The utility model relates to a LED fluorescent tube that throws light on with night light function, including the fluorescent tube body, the fluorescent tube body includes PCB board and transparent cover, and evenly distributed has a more than one LED chip on the PCB board, the both ends of PCB board are equipped with and make the LED chip get the binding post that electric conductance leads to after the grafting of fluorescent tube body is on the lamp stand, transparent cover wraps up seal structure of constitution with LED chip and PCB board, and binding post is located the transparent cover both sides, and transparent cover includes has the silver -colored photosphere of taking tombarthite inorganic material inboard bonding of lamp shade body by the lamp shade body. The utility model discloses a problem of traditional emergency lighting, little night -light reliance power has been solved, because need not to consider the enough time of to shine and to give out light, give off light in order to let luminescent material absorb sufficient light and heat under the light source, so in case under the condition that emergence outage or emergency power were unable to supply, also can realize instructing at simple emergency, night the illumination effect to sustainable luminous more than 10 hour.
