It involves an electronic circuit and software system that provides this. PREVIOUS TECHNIQUE LEDs (light-emitting diodes) produce a range of colors when an electric current is applied. It is an electronic component that emits light. LEDs are popular because of their low cost and wide spectrum. a wide range of wavelengths from the ultraviolet (UV) region to the near infrared (IR) region They can be produced within this range, a narrow emission band (approximately 5–10 nm), and per surface area. advantages such as high light intensity (capable of reaching levels of hundreds of mW / cm²) Thanks to this, it has become an effective alternative to laser systems. Furthermore, LED arrays... It can be produced in different sizes to accommodate large spaces and works Because they do not emit significant levels of heat during operation, they reduce the risk of damaging surrounding tissue. It reduces. Healthcare-associated infections (HAIs), or commonly known as hospital infections, are a type of medically related infection. infections, during the incubation period when patients are hospitalized. These are infections that develop after hospitalization, despite advances in medicine. STIs (Substantial Obstructive Pulmonary Disease) remains a significant problem both in our country and worldwide. It continues. These types of infections lead to a longer treatment period for patients, and to complications during treatment. increase in costs and consequently in morbidity and mortality rates This is the reason. The widespread use of modern treatment methods has increased life expectancy. With the prolongation of illnesses and the increase in invasive medical interventions, the importance of SSIs (School-Based Immunotherapy) has further increased. This has become evident. SBIE is a critical factor that directly affects the quality of healthcare services. This parameter can negatively affect treatment outcomes. Treating microbial infections with light is not a new approach. It was first used in 1903. Niels Ryberg Finsen, who was awarded the Nobel Prize in Medicine, developed a treatment for lupus vulgaris. It is known that light is used. Similarly, in the past, infectious disease patients Attempts were made to achieve healing by exposing the patient to direct sunlight; this The practices have been shown to reduce influenza-related morbidity and mortality rates, and 1 Sunlight has been reported to be effective in reducing the transmission of infections from person to person. Patients exposed to light have a higher incidence rate compared to patients treated indoors. It is also stated in the literature that it heals quickly. In this context, LED technologies that emit light at wavelengths close to daylight... Recent studies have examined its usability for microbial disinfection purposes. This trend has been increasing over the years. Specifically, white and blue LEDs have a certain intensity and It has been shown that it can produce lethal effects on pathogenic organisms over time, and These types of systems offer a low-cost, safe, and sustainable disinfection method. Its use in the healthcare sector has begun to attract interest. THE PURPOSE OF THE INVENTION The invention deals with bacteria, viruses, and fungi found in indoor air and on surfaces. Aimed at eliminating pathogenic microorganisms, using a wavelength of 430–680 nm. The invention relates to an LED-based disinfection system operating within a specific length range. The DLED (Disinfection LED) system developed within this scope uses white and blue LEDs. by creating oxidative stress in the cellular structures of microorganisms with which it works with a mechanism that prevents them from multiplying and causes cell death He is working. The primary aim of the invention is to reduce morbidity and microbial contamination. The aim is to contribute to reducing mortality rates. Current UV-C light... the negative health effects of these systems (e.g., carcinogenic potential) are considered When considered in this context, DLED systems that operate in the visible light spectrum are more...
