Discuss that LED lights control system
Main application of LED lights control system
1 LED pixel source: application of LED color screen display principle, the pixel amplification,reducing the overall cost, each led pixel module is a color pixel. Application environment bar,KTV,stage,exhibition hall, shopping malls, as the music melody display background wall decoration, wall advertising etc.

2 LED rainbow tube: each lamp is composed of a plurality of color pixels(RGB)composition, each monochromatic pixel cann produce 256 gray level changes, applicationEnvironment:decorative lighting overpass guardrail,river,building walls and other different places.

The hardware system design
LED lights control system mainly includes a drive module, control module ,LED power supply three part:

*Drive module
The drive module output 256 grayscale colors to achieve color display gray controller only need to transfer the module of RGB color value can realize color display the drive module is I2C bus control programmable PWM outputs of the LED four bit, mainly used in the LEDRGB/RGBA(Red/Green/Blue/Amber)mixed.

*Control module
The main role of control module is through the MCU to control all dimmer module one the I2C bus, in order to achieve a variety of display effect,used to improve the ability of the bus driver, transmission rate in the 20~50kbps, transmission distance can reach 1km.MCU can be selected according to the actual system requirements, can also join otherOperations while dimming control bus devices, such as displaying image processing,Communicating with the PC, expand storage space, and so on

* Power supply
power supply according to the amout of led, and connections and other factors to determine the specific parameters, anyway the design(the LED power solution) is simple, small size,wide rage voltage input, low-cost, advantages of low loss, and was widely used in LED field.

Engineer designed LED for their led project
LED pixel screen is composed of dmx controller and led module.
LED is an excellent component for led pixel display, the led has the main part in the LED pixel screen. It has the advantages of long service life, saving, high brightness, various colors, fast response and low drive voltage, the energy saving can also luminous intensity by adjusting LED PWM wave,
HOW to achieve the LED pix modules come in different colors, which rely on intermittent inertia principle of human vision use of R,G,B three color LED duty cycle to achieve color mixing The design scheme of the LED color display mainly rely on the I2C interface of LED control IC.It can make the PWM output to controlled pixel module. Or to regulate led pixel module by ISP transport protocols (such as DMX512 protocols).

Application of category for LED pixel

The first application of category:
First class: first class is the main application of pixel screen television, theater and other stage as a background screen, playing background video or animation, magnificent momentum, so the stage is more dynamic,there are many stage adoption. Cabaret music can be used to set up the screen, indoor walls, energetic and colorful ceiling, user can play the animation, you can dance with the music, and so can the subtitles. Home decoration also uses dynamic colorful ceiling, you can always adjust the room tone at any time, The light can dance with the music, both romantic and dynamic. Do not have a flavor. Make a mood for every one.

The second category: The main application is the LED pixel screen of the building wall and outdoor walls. Each the layers of the wall be building pixel lamp with larger spacing , it becomes a mega LED pixel screen.

Third Class: The application of Third Class is installed in the pixel light tiles, or a transparent floor, forming a pixel screen on the ground. Can be used in a hotel or large office building lobby, or the surface of the stage.

Fourth class: The application of Fourth class for the main music column, or bright ceiling. Can the overall change color, also can follow the music flow to dance. Can the setting on the wall, corner of a wall, also can be the setting in the ceiling.
The romantic and dynamic atmosphere filling the full indoor  As the effect of the single music screen.

Pixel screen
A pixel screen introduction:

The pixel screen also known as the background screen. Mainly used in the stage background, indoor and outdoor wall, ceiling, colorful music screen, music column etc..Can also be used for building wall surface decorative lighting, wall screen. At the same time, the pixel screen is also core material application of colorful tiles, wall tiles (engineering business it can be installed in the transparent floor tiles, wall tiles within).Pixel screen is composed of a plurality of pixel lights module, a display pixel by pixel lamp is the screen. Pixel lamp interior has high brightness light-emitting diode only red, green, blue three colors (LED), the use of primary colors mixing principle, are controlled by a variety of LED’s brightness changes controller or IC (WS2801IC)to achieve pixel color change lights. This product has achieved full-color display.Pixel screen series products, compared with conventional LED electronic display screen。  pixel screen is the spread of LED electronic display screen, such as,number of pixels,, pixel screen area can be done several times (even a few times) display size than the LED electronic display , Imposing more spectacular sight distance farther.

To introduce some led name for led project
The LED market sells a variety of led product. Today we will talk about these led name.

Points of knowledge for LED pixel light source

In view of the market price of LED pixel point light source more choice, so we will be talk about LED pixel light source, can meet more know for the led pixel light source. LED point light source divide into the external control and internal control points base on the attribute of control, as the name suggests is internal control l mode which has been set up, the external control can add controller to control its running mode, it will increase the cost of external control.(such as WS2801IC)LED light source using an aluminum underpan, excellent heat dissipation, water resistance, ease of installation, simple control, the use of low-voltage power supply, safe and reliable, elegant appearance of the atmosphere, is building body, bridges outline, hotels, billboards, walls and lighting for night games ideal decorations.

LED pixel point source compare with LED rainbow tube
Now we will started on an analysis the application and control module of LED pixel point source and LED rainbow tube.

1 Application of point source : application of LED color screen display principle the pixel amplification. Reducing the overall cost, each module is a  color LED pixel.
Application environment, bar, KTV , stage ,exhibition hall , shopping malls , as the music melody display,Background wall decoration , wall advertising etc…

Control module of point source: According to the DMX512 protocol to bring up WS2801IC LED  pixel module through DMX controller.

2 Application of LED rainbow tube: each lamp is composed of color pixels(RGB) , each color pixel produces 256 gray levels change. Application environment decorative lighting overpass guardrail , river , building walls and other different places. The energy
saving can also luminous intensity by adjusting LED PWM devices. Control module of LED rainbow, base on the RGB　tricolor light mixing principle of regulating a variety of colors , and then control to achieve a display results by MCU intellgent.

LED backlight technology
According to the type of LED backlight technology(or category) division, it’s can be divided into RGB-LED and white light LED at present. White LED and RGB-LED both logic, all hope to achieve white light effect, only one is presented directly to the  white light show, another is based on the RGB color mixed light and.

According to the back light incident position division: LED backlight module（LED pixel） according to the light incident position is divided into direct type and side entering type two categories, can be divided into direct type RGB-LED, straight white LED, side light type white LED.

The working process of LED pixel lamp

LED pixel lamp with LED pixels of different colors to achieve from point to effects of surface dynamic, pixel lamp can calculate and received the signal or Instruction  from MCU(such as WS2801IC)
or computer. Then edit and set of figure and scene by Instruction, and can be real-time transmission of data, so as to realize the synchronous play with the computer monitor in real time Playback function, product mix can be simulated LED display effect, showing a variety of text, images and dreamlike dynamic effect.
