What light is better for. Warm or cold light

What is the light brighter, warm white or cold white? This is a frequent question in LEDs.
The answer to this question is one, the cold white is definitely brighter with the same power on an identical model of the LED. What is due to this effect, everything is quite simple, the main crystal emitting light in all models (regardless of the type of glow) is the same.

The essence of obtaining different heat of the glow in the future transformation of the radiation of the crystal to the familiar light is enclosed in the LED component, called the phosphor. Actually phosphor and gives different heat of the glow depending on its composition.

The simplest transformation of light by phosphor occurs when it is obtained by cold white, because All LEDs initially give blue light, and the cold white is close to blue. Next, there is a complication of the composition of the luminofore and, accordingly, a more complex transformation, which causes a slight decrease in the output luminosity.

But, based on the practice for household needs, the neutral white is more like, for residential premises warm white, and cold white to illuminate public places.

Do not assume that the warm white shines worse than the cold white, it is not. Note the difference in brightness, the human eye will not be able, it is possible only with the use of special equipment. It is just necessary when choosing a color temperature of the lamp, consider the estimated place of its use and purpose. We touched upon this topic to another.

Each designer is well known this rule. If you create the design of the apartment project or at home, then definitely consider as much factors as possible. As for lighting in the interior, he is always given a primary role. After all, it is the light that can inhale life in the idea of \u200b\u200bthe designer. It is he who emphasizes the most important details in the interior design.

Not so long ago, only incandescent lamps could be seen in residential premises, which radiated the usual yellow color. The illumination was made to vary the focus of light and brightness. Now everything is wrong.

Energy-saving lamps appeared, which opened new opportunities before designers. They can now afford to add to everything variation with the color of the glow of lamps. And therefore, for example, when you cross the threshold of an electrical store, you cannot not see that the light from different light bulbs is different color. Well, what color to give preference?

What varieties of lamps exist

Modern light sources are customary to divide the shape of the flask, the principle of operation and efficiency. However, it is important for us to determine which light is provided by light bulbs. And therefore, when buying light bulbs, you need to ask the seller the index of their color reproduction.

This is an important indicator. It depends on it whether the interior colors in artificial lighting will be pleasant and adequately.

The color rendition index is denoted by RA letters. So that the indoors were normal lighting, the index should be 80-90, and even better ideal - 90-100. In this case, the light may be cold or warm. And it does not depend on the index. And here you need to take into account the place and specifics of using lamps.

Color of glow energy Saving Lamps It is characterized by the so-called color temperature. Kelvin (K) is a unit of measuring color temperature. The lower the value of the parameter, the color of the glow is closer to the red. What he is higher - the closer to the blue.

Currently, specialists allocate three main colors. Warm white light - 2700 K. Natural white light - 4200 K. Cold white light - 6000 K or 6400 K.

What is the difference in cold and warm light

Experience shows that the most attractive person considers cold white light. Probably because it gives greater illumination.

Light has the ability to drown or emphasize any shades in the interior. These properties have found wide use of designers. For example, it is well known that warm light is able to strengthen the color of the interior details that are painted in warm tones.

Halogenic lamps are considered warm. However, they are radiation, which is closer to the natural light of the shade. That is why they almost do not distort colors. Such lamps are recommended to be placed near the mirrors and in the bathrooms. After all, they make the correct color of the skin.

Unit of measurement - Celvin (K). The lower the value of this value, the more yellow will be the light. Lighting from a light bulb having a high flower temperature will be slightly bluish. Most often there are three main lights of lighting: white warm light - 2700-3500 K. Neutral or natural white light - 3500-5000 K. Cold white light - 5000-5400 K.

The warm light in the interior of the lamp with a warm spectrum is used by designers to increase the color saturation of the interior of thermal tones. Cold shades, on the contrary, will become less noticeable. Blue and green colors will be distorted: this is due to the fact that there are no rays of the corresponding spectrum in the light of such a lamp. With such illumination, cool tones are changed as follows: it may seem greenish; 🎨in will become black; Blue will look like black; 🎨Fiolet can be confused with red.

All light sources used today are characterized by several symptoms: actions. The following types of light sources can be distinguished: LED, luminescent, halogen, as well as all known incandescent bulbs. 📌form flasks. The most common types of flasks are pear-like, spherical, tubular, in the form of fungus and so-called "SPOTS". 📌kpd. The highest indicator today have LED lamps. Cost. The cheapest light sources are incandescent lamps, the most expensive - LED. Nevertheless, the latter are much more environmentally friendly and consumed much less electricity.

As if modern manufacturers with the most advanced technologies neither tried at least a little closer to the lamps and others artificial sources Light to this ideal, so far no lighting device can compare with it, and any light bulb, possessing its color, forms its type of lighting. That is why, depending on what room, the light is selected, in which it is supposed to live in comfort or focus, as well as taking into account personal preferences, it should be chosen as a cold, neutral or warm light.

Almost all produced today, light sources can be classified both on the principle of operation and the shape of the flask, the type of base, efficiency and the level of moisture and dust protection. However, it is more important that the nature of the light provides certain light bulbs. Very important accuracy of any light bulb is the index of its color reproduction, which is extremely desirable to ask the seller during the selection process. It is from this important indicator that it depends on how pleasant, juicy, rich and adequately, various colors present in the interior with artificial lighting will look. This color rendering index is indicated in the labeling of RA letters. Ideally, its value should be in the range from 90 to 100, but to create less normal lighting may be enough and 80-90. Out of any dependence on this from the index, when buying a lamp lamp must be remembered that the light may be warm or cold in reality, and this directly affects the choice and features of the use of appropriate lamps.
