Introduction to Lighting Design Concepts

“Lighting design is a process. Specifically, it is the process of integrating light into the fabric of architecture.”

Lighting is the means to express the desired character of a space.

A successful lighting scheme should be integrated into the design at an early stage. The inclusion of lighting design during the conceptual phases will enable the lighting to enhance a perception of space, reinforce the activity within a space or highlight prominent areas.

Light plays a key role in the design of a visual environment. Work and movement is only possible when we have light to see. Architecture, people and objects are only visible is there is light. Light is an important factor in how we perceive our environment, influencing the way we feel and our reaction to a space.

All About Lux, Lumens, and a Few Other Terms

Luminous intensity.

Luminous intensity is the measure of visible light in a particular direction per sold angle. The SI unit for luminous intensity is the candela cd).

Luminous Flux

Luminous flux is the measure of the visible light output of a light source (a lamp). The SI unit for luminous flus is the lumen (lm).

Lux and Illuminance

The lux is the SI unit of illuminance and luminous emittance. It measures luminous flux per unit area. One Lux is equal to one lumen per square metre. In most homes an illuminance level of 100lx to 500lx is required. There is guidance for lighting level requirements, table further on in this article.

When we talk about power in lighting, we are looking at the electrical power required by the lamps. The unit of power is the watt (W).

What to Think about When You Are Designing Your Lighting Scheme

Of course, lighting design is more than planning the correct lux level and lighting intensities. It is about the fulfilment of physiological visual requirements, and the emotional requirements of the user. There are three main types of environments that require quite different approaches to lighting design.

• Environments for work, and places that serve the public. These places have a priority of functionality, safety and good communication.
• Environments for exhibitions and sale. These places focus on the exhibit and the users experience of viewing the exhibit.
• Environments for residence or tourism. These places are more personal, looking to create an atmosphere of comfort, relaxation, and so on.

– function

How is the space going to be used and what are the functional requirements of the space? Think about glare, visual comfort and task illumination. When designing for many situations we can refer to the current regulations and standards for the specific lighting requirements for certain tasks.

We must establish what activity will take place in the environment, how often and at what time of the day, and how important these activities are. Are these activities limited to specific spaces?

– behavioural effects

Lighting can have significant effects on human health and behaviour, it is important to consider how your lighting design will impact the users.

– aesthetics

Our perception of a space can be significantly affected by lighting. An excellent architectural design can be rendered lifeless and uninspiring with poor lighting. Likewise, a dull or unpleasant space can be significantly improved with the use of clever lighting design.

Don’t forget to consider lighting during both the day and night, both outside and inside. When will the building be viewed outside, when will it be seen/used inside. What impression do we want to make – does the lighting need to be inviting? Atmospheric?

– budget

Lighting design can often spiral out of control in terms of costs. It is important to consider the budget and come up with creative solutions to achieve the desired effect whilst keeping costs within budget.

– light and shadow

To take a room from being bland and boring to provide interest and atmosphere it is important to create texture and depth. By designing levels of light you can create well lit areas with soft shadows which will draw the eye to the lit area. This can be used to highlight a rooms main features to become a focal point, be it art on the wall, an ornament, or the dining table.

Light can be used to give the impression that the room is larger. A single pendant light in the middle of the room illuminates the centre but darkens the walls drawing the attention away from the walls. In order to make the room appear larger the walls need to be illuminated with the brightest light, drawing the visitors attention to the surrounding walls, making the entire room visible. Light will also be reflected into the room, giving a good general light to the room.

– direct and indirect light

Direct light, shines directly from a lamp into a room. It is bright and more directional, allowing you to control the area that you want to be lit. Direct light can cause glare which in time can lead to headaches and exhaustion. Anti glare baffles or louvres can help with this.

Indirect light reflects off a surface of a fitting or feature, giving a diffused wash of light onto a surface. This type of lighting can create a relaxed atmosphere since there is no glare and the even lighting reduces the strain on the eye. However, just uses large amounts of indirect light washing across all the walls can create a very bland and boring space so it is important to experiment with a combination of light and shadow to offer interest.

– colour of light

Light can be seen in a variety of colours and has a huge impact on your lighting design. Generally speaking there are cold colours and warm colours. Cold colours tend to have more blue inside them, where warm colours have more yellow. The different colours can be used to create different environments but also used for different purposes. Daylight is a cold light, and cold lighting is used in offices to create a natural daylight effect – also to achieve a good lux level for the task at hand.

Warm lighting is often seen in residential settings. A cold colour looks good when it is used at high lighting levels, whereas the warmer colour lighting looks better at low levels of light. In residential settings, you would often see the colder lighting used in areas such as bathrooms and kitchens where brighter lighting is required, and warm colours in bedrooms and living rooms.

– task lighting 

Task lighting is light provided for specific tasks being done in a space. Some rooms will require different light in different areas. For example, a kitchen will require extra lighting to the worktop when food is being prepared, and a living room may require extra lighting in a seating area for reading.

It is sometimes best to consider your task lighting requirements before the overall lighting.

– ambient lighting

Ambient lighting can be provided in two main ways, with direct downlighting or uplighting, where pendant luminaries provide upward light that reflects from the ceiling.

– controlling the light

There have been great advancements in technology when it comes to lighting and there is now more choice than ever for controlling the light. Consider switching options, dimming, wireless control, remote control and so on. How and where will the lights be controlled and how will this effect the user experience?

The most important element of the lighting design is to ensure it is considered at an early stage of development. Incorporate the lighting into the architecture to produce a scheme that is well balanced. There are many factors to take into account when developing the lighting scheme, not only regulations and general standards but never forgetting the user, and the purpose of the space.

Well explained, im a student at the University of ZImbabwe and lighting Design is one of my course which im much interested in.

