  • Entrance Areas

    Attractive lighting in the entrance area can make a hospital seem more welcoming. A harmonious lighting atmosphere makes people less apprehensive, inspires confidence and makes the surroundings look inviting. Also, a patient or visitor is less likely to feel intimidated if they can find their way around easily.

    Entrance halls generally consist of four distinct zones – the entrance area, the reception desk, the waiting area and the area that leads people into the rest of the building. The entrance hall almost always connects to a restaurant and a gift shop. Attraction and guidance are the main priorities here. The reception desk in particular is a multi-purpose area in which many different tasks are performed, including reading, writing, computer work and, most importantly, communication. The reception desk also needs to be the eye-catcher in the space, so that visitors will be drawn to it straight away.

    Corridors and Circulation Areas (Public Areas)

    Corridors and other circulation areas form the link between the different areas of the hospital, which is often open 24 hours a day. Because people prefer to enter a brightly illuminated corridor than a dark one, specific lighting requirements are specified to create optimum guidance, particularly for visitors who have come to the hospital for the first time. In addition, the comfort of patients who are being wheeled along the corridor on trolleys also has to be taken into consideration. They are looking upward, and a high level of brightness can be extremely uncomfortable. In public corridors where patients are not being wheeled along, the lighting should focus more on guidance and ambience.

    The lighting in corridors and other circulation areas should be coordinated with the lighting in the adjacent rooms to avoid differences in illuminance when a person passes from one area to another. This often means that provision must be made to reduce the illuminance in the corridor at night. In cases where the corridor does not receive sufficient natural daylight during the day, the artificial light in the corridors should facilitate visual adaptation by providing a fairly high illuminance on the wall opposite the doors of the rooms.

    Waiting Rooms

    There’s no better place to star t with ambient lighting than the waiting room. It sets the tone for the entire hospital. In the waiting area of an outpatient department, where people may be tense, anxious or in pain, a soft homely atmosphere has a welcoming, calming effect, while the impression of hygiene and cleanness fosters a sense of trust.

    In many cases, the waiting room could offer patients and visitors a much more pleasant experience than it currently does. As well as the standard basic facilities – chairs, books and magazines – there could, for instance, be a visitor’s desk where you can borrow radio headphones, portable audio players, audio books and hand-held video games. There could also be an area with individual TVs and headphones to entertain you without disturbing others, and tables where you can play cards or even plug in a laptop.

    Lighting solutions for a waiting room should be designed around the people – children or adults – who are going to experience them. A home-like lighting ambience has a settling effect on patients as they wait. General lighting combined with dimmable wall lighting and flexible free-standing or table luminaires will radiate a relaxing, ‘domestic’ ambience. Such a positive ambience can be achieved by using more indirect than direct lighting, in warm white light, with different lighting systems for different parts of the waiting area and not-too-dramatic accent lighting. Color accents from LED elements can be used to create distraction and promote social interaction, while daylight-following dynamic lighting will foster a stronger sense of well-being and connection to the outside world.

    Examination, Imaging and Radiology Rooms

    Going to the hospital is not something people usually look forward to - it’s a time when they feel concerned and vulnerable. Colored lighting during examination and diagnosis can help people to feel more at ease and create distraction. Patients or staff can select a ‘color’ for the room, then see the transformation of the environment in front of them, making them partners in the procedure. Functional lighting above but outside the main axis of the scan table can be switched on to prevent glare for the patient and to facilitate preparatory activities. All settings can be managed from the control room.

    Design can be used to create an even more reassuring environment, improving the way patients feel during a variety of processes, including scanning procedures. Pozeen has focused on four key experiences that can be impacted by the clinical environment.

    Patients may feel anxious and intimidated, unsure of what will happen next as they wrestle with concerns about their medical condition. They may not have visual contact with clinical staff during some procedures; at the same time, they are separated from their loved ones, resulting in feelings of isolation. Also, an individual may feel like ‘just a number’ with no control over what’s happening. Lastly, hospital procedures can be time-consuming, and staffing shortages can contribute to long waiting times, resulting in stress for staff and patients alike.

    Ambient experience is a Pozeen healthcare solution to create people-centric environments in healthcare facilities. It is based on research into the values and needs of patients and medical staff, and integrates architectural elements, interior design and technologies such as lighting, video projection and sound. The result is a holistic, multi-sensorial experience that helps patients to remain calm during the procedure, staff to perform more efficiently, and institutions to differentiate themselves with a healthcare environment that truly puts people first.

    Operating Theaters and Intensive Care

    Surgical operations present some of the toughest challenges for physicians and medical personnel, particularly in terms of visual performance.

