LED電路結構:何謂LED?| 電子小百科 - Electronics Trivia - ROHM
當電流沿LED正向流動時,正極和負極間產生的電壓稱為正向電壓(VF)。 單位為V(伏特)。 資料表等資料中刊登了相對於電流的正向電壓的特性曲線圖<正向電流(IF)-正向電壓(VF)特性>。 在實際探討LED照明電路時,這個特性是最為重要的考慮項目。 正向電流(IF)-正向電壓(VF)特性隨LED元件的材料、尺寸以及發光顏色的不同而不同。 而且隨環境溫度變化。 此外,還具有半導體特有的特徵值分佈,即所謂的偏差。 當LED恒流驅動時,正向電壓(VF)的 …
Light Emitting Diode or the LED Tutorial - Basic Electronics Tutorials ...
Like conventional PN junction diodes, light emitting diodes are current-dependent devices with its forward voltage drop V F, depending on the semiconductor compound (its light colour) and on the forward biased LED current. Most common LED’s require a forward operating voltage of between approximately 1.2 to 3.6 volts with a forward current ...
LED基礎篇:12個LED重要性能指標 - LEDinside

LED circuit - Wikipedia
In electronics, an LED circuit or LED driver is an electrical circuit used to power a light-emitting diode (LED). The circuit must provide sufficient current to light the LED at the required brightness, but must limit the current to prevent damaging the LED.
Light-emitting diode - Wikipedia
LEDs are transducers of electricity into light. They operate in reverse of photodiodes, which convert light into electricity. The first LED was created by Soviet inventor Oleg Losev [9] in 1927, but electroluminescence was already known for 20 …
