Abstract

A light module includes a lighting unit, a heat-dissipation plate and an insulative plate. The lighting unit has a leading contact. The heat-dissipation plate contacts the lighting module closely and has a channel corresponding to the leading contact. The insulative plate is disposed under the heat-dissipation plate, and has a predetermined conductive pattern arranged thereon and a through hole corresponding to the channel. The leading contact of the lighting unit penetrates through the channel of the heat-dissipation plate and the through hole of the insulative plate to electrically connect with the predetermined conductive pattern of the insulative plate.

Claims

1. A light module comprising:

a lighting unit having a lead contact;

a heat-dissipation plate having opposing sides and an outer edge portion extending transversely therebetween, one of said sides being contiguous said lighting unit, said heat-dissipation plate having a channel corresponding to the lead contact, said heat-dissipation plate further having screw threads formed circumferentially about the outer edge portion thereof; and

an insulative plate disposed on said heat-dissipation plate side opposing said lighting unit , and having a predetermined conductive pattern arranged thereon and a though hole corresponding to the channel;

wherein the lead contact of the lighting unit penetrates through the channel of the heat-dissipation plate and the through hole of the insulative plate to electrically connect to the predetermined conductive pattern of the insulative plate.

2. The light module as claimed in claim 1, wherein the lighting unit includes an LED.

3. The light module as claimed in claim 1, wherein the lighting unit is fixed to the heat-dissipation plate.

4. The light module as claimed in claim 1, wherein the channel of the heat-dissipation plate is adjacent to the lighting unit, and the lead contact extends downwardly to penetrate the channel.

5. The light module as claimed in claim 1, wherein the channel is spaced from the lighting unit with a predetermined distance, and the lead contact extends outwardly along the predetermined distance and folds downwardly to penetrate the channel.

6. The light module as claimed in claim 1, wherein the insulative plate is made of polypropylene materials.
