1. INTRODUCTION

WHEN A LIGHTING PROFESSIONAL is going to work on a project, they need a lot of information to make the right decisions. All areas to be illuminated are purpose-built and designed for specific tasks. It may happen that depending on the time, certain areas could be used for other purposes, therefore depending on the activity to be carried out, we must illuminate the area adequately with a minimum lux which allows optimization of the work or task to be carried out


2. WHAT IS LUX

Lux is the international standard unit of illuminance and luminous emittance. It measures the luminous flux per unit area, it is equal to one lumen per square meter. In photometry, this is used as a measure of the intensity, as perceived by the human eye, of light striking or passing through a surface.

We have created in a very simple way two ways to know the necessary lux for your lighting project.


3. SLIDER METHOD

The first one is with a slider where you can click on the desired lux and will appear those areas with the minimum lux you have chosen.


SLIDER METHOD

Explanation

We chose the lux we want and appear all areas needed with those minimum lux


4. CHOSEN BUTTON METHOD

The second one is just choose the main area button you want to illuminate and all their areas will appear with the necessary minimum lux


CHOSEN BUTTON METHOD

Explanation

We chose the MAIN AREA and appear all areas their minimum lux


Obtaining the lighting levels exactly adequate in the area that we are going to illuminate is a complex matter with contrasting needs for different areas.

We must find the perfect balance between design and functionality to guarantee the correct execution of the task to be performed.

6. MAIN PARAMETERS TO OBTAIN LUMENS

For the lighting of a space we must not only know the size, various factors influence such as the reflectance of the wall (LRV), of which we have commented in the previous blog, the tasks or activities that are going to be carried out,

Knowing how many fixtures you need to adequately illuminate a room or space can be tricky. In addition to the size of the space, several factors can also influence, such as the activities that are carried out, the reflectance of the wall, factor of loss of luminosity, coefficient of use, etc. all those are the inputs needed to obtain the lumens (in the next blog we will generate a calculator, to provide estimates to your lighting needs in your projects)

Main Parameters to obtain the necessary lumens

6.1 Dimension of the space

Estimate the total square meters of the space, by inputting the length and width of the space. If the space is non-rectangular, estimate the equivalent rectangular dimensions.

Width of room, length of room and height, in linear meters


6.2 Brightness needs

Brightness needs will depend the activity or work being performed in the space, as well as personal preference.


6.3 colour of the walls

The reflectance of your walls will also play a role in the total amount of lighting needed. Spaces with walls of lighter colors will require less light.


In the next blog we will cover an Illumination calculator to obtain necessary lumens in an area.

The Illumination calculator takes inputs such as lumens per lamp, coefficient of utilization, light loss factor, area per lamp and produces output Illumination in lux.
