Abstract

The present invention relates to an uninterruptible LED bulb string structure, comprising a resistor coupled between two pins of a LED bulb, such that the two pins are wrapped by plastic materials to integrally fix the resistor to a front end position of a cathode connection line and an anode connection line of another pins of the chip, so that when the string of the LED bulbs is under the division of voltage or current or the electrically connected parts are disconnected, the resistor will connect the two isolated pins to continuously supply power to the entire LED bulb strings and keep a normal and reliable light source for the illumination. This invention specially helps the extension of its life and is not easy to scrape for the economic benefit.

Claims

1. An uninterruptible LED bulb string assembly, comprising a resistor electrically coupled between a pair of pins of a LED bulb chip and another pair of pins to integrally fix the two pins onto a front end position of a cathode connection line and an anode connection line, such that when said LED bulb being under the situation of division of voltage and current and the connection line being deteriorated to cause a power disconnection, the resistor connected to the two isolated pins obtaining an uninterruptible power supply and keeping a normal and stable light source for illumination effects.
