YUANNENGJI LED chip models and specifications. As someone in the LED chip industry, even if you are not familiar with it, you must have a certain understanding of LED chips. Let me introduce it to you.
LED chip models
Terlalu banyak model chip LED, termasuk tipe penyisipan langsung, Tipe SMD, and high-power LED chips. The current of LED chips ranges from tens of milliamperes to several amperes, dan tegangan relatif konsisten, mostly around three or four volts. According to the LED package, it is divided into direct-insert type LED and SMD type LED; according to the power, it is divided into high, medium and low power.
High-power white light LED (seperti CREE XML-T6) memiliki daya tunggal 10W, tegangan 3.3V, dan arus 3A. Low-power red light LED (seperti tipe sisipan langsung 5MM yang umum) memiliki tegangan 2v dan arus 15mA.
The SMD package is a low-power light-emitting diode such as 0805, 1206, and the working current is generally 10mA, tetapi ada pengecualian. The SMD package is for low-power LED tubes such as 3014, 3528, 3535, and the operating current is generally 20~50mA, tetapi ada pengecualian; the SMD package is for high-power LED tubes such as 2835, 5050, 5060, 5630, and the operating current is generally 50~150mA, tetapi ada pengecualian;
LED daya tinggi adalah semua paket SMD, and the parameters of different brands and series of different companies vary greatly; but the general operating current of the nominal 1W is 350mA.
Low-power direct-insert LED chips are generally divided into models according to diameter, 3mm 4mm 5mm 8mm 10mm 12mm. Regardless of the diameter, the operating voltage and operating current are the same.
LED chip specifications:
(1) 0.06W, tegangan 2,5-3,5V, arus 20mA.
(2) 0.5W, tegangan 2,5-3,77V, arus 150mA.
(3) 1W, tegangan 2,79-3,99V, arus 350mA.
(4) 3W, tegangan 3,05-4,47V, arus 700mA.
(5) 5W, tegangan 3,16-4,88V, arus 1000mA.
1W LED chip current 320-350mA. The driver is usually 300mA. The LED chip size is 30mil, 35mil, 40mil, 45mil. The 3W LED chip current is 700mA, the driver is generally 600mA, and the LED chip size is 45mil.
The voltage of 1W and 3W is between 3.0-3.6V, and the better ones are 3.2-3.4V. As for the 5W single LED chip, it is generally above 50mil. Other parameters are unclear. The LED chip used for general lighting is between 0.5w-5w, and the working voltage is about 3-3.2V.
There are several ways to identify LED chips:
1. Perhatikan kecerahan, yaitu, kecerahan saat arus penggerak 350mA dan tegangan antara 3,0-3,6V. Semakin tinggi semakin baik.
2. Look at the BIN, yaitu, the color temperature partition and voltage BIN. The finer the better.
3. Look at the attenuation. Diperlukan uji penuaan. Semakin kecil reduksi cahaya, semakin baik.
4. Perhatikan aplikasi sebenarnya. Misalnya, baik jika ada lensa dan substrat aluminium yang cocok dan murah di pasaran. Lenses and aluminum substrates need to be molded, and the cost will be higher. 1Daya tinggi W, arus: 350mA, tegangan: 2.8-4.0Kecerahan V: 80-130Suhu warna LM: 3000-12000K.
