LED dot light source is a smart lamp that can replace the display screen of a certain specification by the color mixing of pixels. The smaller the distance between the points, the higher the pixel density. Closer. The larger the distance between dots, the lower the pixel density, the less the flashing information capacity per unit area, and the longer the distance for proper viewing.

01, LED dot light source

LED dot light source uses LED cold light source to emit light, built-in microcomputer chip, can be programmed and controlled, multiple simultaneous changes, small size, good environmental performance, safety and stability, shock resistance, good impact resistance, strong directivity, fast response time, light emitting efficiency High, rich light color, no flicker, no UV, good brightness adjustability, it is an ideal decorative lamp for buildings, bridge outlines, hotels, billboards, and curtain wall night scene lighting projects.

02 、 Classification of LED point light source

LED point light source is divided into two types: target point light source (Target Point) and free point light source (Free Point).

The target point light source can be used to project light to a target point. The distribution properties of the light point are isotropic, spotlight, and web.

The function of the free point light source is the same as the target point light source, but there is no target point, and the user can change the direction of the light by himself. Similarly, the free point light source also has the above-mentioned three properties of controlling light distribution.

Linear light sources are also divided into two types: target linear light sources (Target Linear) and free linear light sources (Free Linear). The target line light source can be used to project light onto a target object. The distribution properties of the light line are Diffuse and Web. The function of the free line light source is the same as the target line light source, but there is no target object, and the user can change the direction of the light by himself.

Similarly, a free-line light source also has the above-mentioned two properties of controlling light distribution. The diffuse distribution of the light will project the light to the surface with the maximum intensity at an angle, and the intensity of the light gradually decreases with the tilt of the angle. The web distribution type allows users to customize the emission intensity of the lights.

03. LED point light source has several advantages, as follows:

1. Small size and light weight, can be made into any shape, which is convenient for the arrangement and design of lamps and has a wide range of applications.

2. Fast response speed, its response time is nanosecond.

3. No flicker or UV. The LED point light source spectrum is mainly concentrated in the visible light region and will not be interfered by ultraviolet and infrared radiation, so it can effectively avoid flicker.

4. Strong shock resistance and shock resistance. LED point light source manufacturers use epoxy resin for sealing, so that it has strong waterproof and shock resistance. Excellent impact resistance also facilitates transportation and production.

5, environmental protection, LED point light source is made of non-polluting materials, and its waste can also be recycled.

6. The brightness is adjustable. The luminous brightness of the LED point light source can be effectively controlled according to the current. It is convenient to realize on-demand lighting and stepless brightness control.

7, strong directivity, the light emitted by the LED point light source is directional, most of the light can be directly directed to the illuminated surface. Compared with traditional light sources, the utilization rate is higher.

8. High luminous efficiency, low power consumption, long service life and low operating temperature.

9. The LED light source of the new fire lighting is safe and reliable.

10. Fast response speed, small unit volume, and environmental protection.

11. At the same brightness, the power consumption is one tenth that of incandescent lamps, one third of that of fluorescent lamps, but the service life is 50 times that of incandescent lamps, and 20 times that of fluorescent lamps. Fourth-generation lighting products.

12. The advent of a single high-power super-brightness LED makes it possible for the LED application field to cross the high-efficiency lighting source market.
