For your information! If it is necessary to cut the LED strip in accordance with the conditions of installation work, it can be cut. To do this, there are cutting lines on the outer surface that divide the tape into segments. Soldering points are provided on the cutting line, through which the product is connected to the power supply.

Appearance of the tape with division into segments and a cut line

Depending on the type of coating, LED strips come in different degrees of protection (IP code), which are regulated by GOST 14254-2015 (IEC 60529:2013) “Degrees of protection provided by shells (IP code).”

Products with the highest degree of protection IP65 - IP68 can be used in damp and damp areas, as well as directly in water to illuminate aquariums and swimming pools.

The operating voltage for such artificial lighting sources is of two types: 12 and 24 Volts direct current. To control their operation, special devices are used that allow you to regulate the intensity of the light flux - dimmers.

LED strip at work

Due to the fairly high electrical power, SMD 5730 series tapes generate a significant amount of heat during use. Because of this, the installation of such products must be carried out using an aluminum profile, which allows for heat dissipation and thereby extends the life of the LEDs.

Based on the LED strip of the SMD 5730 series, modules of various shapes and sizes are manufactured, used in the manufacture of lamps of various sizes and configurations.

LED strips of the SMD 5730 series are an individual style in home interior design and high-quality indicators of artificial lighting.

📋 Take the test and make the right choice

One of the main characteristics that you should pay attention to when comparing LEDs, be it SMD 5050, 5630, 5730, 3528, 7020 or any other model, is the dimensions. The aspect ratio of the LED 5630 is 5.6 by 3 mm; for LED 5730 - 5.7 by 3 mm. 5630 has four pins, 5730 has two.

Another significant difference between the 5730 and the 5630 (a later version of SMD from the previous one) is the luminous efficiency of the radiation. Manufacturers took into account the shortcomings of the 5630 chip when developing the 5730 matrix and improved some aspects. In particular, the body and contact pad of the crystal were reduced, the supply of the required current was reduced, and the indicators of luminous flux, power and temperature were maintained. The combination of actions made it possible to increase energy efficiency and service life.

Characteristics

When SMD 5630 first appeared on the market, the event was marked almost new era in the history of LED devices. Today, much more technologically advanced devices are being produced, because the industry is not standing still, but is developing rapidly. Despite this, the 5630 diode is still in play. Below are the main characteristics:

• power - from 0.5 to 1.1 W;
• forward voltage- from 3 to 3.8 V;
• operating current - 0.15 A;
• pulse current - up to 0.4 A;
• luminous flux - from 40 to 60 lm;
• operating temperature - from -25 to +85°C;
• dispersion angle - 120°;
• color rendering index - from 80 to 90 Ra;
• color temperature - warm white (from 2700 to 3500 K), neutral white (from 3500 to 5000 K), cool white (from 5000 to 6400 K).

LED 5730 - improved version. In general, the parameters have not changed much; the differences from the LED 5630 can be seen from the data in the table.

If you are going to assemble a light bulb or LED strip 5630/5730 yourself, remember: the diodes must be fixed to an aluminum substrate and equipped with a cooling system. This removes the heat generated by the crystals and ensures long, uninterrupted operation.

Types of LEDs

The SMD 5630 has much fewer modifications than the SMD 5730, and this is another important difference. The 5730 LED diode has at least 3 design options:

1. SMD 5730-05

   The power consumption is 0.5 W, the maximum permissible current is 0.18 A. The diode spends almost all the power on the luminous flux. In pulsed mode, the current amplitude can reach 0.04 A and create a luminous flux of 45 lm.

2. SMD 5730-1

   The maximum operating current reaches 350 A, in pulse mode - up to 800 A at a voltage of 3.2 V, provides a luminous flux of 110 lm, power consumption - 1.1 W. The crystal can withstand temperatures up to 130°C, operating temperatures range from -40 to +65°C.

3. SMD 5730-01

   With standard characteristics, the LED demonstrates maximum luminous flux efficiency of 158 lm/W.

