LED LAMP, AND METHOD OF DRIVING AT LEAST ONE LED STRING THEREOF |
摘要 |
The Light Emitting Diode (LED) lamp is adapted for mounting in a fluorescent tube mount having a selectively activatable magnetic ballast powering two pairs of sockets with AC power upon activation. The LED lamp has a body having connectors at both opposite ends adapted to the corresponding pair of sockets, at least one LED string extending along at least a portion of the body, a driver inside the body connecting the connectors to the LED string, the driver including a transistor, an inductor, and a rectifier in a switch mode converter configuration, for converting the AC power of the sockets into a DC power of a voltage adapted to power the LED string; and a pulse mode controller for controlling the transistor in an intermittent manner upon activation of the multiple fluorescent tube mount, until conduction across the at least one LED string is achieved. |
