LED Chip Models and LED Chip specifications

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

Có quá nhiều mẫu chip LED, bao gồm loại cắm trực tiếp, loại SMD, and high-power LED chips. The current of LED chips ranges from tens of milliamperes to several amperes, và điện áp tương đối ổn định, 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 (như CREE XML-T6) có công suất đơn 10W, điện áp 3,3v, và dòng điện 3A. Low-power red light LED (chẳng hạn như loại chèn trực tiếp 5MM phổ biến) có điện áp 2v và dòng điện 15mA.

The SMD package is a low-power light-emitting diode such as 0805, 1206, and the working current is generally 10mA, nhưng có những trường hợp ngoại lệ. The SMD package is for low-power LED tubes such as 3014, 3528, 3535, and the operating current is generally 20~50mA, nhưng có những trường hợp ngoại lệ; the SMD package is for high-power LED tubes such as 2835, 5050, 5060, 5630, and the operating current is generally 50~150mA, nhưng có những trường hợp ngoại lệ;

Đèn LED công suất cao là tất cả các gói 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, điện áp 2,5-3,5V, dòng điện 20mA.

(2) 0.5W, điện áp 2,5-3,77V, dòng điện 150mA.

(3) 1W, điện áp 2,79-3,99V, dòng điện 350mA.

(4) 3W, điện áp 3,05-4,47V, dòng điện 700mA.

(5) 5W, điện áp 3,16-4,88V, dòng điện 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. Look at the brightness, tức là, the brightness when the driving current is 350mA and the voltage is between 3.0-3.6V. The higher the better.

2. Look at the BIN, tức là, the color temperature partition and voltage BIN. The finer the better.

3. Look at the attenuation. Aging test is required. The smaller the light attenuation, the better.

4. Look at the actual application. Chẳng hạn, it is good to have suitable and cheap lenses and aluminum substrates on the market. Lenses and aluminum substrates need to be molded, and the cost will be higher. 1W high power, dòng điện: 350ma, voltage: 2.8-4.0V brightness: 80-130Nhiệt độ màu LM: 3000-12000K.
