Yuannengji There are many models and specifications of LED chips:
LED çiplərinin çoxlu modeli var, o cümlədən birbaşa daxiletmə növü, SMD növü, and high-power lamp bead type. The lamp bead current ranges from tens of milliamperes to several amperes, və gərginlik nisbətən sabitdir, mostly above three volts, so there is no way to generalize.
Roughly speaking, they are divided into direct-insert type, SMD növü, and piranha type according to the package, and divided into high, medium, and low power according to the power.
High-power white LED (CREE XML-T6 kimi) 10 Vt tək gücə malikdir, gərginlik 3.3V, və cərəyan 3A. Low-power red LED (məsələn, ümumi 5MM birbaşa daxiletmə növü) 2v gərginliyə və 15mA cərəyana malikdir. 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, amma istisnalar var;
SMD package is 3014, 3528, 3535 and other low-power tubes, the working current is 20~50mA, amma istisnalar var;
SMD package is 5050, 5060, 5630 and other medium-power tubes, the working current is 50~150mA, amma istisnalar var;
Yüksək güclü LED-lərin hamısı SMD paketləridir, 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, gərginlik 2.5-3.5V, cərəyan 20mA.
2. 0.5W, gərginlik 2.5-3.77V, cərəyan 150mA.
3, 1W, gərginlik 2.79-3.99V, cərəyan 350mA.
4, 3W, gərginlik 3.05-4.47V, cərəyan 700mA.
5, 5W, gərginlik 3.16-4.88V, cərəyan 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. Məsələn, cree mce, cree t6.
Gərginlik: 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. Parlaqlığa baxın, yəni, sürücülük cərəyanı 350mA və gərginlik 3.0-3.6V arasında olduqda parlaqlıq. Nə qədər yüksəksə, bir o qədər yaxşıdır.
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, yəni, color temperature partition and voltage BIN, the finer the better.
4. Look at attenuation. Yaşlanma testi tələb olunur. İşığın zəifləməsi nə qədər kiçik olar, daha yaxşı.
5. Həqiqi tətbiqə baxın, kimi: bazarda uyğun və ucuz linzaların və alüminium substratların olması yaxşıdır. If the lens and aluminum substrate need to be molded, the investment will be large. 1W yüksək güc, cari: 350ma, gərginlik: 2.8-4.0V parlaqlıq: 80-130LM rəng temperaturu: 3000-12000Kaş.
