Abstract

An LED lamps module is provided. The LED lamp module includes a plurality of LED lamps, a plurality of electric wires and a plurality of moisture-resisting members. In one embodiment of the present invention, each LED lamp includes a substrate with a circuit, at least one LED chip disposed on the substrate and connected with the circuitry electrically, a plurality of pins connected with the circuitry of the substrate electrically, and an encapsulant encapsulating the substrate, the LED chip and a portion of each pin. The electric wires are connected with the pins exposed. The moisture-resisting members encapsulat the pins exposed and a portion of each electric wire.

Claims

1. A light emitting diode (LED) lamp module, comprising a plurality of LED lamps, wherein each LED lamp comprises:

a substrate with a circuit;

at least one LED chip disposed on the substrate and connected with the circuit electrically;

a plurality of pins connected with the circuit of the substrate electrically;

an encapsulant encapsulating the substrate, the LED chip and a portion of each pin;

a plurality of electric wires connected with the exposed portion of the pins not surrounded by the encapsulant; and

a moisture-resisting member, encapsulating the bottom of the encapsulant, the exposed portion of the pins of the LED lamp and a portion of each of the plurality of electric wires.

2. An LED lamp module according to claim 1, wherein at least one LED lamp is a full-colored LED lamp.
