It's been almost a year since I started to "LEDify" my home, with results more or less encouraging, but only an accident made ​​me find the best solution so far.

Step 1: Motivation

How often happened that you or someone in your family, by mistake, to overthrow the desk lamp? If you are like me, this has happened many times...  For this reason, the last time my offspring slammed my desk lamp one more time, with an innocent "UUPS!", I exclaimed Enough!

Warning! CFL bulbs contains a small quantity of mercury and this is a very toxic substance.
If by accident or intentional, you have broken an CFL bulb, it is advised to ventilate the room as good as possible, in order to dissipate the toxic vapours.

I decided that I have to replace the CFL bulb from the desk lamp, with something more shock resistant...

But that could withstand the treatment of a 10 years child and at the same time to make enough light to work at desk in good condition, to be reliable in operation and decently priced? If only a few years ago, there was no a solution to this question, the answer is now clear: a power LED.
<p>Great one, thanks!</p>

Where can you get the replacement LED light ?
Yes, the heat sink is required... without it, the LED will have a very short life span... The heat sink is not required when the power of each LED is very small... let's say 0.25W (like in LED strings)...
<p>hi</p><p>you say about heating problem but i give my another product such this to my friends for long time may be 4 years ago and he was use it in bedroom in room temperature for long time approximate all along nights and he wont told any problem for its performance and yet it work fun and just led chip show a little decrease in brightness that every one cant not be recognized it with his eyes however experts may found it but it work.</p>
<p>Great! It is sturdier than I thought :)</p>
<p>Ah... the lamp shape is great, because of the cover it won't hurt your eyes if you look directly to it. However you have in the same closed enclosure, both the LED which produce a lot of heat and the power supply which is affected by the heat (it contains sensitive electronics). If you only use this bulb for short periods of time (in the fridge) it should be ok. Otherwise you might have an overheating problem.</p>
<p>hi</p><p>excuse me tudurache i want you just to say about my lamp bulb shape because i create it with my own idea!</p>
<p>hi</p><p>how many concession you give me for for my innovation while you see my hand made products for it size and shape in pecent?</p>
<p>I didn't really understand your question... sorry</p>
<p>hey dudes </p><p>i made 1 watt led for my refrigerator i use chines 1 watt driver and one chines 1 watt led (market JBZ) with an old broke corrupted &quot;sleep-light color change&quot; body that have ultra low bright and my new handmade that it produce 90 lumen that enough to bright in classic 12 foot refrigerator just consume 1 watt and work for long time may be 20 year ,can u develop such this for 1000 - 2000 lumen output in just consume less than 15 watt? </p>
Hi,<br><br>It'a a bit too much for such a small body... maybe one or more strings of leds connected in series powered by a capacitive reactance power supply (it won't produce any heat). It will not be isolated from mains power supply but you could do the job...
<p>h..</p><p>yes i found why my comments are empty.....</p><p>i read cree led components and i see if use new cree led X LAMP- XP-L to get more brightness and have more efficacy due to developed chip and newer technology it give 200 lumen per watt in 350 m.A meant that lamp get 600-800 lumen flux</p><p>and may be grow project to have more bright and less consume</p><p>cree in leader in led worldwide another is Phillips and other have play less role in this industrial and they have competition to try new lumen per watt integer and almost ones win the match if in today we see cree is ahead!</p>
Hi,<br><br>Yes, Cree realy makes great products, a bit expensive but worth every penny... In my ligting projects, the overheating is by far the most vrequent cause of failure, but with Cree leds having such a good efficiency, the heat is not a problem.<br><br>Regards
<p>why you try to remove my comments?</p>
Huh??? I guess only the owner of a comment can remove it's own comment... and the admin (instructables employee) if you break the &quot;be nice&quot; policy...<br>And believe me... even if I could to do so, I have better things to do...<br><br>Peace<br>
<p>a fab idea and replacement to CFL's in very cheap price.</p>
<p>interesanta idee! totusi nu se incalzesc prea tare radiatoarele alea mici de chipseturi?...</p>
Cu radiatoarele de chipseturi nu am avut probleme, oricum LED-ul e alimentat la sub 2.5W si la puterea asta temperatura nu trece de 60 grade. Deja de am de mai bine de 2 ani si merg fara probleme. Mai degraba alimentatorul telefonului pare sa fie sensibil la caldura... am niste becuri cu leduri chinezesti de 10W la care mi-au crapat alimentatoarele. Radiatorul desi e de CPU incalzeste si alimentatoarele si asta le cam afecteaza... e vorba de proiectul de aici: http://www.schematics.ro/Projects/LedLighting6.aspx
Is there any diagram of your design for us to uderstand more easily?thank you sir.