Regardless of the type, using the 5630 and 5730 LEDs you can organize decorative and basic lighting in your home or office space, on an industrial site or large open area. LED-based equipment is used for various purposes: for designing advertising objects, zoning premises, tuning cars, manufacturing spotlights and street lamps.

Results

SMD 5630 and 5730 not only do not lose their positions, but maintain them year after year. What is the secret of the trust shown by amateurs and professionals? Compactness, high power, wide range of available operating voltages, increased light output, low power consumption, environmentally friendly diodes.

LED designs based on LED 5630 and 5730 are easy to install, energy efficient and represent a worthy alternative fluorescent, halogen, neon elements, incandescent lamps and other common devices.

However, consumers should take into account the specifics of these chips: in particular, the fact that they cannot be installed directly on furniture. There is a high risk of overheating (this exists with all LEDs, but especially with SMD 5630 and 5730). LED strips 5630, 5730 should be mounted exclusively together with an aluminum profile, the price of which is often comparable to the cost of the product or even exceeds it.

It is also necessary to provide an additional cooling system, otherwise the LEDs may soon fade after use or even fail due to thermal destruction of the crystals.

We advise you to focus on world-famous manufacturers and not be fooled by budget analogues from unverified sites. The Novolampa store has a huge selection: the sections feature products from well-known companies. If you doubt the reliability of the company before purchasing, want to get general advice or clarify details, request a call back. Novolampa store managers will contact you and answer any questions on the topic.

SMD 5730 and 5630 LEDs are among the most popular currently. They are ultra-bright medium-power diodes and have a good combination of size, power and luminous flux. Thanks to the development of technology, in 2015 other modifications began to be produced in the standard SMD 5730 package, which differ greatly in parameters and characteristics from the most common model. By appearance They are practically indistinguishable except by a specialist. Such LEDs are produced only by well-known manufacturers, and are rare, only in expensive LED equipment due to their rather high price. IN ordinary lamp You won't find them made in China.

• Models with two crystals are marked as 5730-1, the rated power is 1 Watt.
• Models with an improved crystal providing up to 158 Lumens per Watt.

The most powerful are considered. Do not forget that you will need a radiator for cooling, which can be an aluminum profile.

Real power of Chinese LEDs

90% of Chinese products, for example on the Aliexpress bazaar, are made with low-power diodes, which are much weaker than branded ones. Branded ones are produced by Samsung, LG, Philips and others. The Chinese actively use this, specifying parameters as if Samsung were installed there. After the purchase, it turns out that the brightness and power are 3-4 times lower than what the seller promised.

It turns out that the Chinese 5630 (5730) is 0.15W weaker than the branded 5050 by 0.2W. Be careful when choosing a product.

Main characteristics of SMD 5730

Compared to SMD 5730, and considered obsolete, they require several times more. Often in describing the parameters (datasheet) of LEDs, I use branded LEDs from Philips, Samsung, Osram. To compile these characteristics, the parameters of branded Chinese production Honglitronic are used, which are not inferior in parameters to European brands.

If you are going to buy diodes, you should be careful. The Chinese produce diodes with a power of 0.15-0.2 Watts in such a package, giving 80 Lumens per Watt. Visually, they are no different from 0.5 W LEDs. If you are lured by a low price, then they may well turn out to be fake. Even after the purchase, it is difficult to prove the fact of fraud, especially if you buy in China, for example on Aliexpress. Making a return will also be expensive and time-consuming, especially since they will happily pretend that they lost the parcel.

Detailed technical characteristics of SMD 5730

What are SMD LEDs? Surface Mounted Device – radioelements that do not have additional mounting connections. They are attached directly to the surface of the circuit board.

This type of ultra-bright LED is widely used in lighting designs. Due to the absence of a housing, the installation density increases and the weight of the final structure is significantly reduced.

Explanation of LED markings

Consider the markings using the example of an SMD 3528 warm white light matrix.

LED-WW-SMD3528

• LED – light-emitting diode;
• WW – warm white – warm white;
• SMD – surface mount diode;
• 3528 – matrix dimensions.

Many manufacturers try to uniqueize their product with various tricks. This is how the 5636, 5736 series appear. Their characteristics are completely identical to the basic models, and the last number indicates only minor changes in the standard size.

