The key steps in the design process are:
- Know the requirements
This involves the understanding of what the lighting installation is intended to achieve. This mainly includes the direction of light, the material of surface, daylight.
- Determine the method of lighting
Next, you need to determine how the light is to be delivered, eg will it be recessed, surface mounted, direct or indirect, or uplighting is used, and what type of luminaire brightness.
- Select the lighting equipment
Once the method of lighting has been selected, the most appropriate light source can be chosen based on some attributes, such as lumens, total input wattage, efficacy, color characteristics, physical size, lifetime.
- Calculate the lighting parameters
The lighting parameters can be calculated manually or by using proper lighting software. The advent of computer modeling enabled a more flexible approach to lighting design and significantly increased the information available to the designer. After calculation makes sure that a proper documentation is prepared with the following details such as the type of luminaire used, the location of the luminaires, the assumed lumen output of the lamp, the light loss factor and the aiming points.
This is a useful tool in the presentation of a design, as a tool for the designer to check that the design is consistent with his own visualization of the space and to model specific lighting solutions.
