YUANNENGJI There are many models and specifications of LED chips:
There are too many models of LED chips, including direct-insert type, SMD type, and high-power lamp bead type. The lamp bead current ranges from tens of milliamperes to several amperes, and the voltage is relatively consistent, mostly above three volts, so there is no way to generalize.
Roughly speaking, they are divided into direct-insert type, SMD type, and piranha type according to the package, and divided into high, medium, and low power according to the power.
High-power white LED (such as CREE’s XML-T6) мае адзінкавую магутнасць 10 Вт, напружанне 3,3 В, and a current of 3A. Low-power red LED (напрыклад, звычайны тып 5 мм з прамой устаўкай) мае напружанне 2 В і сілу току 15 мА. 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, але бываюць выключэнні;
SMD package is 3014, 3528, 3535 and other low-power tubes, the working current is 20~50mA, але бываюць выключэнні;
SMD package is 5050, 5060, 5630 and other medium-power tubes, the working current is 50~150mA, але бываюць выключэнні;
Святлодыёды высокай магутнасці - гэта пакеты SMD, 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 4 мм 5 мм 8 мм 10 мм 12 мм, 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. 0.06В, напряжэнне 2.5-3.5В, ток 20мА.
2. 0.5В, напряжэнне 2.5-3.77В, ток 150мА.
3, 1В, напряжэнне 2.79-3.99В, ток 350мА.
4, 3В, напряжэнне 3.05-4.47В, ток 700мА.
5, 5В, напряжэнне 3.16-4.88В, ток 1000мА.
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 Святлодыёдныя лямпы пацеркі? We generally design them to be 3.6—4.2V, 0.2—0.3А. There are many 15W lamp beads now, you can refer to them. Напрыклад, 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. Паглядзіце на яркасць, гэта значыць, яркасць, калі ток кіравання 350мА і напружанне паміж 3.0-3.6В. Чым вышэй, тым лепш.
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, гэта значыць, color temperature partition and voltage BIN, the finer the better.
4. Look at attenuation. Неабходны тэст на старэнне. Чым меншае згасанне святла, тым лепш.
5. Паглядзіце на сапраўднае прыкладанне, such as: добра мець на рынку прыдатныя і танныя лінзы і алюмініевыя падкладкі. If the lens and aluminum substrate need to be molded, the investment will be large. 1W высокая магутнасць, ток: 350ма, напруга: 2.8-4.0V яркасць: 80-130Каляровая тэмпература LM: 3000-12000K.
