LED lamps H4. LED headlight H4

LED H4 lamps are used in two-headlight systems; their main purpose is the headlight of a car. The design provides diodes that perform various tasks. Thanks to this, LED light bulbs in this design are used when organizing low and high beams. You can conduct your own test of different lighting elements or use proven information about the operation of the main types of car lamps.

Design and principle of operation

In addition to a certain number of light-emitting elements, the design provides a cooling system: radiator + fan, as well as an H4 base. As a result, the LED Headlight H4 bulbs are quite massive.

The main thing when choosing a lamp is that its dimensions correspond to the dimensions of its halogen counterparts.

But the main thing is that their dimensions correspond to the dimensions of their halogen counterparts. The diodes are positioned differently than the filaments in a halogen, which provides a slightly different lighting effect.

The principle of operation of LED Headlight lamps is to obtain light energy by converting the electrical equivalent. When the high beam is turned on, all light-emitting elements provided in the design are used.

For low beam, only a portion of the LEDs are used. Accordingly, the main area of ​​application of LED Headlight H4 is the organization of automotive lighting, in particular, low and high beam.

To install instead of halogens, it is important to select the size of the light source as accurately as possible. But today there are optical systems designed specifically for LED lamps.

Types, technical characteristics

The main differences between light sources of the LED Headlight H4 type are: the shape of the product, the type of light-emitting elements, their number and location, as well as the type of cooling system. As for the last of these parameters, there are light bulbs with active and passive heat removal.

Chinese model G9X 2015, passive radiator with flexible ribbon elements

The difference between them is the presence of a fan. The shape of the LED headlight H4 can be different: with 2-3-4 edges, which determines the way the diodes are arranged. There are flat and cylindrical products; in each case, the light-emitting elements are arranged differently, which is influenced by their number and size.

Models with active radiator cooling: this makes it possible to use powerful LEDs to illuminate the road

However, tests show that not all design options for such light sources are equally effective. The closest to real lighting, similar in light boundary to “halogens,” are lamps in which the chips are installed in the same way as the filaments in their halogen counterparts.

The CREE company produces five series of high-power LEDs, different in design and type of crystal used: XR-C, XR-E, XP-C, XP-E and MC-E.

Also, in some models, a so-called curtain is installed on one of the diodes, thanks to which, when the low beam is turned on, a light border of the desired shape is created.

The number of light-emitting elements can be different: from 2 to 18 pieces, and the type is usually represented by the following options: SMD 2323, SMD 5050, CREE (with different parameters). The power varies from 4 W to 50 W, which is determined by the type of diodes used in LED Headlight H4 bulbs and the cooling system. More powerful chips and forced ventilation increase not only the level of load created, but also the cost of such a product.

In addition to the power value, the lighting element in this design is characterized by other parameters:

  • power supply (12/24 V);
  • luminous flux: sufficient for low beam is 1,000 lm, for high beam – 1,500 lm, in addition, LED headlight H4 lamps are capable of providing much higher radiation intensity;
  • type of diodes, usually the manufacturer indicates the brand CREE, SMD, less often the parameters are written, for example, 1512;
  • color temperature – for sources of this design, the normal range is 4,000-6,000 K;
  • degree of protection;
  • temperature range during operation of the LED headlight H

Often, instead of chips from well-known brands (for example, CREE), nameless analogues are installed. You can distinguish a fake by visual signs: the second option is usually characterized by non-standard sizes: larger than the original.

Read more about the pros and cons

Undoubted advantages: long service life, noticeably lower load level with a very bright glow, when compared with halogen lamps. LED light sources do not require care or special maintenance, other than ensuring normal operating conditions. In particular, long-term operation can be achieved by installing an effective heat removal system. Some versions already provide active cooling, but such kits are noticeably more expensive than conventional lamps.

However, there are also disadvantages, for example, changed parameters of the luminous flux created by the headlight optics: the test shows a less pronounced light border, excessively bright light, which may indicate an incorrectly selected lamp. The reason for this lies in the variety of designs of light bulbs, in each of which SMD and CREE diodes are located individually. In addition, LED headlight H4 light sources can have larger dimensions than halogens. This nuance is especially relevant when choosing a lamp to replace a version with a filament.

