How to calculate the lighting of the room in the program online, and choose LED lights
The calculation of lighting is important for comfortable conditions at work or at home. Quality lighting is not just about convenience, but also human health. And at excess or lack of light not only sight suffers. This factor can also cause high fatigue and psychological discomfort. Therefore, it is very important to choose the right lighting.
How to choose the right lamp?
Illumination is the amount of luminous flux required for illumination 1 sq. m of space. It is measured in Suites. There are lighting standards for living and working spaces. Using them and various auxiliary tables, it is quite simple to calculate the required amount of light for a room.
There are special online programs for calculation. The interface of such programs is quite simple and clear. The following parameters are set in the corresponding fields:
-
Dimensions of the room;
- Dimensions of the illuminated surface. Its height can be found in the lighting standards. Usually for the floor it is 0, and the height of the desktop 0,8 m;
- Approximate coefficient of reflection of light from the surface. It is not scary if their exact digital values are unknown. You can focus on the specified background brightness;
- The type of lamp and the number of lamps in it is selected. Usually when choosing a lamp you can find out and the lamps are available for him;
- The room category is selected from the list, and the program automatically issues a light rate.
Luminous flux and lamp stock ratio are important. It takes into account the aging of lighting fixtures and their pollination. It is chosen based on lighting standards. For incandescent lamps in our country it is 1.2, and for bit - 1.4.
There are exceptions for the premises, where especially vigilant. In such cases, the higher stock ratio is taken. The result can usually be printed out on a printer.
There are calculators for calculating incandescent lamps and halogen or cells. They will help to calculate, how many light sources are needed in a room.
A little about lamps
Natural light is optimal for humans. To bring artificial lighting closer to natural, you need to carefully choose light sources and their power. Many factors are taken into account here, including indoor conditions.
There are several types of artificial lighting:
-
General is used to illuminate a room or office as a whole;
- A functional option is required, to provide light on the work surface, example, on the kitchen or desk, on the machine. They can divide the room into zones;
- Accented light is used for illumination, creating a certain atmosphere in the room, for visual effects. LED constructions are usually used here;
- Combined lighting is usually used for special requirements. When the accuracy of work is required.
To calculate the illuminance correctly, it is better to use a special program on the Internet. With its help it is easy to choose the best option for a particular room or office.
see lamps
To calculate the illuminance you need to know the various parameters of the width and length of the room, the height of the suspension of lighting structures, stock ratio, luminous flux. But, first of all pick up lamps, to be used.
The main types of lighting elements:
-
Tungsten filament incandescent lamp. The simplest element of lighting, however, its spectrum is closest to the sun;
- Gas-charging lighting element here the light is produced by an electric discharge in vapors of metal or gas. This type includes: energy saving, mercury lamps, for street lighting. Sodium arc tubular DNAT, high pressure DNaZ;
- LED or led lamps are modern and comfortable. This is a new word in light technology;
- Halogen lamps among them are quartz, CG incandescence, metal halide, mirrors;
- Fluorescent white and daylight, compact;
- Spherical xenon DKSSh.
Naturally, each type has its own characteristics. Therefore, before choosing one or another option, you must consider the conditions, in which they will be used, type of premises and other factors. Such, as a stream of light, element power and color reproduction.
According to the program, it is easy to calculate the lighting of a particular room based on the rules. The type of lamp and power is chosen. There is such a criterion, as color transfer. This concept includes color temperature and shade of light. The first varies from red to blue. Less than its value is close to red, and more to blue.
Shade, usually, many lamps are cold or warm. It is he who sets the tone of the light flux. With standard incandescent elements with color rendering, everything is simple. It has the same meaning, and shade of light. In a fluorescent lamp in a compact design, you can choose a warm or cool shade and color.
There is another point. When choosing a lamp, primarily, need to look, how many watts the cartridge is designed for. Manufacturers usually indicate it on the cartridge or the lamp itself. This is especially important if halogen or incandescent lamps are used. After all, they produce heat. And when installing a more powerful lamp, than indicated, the cartridge may melt.
A little about the lamps
There are also a few things to keep in mind when it comes to lighting. What you should pay attention to in the first place?
