Description

  The present invention relates to a package structure of a light emitting diode having a rectifier circuit, and in particular, a rectifier circuit can output an AC power source of a general supply power in a DC form, causing the light emitting diode to emit light and directly connecting to general household electricity. The present invention relates to a light emitting diode package structure provided with a rectifier circuit that can be connected and used and does not require a separate rectifier device.

  In general, when a light emitting diode is used for lighting with an AC power supply, a known light emitting diode requires only a voltage of 2 to 4 V, and the AC power supply is 110 V. Otherwise, a known light emitting diode cannot be used. A general light emitting diode is rectified and stepped down is installed outside the light emitting diode.

  As shown in FIG. 8, a conventionally known light emitting diode has a large number of light emitting diodes 90 mounted on a circuit board 91, a regulator 92 and a rectifier 93 connected to the circuit board 91, and an AC power supply is connected to a DC power supply. The light is output in a form, and the light emitting diodes 90 are made to emit light through a regulator 92 and a rectifier 93. The lighting device 9 can be formed by providing a large number of light emitting diodes 90, a circuit board 91, a regulator 92, and a rectifying device 93 in a casing 94. (A circuit diagram is shown in FIG. 9).

The illumination device 9 can be supplied for illumination with increased brightness by a large number of light emitting diodes 90. However, since a large number of light emitting diodes 90 cannot be directly used as an AC power supply, a regulator 92 and a rectifier 93 must be additionally provided to convert AC into DC at the time of use. Therefore, normally, the volume of the lighting device 9 is large, and the current is liable to cause a circuit loss. Further, if a large number of light emitting diodes 90, the circuit board 91, the regulator 92, and the rectifying device 93 are configured as components, the cost will be increased. And the known lighting device 9 does not meet the requirements of the actual use situation.
