Patent ID: 8556454

Claim:
A light tube, comprising: a heat sink, having a carrying surface; a light transmissive cover, disposed on the heat sink, wherein a containing space is formed between the heat sink and the light transmissive cover, and the carrying surface faces the containing space; at least one light source module, comprising: a carrier, disposed on the carrying surface and located within the containing space; a plurality of first light-emitting devices, arranged on the carrier along a first straight reference line, so as to form a first line of light-emitting devices; a plurality of second light-emitting devices, arranged on the carrier along a second straight reference line, so as to form a second line of light-emitting devices, wherein a separation space is kept between the first line of light-emitting devices and the second line of light-emitting devices; a plurality of non-light-emitting passive devices, disposed on the carrier and located within the separation space, wherein the non-light-emitting passive devices are electrically connected to the first light-emitting devices and the second light-emitting devices; and a connector, and the connector comprises: an insulation base, disposed on the carrier and located within the containing space, wherein the carrier has a first end and a second end opposite to each other, and the insulation base is disposed on the first end; and two electrode poles, wherein a part of each of the electrode poles is inserted into the insulation base, and another part of the electrode pole is extended out of the containing space, and the electrode poles are electrically connected to the first line of light-emitting devices and the second line of light-emitting devices; and an insulation pad disposed at one end of the containing space, wherein the insulation pad comprises: a non-axial-symmetric protrusion, protruded away from the containing space; and two third through holes, running through the protrusion and the insulation pad, wherein the two electrode poles of the connector are extended out of the containing space respectively through the two third through holes.
