Description

A string of lights Technical Field

The utility model relates to the technical field of lamps, and in particular to a string of lamps.

Background Art

String lights are widely used for indoor and outdoor decoration. They are common decorations for festivals and night scene beautification. String lights mainly refer to lighting fixtures connected in series in an electrical circuit. They generally have multiple lamp bodies connected by wires, so that the string lights can surround the decorated objects and enhance the visual effect of the decorated objects at night.

The light source of existing string lights generally uses red, green and blue LED lamp beads to adjust different colors of visible light according to the principle of optical three primary colors. Since each primary color LED lamp bead can only emit a single color of light, and the light output area of the lamp body is small, if the number of each primary color LED lamp bead in the lamp body is too small, the emitted light is easily affected by the installation position of the LED lamp bead, resulting in uneven light output and color cast. In order to ensure that the light emitted by the lamp body is uniform and the color is accurate, the existing method is to set multiple LED lamp beads of each primary color and arrange them in a certain order in the lamp body, which increases the volume of the lamp body and increases the manufacturing cost.
