Characteristics on SMD 2835 LED and main differences

Title: LEDs

Svrhyarki LEDs, which appeared relatively soon, veche began to know the sources of light. Those are included in lamps and tapes, they are sold separately and they are bundled into modules. Nai-popular smd 2835 diodes. With good features and relatively low price, they are widely used in lighting equipment for various purposes. In this article, we speak for the theses of semiconductors and devices, we will analyze how they are and how they differ from other types of LEDs.

Design and appearance

Externally, the LED is made of ceramic right-hand corner 2.8 mm x 3.5 mm (glare and digital marking). From one country to the right-hand side of the ima LED crystal, made with a protective connection, from another - contacts for surface mounting (smd outlet - surface-mounted device). These contacts serve for the protection of the crystal and in some time they play roles on the radiator, which is the separation of toplinate from the semiconductor.

Appear on smd 2835 LED

For yes, they will adjust the spectral characteristics and the change in color temperature is known, by combining this by adding special phosphorus. If you look carefully, you can see the crystal from the current and the conductors have a protective coating.

Specifications

Today's date smd 2835 LEDs are offered in three versions:

• 0.2W;
• 0.5W;
• 1 cotton

Vsichki those sa ednakvi on the external view and se distinguish themselves by the strength of the crystal, installed in the kutiyata. Osven tezi three types of LEDs, ima Chinese development with a power of 0.09 watts. The unit is usually fake with standard markings, but equipped with a crystal with a low power with a bright stream of 8 lumens.

So in the LED it’s evtin, but it’s very difficult to distinguish it from the normal patented LED navn - the crystal of innocence is clearly visible before the connection and it’s completely impossible to visually determine the size of the negativity. In the friendly documentation for the device, our Chinese friends can and will sip everything, they are looking for something. The only thing to start is not to fall on a counterfeit, and not to buy suspiciously the device.

Stop the characteristics on the LED, including the Chinese version, summarized in the table:

Application

Thanks to the kindness of light power, golemia on the spread, compactness and relatively low price, smd 2835 diodes are widely used in technology for clarification. Those are used for sglobyavane on LED lamps for general and local lighting, gradations in LED strips, which from their own country are used for both clarification and for decorative purposes.

You can mix smd 2835 in jobni fenerchet and tactical fenerchet. Lamp with low voltage, fold on the base, which is successfully used by motorists, who install it in the headlight and size instead of into the hulls from the pressed lamp.

These devices are very popular among engineers and designers for electronics, such as smd 2835 can be purchased separately or combined into modules with different shapes, sizes and capacities.

LED strip for LED 2835

LED lentite (SL) is widely used both for lightening and for decorative purposes.

SMD 2835 LED tape usually starts from 0.2 W smd LED, which is cooled by a device with a relatively conductive tape, which is a lot of problems. They break on the smd semiconductor at 1 m from SL, it can be different - 60 or 120. It saves the voltage of 12, 24 or 220 V between, and the value depends on the design and the presence of it on the block, and not on the light on the LED on the meter. For a product with a density of 60 LEDs / m, density per power and light power, parsing it, it will cost 2 five on the bottom.

SL 60 (clear) and 120 smd LEDs per meter

Important. LED strip on smd LEDs from Tosi type ima relatively high power and at the same time the trebva itself is attached to a metal (usually aluminum) profile, which also serves as a radiator.

According to the design of the LED tape, it is distinguished by:

• sealed;
• resistant to dust and moisture;
• poorly protected;
• without protection.

Whenever you choose a device, do not take it away and take it foreseen, under any conditions, it will still work and work. Bathe the tape itself with appropriate rates on late Wednesday.

Now in relation to power and light power. Poznavayki power on a single LED, for the forest and all the specific power on the SL Samata. For a product with 60 diodes per 1 m, the specific power is still 0.2 * 60 = 15 W / m. For a 120-diode tape, reciprocally 30 W / m.

Naturally, the theses of the calculation are valid for Markov products themselves, directed from true LEDs, and not from falsification. But the trick is here, why 90% of the laziness on the lighting of the pazar is directed to the base on the Chinese smd 2835! Osvent tova sell honors gi positionirat kato "premium", kupuvacha's hangers. How can you determine the real “premium” of a commodity or will you “sell” a counterfeit product from a lower capacity?