    Key requirements in an intensive care unit include rest for patients who are severely ill, constant patient monitoring and fast response times in the case of an emergency.

    To avoid adaptation problems for the human eye when switching lines of sight between the operating field, where high lighting levels up to 100,000 lux are possible, and the surrounding area, the illuminance of the room lighting needs to be graduated – increasing up to 2,000 lux in the immediate vicinity of the operating table. This lighting needs to be provided in addition to the general room lighting, which is rated at an illuminance of 1000 lux. Cleanroom luminaires with IP65 protection are used to provide background and general lighting. These luminaires meet the hygiene requirements of rooms where surgical operations are performed.

    Unlike in ordinary wards, the lighting systems used in intensive care units are generally separate from the more complex installations for medical equipment. Comfort lighting is an exception. Supplementary observation lighting enables patients and medical equipment to be monitored at night. In rooms where patients are monitored through observation windows, the level of lighting needs to be significantly lower than it is in the room from which the patient is being monitored. Dimmable lighting is advisable here to prevent any reflection on the glass.

    Patient Rooms

    Nowhere is the impact of the advances in hospital care felt more than in the patient room. As room decor becomes more cozy and home-like, dazzling new technology is bringing the future directly to the bedside, giving clinicians the power to monitor patients more carefully and giving patients more control over their own environment. The challenge for hospital designers is to create flexible, welcoming rooms that can accommodate ever-changing technology, encourage loved ones to spend more time with patients, and allow staff to work more efficiently.

    Lighting for the specific patient areas needs to have a number of qualities. In addition to functional lighting for a variety of medical treatments at the bedside, there needs to be a lighting system that creates a homely feel, such as a bedside lamp that can be set according to personal preferences when the patient is reading or socializing with visitors.

    Overhead general lighting offers dynamic daylight qualities. In situations where no daylight is available, daylight-sensing qualities should be incorporated into the general lighting system. Other general lighting can be concentrated above the traffic areas. The light should be soft, self-explanatory and easy to control. Dimming or presets for day, night and emergency lighting can be used. The latest developments offer dynamic daylight qualities overhead.

    Office Spaces

    Good office lighting design addresses different aspects of light. For example, light in offices must be bright enough to facilitate the performance of visual tasks, but if the brightness is too high, it can cause glare. The color rendering of the light is also important. Then there is the emotional component of light: it affects how we feel.

    Accordingly, artificial lighting can play a significant role in improving the healthcare experience by creating a relaxed or uplifting ambience. Light can improve our sense of emotional well-being.

    Over the past two decades it has become clear that light also has a biological effect. A typical example is a heightened alertness brought about by higher color temperatures or higher lighting levels. The resulting reduction in sleepiness helps medical practitioners, for example, to combat the ‘morning blues’ or the ‘after-lunch dip’. Lighting can also be used to suppress melatonin at night and cause a phase shift of the circadian rhythm. This is particularly relevant for doctors and nurses working night shifts.

    Daylight, the form of light with which we are most comfortable, is never constant. It changes in intensity over the course of the day and the seasons, affecting our emotions, moods, perception and performance. Most of these changes are gradual, with slow transitions that we only perceive at a subconscious level. This suits our biological rhythms and the patterns of our daily lives. By bringing the dynamics of daylight indoors we can create ‘natural’ lighting that stimulates and inspires those living or working there.

    Pozeen lighting controls enable us to create ‘personal light’ and ‘dynamic ambience’. ‘Personal light’ allows individuals to control the lighting to suit their personal preference. ‘Dynamic ambience’ controls the ambient lighting in an entire room, animating the space by varying the character of the light over time, for example by changing the lighting level and color temperature according to a programmed scenario.

    Architectural and Outdoor Areas

    Our lighting systems for parking areas ensure that all vehicles and pedestrians can move around safely, whilst also promoting general orientation and visibility of obstacles. At the same time, light nuisance for the surrounding area is kept to a minimum.

    The level of illuminance required depends on the volume of traffic: 20 lux where the average number of vehicles is high, 5 lux where it is low. In general, standard street lighting luminaires are used to illuminate car parks. A mounting height of 6 to 8 meters is appropriate for such luminaires, depending on the size of the car park. In the case of larger areas, floodlights might be used at a higher mounting height.

    The walk from the car park to the hospital entrance often takes visitors along a path or walkway across a piece of open ground, e.g. a small park or garden. Here, marker lights, for example, can provide guidance, while subtle illumination of trees and other features can help create a pleasant and inviting ambience.
