YUANNENGJI There are many models and specifications of LED chips:
Yra per daug LED lustų modelių, įskaitant tiesioginio įterpimo tipą, SMD tipas, and high-power lamp bead type. The lamp bead current ranges from tens of milliamperes to several amperes, ir įtampa yra gana pastovi, mostly above three volts, so there is no way to generalize.
Roughly speaking, they are divided into direct-insert type, SMD tipas, and piranha type according to the package, and divided into high, medium, and low power according to the power.
High-power white LED (pvz., CREE XML-T6) turi vieną 10 W galią, 3,3 V įtampa, ir 3A srovė. Low-power red LED (pavyzdžiui, įprastas 5MM tiesioginio įterpimo tipas) turi 2v įtampą ir 15mA srovę. 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 yra išimčių;
SMD package is 3014, 3528, 3535 and other low-power tubes, the working current is 20~50mA, bet yra išimčių;
SMD package is 5050, 5060, 5630 and other medium-power tubes, the working current is 50~150mA, bet yra išimčių;
Didelės galios šviesos diodai yra visi SMD paketai, 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, įtampa 2,5-3,5V, srovė 20mA.
2. 0.5W, įtampa 2,5-3,77V, srovė 150mA.
3, 1W, įtampa 2,79-3,99V, srovė 350mA.
4, 3W, įtampa 3,05-4,47V, srovė 700mA.
5, 5W, įtampa 3,16-4,88V, srovė 1000mA.
1W lamp bead current: 320-350mA, the driver generally chooses 300mA current, and the chip size is 30mil, 35mln, 40mln, 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 lempos karoliukai? 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. Pavyzdžiui, cree mce, cree t6.
Voltage: 3.2-3.6v, current 300-350ma, luminous flux: 100-120 lumens, spalvos temperatūra: white light 6000-7000K.
Methods to identify LED chips are:
1. Pažiūrėkite į ryškumą, tai yra, ryškumas, kai varomoji srovė yra 350 mA, o įtampa yra nuo 3,0 iki 3,6 V. Kuo aukščiau, tuo geriau.
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, tai yra, color temperature partition and voltage BIN, the finer the better.
4. Look at attenuation. Būtinas senėjimo testas. Kuo mažesnis šviesos slopinimas, tuo geriau.
5. Pažiūrėkite į tikrąją programą, such as: gerai, kad rinkoje yra tinkami ir pigūs lęšiai ir aliuminio substratai. If the lens and aluminum substrate need to be molded, the investment will be large. 1W didelės galios, srovė: 350ma, įtampa: 2.8-4.0V ryškumas: 80-130LM spalvos temperatūra: 3000-12000K.