How do you disassemble the silata on the LED, crawl into the ribbon

Price on the first place. The price for a tape with low power is slightly different from the price for a true product. There is a trace of density on power. Anything that is recognized from the arithmetic, you can count some of the LEDs installed in the ribbon. For yes, send tov, just look at the friendly documentation and squeeze 4 buds on the calculator.

For the experiment, go to the Internet and look at the product. Otidoh on a decently decent site and chose two emissions: “premium” and “economical”. Parviyat e exactly 6 five by -skjp from the second:

1. LED strip smd 2835 120 СW Premium.
2. LED strip smd 2835 120 CW Economy.

smd 2835 120 CW Premium and smd 2835 120 CW Econom

Characteristics on parvia:

• LEDs per 1 m - 120;
• specific power - 8.4 W / m;
• specific light flow - 635 lm / m;
• save voltage - 12 V.

Characteristics for the second:

• LEDs per 1 m - 120;
• specific power - 9.6 W / m;
• specific light flow - 360 lm / m;
• save voltage - 12 V.

We see some kind of tazi premium. Calculating the power for 1 LED: 8.4 / 120 = 0.07 W. Light flux from a single LED: 635/120 = 5.3 lm. Prestignahme ... Tosi "premium" is sgloben on Chinese LEDs with a power of 0.09 W with a bright stream of 8 lm. Osvent tova, for yes, it’s a miracle and work for a long time, designer osigurikha on a diode lek mode. Those significantly reduced the consumption of energy on the current limiting resistors, which, in some ways, brought them to painting on the light stream with one and a half five.

How do togawa beshe vmknato in lentata for economikata? We're sorry. Power per LED: 9.6 / 120 = 0.08 W How can a crystal in a caraha be resourceful developers in housings on smd 2835 LED? The goods are known to the manufacturer itself. We can, of course, assume that you zanayatchiite sa grafted a crystal from smd 3528 into smd 2835 cases or dori in a bad way. Or maybe they just overestimated the power density for attractiveness, but they took it away and counted the stream of light, who knows.

Somehow the Kazakh is in grief, low-quality falsification of friendship from documentation, in some way characterizing it can and will be significantly overpriced. Therefore, the method for calculating disputes and declaring characteristics may not work. Here, we will remain focused on the very top of the price and visual brightness.

Ima and another option: measure the resistance to the current-limiting resistor, calculate the current of it and estimate the current of the current on the LED, turn on the wire (usually 3, in order 5). But this method is the quest for special knowledge and research, and it’s difficult to understand the confusion.

How can we distinguish SMD 2835 from 3528

Ima and a friend of the type of LEDs, which is often se barkat from 2835 - smd 3528. Do not digitize yourself, but also dvata model imat ednakvi size. Regardless of the product, the product is completely different devices and the LED 3528 has a lot of modest characteristics:

1. Power - 0.06 W.
2. Svetlinen flow - 6 lm.
3. Ъglt at a bend of 100 degrees.

For starters, as an object of the device, then, for example, a tape or a lamp with a specific power of 3.6 W / m instead of a 14.4 and a light flux of 360 lm / m instead of 1200.

How can you tell one type of LED from the other? Tova is not difficult, but direct it, ty kato design characteristics for everything from ty sa visible dory with just an eye:

View of smd 3528 and smd 2835 LEDs

Parvo, the crystal on smd 2835 e covers the connection of the area on the hull, for a loan of 3528, the very small circle of the loop. In between, just for the sake of takava malka petna, yglt at the last stop at the last se constraining up to 100 degrees.

Secondly, ty kato smd 2835 ima pon four five on-golyama power, that se heating up more, which means, in some way, che is an effective spread on toplinat. And the roles on the radiator, somehow the Kazakh veche, are playing from the conclusion to the device - they are much better for the tozi type of LEDs.

Such a wide range of LEDs and LED tapes smd 2835.Now you know where it is used, how the characteristics of the imate and how it differs from the product from the similar type.
