LED point light sources are miniature point-shaped decorative lamps centered on light-emitting diodes. They are widely used in building lighting and landscape illumination. They adopt solid-state lighting technology, with low power consumption (each 0.3 - 2W), long lifespan (over 50,000 hours), environmental friendliness, and high light efficiency. Through DMX512 protocol or serial control, each point can be independently dimmed and colored, achieving dynamic effects such as flowing, gradient, and graphics. The shell is usually made of PC or aluminum alloy, with a protection level above IP65, and has strong weather resistance. They are mainly applied to building outlines, bridge guardrails, advertising signs, and stage backgrounds. When combined into a point array screen, they can replace some display screens. Combined with an intelligent control system, they can be connected to the Internet of Things for remote control, meeting the needs of smart cities.
