LIGHTING IN HOSPITALS
Lighting or illumination is the deliberate use of light to achieve a practical or aesthetic
effect. Lighting includes the use of both artificial light sources like lamps and light fixtures,
as well as natural illumination by capturing daylight .

Ambient (general lighting)
Provides an area with overall illumination. Also known as general lighting, it radiates a comfortable level of brightness without glare
•Task lighting
Helps you perform specific tasks, such as reading, grooming, preparing and cooking food,
•Accent lighting
Adds drama to a room by creating visual interest. As part of an interior design scheme, it is used to draw the eye to houseplants, paintings, sculptures and other prized possessions

  • People used to laugh at me behind my back before I was in shape or successful. Once I lost a lot of weight, I was so excited that I opened my own gym, and began helping others. I began to get quite a large following of students, and finally, I didn't catch someone laughing at me behind my back any longer. CLICK HERE NOW ➤➤ http://t.cn/A6PnIGtz

  • Just recently I emailed my friend and said "Funny (well, not really) how many psychologists, doctors, dieticians, support groups, hospitals, and even a hypnotist, I went to over the years that couldn’t help me – and all it took in the end was a simple site like this, and a supportive partner! I guess everyone is different though... ◆◆◆ http://scamcb.com/bulimiarec/pdf

  • If only we knew about this 10 years ago! I wasted a ton of money on garbage 'stop snoring' products like mouth guards, throat sprays, lozenges and nasal strips, to name just a few! None of them worked. My doctor explained to me that the only way I was going to fix my snoring was with an operation, although he did say it was a last resort. I am so glad I didn't risk it because after finding your program my snoring has considerably decreased! If only I knew about this 10 years ago!  https://bit.ly/37PhtTN

  3. 3. Lighting or illumination is the deliberate use of light to achieve a practical or aesthetic effect. Lighting includes the use of both artificial light sources like lamps and light fixtures, as well as natural illumination by capturing daylight . Enhanced aesthetics incorporated into fixture design, as well as the ability for the luminaire to light architecture details, are certainly important. But patient-perceived quality of light and the effects on a healing environment are a critical factor, too. Lighting can and does contribute to improved patient outcomes as well as improved facility safety. What is lighting ContemporaryTechnology(M.arch-Health care architecture) 3
  4. 4. Basic types of artificial lights There are three basic types of lighting that work together • Ambient (general lighting) Provides an area with overall illumination. Also known as general lighting, it radiates a comfortable level of brightness without glare • Task lighting Helps you perform specific tasks, such as reading, grooming, preparing and cooking food, • Accent lighting Adds drama to a room by creating visual interest. As part of an interior design scheme, it is used to draw the eye to houseplants, paintings, sculptures and other prized possessions ContemporaryTechnology(M.arch-Health care architecture) 4
  5. 5. Effects of Light on Patients Mood Bright light is effective in elevating mood in depressed patients Morbidity and mortality An association has also been found between staying in a sunny room and a decreased need for analgesic medication following surgery, Patients who were accommodated on the brighter side of the hospital (with 46% higher-intensity sunlight on average) perceived less stress and took 22% less analgesic medication than those on the duller side. Lighting intensity has an effect on the behavior of patients with Alzheimer’s Disease. When a constant level of light intensity was maintained using design adjustments, such as micro slatted glazed windows and electronic lighting controls, a significant drop in agitated and disruptive behavior's was demonstrated.

  8. 8. Performance, Efficiency, Comfort (PEC) Three core values applied to lighting in healthcare 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. Efficiency: Efficiency 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 influences concentration and mood. Comfort is concerned with atmosphere, reassurance, and in the healthcare environment, the well-being of the patient.

  9. 9. ILLUMINANCE (ILLUMINATION LEVEL): Illuminance is the measure of illumination defined as the ‘ratio of luminous flux incident on an infinitesimal element of the surface containing the point under consideration to the area of the element. IS Code 4347 Illumination level for hospitals varies from 100 lux in patient’s room to 1,00,000 lux in operation theatres. ContemporaryTechnology(M.arch-Health care architecture) 9

