LED chiroq lümeni yo'nalishli yorug'lik manbasi tarkibini almashish
Yuqorida aytib o'tilganidek, LED yoritgichlar asosan yo'nalishli yorug'likdir. Koʻp yoʻnalishli LED lampalar mavjud boʻlsa-da, ular yoʻqolgan yorugʻlikni toʻldirish uchun moʻljallangan. Boshqacha qilib aytadigan bo'lsak, yorug'lik muhandislari yo'nalishsiz yoritishni ta'minlash va yorug'likning haddan tashqari yo'qotilishining oldini olish uchun-yo'nalishsiz yorug'likni ta'minlash uchun LED chipini turli joylarga joylashtiradigan armatura yoki lampochkani loyihalashtiradi.

The LED chip itself provides a directional illumination. Conventional light sources such as metal halides, high pressure sodium, fluorescent lamps and incandescent lamps are omnidirectional. That means they glow in all directions. As a result, they work well as a universal light source for the home. However, for specialized commercial and industrial environments such as warehouses, factories, and other commercial facilities, they need reflectors to collect and "collect" light in order to focus it and direct it to where it is available. The problem with reflecting light sources is that most of the light produced becomes unusable, otherwise known as lumen loss. Any internal reflection of more than one reflection effectively loses one lumen of light.

Let's take a metal halide bulb as an example. Like LEDs, they are also popular in commercial and industrial applications. However, unlike LEDs, they are not directional. So consider the particles of light produced by metal halide bulbs. In fact, very few particles are reflected off at least one surface and do not reach the ground. So when a light particle is produced, it is likely to hit the reflector of the light fixture, which then tries to direct it to the floor.

Agar bu muvaffaqiyatli bo'lmasa, jarayonni takrorlash uchun yoritgich reflektorining boshqa qismiga yuboriladi. Bu vaqtda yorug'lik zarrasining qiymati yo'qoladi. Bu jarayonda samarali lümenlaringizning 30 foizini yo'qotishingiz mumkinligi ko'rsatilgan. Biroq, siz LED yoritgichidan foydalanganda, siz uning yorug'lik zarralarining hammasi bo'lmasa ham, ko'pini olasiz.

Yaxshiroq lümeningiz bo'lsa, sizga kamroq lümen kerak bo'ladi. Har qanday manbadan (hatto quyoshdan ham) yorug'lik sifati rang berish indeksi (CRI) bilan o'lchanadi. CRI - bu ma'lum bir yorug'lik manbai ostida ishlab chiqarilgan rangning aniqligini o'lchash uchun ishlatiladigan shkala. Albatta, oltin standart 100 ballga ega bo'lgan Quyoshdir. Boshqa barcha ballar 1 dan 100 gacha bo'lgan shkalada edi.

The best explanation for light quality is to perform a simple test. Let's compare LEDs with high pressure sodium (HPS) lamps. In our experience, people often tell you that a 20,000 lumen LED is much brighter than a 60,000 lumen HPS. This is because LEDs have a CRI of 70 plus and an HPS of 22.
