An LED lighting device includes a power supplier, a light cover and a circuit board. The circuit board is disposed in the light cover. The circuit board has a protective layer disposed thereon and a plurality of light sources. The circuit board has a front soldering section, a rear soldering section and a circuit section. The light sources are disposed on the circuit section and electrically connected to the circuit section. The protective layer includes an opening and two coated layers. The opening includes a front section, a rear section and a connecting section. The coated layers are disposed on the two sides of the connecting section respectively. The light sources are within the connecting section. The inner space of the light cover serves as an optical zone, such that the optical zone covers the front soldering section and the rear soldering section.

LED lighting device

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.

A lighting device includes an end cap, a circuit board, a plurality of first and second connection pins and a tubular housing. The end cap includes a hollow cylindrical portion and a connection portion. The hollow cylindrical portion has an opening and an installation bottom surface, and an accommodating space is formed therebetween. The connection portion includes a plurality of first and second hollow connection tubes connected to the accommodating space. The circuit board is disposed on the installation bottom surface, and includes a plurality of first connection points and a plurality of second connection points. The first connection pins penetrate through the first hollow connection tubes respectively in order to connect to the first connection points. The second connection pins penetrate through the second hollow connection tubes respectively in order to connect to the second connection points. The tubular housing is connected to the end cap.
