Abstract: A simple detachable illumination lamp tube includes a tube unit, a heat-dissipating unit, a light-emitting unit, a support unit and a lateral cover unit. The tube unit has a light-permitting hollow tube. The heat-dissipating unit has a heat-dissipating substrate received in the light-permitting hollow tube. The heat-dissipating substrate has two opposite lateral sides contacting the inner surface of the light-permitting hollow tube. The light-emitting unit has a plurality of strip light-emitting modules received in the light-permitting hollow tube. The strip light-emitting modules are disposed on the heat-dissipating substrate and electrically connected in sequence. The support unit has a plurality of support elements received in the light-permitting hollow tube and disposed between a bottom side of the heat-dissipating substrate and the inner surface of the light-permitting hollow tube. The lateral cover unit has two lateral covers installed on two ends of the light-permitting hollow tube.

Abstract: A lamp head assembly includes an outer head unit, an inner head unit, and an elastic pressing unit. The outer head unit includes at least two conductive pins. The inner head unit is disposed rotatably in the outer head unit. The elastic pressing unit is disposed movably in the outer head unit for selectively positioning the position of the inner head unit relative to the outer head unit or the position of the outer head unit relative to the inner head unit, wherein the elastic pressing unit includes a pressing element selectively exposed from the outer head unit.
