Abstract
A light string is composed of multiple light emitting units. Each light emitting unit utilizes multiple LEDs as the light emitting source to generate various light colors for enriching visual effects. Further, the light string is able to adhere to form any particular configuration as an attractive advertising device. By using the LEDs as the light source, power consumed by the light string is very low and operators of the light string are not exposed to high voltages.
Claims13
A light string comprising:
- multiple light emitting units sequentially connected to form the light string, wherein each light emitting unit comprises:
- a base that is composed of a bottom plate and a wall portion upwardly formed around a circumference of the bottom plate, whereby a hollow is defined by the bottom plate and the wall portion;
- a circuit board received in the hollow of the base, wherein at least one light emitting diode is installed on the circuit board as a light emitting source;
- and
- a cover plate mounted on the base, wherein the cover plate is defined with at least one opening corresponding to the at least one light emitting diode on the circuit board, thus the light generating by the light emitting diode is able to pass through the at least one opening.
