Abstract

Providing an LED lamp module and a method of manufacturing the module preventing deformation and having more freedom for disposing the module, an LED chip for light source, lead terminals having electric-wire pressure contact to be connected with electric wires 39 and supplying source current to the LED chip, an LED lamp 15 including a resin lens 20 sealing the LED chip, and a lamp holder 23 holding the LED chip 15 are molded integrally. Preferably, the resin lens 20 and the lamp holder 23 are molded with different synthetic resin materials by double molding. A connector to be connected with a mating connector is formed at the lamp holder and tab-like terminals continued to the lead terminals project into the connector.

Claims

1. An LED lamp module comprising:

an LED lamp having an LED chip for a light source, a plurality of lead terminals being connected with the LED chip and a resin lens sealing the LED chip; and

a lamp holder for holding the LED lamp,

whereby the LED lamp and the Lamp holder are molded integrally.

2. The LED lamp module according to claim 1, wherein the lead terminal is provided with a pressure contact portion having a U-shaped slit, to be connected with electric wires.

3. The LED lamp module according to claim 1 or 2, wherein the lamp holder includes a base and a cover to press the electric wires, wherein the cover is removably coupled to the base.

4. The LED lamp module according to claim 1, wherein the lamp holder is provided with a connector to be connected with a mating connector at a power supply side, and the connector has an electric contact continued to the lead terminal.

5. The LED lamp module according to claim 1, 2, 3 or 4, wherein the lamp holder and the resin lens are made of two different colors of synthetic resigns.

6. A method of manufacturing the LED lamp module, according to any one of claims 1-5, comprising the steps of:

forming the lead terminal by punching an electrical conductive plate in accordance with a predetermined circuit pattern and by bending the plate if required;

assembling a bus bar circuit by bonding the LED chip to the lead terminal;

molding the resin lens so as to seal the LED chip to form the LED lamp; and

molding the lamp holder to hold the LED lamp by inserting the LED lamp between upper and lower dies.

7. A method of manufacturing the LED lamp module, according to any one of claims 1-5, comprising the steps of:

forming the lead terminal by punching an electrical conductive plate in accordance with a predetermined circuit pattern and by bending the plate if required;

assembling a bus bar circuit by bonding the LED chip to the lead terminal;

inserting the bus bar circuit between upper and lower dies; and

molding the resin lens for sealing the LED chip and the lamp holder for holding the resin lens simultaneously.
