Car lamps T10. LED car lamps t10 w5w

W5W LED lamps represent a separate group of lighting devices, which is intended for installation in a car (headlights, interior, etc.). These are compact light sources that are characterized by very high radiation intensity and are not overly complex in design. Their scope of application is quite wide, however, the main direction of use can be identified - tuning of various vehicles.

Operating principle and features of use

Such light bulbs are used in various components of automobiles and motorcycles. Their main task is to modernize the existing lighting system, increase its functionality, and, accordingly, efficiency. W5W sources can be installed in the passenger compartment, trunk, and are used to illuminate license plates and side panels.

But more often they are used when organizing the side lighting of a vehicle, in rear and cornering headlights.

W5W light bulbs also have another name - baseless, which is explained by the design features. So, unlike the usual modifications of LED light sources with a standard holder, the versions in question are equipped with a plastic two-pin T10 type connector.

Depending on the design, the configuration of the light source itself may change (the number of diodes, their location). There are models with circular and longitudinal installation of emitters.

Various shapes with w5w base

The operating principle of any LED lamp is based on the conversion of electrical energy into the equivalent of light. This process is realized by passing current through a semiconductor p-n junction.

Low-power lighting elements usually use a resistor, which acts as a limiter, but does not help stabilize the operation.

In reality, as well as schematically, the W5W lighting element with a T10 holder looks like this:

The quality of operation of such light sources directly depends on their design. The longest-lasting versions are those with a current stabilizer, which ensures more stable operation of the lamp, eliminating increased heating.

Characteristics of W5W light sources

Diode lamps with T10 holder differ in several main parameters:

1. Power. The range is represented by models with different load levels, but almost all of them are characterized by low power consumption (no more than 10 W).
2. The supply voltage can vary from 9 to 24 V.
3. The number and type of emitters is determined by the design. Both parameters affect the quality of light.
4. Light flow. The more diodes are provided, as well as the more powerful each of them, the more intense the radiation will be.
5. Holder type – T10 (regardless of the light bulb version).
6. Dimensions.
7. The shape of the light source is determined by the number of diodes. For example, there are the simplest models with one emitter; they are equipped with a transparent diffuser and externally resemble an incandescent lamp of this type. And there are also more powerful versions in which the diodes are installed in a longitudinal or ring manner.
8. Lighting color depends on the intended purpose of the light source. Functional lighting is organized using single-color light bulbs with a white glow, and T10 decorative lighting elements are presented in a wide selection of shades (green, red, orange, etc.).

The set of technical characteristics determines the level of efficiency of the lamp, and therefore will affect the cost of the product. The simplest designs are offered at the most affordable prices.

For example, a W5W light bulb model with a T10 holder, equipped with just one low-power diode, can cost several tens of rubles, while the most functional versions are offered many times more expensive.

Main pros and cons

W5W T10 type bulbs have many advantages:

• high work intensity due to the use of diode emitters in the design;
• efficiency, due to the minimum power level (several watts);
• long-term operation, much longer than all existing analogues;
• minimal energy consumption reduces the load on the car battery;
• a large selection of designs that differ in basic parameters, as well as in the shade of lighting;
• increased strength characteristics, which makes T10 light bulbs resistant to mechanical damage and vibrations.

Such lighting elements have significantly fewer disadvantages. The most significant of them:

1. Quite a high cost, which is offset by long-term operation, since the light source will quickly pay for itself, especially if the car lighting works regularly and for a long time.
2. Some models use a current limiter (resistor) instead of the required stabilizer (driver).

As you can see, T10 LED lamps are gradually conquering the market, despite the relatively high cost.

Selection options

The main task of the vehicle owner is to determine the node where the light source needs to be installed. Based on this, the desired design is selected, because W5W light bulbs are available in a wide range of design options. Next, the required intensity of the light flux is determined, which will be affected by the intended purpose of the light source.

This parameter also depends on the power of the diodes, their type and quantity. Then a model with a suitable shade of lighting is selected.

The holder type for W5W bulbs is always the same - T10. We must not forget about the brand of the product, since the duration of operation may depend on this. This state of affairs is explained by the degradation of the crystal, which means that the intensity of the light flux, after a certain period of time, will be lower.

Thus, when choosing an LED light source, you need to simultaneously take into account a number of parameters (almost all the main ones indicated by the manufacturer). Not all light bulbs of this type are offered at a high price. However, you should not pay attention to the cheapest versions, since in this case there is a risk of purchasing low-quality crystals. The most famous and reliable manufacturers: Osram, Philips.

Red, hot, yours. This is exactly the slogan the seller could have used if he had sold these light bulbs in 2014 :-)
Next, about everything in order, T10 lamp base. There are 3 colors to choose from: White, Blue, Red. In this review there will be red lamps.
The declared power is 1.8 W, you can bet whether the real power corresponds to the declared one.
Anyone who has placed a bid, or is simply interested, please go to cat.

The bulbs were ordered on July 2 and arrived at the post office on July 16. Despite the promotional price and free delivery, the tracking number was tracked throughout the entire journey.

Let's take a closer look at what this light bulb is.


And it represents the following: a case with a diameter of 11.5 mm and a length of 37.4 mm.




There are 8 LEDs on the four sides of the case, two on each of the four cardinal directions, and two LEDs on the front end, under the convex lens, 10 in total.






Also on the body are fins similar to radiators, although they are very small, so they serve more of a decorative function than improve cooling.


On the light bulb connector, in the middle, between the contacts, there are 10 SMD resistors of size 0805, with a nominal value of 1.3 kOhm, 5 pieces on each side.


The textolite with contacts and resistors fits into the lower end of the light bulb body and is covered with a rubber plug.


Having pulled it out, we will contemplate two more resistors, but this time 1812, on one side 51 Ohms, on the other 27 Ohms.




You can also see that in the depths of the case, a board with base contacts and resistors is soldered to the board from which the LEDs are already soldered.

It's time to connect the LEDs to power and see if the declared power corresponds to the real one.




So, the voltage is 12.1 volts (which is even lower than the voltage of a charged battery), the current consumption... an exciting moment for those who made bets... so the current consumption is 0.16 A, which already corresponds to a power of 1.9 W.


Let's raise the voltage to 14 volts, and what do we see, but we see a current of 0.2 A, and accordingly a power of 2.8 W.


Let's be realistic, in a car with a working battery and a normally working generator, the voltage will always be more than 12 volts. So we can say that the light bulbs not only correspond, but are also more powerful than stated (or is it wrong to say that?).

But not everything is so smooth. Just 40 seconds after turning on, the temperature of the light bulb rose to 50 degrees, and the temperature of the resistors to 85. The glowing LED may introduce an error in the measurement with an infrared thermometer, then the temperature is really high, since holding your finger on the surface of the light bulb for a long time is already very, very difficult comfortable, but with resistors it’s not possible at all.

Well, in conclusion, let’s compare the brightness with a regular double-spiral car lamp, the filament power of which corresponds to 21W and 5W. All photographs were taken with exactly the same parameters, in the camera’s manual mode.

From top to bottom: Spiral at 21W, Spiral at 5W, LED lamp at a voltage of 14 volts. As we can see from the photographs, although the power of the LED lamp corresponds to the declared one, the brightness cannot be compared even with a 5W incandescent lamp. You can draw your own conclusions.

Well, I say goodbye to you, until new reviews...
