What is inside a LED streetlight ?

Faulty LED streetlight. The LED cluster works fine, the electronic driver device is faulty.
So much for the longevity of these LED streetlights. as usual the electronics fails. the LED's are pretty reliable.

[@mrclucker1969]

The LED's are quite reliable nowadays - shame the electronic drivers are not!!

[@UltimateDIY]

Good video. I'm really getting sick an tired of the current wave of low quality products with high prices. They are designed to barely make it past the warranty period.

[@rustymotor]

Nice units, you could save the enclosures for scrap metal, should be worth something. Are you going to open the driver module to see what failed? Might be something simple like a fuse or dry joint around the driver Mosfets or other power delivery components. You also might be able to purchase low voltage LED driver modules suitable for those LED arrays, they switch on the LEDs at a high frequency, Max current to achieve high brightness without frying them. Thanks for showing this video.

i have a number of 2nd hand highbay led lights in the shed, the dies are a series parallel string arrangement which cause strings of leds in each die to fail resulting in reduced output. i sacrificed one die on the electric frying pan and reflowed the leds. i recovered enough to save the other 12 units which are frightfully expensive new. These make great instant light, no starters etc, great for a big backyard! when i look at the compartment that houses the drivers, there is no good ventilation. imagine the heat of the summer sun on that housing all day, then heat from leds all night - no reprieve!

[@MrMacman98]

Great vid Ray! Put together by Sylvania I believe, my opinion on these lights are that they're expensive, glary and yet more E-Scrap for the environment! A B2224 or Roadster would NEVER fail like this, but yet they still keep on replacing them with this junk!

[@RODALCO2007]

+CAL'S ENGINEERING 100% Agreed.

[@MrMacman98]

***** trouble is, they should be testing them all long before they go into commission, I used to know a bloke who installed B2224s in the early 80s, they never had issues with dud ones

[@MrMacman98]

***** wouldn't it be cheaper in the long run though just to leave the original luminaries in service than to replace every single one based on how much power it uses, individual bulbs and small components don't cost that much

[@shanester366]

+CAL'S ENGINEERING where I live in the US they typically leave the old fixtures in untill they burn out then replace them with LED ones. Except the ones on power poles, for some reason those are all still the old style, even the one they just replaced near my house they replaced with a sodium one

[@MrMacman98]

coolbro12389 yeah there's different systems all around the world on spreading the LEDisease. I know our local power company changed all the mercury luminaries over to 8 watt Fluro batons over a period of days. Not as good as the mercury lamps, but better than LED I guess

[@craigybus1]

I've noticed the LED streetlamps they have put up near where I work are always cutting out, and this is in the UK

[@RODALCO2007]

+craigybus1 Probably thermal issues with the drivers, my guess.

[@jdriver2308]

i have the same thing happening on my road

[@mwalton7951]

Excellent Report Thank-you!

[@SeanBZA]

Simplest way to increase ballast life is to put decent surge protection in there, and to use a line reactor to limit spikes. A series 125W mercury ballast would likely make the driver last at least as long as the mercury lamps, though I doubt it will do the multi decade that older mercury lamps are capable of doing.

[@SuperBrainAK]

i love how you say "easy plug and play of components", so why the heck did they not just get new driver boards? any way this is how we get our things! through the carelessness of people! tfs!

[@MatteoMabesolani]

here in italy we are installing a lot of this instead of sodium or mercury lamp but ours does not have a photocell, they are controlled by the fotocell of the central unit, where the meter and the differential switches are.

[@RODALCO2007]

+Matteo Mabesolani (Mabe) Awesome! We have the central metering and photocell set up as well, for motorway lights. Others are controlled by Zellweger ripple signal and others are on a pilot control wire system.

[@Littlewing6was9]

@@RODALCO2007 what's the Zeleweger ripple system? Like radar controlled?

[@DjResR]

It could be possible to get it working again with 400V 470nF or 680nF capacitor dropper and a bridge rectifier in a small terminal box. The case itself is quite robust. Nice salvage.

[@RODALCO2007]

+DjResR I am looking into that with a current limiter on switch on.

[@LakeNipissing]

They design the device for plug in replacement internal parts, with hinged access panels, and the whole thing gets thrown in the bin anyway. Likely all it would take for repair is to upgrade the faulty Philips switching supply.

[@RODALCO2007]

+LakeNipissing True, the streetlight maintenance guys need some additional training here.

[@veil67]

so far for all the LED that is been installed , most of the issues is bad photocell mostly ,many dayburning ,saw only one faulty head ,was restricking all the time

[@andrewkemp15ii57]

LED street lights take longer to blow + there more brighter than MV & HPS lamps?

[@andrewkemp15ii57]

Those must be MK1 streetLED fittings I have the MK2 on my street & none have failed Melbourne is getting the roadLED with is a bigger version of these.

[@andrewkemp15ii57]

Those look like the StreetLED MK1 my street got the MK2 with a removable nema PE cell they wore installed in 2016 & none have failed they are all working fine?

[@JamesEncliffe]

These things are going in all over the place here. Three problems, 1. they are still fitting lamps that are far, far too bright. This was a chance to replace the high-pressure Na floodlights (!) with something more sensible 2. It is much less safe and easy to drive at night because oncoming headlamps can't be distinguished from the white pools of light from the streetlights. 3. They cause more lightpollution because of reflection from foliage and the ground, not helped because of point 1. They need pale amber filters to colour the light. The old low-pressure Na lamps, fitted in proper reflectors, would be far cheaper long-term (there are many here that have been in service for over 30 years and still the same tube!) and cause much less light pollution. Usual case of council decision-making by people with no common sense, just led by the nose about what they read of LED advantages.

