decorative lights

technical field

The utility model relates to a decorative lamp, in particular to a decorative lamp using a light-emitting diode as a light source.

Background technique

Generally speaking, decorative lamps use small light bulbs as light sources. However, with the progress of the times, some decorative lamps use light-emitting diodes as light sources. Because light-emitting diodes have the advantages of power saving, high stability, and no high heat generation, it makes Light-emitting diodes are becoming more and more popular as decorative lamps.

The currently known U.S. Patent No. 6,452,317 case uses light-emitting diodes as a decorative lamp. When assembling the electric wires electrically connected with the pins of the light-emitting diodes, the pins of the light-emitting diodes are passed through the lamp base, and then bent upwards, so that the pins of the light-emitting diodes are attached to the outer wall of the lamp base Afterwards, when the lamp stem is mounted on the lamp holder, the pins of the light-emitting diodes are firmly electrically connected to the wires. In the process, an additional step of bending is required, thereby increasing the production cost.
