20120326184 | LED LIGHTING FIXTURE AND THE MANUFACTURING METHOD THEREOF - A LED (Light-Emitting Diode) lighting fixture and a manufacturing method thereof are disclosed. The LED lighting fixture comprises a LED module generating light at a wavelength range of 300-700 nm, a lamp cover shielding the LED module, and a phosphor layer. The phosphor layer which is coated on an inner surface towards the LED module comprises at least two types of phosphor mixed at a default ratio for transforming the light of 300-700 nm in wavelength to luminary light in the wavelength range of 400-700 nm. | 12-27-2012 |
20120320562 | LED LIGHTING DEVICE - An LED (Light-Emitting Diode) lighting device is provided. The LED lighting device comprises an LED module, a lamp cover, and a phosphor layer. The LED module comprises a circuit board comprising a driving circuit and a plurality of LEDs mounted on the circuit board and driven by the driving circuit so as to emit light of 300-700 nm in wavelength. The lamp cover is configured to shield the LED module. The phosphor layer is coated on an inner surface of the lamp cover towards the LED module and configured to transform the light of 300-700 nm in wavelength to a luminary light of 400-700 nm in wavelength. | 12-20-2012 |
20120314426 | LED Bulb Structure - A LED (Light Emitting Diode) bulb structure includes a base, a plurality of fins and a shell. One end of the base is electrically connected to a power source, and the other end of the base is used for holding a LED light source. The fins are disposed on a surface of the base. The shell encloses the fins, and the shell includes a plurality of first heat-dissipation holes and a plurality of second heat-dissipation holes. The first heat-dissipation holes are arranged around the shell and corresponding to the fins for allowing airflow entering the first heat-dissipation holes to directly pass through each of the fins corresponding to each of the first heat-dissipation holes. The second heat-dissipation holes are arranged around the shell and disposed above the first heat-dissipation holes for enabling the first heat-dissipation holes and the second heat-dissipation holes to conduct thermal convection. | 12-13-2012 |