[@HDXFH]

Actually same LEDs in TV Backlight

[@powersource7384]

what you recommend LED chips and LED Module Manufacturer and Type for Hot Countries (Desert Area 50c degree in summer) also the top efficiency 135 lumen/watt and long hours 100.000 hours

[@andrewkemp15ii57]

The ones in my street take a different PE cell the same as a roadster?

[@bluefoxtv1566]

I wouldn't judge the longevity of a device on two failed units when there are probably 100's of these still working.

[@RODALCO2007]

+BlueFoxTV True but there already a lot more LED failures happening despite the long life expectancy. The LED's will make the hours, control gear not too sure as it has electronics in it.

[@HDXFH]

I like the design, A Meanwell PSU would be a great upgrade in these, the stock SDamscum ones are crap!!

[@kyoudaiken]

+HDXFH Yes, they are. I am rejecting Scamscum everywhere. When I notice, that somewhing has a Scamscum-Chip, it will be replaced and sorted out. I don't want to have anything from this crappy manufacturer!

[@Coolkeys2009]

+BloodySword Did I miss something Samsung did not make the failed PSU. Next we'll be blaming the Chinese for that throw away junk even though the failed part is from I believe a US owned company.

[@kyoudaiken]

+Coolkeys2009 Also Scamscum LEDs are failing. I had some LEDs from them in my self build lamps and I underrunned them with 80% current of the permanent rating and they died just after warranty. The PSU is from Philips which is a Netherlands company! The PSU probably blow its fuse because of the crappy Scamscum LEDs that always go short when they blow up... Advise: - DO NOT buy anything from Scamscum! - CHECK your appliances for Scamscum-Parts in Tear-Down-Videos!

[@Coolkeys2009]

***** I'm not a huge fan of Samsung myself, but what is the point of slagging them off for making a more reliable product than Philips in this case. With all the advances in science and technology the only things that seem to be happening is the life time/life cycle of items seems to be getting shorter. People should be asking why and pointing the finger in the right directions. Unless you want to replace your washing machine and TV after every 2 months by 2030 LOL.

[@kyoudaiken]

+Coolkeys2009 You vote with your wallet. When Scamscum-Crap does not last long, you avoid this manufacturer. That's the only thing you can do as a customer! My PC is totally Scamscum-free. RAM is from Kingston w. Micron DRAM ECC chips, SSD has Toshiba flash chips (Intel 750 SSD PCIe Addin).

[@ggesdsdsdsd]

Did you find anymore of these?!

[@ickipoo]

Might be a few dollars in scrap aluminium there. Or replace the drivers.

[@ghmusic8116]

Odd fitting... Why"s the photo electric cell facing downwards instead of the normal Mounting on top of the Lighting Fixture? Surely it wouldnt get its full working potential pointing downwards and so close to the Light source Just seems a bit odd?

[@RODALCO2007]

The LED's lightbeam is at a very narrow angle. it doesn't affect the workings. The current lamps we install do have the photocell at the top.

[@HDXFH]

i want one of those LEDs lol

[@andrewlittleboy8532]

Led streetlights should be banned, horrible things.

[@andrewlittleboy8532]

+LED Street Light they're just to bright and intrusive when trying to sleep, shining through windows keeping people awake.

[@martinlu1644]

how to contact you ?

[@matthewgregory8218]

No wonder they last so long

[@kyoudaiken]

There we have the culprit for them to have stopped working: Samsung

[@BoomBoxDeluxe]

So, let's get this right.... one bit pops, and they rip out the whole fitting and put another in?! Seems like a plan to keep _someone_ caught-up in a constant "pay-pay-pay-pay-pay-pay-pay-pay-pay-pay-pay-pay-pay" with no way out! Why does this happen? Something which is working perfectly fine and will continue to do so for years, is ripped out and replaced with UTTER TAT. I hope they kept ahold of the old fittings for a little while, just to see if the new ones worked out..... chances are, they didn't! An instant _"Rip-Out-And-Chuck-Out"_ forms part of the constant "pay-pay-pay-pay-pay" plan! I AIN'T HAVIN' IT!! It just proves that these things WERE NOT rigorously tested..... I'd be ashamed and down right embarrassed to put my name on that tat! I bet the council didn't buy only one unit for testing purposes, just to see how well it worked out...... chances are, they weren't allowed to buy just one unit, again, all part of the constant "pay-pay-pay-pay-pay" strategy! That's what it comes down to at the end of the day...... *STUPID POXY MONEY!!!* Stuff technological advance, stuff good quality, stuff longevity, stuff company reputation, stuff the environment. Stupid *POXXY* money and shareholders. That's all that matters now! NOT HAVING IT! Thanxx for showing, -BoomBoxDeluxe. _25th January 2016, 11.13_

[@HDXFH]

most use samscum drivers!

[@Coolkeys2009]

+HDXFH I would be focussing on the part that's broken wasting the tax payers money. Looks like Samsung did a better job than the other company.

[@simpsonizer]

+Coolkeys2009 Not to mention the old reliable fixtures (sometimes vintage) get scrapped :-/

[@thelightisbrightandtheshad1301]

I wonder how much of our tax payers dollers have gone into this???
