Information
The calculation of illumination is done to understand how many fixtures need to be installed, how many bulbs to buy, and how brightly to illuminate the room. Government authorities monitor compliance with standards and penalize businesses for violations. To avoid fines and ensure employees have productive working conditions, it is necessary to know how to calculate the level of illumination.
To make an accurate calculation of the illumination of a room with LED fixtures, you do not need to have specialized knowledge. It is enough to use a simple and user-friendly online calculator that will calculate the illumination with LED lamps for various types of premises. By knowing the dimensions of the room and other parameters, you can quickly and effortlessly obtain the final result.
Functions of the Online Calculator
The online calculator for LED fixtures is a simple software tool consisting of six data input fields and two result output fields.
The calculator will calculate the required illumination of the room and the necessary luminous flux of a single fixture. The final result can be saved as a PDF file or printed with one click of a button.
Working Principle of the Calculator
To obtain the final calculation, you need to enter the initial data in the calculator menu:
- Select the type of room.
- Determine the standard level of illumination, in lux, either automatically or manually.
- In fields 3-5, specify the dimensions of the room: length, width, height in meters.
- Specify the number of fixtures.
After entering this data, the calculation results will appear below:
- Required room illumination, in lumens.
- Required luminous flux of a single fixture, in lumens.
Reference
Illumination – the ratio of the luminous flux falling on a surface to the area of that surface. Measured in lux.
LED fixture – a lighting device whose main components are an LED (a semiconductor element) and a driver (a switching power supply that converts AC to DC).
Luminous flux – a physical quantity that characterizes the amount of light power in a particular radiation flux. Light power refers to the light energy transferred through a certain surface by radiation per unit time.
Methods of Calculating Illumination for LED Fixtures
Calculating the illumination of a room with LED fixtures is a key step in lighting planning. It is important to consider not only the room dimensions but also its functional purpose, the type of fixtures, and the illumination requirements. There are several calculation methods that help determine the optimal number and placement of fixtures to achieve the required level of illumination.
