“…During the last years, the furtherance of LED technology led to playing a crucial role in the day-to-day life of the human (Lin et al, 2019). This solid-state device is highly efficient, reliable, and durable over the other forms of the lighting system, which results in the rapid growth of the LED industry (Soh et al, 2017). Producing light by LED varies from other conventional lighting systems because it is a semiconductor diode (Soni, and Devendra, 2008).…”

The light-emitting diode (LED) is an advanced technology with a wide range of applications in our day-to-day life. It has numerous advantages over conventional light, such as controlling the spectrum of light, the specificity of the wavelength, cool emitting surface, and cost-effectiveness. The novel technologies and developments have proved the efficacy of LEDs in eliminating microbes rather than being an effective lighting source. The LED employs Photodynamic Inactivation to eliminate micro-organisms with the help of various photo-sensitizers. Photodynamic inactivation is a non-chemical based technique that helps fight against the microbes without developing the resistant microbial strains. The illumination of LED at a specific narrow wavelength exhibits antimicrobial activity against a wide range of microbes, including resistant strains. Getting rid of harmful micro-organisms is one of the effective ways to reduce health risks and promote quality of life. Hence, the LEDs with specific narrow wavelengths can be employed to sterilize the medical equipment, healthcare environment, and food preservation without using chemicals. The Photodynamic Inactivation using LED as a light source will be a promising source for eradicating harmful micro-organisms, including nosocomial and foodborne pathogens.

Light-emitting diodes (LEDs) are solid-state devices that are highly energy efficient, fast switching, have a small form factor, and can emit a specific wavelength of light. The ability to precisely control the wavelength of light emitted with the fabrication process enables LEDs to not only provide illumination, but also find applications in biology and life science research. To enable the new generation of LED devices, methods to improve the energy efficiency for possible battery operation and integration level for miniaturized lighting devices should be explored. This paper presents the first case of the heterogeneous integration of gallium nitride (GaN) power devices, both GaN LED and GaN transistor, with bipolar CMOS DMOS (BCD) circuits that can achieve this. To validate this concept, an LED driver was designed, implemented and verified experimentally. It features an output electrical power of 1.36 W and compact size of 2.4 × 4.4 mm2. The designed fully integrated LED lighting device emits visible light at a wavelength of approximately 454 nm and can therefore be adopted for biology research and life science applications.
