Led diffuzorning rivojlanish bosqichi va optik o'ziga xos qiymatlari batafsil tushuntirilgan

Led diffuzorning rivojlanish bosqichi va optik xarakteristik qiymatini batafsil bilasizmi?

1. Led diffuziya plitasining rivojlanish bosqichi:

1. Yorug'lik manbasining soyasini yaxshilash va xarajat ko'rsatkichlarini olish uchun diffuziya effektiga ega zarrachalarni qo'shing;

2. Diffuziya effektini yaxshilash, tashqi ko'rinish ish faoliyatini yaxshilash va yorug'lik o'tkazuvchanligini yaxshilash;

3. Optik xususiyatlarni optimallashtirish, UV qarshiligini yaxshilash, zarba qarshiligini yaxshilash, yorug'lik samaradorligini oshirish va yorug'likni taqsimlash talablariga javob berish;

4. Yuqori haroratga chidamlilik, yuqori yorug'lik o'tkazuvchanligini saqlab qolish sharti bilan mahsulotning tuman qiymati yaxshilanadi, bu yaqin masofadagi nurlanish muhitida foydalanish uchun mos keladi.

2. Led diffuzorning optik xos qiymatlari:

Generally, for the quality control of optical properties of transparent and translucent plastics such as plate, sheet, film, and tube, the indicators such as transmittance and haze are mainly evaluated by testing. Our country was proposed by the former Ministry of Chemical Industry of the People's Republic of my country, drafted by the former Ministry of Chemical Industry Chenguang Chemical Research Institute and other units, and issued by the State Administration of Standards. ". which are defined as follows:

  1. Light transmittance - the ratio of the luminous flux (Luminous Flux) passing through the sample to the luminous flux hitting the sample, expressed as a percentage.

  2. Haze—the ratio of the scattered luminous flux deviating from the incident light direction through the sample to the transmitted luminous flux, expressed as a percentage (for this method, only the scattered luminous flux deviating from the incident light direction by more than 2.5 degrees is used to calculate the haze) . The cloudy or cloudy appearance of the interior or surface of a transparent or translucent material due to light scattering. Expressed as a percentage of the ratio of the scattered luminous flux to the luminous flux transmitted through the material. It is an important parameter for the optical transparency of transparent or translucent materials.

3. Sinishi indeksi-----sizning o'tkazuvchanligingiz yoki tumaningiz qanday o'zgarishidan qat'iy nazar, u allaqachon optikasini sifat (zichlik) bo'yicha aniqlagan. Sinishi indeksi qanchalik baland bo'lsa, o'tkazuvchanlik shunchalik past bo'ladi va qalinligi bilan hech qanday aloqasi yo'q. Yorug'lik o'tkazuvchanligi ham, tuman ham materiallarning shaffofligini o'lchash uchun ko'rsatkichlar bo'lib, ular diffuzerlarga qo'llanilishi shart emas. Umuman olganda, yorug'lik o'tkazuvchanligi va tuman o'rtasida teskari bog'liqlik mavjud va aksincha.

Yuqorida aytilganlar faqat shaffof materiallarning ta'rifidir, chunki 1980-yillarda mahalliy shaffof plitalar etarli darajada shaffof bo'lmagan va xorijiy me'yorlar keltirilgan. Axir, 1981 yilda, 2014 yilga kelib, rasmiy spetsifikatsiya yo'q bo'lsa ham, diffuzer plitalarining ta'rifi uchun aniq spetsifikatsiyalar yaratgan hech qanday mamlakat yoki mintaqa yo'q edi. Bu atama dastlab toʻgʻridan-toʻgʻri{3}}yoritilgan orqa yorugʻlik modulidan kelib chiqqan, shuning uchun diffuzor plitasini shaffof plitaning spetsifikatsiyasiga murojaat qilish orqali toʻliq tushuntirib boʻlmaydi, shuningdek, bu mening mamlakatim tomonidan ishlab chiqilgan standart emas, shuning uchun u qoʻllanilmasligi mumkin. . Qattiq yorug'lik-da, LED yorug'lik manbai va LED yoritgichning rivojlanishi bilan uni qo'llash texnik qiyinchiliklarni keltirib chiqaradi. Mahalliy ishlab chiqaruvchilarning hech biri optik muhandislik bo'yicha mutaxassislarga ega emasligi sababli, ular hali ham qayta ishlash bosqichida.
