LED Panel Lights: The Preferred Solution for Hospital Lighting

The right hospital lighting design plays a crucial role in providing visibility, enhancing color rendering, minimizing glare, promoting patient well-being, and improving staff efficiency.

So, what kind of lights can meet the lighting needs of modern hospitals? In this article, we will delve into the key requirements of hospital lighting design, and the respective characteristics of traditional lighting and LED panel lights. Understanding this knowledge can be a comprehensive reference before purchasing hospital lighting fixtures.

Key Requirements for Hospital Lighting

Hospital lighting environments need to meet stringent requirements to ensure optimal patient care and staff efficiency. The specific requirements for hospital lighting design are:

Illuminance Requirements

Recommended Values for General Lighting in Hospitals
Room or PlaceReference PlaneIllumination(Lux)UGRRa
Operating Room0.75 m Height7501980
Laboratory, Pharmacy0.75 m Height5001980
Treatment Room, Examination Room0.75 m Height3001980
Nurse's Station, Monitoring Room0.75 m Height3001980
Waiting Rooms, Registration Halls0.75 m Height2002280
Wards, WalkwaysGround Level1001980

The above illuminance requirements are based on the entire room and do not specify localized illuminance requirements. However, in actual cases, we have found that a stepped, scenario-based illuminance distribution is more in line with the needs of a hospital lighting system. In reference to the Lighting Association of North America (IESNA) published “IES HANDBOOK” listed in the recommended illuminance values, we categorize the gradient and scene of the illuminance distribution of two cases:

Stepped Illuminance Requirements for A Room

For example, in the hospital’s common entrance hall, registration hall, consulting desk and other areas of the work desk surface illumination can be increased to 300 lux ~ 750 lux, and the general area of the ground during the day can be up to 200 lux, the family rest area ground 100 lux.

The use of an illuminance ladder on the visitor’s vision to assist in the guidance, to serve the patient and family members of the medical requirements.

The illuminance demand of different periods in the room

in the examination room, for example,there are two common scenarios of doctors talking to and examining patients. The illuminance value they need is 300~500 lux in the IES recommendation and 1000 lux on the working surface during local inspection.

Inside the ward, there are also doctors checking and night observation, of course, there are also patients reading, entertainment, and other life scenes. These corresponding to the work surface and illuminance level are not the same, lighting design needs to be considered differently.

Human-centric and Smart Lighting Requirements

Reduce unnecessary glare during medical treatment

Especially in medical elevator halls, wards, walkways to operating rooms, examination rooms, and other areas involving patients in supine positions. These areas need to reduce or avoid installing luminaires that cause significant glare. Diffuse luminaires or indirect light-emitting luminaires such as LED panel lighting is recommended.

Increase the need for patient privacy and personalization

For example, in a multi-person room, the use of drapes ensures patient privacy but also increases the complexity of luminaire control. Luminaire control needs to satisfy both the overall medical lighting requirements and the patient’s need for light control of the personal space within the drape.

Intelligent Lighting Requirements

  • Installation of human infrared sensors to control lamps in areas where it is not appropriate to manipulate switches by hand, such as medication rooms, locker rooms, and soiled rooms.
  • Use RGB LED panel light as auxiliary lighting in CT rooms, MRIs and other confined spaces to relieve patient anxiety.
  • Adopt variable color temperature and dimmable features in inpatient wards where there is a lack of daylight. Simulating natural light, helps patients to regulate their biological routine.

Energy Saving Requirements

Lighting power expenditure has been the main part of hospital power consumption. From the current development of lamps, using high luminous efficiency lamps, reasonable light distribution design, and intelligent control is an effective program to reduce power expenditures. The following are recommended limits for hospital lighting power density:

Recommended Limit Values for Hospital Lighting Power Density
Room or PlaceIllumination Value (lux)Lighting Power Density Limit (w/m²)
Laboratory, Pharmacy500≤13.5
Treatment Rooms, Nurses' Stations300≤8
Waiting Rooms, Registration Halls200≤5.5
Wards and Walkways100≤4.5

Disadvantages of Traditional Lighting in Hospital

Uncocomfortable Environment

Traditional hospital lighting has primarily used grid fluorescent lamps, and some older hospitals may still be using compact CFLs. These lights were configured 20 years ago and do not meet the current needs of patients and staff in these areas of comfort, visibility, and glare.

