Se os led''s tiverem uma tensão(volts) de funcionamento diferente, apenas o led de menor tensão acenderá e possivelmente ficará destruído. Se os leds forem idênticos, podem ligar-se em paralelo, raramente este tipo de ligação oferece benefícios, é preferível e aconselhável usar cada um dos leds com a sua resistência limitadora ou
Brightness: LED''s are four times brighter than halogen lights. With LED headlights, consider driving in the dark a thing of the past. Efficiency: LED''s use less energy and last longer than halogens.When you get LED''s, those lights are with you for the long haul. The It Factor: LED''s offer a sleeker, more modern aesthetic than halogens.
太阳能光伏发电技术能与LED 照明完美无缺结合的关键在于两者同为直流电、电压低且能互相匹配。因此两者的结合不需要将太阳能电池产生的直流电转化为交流电,因此大大提高了整个照明系统的效率。同时,借助于并网技术或利用蓄电池充放能量
