Abstract
The present invention provides an LED module and an LED light string using the same. The LED module has an input terminal, an output terminal, a primary LED, a spare LED and a switching module. The switching module controls the spare LED to be switched off while the primary LED is switched on; and controls the spare LED to be switched on while the primary LED is burned out. Hence, the present invention extends a service life of the LED light string using the LED modules in the backlight module.
