Yorug'lik diodining qarshiligi sovuq bilim

2022-12-21

Tianhui

Men qarshilik qo'shishim kerakmi? Kuchlanishsiz qarshiliksiz nima bo'ladi? Ha, yorug'lik chiqaradigan diyot foydalanishga qarshilik bilan qo'shilishi kerak. Yorug'lik chiqaradigan diyot to'g'ridan-to'g'ri ma'lum bir kuchlanishda bo'lishi mumkin emas. Oqim qarshiligi cheklangan bo'lishi kerak. Aks holda. Nima uchun yorug'lik chiqaradigan diyot to'g'ridan-to'g'ri kuchlanishning har ikki uchiga to'g'ridan-to'g'ri ulanishi mumkin bo'lmagan kuchlanish diodlariga ulana olmaydi, asosan ikkita sababga ko'ra yuzaga keladi: 1) musbat kuchlanish pasayishi mos kelmaydi; 2) hozirgi o'zgarishlar katta. Sababi quyida. Yorug'lik chiqaradigan diyotning ijobiy bosimining pasayishi boshqacha. Oddiy ishlaganda, yorug'lik chiqaradigan diyot VF bosimining ijobiy pasayishiga ega bo'ladi. VF ma'lum bir qiymat emas, balki qamrovdir. Misol sifatida qizil yorug'lik chiqaradigan diodani oladigan bo'lsak, VF diapazoni (1,7-2,2) V ni tashkil qiladi va har safar yorug'lik diyotining xarakteristikasining mustahkamligi yaxshi emas va u biroz farq qiladi, shuning uchun uni topish qiyin. barcha diodlar uchun mos bo'lgan kuchlanish. 2. Yorug'lik chiqaradigan diyotning to'g'ri yo'li. Yorug'lik chiqaradigan diyot odatda ikkita haydash usuliga ega. Birinchi usul - kuchlanishdagi oqim -cheklangan qarshilik mag'lubiyati bilan ulanish; ikkinchi usul - haydash uchun doimiy oqim manbasidan foydalanish. Doimiy kuchlanish haydovchi. Oqimning haddan tashqari katta bo'lishiga yo'l qo'ymaslik uchun yorug'lik chiqaradigan diod yonib ketadi va yorug'lik chiqaradigan diyot va oqimni cheklovchi qarshilik oqim bo'lishi kerak. Qarshilikning qiymati quyidagi formulalar bilan yakunlanadi: R = (V-Vf) / i. Ularning orasida VF - emitent diodning to'g'ridan-to'g'ri kuchlanishi va i - men o'tkazmoqchi bo'lgan oqim. Misol tariqasida qizil yorug'lik chiqaradigan diyotni oladigan bo'lsak, oldingi kuchlanish pasayishi diapazoni VF (1,7-2,2) V va ish oqimi 2-25 mA. Agar siz uni formulaga keltirsangiz. Ushbu haydash usuli odatda LEDlar soni kichik bo'lgan hollarda qo'llaniladi. Agar u quvvat ko'rsatkichi va signal ko'rsatkichi yorug'lik davri sifatida ishlatilsa, haydash diodining soni katta bo'lsa, doimiy oqim manbai drayverini ishlatishni ko'rib chiqishingiz mumkin. Hengliu manbai uy yoritish sanoatida keng qo'llaniladi. Barcha LEDlar ketma-ket ulanganligi sababli, bitta LED shikastlangan ekan, barcha LEDlar yorqin emas. 3. Ikki haydash usulini taqqoslash, oqim cheklovchi qarshilik usuli, asosan, LED chiroq boncuklarining soni nisbatan kichik bo'lgan hollarda qo'llaniladi. Afzallik shundan iboratki, sxema oddiy va kamchilik - yorug'lik chiqaradigan diyotning ijobiy bosimini pasaytirish mos kelmaydi, shuning uchun ko'p foydalanishning yorqinligi boshqacha. Hengliu manbasining haydash usuli har bir emissiya diodining yorqinligi asosan bir xil bo'lishini ta'minlashi mumkin, ammo alohida LED chiroq boncuklarining shikastlanishi barcha LED chiroq boncuklarining ishlashiga ta'sir qiladi. Xulosa qilib aytingki, yorug'lik chiqaradigan diodlarni to'g'ridan-to'g'ri elektr ta'minotida ishlatish mumkin emas.

Unveiling The Power Of UV LED Modules: A Breakthrough In Lighting Technology

How to choose UV LED Module For Your Needs

UV LED Modules have been in the market for many years and are used by businesses for curing, sterilizing, and disinfection. These radiation sources can be UV-A, UV-B, or UV-C. Different ultraviolet radiation modules perform differently.

Exploring The Efficiency And Versatility Of UV LED Modules In Various Industries

Introducing Seoul Viosys LED Modules: Reshaping the World of UV LED Technology

In a time characterized by advancements and growing concerns, for the environment the importance of ultraviolet (UV) light emitting diode (LED) technology cannot be overstated. UV LEDs find applications in fields such as water purification, sterilization and medical equipment.

What are the advantages of UV Disinfection?

Have you ever thought about the tiny microbes hidden from the naked eye that can wreak havoc on our health? From harmful viruses and bacteria to mold and allergens, these microorganisms can threaten our well-being. Fortunately, various methods of disinfection can help us eliminate these unwanted guests. One of the most effective and eco-friendly options is UV disinfection.

UVC LED Application Trend: UV Sterilization Water Bottle

Did you know that, as per a recent study, the average water bottle can harbor up to 300,000 colony-forming units of bacteria per square centimeter? That's more than the average toilet seat! With concerns about waterborne illnesses and the spread of germs at an all-time high, it's no wonder that UV sterilization technology has become a hot trend in the water bottle industry.

Does Ultraviolet Light Directly Irradiate The Human Body For Sterilization?

Ultraviolet (UV) is electromagnetic radiation that falls within the light spectrum between visible light and x-rays. UV LED diode is divided into three main categories: UVA, UVB, and UVC. UVC light, which has the shortest wavelength and highest energy, is most commonly used for sterilization because it can kill or inactivate many microorganisms, including bacteria, viruses, and fungi.

The Impact of UV Led on the Environment

UV LED technology has been making waves in the printing and other industries for its efficiency and effectiveness, but did you know that it also significantly impacts the environment? This cutting-edge technology improves quality, increases productivity, reduces energy consumption, and lowers greenhouse gas emissions. This article will discuss the environmental benefits of UV LED diode and how it is aiding to pave the way for a more tolerable future.

Key Applications of UV LED Curing in The Field of Microelectronics

UV LED curing is a process that uses ultraviolet (UV) light-emitting diodes (LEDs) to cure or dry adhesives, coatings, inks, and other materials. The process involves exposing the material to UV light, which causes a chemical reaction that results in the material hardening or curing. UV LED curing is a faster and more efficient process than traditional curing methods, such as thermal curing or air drying.

What Causes The white LED chip to Die?

Many manufacturers merely employ cheap and inferior materials to lower the price of lamps in order to entice clients. The rate of quality complaints about WHITE LED panel lights has risen in the last two years due to this. The panel lights' surface yellowing is one of them, and it's really bad. We'll talk about the causes of why white white LED chip die. Without further ado, let's dive right in.
