LED灯用电源装置及LED灯系统
摘要：
本发明公开一种LED灯用电源装置及LED灯系统。本发明提供能可靠地进行LED灯的安装检测的LED灯的专用电源。专用电源(15)具有直流电源部(35)。专用电源(15)具有点亮电路(36)，该点亮电路(36)接收来自直流电源部(35)的供电，并对具有LED元件(25)及与LED元件(25)并联连接的检测用电阻器(26)的LED灯(14)进行点亮控制。专用电源(15)具有安装检测部(37)，该安装检测部(37)基于根据LED灯(14)的装拆所引起的检测用电阻器(26)的装拆而变化的电压电平，检测出有无安装LED灯(14)。
摘要（英）：

A dedicated power source for LED lamps capable of reliably detecting attachment of an LED lamp is provided. A dedicated power source (15) has a DC power source portion (35), and includes a lighting circuit (36) which receives power supplied from the DC power source portion (35) and light-controls an LED lamp (14) including an LED element (25) and a detection resistor (26) connected in parallel to the LED element (25) and an attachment detecting portion (37) for detecting attachment of the LED lamp (14) based on a voltage level changing in accordance with attachment/detachment of the detection resistor (26) by attachment/detachment of the LED lamp (14).
