Thus, the user can... Standard AC 220V mains connection without the need for additional professional installation. through both general lighting and continuous air and surface disinfection 15 It can provide. The invention uses a polycarbonate structure with a translucent (opal) upper half and an opaque lower half. The diffuser cover (1) ensures that visible light is spread evenly throughout the environment. Over time, it also helps protect the internal components from the external environment. Diffuser cover (1) The top LED ring MCPCB (2) located under the tunable white (3000K-20 It features a combination of 6500K, 405 nm UVA and outward-facing 275 nm UVC LEDs, Thanks to this structure, both general lighting and surface lighting can be achieved through the same optical system. The hygiene function can be performed. The light from the LEDs on the upper LED ring MCPCB (2) is controlled. 25 vacuum metallization coated polycarbonate diffuser cover (1) for the purpose of directing it. Parabolic reflector (3) in plastic injection molding is used. Wide mouth The lighting is achieved thanks to this structure, which is in the form of a reflective cone with a narrow base pointing upwards and downwards. Efficiency is increased and light distribution is optimized. The fundamental technical problem that the invention aims to solve is the transmission of UVC rays to the external environment. The goal is to disinfect the air without allowing it to leak. This includes indoor 30... 275 nm UVC located inside the UVGI chamber (4) with surface coated with Al-MgF₂ Air disinfection in enclosed spaces is achieved with the help of LEDs. UVGI 3 aluminum labyrinth with zigzag geometry made of cast aluminum surrounding its chamber (4) air ducts (5) allow air passage while preventing UVC rays from leaking into the outside environment. It physically blocks access. Thus, the system is leak-proof, which increases user security. It creates a UVGI architecture. The aluminum heat sink (6) included in the invention is press-fit for the UVGI chamber (4) 5 It is a thermal management element with radial fins, where it is located, and it has both UVC on the inside. the lighting LEDs on the LEDs as well as the upper LED ring MCPCB (2) It ensures that the heat it generates is efficiently transferred to the external environment. Thus Long-term and stable operation is achieved within a compact design. The main driver PCB (7) contains the LED driver circuits, the microcontroller unit (MCU) and 10 A hardware fail-safe safety relay is included, ensuring the system's safety and uninterrupted operation. The operation is ensured. In addition, the mmWave radar located inside the sensor module (9) And thanks to PIR sensors, the presence of people or pets in the environment can be detected. In case of detection, UVC radiation is reduced to 50 via a hardware safety relay. User safety is increased by interrupting the process in less than a millisecond. 15 Ventilation slits located on the outer shell (8) which protects the internal components and Thanks to the sensor windows, both air circulation and the sensor module (9) It is possible for the system to function properly. The system has a UVGI chamber (4) in night mode. While performing air disinfection with its internal UVC LEDs, the upper LED simultaneously... Surface sterilization using outward-facing UVC LEDs on ring MCPCB (2) 20 It can provide continuous hygiene support with 405 nm UVA light during the day. It can offer standard lighting thanks to its adjustable white light mode. Its function is also being fulfilled. In these aspects, the innovation offers a compact design, multi-mode operation, and a leak-free UVGI architecture. Advanced safety system, standard sensor compatibility and integrated thermal management 25 It creates an innovative solution that offers these advantages all in one. Method of Implementing the Invention The working principle of the invention is based on the ambient conditions detected by the sensor module (9) 30 different operating modes of the microcontroller (MCU) on the main driver PCB (7) It is based on the principle of commissioning. 4 General Lighting Mode: When the sensor module (9) detects motion in the environment and the environment If it is dark, the main driver PCB (7) has a tunable white LED ring on the MCPCB (2). It powers LEDs (3000K-6500K). The light produced is directed by means of a parabolic reflector (3). The polycarbonate diffuser cover (1) diffuses into the room. Day Mode (When People Are Present): During hours of high human traffic, the white LEDs are activated at 5. Additionally or independently, 405 nm UVA on the top LED ring MCPCB (2). The LEDs are activated. This mode provides a continuous, low-dose light on surfaces with a wavelength of 405 nm. It creates a hygienic effect. Night Mode (No People Present): Sensor module (9) (mmWave + PIR) detects people or humans in the environment. When it confirms there are no pets, the system automatically switches to night mode. This 10 In this mode, two processes occur simultaneously: First, 275 nm inside the UVGI chamber (4). UVC LEDs are activated. Through the ventilation slits (8) in the outer casing. The incoming ambient air is filtered through aluminum labyrinth air ducts (5) to UVGI It reaches the chamber (4). Here the air is disinfected and then goes out again by natural convection. It is discarded. Aluminum labyrinth air ducts (5) allow air passage thanks to their zigzag structure. It physically prevents UVC photons from leaking out while emitting them. Secondly, the upper LED The outward-facing 275 nm UVC LEDs on the ring MCPCB (2) are activated, illuminating the room. It sterilizes the surfaces. When any movement is detected, the main driver PCB (7) The hardware relay on it cuts off the UVC power in under 50 milliseconds, ensuring complete safety. It provides. The heat generated during this entire process is expelled through the aluminum heat sink (6). 20 The invention is not part of a larger structure; it is a standalone, independent, and integrated system. It is a smart LED bulb device. Suitable for standard lighting fixtures (chandeliers, lampshades, etc.) with E27 socket. It is used by attaching it via the base (10).