<p>Cut the phone end of your mobile charger. Solder the red wire with the + terminal of LED. And respectively the black wire to the - (negative) terminal.</p><p>Connect the phone charger to power socket and enjoy the illumination. </p>
Well... it's not realy a diagram... only the LED and the phone charger... connect &quot;positive&quot; from the LED with the &quot;positive&quot; from the phone charger, and the same with &quot;negative&quot;. No other component is required :)
<p>Bravo tudurache and thank you for sharing.</p>
<p>Thank you for taking the time to make your website available in english.</p>
<p>Hi Great project, I really like the lamp cover you used in the bathroom version. Just curious - did you make that painting/pattern or find it somewhere (if found...where?)?</p><p>Thanks!!!</p>
I'm glad you liked the project.<br>The lamp cover (together with the lamp itself) that I have used was bought from one of the local stores here in Romania (Dedeman: http://dedeman.ro/) but you might find something similar in other places...
<p>As i have 1W LEDs with me, can i connect 3 Leds a charger as parallel line. Pl reply.</p>
It's not recommended because the LEDs could be slightly different in parameters and the current will not be evenly divided between the three LEDs. However if you have to do this, you could connect in series with each LED a 2.2ohm/1W resistor.
Dude, you have got to look into LED drivers, they are really quite cheap, more compact, and safer for the LEDs.
Dude, it's all about recicling... if I can use that I already have, then why spending money for LED drivers?<br>I doubt that those are more compact and safer than a phone charger... I know many dudes that keep them powered for years and none of them caught fire or even broken.<br>And they certainly are more expensive than a regular phone charger. If you already own a phone charger (cost is 0), the LED driver shoud be more expensive by... you count how many times...<br>Mine already works for 3 years and I didn't have any problems so far...
If you already have a phone charger then absolutely use it. But as for the LED drivers being bigger and more expensive, that little circuit on the heatsink in the first picture is the driver I bought. They are definitely smaller, and I got it for about a buck, so around the same price for a low-end phone charger. However, I did not mean to put down your 'ible, in fact I actually love the idea. And made one myself, pictures 2+3. And I use it a lot. So great idea, and great result, but for those of us who don't have a bunch of phone chartered laying around, LED drivers are an idea.
<p>You're right, if you don't already have a spare phone charger instead of buying one, it's better to buy an dedicated LED driver. But almost anyone has some spare phone chargers, and using them saves the money and the environment.</p>
<p>Hi Tudurache</p><p>I love your work and ideas! Recycling from old electronic parts is genius. I have a quick query, do you think it would be possible to power up to 15 Watts worth of LEDs? I have many 14 W 2D lights that have failed drivers in them, I don't know which component within the driver has failed and really want to be able to replace or repair them. Any ideas?? </p>
<p>Good afternoon for all bodies</p><p> It's a nice project I will to make this lamp</p><p> Thank you for all</p>
personally I find the color of the Q5 LED to be much too green without much blue to even it out. But then again I have blue CFLs for the main source of light in my room<br>nice bulbs.
<p>Its an awesome idea to use the cell phone chargers to directly power the LEDs without using wasteful resistors. Can you please advise the best configuration using 1 W LEDs. Do you think that I can directly connect 2 x 1 W LEDs in parallel to a cell phone charger?</p>
<p>1W LEDs requires about 300mA but phone chargers generates usually more than 700mA... so connecting 3 or better 4 * 1W LEDs in parallel should work, but in order to equalize the LEDs characteristics it's recommended to connect in series with each LED a small value resistor... about 0.5 Ohm or 1 Ohm (1W) should be ok.</p>
<p>Not sure about LED's and electronics but was wondering what it would take to have substantial power supply central place in a house and wire all led lights around house. Would love to remove most outlets and replace with USB connectors to power charging and LED based lighting. You are saying something about the maximum output of the power supply burning out the LED if it is over the rated level for the bulb.</p>
<p>It could be done, but you'll still need a constant current source, for each LED bulb, and this could be more expensive than a phone power supply that you probably already have lying around.</p>
<p>Very informative and useful post by you. This can be a very useful to make a cheap but very powerful LED bulbs. There are so many electronics store which offer the best LED bulbs or lights.

<p>u r to good</p>
<p>Thanks my friend :)</p>
<p>This is amazing. I am just wondering, for safety concerns, how hot does the cell phone charger/power source integrated in the bulb get? I would like to upgrade my desk but am a bit afraid of fires/shorts. Thanks!</p>
