Abstract
An LED lighting device has a cap, a circuit board assembly and a bulb envelope. The circuit board assembly is electrically mounted on the cap and has multiple circuit boards intersecting to each other to form a light frame with a crisscross section, and has multiple LEDs mounted on the circuit boards. The circuit board assembly may further have a top circuit board mounted on one end of the light frame. The top circuit board also has multiple LEDs mounted thereon. Sine the circuit boards intersect to each other to constitute the light frame, the light frame provides a large surface area for mounting a lot number of LEDs. Therefore, the LED lighting device is able to provide a wide angle illumination with enhanced lighting intensity.
Claims19
An LED lighting device comprising:
- a cap having a top opening and an inner space communicating with the top opening;
- an insulative base mounted in the inner space and protruding upward from the top opening of the cap;
- a circuit board assembly mounted on a top of the insulative base and having
- multiple rectangular circuit boards intersecting each other to form a light frame with a crisscross section, wherein the light frame is mounted on the insulative base and above the top opening of the cap;
- and
- multiple LEDs mounted on two opposite surfaces near a longitudinal edge of each circuit board and emitting light toward different directions;
- a top circuit board mounted on a top of the light frame opposite to the insulative base and electrically connecting to the circuit boards, and multiple LEDs mounted on the top circuit board;
- a bulb envelope securely mounted on the cap and enclosing the circuit board assembly and the base.
