Abstract
A lamp tube according to the present invention at least comprises: a tube body, a light-emitting module, a driving module and an electrical connection module. The light-emitting module and the driving module are disposed in the tube body. The light-emitting module is provided with a first circuit board and a plurality of LEDs. The driving module is provided with at least a second circuit board and a drive circuit. The electrical connection module forms an electrical connection between the first and second circuit boards. It is convenient to independently replace or repair the driving module or the light-emitting module without discarding the entire lamp tube so as to effectively save costs and achieve the effects of energy saving and environmental protection.
