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
Modelov LED čipov je preveč, vključno z neposrednim vstavljanjem, Tip SMD, and high-power LED chips. The current of LED chips ranges from tens of milliamperes to several amperes, in napetost je relativno dosledna, 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 (kot je XML-T6 podjetja CREE) ima enkratno moč 10W, napetost 3,3 V, in tok 3A. Low-power red light LED (kot je običajni tip 5MM z neposrednim vstavljanjem) ima napetost 2V in tok 15mA.
The SMD package is a low-power light-emitting diode such as 0805, 1206, and the working current is generally 10mA, vendar obstajajo izjeme. The SMD package is for low-power LED tubes such as 3014, 3528, 3535, and the operating current is generally 20~50mA, vendar obstajajo izjeme; the SMD package is for high-power LED tubes such as 2835, 5050, 5060, 5630, and the operating current is generally 50~150mA, vendar obstajajo izjeme;
Svetleče diode visoke moči so vse pakete 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, napetost 2,5-3,5V, tok 20mA.
(2) 0.5W, napetost 2,5-3,77V, tok 150mA.
(3) 1W, napetost 2,79-3,99V, tok 350mA.
(4) 3W, napetost 3,05-4,47V, tok 700mA.
(5) 5W, napetost 3,16-4,88V, tok 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. Poglejte svetlost, to je, svetlost, ko je pogonski tok 350 mA in napetost med 3,0-3,6 V. Višje, bolje je.
2. Look at the BIN, to je, the color temperature partition and voltage BIN. The finer the better.
3. Look at the attenuation. Potreben je test staranja. Čim manjša je slabitev svetlobe, tem bolje.
4. Poglejte dejansko aplikacijo. Na primer, dobro je imeti na trgu ustrezne in poceni leče in aluminijaste podlage. Lenses and aluminum substrates need to be molded, and the cost will be higher. 1W velika moč, trenutno: 350ma, napetost: 2.8-4.0V svetlost: 80-130Barvna temperatura LM: 3000-12000K.
