Abstract: A LED lamp string, especially indicating a type of LED lamp string, which plug-fitting directly into AC power socket, and a controllable blinking or non-blinking structure which combining two or more than two groups of dual crystal current controllers in the main electrical wire circuitry to achieve results of bridge rectifier to make the current flowing through the LED lamp string become the state of DC current and thus achieve the non-blinking effect.

Abstract: The invention relates to a controlling apparatus of an AC LED string, which includes a controller to control the string being capable of flickering or totally unflickering very easily. The apparatus can also connect an adjustable resistance for application on a string with various numbers of LEDs. The apparatus includes at least one set of a pair of slots with different shapes or sizes at output ends for connecting with the LED string correctively that obtains improvement and utilization.

Abstract: The present invention relates to a C-type bulb assembly, which includes a bulb holder connecting with a bulb and a connector. A C-type shell is connected with the holder outside the bulb, wherein the opening fringe of the holder is formed with several slots to become several elastic pieces.

Abstract: This invention relates to a long bulb structure, which includes a long glass shell being provided with two or more sunken circular areas. The inner surface of the sunken circular area may contact two conductive wires to maintain them in a right position in the glass shell and to prevent tungsten wires connected between the conductive wires from teaching the glass shell. The glass shell is thus avoided from being heated and broken and the bulb can be used in secure.

Abstract: The present invention relates to a decorative shell of a bulb assembly of a light string. The decorative shell is provided with an inward extended connecting portion to engage with a bulb holder of a bulb assembly that keeps a complete original pattern of the decorative shell. A bulb of the bulb assembly can be inserted into inner space of the shell and near to front surface of the shell to increase lighting degree and decorative effect.
