The lighting in the workplace plays a central role in employee wellbeing and productivity. Above all it contributes to a safe and ergonomic working environment. So expert knowledge is essential for planning lighting in workshops, production halls, sales rooms and offices. This is because commercial lighting is subject to clear specifications that rarely apply at home.
What is good commercial lighting?
The European DIN EN 12464-1 standard regulates lighting in commercial premises from production halls to offices and salesrooms. The requirements are based on factors like the workplace function, safety and the type and duration of the activity.
DIN EN 12464-1 criteria for good lighting includes a pleasant lighting environment, sufficient illuminance depending on the visual tasks or area of activity, light distribution and uniform illumination, minimum direct and reflected glare or haze reflections and no flickering or stroboscopic effects.
Pay close attention to the quality of the daylight, light colour and colour rendering. Ideally, your lighting will adapt to changing conditions.
The following variables are particularly relevant:
- Illuminance: Lux (lx)
- Limit values for the assessment of glare: UGRL
- Uniform light distribution: UO
- Colour rendering index: Ra
These standards and guidelines ensure the safety of employees, products and machinery.
DIN EN 12464-1 does not specify any fixed solutions. Lighting should differ depending on the location and influence of daylight. It lays down the requirements for quantity and quality of lighting in indoor workplaces. It also makes recommendations for the implementation of good lighting. These help for planners while giving them the freedom to try out new technologies.
Bright and uniform light in production facilities
Lighting in areas like production lines must provide optimum conditions for visual tasks in a safe environment.
Uniform illumination helps to prevent accidents. For example, inadequate lighting makes it difficult for the human eye to tell whether a fast-moving machine is in operation or not.
In addition, the right lighting ensures efficient and concentrated work. For example, DIN EN 12464-1 specifies lighting requirements for different work areas. For example, illuminance in storage rooms should be at least 100 lx, while rough work requires 200 – 300 lx. Average requirements are a minimum of 500 lx and very fine work a minimum of 1,000 lx.
In industry and trade, interior lighting is often exposed to heavy loads such as dust, heat or moisture. Despite these adverse circumstances, the faultless functioning of each individual light is essential. For this reason, you should pay attention to IP protection class when purchasing.
The right office lighting for efficient work
In the office, shadow-free illumination (UGR value) and fatigue-free light (colour temperature) are important. So lighting design in the office should emmulate daylight which has a proven effect on concentration and health.
Daylight should enter from the side and be directed to the ceiling and upper half of the room. This allows even distribution throughout the room and simulates outdoor lighting conditions. If artificial light is used, it should have a cool white tone. This signals to the body that it is daytime which promotes performance and concentration.
Take care to avoid glare and reflections on screens. Consider glare-free lamps or a lighting arrangement that redirects glare.
Products in the right light – lighting in salesrooms
Sales rooms and shops often need sophisticated lighting planning. Customers should feel comfortable and be inspired by an exciting presentation. This is why more dramatic lighting arrangements and accents are used here.
Natural colour rendering (CRI = colour rendering index, measured in Ra) is used so that goods are presented appropriately.
This is especially important with clothing, for example in changing rooms where lifelike reproduction is a decisive purchasing factor.
LED – The technology of the future
Energy-saving LEDs are often the first choice when equipping, replacing or retrofitting lighting. LED lamps are more energy-efficient than halogen or energy-saving lamps. So, electricity consumption can be reduced by up to 70%.
In addition, LED light sources need very little maintenance due to their long service life. With up to 150,000 hours, LED industrial luminaires offer a service life three times longer than conventional LED luminaires.
They also have wide range of applications and can produce numerous different colours to suit your needs. LED technology is already available at a very low price too. So, nothing stands in the way of saving work, money and time!
