1. The LED controller series is a RGB three-color intelligent dimming controller dedicated to LED lighting, using advanced computer control chips and the most advanced PWM (pulse width modulation) digital brightness adjustment technology; it can be remotely controlled by IR/RF Comes remote dimming; can meet the light needs of commercial or home lighting at different times and in different environments, extend the life of LEDs, and save energy; it has the advantages of convenient wiring and simple use. According to the actual needs of customers, it can achieve lighting changes such as jumping and gradual .
2. Overview Edit the Led controller, use MCU, DSP, FPGA, etc. as the processor, add interface I/O circuits, write the corresponding program code, and process the protocol of the LED drive chip to realize the control of the switching volume and the PWM duty cycle , Realize full-color changes, and can display animation, such as flowing water, gradual change, jump, video, etc.
3. Main features
●Using RF 2.4GHZ wireless transmission technology, the frequency band is free of license and royalty-free use internationally;
●The kernel is upgraded to dual-core driver, which brings processing speed up to 10 times faster, and can handle complex multi-level wireless data transmission; leading RF wireless synchronization control technology, no synchronization signal line between controllers, stable and reliable synchronization performance;
●Realize the unlimited number of receiving controllers to synchronize the lighting changes, and solve the problem of places where the controllers cannot be pulled but need to be controlled synchronously; ·The remote control adopts a capacitive full-color ring touch method, and the LED color selection is more user-friendly, which can theoretically produce Billion colors;
●Operating the remote control or any one of the controllers can command all the controllers to work synchronously wirelessly. At present, only LTECH products have this function; ●Color and light change scene mode preset storage function;
●Built-in USB charging port.

Six, controller classification
Online controllers include H801TV and H802TV. H801TV and H802TV are online master controllers that transmit data through DVIV/HDMI interface, and the supporting sub-controllers are H801RA and H801RB. Each H801TV can control up to 786,432 (780,000) pixels, and each H8O2TV can control up to 300,000 pixels. H802TV supports copy mode, while H801TV does not, but supports any shape of LED lamps.
Offline controllers include H802SA, H802SB, H801SC, H802SC, H801SD, H801SE, H802TA, H802TB, H801TC.H802TC, H804TC. Both H8O2SA and H801SE are single units with four-port output, H802SB is a single-port output controller with infrared remote control, H801SC and H802SC are power-synchronized single-units, and H801SD is a single-unit with eight-port output. H801TC is the main control for power synchronization, H802TA is the main control with GPRS function, H802TC is the main control with GPS synchronization function, and H804TC is the main control with RF synchronization. The main controller needs to be used together with the sub-controller H801RA or H801RB.
Linkable and detachable controllers include H801RA, H801RB, and H803TC. H8O1RA and H801RB are sub-controllers, used together with the offline master control to form an offline system, and used with the online master control to form an online system, and can also be directly connected to the computer network port. H803TC can receive data from the computer network port, and can also read data from the SD card and send it to the sub-controller.
Seven, the quality control of the LED controller, the production process of the LED controller is composed of multiple processes, including SMT process and DIP plug-in process, so it is very important in quality control testing. Generally, manufacturers use two testing methods. One is SMT patch surface inspection-AOI optical inspection, and the other is electrical performance inspection.