Criteria for choosing a car lamp based on diodes

The light source must match the radiation intensity so that the high and low beams provide illumination with the parameters required for these optical systems. Diode bulbs are the most economical type of lighting element; accordingly, the power in this case will be less than that of halogen bulbs and other types of analogues.

The electrical characteristics of the power source (current, voltage) are also taken into account; they must correspond to the connection parameters in a particular optical system.

Next, attention is drawn to the way the chips are arranged and their type (CREE, SMD). The test shows that the closest in characteristics is a lamp in which the diodes are installed in the same way as the two filament bodies in a halogen lamp.

The color temperature is also taken into account; this parameter is responsible for the hue of the radiation. Again, the most preferable option can only be determined by doing a practical test using several types of lamps.

Review of light sources from different manufacturers

When choosing an LED lighting element, you should give preference to products from reliable brands, for example, Osram, Philips, Koito. Such products last a very long time and do not raise any questions during maintenance due to the compliance of lighting parameters (brightness level, quality of low beam light edge). A test that has been carried out many times by different users confirms this. Issue price: 500-3,000 rubles.

If we consider the products of MTF and General Electric, then when the headlights are turned on, the brightness level interferes with oncoming and even passing cars while driving on the road. Any test will produce similar results, which is due to the design features of these light bulbs.

As for cheap Chinese products, which usually do not have a name, in this case you cannot count on the compliance of the declared parameters of the light source with the actual characteristics of road lighting. In addition, the test of some light bulbs also reveals differences in the dimensions of the chips, which indicates a counterfeit of the famous CREE analogue.

There is one more feature that confirms that it is better to buy proven products from well-known brands. It lies in the difference between the crystals used in light bulb designs. Thus, reliable structural elements (CREE) are manufactured with high quality; as a result, natural processes of clouding of the crystal occur only after a long period of operation.

H4 diode lamps are installed in headlights. The main feature of such lamps is that they are suitable for both distant and near lighting at the same time.
There is a large selection of h4 lamps on the market. You can choose almost any one, the main thing is that they have an appropriate base. And yet, among the reviews you can find both positive and negative. Let's look at how h4 diode lamps work, what is their difference, how to install and use them correctly.

LED H4 lamps can be both dimmer and brighter than their halogen and xenon counterparts. This indicator depends on the type of LEDs and lamp power. The highest quality ones include epistar, samsung and cree. They are distinguished by excellent performance, warranty and brightness.

For high-quality operation, LED lamps N4 must have a base suitable for power. If its parameters do not correspond, then installing such a lamp is useless. For h4, the following indicators are suitable: 1650 for high beam and 1000 for low beam.

Diode lamp h4 - features

These lamps combine two high-power LEDs at once. The LED for low beam is located at the top, and for high beam it is located at the bottom. The size of the LEDs is important. No matter how strange it may seem, the smaller the diodes, the better. The headlights were initially designed according to the spiral of a halogen lamp. Therefore, the diodes should be close in size to it.

H4 diode lamp – cost

There is a huge variety of such lamps on the market. Chinese industry diligently produces a large assortment. You can find h4 lamps for 1000 rubles and 5000 rubles.
Pay close attention to the characteristics! Often they are indicated incorrectly or completely incorrectly.
Necessary parameters for work:
High beam brightness – 1500 lumens,
Low beam brightness – 1000 lumens,
Power – 17 watts,
The presence of a radiator with a cooling system.
The lamp efficiency should be about 100 lumens per watt.

Diode lamp h4 – brightness

Most often, the brightness in stores is indicated at random. Most often they will tell you the total brightness for both low and high beam. For example, 3000, 3800, 4500 lumens is not the brightness of the high beam, but for both LEDs.
In fact, brightness above 2500 is unrealistic.
Make sure that what you buy is not a Chinese counterfeit. As a rule, Chinese analogues with similar names are much larger in size.

H4 LED car lamps - device

The light bulb consists of the following parts:
Two diodes (for low and high beam)
Fan (located at the end)
Aluminum radiator.

