In this paper, we constructed using a Cortex M3 microcontroller developed by ARM Inc. as a way to control the LED light more efficiently. And Using the short-range wireless communication by the Bluetooth communication method applied to control the LED light was configured to wirelessly control the wireless circuits. In this paper, users can easily download and easy to wirelessly control the LED lighting control circuit to design an Android application from Android-based smartphone so that you can control with your smartphone to have anyone to control the LED lighting control circuit wirelessly. If the LED lights radio control circuit is configured with the Cortex M3 in this paper is applicable to both indoor and outdoor and eco-friendly technology, is using LED driver to enhance the efficiency of the LED becomes stable voltage supply is made, the brightness of LED lighting control.

This paper performs Color Code Control Connected with Sound Source and Sensitivity of PA Speaker facility attachable LED patch. PA speaker delivers the technology to control the color code of LED patch along the present PA speakers for the facility-attached, LED the development of the patch. PA speakers facility attachable color code control technology of LED patch detects the sound from the PA speaker using a check, and if the analog signal source is detected (sound source)by converting the digital signal passes to the main controller can control the color and pattern of LED patches. In this paper, based on the PA speakers LED color control system, sound emotional linkage-type, and follow the lead of the PA speakers through the feelings can effectively channel LED linked to the source type and proceed to experiment with color and emotion control, whether or not they offer via the color control technology LED patch availability. PA speaker facility attachble color code control technology of LED patch connected with the source and future research directions in the field, and as the application is expected to be able to be widely utilized.

An LED lighting control system was developed to combine information technology and LED lights for efficient management and energy savings. The system can monitor and control the status of an LED luminaire using Bluetooth wireless communication, sensor technology, and smart phones. An LED lighting control circuit was designed using a temperature sensor, illumination sensor, and Bluetooth module with a fuzzy constant-current control circuit. We extended the lifetime and prevented damage to the LED by optimizing the supply current of the LED luminaire based on the heat-generation temperature of $70^{\circ}C$ of an LED heat sink. We also automatically adjusted the ON/OFF time depending on the ambient illumination of the LED luminaire. By allowing easy control of the LED luminaires on a smartphone, we improved the efficiency and achieved energy savings. The control system was validated through experiments for normal operation.

Automotive headlamp with LED matrix exploits low-cost low-speed serial buses such as I2C and SPI for digital LED control. When headlamp resolution increases, LED control data significantly increases to exceed capacity of control bus. This paper proposes HLCP (Headlamp LED Control Protocol), a novel LED maxtrix headlamp protocol. The proposed protocol exploits dedicated instructions to control many LEDs simultaneously, so it can control much more LEDs than conventional control buses although it is basically based on I2C bus. It is designed and verified in Verilog HDL. Simulation results show that HLCP can control LED matrix headlamp more efficiently than I2C and SPI.

본 논문은 실생활에서 많이 사용되는 LED 전광판을 제어하는 안드로이드 기반 응용프로그램과 그 설계방법에 대한 연구이다. 일반적으로 LED 전광판에는 PC가 붙어 있어서 LED 전광판에 표시할 내용을 설정하고 제어하는 역할을 한다. 반면, 본 연구에서는 LED 전광판을 제어하는 서버를 스마트폰으로 제어할 수 있도록 안드로이드 기반 응용프로그램을 개발하였다. 이를 통해 사용자는 전광판을 제어(켜고/끄는 등)하거나 전광판의 내용을 바꾸고자 할 때, 언제 어디서나 편리하게 이를 조작할 수 있다.
