An LED fluorescent lamp (10) comprises a tubular lampshade (20), two lamp head covers (31, 33) mounted on two ends of the tubular lampshade (20), at least one power supply circuit board (40) located in the tubular lampshade (20), at least one LED substrate (51, 52, 53, 54) and at least one LED bracket (60) for fixing at least one LED substrate (51, 52, 53, 54). At least one LED (80) is encapsulated on at least one LED substrate (51, 52, 53, 54); each of the lamp head covers (31, 33) is provided with a plug (311, 331) connected with an external power supply socket; at least one power supply circuit board (40) is electrically connected with the plugs (311, 331), the LED substrate (51, 52, 53, 54) and the LED (80) encapsulated on the substrate; a gap (70) is formed between at least one LED substrate (51, 52, 53, 54) and at least one power supply circuit board (40). The LED fluorescent lamp (10) does not directly generate heat transfer between the LED substrate (51, 52, 53, 54) and the power supply circuit board (40), so as to protect the LED substrate (51, 52, 53, 54). |
