Abstract: A lamp includes a lamp base, a lamp cover fixedly connected to the lamp base, and a light source module electrically connected to the lamp base and housed in a space enclosed by the cover and the lamp base. The light source module includes a second plate electrically connected to the lamp base, a first plate connected to the second plate, a dot matrix light source disposed on a first surface of the first plate, and an optical cover covered on the first surface of the first plate. As the dot matrix light source is capable of displaying different preset patterns, the lamp of the invention can provide bright illumination while displaying a dynamic preset pattern according to the practical needs so that images of real objects to be simulated can be vividly presented, creating the certain specific atmosphere.

Abstract: An inflatable decorative system includes an inflatable hollow bag body provided with an inflation port and a line hole, a plurality of first fixing portions having perforations or hook portions and arranged on an inner wall of the bag body, and a light string system. At least an end portion extends out of the bag body from the line hole, and the remaining portions are arranged inside the bag body and fixed among the plurality of first fixing portions so that the light string system is unfolded into a preset shape in the bag body after the bag body is inflated. The light string system can be directly hung among the plurality of fixing portions, and can also be fixed among the plurality of fixing portions by a reinforcing strip or reinforcing line.

Abstract: A light string includes at least two conductor wires each covered with an insulating coating defining plural holes acting as electrical bare spots, a controller with an input terminal connected to an external power supply and an output terminal electrically connected to the at least two conductor wires, and plural light sources. Each light source includes one or more LEDs and a circuit board having a first surface used for fixing the one or more LEDs and a second surface defining at least two conductive strips across the second surface. The at least two conductive strips are electrically connected to the at least two conductor wires through the electrical bare spots, respectively. Each connecting part between the conductive strips and the conductor wires is wrapped around by a light transmissive glue. Two conductive ends of each LED are electrically connected to two of the at least two conductive strips.
