evaluation

This term the year 9 design futures students have explored and researched light. We were to design and make a small working desk lamp using LED technology. It was to be free standing and stable.

FUNCTION:
Does the arterfact do what it was designed to do? Yes, my LED desk lamp is free standing and stable and throws off light onto the desk.

Does it perform effectively and efficiently? Yes, it turns on and off efficiently and throws off a very bright light onto the desk allowing study/work to be done.

What improvements, if any, can be made to improve the artefacts function? There was only one improvement that i think should have been made.  The curve of the aluminum should have been a little greater so that the arm with the LED light is at a higher angle so the light gets thrown out further onto the desk.

AESTHETICS:


I am very happy with the aesthetics of my LED lamp. My lamp is a suitable shape for 2012 because i find it very modern. The shape of my lamp balances well with the block of Jarrah wood, it is not unstable as the angles of the shape match up perfectly. Overall the visual aspect of my lamp is very attractive and i would even consider buying a lamp like this one if it was to be sold in the shops.

ERGONOMICS: 


My LED lamp is very convenient being small and compact, light weight, and very bright. It is very useful when it comes to study, homework or reading as it will light up your page allowing you to see clearly. There is also no safety issue when it comes to electrical faults, light faults or unsteadiness as it has been very carefully wired and very carefully been adjusted so that the lamp is as steady as possible.

ECONOMICS:


This lamp was very cheap to build making it very cost effective although it took a lot of time to make. Prices are as listed:

• Aluminum- $2.40
• Jarrah Base- $2.40
• heat shrink- 15c
• LED strip- $5.85
• plastic- 45c
• cord- $2.80

In total my lamp cost around $14.05
