Ultraviyole chiroqdan foydalanish

U ultrabinafsha sterilizatsiya, qo'zg'alish floresansi (flüoresans mikroskop, banknotni tekshirish), zararkunandalarni tutish va o'ldirish, chop etish va boshqalar uchun ishlatilishi mumkin.

Har xil shakl va oʻlchamli, burchak va egilishlar, qirralar va boʻrtmalarga ega boʻlgan uch oʻlchovli qismlar-qoralanganda yorugʻlik barcha yuzalarga yoyilishi va yetarli energiya boʻlishi kerak. Umumiy lampalar va chiroqlar chiroq naychalari va reflektorlardan iborat. Reflektorlar yorug'lik nurlarini yig'ish va ularni ob'ektlarga chiqarish uchun ishlatiladi. Reflektorlar odatda oval yoki parabolikdir. Elliptik reflektordan foydalanilganda, chiroq trubkasi ellipsning birinchi fokusiga joylashtiriladi va yorug'lik tor yuqori nurlanish nurini hosil qilish uchun ikkinchi fokusga qaratiladi.

However, due to the divergence of light, the irradiance decreases rapidly after deviating from this point. Using parabolic lampshade, parallel ultraviolet beams can be obtained in a wide range, but the irradiance is low and shadows can be added on three-dimensional objects. Many three-dimensional objects in industry need to cure "optical thick" coating when painting, which is a coating with high UV absorption. However, the energy density of UV light will decrease rapidly when passing through the coating, which is very unfavorable to curing. In order to ensure sufficient curing, the bottom of the coating also needs sufficient light. Moreover, the thick coating contains a lot of pigments and additives, which is not conducive to light transmission. Complete curing can only be achieved by using high irradiance ultraviolet light. When painting a flat base, an elliptical reflector can be used to focus the highest radiation area (i.e. focus) on the coating. However, it is much more difficult to realize the solidification of three-dimensional objects.

Yilni modulli yoritish tizimi ob'ektlarning konturini kuzatishi yoki muayyan hududlarni yoritishi mumkin. Mikroto'lqinli quvvat chiroqining elliptik konkavini to'g'rilash yorug'lik markazini o'zgartirishi, diqqatni chiroq yuzasidan uzoqroq qilish va fokus yuzasini kengaytirishi mumkin. Garchi bu nurlanishning eng yuqori qiymatini pasaytirsa ham, yorug'lik intensivligini bir xil qilish va chiroqdan uzoqroqda etarli darajada nurlanishni olish mumkin. Shu bilan birga, u yorug'likni to'plash va tarqatishning afzalliklarini saqlab qoladi va soyalar paydo bo'lishini kamaytiradi. Taqqoslash uchun 1-jadvaldagi natijalarga qarang. 1-jadval - Chiroq va ob'ekt o'rtasidagi santimetrga 240 vatt (fut boshiga 600 vatt) bo'lgan lampalar uchun kvadrat santimetr uchun vattdagi eng yuqori nurlanishni taqqoslash: reflektor turi.
