EL luminous films as electroluminescence, also known as field luminescence, the English translation of Electro Luminescent (referred EL), it is the light energy is converted to a form, but there is no heat in the conversion process will not heat, it is generally known <SPAN title="" closure_uid_4iqtj8="28293" gd="“冷光”。" ? cold.? hd="">"cold." EL power LED is green, safe, energy saving of a new type of high-tech products, is an advanced cold source.
It is the luminous powder placed between two electrodes consisting of flat. The sandwich structure for the upper and lower have an electrode, the electrode is a transparent conductive film (ITO film), the light from this side injection, the lower electrode as the back electrode, the main material for silver or carbon, light-emitting materials are mainly zinc sulfide (ZnS ), when the AC voltage is applied to two electrodes, the electric field makes the (ZnS) particles have pumped transition, resulting in a charge-discharge cycle of each LED, as it contains a different active agent, may issue a different color of light. EL brightness as the voltage between the electrodes, the change of frequency change, in general, with the voltage and frequency of increasing the brightness also increases.
Use of the technology to produce products in the light when out almost no heat, is a cold light. Therefore, when used in certain occasions does not allow generated heat radiation, such as the LCD backlight, is more appropriate. Life of up to 20,000 hours or more, with all the electronic machine to match the life of the product, not neon luminous crystal thin films by light-emitting life affect the normal operation of machine configuration, also reflects the high life in independently in many areas of the economy, but also in fear damage, even if divided into several small pieces, while retaining the original small piece of the electrode can still light on the normal, unlike the commonly used lighting. The minimal heat, to avoid the general lighting source fever led to the shortcomings of the aging products. Widely used in a variety of backlighting, signs advertising art, architecture car decoration, warning signs, lights, LED gifts, etc.
EL Features
1. Harmless - no ultraviolet light, without adverse effects on the human body.
2. Any shape - can produce various shapes according to user needs
3. Power consumption low - very low in the battery will light, the power consumption of milliwatts
4. Thin - the thinnest of up to 0.18mm the following
5. Flexible - can be in various forms of luminescence, can bend light to adapt to the shape or folding products.
6. Do not heat - electroluminescent film is a cold light source, at work and almost no temperature rise, lower temperature than fluorescent.
7. Light evenly, soft - its light is not flashing, will not make eye tension, fatigue.
8. Earthquake good - electroluminescent film different from other light-emitting devices, and its not easy to face the outside world due to the impact of the failure
9. Long life - EL is based on the life of the half-life (half brightness) to measure, usually the time for 3000-25000
