Once more an excellent video, thanks a lot. One thing I can comment on this kind of flood light is: Over time I have seen several of the ones I've purchased so far (30 Watts, 50 Watts), fail because of a very poor design of the back plate that acts as a heatsink for the LED chip. The way I have solved it has been to re-work the flood light installing inside a 4mm thick aluminum plate on the surface where the LED goes attached, that covers most of the inside of the available surface (100mm x 90mm or so) so the LED now rests over a very wide and thick plate that helps conduct heat more efficiently to the outside of the light assembly. This plate is attached to the inside of the floodlight with four nuts and bolts and also with a sufficient quantity of heatsink conductive paste. Then after the plate has been installed, new holes are drilled and tapped and the LED chip is installed once more in the same position. Then, if needed, the front aluminum reflector plate is re-worked to accomodate the new position of the LED chip (more up-front). This has demonstrated to solve the problem of life span for sure. Another modification I have made has been to install 70 x 70 mm COB LED chips, that give a lot more light than the original LED chip for the same Watts and dissipate heat much more efficiently. This also means that you need to mod the front aluminum plate for the wider aperture (area) of the LED chip. The result is impressive, I have made some comparisons with a luxmeter and you get 40% more light for the same floodlight with the same LED driver. Thank you for all the great videos and explanations.

Wow - you've got some serious manual dexterity going on there. I never would have thought of holding the wires with two fingers and feeding the solder in with two others on the same hand. I'll have to practice that.

I have short fingers, and I cannot do it that way. However I have soldered for a,long time, and this is the same concept, but exactly opposite from how he's doing it. I use thumb and pinky supported ring finger to hold my wires, and my middle and pointer to feed solder. lol I tried to teach my friend this but she too has her own way. She melts the solder to her tip, then uses the end if the wire to wick it up

I knew I had watched you use a double layer of heat shrink some place or another. I am always picking something useful from your videos, this I put to work using MULTI layers of the stuff to build a plug for my laptop when the plug failed, as they seemed to do from time to time. This one failed right where it went into the plug, so as a sort of experiment, I cut away the entire cover from the plug and found that this particular model of DELL had 3 wires that ran to the steel plug, I figured out which wire went where and soldered them up, then began with the smallest heat shrink I could get over the plug, and went on with the next size, then the next, and so forth till I had a nice, thick solid plug lead that extended about 3.5 inches from the end of the plug. This has been working now for a few months without fail! I love it, it is more solid then the crap that came from DELL with the laptop, I was surprised that when I had cut off the plastic overlay, one wire was simply held against the plug barrel by the pressure of the plastic cover, now it is soldered nicely against the barrel and gives me great contact. I went this way since I had already been through three blasted power supplies for this laptop, the one that worked the best was a cheap china crap type that I soldered on the end from the DELL supply that went to shit about six weeks after the warrantee went off on the laptop. Thanks a million for these videos, I can't count the number of things you have taught me since I found your site, I now solder about 200% better then I did before watching your video's.

6:23 In the U.S., the Ronson blowtorch company makes a reasonably cheap butane torch that comes with a miniature catalytic heater attachment. It blows out quite hot gas with no real flame. It's proven to be pretty excellent for shrinking heat-shrink, without the burning and soot that I used to get from using lighters.

There are another couple of advantages of doing this. If you look at the small print of some of the specs for the LEDs then often the 100,000+ hour life is reduced to as little as 5000 if you are running at 100%. There are great gains in life to be gained from dropping down to 80% IE a factor of 10 or more. Reducing from 80% to 40% does not get another factor of 10 increase but it will probably double the life again. I've not checked for myself but I also believe that in the blue into phosphor type "white" LED's produce less actinic light at 80% capacity so 40% should be better for that also. I tend to run mine at about 70% (3W types run at a fraction over 2W).

I agree on the 1 spot for thermal paste, it works perfectly every time but there are some "experts" that claim you have to do it a certain way and spread it to this thickness and blah blah and it really makes me wonder how they just don't get it, 1 spot in the centre covers the centre and when you press evenly, it comes out the side, there is no room for gaps or air as the paste has pushed all out before itself.

Wouldn't the hot melt glue liquefy again when the case heats up? I'd probably use a thermal tape to hold the driver on the casing on the metal side of it. It would also help in dissipating the heat the driver is producing.

I also only use lead based solder. Its also lees prone to whiskering. Which is why lead free solder is actually illegal in some applications. Medical devices in hospitals and in aerospace its not allowed to use it. A single blob of thermal compound is also the way to do it with CPUs. Because some are concave, the others are convex. They are NEVER completely plane, and you prevent airpockets just like you mentioned.

For the cost of two pieces of standard black heat shrink, have you ever thought of using dual wall heat shrink instead? Or is it negligible in cost because you use cheaper heat shrink to begin with? I only use 3M FP-301, so it costs a bit less for me to go dual wall on such applications.

Is it a 10W LED? Some are configured for about 9V at 1A (3 series by 3 parallel) and others for 27V at 350mA (all in series). Using the wrong LED will cause the drivers to pulse because they detect their output being pulled down to a lower voltage than normal.

