Their are loads of different types about including really diddy ones only a few millimeters square. The reason why I suggest it is that if you use a 20ma led and use a 20ma regulator then regardless of the voltage input the current will remain the same. (upto the limit of the regulator) Example being that with engine off 12v engine on 14.5 the light intensity will not change but wit a resistor it will. I've done alot of work with led's so I'll post some info when make another set. Farnell components do lot's of current regulators. On a trike I built 3 years ago I put in two high power leds for stop/tail lights. At full power (1,400ma each) it was so bright that following vehicles thought a space ship was landing  Like close encounters! Passed and sva when on half power for brakes lights and only the size of a twenty pence coin!  |

I like your suggestion. If I had a 20mA regulator it would make the circuit layout so much simpler and removes the need for resistors and running LEDs in series. I shall do some research.
Cheers

More LED lights...... This time I was asked to make some small indicators to fit inside the rear light housing of a 66 Mustang to show amber through the red lens.  Homemade custom LED lights  Homemade custom LED lights |

Thanks.  The next project is to make a full LED board for the above light housing to include tail, stop and indicator. Similar to what I made for my 68 Mustang, but without any fancy sequential flashing. |

Just to derail this thread for a moment, we have just returned from a good weekend at the Nostalgia Nats at Shakey, it struck me over the weekend that it is pretty antisocial ( and unnecessarily expensive) to be running a generator at two in the morning just to have light to drink by. We used to light the awning with a couple of five foot tubes but more recently have taken to using a single 28W fluorescent work lamp which is fine. We have a fair bit of surplus 12V capability in the new truck and can recharge at any time. Is it possible to use a LED type set up and get similar results ? possibly a small retail market for a successful unit. Weather proof would be a bonus but not critical, a means to hang it up and a long lead to plug it into the truck/trailer would be good. Anyone fancy a go at it ? we would be more than happy to test it, trial it and market any unit that worked. Failure in my ability to comprehend any of the techno-nonsense behind these things leads me to conclude that this project is far better outsourced.

you can allready get an led recharghable /battery work/inspection light that lasts for hours i,ve got one back over at my old place that the nephew got from somewhere i,ll look at the details next time i,m over p.s my nephew is a proffesional electrical technical wizard so i,ll try and pick his brains too depends what ,,,mood,, he,s in these techy type,s are highly strung  |

It is possible to get pretty good lighting from and led lamp at low wattage. I vaguely remember discussing doing something for you just before my health went down the tubes.

Hey professor B, we spoke about these things at Basingstoke a while back, we took your advise and sourced some 16 diode units to use as ceiling lights in the truck and they are great, hence wondering about the canopy lighting. I have a note hereabouts mentioning "Luxon star arrays" (sp) but that may have been from when I was considering building an intergalactic space cruiser, any thoughts ?

Led tech is moving at a pace similar to computer tech so always new stuff around on a monthly basis. Luxeon stars are good but there are alternatives. Will get back to you by tomorrow night with some options. |
