ASSIGNMENT QUESTIONS:

1.WHAT IS THE ACTUAL DIFFERENCE BETWEEN LIGHT OF DIFFERENT COLOURS?

The frequency of the EM wave determines the amount of energy it contains. Therefore, different colours of light have different frequencies and amount of energy

2.DEFINE THE FOLLOWING LIGHT TERMS:

• AMBIENT LIGHT- The soft indirect light that fills the volume of a room with illumination.


• DIRECT LIGHT DIFFUSER-A light fixture, such as frosted globe, that spreads light evenly.


• LUMINOSITY-The intrinsic brightness of a celestial object (as distinct from its apparent brightness diminished by distance)


• ENERGY EFFICIENCY- Percentage of total energy input to a machine or equipment that is consumed in useful work and not wasted as useless heat.
  
  
• WATTS- The watt (symbol W) is a derived unit of power in the international system of units.

3. COMMENT ON GLOBAL WARMING:

Global warming refers to the rising average temperature of Earths atmosphere and oceans which apparently increase Global temperature, this will cause sea levels to rise and will change amount and pattern of precipitation/rain, and a probable expansion of subtropical deserts. Global Warming is caused by many things one of the main source of pollution/green house gases by the way is very relevant to the topic we are learning about which is Electricity. Electricity pollution is.......

• turning on a lamp


• turning on the t.v


• using the air conditioner


• playing on the computer


• heating a meal in the microwave etc.

The main point i am looking at is turning on a light. Turning on a light can supposedly cause green house gases which are then forced into the air creating electrical pollution. Some people today are creating lights that are energy efficient which can reduce the amount of pollution that goes up into the air.

4. HOW CAN THE MODERN HOME BE

COME MORE ENERGY EFFICIENT WITH REGARD TO LIGHTING?

As i said at the bottom of question 3 some

people are making lights that are energy efficient

This means that their is less energy emitting from from a lamp or light. Types of bulbs can change how much energy is used as well. The two types of bulbs i am focusing on is the fluorescent light and the incandescent light. In the Table below shows the comparison of these two lights when used when looking at green house gases, power, purchase price, expected operating hours and electricity running costs per year approx.

In Modern day housing it would be better to install fluorescent lights rather than your everyday bulbs ( incandescents) to become more energy efficient.

5. RESEARCH A MODERN-DAY LIGHTING DESIGNER AND COMMENT ON THEIR CONTRIBUTION TO THE DESIGN WORLD.

KEVIN ADAMS.....

Kevin Adams is an American theatrical lighting designer.He has earned three Tony Awards for lighting design. Adams grew up in Texas and attended the University of Texas where is received a B.F.A in scenery design then attended the Califonia Institute for the Arts where he recieved a masters degree. He also worked as a set deigner at various theaters and in film in California, Before moving to New York. In 2007 he recieved the Tony Award for best Lighting of a musical for Spring Awakening. In 2008 he recieved the Tony Award for best Lighting design of a play. The in 2010 he recieved his third Tony Award for light deign of a musical. Here is some of his work...

Kevin Adams contributed a lot to the deign world as he as made so many musicals and plays a much better show with his creative and thoughtful ideas.
