The Characteristics of LED illuminationÂ
Fifty years ago,the huminality had already known the basic
knowledge of semiconductor material can produce light，The first
commercial diode produced in ***0.LED is short for light emitting
diode(LED),its basic structure is an electroluminescent
semiconductor material，placed on the a stand with
down-lead，and then sealed with epoxy resin around in order to
protect internal batteries，so the aseismatic capability of LED
is good。Â
The advantages of LED illuminationÂ
1. Security：LED is supplied by low-voltage power，so it is
safer than supplied by high voltage power,it is particularly
applicable to public.Â
2. Economy:compared with the incandescence lamp the energy
consumption reduces *0% 3. Applicability:convenient apply,each
unit of LED snippet is **5mm square,it can be preparedÂ
into various shaped devices,and suitable for the inconstant
environment. 4. Stability:it can work *****0 hours,the light
decay is *0 percent of the initial.Â
5. Response time:fincandescence lamps base on millisecond,the LED
base on nanosecond. 6. Environment protection:no harmful metal
mercury.Â
7. Color:changing the electric can change the color,the
light_emitting diode easily adjust theÂ
energy band structure and the band gap through chemical
modification,adjustment of the energy band structure and the band
gap and achieve multicolor luminescence.For example,with small
current at the LED is red,but with the current increase,it will
turn into orange,yellow.and green finally.Â
8. Life-span:the expectancy of LED is more than incandescence
lamp,it is more than ten times asÂ
an ordinary incandescence lamp.Â
