The LED lamp is supported by a support assembly to prevent the LED lamp from falling. In addition, when the support assembly can be used to support the ceiling, the support assembly can slide relative to the ceiling, thereby rotating the LED lamp. The first shell and the second shell 3 can rotate relative to each other, thereby adjusting the direction of the light source part, thereby adjusting the irradiation angle; combined with the rotation of the above-mentioned LED lamp, it is possible to adjust the LED lamp to irradiate in multiple directions.

Through the setting of the second channel, the heat can be guided to move upward along the second channel. After the heat is transferred to the radiator, the heat can be transferred to the outside world via the radiator.

By setting the second grooves, the contact area between the base plate and the branch plate and the outside air can be effectively increased, thereby improving the heat dissipation efficiency.

[0030] The first shell and the second shell 3 can rotate relative to each other to adjust the illumination angle of the LED light. In some embodiments, the first shell is arranged in a circular ring shape, and a vertical first channel is formed inside the circular ring-shaped first shell. The second shell 3 is arranged in the first channel, and the second shell 3 and the first shell are connected by a rotating shaft 31. The first shell and the second shell 3 are connected by the rotating shaft 31, and there is friction between the first shell and / or the second shell 3 and the rotating shaft 31. After the first shell and the second shell 3 rotate relative to each other, the static friction generated by the rotating shaft 31 maintains the angle of the first shell and the second shell 3 after relative rotation.

[0031] The support assembly is used to support the top surface of the ceiling. For the convenience of installation, in some embodiments, the support assembly includes a first torsion spring arm 41, a second torsion spring arm 42, a first mounting frame 43 and a second mounting frame 44.
