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
Existuje príliš veľa modelov LED čipov, vrátane typu s priamou vložkou, Typ SMD, and high-power LED chips. The current of LED chips ranges from tens of milliamperes to several amperes, a napätie je relatívne konzistentné, 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 (ako je XML-T6 spoločnosti CREE) má jeden výkon 10W, napätie 3,3V, a prúd 3A. Low-power red light LED (ako je bežný 5MM typ s priamou vložkou) má napätie 2V a prúd 15mA.
The SMD package is a low-power light-emitting diode such as 0805, 1206, and the working current is generally 10mA, ale su vynimky. The SMD package is for low-power LED tubes such as 3014, 3528, 3535, and the operating current is generally 20~50mA, ale su vynimky; the SMD package is for high-power LED tubes such as 2835, 5050, 5060, 5630, and the operating current is generally 50~150mA, ale su vynimky;
Vysokovýkonné LED diódy sú všetky balíčky 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 4 mm 5 mm 8 mm 10 mm 12 mm. Regardless of the diameter, the operating voltage and operating current are the same.
LED chip specifications:
(1) 0.06W, napätie 2,5-3,5V, prúd 20mA.
(2) 0.5W, napätie 2,5-3,77V, prúd 150mA.
(3) 1W, napätie 2,79-3,99V, prúd 350mA.
(4) 3W, napätie 3,05-4,47V, prúd 700mA.
(5) 5W, napätie 3,16-4,88V, prúd 1000 mA.
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. Pozrite sa na jas, to jest, jas pri budiacom prúde 350mA a napätí medzi 3,0-3,6V. Čím vyššie, tým lepšie.
2. Look at the BIN, to jest, the color temperature partition and voltage BIN. The finer the better.
3. Look at the attenuation. Vyžaduje sa test starnutia. Čím menší je útlm svetla, tým lepšie.
4. Pozrite sa na skutočnú aplikáciu. Napríklad, je dobré mať na trhu vhodné a lacné šošovky a hliníkové substráty. Lenses and aluminum substrates need to be molded, and the cost will be higher. 1W vysoký výkon, prúd: 350ma, napätie: 2.8-4.0V jas: 80-130Teplota farby LM: 3000-12000K.
