In selecting new light sources, designers are guided by a number of considerations. Therefore, in this article, we focus on what to keep in mind when designing lighting.. The provisions found in the standards are the main, but not the only, determinant of trouble-free and functional use of a lighting system. A comprehensive approach guarantees the best results.
This article briefly discusses:
- design in accordance with valid recommendations,
- selection of lighting according to operating conditions,
- LED lamp control,
- the importance of buying luminaires from a reliable manufacturer,
- profitability of a project.
Designing lighting according to valid recommendations
Consideration of the standards and guidelines from other industry sources are the most important aspects of what to follow when designing lighting. In the case of workplaces, it is the Ministry Ordinance on general health and safety regulations (Journal of Laws 2003.169.1650) that is the overriding piece of legislation that obliges the employer to provide light of an appropriate quantity and quality. On the other hand, the PN-EN 12 464-1 standard is the basis for designers to develop a concept for a new system. It defines the parameters of light with respect to its qualitative and quantitative characteristics, for instance:
- illuminance,
- luminance distribution,
- colour aspects of light sources.
The standard provides recommendations and good lighting practice for most indoor workspaces. However, it is important to note that the document does not specify the requirements for the entire interior, but makes a distinction between the local and main lighting.
For street lighting, the design must be based on EN 13201. Outdoor lighting, on the other hand, should take into account a number of standards including EN 12 464-2.
General lighting and spotlighting matched to the operating conditions
The correct choice of luminaires for their places of use is worth attention when designing lighting. This ensures that the luminaires will last a long time. To this end, a lighting audit should be performed even before the concept is created. This will point out, among other things, where higher light levels are required. In production halls, for example, this could be welding areas, while in warehouses it could be packaging areas, where a minimum of 300 lx is recommended. Often, such working areas need to be combined with local lighting, which will complement the general system. However, in order to reduce the visual fatigue of workers, general luminaires should generate diffuse light.
A site visit may also reveal areas where specific chemicals are used in production processes. In this case, LED lamps should be made from material that is resistant to the conditions it may come into contact with. In particular, this applies to the housing, its tightness and the corrosion resistance of the LEDs.
Lighting control system for increased functionality
Smart lighting is worth considering during the planning phase. It is important for user comfort, additional functionality as well as savings. Such a system can be equipped with sensors or connected to a BMS. For example, with motion sensors, the output of light sources can be automatically adjusted when activity is detected. Another solution is to use incoming light sensors. A system equipped with these is designed to keep the average illuminance on the work surface constant, but it will adjust the power of the luminaires based on the amount of sunlight entering the room.
LED lighting from a proven manufacturer
Selecting a trusted partner is also an important aspect at the design stage. A manufacturer offering different types of lighting products, such as pendant lights or recessed luminaires and control systems, will be able to offer attractive solutions. In addition, a reputable lighting company will be able to help select a system that has proven itself in facilities with similar working conditions.
The cost-saving aspect, i.e. a short return on investment
A new lighting concept should also take into account the cost of installation in relation to the savings it will generate. This is often the most important element during the project, which is determined by the ROI expressed in years, an indicator that refers to the time to return on investment.
