YUANNENGJI There are many models and specifications of LED chips:
Existuje příliš mnoho modelů LED čipů, včetně typu s přímým vložením, Typ SMD, and high-power lamp bead type. The lamp bead current ranges from tens of milliamperes to several amperes, a napětí je relativně konzistentní, mostly above three volts, so there is no way to generalize.
Roughly speaking, they are divided into direct-insert type, Typ SMD, and piranha type according to the package, and divided into high, medium, and low power according to the power.
High-power white LED (jako je XML-T6 společnosti CREE) má jeden výkon 10W, napětí 3,3V, a proud 3A. Low-power red LED (jako je běžný 5MM typ s přímou vložkou) má napětí 2V a proud 15mA. 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, ale jsou výjimky;
SMD package is 3014, 3528, 3535 and other low-power tubes, the working current is 20~50mA, ale jsou výjimky;
SMD package is 5050, 5060, 5630 and other medium-power tubes, the working current is 50~150mA, ale jsou výjimky;
Vysoce výkonné LED jsou všechny SMD pouzdra, 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 4 mm 5 mm 8 mm 10 mm 12 mm, regardless of the diameter, the working voltage and working current are the same, color classification: red light
yellow light 1.7–2.1PROTI
white light blue light warm white light pink light purple light 2.8–3.6PROTI
green light 2.6–3.4PROTI
LED chips have a variety of specifications
1. 0.06W, napětí 2,5-3,5V, proud 20mA.
2. 0.5W, napětí 2,5-3,77V, proud 150mA.
3, 1W, napětí 2,79-3,99V, proud 350mA.
4, 3W, napětí 3,05-4,47V, proud 700 mA.
5, 5W, napětí 3,16-4,88 V, proud 1000 mA.
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 Korálky LED lampy? We generally design them to be 3.6—4.2PROTI, 0.2—0.3A. There are many 15W lamp beads now, you can refer to them. Například, cree mce, cree t6.
Napětí: 3.2-3.6v, current 300-350ma, luminous flux: 100-120 lumens, barevná teplota: white light 6000-7000K.
Methods to identify LED chips are:
1. Podívejte se na jas, to je, jas při budícím proudu 350mA a napětí mezi 3,0-3,6V. Čím vyšší, tím lepší.
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, to je, color temperature partition and voltage BIN, the finer the better.
4. Look at attenuation. Je vyžadován test stárnutí. Čím menší je útlum světla, tím lépe.
5. Podívejte se na skutečnou aplikaci, jako: je dobré mít na trhu vhodné a levné čočky a hliníkové substráty. If the lens and aluminum substrate need to be molded, the investment will be large. 1W vysoký výkon, proud: 350ma, napětí: 2.8-4.0V jas: 80-130LM barevná teplota: 3000-12000K.
