Benefits and advantages of led lights pptPayojKatiyar1
LED lights are the need of every home. LED lights provide a wide range of advantages. It is a solid state lighting device. It works on semiconductor material which utilises much less amount of electricity. LED lights use a driver(semiconductor chip) which changes AC to DC(Alternating current to direct current). Each DC operating device utilises much less energy as compared to other AC products.
Solar cell is the device that converts energy of light directly into electrical energy (electricity) by photovoltaic effect In general, a solar cell that includes both solar and non solar sources of light
(such as photons from incandescent bulbs) is termed a photovoltaic cell. Solar cell is also know as photovoltaic cell
Most familiar solar cells are based on the effect
of photovoltaic In this effect, light falling on semiconductor device of the two layer produces a potential difference or photo voltage between the layers The voltage thus produced can drive a current through an external circuit producing useful work
the solar panels are the primary source of the solar equipment which helps in trapping the solar energy. the performance of the solar panels vary. check the types of solar panles in these slides
An Overview of Photovoltaic Systems or PV Systems. This PPT outlines what a solar systems is and what it is consisted of. From solar panels to charge controller to deep cycle batteries to the inverter.

Optimized energy efficient lighting system for green buildingseSAT Journals
Abstract
Increasing population places increasing demands on energy supply, which leads to heavy power deficiency. We can supply only a
limited amount of energy to the consumers because we have only limited conventional sources of energy and non-conventional
energy sources are mostly still under research and have not been deployed on a large scale. Not only there is limited amount of
energy to be supplied to the consumers but heavy demand of energy supply also leads to environment degradation. This creates a
need to use the limited energy efficiently. This has given rise to new trend towards reducing the energy consumption: Green
Buildings. About 40% of the energy consumption in the world is consumed by buildings [1]. Energy consumed by lighting systems
accounts for about 15% of total energy consumption of buildings [1]. Thus we need to use energy efficient lighting devices for
illuminating buildings. Thus in this study we to tend to develop optimized energy efficient system, which will use LED lights to
illuminate buildings. The illumination intensity of the LED lights will be decided by the FPGA, which is interfaced to the LED
driver. Based on combined values of light intensity of the room and occupancy of the room using different sensors, the light output
of the LED will be controlled.
Keywords: LED Lighting System, FPGA, Green Buildings, Auto-dimming.
This paper discusses the principle of operation, dynamic modeling, and control design for light-to-light
(LtL) systems, whose aim is to directly convert the sun irradiation into artificial light. The system discussed in
this paper is composed by a photo- voltaic (PV) panel, an LED array, a dc–dc converter dedicated to the
maximum power point tracking of the PV panel and a dc–dc converter dedicated to drive the LEDs array. A
system controller is also included, whose goal is to ensure the matching between the maximum available PV
power and the LED power by means of a low-frequency LEDs dimming. An experimental design example is
discussed to illustrate the functionalities of the LtL system.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

3. Introduction
According to a Press Information Bureau (PIB) announcement, by
2019, 770 million LED bulbs and 35 million LED streetlights will be
deployed to replace conventional lights.
Over 2.1 million conventional streetlights have already been replaced
with LED streetlights across the country, under the Street Lighting
National Programme (SLNP).
The installation of LED streetlights has resulted in annual energy
savings of 295 million kWh and reduced carbon emissions by
2,30,000 million tonnes annually. The project has been implemented
across 23 states and union territories.

Most modern LED operate in a range of 2 to 4 volts and consume
anywhere between 350mA and 1500mA.
Power consumption of LED light bulb is only 10% of the standard
light bulb.
LED light bulbs withstand great amount of vibration, shock and
temperature variations.
LED light bulbs are 10-60 times more energy efficient than
incandescent light bulbs.
Incandescent light bulbs produce light that flickers whereas LED light
bulbs produce flicker free light.
LED bulbs can produce many rich and vibrant colors when compared
to incandescent light bulbs.
How LED Saves Energy ?????
9. 9
Smart connected LED lights: Lighting systems will get smarter, as the
possibility of autonomous, self-commissioning illumination systems is
emerging.
Changes in ‘on board technology’: This will also reduce the number of
components compared to those used in traditional drivers. Use of fewer
components can reduce costs while enhancing the efficiency of the final
product.
Use of Chip Scale Packaging (CSP) technology: This will enhance
lumen output and also increase the reliability of the final product.
Introduction of driverless low voltage direct current (LVDC)
operated products: This will enable energy saving by reducing AC-DC
current conversion losses.
