Well, I discovered a few weeks back that I had to give a presentation for college on something related to electronics...unsurprisingly, I decided on something lighting related.
Eventually, after much deliberation and going around in metaphorical circles, decided to do the presentation on electric lighting, past, present and future. Has to last at least ten minutes plus questions, so I thought that seemed a broad enough topic to fill that time.
Basically going to have it split into a few sections:
Incandescent - Carbon filament, cellulose filament, tantalum filament, pressed tungsten, drawn tungsten, and various gas fills, including the newer halogen types. Intro to each section there will obviously be pretty brief, otherwise I'll have everyone bored to tears, and totally confused more likely than not.
Discharge lamps: Early carbon arc, Mercury Vapour (MA), Medium pressure, including the "blended" types, which I only just discovered actually, low pressure I will do later under flourescent. Due to their rarity, and the fact that I haven't really encountered them, the MD and ME lamps won't be covered here.
Sodium vapour, brief intro to the earlier LPS lamps, concentrating though on the more recent SOX types. Same for the SON types, will try not to ramble too much here, as these are my particular favourite. May add a bit about the SLI class as well, but that's entirely down to whether I find I have a few minutes to fill when I'm done...we'll see.
Last (discharge) section will be on flourescents, including CFL and CCFT lamps. This I've more or less got finished already.
Finally, will be a section on semiconductor lighting, (including a demo of a red-orange 1W LS...). Would show a 5W'er as well, but I don't have one, so I'll just have to use numbers!
What I really need, is a source of numbers so that I can plot a graph of efficiency for this lot all in one place! I've found plenty of numbers for the discharge lamps on
www.lamptech.co.uk , but incandescent and CCFT are proving a little harder to track down. Any ideas?
any ideas, and any advice on the presentation in general?
