Hospital Lighting Solution
As a place to heal the wounded and rescue the dying, hospital needs to create a capacious and comfortable atmosphere, as well as bringing about a neat and quiet environment, in order to give full play to the function of the hospital and the impact on health directly or indirectly.
Therefore, lights need to be chosen differently according to different functions of hospital. In many cases, the medical staff must observe and judge the appearance of the patient’s skin color before making the correct diagnosis. In addition to ensuring the normal use of lighting in 24 hours , the demand for lighting is different in different areas. And in any situation, the hospital should pay special attention to imposing restrictions on the glare.
Hospitals are required to ensure the stable lighting in 24 hours, without holidays and festivals throughout the year, with a high requirement for lighting,as a new type light source, LED is easy to satisfy the almost harsh lighting requirement in hospital for its proper design and high cost-performance of energy retrofit.
Advantage of LED lighting solution
Environmental protection and energy saving: No mercury, no pollution, no ultraviolet (uv)radiation. LED saves up to 50% of energy more than CFL , and 80% more than incandescent bulb giving with the same brightness.
High efficiency : adopting the high-efficiency LED chips, luminous efficiency of lamps can reach 80 Lm/W.
Low lumen decay, long service life: the average service life is up to 25000 hours, Light failure is far lower than the traditional lights.
Quick cost recovery: Recoup the cost within a year and a half after renovation.
Wide range of color temperature: almost can provide not only any color temperature, but also light with any color such as red, green and blue.
High color rendering index: CRI>80.
Easy to install, safe and reliable: adopt the built-in type isolation power supply, just replace the original fluorescent tube with the LED fluorescent tube, remove the ballast and starter and change the circuit chart slightly.
