Abstract:
A method is applied to manufacture a thin type light emitting diode (LED) assembly, and comprises the steps of: pressing a light-transmissible conductive film onto a carrier; etching an etched circuit on the light-transmissible conductive film to form an etched light-transmissible conductive film; bonding a LED chip on the etched light-transmissible conductive film to make the LED chip electrically connected with the etched circuit; covering the LED chip and the etched light-transmissible conductive film with a light-transmissible encapsulation layer to encapsulate the LED chip therein; and cutting the carrier to make the carrier be removed from the etched light-transmissible conductive film, so as to manufacture the thin type LED assembly.
Abstract:
A white light emitting diode comprises a light emitting diode chip for emitting a blue light, a first wavelength conversion layer and a second wavelength conversion layer. The light emitting diode chip comprises a first lighting area and a second lighting area through which at least two currents flow, respectively. The first wavelength conversion layer is coated on the first lighting area and generates a first conversion light upon excitation by the blue light. A warm white light is generated by mixing the blue light and the first conversion light. The second wavelength conversion layer is coated on the second lighting area and generates a second conversion light upon excitation by the blue light. A cold white light is generated by mixing the blue light and the second conversion light. The amount of the currents can be controlled to modify the luminescence intensity of each light area, thus adjusting the color temperature of the white LED.

A method of manufacturing a light-emitting diode package, including following steps: providing a mounting base; providing a light-emitting chip on the mounting base, and the light-emitting chip including at least one electrode on the top surface thereof; forming a fluorescent layer on the top surface of the light-emitting chip, and the fluorescent layer covering the electrode; providing a laser generator to emit a focused laser beam to remove a portion of the fluorescent layer covered on the light-emitting chip to form a through-hole; providing a conductive wire to electrically connect the electrode of the light-emitting chip via the through-hole to the mounting base. The conductive wire can then be electrically connecting the electrode to the mounting base via the through-hole. Therefore, the thickness of fluorescent layer around the metal wire would be evenly formed, resulting better uniformity of white light mixing of the light-emitting diode package.
