An LED light fixture includes a first substrate, a second substrate and a plurality of LED chips. The first substrate, on one side thereof, includes a plurality of spaced first electrodes, a first inner terminal electrically connected to the first electrodes, and a second inner terminal insulated from the first electrodes, and, on another side thereof, a first outer terminal electrically connected to the first inner terminal and a second outer terminal electrically connected to the second inner terminal. The second substrate includes a plurality of spaced second electrodes corresponding to the first electrodes, and a third inner terminal electrically connected to the second electrodes and the second inner terminal. The LED chips are arranged between the first and second substrates and electrically connected to the first and second electrodes of the first and second substrates, respectively.