Technical characteristics of SMD 3528 (datasheet)

SMD 3528 is a single-chip matrix with low current consumption and relatively low brightness. But precisely because of this, you can design any backlight without worrying about additional heat removal. This assembly is used in night lighting strips, in lighting systems for advertising lightboxes, and illuminated signs.

In the (RGB) version, three crystals are used in the matrix.

LED type	Glow color	Size, mm	Luminous flux, Lm	Angle, degrees	Current, mA	Voltage, V
LED-WW-SMD3528	White warm	3.5 x 2.8	4,5-5,0	120-140	20	2,8-3,2
LED-CW-SMD3528	White
LED-B-SMD3528	Blue		0,6-0,85
LED-G-SMD3528	Green		2,8-3,5

Technical characteristics of SMD 5050 (datasheet)

SMD 5050 – three-crystal matrix. The power of a 5050 LED is proportional to three 3528 matrices placed in one housing. 5050 is used in surface mount systems where increased backlight brightness is required with a limited light emitter area.

LED type	Glow color	Size, mm	Luminous flux, Lm	Angle, degrees	Current, mA	Voltage, V

Comparison tables of parameters

General table of technical characteristics 3528, 5050, 5630, 5730:

Comparison table of technical characteristics 3528, 5050, 5630, 5730

The type of LED is distinguished by crystal structure and color:

The exception is LEDs with three crystals on an LED matrix.

A three-chip SMD matrix, for example, in the 5050 series, has three anodes and three cathodes. It connects as three independent elements. For the RGB model 5050, the characteristics in the datasheet are written for each diode, since they have various parameters energy consumption.

LEDs 5050 - connection diagram

Such connection requirements are due to the fact that even absolutely identical crystals will have differences in the supply current and connecting without a current limiter will simply damage one of them.

REMEMBER!

1. It is not recommended to connect any LED models to a power source without a resistor. When using one resistor, only serial connection one type of LED.
2. In the case of using three-crystal diodes, each channel is connected through a separate resistor and connected to the same diode in the next module.
3. Do not connect LEDs with different load characteristics. In simple words Do not connect 3528 and 5050 together.
4. It is strictly contraindicated to use resistors with a resistance less than the nominal value. This will increase the load current of the LED and shorten its service life.

Some of the brightest and most powerful LED strips are models based on SMD 5630 and SMD 5730 diodes. They are not as widespread as their more popular counterparts SMD 3528 and SMD 5050.

Due to their high power, they can only be mounted using an aluminum profile. Otherwise, in the absence of a heat sink, due to overheating, the service life of such diodes will be very short.

Explanation of the name

The names of the SMD 5630 and 5730 strips indicate the dimensions of the LED housings, and not their technical data, as some people think.

SMD stands for “surface mounted device”. Which, translated into Russian, means a thing, a device, an element mounted on a surface, that is, a tape backing.

The four numbers after the abbreviation are the dimensions (length and width) of the LED housing mounted on the substrate.

Moreover, the manufacturer can mount any LED crystal into this housing, from the most powerful to the weakest. Hence the different characteristics of models that seem to be identical in name.

What is the difference and how to distinguish an SMD 5630 LED strip from an SMD 5730?
SMD 5730 is a newer LED model. And the main external difference is the physical dimensions.

• length 5.7mm (5730) and respectively 5.6mm (5630)

• width 3.0mm

And don’t be confused, 5.7mm is the length including the leads (legs). The actual size of the case itself, where the crystal is soldered, is only 4.8 mm!

The model 5630 has even a little more - 5.3mm. Both have the same width - 3.0mm.

However, with the reduction of the housing in the 5730 product, the power, luminous flux, and heating temperature remained at the same level. For factory-quality branded products, the power is 0.5 W and the temperature is 80 degrees.

Also, the SMD5730 has reduced power consumption - 0.14A, instead of 0.15A for the SMD5630. True, the tension has increased. LED Specifications:

Thanks to these changes, SMD 5730 LED strips are more efficient and have a longer lifespan.

Belt power

To find out the power of the entire belt, refer to its labeling. If it is missing, just count the number of LEDs in one meter.