In appearance it resembles a halogen lamp, but headlights for halogen lamps are usually not designed for LEDs. The reason for this is that the spiral area in a halogen lamp is much smaller than an LED. In order for an LED lamp to work correctly, it will need a lens.

Advantages of h4 LED headlights

They are popular for a reason. There are a number of reasons for this. Let's name the main ones:
They consume little electricity. This significantly saves your money and creates much less voltage on the machine's electrical system.
They work for a long time. LEDs have a much longer lifespan than halogen or xenon LEDs. Manufacturers quote figures up to 50 thousand hours. Even if these figures are exaggerated three times, they still exceed analogues.
High resistance to external influences. LEDs are not afraid of moisture and dust. They can also easily withstand even large vibrations, shocks, etc. The reason for this is that they do not have a filament.
The luminous flux is quite large. The declared luminous flux of LED lamps is 1800 – 3600 lumens.
Nice color temperature. LEDs for h4 headlights are those that emit white light. It is as comfortable as possible for the human eye.
Environmental friendliness. These lamps do not contain any dangerous substances such as mercury. Even if the lamp is damaged, it will not harm your health.
The light from LED lamps does not dazzle. This is a very big plus, because if you blind someone coming towards you, you risk getting into an accident.
Lights up quickly. More precisely instantly. Unlike analogues, LEDs do not need time to light up - they light up immediately.

Bottom line

Having considered the main points in the operation of h4 LED lamps for cars, we can summarize the following:
They have a number of undeniable advantages (long service life, pure white light, economy, etc.)
When choosing, you need to carefully ensure that you are not sold a fake.
When connecting, you need to check that all the parameters of the car and the LEDs match so that they work as expected.

H4 LED bulbs are used to replace similar types of halogens in headlights, in which the headlight is created using a lamp with 2 incandescent filaments.

The Netuning online store offers car headlights that really illuminate the road and do not blind other road users.

Characteristics and design

Car headlights are designed for halogen lamps, but many drivers are dissatisfied with the quality of lighting and therefore switch to LEDs. For a long time, there was no point in taking H4 LED bulbs, since they were designed like corn bulbs - there were many diodes on the lamp that shone in different directions. Such lamps did not illuminate the space in front of the car, because their light was directed anywhere but onto the road.

Currently, LED lamps are constantly being modernized, and today there are already 7-8 generation light bulbs on sale. In such light bulbs, LEDs are installed in one row of 3-4 pieces, and the result is an almost complete imitation of an incandescent filament.

The H4 lamp consists of near and far diodes, a fan (not present in all light bulbs) and an aluminum radiator. Structurally, it is similar to halogen, but the latter uses filaments.

Characteristics:

  1. Power: 18-55 W;
  2. Luminous flux: 1800-4500 Lm;
  3. Number of diodes: from 4 per light bulb;
  4. Service life: up to 50,000 hours;
  5. Housing material: aluminum.

When the headlight shines like a spotlight - all the diodes provided by the design work. When low beam is applied, some of the LEDs are turned off, and the luminous flux of the operating LEDs is directed upward by a special screen, and only the upper part of the reflector is used.

Advantages and disadvantages

The advantages of H4 LED lamps include:

  1. Long service life (with proper use and care, the light bulb will last up to 11 years);
  2. Strength;
  3. Instant ignition of LED sources;
  4. High brightness light;
  5. Minimum power consumption.

Disadvantages of lamps with diodes:

  1. Dimensions do not match standard halogen lamps;
  2. High price (compared to halogens).

Criterias of choice

When choosing H4 light bulbs, decide on the purpose of the purchase: car decoration, saving battery energy or improving lighting. Then choose the color of the lamps - LEDs can shine in different shades of white and yellow.

Next, pay attention to the number of lumens. The number of lumens indicates brightness, but unscrupulous sellers may deliberately inflate this parameter. We measure the parameters of light bulbs ourselves and indicate their actual characteristics on the website.

Another nuance is the location of the LEDs. A good light bulb does not have LEDs on all sides and in front - they are located in the optical center of the lamp.

