LED point light sources are new type of point-shaped decorative lamps that use light-emitting diodes (LEDs) as the light-emitting components. They are a supplement to linear light sources and floodlighting. They emit light through semiconductor PN junctions and have the advantages of small size, low power consumption, and long lifespan. Through internal microcomputer chip programming control, they can independently change or form a matrix to achieve full-color dynamic effects such as seven-color, flowing water, and graphic animation. The products are mainly applied in outdoor landscape decoration lighting fields such as building outlines, bridge lighting, advertising signs, and entertainment venues.
