Patent
CA 2503416
The invention discloses an LED lamp and an LED lamp set having a load connected to both ends of an LED, and the lamp acts like a non-polarized lamp to an alternate current and maintains to be half wave lit. No consideration of anode and cathode is needed for connecting the LEDs of the lamp set in series on an electric wire. Even when an LED is damaged to produce an open circuit, electric current still can pass through the load connected to the damaged LED to light up the rest LEDs. Since the LED will not be damaged easily while blinking, the LED has a long life. It is not necessary to consider the polarity of the LED for its installation, and thus making the installation and replacement more convenient. The invention comes with a voltage divider or choke that can resist voltage or current surges.