-
At the place where the device will be installed. It can be a wall or a ceiling;
- How high is the light source;
- Transparency of plafonds;
- Direction of light.
You must take into account the color of furniture and wallpaper. After all, dark tones absorb light, the lights on the contrary reflect. Therefore, if the design of the room is sustained in light shades, accordingly, losses in illumination can be avoided. When the interior is darker, then the light should be more.
The matte shade for the lamp gently distributes light, but at the same time some loss of illumination in comparison with transparent is possible. If you choose a lighting element more powerful, example, incandescent lamp 100 W she compensates for these light losses.
As for the location of the light source, then the lamp is installed ??above the floor gives more light. Example, a chandelier on the ceiling illuminates a large area, than the sconce is fixed to the wall.
convenience of calculations
What are the advantages of self-calculation of lighting using the program?
-
Energy savings due to the optimal choice of lamps and light sources
- There is no need to invite a specialist home for the calculation.
- It also helps to determine the exact number of structures for lighting
Using an online calculator is quite simple. The result will be accurate.
Choose the number of lamps
It will help you choose the right number of lighting fixtures for the room. You will need the parameters of the room and the reflection coefficient of the ceiling and floor. The distance between the work surface and the lamp. Type of lamps and their power. The utilization factor of the lamp is its type and power. You also need to enter lighting standards for the room.
So you can make an accurate calculation of all the necessary lamps. And provide comfortable conditions at work or at home. Example, office ceiling height 3,0 m, it has light walls and suspended ceilings. Hence the flow utilization factor 0,5. According to the standard lighting should be 400 suites.
Accordingly, the luminous flux will be 24 000 lm. So, determined, what you need when using an incandescent lamp 1,2 kW for a small room. But experts in light technology usually recommend the use of modern LED systems. Then energy consumption will be 200 W. From here it is easy to calculate the number of required lamps.
It is necessary to pay attention to the type of local or primary light. That is the upper light, illuminating the whole space or local, which includes floor lamps, sconce, table lamps.
If it is a living room, then the main source of light is most reasonable to make chandeliers lamps with a matte shade. This distributes the light evenly and softly throughout the room. If you want to illuminate part of the room, then a good option would be a lamp, on which a layer of reflective material is applied. This will create a more local lighting character.
other functions
The program allows you to enter the parameters of existing premises and devices used, determine how well the lighting meets the standards and, if necessary, adjust it. To do this, are introduced:
-
Number of lamps;
- The number of lamps in each piece;
- The power of one lamp in the device in watts;
- Room area.
Usually the optimal power of one lamp for a standard office space 20 W / sq. m. You can also calculate the area, which can be illuminated by the device. Or the maximum height for him. Usually, the programs have hints.
LED lighting
Such lighting fixtures can make living and office spaces comfortable and more modern. exept this, lamps, allow you to save by providing sufficient light flux. The question arises, what exactly are the lamps and how many LED lamps are needed for a comfortable environment.
In special programs, you can calculate the required number of LED lamps by entering data and auxiliary materials. Power is introduced, number and location of lamps. The coefficient of its pulsation is also important here, and other lighting indicators.
In the data sheet of each led lamp there is data on the amount of luminous flux. Therefore it is necessary to take simply SNiP norm which is easy to find on the Internet and to multiply on footage of the room in square meters. The value obtained is divided by the luminous flux of one led lamp. Based on this, the required number and power of LED lighting fixtures is determined. This optimizes energy consumption.
It is worth considering, that the more sources, the smoother the light. So if there is a design option for lighting and several lamps, which will be built into the ceiling. It is recommended to distribute at equal distances from each other 8 light bulbs power 5 W.
Or you can concentrate them in the desired area of the room. You can make several switches and illuminate if necessary one or another part of the room. Or turn everything on at once to get a bright light.
A few words at the end
By the way, the use of different types of light sources in one room is quite acceptable. Usually try to find the smallest number of devices, but so that the lighting was comfortable. It is important to adhere to its uniformity or zonation
Calculation programs are very simple step-by-step editors, which are easy to work with. Therefore, when you need an accurate result, they are the best option for calculating the illuminance. So, you can not only reduce energy costs, but also to achieve maximum comfort in the work and home environment.
