decorative gravels EL is an energy conversion device

Theory of Operation 

Works 

EL is an energy conversion device, cold light source for general working 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 decorative gravels  brightness, if the increase in frequency also increase the brightness, color and feel cold light blue. 

Luminescence lifetime 

Unlike traditional cold light source phenomenon will suddenly come to an end, but after a long period of use, the brightness of luminescence will gradually decline, voltage, frequency, temperature, and moisture are important factors that affect the luminescence lifetime. 

Luminescent brightness 

Luminescence brightness can be obtained via photometric measurements, so the brightness cold light source photometric calculations usually expressed in units, but the human eye is less likely to achieve such sensitivity, standards are usually visual sense and photometer comparison, there will be a certain degree of error. 

Luminescent power source 

Produce cold light source via a matching transformer inverter luminous paint design (DRIVER) to drive, and the drive voltage and frequency cold tablets, is in accordance with the size of the light sheet area, the use of the environment, life and other professional considerations conditions supporting the design and development of production processes. 

Weight and thickness of the luminescent film 

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

Flexural toughness cold tablets 

Another advantage of EL sheet is that it has good flexibility, typically more than 2cm radius bending is acceptable, the flexural toughness characteristics of the EL sheet also gives more different environments purposes. 

The sealed edges of cold tablets 

In the cold light emitting masters of weeks it is proposed should be glowing sands kept sealed appropriate width along at least a basic package should be 0.1cm, narrow luminescence lifetime package will make subtle changes.