Low Lighting Uniformity and Color Rendering Index

Whether it’s a grille lamp or a regular compact CFL, they have inherent limitations in lighting uniformity. If the lamps use cheap three-color phosphors, the color rendering index will also be lowered. Uneven illumination and low color rendering index can easily cause visual fatigue.

Low luminous efficacy leads to high energy consumption

Traditional fluorescent lamps or CFLs have a luminous efficacy of less than 85 LM/W. As a result, certain localized lighting in hospitals often requires high-power lamps to achieve the required illumination levels.

Energy-intensive lighting is a major part of a hospital’s electricity consumption, which may have been the norm 20 years ago. The chart below shows the U.S. Department of Energy’s Energy Information Administration‘s (EIA) statistics for healthcare building electricity consumption at that time, with lighting accounting for 42%.

LIGHTING CHARGE

Frequent Maintenance Requirements

The theoretical lifespan of traditional CFLs is 5,000 to 8,000 hours. If non-tri-color powder lamps are used, the light decay will be faster, and therefore the lifetime will be shorter. Obviously, frequent replacement of bad lamps will increase the operating costs of the hospital.

The Preferred Solution: LED Panel Lights

The field of hospital lighting has undergone a groundbreaking transformation with the advent of LED ceiling panel light. These innovative lighting solutions offer countless benefits, ranging from creating a soothing environment for patients to improving illumination during medical procedures. Next, we’ll take an in-depth look at the benefits LED panel lights bring to hospitals.

Enhanced Patient Experience: Creating a Soothing and Comfortable Environment

Hospitalization can cause a variety of stresses such as pain and anxiety. An unsuitable light fixture such as a harsh chandelier can exacerbate these stresses. At this point, a calming atmosphere is needed to relieve this stress. Edge-lit LED panel light excel in this area, providing soft, diffused lighting that minimizes glare and shadows. The even distribution of light creates a soothing environment for the patient, promoting relaxation and aiding the healing process.

Additionally, the intelligent LED flat panel light also has built-in dimmable and color temperature adjustments to mimic natural daylight, further enhancing patient comfort.

Below is a specific main lighting scheme:

In the ward, 4 pcs 60 x 60 cm (2’ x 2′), 36-watt dimmable LED panel lights were installed in the ceiling to provide overall illumination. The lamps can be adjusted for the desired illuminance values, from 100 to 500 Lux.

Uniform Light Distribution

The edge-lit ultra thin LED panel light provides excellent light quality and uniformity, ensuring consistent brightness throughout the room. This is due to its light guide and diffusion panel that evenly disperses and softly directs the LED light source. It is worth noting that direct-emitting panel lights may not meet this high requirement. This enhanced visibility allows healthcare professionals to perform procedures accurately, reducing the risk of error.

The photo below shows 16 pcs 30 x 120 cm, 18-watt edge-lit ultra-thin LED panel lights installed in the ceiling to provide overall illumination.

Treatment Rooms lighting

Accurate Lighting

The color rendering index is an important parameter for accurate lighting. In the operating room or treatment room, accurate lighting is critical for medical procedures and examinations.

The color rendering index (Ra) refers specifically to the degree to which an object reproduces its true color when illuminated with a certain light source and when illuminated with a standard light source (usually sunlight). The higher the color rendering index, the higher the true color reproduction; the lower the color rendering index, the greater the color difference.

The color rendering index (CRI) of our panel light is above 80, and some customized models have a CRI above 95. A high CRI allows for accurate color perception, which is important for tasks such as vein detection and distinguishing tissue types.
