Definitions

  • the present invention relates to a lighting device, and more particularly to an LED lighting device with a wide angle illumination.
  • a conventional LED lamp mainly comprises a circular circuit board 50 with multiple LEDs 51 mounted thereon to emit light.
  • the light generated by the LEDs 51 is directional. If the LEDs 51 are mounted on the same plane, the light from the LEDs 51 will irradiate toward the same direction. Therefore, the conventional LED lamp is unable to provide a wide angle illumination area.
  • the present invention provides an LED lighting device to mitigate or obviate the aforementioned problems.
  • the main objective of the invention is to provide an LED lighting device with a larger area for mounting multiple LEDs that emit light toward different directions to achieve a wide angle illumination.
  • An LED lighting device in accordance with the present invention comprises 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, the light frame has a large surface area for mounting a lot number of LEDs. Therefore, the LED lighting device providers a wide angle illumination area with enhanced lighting intensity.
  • a first embodiment of an LED lighting device of the present invention comprises a cap 10, a circuit board assembly 20 and a bulb envelope 30.
  • the cap 10 has an inner space to hold a base 11.
  • the cap 10 is made of conductive material and may have a screwed outer surface to electrically connect to a socket.
  • the base 11 is an insulative base, for example a glass base.
  • the circuit board assembly 20 is mounted on the base 11 and electrically connected to the cap 10.
  • the circuit board assembly 20 has different embodiments in the present invention and preferably comprises multiple circuit boards 21, 22 and multiple LEDs 23.
  • the circuit boards 21, 22 intersect each other to form a light frame with a crisscross section.
  • Each of the circuit boards 21, 22 may have a slot 210, 220 so that the circuit boards 21,22 intersect each other by the slots 210, 220 to form the light frame.
  • the circuit boards 21, 22 may be aluminum printed circuit boards (PCB) with high heat dissipation ability.
  • the LEDs 23 are mounted on two opposite surfaces of each circuit board 21, 22. Preferably, the LEDs 23 are arranged in a straight line near the longitudinal edge of each circuit board 21, 22.
  • the circuit board assembly 20 may further comprise terminals or wires 25 that extend through the base 11 and electrically connect to the cap 10 for conducting power.
  • the bulb envelope 30 is securely mounted around the cap 30 and not limited to a particular shape.
  • the shape of the bulb envelope 30 may be a candle fire as shown in Fig. 1 or a ball as shown in Fig. 4 .
  • the circuit board assembly 20 can further comprise a top circuit board 26 mounted on one end of the light frame opposite to the base 11.
  • the top circuit board 26 is electrically connected to the circuit boards 21, 22 and has multiple LEDs 23a mounted thereon to increase illuminating area and enhance the lighting effect.
  • the top circuit board 26 can be, but not limited to, crisscross, circular, rectangular as shown in Figs. 6 to 8 .
  • one end of the light frame may have a protrusion 211 and the top circuit board 26 have a through hole 260 mounted around the protrusion 211 correspondingly.
  • the protrusion 211 may be formed on the top edge of one of the circuit boards 21, 22.
  • the circuit board assembly 20 may further comprise multiple top LEDs 23b perpendicularly mounted near a top edge of each circuit board 21, 22 opposite to the base 11. Therefore, the top LEDs 23b near the top edge project in one direction opposite to the base 11 and different from the directions of light emitted by the LEDs 23 mounted near the longitudinal edge. Since the lights emitted by the top LEDs 23b near the top edge and generated by the LEDs 23 near the longitudinal edge are orthogonal, this arrangement allows the LED lighting device to generate a wider illumination area.
  • the circuit boards 21, 22 of the circuit board assembly 20 are arranged to form a three-dimensional light frame with a surface large enough for mounting a lot number of LEDs to enhance intensity of illuminating light and provides a wide angle illumination.
  • the generated heat can be dissipated efficiently.
