Table lamps are generally referred to as the table with the base of the lamp, but with the progress of technology, the appearance of the lamp, the shape is also evolving, and gradually appeared to be able to adsorb in any position of the magnetic table lamp, it is small and exquisite, easy to carry. The role of table lamps is mainly lighting, easy to read, study, work, etc. Table lamps have gone far beyond their value, and have even become artwork. Next, the introduction of table lamps will help you to further understand the table lamp.
Here is the content list:

Function introduction
Table lamps, according to the use of functional classification are reading table lamps, decorative table lamps, and portable table lamps.
Reading table lamp
A reading table lamp, which is simple and light in shape, refers to a table lamp specially used for reading and writing. This table lamp can generally adjust the height of the lamp pole, and the direction, and brightness of the light, mainly for lighting and reading.
Decorative table lamp
Decorative table lamps have a luxurious appearance, a variety of materials and styles, complex structure of the lamp body. It is used to decorate the spacing effect. The decorative function is as vital as the lighting function.
Category classification
Touchable table lamp
The principle of the touch-sensitive table lamp is to install an electronic touch IC inside the lamp, which forms a control circuit with the electrode at the touch of the lamp.
When the human body touches the sensing electrode, the touch signal is transmitted to the touch sensing end by the pulse signal generated by the pulsed DC, then the touch sensor will stop sending the trigger pulse signal, and when the AC power crosses zero, the light will naturally off.
However, sometimes after a power outage or voltage instability will also have a light-up situation, if the touch reception signal sensitivity is excellent paper or cloth can also be controlled.
Brightness adjustable table lamp
Adjustable desk lamp works by resistor R2, potentiometer RP1, and capacitor C to form a resistive-capacitance phase shift circuit, adjust RP1, you can change the conductivity angle of the two-way thyristor V, thus changing the brightness of the light bulb EL. Resistor R1 is the current limiting resistor, and the charging rate of C is also associated with the parallel circuit.
When R1 and RP2 are fixed, the shunt size is determined by the resistance of the photosensitive resistor RL. When the grid voltage rises, the light brightness increases, the RL resistance value becomes smaller, the shunt increases, the voltage across the capacitor C rises slowly, the thyristor V conduction angle decreases, the output voltage decreases, and the light brightness decreases; conversely, when the grid voltage decreases, RL resistance value increases, the shunt decreases, the thyristor conduction angle increases, the output voltage increases, the light brightness increases. The light illumination is automatically stabilized at the set value.
Remote control table lamp
The analog variable light table lamp and analog variable control center has a remote control on and off, a variety of lights adjustable at will, and a light automatic memory storage function.
