Everything You Need To Know About LED Lighting
2.LED stands for light-emitting diode.
A diode is an electrical device or component with two electrodes (an anode and a cathode) through which electricity flows - characteristically in only one direction (in through the anode and out through the cathode). Diodes are generally made from semi-conductive materials such as silicon or selenium - substances that conduct electricity in some circumstances and not in others (e.g. at certain voltages, current levels, or light intensities).
2.It`s really simple actually, and very cheap to produce, which is why there was so much excitement when LED lights were first invented!
When a light-emitting diode (LED) has a voltage source connected with the positive side on the anode and the negative side on the cathode, current will flow (and light will be emitted, a condition known as forward bias). If the positive and negative ends of the voltage source were inversely connected (positive to the cathode and negative to the anode), current would not flow (a condition known as reverse bias). Forward bias allows current to flow through the LED and in so doing, emits light. Reverse bias prevents current from flowing through the LED (at least up until a certain point where it is unable to keep the current at bay - known as the peak inverse voltage - a point that if reached, will irreversibly damage the device).

1. Indoor environment If the working environment of the indoor equipment is not too good, the dust can easily enter the main ink cartridge and then the secondary ink cartridge, thereby entering the nozzle, affecting the printing effect of the nozzle and shortening the service life of the nozzle.
2. The nozzle part on the surface of the operating nozzle cannot be rubbed against any object, and the fine hair is easy to hang on the surface of the nozzle. Causes plugging and dripping, which affects the coding effect. Therefore, it is very important to strictly operate the equipment.
3, auxiliary accessories Each of the accessories on the machine has its purpose, do not arbitrarily remove. Like the main ink cartridge, sub-tank, filter, etc. 4, the quality of ink and ink directly affects the quality of the screen, the nozzle. Zui is good to use the ink recommended by the equipment manufacturer, because these inks are subjected to strict, long-term testing, and the equipment has a certain guarantee for the nozzle. Do not add anything to the ink at will.
5. Maintenance of the printer must be cleaned before the power is turned off, and the nozzle should be placed on the nozzle cover with moisturizing sponge pad. This can ensure the condition of the nozzle and the quality of the coding, and also extend the nozzle to a certain extent. The service life.
LEDs are a simple invention with huge potential to change the lighting industry for the better. Don`t know much about them? Here are three big things you need to know to get your feet under you:
1.What Does LED Stand For?
2.A light-emitting diode is a semiconductor device that emits visible light when an electrical current passes through it. It is essentially the opposite of a photo-voltaic cell (a device that converts visible light into electrical current).
Did You Know? There is a similar device to an LED called an IRED (Infrared Emitting Diode). Instead of visible light, IRED devices emit IR energy when electrical current is run through them.
1.How Do LED Lights Work?
The p-type and n-type materials are created by introducing the original material to atoms of another element. These new atoms replace some of the previously existing atoms and in so doing, alter the physical and chemical structure. The p-type materials are created using elements (such as boron) that have less valence electrons than the intrinsic material (oftentimes silicon). The n-type materials are created using elements (such as phosphorus) that have more valence electrons that the intrinsic material (oftentimes silicon). The net effect is the creation of a p-n junction with interesting and useful properties for electronic applications. What those properties are exactly depends mostly on the external voltage applied to the circuit (if any) and the direction of current (i.e. which side, the p-type or the n-type, is connected to the positive terminal and which is connected to the negative terminal).

Introduction to the daily maintenance of the printer
First, the maintenance nozzle of the nozzle is one of the important parts of the inkjet printer, and it is also one of the delicate components of Zui. The use of the nozzle is important in maintenance and maintenance. The quality of maintenance and maintenance directly determines the use effect and service life of the nozzle. How to make your equipment bring more profits, this is a problem that everyone is considering. Obviously, extending the life of the nozzle is one of the means to reduce costs. The methods for extending the life of the nozzle are listed below:
