Light is simply necessary for every person for an excellent mood and mental health. Thanks to him, we get the opportunity to see objects, to distinguish between their shape and structure of materials, because the artificial prolongation of daylight hours can increase the efficiency and productivity. Choosing for yourself fixtures and lamps, do not forget that the light must be selected correctly. In rooms for various purposes, a variable approach to lighting intensity is permissible. And in order to choose the right fixtures, you need to know what the light is measured in.
Lighting Sources: Natural and Artificial
All human health experts unanimously declare that the best for people is a natural light source. It contributes to the development of a number of vitamins and minerals in the body, and is also most favorable for the eyes. Each subject in natural light can be seen without distortion and glare.
But, unfortunately, the modern world dictates its own conditions, and we can no longer do without artificial light sources in the dark, otherwise the life of cities would completely stop. In each apartment there are a lot of different lamps, quite often we do not even imagine what the light is measured in and what you need to pay attention to in the store when buying a variety of sconces, floor lamps and lampshades.
What is the light like?
No less important than the selection of light intensity is the category or type of lighting. As we already said, the most pleasant and safe light is a natural source of lighting. It has a warm shade and is less harmful to the eyes. Closest to a similar tone were old incandescent lamps with a reddish tint of the light flux. 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 what type of light is indicated on the package. For example, warm light will be ideal for living quarters. And neutral is usually used in offices and huge production facilities. Cold light is often used in watchmaking workshops, where its bluish tint helps to distinguish small details. Cold shades of light in subtropical countries are also welcome, where they create a feeling of additional coolness and transparency of the air.
Based on the above, you can always choose the right type of light bulb, which will create the necessary mood and level of comfort for you 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, labor productivity also depends on this.
What parameters measure the light intensity?
The average buyer does not even think about how 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 an apartment and counting the number of bulbs needed for each room.
Light can be measured by the following characteristics:
- intensity
- power;
- brightness.
Just like that, “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 maintain your vision and a positive psychological attitude 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 lighting that allows us to see all the objects around us clearly and in contrast. Thanks to brightness, spatial perception and exposure of white and black shades are aggravated. In addition, it is the brightness of the light source that determines the degree of comfort when reading a printed text, and this, as you know, directly affects the health of the eyes.
If we are talking about brightness, then it is very easy to remember in which units light is measured. Most often, candela is used to measure the brightness of a light source. This unit indicates the burning brightness of one candle, it is from it that all measuring devices repel. Sometimes experts also use other units of measurement - lambert and apostille.
What instrument can measure the brightness of lighting?
Modern specialized equipment stores are always ready to provide customers with a large number of various instruments for measuring light brightness. Brighteners and colorimeters do the job best. They are able to give you information not only on the degree of brightness in a particular room, but also determine the color temperature of the room.
Advanced function devices are suitable for professional studio photographers. And for household needs, a conventional brightness meter, which does not have additional options, is suitable.
In what units is the light intensity measured?
Luminous intensity is a physical quantity. According to the school physics course, it can be characterized as the energy of light, which can be transferred from one point to another over a certain period of time. This energy can change direction depending on the given trajectory.
The energy of light in candelas is measured. That is, having bought a brightness meter for home use, you can always measure not only brightness, but also light intensity.
Light intensity: what is measured?
The light intensity is often called illumination, and it is also important when choosing fixtures and various types of lamps. Even a child can remember how light intensity is measured, although some nuances should be taken into account here.
If we are talking about the luminous flux incident on a certain surface, then it is necessary to measure 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 scare buyers who have heard somewhere that the light is measured in lumens and are perplexed by the incomprehensible units of measurement indicated on the package from the light bulb. To cope with the problem of determining the degree of illumination in the room will help a very common device - a luxometer.
Luxometer - a device that maintains healthy vision
If you can hardly remember in which units the light is measured, then 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 such an assistant at home, in educational institutions or office premises. To obtain data, you just need to turn on the light source, and take measurements. In just a few seconds, you will see the result on the display, which will show how safe your eyes are for your bulbs and lamps.
Lighting standards for apartments and other residential premises
In order to choose lighting that is comfortable for the eyes, it is not enough to know what the light is measured in. You also need to have information about the lighting standards, which you should be guided by when planning the location of lighting devices in the apartment.
Each room and room has its own necessary degree of illumination, which is measured in suites. For example, the nursery should be the most lighted room in the apartment. There can not be less than two hundred suites, otherwise the baby's health will be in great jeopardy.
The kitchen and other rooms can be illuminated for one hundred and fifty suites, but the utility rooms and corridors are quite costing fifty suites. Compliance with these standards guarantees your family a comfortable existence, excellent mood and vision, which even an eagle will envy.
If you care about your family, you should know exactly what bulbs are installed in the lamps of your apartment. After all, every sane person dreams of returning from work to the house, where cheerful children and a caring wife in a good mood are waiting for him. And an important role in making the dream finally become a reality is played by well-chosen lighting.
