The event commenced with a warm welcome by Mr Akshay R S, the Student Representative of IEEE EdSoc Kerala Chapter. Thereafter, Mr Ananthakrishnan, the webmaster of IEEE EdSoc Kerala Chapter gave a brief introduction about the speaker. The speaker, Mr. Abhinav, STEM and HAC Coordinator of IEEE EdSoc Kerala Chapter and Secretary of IEEE SIGHT Kerala Section delivered a talk on the engineering brilliance of blue light. He began by highlighting the significant contributions made by the scientific community in the field of LEDs, specifically mentioning the breakthroughs in green and red LEDs.
The focus then shifted to the engineering brilliance of blue light. The speaker emphasized that blue LEDs played a vital role in the development of lighting technology. The ability of blue light to provide efficient and long-lasting illumination while consuming minimal energy was highlighted as a major advancement. Blue LEDs enable the production of white light by combining them with a phosphor coating, thereby allowing the creation of different color temperatures for various applications.
The speaker also discussed the flip side of blue light, acknowledging concerns researchers and health professionals raised regarding its excessive exposure. While blue light offers benefits such as enhanced mood, increased alertness, and improved cognitive function, its effects on sleep patterns and eye health were addressed. The speaker explained that the high energy and shorter wavelength of blue light could cause disruptions in sleep cycles and potential eye strain.
Throughout the session, the speaker engaged the participants by showcasing practical demonstrations. Using a spectrometer, he compared the spectral characteristics of different light sources, including incandescent bulbs, compact fluorescent lamps (CFLs), and LED bulbs. The differences in energy consumption, durability, color rendering, and spectral composition were highlighted. The speaker emphasized the advancements and affordability of LED technology, making it a preferred choice for lighting solutions. The event concluded with a Q&A session, where participants had the opportunity to seek clarifications and further discuss the topics covered. The organizers also encouraged participants to provide feedback on the event through a feedback form shared in the chat. The event host Ms S Neha, the Content Writer of IEEE EdSoc Kerala Chapter ended the meeting with a pleasant farewell.
