Decorative Light String With LED Bulbs

Conventional decorative light string has been used for a long time which includes an electrical wire connecting with a plurality of light bulbs. The known bulbs are almost filament-bulbs (1), as shown in FIG. 1. These bulbs will be very hot after being used for a period of time. Therefore, the heat of the filament-bulbs is possible to burn something around them, that might hurt a user who carelessly contacts the bulbs or cause a terrible accident of fire.

The main object of the invention is to provide an improved decorative light string with safe LED bulbs which will not occur heat and is capable of being safely used for a long time.

The detailed structure, features, and other advantages of this invention will become apparent from the following detailed description of a preferred embodiment when read with reference to the accompanying drawings.

FIG. 1 is a perspective view showing a prior art embodiment of a filament-bulb assembly of a light string.

FIG. 2 is a perspective view showing a preferred embodiment of an improved LED bulb assembly according to this invention.

Referring to FIG. 2, it can be seen that the present invention includes a base (2), a light bulb holder (3), a LED bulb (4) having a pair of leads (41), wherein the base (2) is provided with a dint (21) at one side and the light bulb holder (3) is also provided a dint (31) at one side on its top. The LED bulb (4) is received in the holder (3) with one of the leads (41) aligned with the dint (31). The holder (3) accompanying with the LED bulb (4) is then engaged within the base (2) in a direction of the dint (31) of the holder (3) matching the dint (21) of the base (2). The corrective connection between the base (2) and the light bulb holder (3) is for the use of the LED bulb (4). By aligning the dints on base and the light bulb holder, it is convenient to complete an LED bulb assembly of the present invention.

It is to be understood that the light string of this invention includes a series of wire connecting with a plurality of LED bulbs which light without high heat. Users can hang this light string on any desired place and prevent from any accident or damage. Accordingly, the structure of the present invention makes obvious improvement and should be patentable.
