Comparative advantages of 2835, 3014 and 3528 lamp bead applications

1. Since the 3528 lamp bead is conducted to the negative electrode through the wire, the heat dissipation mode of the 3528 lamp bead can also be called “negative heat dissipation”;

2. 2835,3014 lamp beads and is passed over by the punch holder and the lamp loaded beads thermally conductive sheet, the heat conduction directly to the aluminum substrate, for

Different from the 3528 heat dissipation method, its heat dissipation method is also called “thermoelectric separation”, which means that heat and current do not pass through the same wire.

To conduct.
The picture below shows the physical picture of 3014 lamp beads, 2835 lamp beads and 3528 lamp beads:

2. The main reasons for 2835 and 3014 to replace 3528 in the market:

1. Because of their different package structure, they have better heat dissipation performance and can work normally at 30mA (normal understanding).

2. Deep-seated reasons, 2835, 3014 cost is more free to control, too much cat, unclear? Look down!

Three: 3528 light source benefits:

1. LED lamp bead 3528 can now achieve 7-8lm, single lamp bead power is 0.0625w, the market price does not include tax between 0.10~0.13 yuan (the size and grade of the LED chip used are different, which determines the price is different. If the chip uses A product, special product, B product, etc., it is also the brightness of 7-8LM, the quality can be very different, the price is of course different); therefore, now the quality of the light source is not the same as before, just look The brightness of the LED depends on the grade of the LED chip used. A product, special product or B product. The quality of the light source is flawed. It can be revealed at once. The manufacturer dares to use it. It is easy to understand that it is not easy to distinguish the quality. It takes time. To prove;

2. Lamp 3528 has a long use time, the production process and quality are relatively stable, and the brightness is also 7-8LM, mainly because the cost is relatively high, because the W number is only 0.0625W single, and the number is used to supplement the W number.

Four: 2835 and 3014 LED light source benefits:

1. The difference between the price of the medium power chip and the small power chip has gradually narrowed, and the price difference is not too big.

2. 2835 and 3014 brightness are: 10~12lm Single lamp bead 0.1w, 30mA drive, the current market price does not include tax: 0.10-0.17 yuan, see this, you may have a big question, 2835 Why is the same brightness as 3014? 10-12LM, different factory production, the price will be so different, sell 100 yuan / K? Also, sell 170 yuan / K? The difference of 70 yuan difference. We have done 9 years of LED light source packaging, the reason is actually very simple, nothing more than the cost of the chip is not the same, the price is naturally different. Nowadays, many factories are viciously competing in the market, fighting price wars, and blindly “saving” costs. It is indeed less conscience to behave and do things. Let me explain where the difference in cost is:

Why can I make 10-12LM brightness with different chips 2835 or 3014?

1. 0.1W medium power chip, driven by 30mA, the normal brightness is about 11-12LM (9*26mil, 12*28mil 12*24mil and other 0.1W chips), in line with the chip usage requirements, the quality is guaranteed.

2. 0.0625W low power chip, driven by 30mA, the brightness can also reach 9-12LM (using chip: 10*16, 10*18, 9*21mil, 10*23mil), but the brightness is current To push up is not the normal working brightness of the chip. These chips, strictly speaking, can only be driven by up to 20mA, but now some poor manufacturers use 30mA to drive, which is a very irresponsible practice. 2835, 3014 bracket heat dissipation is better, not afraid! LED light decay? That is after a year and a half, when will my factory survive? I don't know, I want to die, but others die first! The cost can be saved a lot, this is the main reason!

3528 lamp application on the LED tube cost comparison, such as T8 1.2 m 18w LED tube:

Use 3528:

18W ÷ 0.0625W / piece = 288, calculated according to the brightness of the light source: 288 * 7LM = 2016LM

Light source cost: 288 * 0.12 yuan / piece = 38 yuan

Use 2835, 3014:

18W ÷ 0.1W / piece = 180 pieces (but now on the market, the same 18W LED tube, the number of 3528, 3014 used beads vary greatly, useful 120, 144, 168, 172 The same, 180 and so on... The same point LED tube power is 18W, the difference is

The number of lamps in 2835 or 3014 (120-180) varies greatly from factory to factory, and the amount of material cuts is reduced.)

The plan compares the cost performance advantages of 2835, 3014 and 3528 lamp beads on the LED tube. I wrote it here and found that it can't be compared. There is no way to compare it, because the quality of the chip materials and the materials of the lamp beads are used in each factory. The quantity is uneven, there is no comparability at all, just as we are now

LED tube market, chaos! From the price analysis, the so-called experts, want to see clearly, it is not so easy, why a T8 1.2 m 18W LED tube, the market has 45 yuan / support, there are 70 yuan / support, 100 yuan / support, 130 yuan / support,

2835:18W÷0.1=180, our 2835 number is 168Pcs, the LED tube is less than 18W, there is also the suspect of stealing the material, but the high current drive 2835 is not used to push the foot 18W, the light source brightness calculation: 168 *11LM=1848LM Compared with the 3528 lamp bead 2016LM, the brightness is less. Light source cost: 168 * 0.16 yuan / piece = 27 yuan, a single T8 1.2 m 18W lamp source cost less than 11 yuan.

In summary, a penny, a point of goods, expensive and expensive, flat and flat reasons, 2835 or 3014 can not replace 3528, 3528 can not beat, the same 3528 chip is too different, not to mention there are 2835 and 3015, is a word "chaos", anyway, at a reasonable cost is that, of course, the market will make the final decision, 2835 or 3014, let the market decide! Let the guests decide! Time will be the best proof!
