Abstract

The invention relates to an alternating-current direct-drive LED. The LED comprises plastic packaging bodies, a high-voltage driving chip, an LED lamp bead, two metal supports and two pins, wherein the two metal supports are respectively arranged in the plastic packaging bodies, the two pins are respectively inserted in the plastic packaging bodies, each metal support is arranged at one end of one pin, the high-voltage driving chip and the LED lamp bead are respectively arranged on the same metal support, and the high-voltage driving chip is respectively and electrically connected with the LED lamp bead and the two metal supports. According to the alternating-current direct-drive LED, by designing the integrated high-voltage driving chip, a common low-light-level LED lamp is changed intohigh-voltage alternating current which can directly drive the LED lamp, electronic products applied to many low-light-level fields are directly compatible and simplified, and social benefits are obvious; when the LED lamp is driven by an alternating current, positive and negative electrodes do not need to be distinguished, and connection is convenient.

Description

technical field [0001] The invention relates to the technical field of light emitting diodes, in particular to an AC direct drive LED light emitting diode. Background technique [0002] In many areas that require low light, such as family night lights, low-light auxiliary lighting in corridors, low-light indicators in corridors, power indicators for various household appliances, power indicators for wall sockets, and power indicator lights for power strips, etc. Because the forward voltage value (VF value) of ordinary low-light LED (light-emitting diode) lamps is very low, it is necessary to convert the alternating current into low-voltage direct current to drive and light the LED lamp. Therefore, the low-light LED lights on the market are all driven by low-voltage DC. [0003] In our daily life, the daily electricity consumption is 110V AC (Europe and America) and 220V AC (China). At present, the processing methods on the market are roughly divided into three categories: ...
