    No much to them, LEDs, rechargeable batteries sufficient to run the LEDs to some desired length of time, and what ever features you'd like to add. What's confusing you?

    Thanks for replyn Lynx....I actually want to design rechargeable LED Lanterns for commercial purposes. I have my own electrical business and I want to design something which is very cutting edge and very competitive in the market. Thats why I am looking for some detailed information.

    I think you'll find any information already existing to be either already patented, or classed as 'prior art' and therefore unpatentable, so not much use for a commercial project of your own.


    Why do you specify 'lantern' btw, are you looking for a wide angle beam, 360° spread, what exactly? I have several LED lanterns modeled after paraffin storm lanterns, they are simply LED arrays pointing at a conical reflector, to give a 360° spread. I also have several LED torches (I spend a lot of time outdoors), and have LED torches that use lenses to focus a beam so it's not much bigger than a person at 50metres, and can be defocussed to quite a wide angle, depending on what is required. Many of my LED torches have circuitry to control their power, so one push of the switch gives 100%, and then it's stepped down in increments if the button is either held down, or pressed again in quick succession, and some have flashing modes, to use as a beacon, or blink 'SOS' in morse. TBH, I don't see what you can offer at the moment, focus, select power, and strobe modes are all available, as are built in, or exchangeable colour filters. I've got many and various mounting options for my torches, from bespoke head torches, to holsters, handlebar mounts, to a rotating design that can slide and sit atop a shoulder strap of a rucksack, pointing forward, which is great for hands free work in conjunction with a head torch. Basically I'm all lit up, what do you think will get me to part with more money (and that isn't too hard, I am a torch geek)?

    You are right. What I meant by Lantern is something with a wide angle beam, 360 degree to be precise. By commercial purpose I didnt mean that I am going to launch it in the market. I am actually planning to assemble the product for my existing customers as I am already in electrical business and anyways patented or not patented doesnt matter much in this place especially when the market is flooded with low quality Chinese products. Basically I want some advice on how I can assemble a high quality LED Lantern so that I can make it available to my clients at much lower price as well as the quality of the product should be excellent as this is not going to be profit making project for me but rather something aimed at gaining more credibility among my clients.

    Why not employ a local electronic engineering student to do the design for you if you don't have the skills (presumably you are able to source the parts, etc). It sounds pretty straightforward. They might even be able to do it as a project for their course so they get marks and money: win!
