Patent ID: 8556463

Claim:
A simple detachable illumination lamp tube, comprising: a tube unit having a light-permitting hollow tube; a heat-dissipating unit having at least one heat-dissipating substrate received in the light-permitting hollow tube, wherein the at least one heat-dissipating substrate has two opposite lateral sides contacting the inner surface of the light-permitting hollow tube; a light-emitting unit having a plurality of strip light-emitting modules received in the light-permitting hollow tube, wherein the strip light-emitting modules are detachably disposed on the at least one heat-dissipating substrate and electrically connected in sequence, and each strip light-emitting module has a circuit substrate, a plurality of light-emitting elements electrically connected and disposed on the circuit substrate and a package resin disposed on the circuit substrate to cover the light-emitting elements; a support unit having a plurality of support elements received in the light-permitting hollow tube and disposed on a bottom surface of the light-permitting hollow tube, wherein each support element is positioned between the bottom surface of the at least one heat-dissipating substrate and the inner surface of the light-permitting hollow tube; and a lateral cover unit having two lateral covers installed on two ends of the light-permitting hollow tube, wherein each lateral cover has a cover body and at least two conductive pins passing through the cover body and respectively electrically connected to the light-emitting unit.
