Recently, LED-lamps have become popular among drivers. They can be used in any optics system, be it interior lighting, headlights, and so on. The popularity of LEDs deserved thanks to a number of advantages that distinguish them from other lighting elements.
LED lamps for car
Advantages of LED lamps
There are several reasons why LED lamps are the best choice for installation in a car:
- LEDs can produce more light per watt of energy compared to any other household lamps. Their efficiency saves electricity and can exceed the average of more than 10 times.
- LED elements work without heating, which distinguishes them from incandescent bulbs, which got their name precisely because of this feature. In some cars with classic devices, plastic is melted, which is located next to the source of illumination.
- LED lamps have a pure white light, which makes them more convenient - such lighting does not distort the perception picture. This affects people outside the car, as LED headlights increase the visibility of the car to other drivers. In addition, for decorative purposes you can buy LEDs of any color.
- LED sources have a longer service life compared to incandescent lamps, which allows for less frequent replacement. LEDs work about 50 times longer than incandescent bulbs and an average of 10 times longer than fluorescent ones.
- They also feature high flask strength, protection from external influences, including vibration and moisture.
- LED sources have a faster turn-on time, which can play a decisive role on the road, allowing you to save the driver and passengers from an accident.
- LED illuminators allow you to change the radiation angle due to optical elements (lenses).
- LED-lamps are completely safe for the environment and the human body - they do not have a harmful effect. They do not poison nature during processing, including mercury free.
- LEDs are much smaller in size than other lamps.

Им не грозит разрыв нити, так как для освещения используются электроды в газонаполненной среде. Они могут использоваться в любом типе освещения, будь то головная оптика или лампы в салоне.
Disadvantages of LED lamps
In addition to the many advantages, LED-lamps have a number of disadvantages that do not allow them to completely replace incandescent and halogen elements:
- The high price, which is explained by the fact that production requires a lot of expensive items. In addition, the creation of such lamps requires sophisticated technological equipment. It is believed that LED sources do not pay for themselves with their lifespan or quality - they are quite expensive.
- If any item breaks down, the LED source cannot be repaired - this distinguishes the LED from other lamps. Thus, if the LED breaks, the entire element must be changed, which requires additional expenses.
- In Russia, most LED-elements are produced contrary to laws and standards. This leads to the fact that in cars there are fires and short circuits, as well as overloading the power supply network. In addition, another violation of the law of sales is the periodic lack of labeling and characteristics on the packaging. This makes it difficult to select the item.
- Most of the LED elements, whose role is to produce white light, have a dip in the spectrum at 480 nm. This leads to the fact that the eye can not respond to the wavelength in a normal way, narrowing the pupil. Thus, an excessive amount of blue light gets into the eyes, which can confuse in the short run and hit the retina in the long run. Experiments on mice allowed us to confirm this assumption. Somehow, some firms have already invented safe lamps.
- LED elements tend to burn out, which leads to a decrease in brightness.
How to choose LED bulbs
First of all, it is necessary to determine what goals are pursued by the purchase of LED-lamps. Some drivers do this in order to decorate the car with decorative colors, others to save battery power, and still others to replace optics less often. Thus, specific LED elements need to be selected depending on the desired properties. Attention should be paid to the packaging, which shows all the characteristics. In addition, the choice may fall on the diodes of a particular color temperature - the LEDs may have a color from yellow to blue, and white is approximately in the middle of the Kelvin range.
LED lights for parking lights (left)
In addition, LED lamps differ in purpose. Some are suitable as parking lights, others as head optics, and still others for interior lighting. Criterias of choice:
- Sphere of use;
- Requirements and wishes;
- Device type;
- Model and manufacturer of the car, which will be installed LED sources.
Appointment of LED lamps in the car:
- Head optics - directional lights, fog lights for low and high beam;
- Rear lights;
- Side lights;
- Parking lights;
- Lighting in the cabin, as well as the trunk.
Selection of LED lamps depending on the type
Low beam bulbs
This type of optics most often has an H7 base. The LED must be on the top of the element. Light is reflected from a special surface on the headlamp, getting the right direction. To determine the luminous flux of such a lamp, you need to find its documentation with characteristics. The required properties for the low-beam diode are as follows:
- Power from 12 watts;
- Luminous flux from 1000 Lm (the minimum acceptable figure is possible only when using high-quality diodes);
- A cooling radiator is also required. Its absence is allowed, if according to the factory specifications the cooling of the lamp is not required due to its small size.
LED headlights
There are several reasons why a LED lamp may not be suitable for use. First, the design of the element may not correspond to the free space near the socket in the car, which will interfere with its use. Secondly, there may be a mismatch between the optical design of the element and the reflector system. Thus, the low beam lamp, like any other, must be chosen in accordance with the car.
Headlight and dipped beam
Type H4 LEDs can be used for two assignments simultaneously. A design feature of the diode is the presence of two sources of light - dipped (located in the upper part) and far (in the lower part). When choosing between several options, it is recommended to look in the direction of the one that has the smallest size, since the element is designed for the size of a halogen lamp.
As for the characteristics, for a high-beam diode, they are:
- Brightness from 1500 Lm;
- Power from 17 watts;
- Radiator with cooling system.
For the low-beam diode, the requirements are the same as the H7 type. It should be noted that if there is only one brightness parameter on the package, it is total for two sources. In addition, all values above 2500 per element are most often exaggerated.
Front brake lamps and overall dimensions
The most popular format is W5W. The range of these lamps is very wide - from the dimest lamps per 100 Lm to fairly bright ones, at 500. As practice shows, even indicators of 1-2 Watts and 50-100 Lm are sufficient - too much power quickly consumes the lamp life without giving anything in return.
Rear brake light lamps and dimensions
This type of optics standard is P21. Now there are many options for the device marker lights - in addition to the usual can be found with 3, 14 and even 27 diodes. The power and brightness of such lamps depends on the number of chips. In the budget lamps installed no more than 3 chips, which is not enough to ensure all the LEDs - they will shine dimly.

