Solar Lamp On a Pole, Under a Bowl

In search of a solar lamp for our park place, I found no lamp suitable for a pole, neither cheap nor expensive. All I found were solar lamps for wall mount, the best ones approx 100$.

The best lamp I found, suited for wall mount, was conforming IP44. Obviously, this is not sufficient: it will be continuously exposed to harsh weather conditions (sun, rain, snow, frost, hail) during long periods (possibly days). Very short examination showed that rain can accumulate into the border of the solar panel's frame, and water will eventually seep into the panel. Also, continuous alternation of sun and rain/ice will lead the plastic case to become brittle and surely to eventually crack. I'm not an expert in this area, but I think it needed to get turned from IP44 to IP44W...

Then, I saw a very big plastic salad bowl, that would perfectly fit as a protective cap above the lamp. All this (plus the fact that my mum was urging me to improve the path visibility at night) was more than reason enough to start a new DIY project, so I decided to buy the lamp, the bowl, and a galvanized pole.

Step 1: The Lamp

This lamp is the best one I found, and was approx 100$. Made for wall mount, it features:

• LED panel, 80 LEDs, totaling 6W
• PIR and sunlight detector, to detect beings at night
• Solar panel, with a surface largely surpassing these ridiculously small solar garden lights
• IP44 plastic case
• Three potentiometers to set: Night light threshold, lighting intensity, and lighting duration

Or simply use a clear glass bowl. Could even have the panel protected under it. For a little more oomph, a small mirror or two could reflect the sunlight on the panels in poorer lighting conditions.

Any reason you used a colored bowl instead of a white one?

[laxap]

They had only this color on the shelf.

What lamp did you buy and from what supplier?

[laxap]

Model "Liverpool" (probably made in China), from Ranex (Germany).

IDF supposedly uses solar lights like these along their border fences to be able to see people trying to cross illegally.

He he .. that could be SO easily trolled with an IR-laser. Done that with similar lamps on driveways to houses when I was bored once.

Not sure if they're motion triggered or if they're turned on all night. Haven't been there myself to witness it -my dad was there and was the one who told me.

they also use bulldozers to kill innocent american protestors.

And fellow Norwegian UN peace-keepers in uniform.

And of course, they decided to use flecette ammunition -forbidden by the Geneva convention.

But hey -the tank commander was fined $100. Good to know that us sub-humans are worth $100.

Well, the goal of my lamp was not to intimidate potential intruders, but simply to improve visibility and help my mother and others to avoid breaking a leg ...

Maybe I should add a casing to make it look more friendly.

nice idea.... how much generate the power and solar weight. its sastain the strom... etc..and natural efact ....

[ellislake]

ive been wanting to make this instructable for ages. i havnt read it but i can see its the same idea as what i wanted to do. i just have not had the time to make the instructable for it. well done it is an excellant job m8. that clear piece of plastic material is that uv stable otherwise in 2 years that will go faded and yellowish and will block out alot of the suns rays ?

[Dream Dragon]

Nice job, and well documented instructable, I don't know if I'd want to make it more "friendly" or not sometimes attracting attention and comment is a good thing.

I want one, but I think I would use aluminum instead of a salad bowl.
This is going to sit in the sun, or it wouldn't work. Wouldn't that cause photo degrading of the plastic?

[laxap]

Maybe.. I'll report it in some years.

Very cool!
