LED quvvat manbaining asl quvvat manbai uchta muhim turga ega: past kuchlanishli batareyalar, quyosh batareyalari va aloqa bozori elektr ta'minoti. Qaysi asl quvvat manbai qabul qilinishidan qat'i nazar, LED bilan qoniqish uchun quvvat o'zgarishining zaruriy sharti. Ushbu turdagi quvvatni o'zgartirish davri odatda LED qo'zg'alish davrini anglatadi. LED quyosh energiyasi bilan ta'minlash tizimida quyosh energiyasini saqlash uchun batareyalar yoki ultra-superkondansatkichlar kerak. Kechasi yoritilganda, batareyalar yoki superkondansatkichlar keyin LED qo'zg'aysan pallasini quvvatlantirish uchun kontaktlarning zanglashiga olib borish jarayoni orqali chiqariladi. Quyosh energiyasi va shamol energiyasi va LEDning birlashuvi LEDning bir yillik diqqatga sazovor joyidir. Bu qashshoqlik va uchinchi dunyoning chekka hududlariga yorug'lik olib keladi va ulug'vor yashil yorug'lik dunyoning har bir burchagini yoritsin. LED quvvat manbai va ularning asosiy harakat sxemasi dizayni 1. Past kuchlanishli doimiy quvvat manbaiga ega LFD drayveri sxemasi 1. Kirish kuchlanishi LED kuchlanishidan yuqori bo'lsa, kirish kuchlanishi LED yoki LED satrining kuchlanishidan yuqori bo'lsa Antihipertenziv regulyator. (1) Lineer regulyator chiziqli regulyator DC-DC antihipertenziv konvertordir. LED qo'zg'aysan davri tomonidan qabul qilingan chiziqli regulyatorlarning ko'pchiligi past kuchlanishli differentsial regulyatorlar (LDO). Kuchli tomonlari shundaki, indüktans komponentlariga ehtiyoj yo'q, kerakli komponentlar soni kichik, EMI bepushtligi paydo bo'ladi va o'z kuchlanishining pasayishi kuchdan ko'ra kuchni pasaytirish kuchidan past bo'ladi. Biroq, kalit tipidagi regulyator bilan solishtirganda, LDO ning quvvat yo'qotilishi hali ham nisbatan eski va samaradorlik pastroq. LDO 350mA yoki undan yuqori quvvatli LED simini ishlatganda, uni radiator bilan qo'shish kerak. (2) Kalit kuchlanish kuchlanishi (buk) stabilizatori bitta chipga xos bo'lgan ICning kalit tipidagi antihipertenziv regulyatoriga asoslangan. Ko'pgina antihipertenziv regulyatorlarni almashtirish chastotasi 1 MGts dan ortiq, bu tashqi komponentlarni juda kichik qiladi. Chiqish juda kichik, samaradorligi 90% dan ortiq. Biroq, bu turdagi konvertor kommutatsiya shovqinini keltirib chiqaradi va EMI muammosi mavjud. 1-rasmda Zetex ZXSC300 asosidagi 3WLED kuchaytiruvchi haydovchi sxemasi ko'rsatilgan. Bu erda RCS elektr uzatishni sezuvchi qarshilikdir. 6V kirish kuchlanishi ostida, joriy LED oqimi 5 pinli SOT23 qadoqlashni qabul qilish uchun 1.11A.ZXSC300 ga etadi. LED quvvat manbai va uning asosiy haydash sxemasi dizayni hozirda MOSFET (Q1) va antihipertenziv diyotni (D1) almashtirish uchun ko'plab antihipertenziv transformatorlar bitta chipli ICga ega. 2. Kirish kuchlanishi LED kuchlanishidan pastroq bo'lsa, kirish kuchlanishi LED yoki LED satrining umumiy musbat kuchlanish kuchlanishidan past bo'lsa, LED kuchlanish qo'zg'aysan pallasini oshirishi kerak. Quyidagi ikkita turdagi kuchaytirgich konvertorining ikki turi mavjud. (1) To'g'ridan-to'g'ri bosim konvertori Uyali telefonning buzilishi yoritilishida induktiv kuchlanish kuchlanishli LED drayverning sxemasi tez-tez ishlatiladi. Kalit tipidagi indüktans kuchaytirgich konvertori bir yoki bir nechta LED kompozitsiyasining LED chizig'i sifatida ishlatiladi va har bir LEDning oqimi tengdir. Agar LED chizig'ida LED yo'li bo'lsa, boshqa LEDlar o'chadi. 2-rasmda induktiv kuchlanishli LED qo'zg'alish davri ko'rsatilgan. LED chizig'i 8 Japan Asia Chemical Corporation kompaniyasining NSPW500BS tipidagi NSPW500BS oq nurli Ledli lampalaridan iborat. 4V kirish voltaji ostida har bir LEDning oqimi har bir LED uchun taxminan 25mA ni tashkil qiladi. LED quvvat manbai va uning asosiy haydash sxemasi dizayni asosan regulyator ICni kuchaytiradi va kommutatsiya trubkasi chipga o'rnatilgan. (2) Kalit kondansatkich (zaryad nasosi) kuchaytiruvchi konvertor kondansatör kuchlanish konvertorini, ya'ni zaryad pompasini o'zgartiradi. Zaryadlovchi nasosning maxsus IC 1 yoki ikkitasiga ulangan o'rnatilgan kalitga ega 1 μF ning zaryadlovchi kondensatori. Lar bor 1 ×, 1.5 ×2 ×So'nggi yillarda u 1 ko'rsatdi.33 ×(4/3 marta) va 4 ×model. Chiqish kuchlanishi kirish kuchlanishiga yaqin bo'lganda, zaryadlovchi nasos kuchlanishni oshirishga hojat yo'q, ya'ni da 1 ×Model. Bosim kerak bo'lganda, 1 ga o'ting.5 ×Yoki boshqa narsalar. Zaryadlash nasosining sxemasi LED qatorini yoki faqat bitta LEDni boshqarishi mumkin.
