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
Adunay daghan kaayo nga mga modelo sa LED chips, lakip ang direktang-insert type, SMD nga tipo, and high-power LED chips. The current of LED chips ranges from tens of milliamperes to several amperes, ug ang boltahe medyo makanunayon, 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 (sama sa XML-T6 sa CREE) adunay usa ka gahum sa 10W, usa ka boltahe sa 3.3v, ug usa ka kasamtangan nga 3A. Low-power red light LED (sama sa kasagaran nga 5MM nga direktang pagsulud nga tipo) adunay boltahe nga 2v ug usa ka kasamtangan nga 15mA.
The SMD package is a low-power light-emitting diode such as 0805, 1206, and the working current is generally 10mA, apan adunay mga eksepsiyon. The SMD package is for low-power LED tubes such as 3014, 3528, 3535, and the operating current is generally 20~50mA, apan adunay mga eksepsiyon; the SMD package is for high-power LED tubes such as 2835, 5050, 5060, 5630, and the operating current is generally 50~150mA, apan adunay mga eksepsiyon;
Ang mga high-power LEDs tanan nga mga pakete sa 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, boltahe 2.5-3.5V, kasamtangan nga 20mA.
(2) 0.5W, boltahe 2.5-3.77V, kasamtangan nga 150mA.
(3) 1W, boltahe 2.79-3.99V, kasamtangan nga 350mA.
(4) 3W, boltahe 3.05-4.47V, kasamtangan nga 700mA.
(5) 5W, boltahe 3.16-4.88V, kasamtangan nga 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. Tan-awa ang kahayag, mao, ang kahayag sa diha nga ang nagmaneho kasamtangan mao ang 350mA ug ang boltahe sa taliwala sa 3.0-3.6V. Ang mas taas mas maayo.
2. Look at the BIN, mao, the color temperature partition and voltage BIN. The finer the better.
3. Look at the attenuation. Gikinahanglan ang pagsulay sa pagkatigulang. Ang mas gamay sa kahayag attenuation, mas maayo.
4. Tan-awa ang aktuwal nga aplikasyon. For example, maayo nga adunay angay ug barato nga mga lente ug mga substrate sa aluminyo sa merkado. Lenses and aluminum substrates need to be molded, and the cost will be higher. 1W taas nga gahum, kasamtangan: 350ma, boltahe: 2.8-4.0V kahayag: 80-130LM kolor temperatura: 3000-12000K.