  11. 11. ENTRANCE First impressions count, so here’s the perfect opportunity to create a great first impression with a welcoming ambience. Attractive lighting in the entrance area can make a hospital more inviting. Luminaires used General lighting • Energy savings of up to 50% compared with conventional CFL down lights • Latest LED technology for consistent light output, stable color performance and good color rendering • Easy installation and a long lifetime Suspended above the counter • Graceful slim pendant with a shiny mirror coating to add a stylish accent • Adjustable in height and available in 1, 2, or 3 tubular shuttles • Energy-efficient LED technology helps save energy Accent lighting back wall • High-quality accent light due to dedicated LED reflector system • Good color consistency and high color rendering for extra sparkle • Low maintenance costs thanks to long lifetime, and low energy consumption Wall mounted • A family of wall, ceiling and suspension lamps of extremely reduced thickness • Latest LED technology allows the thickness to be reduced to the minimum making Strip particularly suitable for places requiring unobtrusive lighting • The opaline polycarbonate diffuser screens allow modular lighting units of different dimensions and brightness Entrance Hall Generally consist four zones 1.Entramce Area 2.Reception Desk. 3.Waiting Area. 4.Area leads to the people In to the rest of the building. Functionality and decorative ContemporaryTechnology(M.arch-Health care architecture) 11
  12. 12. WAITING ROOM General lighting • Cost-efficient and sustainable down light • Can be used to replace conventional CFL down lights • Features the latest LED technology • Extreme low power consumption • Stable color performance and high color rendering Wall mounted • An elliptical lamp in opaline polycarbonate that can be fixed to the wall at a normal or tilted angle, singly or in rows, to create a lively cluster of lights ContemporaryTechnology(M.arch-Health care architecture) 12 • At entrances and in waiting areas, light has an important role to play in creating a welcoming and friendly atmosphere. • Lobbies and transition spaces must put the patient and the visitor instantly at their ease. • Pay special attention to grading the illuminances and reflectance's of successive spaces, so that important spaces feel welcoming.
  13. 13. ContemporaryTechnology(M.arch-Health care architecture) 13 DESIGN CONSIDERATIONS • Layering of light can create a pleasant and relaxing environment. • Task lighting and decorative lighting can help provide a welcome entry. • Using a combination of overhead, recessed and indirect lighting can enliven these areas.(1) • Energy efficient sources and glare-free appearance are important factors to consider. • Recommended illuminance for these areas is 10 - 30 FC (horizontal) and 3 - 5 FC (vertical). DIFFERENT OPTIONS FOR LIGHTING These small but critical areas in a healthcare setting can set the tone for the entire patient or visitor experience. The wayfinding journey usually begins and ends from here. Greeting, reception and direction as well as visitor accountability are all orchestrated here.
  14. 14. CORRIDORS 1. For a hospital, which is often open 24 hours a day, corridors and circulation areas are the arteries of the building. They link the different areas together logistically. 2. Patients and visitors who are on their way to a doctor or specific department will naturally benefit from a brightly illuminated corridor rather than a dark one and specific lighting can be used to optimize guidance. 3. In areas where patients and visitors circulate, factors of key importance are guidance, safety and re-assurance, which can be supported by 4. using diffused homogeneous lighting and avoiding dark spots. For corridors where patients are wheeled along on trolleys, it must be taken into consideration that sharp contrasts can be extremely uncomfortable when they are looking upwards. General lighting • State-of-the-art LED lighting • High luminaire efficiency • Choice of optics • Designed to fit in a wide Range of ceiling types (hospitality areas) Sensor • Advanced occupancy control and daylight regulation with separate window and corridor algorithms Accent lighting wall • High-quality accent light due to dedicated LED reflector system • Good color consistency and high color rendering; extra sparkle • Low maintenance costs thanks to long lifetime, and low energy consumption Alcove • Excellent output of white or solid color light • Multiple options for design flexibility • LED system means energy-efficiency, easy installation, and a long lifetime ContemporaryTechnology(M.arch-Health care architecture) 14

