Disclosed is a low cost LED string circuit design that uses an inexpensive half-wave rectification and low-pass filter circuit that is designed to produce minimal flicker in the LED string that is connected to the circuit. The components of the half-wave rectification and low-pass filter circuit are selected in accordance with design principles that prevent glittering and flickering of the LED string. The circuit components of the half-wave rectification and low-pass filter circuit can be embedded in an outlet plug or as a separate independent unit between an AC power plug and the LED string.

Disclosed is an integrated LED bulb that utilizes LEDs and can be used as a standard replacement bulb for incandescent lights that operate on standard household current. One or more LEDs are disposed in a lens that is capable of high optical transmission efficiencies. A base portion encapsulates a printed circuit board and connectors, as well as the LED pin leads to hold the package in a secure mounting. The lens can be molded directly to the base or can be removable. The base can be formed to fit standard threaded sockets or bayonet sockets.

Disclosed is a three-piece light emitting diode lamp. The lamp comprises a lamp holder that encapsulates and seals various connectors and connections. A removable light emitting diode is inserted into contact sockets so that the light emitting diode can be easily replaced. Various techniques are used to provide proper polarity for placement of the light emitting diode in the contact sockets. A lens cover is engaged in a ring cavity between an inner annular wall and an outer annular wall that seal and hold the lens cover to the lamp holder and provide a watertight seal.

Disclosed is an LED lamp assembly that allows an LED lamp to be removably replaced in a lamp holder. A solid, electrical connection is created between the LED pins and electrical terminals as well as connecting wires without soldering. An LED lamp is removably connected to a base that can be inserted in and removed from a socket that is attached to connecting wires. The LED lamp can be removed from the base for replacement of the LED lamp.

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.

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.

Disclosed are LED lamp assemblies that are substantially inseparable. The LED lamp assemblies use discrete components that are individually manufactured and then assembled in a manner that substantially prevents disassembly or disengagement of components. An interference fit can be used to substantially secure components of the LED lamp assemblies. Bonding techniques can also be used, including adhesive and solvent bonds, as well as thermal bonds, including sonic bonds.

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.
