What is the measurement of light, in what units?

Light is simply necessary for every person for excellent mood and mental health. Thanks to him, we have the opportunity to see objects, to distinguish between their shape and the structure of materials, because the artificial prolongation of the daylight can increase the efficiency and productivity of labor. When choosing lamps and lamps for yourself, do not forget that the light should be chosen correctly. In premises of different purposes, we allow a variable approach to the intensity of illumination. And in order to choose the right fixtures, it is necessary to know what the light is measured in.

Light sources : natural and artificial

All specialists in human health care unanimously declare that the best source for people is a natural light source. It promotes the production of a number of vitamins and trace elements in the body, and is most favorable for the eyes. Every object can be seen under natural light without distortion and glare.

But, unfortunately, the modern world dictates its conditions, and we can no longer do without artificial light sources in the dark, otherwise the life of cities will completely stop. In each apartment there are a lot of different lamps, quite often we do not even know what the light is measured in and what to look for in the store when buying a variety of sconces, floor lamps and lampshades.

What kind of light is it?

No less important than the choice of light intensity, is the category or type of lighting. As we have already said, the most pleasant and safe light is a natural light source. It has a warm shade and least harms the eyes. The closest thing to a similar tone was the old incandescent lamps with a reddish tinge of light. They did not irritate the eyes and copied the sunlight falling into the windows of the apartments.

Modern lamps have many variations on the working element and the type of light. Before buying a new lamp, be sure to check which type of light is indicated on the package. For example, warm light will be ideal for living quarters. A neutral is usually used in offices and large industrial premises. Cold light is often used in watchmaking workshops, where its bluish tint helps to distinguish small details. Also, cold shades of light are welcome in the subtropical countries, where they create a feeling of extra coolness and transparency of the air.

Based on the above, you can always choose the right type of bulb, which will create the necessary mood and level of comfort in a relaxing home atmosphere. Psychologists have proved that the type of light plays a serious role in shaping the working mood in enterprises. Naturally, this also affects the productivity of labor.

By what parameters is the intensity measured?

The average buyer does not even think about how much light is measured and how important this information is. After all, light, being a physical quantity, is measured by many quantitative and qualitative parameters. They must be taken into account when planning repairs in the apartment and counting the number of bulbs required for each room.

Light can be measured by the following characteristics:

• Intensity;
• Force;
• Brightness.

Just so, "by eye" you will not be able to determine all the necessary parameters, so you should take care of buying devices that will help you to keep your vision and positive psychological mood at any time of the day.

What is the brightness of light measured in?

Brightness is a very important characteristic of a light source. It is the brightness of the lighting that allows us to see all the objects around us clearly and contrastively. Due to the brightness, spatial perception and exposure of white and black shades accentuates. In addition, it is the brightness of the light source that determines the degree of comfort when reading printed text, and this, as is known, directly affects the health of the eyes.

If we are talking about brightness, then remembering the units in which light is measured is very easy. Most often, candela is used to measure the brightness of the light source. This unit indicates the burning brightness of one candle, it is from it that all measuring instruments are repelled. Sometimes specialists apply also other units of measurement - Lambert and Apostille.

What device can measure the brightness of lighting?

Modern stores of specialized equipment are always ready to provide customers with a large number of different instruments for measuring the brightness of light. The brightmers and colorimeters work best with this work. They are able to give you information not only on the degree of brightness in a particular room, but also to determine the color temperature of the room.

Instruments with advanced functionality are suitable for professional photographers engaged in studio photography. And for everyday needs, a conventional light meter, which does not have additional options, is suitable.

In what units is the strength of light measured?

The power of light is a physical quantity. According to the school course of physics, it can be characterized as the energy of light, which can be transferred from one point to another in a certain period of time. This energy can change direction depending on the given trajectory.

The energy of light in candela is measured. That is, having bought a home-made display of a light, you can always measure not only the brightness, but also the intensity of light.

The intensity of light: what is measured?

The intensity of light is often called illumination, and it is also important when choosing lamps and various types of lamps. Remember what the intensity of light is measured, maybe even a child, although here it is worth taking into account some nuances.

If we are talking about the light flux incident on a certain surface, then it is necessary to measure it in lumens. But if you want to find out the degree of illumination of objects or surfaces, you need to talk about suites.

Such subtleties often frighten buyers who have somewhere heard that light is measured in lumens, and are perplexed about the incomprehensible units of measurement indicated on the package from the bulb. To cope with the problem of clarifying the degree of illumination in the room will help a very common device - a luximeter.

Luxmeter is a device that keeps healthy eyesight

If you can hardly remember in what units the light is measured, the luxometer will save your time and nerve cells. This device has a small size and weight, most often it consists of a display and a measuring part.

You can use this assistant at home, in educational institutions or in office premises. To get the data you just need to turn on the light source, and make measurements. After a few seconds, you will see the result on the display, which will show how safe your eyes are for light bulbs and lamps.

Illumination standards for apartments and other living quarters

In order to choose a comfortable lighting for the eyes, it is not enough to know what the light is measured in. We still need to know about the standards of illumination, which should be oriented, planning the location of lighting in the apartment.

Each room and room have their own necessary degree of illumination, which is measured in the suites. For example, children should be the most lit room in the apartment. There can not be less than two hundred suites, otherwise the baby's health will be under great threat.

The kitchen and the rest of the rooms can be illuminated for one hundred and fifty suites, but the utility rooms and corridors are quite manageable by fifty lux. Observance of these norms guarantees your family a comfortable existence, excellent mood and vision, which even the eagle will envy.

If you care about your family, you should know exactly what kind of lamps are installed in the lamps of your apartment. After all, every sane person dreams of returning from work to the house, where he is waited by gay children and a caring wife in good spirits. And an important role in making the dream finally become a reality, competently chosen lighting plays.
