LED Characteristic
- Jul 31, 2017 -

Compared with the incandescent bulbs and neonthe characteristics of the light-emitting diode is

the working voltage is very low (some only a few feet); work current is very small (some only zero a few cents to light); impact and seismic performance Good, high reliability, long life; through the modulation of the current strength can be easily modulated light intensity. 

Because of these characteristics

light-emitting diodes are used as light sources in some optoelectronic control devices and are used as signal displays in many electronic devices. 

The tube is made into stripes

and seven strips of LED are used to form 7-segment semiconductor digital tube. Each digital tube can display 0 ~ 9,10 Arabic numerals and A, B, C, D, E , F and other letters (must be case-sensitive).
