Claim:
1. A LED light-emitting device, comprising: a carrier, which is a transparent body, and conductors are provided on a carrying surface of the carrier; a plurality of LED chips, the number of the LED chips is N, the number of the conductors is N+1, where N is an integer larger than 1, and the N LED chips and the N+1conductors are alternately arranged along an extension direction of a pair of electrodes; chip soldering pads are provided at both ends of a bonding surface of each LED chip, circuit soldering pads are correspondingly provided at two ends of two conductors adjacent to the LED chip, and shape of the chip soldering pads corresponds to that of the circuit soldering pads; each LED chip and two conductors adjacent thereto are electrically connected by soldering the chip soldering pads with the circuit soldering pads by way of eutectic bonding, so as to realize electrical connection among the plurality of LED chips; a pair of electrodes, wherein positive/negative electrodes of the pair of electrodes are electrically connected, by means of the conductors, to the LED chips located at the most upstream/most downstream of a current transmission in the plurality of LED chips, and extend to the outside of the encapsulation structural member.
