<p>Lately, the importance of green industries for energy saving has been increasingly emphasized and distribution of LED lamps have become active as part of the energy saving. However, conventional fluorescent lamps made of a glass tube are not actively replaced with LED lamps because removing a ballast of the conventional fluorescent lamp and installing an LED converter is hard work. Since an LED lamp of the present invention uses AC power outputted from the ballast of the conventional fluorescent lamp to drive the LED lamp, it is possible to complete installation of the LED lamp by replacing the glass tube of the conventional fluorescent lamp with an LED lamp while using other luminaire components, including the ballast for fluorescent lamp, continuously. Moreover, the LED lamp of the present invention can maintain power consumption at a constant amount even if an input AC voltage increases to 250-260 V.</p> |
