Abstract: The present invention relates to a Christmas bulb structure, which is provided with a pair of conducting wire in the bulb and one filament and two or more fuses connecting with the two conducting wires in parallel. It increases the well rate of the assembled light string and prevents the bulb from broken caused of the filament being burned out. And also it lengthens the used period of the bulb and the light string.

Abstract: The invention relates to a connecting structure of a light bulb holder, which is provided with an easy connecting design at the outside walls of the body for effective connecting with electric wires securely. The invention is particularly used in a net-type or a curtain-type decorative light string. By use of enough connecting strength, the bulb holders are able to connect with the wires in order that the complete decorative configuration can be obtained and remained perfectly.

Abstract: An electrical connection mechanism used in a miniature light bulb string mainly comprises a block or plug that can be inserted into the lower portion of a bulb holder shell. The block or plug is provided with a U-shaped conductor plate that presses against two opposite conductive terminals when it is seated in the shell to form an electrical connection between the terminals. Thus when one of the light bulbs is in malfunction, electrical current in the miniature light bulb string still can be maintained.

Abstract: An engaging mechanism used in miniature light bulb sockets is provided that comprises a pair of outwardly projecting claws disposed on one side of a bulb holder and a raised block formed on the side wall of a light bulb socket body on a corresponding position. These two claws define a slot therebetween. Each claw has a stepped face on its inner surface. The raised block is configured to have an outwardly extending outer end that has a larger thickness with a round top. When the light bulb holder is mounted on the top of the socket body, the raised block extends into the slot between two claws and can be securely held therein.

Abstract: The disclosed in this invention is a hanger used for decorative light bulb strings. It primarily consists of a loop portion and a resilient retainer portion. A decorative light bulb string can be hung with ease by routing the electrical conductive wires thereof through the retainer portion of a hanger to form an arcuate light bulb array and further attached to other supporters by the loop portion of a hanger to display a unique decorative effect. In addition the hanger structure is also cost effective in manufacturing and thus it has economic value in industry.

Abstract: A connecting assembly for a decorative lighting net employing intercrossed electrical wires to connect a plurality of bulb units is provided. The connecting assembly includes a bulb holder having at least one L-shaped beam formed at a side thereof. The connecting assembly also includes a bulb connector coupled to the bulb holder having at least one L-shaped beam oriented in a direction opposing the direction in which the bulb holder's beam is oriented. The bulb connector's beam engages the bulb holder's beam in longitudinally offset manner to block the escape of electrical wire retained within the bulb holder's beam.

Abstract: A connection assembly for a decorative lighting net employing intercrossed electrical wires to connect a plurality of bulb units (for complete net or curtain-type decorative effect, for instance) is provided. The connection assembly includes a bulb holder having an arched hook formed at a side thereof. The connection assembly also includes a bulb connector coupled to the bulb holder having a stick formed at a side thereof. The stick blocks wires retained within the arched hook from escape.

Abstract: A connecting structure type (III) of a decorative lighting net includes several electrical wires intercrossed and connected with a plurality of bulb units to become a complete net or a curtain-type decoration. A receiver having an inner circular groove is formed at a side of the bulb holder and an L-shape beam is formed at a side of the bulb connector. After assembly of the bulb holder, the wires, and the bulb connector, the receiver and the L-shape beam will fix the wires with the bulb unit securely and that obtains a perfect connection between the wire and the bulb unit.

Abstract: The invention relates to a retainer mechanism used for holding a net-type array of miniature light bulbs. The retainer mechanism includes a C-shaped loop adaptable for coupling with a miniature light bulb socket. The C-shaped loop is provided with a symmetrical hook portion on two sides of the C-shaped loop. The hook portion has a bulged outer end that, in cooperation with the inner end, forms an entirely embracing structure around electrical wires that pass through the hook portion. Thus the retainer mechanism according to the invention can effectively seize electrical wires. Furthermore, the retainer can be individually made and so it is applicable to current miniature light bulb sockets without any changes on the socket structure.

Abstract: An improved insulated structure of a light bulb assembly, includes a bulb engaged within a bulb holder received in a housing. An improved connecting beam with two lower steps is formed on the holder to be received in an inner hole having a similar configuration of the housing. After connecting the bulb holder and the housing, the light bulb assembly can provides a perfect sealed connection for insulating infiltrating water or moisture to prevent an electrical short circuit and damage.

Abstract: A structure is provided which is used for a rectangularly arrayed miniature light bulb series. The structure includes a first controller (3) which regulates and controls the current in a first light bulb string (1). A second controller (4) regulates and controls the current in a second light bulb string (2). The first and second light bulb strings (1) and (2) are joined in series by a first connecting conductive wire (5) and the second controller is in electrical communication with the first light bulb string (1) through a second connecting conductive wire (6). In this manner, light bulbs in light strings (1) and (2) may be coordinated with each other.

Abstract: A curtain type decorative light string set capable of connecting with several independent light strings is provided. The light strings are connected in parallel and use the main electrical wires as a support, to be hung on other objects to prevent the light strings from loosening and thereby ensure that all other bulbs stay lit.

Abstract: The present invention relates to an improved light bulb holder for a decorative light string net which has a pair of connecting base mounted on its two sides having related outward grooves for engaging with the electrical wires more convenient and easy to form a beautiful decorative light string net.

Abstract: The present invention relates to an improved light bulb socket structure for use in a decorative light bulb series which is provided with a rod on the bottom of the light bulb holder to embrace the electrical wires with the walls of the light bulb socket and to close the opening on the bottom of the socket body in a watertight manner. The inventive socket structure can prevent water or moisture from penetrating into the interior of the socket body and deteriorating the conductor parts of the socket.

Abstract: A light bulb holder having draining passageways includes a base connecting with a cap having engaged with a light bulb wherein two channels are formed on the sides of the cap and two grooves are provided in related inner sides of the base. After a connection between the cap and the base, two channels and two grooves become two draining passageways through the light bulb holder that provides infiltrating water pass by very soon and prevent from an electrical short circuit or eroding.

Abstract: A connector for a decorative light set comprises first and second clamping members which are fixedly attached to each other and have substantially semi-circular bodies which define linearly opposed first and second openings that releasably and grippingly receive a frame member of a decorative sign and a base of a light bulb, respectively.
