Abstract
A universal platform may be used to create a family of LED light bulbs with lower costs. One universal platform includes a lamp base, a lamp holder, and a driver. Different upper bulb portions may be assembled on this universal platform. An alternate universal platform include a lamp base, a lamp holder, a heat sink, a driver shell, a driver, a PCB, and one or more LEDs. Different diffusers may be connected to this platform to produce different bulb designs. The bulbs may include an optional diffuser for producing omnidirectional light.
Claims18
A system for an LED light bulb using convection cooling to lower an operating temperature of components of the bulb, the system comprising:
- a heat sink comprising an first ring and a second ring, the first ring comprising a larger diameter than the second ring, the heat sink further comprising a plurality of fins connecting the first ring to the second ring;
- a lamp holder disposed around the heat sink, the lamp holder comprising a top opening and a plurality of vents, the top opening and the vents defining an airflow path, the airflow path passing over a fin of the heat sink;
- a driver shell disposed within the heat sink;
- a driver disposed within the driver shell;
- a print circuit board (PCB) comprising a surface, the PCB connected to the driver and to the heat sink, the PCB configured to receive electrical power from the driver, the PCB further configured to transfer heat to the heat seat;
- and
- a light-emitting diode (LED) disposed on the surface of the PCB and configured to illuminate when the PCB is receiving electrical power from the driver.
A method for assembling a universal platform for assembling a family of LED light bulb designs, the universal platform providing at least lower manufacturing costs, the method comprising:
- providing a lamp base configured to removably attach to a standard lamp socket;
- connecting a lamp holder to the lamp base, the lamp holder configured to connect to a plurality of upper bulb portions;
- placing a driver within the lamp holder and connecting the driver to the lamp base, resulting in a universal platform for assembling a family of LED light bulb designs.
A method for assembling a universal platform for a family of LED light bulb designs, the universal platform providing at least lower manufacturing costs, the method comprising:
- providing a lamp base configured to removably attach to a standard light bulb socket;
- connecting a lamp holder to the lamp base, the lamp holder comprising a plurality of vents;
- placing a heat sink within the lamp holder, the heat sink comprising a first ring and a second ring, the first ring comprising a larger diameter than the second ring, the heat sink further comprising a plurality of fins connecting the first ring to the second ring;
- placing a diver shell within the heat sink;
- placing a driver within the driver shell, the driver connected to the lamp base;
- and
- connecting a printed circuit board (PCB) to the first ring of the heat sink, the PCB having a surface, an LED disposed on the surface,
- wherein at least one of the heat sink and the lamp holder is configured to receive a diffuser, resulting in a universal platform for assembling an LED light bulb.
