LIGHTING IN HEALTH INSTITUTIONS Led Lighting solutions in Health Institutions should meet individual needs under changing conditions. There are high expectations for patient comfort, staff productivity, efficient energy usage and quality lighting solutions. Therefore, lighting system plays an important role.

Hospital corridors, patient rooms and clinics should be equipped with necessary lighting systems to fulfill required functions. In this scope design limits are defined under EN 12464-1 ITS EN 12464-1) standards. Apart from these, using light sources with lighting uniformity and necessary color temperature is highly essential.

COLOR RENDERING INDEX Color rendering index (CRI) of a light source is a measurement which shows how the light source illustrates real color. It is a scale from 0 tolOO and color rendering increases when the value goes to 100. A light source with value of Ra = 100 reveals all the colors optimally as under a reference light source CRI is critical in hospitals especially places such as operating rooms, examination rooms, intensive care units and laboratories. CRI should be 90 in these premises.

FIXTURE EFFICIENCY LIGHT OUTPUT RATIO It is the ratio of luminous flux of lighting fixture to luminous flux of light source. Luminaire design plays crucial role for modifying and directing the highest value of the light source. EFFICACY Here, Im/w value must be taken into consideration. A first class lighting fixture design should provide both energy savings and quality lighting to the end user.

By using products with high efficacy it is possible to get same light flux by using less lighting fixtures or consuming less power with the use of automation there can be a 40% or more saving. If there is a proper selection of lighting products and matching lighting design for the places, there will be a sufficient amount of lighting fixtures and more energy saving. Misguided lighting designs might cause economic loses to the hospital and decrease the life quality of the patients.

For lighting patient rooms, implementing a variable lighting system provides right healing zone for the patients. Smart lighting systems are essential for the patient comfort and efficiency. These systems also help to benefit from daylight. For patient rooms, necessary light quality and lighting levels has to be achived for examination and medical support. There must be night lights for patients for their security. Comfort is a huge matter in patient rooms. There must be products with low UGR and control systems that aiming functionality. For clinical requirements, support lighting...

COMMON AREAS There has to be a homogenous light source which is not causing discomfort on the sight of the patient and accompanying people. CRI>80 and 3000K should be preferred. *G6060EPB - Because of its indirect design, light source is invisible and by this way no glare occurs. *G60600PL - Because of its opal prismatic design, it gives more homogenous light distribution and glare rate is low. With its 92% transmissivity, lighting is quite efficient. MOM BED SETS There must be a 1000 lx of illuminance during examination. For that reason lighting fixture with the high efficiency must be...
