How to say "led" in Japanese
Choosing the right word
- ＬＥＤエル・イー・ディーnounThe 'LED' sense: a diode that emits light when current flows through it. This is simply the English acronym, and a less common way to name the part when talking about electronics.
- 発光ダイオードはっこうダイオードnounThe same device, named in full: 'light emission' plus 'diode'. Also a less common choice; use it when you want the spelled-out technical term, for example in an explanation or a specification.
Both words cover only the noun 'LED', the light-emitting diode — not 'led', past tense of 'lead'. ＬＥＤ uses the acronym as-is, while 「発光ダイオード」 spells the term out; in meaning the two are interchangeable.