Hello Shelter, My name is Mark and I am pursuing a bachelor’s degree in interior and landscape design at Kyambogo University in Uganda.

This semester we are handling a course unit on lighting design. And as a part of my research, my inquiries about lighting revolve around developing a feasible approach to calculating the amount of light necessary per room. And also identifying what considerations to make in an event that clients insist on using a particular lamp based on their design.

I would love to expand the conversation further if you don’t mind, to share and learn from you. Thank you.

Lighting design In Architecture Natural illumination & Artificial lighting Environmental Systems in Architecture 2nd lecture .. Eng. Nagham Ali Hasan

Properties of light: • Intensity (brightness) • Frequency (wave length) • Polarization (Direction of wave fluctuation) Speed of light: 299792.458 m/s ≈ 3*106 m/s The speed of light depends on the medium in which it is travelling.

Controlling light • Principles of controlling light • Reflection: depends on the reflecting coefficient of this surface. “Reflectance”

Transmission • how the light falling on a body is totally or partially transmitted • depending on the transmission factor of the given body.

Absorption • how the light falling on a surface is totally or partially absorbed • depending on the absorption factor of the given material. • Refraction • the direction of its path is changed • Interference • Interference is described as the intensification or attenuation of light when waves are superimposed

Lighting Resources: Natural Illumination Artificial Lighting daylight for interior spaces “Light from the sun” Such as : lamps “electric light- gas- oil lamps”

Artificial Lighting

Gas-discharge lamps Florescent lamps Sodium Vapor lamps

Electronic measurement devices for light

Artificial Lighting Forms of lighting for internal areas Semi Direct light : 1- is preferred for all general illumination of work rooms, meeting room, rooms in public use and circulation zones An angle of illumination between 70-90 2- can provide uniform wall illumination.

Directional Effect Forms of lighting for internal areas Some directional effects of light make it easier to recognize the details of a task; others make recognition more difficult.

INDirect LIGHTING Effect FL are used in indirect/direct lighting, but they may also be combined with filament lamps. Height of room h~3m It can give an impression of a bright room free of glare even at high a law lighting level. Defused lighting Effect

Artificial Lighting Forms of lighting for internal areas

Visual field • المجال البصري Visual field ويحتوي علي مجال الرؤية (FIELD OF VISION) وهي المساحة المرئية عند تثبيت كل من العينين والرأس. مجال النظر(FIELD OF VIEW) وهي المساحة التي يمكن رؤيتها عند تحريك العينين مع الاحتفاظ بثبات الرأس. ويستعمل تعبير المجال البصري للتعبير عن مجال الرؤية الذي ينقسم إلي ثلاث مناطق: المجال المركزي: وينحصر في زاوية رؤية مقدارها 2درجة وذلك عند تركيز النظر علي شئ محدد. خلفية المجال المركزي: وتنحصر في زاوية رؤية مقدارها 40درجة وهي المنطقة الخلفية لنقطة التركيز. البيئة المحيطة بالمجال المركزي: وتصل إلي زوايا رؤية رأسية مقدارها 120درجة وزوايا رؤية أفقية مقدارها 180درجة وهي الصورة العامة أو البانوراما التي تراها العين دون تركيز.

Visual Field (1) Field of View (2)

Visual field (1), preferred visual field (2) and optimum field of vision (3) of a person standing (above) and sitting (centre, below) for vertical visual tasks. Preferred field of vision for horizontal visual tasks. Preferred direction of view 25°.

Glare : • Glare is the discomfort or impairment of vision experienced when parts of the visual field are excessively bright in relation to the general surroundings. • Glare depends on the Reflectance. • Glare (m.lembert)= Illumination Intensity * Reflectance

Control of Glare Glare is controlled by the following means: to limit the luminance of the lighting sources in the direction of the eye, e.g. replacing bright source with a number of weak sources, to screen the light sources from the view, e.g. introducing downstand screens or light-diffusing fittings to the luminaires, to reposition the work station, to use working surfaces, paper, office machines etc. that have matt surface, to raise the background luminance against which the luminance sources are seen, to construct external obstructions or low transmittance glass to limit daylight penetration, and to construct windows on adjacent or opposite walls to reduce contrast.

Somedefinitions… • The luminance (Luminous Intensity) (I)…Unit: Candela: measure of intensity of light source in a given direction • The Luminous Flux (Φ)…Unit: Lumen: is amount of light energy radiated per second from a source of light. • i.e: The Luminous Flux (Φ)= 4π*L • The Illuminance: (E) …Unit: Lux: measure of light incident on the surface =Luminous Flux / area of the sphere surface = L/ r2 = lumen/ m2 lying at distance” r” from a source of light

Somedefinitions… 􀂄 􀂄 Candela (cd): measure of intensity of light source in a given direction 􀂄 Lumen (lm): total amount of light emanating from a light source 􀂄 Footcandles (fc): indicates the density of light landing on a surface = lumens per sq.ft.

Quantities and units

Lighting design concepts ensure optimum visual performance, high productivity safety at operating costs

INVERSESQUARE LAW • The illuminance on a surface which is produced by a single light source, varies inversely as the square of the distance from the source. • This is known as the INVERSE SQUARE LAW and is shown by the expression: • If the distance is doubled between the light source and surface, the illuminance E will fall to one quarter of the previous value.

COSINELAW If a beam of light from a lamp hits a surface at an angle, the illuminated area increases but the illuminance on the surface is lower than when the light is pointed directly at the surface.. This is known as the COSINE LAW and is shown by the expression:

The COSINE LAW is illustrated in the Figure. A 500 cd incandescent lamp is fixed at a height of 2 metres directly above a long bench, and the value of illuminance at point P is to be determined.