As mentioned above, in original branded products the power of one LED should be approximately 0.5W.

However, most often, in our stores we come across Chinese varieties that are far from achieving such indicators.

Of course, they are much cheaper than the original (1.5-2 times), but the power of the diode in such a tape is at most 0.15 W. Moreover, such indicators are even more or less acceptable.

But it’s better to avoid models with P=0.09W. The maximum they can produce is 360Lm per meter segment.

In this light, best choice will buy an SMD 5050 LED strip, not this fake. Although the difference in the originals is of course immediately noticeable even to the eye.

Of course, the total power of the strip directly depends on the number of LEDs on one meter of substrate. Here is a comparative table of types of LED strips and their technical characteristics (power in watts):
These indicators are not the only correct ones that all manufacturers adhere to. However, for the most part, the capacities given in the plate are used.

Having calculated the backlight power on 5630 and 5730 diodes, you can safely select a power supply for them. How to choose it correctly without making mistakes can be found in the detailed article "".

Light flow

In addition to power, cheap diodes in 5630 and 5730 strips also have a much lower luminous flux. In Chinese models it reaches 7-12 lumens, but in branded ones it reaches 40 lumens.

Comparison table of light fluxes (in lumens) of SMD LED strips 2835,3528,5050,5630,5730:

As you can see, a high-quality SMD 3528 can be comparable in performance to the seemingly so powerful and bright 5630. Therefore, always pay attention to the manufacturer of strips and LEDs.

Some of the most branded ones are Korean Samsung and European Phillips.

The data on the label applies to white neutral light. In general, SMD 5630, 5730 can be in three different “colors”:

• WW - warm white from 2700 to 3000K

• NW - neutral white from 3500 to 4500K

• CW - cool white from 6000 to 6500K

Choose a warmer color as the main lighting in your home. Otherwise, the light will be like in an operating room or a morgue.

Cool white is acceptable only as local decorative lighting.

If you have a monochrome version of the tape, not RGB, then you can connect it directly to the power supply. There is no need to purchase any controllers.

If you want to regulate and control the light level, buy an additional dimmer.

Such bright and powerful tapes as SMD 5630, 5730 are best connected on both sides. It is for this purpose that the wire leads are made on both sides on the bobbins.

And not, as some people believe, to extend and solder the next 5 meters to them.

To increase the length of the backlight, the second segment (after 5m) is connected only in parallel, and nothing else.

IN otherwise Such current will flow along the paths that the contacts at the connections may burn out.

Keep in mind that sellers on Aliexpress have 90% probability of indicators that differ from those indicated in the table above. And always not for the better.

Characteristics are simply overestimated without taking into account actual data.

Installation of LED strips SMD 5630, 5730

Such powerful tapes can only be mounted using an aluminum profile. This scares many people off, since the cost of the profile itself is often comparable or even higher than the price of the LED strip.

Some take risks and stick it directly onto furniture or use cheap plastic ones for this. cable channels. You shouldn't do this.

At first, everything will burn and shine properly, without any complaints. However, LEDs will heat up over 80 degrees, gradually degrade, and as a result, lose their original brightness.

Most manufacturers, when indicating warranty periods for LED strips (of any brand), mean that during this period the backlight will shine properly with 100% brightness.

When this period expires, the tape will not go out, but will simply lose at least a third of the lumens of its original characteristics. If overheated, this period is reduced by 2-3 times.

This primarily applies to sealed tapes with protection IP65.68. Not only are they coated with silicone, but the lack of heat dissipation in the form of an aluminum profile will significantly worsen the overall picture.

Is it possible to somehow get out of the situation if the issue is not the cost of the aluminum profile, but the impossibility of its installation and placement? For example, it does not fit the design in any way or spoils the entire appearance of the lighting.

The only option in this case is to reduce the power and sacrifice illumination.

Your task is to ensure that the total power of the LED strip is not more than 10W per 1 meter.

This can be done in two ways:

• artificially reduce the voltage on the power supply

For this purpose there is an ADJ regulator. But whether its adjustment parameters are enough can only be checked experimentally.
