Abstract

The invention discloses an LED lamp longer in service life. The LED lamp comprises a cylindrical LED lamp tube. The LED lamp is characterized in that a printed circuit board (PCB) substrate which penetrates through the LED lamp tube is arranged in the LED lamp tube in the diameter direction of the cross section; a plurality of LED bulbs are arranged on the PCB substrate; a heat-conducting cushion is arranged on the other side of the PCB substrate; a heat dissipation plate is arranged on the heat-conducting cushion, and cooling fins are arranged on the heat dissipation plate and are wavy; transverse through holes are formed in the cooling fins; air holes are formed in the wall of the LED lamp tube, and the air holes include the illumination end air holes and the heat dissipation end air holes. The LED lamp longer in service life has the beneficial effects that through the combination of the illumination end air holes and the heat dissipation end air holes formed in the LED lamp and the wavy cooling fins provided with the transverse through holes, the heat dissipation effect can be improved, the internal temperature of the LED lamp is effectively decreased, and the service life of the LED lamp can be prolonged.
