LED LIGHING SYSTEM FOR GROWTH PROMOTION

摘要

PURPOSE: An LED(Light Emitting Diode) system is provided to reduce manufacturing costs and installation costs by replacing an incandescent lamp with an LED bulb. CONSTITUTION: An LED unit(100) comprises an LED substrate and a support unit(120). A plurality of LED elements is mounted on an LED substrate. The support unit supports the LED substrate. A power connection unit(220) is connected to a commercial power source(210). An LED controller(300) includes a DC converter and a DC controller. The DC converter is connected to the power connection unit to convert AC into DC. The DC controller controls at least one of current and voltage applied to the LED element. A power connection cable(230) connects an LED controller and an LED unit in parallel or series.
