Illumination: incorporating a 'flat light source' into a cardboard project

My partners and I are interested in incorporating a 'flat light source' into a cardboard project we are working on. We need the light to switch on and off when the project is opened and closed. ie. a book cover. I wonder if any of your members can tell us if the technology is available and accessible and where we can find the product.

Thank you for your time and attention,


Charmed

Imagine, if you will, a cardboard box approximately 10" (25cm) X 10" and 1/2"(1.3mm) thick. the box has an opening, a door. Inside the door is a light source...a small one indeed. When you open the door the light goes on and when you close the door....the light goes off. Is there a light with that kind of mechanism? I know this might seem too simple and obvious but I don't know where to find such an item. I appreciate your help! If this is not clear, I can email you a crude drawing...Thank you for our help.

I second Rifaa. Very easy to implement.

hey, you can use LDR....
LDR has the property of giving an output of resistance for the given light intensity, you can even use LDR if it suits you...

I must be clearer. I (we) have NO experience with lamps (bulbs and receptacles) but we are creative. Can you gentlemen be more specific? I will try to be. Might there be a flat and/or small, unbreakable, inexpensive light source that could be installed in this box and that would turn on and off with the opening a closing of a 'door'? I know the lamp below is not flat but it is not too bright (I don't think) which is good and it is small, also good. Price is, of course, also an issue.

There are books that, when you open them, they make wonderful sounds.
I wonder if this same technology applies to lights.

Thank you.

OK. what are the things that u have and give me a sketch of what u want to do.
I will look in to it then.
Let me tell u first when u want to light a bulb what u shud have
one is a light source. for card boards I do not recommend any thing tht gives out heat, a white LED should just do, if u want more light u can add more LED's.
second what is your power source, u need to be specific
third what kind of switches that u can get/buy for example , leaf switch, magnetic reed switches or optical sensors.
please give me a detail lay out and I will help you on this.
Cheers

If you have access to an old Laptop or an LCD screen (LCD screen is something used in a computer monitor, where you can see the User Interface, like the one you have on your Laptop or flat screen displays.)

If you can find a non working display, the internal screen can be removed to use as a light source (diffused light, looks really nice) and is absolutely flat (as flat as your flatscreen display).

If you live in Delhi, India. We can build one for you.

hmm! Not a bad Idea.
He can use a typical screen for a roof and you'll have one nice illumination.
you'll need a minimum of 12V DC to power the inverter though.

1. Imagine a box: 8"X10"X1" (Sadly...I only know inches) There is no bottom to this box but there is a top. Imagine this box is "flat" (for shipping) but when you 'buy' it you open the box and close the top so it stands on the open bottom.
2. When you open the 'flat' box, a light goes on. A small, LED bulb is all that is required, an energy source and switch... ALL in the box...so it would have to be quite small and only give off a little light...I am an artist with an idea so...leaf switches, reed switches, etc. are all Greek to me!
3. If what I describe is possible, I need a lot of information! This also has to be relatively inexpensive. I'm hoping if this is possible, the price would drop if done in large numbers.
4. Thank you...I NEVER GIVE UP, either!
