LED point light source is a new type of decorative light, which is a supplement to the linear light source and floodlighting. Smart lamps that can replace certain specifications of display screens that achieve the effect of dots and surfaces through pixel color mixing. The LED point light source is idealized as a particle point light source. Point light source is an abstracted physical concept, in order to simplify the study of physical problems. Just like a smooth plane, a mass point, and no air resistance, it refers to a light source that emits uniformly from a point to the surrounding space.

LED is a light-emitting diode. Its working principle and some electrical characteristics are the same as ordinary crystal diodes, but the crystal materials used are different. LED includes visible light, invisible light, laser, and other different types, and the common one in life is visible light LED. The light-emitting color of light-emitting diodes depends on the materials used. Currently, there are multiple colors such as yellow, green, red, orange, blue, purple, cyan, white, and full color, and can be made into various shapes such as rectangles and circles. LED has the advantages of long life, small size, and lightweight, low power consumption (energy saving), low cost, etc., and low working voltage, high luminous efficiency, extremely short luminous response time, wide operating temperature range, pure light color, and strong structure ( Shock resistance, vibration resistance), stable and reliable performance and a series of characteristics, are very popular among people.

The luminous body of D is close to the “point” light source, and the design of the lamp is more convenient. However, if it is used as a large area display, the current and power consumption are both large. LEDs are generally used for display devices such as indicator lights, digital tubes, display panels, and photoelectric coupling devices of electronic equipment, and are also commonly used for optical communications, etc., as well as the decoration of building outlines, amusement parks, billboards, streets, stages, and other places.

LED point light source, it uses a single LED as the light source, and controls the light path through the free-form surface side light-emitting lens, which achieves low power consumption, high range, low maintenance, and long life. After technical testing, it meets the requirements of relevant technical standards. A new type of beacon light optical system matching the free-form side light-emitting lens and the point light source LED is an important technological innovation realized by the light device.

Compared with traditional light sources, LED point light sources are small in size and light in weight. They can be made into devices of various shapes to facilitate the arrangement and design of various lamps and equipment, with strong adaptability and a wide range of applications. Good environmental performance. Since the LED light source does not need to add metal mercury in the production process after the LED is discarded, it will not cause mercury pollution, and its waste can almost be recycled, which not only saves resources but also protects the environment. The safe and stable LED light source can be driven by low-voltage direct current, and the general power supply voltage is between 6~24V, so the safety performance is relatively good, especially suitable for public places. In addition, under good external environment conditions, LED light sources have lower light decay and a longer lifespan than traditional light sources. Even if they are frequently switched on and off, their service life will not be affected.
