YUANNENGJI Modelos e especificações de chips LED. 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
Existem muitos modelos de chips LED, incluindo tipo de inserção direta, Tipo SMD, and high-power LED chips. The current of LED chips ranges from tens of milliamperes to several amperes, e a tensão é relativamente consistente, 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 (como XML-T6 do CREE) tem uma única potência de 10W, uma tensão de 3,3v, e uma corrente de 3A. Low-power red light LED (como o tipo comum de inserção direta de 5MM) tem uma tensão de 2v e uma corrente de 15mA.
The SMD package is a low-power light-emitting diode such as 0805, 1206, and the working current is generally 10mA, mas há exceções. The SMD package is for low-power LED tubes such as 3014, 3528, 3535, and the operating current is generally 20~50mA, mas há exceções; o Pacote SMD is for high-power LED tubes such as 2835, 5050, 5060, 5630, and the operating current is generally 50~150mA, mas há exceções;
LEDs de alta potência são todos pacotes 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) 0.06C, tensão 2,5-3,5V, corrente 20mA.
(2) 0.5C, tensão 2,5-3,77V, corrente 150mA.
(3) 1C, tensão 2,79-3,99V, corrente 350mA.
(4) 3C, tensão 3,05-4,47V, corrente 700mA.
(5) 5C, tensão 3,16-4,88V, corrente 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. Olhe o brilho, ou seja,, o brilho quando a corrente de acionamento é 350mA e a tensão está entre 3,0-3,6V. Quanto mais alto melhor.
2. Look at the BIN, ou seja,, the color temperature partition and voltage BIN. The finer the better.
3. Look at the attenuation. O teste de envelhecimento é obrigatório. Quanto menor a atenuação da luz, melhor.
4. Veja a aplicação real. Por exemplo, é bom ter lentes e substratos de alumínio adequados e baratos no mercado. Lenses and aluminum substrates need to be molded, and the cost will be higher. 1W alta potência, atual: 350mãe, tensão: 2.8-4.0V brilho: 80-130Temperatura de cor LM: 3000-12000K.
