Abstract: A LED flash bulb decorating light with features of able to achieve complicated light variation by employing simple circuit design, which comprises a power cord with a power plug, a series of single color, dual color or multiple color LED flash bulb forming in series or parallel circuit with the power cord. And a circuit control box comprises a low pass filter circuit and a power reset circuit and installed between the power plug of the power cord and the LED flash bulb, wherein the LED flash bulb at least comprises a LED chip and an IC driving element for driving the LED chip with DC power according to the setting time sequence to generate desired light variation. And the power reset circuit reset power supply at the repeated setting time interval to enable each LED flash bulb on the power cord to restart flash sequence to maintain the desired synchronous light variation.

Abstract: An improved LED lighting string employs a rectified and filtered device functioned as a low pass filter device to rectify input AC source into DC source providing to the LED lighting string for improving LED's flickering issue and to upgrade the optical power factor and efficiency, and luminous intensity in LED lighting string.

Abstract: A LED melody decoration kit with multicolor light sources comprises an electrical wire with a plug-connector to get a voltage from a traditional lighting string, one or more LED lights to emit single or multiple lighting colors, and a cover package having a driving IC to drive and control the LED lights, which is directly applicable to change one of the incandescent lamps from a traditional lighting string for replacement, and which do not change the function of the original lighting string to emit single color or different multiple colors and obviously create plenty of effect in lighting string.
