Why LED healthcare lighting Offers Better Illumination
Healthcare facilities and hospitals use lots of energy to ensure that patients, their visitors, and staff enjoy a comfortable and safe environment. Energy bills in the healthcare industry can be high especially in facilities that run round the clock. As a result, many facilities are adopting LED technologies to reduce operational costs, increase revenue, and enhance efficiencies. In this article, we shall discuss the importance of LED lighting in the healthcare sector.
Technology is Advancing
In the past, fluorescent and incandescent light bulbs were the go-to light source for many healthcare facilities. However, as hospitals and LED technology evolves, warm human-based illumination is fast replacing flickering blurred lighting.
The change to LED healthcare lighting allows these facilities to offer enhanced services to their patients. It also cuts down energy and maintenance costs. This way, hospitals can invest these resources in people instead of replacing bulbs. Here is how LED lighting offers enhanced illumination.
Circadian Rhythm and Color Temperatures
LED lights to come in different shades of white, also known as a light fixture’s CCT (correlated color temperature). CCT is computed in Kelvin (K), which is comparable to degrees Celsius. Varying conditions on the Kelvin scale display different colors. For instance, the light between 2000K and 3500K appears more yellow or orange and is defined as warm white or ultra-warm.
As the temperature in Kelvins increases the color becomes paperwhite, also described as neutral or natural white. In this case, it would measure up to 5000K. The color then changes into blue-white, also known as cool white.
Across the day, light transforms from warm white at daybreak to natural white, before changing again in the afternoon to cool white. The color changes once more to natural white before transforming to an ultra-white warm color at dusk. Human bodies are used to this light cycle.
Artificial lighting that veers from the cycle of natural lighting can confuse human rhythms. According to the National Institute of General Medical Sciences, “Circadian rhythms are physical, mental and behavioral changes that follow a roughly 24-hour cycle, responding primarily to light and darkness in an organism’s environment.” Studies show that different lighting types prompt different physiological effects. White/blue light compared to the bright light in midday restrains melatonin while increasing serotonin. This type of light is ideal for the activity. On the other hand, orange/red light stimulates melatonin as humans prepare to go to bed.
With proper balance, the human body generates serotonin, dopamine, melatonin, and cortisol in adequate quantities at the appropriate time of the day. According to some researchers, lack of circadian rhythms can trigger illness, irritability, or sleeping disorders.
Many LED lighting options can be dimmed, which makes them ideal for use in hospital and healthcare settings. Color transforming red, green, and blue LED lights and changeable color temperature fixtures are available. These lights can be ideal in CT and MRI scan spaces. They promote a relaxing environment that gives patients something to focus on and stay calm. Remember, color temperatures influence how your body operates. Researchers opine that:
“By controlling the circadian system, light—both natural and artificial—impacts many health outcomes among patients and staff in hospitals such as depression, sleep, circadian rest-activity rhythms, as well as the length of stay in the hospital.”
The use of occupancy sensors is another excellent LED healthcare lighting regulatory method. Sensors save you money and also prolong the life-span of your bulbs by switching them off when no one is using them. These sensors are ideal for low-traffic spaces.
No Health Risks
Fluorescent bulbs come with mercury that can be discharged should the bulb break. Mercury is not only toxic, but it can be dangerous when inhaled or absorbed via the skin. To cut down the possibility of risks, the Environmental Protection Agency recommends some cleanup procedures like opening windows and doors, vacating the room, and switching off air conditioning and heat systems.
LED lighting doesn’t contain mercury, and they produce little to no UV radiation. These features make them ideal for use in healthcare facilities and hospitals. LED lights don’t discharge color spikes or even flicker.
Color flickering and changes can trigger negative effects like dizziness and headaches. If used for healthcare lighting, LED fixtures and bulbs can enhance general health while reducing the chances of suffering health risks that incandescent and fluorescent bulbs cause.
It is evident why LED lights are ideal for use in healthcare facilities. They offer color-rendering guides, color temperatures, and regulation options the healthcare facilities require. They also help institutions save money and ensure that patients are handled without annoying interruptions.
