如图 3至图 4所示， 图 3是本发明一优选实施例的 LED灯管的分解状态的 截面放大图，图 4是本发明一优选实施例的 LED灯管的组装状态的截面放大图。 承载基板 11上间隔设置有多个用以照明的 LED 110。灯座 13包括靠近承载基板 11的第一侧壁 131及远离承载基板 11的第二侧壁 132。 在本实施例中， 灯座 13 为中空的半圓柱形。 灯座 13的第一侧壁 131为半圓柱形的平面， 第二侧壁 132 为半圓柱形的柱面， 第一侧壁 131和第二侧壁 132定义一容置空间 134。 灯座 13优选由长条状铝挤型材制成， 且其外表面可设置有散热鰭片， 以提高散热效 果。  3 to FIG. 4, FIG. 3 is an enlarged cross-sectional view showing an exploded state of an LED lamp according to a preferred embodiment of the present invention, and FIG. 4 is an enlarged cross-sectional view showing an assembled state of the LED lamp of a preferred embodiment of the present invention. . A plurality of LEDs 110 for illumination are disposed on the carrier substrate 11 at intervals. The socket 13 includes a first sidewall 131 adjacent to the carrier substrate 11 and a second sidewall 132 remote from the carrier substrate 11. In the present embodiment, the socket 13 is a hollow semi-cylindrical shape. The first side wall 131 of the socket 13 is a semi-cylindrical plane, the second side wall 132 is a semi-cylindrical cylinder, and the first side wall 131 and the second side wall 132 define an accommodation space 134. The socket 13 is preferably made of a strip of aluminum extruded material, and the outer surface thereof may be provided with fins to improve the heat dissipation effect.
电源 15设置于容置空间 134内， 且包括电源壳体 150以及设置于电源壳体 150内的电源电路板（未图示）。 在本实施例中， 电源壳体 150包括 U形的顶壳 155以及底壳 156, 顶壳 155与底壳 156相配合以收容电源 15的电源电路板。 电源壳体 150的两侧设置有侧肋 154,容置空间 134的内表面形成有用于接收侧 肋 154的插槽 135 , 以允许电源壳体 150沿灯座 13的延伸方向滑动。  The power source 15 is disposed in the accommodating space 134 and includes a power source housing 150 and a power circuit board (not shown) disposed in the power source housing 150.
