The life of EL brightness
Cold light source is not as sudden demise of traditional light sources have the situation, but after a long period of use, will gradually decrease the brightness of luminescence; voltage, frequency, temperature, humidity are all important factors affect the luminescence lifetime.
General EL: 150cd/m2, halflife: 2000 hrs lifetime: 8000 hrs @ 50 cd/m2 60R.H.
Height EL: 300cd/m2, halflife: 2000 hrs lifetime: 8000 hrs @ 100 cd/m2 60R.H.
EL, weight, thickness and flexural toughness
Light can be tortuous, often more than 3cm radius of bending is acceptable, can be any shape, as is generally cold piece of paper the main features of the average parameters are as follows; but for some special orders, change its parameters can be followed
Average weight: 0.1 ~ 0.2g/cm2
Average thickness: 0.3mm ~ 0.7mm
Seal edges EL
Masters of the week in the cold light emitting at least 0.1cm along the edge seal, a narrow edge seal will produce subtle changes in luminescence lifetime, it is proposed should maintain the basic side sealed the appropriate width.
EL color
EL luminous film background basic standards are: green, blue, green, blue, white foundation. In addition to the basic color, but in a certain range, through special dyes and ink color through the combination of film applications, it can be bright dazzling effect.
EL size
Size of the largest production of cold tablets, single area within the 110 * 220CM, is made can be accepted.
EL power source - Driver
The production of cold light source, is supporting the design of the transformer through a variable frequency drive (INVERTER) to drive, and drive voltage and frequency of cold tablets, is the size of the area in accordance with rays, emitting area, the use of the environment, life and other considerations conditions for supporting the design and production of professional production.
In the cold light slice of the power supply drive mode, we can design projects in accordance with customer demand,
For example: 1. You can use batteries DC1.5V, 3V, 6V, 9V, 12V power supply, to promote the design of cold-chip LED driver
2. Can be used automobiles, motorcycles DC12V, 24V power supply, to promote the design of cold-chip LED driver
3. You can use indoor power supply AC110V ~ 230V power supply, to design the drive to promote the cold light emitting chip

EL's performance:
1. Low power consumption: even when the voltage is very low light is easy to implement, the power consumption of milliwatts, when efficiency becomes a factor, the electroluminescent film to be an ideal choice.
2. Compact size: the thinnest of up to 0.2mm, can be used to light a small space as possible.
3. Resistant to bending: it can bend light to adapt to the shape of products, lighting products more than any of its flexibility, a certain degree of flexibility in the rich, complex shapes according to customer requirements of any crop, which products to apply the EL assembly with supporting applications to favorable conditions.
4. No heat, electroluminescent film is a cold light source, at work and almost no temperature rise, operating temperature is much lower than the fluorescent lamps. So it completely avoids the accumulation of heat resulting in a series of problems (fire safety).
5. Luminous good: light, even, soft, high luminous intensity, electroluminescent film is different from the traditional point or line emission mechanism, but a uniform light emitting surface of the whole body, not even look directly at the light flashes and will not glare, will not make eye tension, fatigue, there is no Bansi harmful to human body, without radiation.
6. Earthquake good: light-emitting devices with other different, its not easy to face the outside world because of the severe impact of the failure, in the harsh environment applications.
7. Long life: EL is based on the life of the half-life (half brightness) to measure, usually the time of 5000-20000 hours, affecting the life of the main reasons is the voltage, frequency, temperature and humidity.
EL cold light film features
1. Super-power, short wavelength light, no radiation, particularly at night and bright, striking, suspicious eyes of passers-poly
2. Poly rotation is strong, as the distance can be far, that is attractive
3. Thin, lightweight, easy to make and construction, project cost savings, manpower, efficiency, provide students
4. The devices easy, the spread of ability and high mobility ad
5. A novel of sexual and attractive, easy to achieve the desired effect of advertising or
6. Cold light film tailor-made as per customer requirements, the production of different sizes, shapes of cold tablets
7. Cold tablets in addition to constant light and flashing functions, can also be made up slowly fades or more paragraphs flashing, voice, body sensor model.
Based on the above features, advertising industry from the following applications, and to think about the cold light of where the market:
1. Need to strong advertising (including: Fast, permeability and weather) bring the goods,
For example: tobacco, alcohol, drinks, credit cards ... ... the billboard signs advertising sales or other
2. To save energy and enhance the security of the areas (can replace traditional neon tubes)
3. Can be customized according to customer requirements flashing way to make a significant advertising effect
