An LED lamp comprises a lamp bracket (1) and a lamp tube (2). The lamp tube (2) is sleeved with the lamp bracket (1) and internally provided with a bracket (3), which is a long column and has a semi-circular ring-shaped cross section with radian of larger than or equal to 180 degrees. The bracket (3) is in tight fit with the upper end of the internal surface of the lamp tube (2). Two grooves (30), which also have long column shape, are provided at a lower end of the bracket (3), where opening directions of the two grooves (30) are opposite to each other. The grooves (30) are internally sleeved with an aluminum-based circuit board (4), on which LED lighting chips (5) are arranged in array. The long column shaped bracket (3) improves the connection reliability and impact resistance property of the lamp. |