I bought 5 100w LED driverless chips like this one. I put them in series and used a simple mains (120v) rectifier, I also added a 10w 10ohm resistor in series. I get a voltage drop of approximately 23-24 volts across them and 0.33 amps of current even though they are rated for 30-36v and 3 amps. After running them for 10 minutes I measured a max temp of approximately 60 deg C on the chip face (heat sinked). I realize I am not getting anywhere near their capable capacity but they are still extremely bright and I believe it is better because I should not need a driver at 1/9th of their rated ampacity. I am going to mount them inside of a scrap aluminum outdoor wall mount I have and properly ground it. My concern at this point would be mostly if one chip were to short out the rest of the chip would take on the higher voltage. I've never seen this done before.. I guess because its mains voltage, but it seems like itll work well
@bigclivedotcom
@bigclivedotcom 6 жыл бұрын
The LEDs you have a the plain non-driverless type by the sound of it. You've created a simple resistive dropper series string of LEDs with effectively 10 sets of 50 LED chips in series. The low current means they should last a long time. If one or two LEDs fail short circuit the current may go up and the resistor will get a bit hotter. Biggest issue may be the high mains voltage between the LEDs and the grounded heatsink. But it's certainly worth a try. With these simple circuits you will see a significant intensity variation with mains voltage fluctuations.

bigclivedotcom thanks for replying. I hadnt thought of the mains fluctuation. I suppose i could try throwing in an inductor and cap to smooth it out or a metal oxide varistor. Ill see if its an issue. I checked continuity between the chips -/+ and theres no continuity to its mounting surface. I plan to just ground the aluminum housing. By the way, my wife and I are big fans of your videos (her mostly because she likes the sound of your voice lol)

Asbjørn Mikkelsen The 10W LEDs are available either with all the LEDs in series (about 27V) or in a 3x3 parallel series array (about 9V). The 20W and upwards all seem to use parallel strings of 10 LEDs, so their voltage tends to be predictable at around 30V. It's hard to tell if a light you order is going to be rated at 20W or not until you have it and test it.

The 50w light came with a 70w led chip, the driver label says 50w but the unit only draws 30w of power. The 30w light had a 50w led chip installed, the driver was glued label down so i could not see the writing and idin't want to have to re-glue it so i didnt pop it up.

The size of the heatsink varies according to the power of the LED. If you used a 100W LED in a 30W case it would probably result in the LED overheating and failing. It's better to "upgrade" a 100W light with a lower power driver like a 50W one driving the original 100W LED. That way the LED will run cooler and last much longer.

+jimmytk If you use a 30W driver with a 50W LED you will not get as much light as if you had used a 50W driver, but the LED will run cooler and operate more efficiently, so it would put out a bit more light than an actual 30W LED. the main advantage is that the heat dissipation would be spread across more LEDs, so the LED array should last longer and maintain its intensity longer too.

graet video mate, i've a couple of 50w led floodlights with the led broken, i bought some new led and they work with 36v and 1.5a, i tested mi drivers and they give me 48v and 1.6 to 3 a may that current break the new leds, there is any way to low the current?

Is it possible to increase the current of the driver, even a little? What about increasing an 850mA driver to a 950mA or a 600mA to a 700mA? Simple?

@bigclivedotcom

Yes. you can use a lower power driver. The combined forward voltage of the 20-100W LEDs is similar, but the current is different. with a 100W LED on a 50W supply the LED would be run at half current and give out just over half the light.

+Mod Mike The 100W LED array with a 50W driver will theoretical produce more light than if you had used a 50W LED as the 100W array is being driven at half its rating and will be more efficient. Under-running LEDs gives greater efficiency, lower degradation over time and higher lifespan.

You can't use a higher powered driver than the case is rated to dissipate the heat for. You can use a higher powered LED to spread the dissipation from the driver though. So if you have a 20W rated case you can use a 20W driver, but either a 20, 30, 50 or 100W LED.

No. the case would not be able to dissipate that much heat and the LED and driver could be damaged. You can use a 100W LED in a 20W case if you use a 20W driver.

Too expensive. Some of these things go for £80 in the UK but £15 from eBay. The rest speaks for itself. If you can make me a 100W 850nm Infrared LED floodlight like this that will connect to 12v DC power pack (i.e. 28000mah Aukey) for £20 then I will buy them from you. If you can't then you're the reason why I buy from eBay!

Unless you're electrically competent I would always buy from a reputable local dealer, yeah it might cost you more but dodgy electrics are responsible for a lot of fires, 767 in the years 2012/13 in the UK and that was just lighting, in total there was 20,403 fires and 2,469 injuries, 46 deaths electrical related, you've got to think how much yours and your family life is worth.

Where did you get the statistic about 46 electrically related deaths in the UK? Are many of them attributed to smoke inhalation in fires believed to be of electrical origin? With the new industry of domestic installers being crash trained in two days with no proper mentored training it wouldn't surprise me if the number of electrical fires increases due to the Dunning Kruger effect.

Could I use the original 30w driver (if it's still good) with a 50w led? And have the proper brightness ? Thanks for sharing your vids... All the best to ya!

@bigclivedotcom 9 жыл бұрын
+jimmytk Yes, I'd actually not recommend using a 50W driver in a casing designed for 30W use as it may not dissipate the heat well enough and result in early failure of the LED. If anything you might consider fitting a 20W driver, as that will reduce the case heat and will still run 30, 50 and 100W LEDs, but run them at a lower level than they are intended, so they will generally last longer.

Further to my earlier comment, FYI, I have just received a 30W Lamp from the same supplier, today. On investigation, NO EARTH despite a 3-core cable ( foot long only, as usual) . Not a big deal to fix - but a Pain - would rather have had lamp without cable so that I could install a longer cable whilst it's been opened. The Gland was plastered with hard white sealant, why? It is a great pity that the marketplace is heading this way - unless this was OLD & dated stock ?? benefit of doubt but Life doesn't get a second chance when things go wrong.
