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.

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

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.

7. LIGHTING IN HOSPITALS…………………...AN INTEGRATED APPROACH
• The occupancy of hospital is quite varied and very dynamic.
• Lighting need for every occupant is very different from the other, and sometimes even conflicting.
• Physical and visual environment of hospitals impacts the psychological senses of the patient, the staff and the relatives.
• Efficiently designed lighting system satisfies the visual, biological and emotional needs of the user, and caters to
different dimensions of the human needs.
• Affects biological activity of a person, influencing body functions, concentration and creating relaxed environments.
• Certain 24 x7 areas of hospitals adds significance to the lighting design and lends criticality to the illumination planning
of hospitals.

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. 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.

• 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. 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. 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.

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.

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. 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.

cove, as well as reading light dimming control.
ContemporaryTechnology(M.arch-Health care architecture) 19

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

• 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. 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)

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. 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. 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.

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. 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
