Quick Detail:

Product Features

In need of special light sources (eg: no shadows, no dizzying, brightness uniformity and neon effect ......), in with the environment needs (eg: a narrow space, complex shapes, temperature and power consumption constraints, vibration under the environment ......), the illusion is impossible to make up the traditional cold light source.

In addition, for printed mark, instructions, election propaganda, body decoration and interior design, photo or text on backlit transparent advertising material, EL cold light is the best light materials

EL Specifications Feature Description:

?1. Cool Works is a converted electrical energy, cold light source general operating voltage and frequency operating voltage can be adjusted after AC40V ~ AC220V, while the operating frequency can be 50 Hz to 4000 Hz, increasing the voltage will increase luminescence brightness, if the increase in frequency can increase the brightness, color and feel cold light blue.

2. EL cold light of life is not like traditional light sources have the sudden demise of the phenomenon, but after a long period of use, the brightness will gradually decreasing cold, voltage, frequency, temperature, moisture, cold light of life are affected key factor

3. The luminescent brightness of luminescent brightness can be obtained by photometric measurement, the luminance of the luminescent light source is usually expressed in units of photometric calculation, but the human eye is less easy to achieve such sensitivity, visual sense and generally photometer the standard of comparison, there will be a certain degree of error.

4. EL cold light source to produce power source, via a matching transformer inverter design (DRIVER) to drive, and the drive voltage and frequency of cold tablets, is consideration of the size of the area in accordance with rays, use of the environment, life, etc. conditions for supporting the design and development and production of professional production.

5. Cold light weight and thickness of cold tablets have a very attractive main condition is that the weight of its weight and thickness, cold tablets is 0.1 grams per square centimeter, and the thickness is 0.2mm ~ 0.5mm, the special requirements for some orders , weight and thickness of the luminescent film will be followed by change.

6. Another advantage of cold tablets bending toughness cold tablets is that it has good flexibility, usually 2cm above bending radius is acceptable, this bending toughness characteristics, but also gives a cold tablets have more different environments purposes.

7. The sealed edges of cold tablets in the week along the famous Flashing should be at least 0.1cm package, narrow luminescence lifetime package would produce subtle changes, it is proposed should be kept sealed properly basic width.

8. EL cold light emitting principle principle glowing EL sheet is the material layer converts electrical energy into light
