Yunanengji There are many models and specifications of LED chips:
LED chiplarining juda ko'p modellari mavjud, To'g'ridan-to'g'ri kiritish turi, Smd turi, and high-power lamp bead type. The lamp bead current ranges from tens of milliamperes to several amperes, va kuchlanish nisbatan izchil, mostly above three volts, so there is no way to generalize.
Roughly speaking, they are divided into direct-insert type, Smd turi, and piranha type according to the package, and divided into high, medium, and low power according to the power.
High-power white LED (masalan, Cree XML-T6) bir nechta kuchga ega, 3,3V kuchlanishi, va 3a oqimi. Low-power red LED (masalan, 5mm to'g'ridan-to'g'ri kiritish turi) 2V kuchlanishiga va 15MA oqimi mavjud. 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, Ammo istisnolar mavjud;
SMD package is 3014, 3528, 3535 and other low-power tubes, the working current is 20~50mA, Ammo istisnolar mavjud;
SMD package is 5050, 5060, 5630 and other medium-power tubes, the working current is 50~150mA, Ammo istisnolar mavjud;
Yuqori quvvatli LEDlar SMD paketlari, 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 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. 0.06Shilmoq, 2,5-3.5V kuchlanish, Joriy 20MA.
2. 0.5Shilmoq, 25-3.77V kuchlanish, Joriy 150MA.
3, 1Shilmoq, 2.79-3.99V kuchlanish, Joriy 350MA.
4, 3Shilmoq, Voltage 3.05-4.47V, Joriy 700MA.
5, 5Shilmoq, Voltage 3.16-4.88V, Hozirgi 1000MA.
1W lamp bead current: 320-350mA, the driver generally chooses 300mA current, and the chip size is 30mil, 35mil, 40mil, 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 lamp beads? 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. Masalan, cree mce, cree t6.
Voltage: 3.2-3.6v, current 300-350ma, luminous flux: 100-120 lumens, color temperature: white light 6000-7000K.
Methods to identify LED chips are:
1. Yorqinlikka qarang, bu, Haydohlik oqimi 350m, va kuchlanish 3,0-3,6V gacha bo'lganida yorqinlik. Qanchalik yaxshi bo'lsa.
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, bu, color temperature partition and voltage BIN, the finer the better.
4. Look at attenuation. Qarish testi talab qilinadi. Kichikroq yorug'lik kuchayishi, Yaxshisi.
5. Haqiqiy buyurtmani ko'rib chiqing, such as: Bozordagi mos va arzon ob'ektivlar va alyuminiy substratlarga ega bo'lish yaxshi. If the lens and aluminum substrate need to be molded, the investment will be large. 1W yuqori quvvat, hozirgi: 350mayin, Kuchlanishi: 2.8-4.0V yorqinlik: 80-130Lm rang harorati: 3000-12000K.
