the LED element combination 2 is connected to the DC output terminal of single-phase bridge rectifier 5. The DC output terminal of the single-phase bridge rectifier 5 is also connected in parallel with a filter capacitor 6 of appropriate capacity. When the requirements for the double power frequency flicker of the light are not high, the filter capacitor may not be used.

[0017] The embodiment of the present invention is designed as follows: rated input voltage 220V, input power 13W; each component is designed as follows:

[0018] ——LED component combination 2 consists of 12 LED components with a rated...

Abstract

An LED lighting circuit, comprising a single-phase AC power supply and a combination of LED components; characterized in that it also includes an AC capacitor, an AC iron core coil, and a single-phase bridge rectifier circuit; the AC capacitor, AC iron core coil, single-phase The AC input end of the bridge rectifier circuit is connected in series to the single-phase AC power supply, and the LED element combination is connected to the DC output end of the single-phase bridge rectifier circuit; the capacitive reactance of the AC capacitor is greater than that of the AC iron core coil Inductive reactance, the iron core of the AC iron core coil works in the section where the magnetic permeability of the magnetic material decreases with the increase of the magnetic field intensity. The design can effectively suppress the fluctuation of the current with the power supply voltage, and the structure is greatly simplified compared with the prior art, thereby significantly reducing the cost and improving the reliability.
