The main parameters of LED automobile lights, what they mean?

LED automotive lamps have long been part of our lives, they are actively using the drivers, because performance is what sets them against other types of automobile light.

If you are planning to replace halogen avtolampy more efficient and advanced LED, then before you buy should definitely examine in more detail all the characteristics of such devices. This will allow it to buy those whose parameters are fully consistent with your vehicle and operating conditions. After all, the quality of Avtosvet and level of illumination of the road in the dark depends on the safety of the driver.

Basic characteristics of LEDs

If you're buying galogenok've always had to first look at their wattage to understand how bright will shine one or the other lamp. That is the case with LEDs, this figure is not so important.

At the LEDs Watts indicated on the packaging, do not speak of the lamp brightness, the level of electricity consumed per unit of time, usually an hour. Please note that if you compare incandescent bulbs with LED counterparts, that at the same brightness, power consumption in the LED will be several times lower. That is why they are becoming popular because they reduce power consumption, giving no halogen on the light level. As for the brightness of LED lights, the main unit in which the measurement of the brightness of the light, is the lumen.

What is measured in lumens, and what does this option?

Lumens indicate the value of the luminous flux distributed any light source.

For example, a simple halogen lamp 80 watt creates a luminous flux of about 1,000 lumens. A LED in order to achieve the same luminous flux of force requires much less power, so they are much more economical.

It should also be said that the lumens indicate how much light gives automotive lamp. That is, the higher the lumens, the brighter the light shines. However, it should be borne in mind that the brightness and lumens indicator for different lamps will still be different because the lumen is not an absolute indicator. It is important when choosing to take into account other parameters: color temperature, light intensity, brightness and intensity.

Keep in mind that, in determining lumens takes all the luminous flux. And at the same lowers efficiency of focusing of the lens or reflector automobile headlights. It is because it is impossible to assess the lamp brightness to rely only on the indicator lumen, it does not reflect the intensity of the beam and absorbs all light, including diffused much useless. For example, a wide and well focused light beam can have the same value of lumens, but their total brightness is different.

What does the luxury option in the LED lamps

Suite characterizes the level of illumination. It shows how to be illuminated by a small surface whose area is one square. m. in contact with it light flux of 1 lumen. To make it clearer, imagine that at the road section area of ​​1 sq. m. directed light beam 100 lumens, in this case, the illumination will be equal to 100 lux. Now take the same flow of 100 lumen, but directs it to the portion 10 sq. . M, natural light is below-it will be only 10 lux

.

Lighting-is a value directly proportional to such indicators as intensity. In this case, if you remove the bulb from the surface-illuminance falls, and when approaching-is growing. Normalized generally vertical light component, i.e. distribution of the luminous flux in the horizontal plane.

What is the significance for the LED indicator is Kelvin?

Usually, the classic incandescent lamps give smooth warm light yellowish. But LEDs can have a different color of light, there is available a wide range of colors from purple and red, cool white. And to determine what color light will shine you can have in the store, on the labeling. This is where you come in handy this parameter, as color temperature, it is precisely measured in Kelvin.

Kelvin-is a characteristic of any source of light, it determines not only the color of light, but also its color tone (eg, cold, warm or neutral). From physics all know that sunlight-a combination of radiation with different wavelengths. Connecting, different light rays can give a different color of light, the same holds for any other light source.

Note that the color temperature does not characterize the spectrum of rays that are part of the radiation coming from the LED lamp. This option reflects the way the human eye perceives the color of light that particular bulb.

As for Avtosvet, the pattern here is quite simple: the lower the number, the more light will shine yellow. In standard halogen auto lamp color temperature is typically 2700-3500 K. That is, you need an LED lamp with a similar warm yellowish glow, then choose when buying a lamp, on the packaging which also contains a similar color temperature

.

To determine the exact colors used special Kelvin temperature scale. According to which:

2700-3000K-this figure corresponds to a warm and soft light, which is dominated by red spectrum rays

.

4000-4200K-this figure corresponds to the cold light, and the light is distributed evenly across the spectrum

.

5200-6500K-this figure corresponds to the light of day, while it is dominated by the rays of the blue part of the spectrum

.

8000-25000K-this corresponds to a range of UV

.
