Patent number 8556462 is assigned to
The following quote was obtained by the news editors from the background information supplied by the inventors: "The present invention relates to a lighting device, and more particularly to an LED lighting device with a wide angle illumination.
"Since power consumption of lighting emitting diode (LED) is relatively low, more and more LED-based lighting device are available in the market and substitute conventional illuminating elements. With reference to FIG. 10, 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.
"To overcome the shortcomings, the present invention provides an LED lighting device to mitigate or obviate the aforementioned problems."
In addition to the background information obtained for this patent, VerticalNews journalists also obtained the inventor's summary information for this patent: "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.
"Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings."
