YUANNENGJI There are many models and specifications of LED chips:
Ir pārāk daudz LED mikroshēmu modeļu, ieskaitot tiešās ievietošanas veidu, SMD tips, and high-power lamp bead type. The lamp bead current ranges from tens of milliamperes to several amperes, un spriegums ir samērā nemainīgs, mostly above three volts, so there is no way to generalize.
Roughly speaking, they are divided into direct-insert type, SMD tips, and piranha type according to the package, and divided into high, medium, and low power according to the power.
High-power white LED (piemēram, CREE XML-T6) ir viena jauda 10W, spriegums 3,3 V, un strāva 3A. Low-power red LED (piemēram, parastais 5MM tiešās ievietošanas veids) ir spriegums 2v un strāva 15mA. If you really can’t find the component model, you can infer the working voltage based on the light color:
Red light 1.8~2.2v
Yellow light 2.0~2.4v
Green light 2.2~2.8v
Blue and white light 2.8~3.5v
SMD package is 0805, 1206 and other low-power tubes, the working voltage is 10mA, bet ir izņēmumi;
SMD package is 3014, 3528, 3535 and other low-power tubes, the working current is 20~50mA, bet ir izņēmumi;
SMD package is 5050, 5060, 5630 and other medium-power tubes, the working current is 50~150mA, bet ir izņēmumi;
Lieljaudas gaismas diodes ir visas SMD paketes, and the parameters of different brands and company series vary greatly; but the general working current of the nominal 1W is 350mA
Low-power direct-plug LED chip are generally divided into models according to diameter, 3mm 4mm 5mm 8mm 10mm 12mm, regardless of the diameter, the working voltage and working current are the same, color classification: red light
yellow light 1.7–2.1V
white light blue light warm white light pink light purple light 2.8–3.6V
green light 2.6–3.4V
LED chips have a variety of specifications
1. 0.06W, spriegums 2,5-3,5V, strāva 20mA.
2. 0.5W, spriegums 2,5-3,77V, strāva 150mA.
3, 1W, spriegums 2,79-3,99V, strāva 350mA.
4, 3W, spriegums 3,05-4,47V, strāva 700mA.
5, 5W, spriegums 3,16-4,88V, strāva 1000mA.
1W lamp bead current: 320-350mA, the driver generally chooses 300mA current, and the chip size is 30mil, 35milj, 40milj, and 45mil.
3W lamp bead current: 700mA, the driver generally chooses 600mA, and the chip size is 45mil.
1W and 3W voltages are between 3.0-3.6V, and 3.2-3.4V is better.
As for a single 5W chip, the chip is generally more than 50mil.
LED chip for general lighting are 0.5w-5w, and the operating voltage is around 3-3.2V.
What are the parameters of 1-watt white light LED lampas krelles? We generally design them to be 3.6—4.2V, 0.2—0.3A. There are many 15W lamp beads now, you can refer to them. Piemēram, cree mce, cree t6.
Voltage: 3.2-3.6v, current 300-350ma, luminous flux: 100-120 lumens, krāsu temperatūra: white light 6000-7000K.
Methods to identify LED chips are:
1. Paskaties uz spilgtumu, tas ir, spilgtums, kad braukšanas strāva ir 350 mA un spriegums ir no 3,0 līdz 3,6 V. Jo augstāks, jo labāk.
2. Look at the chip brand. There are many LED chip brands on the market. It is very important to choose a reliable chip company
3. Look at BIN, tas ir, color temperature partition and voltage BIN, the finer the better.
4. Look at attenuation. Nepieciešams novecošanās tests. Jo mazāka ir gaismas vājināšanās, jo labāk.
5. Apskatiet faktisko pieteikumu, such as: ir labi, ja tirgū ir piemērotas un lētas lēcas un alumīnija substrāti. If the lens and aluminum substrate need to be molded, the investment will be large. 1W liela jauda, strāva: 350ma, spriegums: 2.8-4.0V spilgtums: 80-130LM krāsu temperatūra: 3000-12000K.
