What does the floor lamp do?
Desk lamps are classified according to their functions: reading desk lamps, decorative desk lamps, companion desk lamps and portable desk lamps.
Reading desk lamp, simple and light in shape, refers to a desk lamp specially used for reading and writing. Generally, this desk lamp can adjust the height of the lamp post, the direction and brightness of lighting, and is mainly used for lighting reading.
Decorative desk lamps are luxurious in appearance, diverse in materials and styles and complex in structure. They are used to decorate the space effect, and the decoration function is as important as the lighting function.
The table lamp in the living room has gone far beyond the value of the table lamp itself, and it 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.
Desk lamps are not only used for reading and decoration. The latest technology is like a robot, which can move, dance, automatically adjust the light, play music, clock, video, touch and other functions, especially the ceramic desk lamp has collection value.
Classification of floor lamp control modes
1. Touch control
The principle of touching the desk lamp is to install an electronic touch ic inside, which forms a control loop with the electrode sheet at the touch of the desk lamp. When the human body touches the induction electrode plate, the touch signal generates a pulse signal through pulsating direct current, which is sent to the touch induction end, and then the touch induction end will send out a trigger pulse signal to control turning on the light; If you touch it again, the touch signal will generate a pulse signal through pulsating DC and send it to the touch sensing end. At this time, the touch sensor will stop sending out the trigger pulse signal, and when the alternating current crosses zero, the lamp will naturally go out. But sometimes it will light itself after power failure or voltage instability. If you touch paper or cloth and have excellent sensitivity to the received signal, you can control it.
2. Adjustable brightness
The working principle of the adjustable desk lamp consists of resistor R2, potentiometer RP 1 and capacitor C.
Circuit, by adjusting RP 1, the conduction angle of the triac V can be changed, thus changing the brightness of the bulb EL. The resistor R 1 is a current-limiting resistor. The charging speed of C is also related to the parallel circuit. When R 1 and RP2 are fixed, the shunt is determined by the resistance of the photoresistor RL. When the grid voltage rises, the lamp brightness increases, the RL resistance decreases, the shunt increases, the voltage across capacitor C slowly rises, the conduction angle of thyristor V decreases, the output voltage decreases, and the lamp brightness decreases. Conversely, when the grid voltage drops, RL resistance increases, shunt decreases, thyristor conduction angle increases, output voltage increases, and lamp brightness increases. In this way, the brightness of the lamp will automatically stabilize at the set value.
Which brand of floor lamp is good?
Kang Luyuan's 24V DC incandescent piano lamp is the first DC incandescent piano lamp in China, which is designed and manufactured in strict accordance with the national standard of Reading and Writing Table Lamp (GB/T9473-2008) in 2008. It was patented by China and invented by a doctor. It has no blue light, no stroboscopic light and no radiation. The color rendering index is as high as 100Ra, the color temperature is 2800k, and the flicker is zero.
The above are some good introductions of floor lamp brands. I believe everyone has a certain understanding of desk lamps and must be familiar with them. The choice of desk lamp is mainly based on our actual needs, and the role of desk lamp in family decoration can not be ignored. We must pay attention to the choice of desk lamp, which is a good desk lamp. Everyone must choose a better brand according to their own needs, hoping to help everyone.
