A LED LIGHTING FOR SEA GUIDANCE LIGHTING

摘要

PURPOSE: An LED device for a sea guidance lamp and a remote control system are provided to enable a user to efficiently control an intelligent LED device at a remote place by using a USN based wireless network. CONSTITUTION: A SMPS(Switched-Mode Power Supply)(20) supplies DC power to an LED panel. A pulse control circuit(30) comprises a low power MCU. An oscillation circuit provides an oscillation signal to the pulse control circuit. A frequency setting circuit provides a frequency setting signal to the pulse control circuit. An illumination sensor(60) transmits a measurement signal to the pulse control circuit by measuring brightness around the lamp. A current sensor transmits a measurement signal to the pulse control circuit by measuring the current consumption of the LED panel. A switching circuit(80) supplies a control signal from the pulse control circuit and power from the SMPS to the LED panel.
