![]() The visual aspects of the light are those that are concerned with the aesthetics and the narrative of the space (e.g. The technical requirements include the amount of light needed to perform a task, the energy consumed by the lighting within the space and the relative distribution and direction of travel for the light so as not to cause unnecessary glare and discomfort. The purpose of architectural lighting design is to balance the characteristics of light within a space to optimize the technical, the visual and, most recently, the non-visual components of ergonomics with respect to illumination of buildings or spaces. Overview The predominantly daylit auditorium of the Viipuri Municipal Library in the 1930s The objective of architectural lighting design is to balance the art and the science of lighting to create mood, visual interest and enhance the experience of a space or place whilst still meeting the technical and safety requirements. The basic aim of lighting within the built environment is to enable occupants to see clearly and without discomfort. Lighting design is based in both science and the visual arts. It can include manipulation and design of both daylight and electric light or both, to serve human needs. Play of light inside Jatiyo Sangshad Bhaban Exterior lighting of the Lloyd's building in LondonĪrchitectural lighting design is a field of work or study that is concerned with the design of lighting systems within the built environment, both interior and exterior. If the lumens supplied by a particular emitter are the same, light that is less far back and/or more closely focused will appear brighter because lux is concentrated in a smaller area than light that has travelled a greater distance and has been distributed over a larger area.Field within architecture, interior design and electrical engineering Therefore, the amount of lux in an area or on a surface can vary depending on the distance the light travels and the angle at which it is scattered. The further the light has to travel, the more it is scattered. Essentially, if the light comes from the emitter, it will be distributed over an area. One lux corresponds to one lumen per square meter (lux = lumen/m2). The more lumens a luminaire delivers, the brighter it will usually be. Lumen: The total power of the visible light of a light source is measured in lumen. This can be considered as light intensity within a certain range. ![]() Lux: The amount of light falling on a surface is referred to as illuminance, which is measured in lux.

Today the light level is more common in the range 500 - 1000 lux - depending on activity. Earlier it was common with light levels in the range 100 - 300 lux for normal activities. The amount of light needed to properly illuminate a task or process can vary depending on the application.Īccording EN 12464 Light and lighting - Lighting of workplaces -Indoor work places, the minimum illuminance is 50 lx for walls and 30 lx for ceilings. Providing the right amount of light for a task can have a significant impact on efficiency, productivity and safety. We offer a number of high-quality, energy-efficient LED strips and modules that can be used to solve a diverse range of lighting applications. The lux to lumens calculator will help you choose the illumination solution that best meets the specific requirements of your application. ![]()
