What is LED Point Light?

LED point lights are a novel type of decorative light and a supplement to linear light sources and floodlighting. By mixing colors at the pixel level, these intelligent lights can achieve area-wide effects and can replace display screens of certain specifications. An LED point light source is conceptually considered a point-like light source. The point light source is an abstract physical concept, simplified for the study of physical problems, akin to commonly referred discussions of smooth planes, point masses, and the absence of air resistance, referring to a light source that emits light uniformly into the surrounding space from a single point.

LED stands for light-emitting diode, and its working principle and some electrical characteristics are the same as those of conventional semiconductor diodes. However, different crystalline materials are used LEDs come in various types, including visible, invisible, and laser, with the most common being visible light LEDs. The color of light emitted by the diode is determined by the material used; currently, there are yellow, green, red, orange, blue, purple, cyan-blue, white, full-color, and other varieties. LEDs can also be shaped into rectangles, circles, and other forms. With advantages such as long life, small size, lightweight, low power consumption (energy efficient), and low cost, along with other attributes like low working voltage, high light efficiency, extremely short response time, wide operating temperature range, pure light color, sturdy structure (impact-resistant, vibration-resistant), and stable and reliable performance, LEDs are highly favored.

What is an LED point light source?

The LED emitter approximates a "point" light source, which makes luminaire design straightforward. However, when used for large display areas, they consume considerable current and power. LEDs are commonly used in electronic devices as indicator lights, digital tubes, display panels, and photo-couplers, as well as for optical communication. Additionally LED point lights are used for decorative purposes at locations such as building outlines, amusement parks, billboards, streets, stages, and more.

An LED point light source, utilizing a single LED as the light emitter and controlled by a freeform side-emitting lens, achieves low power consumption, high range, low maintenance, and extended life span. It meets the relevant technical standards as proven by technical testing. The use of a freeform side-emitting lens matched to the LED point source is a significant technological innovation in the new type of optical system for navigation lights.

Compared to traditional light sources, LED point lights are smaller and lighter, which allows them to be fashioned into a variety of shapes for easy arrangement and design in different luminaires and apparatuses, with strong adaptability and a broad range of applications. LED point lights are environmentally friendly; they do not require metallic mercury during production, thus avoiding mercury pollution after disposal. Almost all of their waste material can be recycled, conserving resources while protecting the environment. LEDs are safe and stable as they operate on low voltage DC power, generally between 6-24V, making them particularly suitable for public places. Additionally, LEDs have less luminous decay and a longer lifespan compared to traditional light sources, even with frequent switching, which doesn’t affect their service life.
