Yayoboye TV 55 cm yubwenge TV yuzuye beze

Nigute wakemura ikibazo cyo gukwirakwiza ubushyuhe bwo murugo hejuru-ibisobanuro byerekana?
Ikibazo kinini murugo-ibisobanuro bihanitse byerekana muri iki gihe ni ugukwirakwiza ubushyuhe.Imbere mu bisobanuro bihanitse byerekana imbaraga nyinshi, kandi igice kinini cyingufu zitakaza ubushyuhe.Umuriro urashobora gutera ibibazo byinshi.None nigute wakemura ikibazo cyo gukwirakwiza ubushyuhe bwimbere murwego rwo hejuru?Imbere murwego rwo hejuru-rwerekana uruganda - Ibikoresho bishya bya Optoelectronics byerekana muri make ingingo zikurikira:

1. Ubunini: Ninini yerekana imbere murwego rwo hejuru, niko ishoramari ryibikoresho bitanga umurongo.Ubwiyongere bwubunini bwimbere-busobanura ibyerekanwe biroroshye cyane, nkibice byubaka.Gukemura nabyo biroroshye kubigeraho ukurikije ibyo abakoresha bakeneye.

2. Ibara ryuzuye: amatara, amatara ya neon, nibindi byose ni monochrome, kandi LED ibona guhuza RGB amabara atatu yibanze.

3. Kwizerwa kwinshi: LED ni itara rikomeye hamwe nubwizerwe buhebuje, bitandukanye na neon tubes, amatara nandi nkayo ​​akenera imiyoboro ya vacuum.

4. Kuramba kuramba: Ubuzima bwa theoretique ya LED chip irashobora kugera kumasaha 100.000, kandi igihe cyo kubaho ni amasaha arenga 30.000.

5. Ibidukikije byangiza ibidukikije: LED yerekana ubwayo nigicuruzwa kibika ingufu kandi kidafite umwanda.

Noneho ubushyuhe bwimbere murwego rwo hejuru busobanura buturuka he?Kuva kumashanyarazi kugeza kumatara ya LED, kugeza kuri LED, kugeza kubishobora guhinduka, igice cyo gushyushya kirimo amatara ya LED, abashoferi ba LED, ninsinga za LED.Reka dufate urugero rwa 5V amashanyarazi:

1. LED ikora neza igera kuri 20%, kandi ubushyuhe bwa LED bugizwe na 50% yubushyuhe bwose

2. Igenzura noguhuza insinga bingana na 5% yumubare wuzuye wa calorificateur

3. Kugabanuka kwa voltage yo gutwara: 1.8V (G / B) cyangwa 3V (R) igabanuka rya voltage, ubushyuhe bwigice cyo gutwara bingana na 45% yubushyuhe bwose.

Ubushyuhe bwo kubyara murugo-busobanura cyane amatara ya LED akeneye kunoza imikorere ya LED.Hano hari ibyumba byinshi byo kunonosora ubushyuhe bwigice cyo gutwara, nicyo gice dutegereje kunoza.