Headlight Bulbs
Elements in this optics allow the car to be more noticeable in the fog, as well as during snow or rain. In addition, they significantly increase the visibility for the owner of the car, also allowing him to avoid an emergency. To fog LEDs

adom.ru impose less quality requirements - it is usually lower.
The most popular bases are H8 and H11. Despite the relatively low requirements for brightness, it is not recommended to use lamps with an indicator of less than 900 Lm, because otherwise they will become only decorative elements and will not cope with complicated weather conditions. The power of such elements must be at least 10 watts.

High Beam Lamps
This type of optics is a separate element for lighting at a great distance. The standard of the cap is H1. In terms of operation for the intended purpose, this type of LED-lamps has no advantages over halogen lamps, therefore, their installation may be impractical due to the relatively high cost.
LED high beam
The requirements for high-beam diodes are as follows:
- Power from 17 watts;
- Brightness from 1500 Lm;
- Mandatory presence of a cooling radiator.
It is necessary to select elements according to the size of the headlamp.
Interior lamps
Most often, such lighting devices are used for tuning, as they give an unusual light. It should be borne in mind that the constant impact on the eyes of low-quality LED-lamps can cause unpleasant consequences. There are several types of these devices:
- Lamps for installation in the factory socket. Replaced without problems, because they have the same connection. Are more compact.
- Larger LED lamps, which consist of several elements. They are also designed for installation in the factory socket, but because of their size I can not fit there - you have to modify the box.
- Rectangular diode array. Such optics, as a rule, almost never fit into the factory box and require its complete replacement.
Total
LED lamps have many advantages that make them a modern source of lighting. In addition, the shortcomings will soon be corrected by engineers, which will allow LED-devices to crowd out the rest. Already, these lamps can be installed as any element of optics. When installing, it is first recommended to replace the side lights - this will give an idea of the process and prevent errors on more complex and significant headlights.