  16. 16. ContemporaryTechnology(M.arch-Health care architecture) 16 DESIGN CONSIDERATIONS • Color selection of finish material used in corridor ceilings, walls and floors in relation to incident reflectance is critical in these areas. • Minimize extremes of brightness within these spaces. Excessive brightness contrast can disorient residents. • Elimination of glare is one of the most important design criteria for corridors. Recessed indirect or cove lighting are recommended. Properly shielded down lights can also work effectively in these areas. DIFFERENT OPTIONS FOR LIGHTING
  17. 17. EXAMINATION ROOMS Examination light • Illuminance, Low Level: 25,000 lux (2323 fc) at 18″ (46 cm) • Illuminance, High Level: 50,000 lux (4645 fc) at 18″ (46 cm) • 4600 K color temperature Examination light / dynamic panel • Recessed unit consisting of general lighting needed for examination and treatment in combination with a mood panel to show dynamic content ContemporaryTechnology(M.arch-Health care architecture) 17 Patient evaluation and medical procedures begin in the examination room. Visibility, visual comfort and visual appeal must all be addressed in the lighting design process.
  18. 18. ContemporaryTechnology(M.arch-Health care architecture) 18 DESIGN CONSIDERATIONS • Indirect lighting and the ability to switch the level of lighting intensity is critical. • Consider a combination of recessed indirect/direct luminaires and specific task lighting. • Proper placement of luminaires is critical to avoid veiling reflections in windows and computer monitors. • Additional lighting should be installed directly above work surfaces, along with undercabinet lights for counters and downlights over sinks. • Skin and tissue tones are best rendered under light sources with a high color rendering index (CRI) of 80 or above. DIFFERENT OPTIONS FOR LIGHTING
  19. 19. PATIENT ROOM • Soft and comfortable lighting, with full luminous surface 2 1 34 Glare-free light for visual comfort 1. Dynamic white light: ceiling modules that provide daylight rhythm with varying light levels and warmer or cooler light, as well as simple examination light for staff. 2 Ambient light: LED based colored light line in cove opposite the bed, that can also provide orientation light at night. 3 Reading light. 4 Patient control: providing choice for the patients of 3 pre-set light colors for the cove, as well as reading light dimming control. ContemporaryTechnology(M.arch-Health care architecture) 19
  20. 20. ContemporaryTechnology(M.arch-Health care architecture) 20 DESIGN CONSIDERATIONS • System flexibility must allow for the patient to have individual control with additional switching locations for the healthcare professional. • Glare or excessive brightness must be eliminated in these spaces. • Light trespass during sleep hours must be controlled to minimize exposure that can alter circadian rhythms. • Nighttime monitoring and observation should be conducted with minimal disruptions (subdued red-amber light sources appear to positively affect melatonin). • For good rendition of skin and tissue, a CRI of 80 or higher is recommended. DESIGN VERY IMPORTANT CONSIDERATIONS: • Color Appearance • System Control & Flexibility • Modeling of Faces & Objects • Surface Characteristics • Horizontal & Vertical Illuminance Levels • Reflected Glare • Light Distribution on Surfaces • Light Distribution on Task Plane (Uniformity) • Luminance of Room Surfaces DIFFERENT OPTIONS FOR LIGHTING
  21. 21. ContemporaryTechnology(M.arch-Health care architecture) 21 • The visual requirement in the theatre is the detailed examination of tissue, organs and instruments at the site of the operation. • It is recommended that the illumination level for lighting the operating area should be between 2 000 and 10 000 lux. • Each lighting fitting should be capable of separate switching, to enable the individual requirements for special operations to be met. OPERATION ROOMS DESIGN CONSIDERATIONS • Switching and dimming controls should be considered for these areas. • Luminaires recessed into the ceiling must be gasketed and UL listed for damp locations. • Luminaires should meet the requirements for Electromagnetic Interference/Compatibility (EMI), Radio Frequency Interface (RIF) and also MIL-STD 463 E. • Reflective glare can be compounded if inappropriate finishes are selected for these areas. • High intensity recessed fluorescent luminaires can control ceiling surface glare and also provide the recommended illuminance levels on various task planes and surfaces. • High color rendering lamps are recommended in the most critical care areas; 85 - 95 CRI should be specified for general lighting.

