Patent ID: 8587001

Claim:
A light-emitting diode (LED) light module free of jumper wires comprising: a substrate having: a positive side circuit formed on a surface of the substrate; a negative side circuit formed on the surface of the substrate; at least one first chip connection portion juxtaposedly formed on the surface of the substrate and connected to the positive side circuit; at least one second chip connection portion juxtaposedly formed on the surface of the substrate and connected to the negative side circuit, wherein the at least one second chip connection portion and the at least one first chip connection portion are alternately arranged on the substrate in a longitudinal direction of the substrate, and each one of the at least one second chip connection portion and a corresponding one of the at least one first chip connection portion are spaced with a first gap; and a solder mask layer formed on and partially covering the at least one first chip connection portion and the at least one second chip connection portion for the at least one first chip connection portion and the at least one second chip connection portion to be partially exposed to respectively form multiple electrical contacts thereon; at least one LED chip, wherein a width of each one of the at least one LED chip is wider than the first gap between a corresponding one of the at least one first chip connection portion and a corresponding one of the at least one second chip connection portion, and each one of the at least one LED chip is mounted on the electrical contact of a corresponding one of the at least one first chip connection portion and on the electrical contact of a corresponding one of the at least one second chip connection portion; a frame mounted on the substrate to surround the at least one LED chip; and an optically-transmissive adhesive layer mounted within the frame to cover and contain the at least one LED chip therein.
