Abstract
A lighting system comprising at least one bulb assembly, an integrated switching power supply, a plurality of electrical wires electrically connecting the bulb assembly to the power supply, and male/female connectors. The bulb assembly has a housing including a light source disposed on a surface of a printed circuit board (PCB), at least one processor provided on the PCB, at least one electrical connector disposed on another surface of the PCB and configured to connect to the plurality of wires, and a means for sealing the housing against water ingress.
Claims20
A bulb assembly for a holiday lighting system comprising:
- a housing;
- a plurality of electrical wires that are substantially shaped to conform to the housing when assembled;
- a printed circuit board (PCB) having a first surface and a second surface opposite the first surface, the PCB further comprising:
- a plurality of insulation displacement connectors (IDC) or solder pads, disposed on the first surface of the PCB;
- a light source is a light emitting diode (LED) and is disposed on the second surface of the PCB;
- and
- a processor disposed on the PCB and configured to:
- receive serial data signal to control the light source brightness levels;
- and
- use 3 or 4 bytes data to determine the LED brightness levels;
- wherein the plurality of electrical wires electrically connects to the IDCs or solder pads;
- wherein the PCB, processor, light source and wire connections form a circuit sealed from water ingress by either a potting compound, conformal coating, or by a water-tight seal lid.
(canceled)
A lighting string system for a permanently installed holiday lights comprising:
- a male connector;
- a female connector;
- a plurality of electrical wires;
- a switching regulator built into the lighting string system;
- and
- one or more bulb assemblies, each bulb assembly further comprising:
- a housing;
- a printed circuit board (PCB) having a first surface and a second surface opposite the first surface, the PCB further comprising:
- a plurality of insulation displacement connectors (IDC) or solder pads or at least one electrical connector, disposed on the first surface of the PCB;
- a light source disposed on the second surface of the PCB;
- and
- at least one processor disposed on the PCB and configured to:
- receive a serial data signal to control light source brightness levels;
- and
- process 3-4 bytes of data;
- wherein the plurality of electrical wires:
- comprises a data wire and the data wire is configured to have a break in the circuit;
- electrically connect to either the IDCs, solder pads or the at least one electrical connector;
- is placed between the male connector and female connector;
- and
- connects the plurality of bulb assemblies and the regulator to form a circuit;
- wherein the PCB, processor, light source and wire connections form a circuit sealed from water ingress.
