YUANNENGJI There are many models and specifications of LED chips:
Постоји превише модела ЛЕД чипова, укључујући тип директног уметања, СМД тип, and high-power lamp bead type. The lamp bead current ranges from tens of milliamperes to several amperes, а напон је релативно конзистентан, mostly above three volts, so there is no way to generalize.
Roughly speaking, they are divided into direct-insert type, СМД тип, and piranha type according to the package, and divided into high, medium, and low power according to the power.
High-power white LED (као што је ЦРЕЕ КСМЛ-Т6) има појединачну снагу од 10В, напон од 3,3в, и струја од 3А. Low-power red LED (као што је уобичајени тип директног уметања од 5 мм) има напон од 2в и струју од 15мА. 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, али има изузетака;
SMD package is 3014, 3528, 3535 and other low-power tubes, the working current is 20~50mA, али има изузетака;
SMD package is 5050, 5060, 5630 and other medium-power tubes, the working current is 50~150mA, али има изузетака;
ЛЕД диоде велике снаге су сви СМД пакети, 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, 3мм 4мм 5мм 8мм 10мм 12мм, regardless of the diameter, the working voltage and working current are the same, color classification: red light
yellow light 1.7–2.1В
white light blue light warm white light pink light purple light 2.8–3.6В
green light 2.6–3.4В
LED chips have a variety of specifications
1. 0.06В, напон 2,5-3,5В, струја 20мА.
2. 0.5В, напон 2,5-3,77В, струја 150мА.
3, 1В, напон 2,79-3,99В, струја 350мА.
4, 3В, напон 3,05-4,47В, струја 700мА.
5, 5В, напон 3,16-4,88В, струја 1000мА.
1W lamp bead current: 320-350мА, the driver generally chooses 300mA current, and the chip size is 30mil, 35мил, 40мил, and 45mil.
3W lamp bead current: 700мА, 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 Перле ЛЕД лампе? We generally design them to be 3.6—4.2В, 0.2—0.3А. There are many 15W lamp beads now, you can refer to them. Na primer, 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. Погледајте осветљеност, односно, осветљеност када је струја покретања 350мА и напон између 3,0-3,6В. Што више, то боље.
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, односно, color temperature partition and voltage BIN, the finer the better.
4. Look at attenuation. Потребан је тест старења. Што је слабљење светлости мање, то боље.
5. Погледајте стварну апликацију, such as: добро је на тржишту имати одговарајућа и јефтина сочива и алуминијумске подлоге. If the lens and aluminum substrate need to be molded, the investment will be large. 1В велике снаге, струја: 350ма, напон: 2.8-4.0В осветљеност: 80-130ЛМ температура боје: 3000-12000К.