  23. 23. IMAGING The Ambient Experience solution can include the following elements: 1.A ceiling projector displays videos or animations chosen by the patient from a library of themes, distracting them from the equipment and procedure 2.Rounded corners suggest additional space and discourage clutter 3.Soothing audio is added to create a relaxing ambience 4.Colored LED spotlights neutralize the harsh glare of institutional lighting, while encouraging a sense of wellbeing 5.Integrated cabinets provide easy access to coils and accessories, freeing the room from clutter 6.To complete the transformation, a halo of colored light illuminates the examination roomContemporaryTechnology(M.arch-Health care architecture) 23 Magnetic Resonance Imaging (MRI), open MRI and Computer Assisted Tomography (CAT) scanning presents unique lighting demands. MRI suites, due to the intense magnetic polarity created by the diagnostic equipment, demand that luminaires be constructed of non-ferrous materials such as aluminum, brass, certain types of stainless steel and polymers preventing possible injury to the patient and healthcare technician.
  24. 24. ContemporaryTechnology(M.arch-Health care architecture) 24 DESIGN CONSIDERATIONS • Luminaire performance should be weighed against visual comfort and low brightness (glare control is more tangible to patients than the amount of light). • Fixtures that incorporate non-ferrous materials must be considered when designing MRI areas. • Ambient light levels in these spaces can be relatively low during patient treatments, 30 to 35 FC. • The lighting design should provide dimming and switching for adjusting light levels as needed. • The ability to switch fixtures on and off is necessary to control general light level for activities such as patient transfer onto radiology tables. • X-ray viewing and documentation requires dimming general room lighting during viewing but also requires increased light levels for certain tasks.
  25. 25. ContemporaryTechnology(M.arch-Health care architecture) 25 Design Considerations • Switching and dimming controls should be provided. • Recessed indirect/direct luminaires with additional lighting for reading also works well in these spaces. • General lighting in shared activity areas for children should be designed with illuminance intensity levels adjusted for the floor and lower wall surface, as children tend to play or sit on the floor. • Lighting in play areas and adjacent corridors should provide adequate illumination to extend field of views. • Choose luminaires that feature color options as well as unique design elements to enhance the overall visual interest in these spaces. Design Considerations • Nursery lighting design should include dimming and switching capabilities for maximum flexibility. • High color rendering lamps should be specified, 85 CRI, for recognizing color changes in the skin. • General lighting should include luminaires that deliver the appropriate glare-free light distribution patterns for surfaces and task planes. • Lighting examination areas from multiple angles helps in avoiding shadows. • Lighting requirements for these areas can range from 3-5 FC to 75-100 FC depending on the task. DIFFERENT OPTIONS FOR LIGHTING Recessed Downlights Recessed Downlights PEDIATRICS & NICU
  26. 26. ContemporaryTechnology(M.arch-Health care architecture) 26 The entrance marks the beginning of the journey for many individuals a journey that can be filled with varied emotions about the healthcare experience. As such, these areas need to be welcoming spaces. ENTRANCE /EXTERIOR DESIGN CONSIDERATIONS • During daylight hours, the lighting should meld into the building’s architectural theme. Nighttime illumination must provide appropriate light levels to allow for safe navigation. • Contrast ratios, glare and uniformity in relation to adjacent areas must be considered when designing these lighting applications. • Dramatic differences in light levels should be avoided. Light levels should be gradually increased as one enters the grounds, allowing for safe entry. • Dark sky legislation and responsible energy management must be addressed in the early stages of the lighting design process. • During times of high illumination from the sun, providing transition areas with appropriate interior light levels becomes important. Sensors and control devices can be incorporated into the lighting scheme and automation can raise and lower light levels based on daylight contribution.(1)
  27. 27. Attractiveness and well-being Against a backdrop of demographic change and an ageing population, a highly-qualified, motivated workforce is absolutely vital. Patients choose the hospital that will give them the best care. We supply the best lighting designed to enhance well-being among staff and patients by using premium lighting solutions to create a pleasant, refreshing room atmosphere. Reasons for choosing LED: – Variable light colours – Can be controlled appropriately to needs – Versatility and high lighting quality (good colour rendering, high-precision direction of light) Resulting in: – Attractive scenarios for any time of day or activity – Individuality Space and capacity Healthcare and nursing providers are constantly confronted by the problem of limited available space. Sufficient infrastructure and spare space must be kept available to cope with emergencies such as epidemics but, on the other hand, recurring costs must be kept as low as possible. Reasons for choosing LED: – Small size – Can be integrated into architecture/furniture – Individually controllable/addressable Resulting in: – Spatial flexibility – Expandability Cost savings Costs play a key role in the healthcare and nursing sector in the EU and in most international markets. These costs include, among others, the costs of qualified staff, property maintenance, operating costs and the expenses incurred during a stay in hospital. Premium lighting solutions can aid convalescence, thus shortening hospital stays, which in turn results in cost savings. Reasons for choosing LED: – Highly efficient – Maintenance-free – Easy to control Resulting in: – Energy savings and reduced CO2 emissions – Low operating and maintenance costs – Lower total costs over a system’s entire life cycle Why LED??
