Abstract
A light-emitting diode (LED) lighting device includes a light cover and a circuit board. The circuit board is disposed in the light cover and has a protective layer disposed thereon. The protective layer includes an opening and two coated layers. The opening includes a front section, a rear section and a connecting section. The front section is connected to the rear section via the connecting section, and the coated layers are disposed on the two sides of the connecting section respectively. As the protective layer has only one opening, so the coating process thereof can be significantly simplified. Thus, the manufacturing cost of the LED lighting device can be greatly reduced.
