Desk lamp is a kind of light fixture, is mainly placed on desk or dining table, and is used for illumination, is convenient to read, study, saves energy. The current table lamps are generally divided into two types, one is column type, and the other is sandwich type. The bulbs used include incandescent lamps, energy-saving bulbs and eye protection lamps popular on the market. Some table lamps also have "emergency function" that is, automatic With power supply, it is used for emergency lighting in case of power failure.

On the other hand, because of its beautiful appearance, various materials and styles, table lamps often play the role of embellishing space, and its decorative function is equally important as its lighting function. On some occasions, the table lamp has become a rare work of art. Under the concept of light decoration and heavy decoration, the decorative function of the table lamp is more obvious.

The control methods of the common desk lamps on the market mainly include touch-control and brightness-adjustable. Among them, the principle of the touch desk lamp is to install an electronic touch IC inside and form a control circuit with the electrode sheet at the touch point of the desk lamp. When the human body touches the sensing electrode, the touch signal is generated by pulsating direct current to generate a pulse signal and sent to the touch sensing terminal, and then the touch sensing terminal will send out a trigger pulse signal to control the light on. The working principle of the brightness-adjustable desk lamp is a resistance-capacitance phase-shifting circuit composed of a resistor, a potentiometer, and a capacitor. By adjusting the potentiometer, the switch and brightness of the bulb can be changed.

The above-mentioned LED light sheet 31 is movably installed on the light pole 2 through the connecting portion 32 at the edge of the light sheet, and each light sheet is also connected to each other through the connecting portion 32 .

As shown in FIG. 2 , the above nine LED light sheets can rotate around the light pole 2 . Among them, in the process of turning on the light, the first light piece rotates at a certain angle α and then turns on the power to light up, and at the same time starts to drive the second light piece to rotate, making it rotate at an angle α to light up and drive the next light piece to rotate; accordingly By analogy, until the required number of lamps are lit or all of them are lit. When it is necessary to turn off the desk lamp, reversely rotate the first lamp sheet to drive the rest of the lamp sheets to reversely rotate and turn off one by one until returning to the initial state. Preferably, in this embodiment, the rotation angle α=40 degrees.

In this manner, the operator can conveniently turn on the desk lamp in the dark, which improves the user experience. On the other hand, the overall brightness of the desk lamp can be adjusted by controlling the number of lighted lamp pieces, and the operation is very convenient.