The Netuning store offers branded and high-quality H4 LED lamps for headlights. All equipment comes with a one-year warranty. You can order products online, by phone or at one of our 14 representative offices.

The comfort and safety of driving at night depends entirely on road lighting. Everyone knows that cars using incandescent headlights have less than ideal road illumination. This especially applies to headlights with combined high/low beam, which use a bulb with an H4 socket with two filaments. You can get out of this situation by replacing standard lamps with LED ones, which are not only bright and durable, but also consume significantly less energy.

A new development has appeared in the assortment of the DLED online store - LED lamps with an H4 base with a power of 22 watts. On the sides of this lamp there are two brightest CREE LEDs. Depending on the use of the lamp in low or high beam mode, one or the other LED is used. Due to the different distance between the LEDs and the lamp base, the border of the light changes. The length of the LED crystal matches the length of the filament, which makes the light distribution in the headlight similar to an incandescent lamp, without requiring additional adjustment.

The lamp body is made entirely of aluminum, and a cooler is included for best cooling. However, this fact does not cause concern, since the LED lamp heats up several times less than incandescent lamps. Your car's headlight lenses will become less cloudy in the summer and reduce ice formation in the winter. The kit also includes an electronic control unit responsible for the operation of the cooling cooler, voltage stabilizer and switching between low/high beam modes. The voltage stabilizer compensates for voltage surges in the on-board network; it also ensures the operation of the lamp in both cars and trucks, the voltage in the on-board network of which is 24 volts.

For ease of connection, the control unit is equipped with a standard plug for connecting to the standard car wiring connector. You don't have to cut wires, install additional switches, and you can put back the standard lamps at any time without any problems.

1. Remove the standard lamp from the car headlight

2. Install a new LED lamp instead of the old one

3. Place and secure the control unit in a convenient location

4. Install the cooling cooler on the lamp

5. Connect the lamp and cooler to the control unit

6. Connect the control unit to the standard wiring connector

LED bulbs are brighter than incandescent bulbs and provide better road illumination. The beam of light from diode lamps hits further, illuminating a larger space without blinding drivers of oncoming vehicles.

The color of the LEDs is whiter; this light does not tire the eyes and provides good perception. In addition, LED lamps last several times longer than incandescent lamps and are not sensitive to shocks and vibrations. LEDs require much less energy to operate, therefore, after installing these lamps, the load on the car’s generator will be reduced, and fuel consumption will be lower.

LED bulbsH4 N1- LED designed for organizing head lighting. They use an advanced type of radiator made from aircraft-grade aluminum. It helps to remove heat more effectively and increase service life. The products are a modern alternative to incandescent lamps.

Modern LED bulbsH4 N1- LED They are very popular among car owners - they are reliable, compact and provide bright lighting. When developing the model, the designers managed to reduce the length of the body, improve focusing and greatly increase the efficiency. The lamps can be effectively used as high, low and fog lights.

Key advantages of LED lamps

    • Optimal focusing. This is achieved thanks to the small dimensions of the LEDs and their location, like a filament. As a result, it is possible to achieve excellent illumination and not dazzle oncoming drivers.
    • No ultraviolet violet.
    • High heat dissipation performance. A copper core is laid from the LEDs to the radiator, thanks to which heat is removed in a timely manner and overheating is prevented, increasing the service life of the equipment.
    • Economical. LED lamps heat up less and consume less energy compared to halogen and other analogues.
    • High brightness of light. LED lighting is 3 times more powerful than halogen light sources.
    • Instant ignition. LED lamps do not require additional time to light up.
    • Permitted by law. The traffic police do not fine for the use of LED lamps, as is the case with xenon.
    • Reliability. The lamp can withstand ambient temperatures in the range -50..+80°C.
    • Tightness. LED bulbsH4 N1- LED They are moisture and dust resistant to IP65 class.
    • Ability to withstand shock and vibration loads. The body of the product is non-separable and solid.

The fins are located vertically, they have a special increased area, this allows for more efficient and intensive cooling. Installing an LED lamp is not difficult; it is almost identical to installing a regular standard lighting fixture.
