Patent number: 8314564Abstract: A capacitive full-wave circuit for LED light strings makes use of capacitors and diodes together to drive a LED string with full AC waves. Different from the conventional four-diode full-wave rectifying circuit, one embodiment of capacitive full-wave circuit includes two capacitors and two diodes. Because of the large imaginary impedance, the capacitors not only limit and the voltage and current through the LEDs, but also consume almost no electrical power. The electrical current-voltage performance can be further improved by introducing four resistors with a cost of some additional power consumption. A LED light string module with the capacitive full-wave circuit is also presented, with the capacitive full-wave circuit integrated inside of a front power plug and a back power socket.Type: GrantFiled: April 28, 2009Date of Patent: November 20, 2012Assignee: 1 Energy Solutions, Inc.Inventors: Jing Jing Yu, Lianfeng Ma

Patent number: 8016440Abstract: Disclosed are circuits that allow LED bulbs to be replaced regardless of color or construction of the LED element. When used for an LED light string, replacing an LED bulb does not affect the operation of the entire string. When used for other illumination purpose, for example, room light, the bulbs are interchangeable because they have the same operating voltage and current. A standardized input impedance is selected for all of the LED bulbs regardless of construction and color. A resistor circuit is used to create the standardized input impedance while optimizing the operating parameters of the LED element. The resistor circuit includes a bypass element so that if a LED element burns open, a series wired LED string will not go dark. This eliminates the necessity for parallel connected LED bulbs and allows enjoyment of other advantages and economies of series wired LED strings.Type: GrantFiled: April 5, 2008Date of Patent: September 13, 2011Assignee: 1 Energy Solutions, Inc.Inventors: Jing Jing Yu, Shengwang Du

Patent number: 7963670Abstract: Disclosed is an LED light string that uses parallel connected bypass components that are connected across the leads of the LEDs and are disposed in the socket of the LED lamp holder. The use of parallel connected bypass components across the leads of the LEDs greatly enhances the reliability of the light string. Bypass components are also included in the LED lamp structure, both internally to the LED lamp proxy and externally across the leads of the LED lamp element. A resistive wire can also be connected between conductors in an LED socket structure inside a lamp holder. Using the bypass components, twinkle lamps can be inserted in series wired LED light strings.Type: GrantFiled: July 31, 2007Date of Patent: June 21, 2011Assignee: 1 Energy Solutions, Inc.Inventor: Jingjing Yu

Patent number: 7883261Abstract: Disclosed is waterproof lamp assembly that allows easy assembly and disassembly. LED elements can be quickly and easily replaced if an LED element is defective or burns out. Extended connectors are used that extend beyond an overmolded lamp holder so that the lamp holder can be easily molded without covering the connectors with molding material. The connectors are made from a malleable metal so that the connectors can be folded into a central opening in the lamp holder.Type: GrantFiled: October 20, 2008Date of Patent: February 8, 2011Assignee: 1 Energy Solutions, Inc.Inventor: Jing Jing Yu
