Adjustable LED lamp with rotatable LED tubes

1. A LED lamp, comprising:

a sleeve;

a female joint received in the sleeve;

a pluggable connector rotatably connected to the sleeve;

a LED tube connected to the pluggable connector; and

a male joint received in the pluggable connector and engaging the female joint;

wherein the pluggable connector is provided with a plurality of clips on an outer sidewall thereof extending towards the LED tube, each clip is provided with a protrusion, the sleeve defines an annular groove on an inner wall thereof, the protrusion is latched in the annular groove when the pluggable connector is inserted into the sleeve, thereby preventing the pluggable connector from disengaging from the sleeve.

2. The LED lamp according to claim 1 , further comprising a connector positioned in the sleeve, wherein the female joint is positioned in the connector, the sleeve is provided with an annular portion on an inner wall thereof, the connector is provided with a plurality of elastic arms extending from an outer wall thereof, the elastic arm is provided with an anti-detachment barb, the connector is further provided with a resisting portion protruding from the outer wall thereof, such that the annular portion is latched between the anti-detachment barb and the resisting portion when the connector is inserted into the sleeve.

3. The LED lamp according to claim 2 , wherein the resisting portion has an annular shape and surrounds the outer wall of the connector.

4. The LED lamp according to claim 1 , wherein the pluggable connector is provided with a base plate at an end thereof adjacent to the LED tube, the LED tube is detachably connected to the base plate.

5. The LED lamp according to claim 4 , wherein the LED tube is provided with a support at an inner wall thereof extending along a longitudinal direction of the LED tube, the base plate is detachably connected to the support via threaded fasteners.

6. A LED lamp, comprising:

an assembly bracket;

a plurality of tube couplings rotatably connected to the assembly bracket;

a sleeve fixed to an outer wall of the tube coupling;

a female joint received in the sleeve;

a pluggable connector rotatably connected to the sleeve;

a LED tube connected to the pluggable connector; and

a male joint received in the pluggable connector and engaging the female joint;

wherein the pluggable connector is provided with a plurality of clips at an outer wall thereof extending toward the LED tube, each clip is provided with a protrusion, the sleeve defines an annular groove in an inner wall thereof, the protrusion is latched in the annular groove when the pluggable connector is inserted into the sleeve, thereby preventing the pluggable connector from disengaging from the sleeve.

7. The LED lamp according to claim 6 , further comprising a supporting rod and a locking nut, wherein the supporting rod comprises a first end and a second end positioned opposite to the first end, the first end is detachably connected to the assembly bracket, the plurality of tube couplings are sequentially sleeved on the supporting rod, the locking nut is located on the tube coupling away from the assembly bracket, and the locking nut resists the second end.

8. The LED lamp according to claim 7 , wherein at least one tube coupling is provided with a pluggable connecting portion extending from an end of the tube coupling, the pluggable connecting portion surrounds a central axis of the tube coupling, the tube coupling defines a containing groove at an opposite end, the pluggable connecting portion of the tube coupling rotatably extends into the containing groove of an-adjacent tube coupling.
