Abstract (en)
An LED lighting device has a cap (10), a circuit board assembly (20) and a bulb envelope (30). The circuit board assembly (20) is electrically mounted on the cap (10) and has multiple circuit boards (21,22) intersecting each other to form a light frame with a crisscross section, and has multiple LEDs (23) mounted on the circuit boards. The circuit board assembly (20) may further have a top circuit board (26) mounted on one end of the light frame. The top circuit board (26) also has multiple LEDs (23a) mounted thereon. Since the circuit boards intersect each other to constitute the light frame, the light frame provides a large surface area for mounting a large number of LEDs. Therefore, the LED lighting device is able to provide a wide angle illumination with enhanced lighting intensity.
