What is the actual different between light of different colours?
The difference between light of different colours is the frequency of the electromagnetic wave that it makes. Each different colour of light has a different frequency and amount of energy that it gives off, as the frequency decreases so does the energy which is why we see each colour differently. Electromagnetic waves are a form of energy absorbed and made by charged particles which travel in a wave like shape which forms the light. Each different colour of light has a different sized wavelength which makes them individual to each other. For humans the range of visible wavelengths is from 400 to 700 nanometers as light. For example the visible blue light has a wavelength of about 475nm, because the blue wavelengths are shorter in the visible spectrum, they are scattered more efficiently by the molecules in the atmosphere.


Define the following lighting terms: ambient light, direct light diffuser, luminosity, energy efficiency, and watts.

Ambient light: The soft indirect light that fills the volume of the room with illumination.
Direct light diffuser: A light fixture, such as a frosted globe, that spreads light evenly.

Luminosity: The condition or quality of being luminous.

Energy Efficiency: Energy conversion efficiency is the ratio between the useful
Output of an energy conversion machine and the input, in
Energy terms.

Watts: The watt is a derived unit of power in the International System of Units.
A unit of luminous power equal to the luminous power of light of a single wavelength.


Comment of Global Warming.
Global warming is caused by what is called the greenhouse effect. This means the suns solar radiation is being trapped in the earth’s atmosphere by gases such as carbon dioxide and methane. Which once have come in it is impossible for them to get back out, which result in our earth heating up, causing a lot more problems for our generation. If global warming continues it will continue to melt the ice caps and raise the oceans which cause low lying islands to be destroyed and disappear. Even though people cannot stop everything that is making our earth worse they are at least trying to improve it by using less polluting knowledge and technology to make the earth a lot cleaner and safer for people, animals and plants. Although the oxygen levels may decrease due to global warming putting our breathing at risk and making it really difficult for plants to photosynthesis and help the human race to live on. There are ways we, ourselves, can improve the way we live to help the earth and the people on it and slow down global warming. This is a part of what they teach us in design futures engineering in different ways that we can help and contribute to decreasing global warming.

How can the modern home become more energy efficient with regard to lighting?
The modern home is where we spend most of our time which means we would use the most amount of energy there. The common everyday things that we use or do that use a lot of energy is electricity, such as water and lighting around the house and heating such as anything we use to prepare foods or heat the house during cold seasons. It has been known that people are using way too much energy in the modern household for unpractical things such as using unneeded light and leaving power sources on when they aren’t being used. Companies are trying to make their products better by making them more energy efficient and cutting down on using electricity, by installing windows instead of fans or solar panels which use the suns light and heat and turns it into energy. The little things that people can do to make their household more energy efficient is turning off lights when you’re not in the room or even using candles instead of lights. Also having a fire place instead of actual electricity heating. By doing these small things you will be making a big problem easier to solve.

Research a modern day lighting designer and comment on their contribution to the design world.
James Clar in his early work dealt with analyzing how technology and media work but after he moved to the Middle East it shifted his focus to how technology and media affect. Clar studied film as an undergraduate at New York University focusing on 3D animation. Then continued on to his masters staying at NYU Interactive Telecommunications Program. It was then that Clar moved away from the screen and started working directly with light and creating sculptured lighting pieces. He developed his own system and found he could create unique visual displays. At the beginning of 2011 Clar opened ‘Statellite’ in Dubai, a warehouse space that allows him to build bigger and better sculptured products. Also allowing the public to come and see his finished works and artistic process. Some of Clars achievements include three patents in the US for new engineering systems created while developing his light art work. His artwork has also been included in the Chanel Mobile Art exhibition (Tokyo), The New Museum of Contemporary Arts (New York), The Chelsea Art Museum (New York), The Somerset House (UK), Museum on Seam (Jerusalem), and LV Gallery (Hong Kong).
