Abstract

A method of making an LED lamp circuit achieves uniform heating and cooling of an LED lamp to extend its lifetime. Steps include: providing a circuit board for an LED lamp and dispersing a plurality of light emitting diodes across a surface of the circuit board; distributing an LED driver on a surface of the circuit board so that the light-emitting-diode driver is not a distinctly identifiable component, does not interfere with the light output of the LEDs, and enables the LED driver to uniformly heat the LEDs when powering the LEDs; configuring the LED driver to attach to a power input; and integrating a heat sink to a surface of the circuit board, the heat sink configured to uniformly remove heat from the LEDs and the LED driver. The invention includes an LED lamp circuit made according to the method.

Dependent claims

A method of making a light-emitting-diode-lamp circuit comprising the steps of:

providing a circuit board for a light emitting diode lamp, the circuit board comprising a top surface and a bottom surface, each comprising a surface of the circuit board;
dispersing a plurality of light emitting diodes across a surface of the circuit board;
distributing a light-emitting-diode driver on the a surface of the circuit board, the light-emitting-diode driver configured:
so that the light-emitting-diode driver is not a distinctly identifiable component;
does not interfere with the light output of the light emitting diodes;
and,
to enable the light-emitting-diode driver to uniformly heat the light emitting diodes when powering the light emitting diodes;
configuring the light-emitting-diode driver to attach to a power input to supply power to the light emitting diodes;
and,
integrating a heat sink to a surface of the circuit board, the heat sink configured to uniformly remove heat from the light emitting diodes and the light-emitting-diode driver when the light emitting diodes are powered by the light-emitting-diode driver.
