1 Applications in Focus Lighting for Healthcare 2. Ad'Hoc Pictography An introduction to the application of light in Healthcare Good health and well-being are much valued components of all our lives. Light, both natural and arti cial, is an essential ingredient for safe and ef cient Healthcare facilities that really do promote patient well-being. Feelings of well being, being at ease with our surroundings and receiving good quality light, arti cial or natural, have all been shown to have a signi cant impact on our health and our ability to ght infection or recover from treatment.
2 By ensuring adequate levels of light for safe movement within buildings, high quality light to aid diagnosis, treatment and recovery, and comfortable light for wards and day-rooms we can help minimise stress, reduce errors and improve conditions for both staff and patients. And by designing luminaires that are easy to maintain and clean we can help reduce energy consumption and control infection. This brochure shows how light and Lighting can support good health and well-being. Throughout, application speci c comments provide understanding of suitable techniques and equipment.
3 Performance, Ef ciency, Comfort (PEC). Three core values applied to Lighting in Healthcare This dynamic programme is based on the principle that Performance, Ef ciency and Comfort determine the visual effectiveness of Lighting . It has the ability to measure the impact on the people using it and the places in uenced by it. Thorn and Healthcare a partnership based on shared values. Performance: To provide an optimal Lighting solution. In hospitals, clinics and care homes, this can lead to less fatigue, quicker reactions and task completion with fewer mistakes resulting in higher standards of care.
4 Ef ciency: Ef ciency is concerned with the energy consumption, economics and practical aspects of a Lighting installation. Thorn Lighting products are carefully engineered and manufactured to produce practical, easy to maintain solutions that consume the least possible power and provide long-life, trouble-free solutions. Comfort: The ability to give people satisfaction and stimulation. Lighting in uences concentration and mood. Comfort is concerned with atmosphere, reassurance, and in the Healthcare environment, the well-being of the patient. 3. Green matters For every kWh of energy kg of CO2 is emitted and added to the greenhouse' gases in the atmosphere, increasing global warming Sustainability Arti cial Lighting represents 19% of the electrical energy consumed worldwide.
5 GREEN MATTERS. We have all witnessed cities alive with light from the air at night. We are all guilty of leaving lights burning unnecessarily at home or at work. We enjoy extravagantly lit shops and stores and mile after mile of perfectly lit, sometimes empty motorway stretching into the distance. This is unsustainable! Thorn have made a commitment to sustainability, to optimise the use of energy with technically innovative and intelligently controlled luminaires. The long term aim of sustainability is to conserve our eco-system and the human habitat for the next generations.
6 However, there must be a balance between energy saving and human need, with particular regard to our health, well-being and safety. The challenges of globalisation and its resulting social issues must be addressed in an effort to create international equal opportunities, and a more equitable share of the earth's nite resources. Thorn has a vision to be among the world's leading brands in demonstrating progress toward sustainability. We aim to do this by reducing our environmental footprint through innovative product design and manufacturing, minimising resource and energy use.
7 We will continue to apply these products and ideas in well conceived intelligent Lighting solutions. Daylight and Lighting controls Daylight, an in nite resource can be used in partnership with arti cial Lighting controls to conserve energy and hence add to an installations sustainability. Using daylight The use of natural light in any building connects us to the outside, to the weather conditions, a view to the world beyond and helps create a sense of the passing of time. This is particularly relevant to patients in hospital and residents in a care home.
8 A connection to the outside, from a relatively unchanging environment inside, helps relieve the feelings of isolation and is a boost to morale and an aid to recovery. Our developing knowledge on the impact of light on circadian rhythms and health disorders such as seasonal affective disorder (SAD) provides important input when architects and planners are designing buildings. Daylight, whether from windows or atria, produces a variety of bene ts and Lighting effects, different to those provided by arti cial Lighting . Additionally the correct use of natural light has the added bene t of helping to reduce energy consumption and associated costs.
9 Richard Seymor 4. Lighting controls Lighting controls can add much to the operational ef ciency of an installation. Typical energy savings of 30-70% are possible with simple paybacks that make good economic sense. Controls provide one or both of the following two simple functions: Switch (on or off) or dim (raise or lower output). The essence of Lighting control systems: Absence and presence detection, using sensors which respond to the movement of people entering and leaving a space can reduce demand by turning the Lighting on or off. This can be overridden by manual switches or a handheld controller to give users a sense of control over their environment.
10 Daylight switching uses a dedicated photocell switching the Lighting on or off in response to changes in the ambient light level. When suf cient daylight is present the Lighting is automatically turned off. Daylight dimming operates in a similar way to daylight switching, automatically increasing or decreasing the arti cial Lighting in response to changes in the ambient light level, including the on/off option. Controls save energy by providing electric light only where and when needed, these deliver the best results where they have been carefully planned and effectively implemented.
