Electroluminescent
1. Electroluminescent Wire Overview
Electroluminescent (EL) refers to the physical phenomenon of exciting materials to produce light radiation through electric fields. The principle is: applying voltage to the two poles to form an electric field, exciting electrons to hit the luminescent center, causing electron transition, recombination, and emission. This technology does not require traditional light sources and directly converts electrical energy into light energy.
2. What is Electroluminescent Wire Used for?
Display Technology: such as flexible screens, OLED (organic electroluminescent devices), etc., with high luminous efficiency, wide viewing angle, fast response, and bendable characteristics.
Lighting Equipment: used in scenes such as backlight sources and indicator lights.
Test Equipment: String EL test power supply can simulate actual working conditions and detect the electroluminescent performance of components.
3. What are the Key Component Types of Electroluminescent Wire?
Organic Electroluminescent: It is composed of an anode, a light-emitting layer, an electron transport layer, and a cathode, and uses electron transport materials containing cyano and aromatic rings to improve performance.
Traditional Electroluminescent: such as electroluminescent screens based on inorganic materials, commonly found in early display devices.
4. What are the Technical Advantages of Electroluminescent Wire?
High efficiency and energy saving: high luminous efficiency and long device life.
Flexible design: supports flexible, transparent, and ultra-thin forms.
Cost controllable: optimization of materials and manufacturing processes reduces production costs.
5. Testing and Verification of Electroluminescent Wire
EL testing requires the use of dedicated power supply equipment (such as string EL test power supply), through multi-channel output, programmable control, and automated data acquisition to ensure component performance and reliability.
6. Electroluminescent Wire FAQs
1) What is the power supply requirement for Electroluminescent Wire?
EL wire usually requires high-voltage AC power (such as 80-150V, frequency 400-2000Hz), which can be converted into the required parameters by a dedicated inverter. The power frequency and voltage directly affect the brightness and color stability.
2) What is the service life of Electroluminescent Wire?
The typical life is 3000-5000 hours, and the actual life is affected by the following factors:
Frequency of use (continuous operation will shorten the life);
Ambient temperature (high temperature accelerates aging, low temperature may reduce brightness).
3) How to maintain and use an Electroluminescent Wire?
Avoid repeated bending or mechanical shock to prevent the internal conductor from breaking;
The recommended operating temperature is between -20°C and 60°C;
When storing for a long time, the power supply must be disconnected and kept dry.
4) How to choose the color of Electroluminescent Wire?
By adjusting the composition of the phosphorescent material coating, a variety of colors such as blue, green, and white can be produced, but it should be noted that the luminous efficiency and service life of different colors may vary.
