YUANNENGJI Kaping pisanan, LED chips have BIN and gear differences. Different BIN and gear need to be mixed according to regulations, otherwise there will be color difference and other undesirable conditions. The BIN and BIN color mixing schemes of particles produced by different companies are also different. It depends on the BIN color mixing scheme provided by the light source supplier. When you can’t mix BIN, it is recommended to use a single BIN.
Let’s talk about BIN first. BIN is actually a relatively abstract concept. Ing urip, humans evaluate color consistency. White has beige, putih resik, and milky white, and green has dark green and light green. Kanggo chip LED, the same 3,000K color temperature will have different colors from different light sources.
In the process of light source selection, warna cahya lan tes listrik bakal ditindakake kanggo entuk koordinat warna. Koordinat warna tiba ing macem-macem posisi ing elips MacAdam, lan werna bakal beda. For example, sanajan titik abang ing macem-macem wilayah elips MacAdam 3000K kalebu ing kisaran 3000K, mripat manungsa isih bisa nemokake prabédan ing werna. Mulane, supplier sumber cahya bakal dibagi kabeh 3000K sawetara menyang sawetara wilayah, kayata papat wilayah ABCD ing gambar ndhuwur, kang dadi papat BIN beda. For example, limang titik abang (koordinat werna) ing tokoh ndhuwur tiba menyang sekat beda.
Next, ayo ngomong babagan gear. Generally, pindah ditemtokake miturut prabédan chip saka sumber cahya dhewe. Klasifikasi sing luwih umum yaiku voltase / gear saiki lan gear lumen (gear fluks cahya). Ing proses produksi kemasan sumber cahya, pabrik gedhe duwe output ageng lan ora bisa njamin yen produk padha diprodhuksi ing wektu sing padha duwe voltase padha, saiki, lan output fluks cahya. Mulane, sawise produk rangkep diprodhuksi, dheweke bakal ngliwati proses sing diarani “pilihan optik”, yaiku, sumber cahya diklasifikasikaké nggunakake sorter optik. Sumber cahya sing diklasifikasikake bakal dipérang dadi pirang-pirang kategori, yaiku “gir”, miturut voltase beda, arus, lan output fluks padhang.
For example, subdivisi gear sumber cahya umum (ora pinunjul praktis, mung kanggo referensi):
Gear A: voltase 2.9-3.0V, fluks cahya 21-23lm
Gear B: voltase 3.0-3.1V, fluks cahya 23-25lm
Gear C: voltase 3.1-3.2V, fluks cahya 25-27lm
Ing istilah prasaja, yaiku kanggo mbagi partisi suhu warna supaya warna sumber cahya ing partisi suhu warna sing padha tetep konsisten..
