LIGHT-EMITTING DIODE LIGHTING DEVICE FOR BEING DIRECTLY ELECTRICALLY CONNECTED TO ALTERNATING CURRENT POWER SUPPLY

摘要

A light-emitting diode (LED) lighting device for being directly electrically connected to an alternating current power supply includes a substrate, a first LED, a first fluorescent layer, a second LED, a second fluorescent layer, and a control module. Top surface of the substrate includes a first region, a second region, and a third region. The first LED is disposed on the first region. The first fluorescent layer covers the first LED. The second LED is disposed on the second region. The second fluorescent layer covers the second LED. The control module is disposed on the third region and electrically connected to an external power supply, the first LED, and the second LED. The bridge rectifying unit of the control module transforms external alternating current into direct current. The current-limiting unit of the control module controls whether the first LED and the second LED are turned on.
