The invention provides a self-adjustable brightness LED lamp which is easy to move, which includes a lamp tube, a bulb, a wiring chamber, a winch, a photosensitive resistor, a thermistor and a heat pipe. The bulb is installed on the right side of the lamp tube, and the winch is connected by a hinge shaft. Inside the wiring harness room, this design is convenient for the user to move the invention, which solves the problem that the original LED lamp cannot be moved, and the user cannot take it to the hand for lighting, which affects the normal use of the residents. On the upper end of the lamp tube, the thermistor is assembled inside the lamp tube, the battery is connected to the switch through wires, and the heat pipe is connected to the thermistor. This design solves the problem that the original LED lamp cannot adjust the brightness by itself. If the user forgets to When the power is cut off, the LED light keeps emitting light, which wastes electric energy, and when the LED light is continuously used, it will generate heat and increase the internal temperature, which will cause damage to the internal parts of the LED light. This invention saves resources, has comprehensive functions, is easy to move, and is practical Strong.
