Chinese LED street light teardown.
HTML-код
- Опубликовано: 1 окт 2024
- This is a rather cute little 12W LED street light I got from a Chinese supplier called Banggood. It's designed to run on a 220V supply (180 to 255V) and is designed to mount onto a pipe about 42mm diameter. (1.5"?).
This unit was very typical of Chinese LED lights in that it had a stripped and tinned earth wire in the short pre-installed flex, but the earth wire was not connected internally and was actually cut flush with the flex inside.
The unit has a rather neat printed glass front with four screw clamps that pull it tightly onto a silicone grommet. The LED panel inside is an aluminium core PCB held onto the inside of the case with six screws with heatsink compound between it and the finned aluminium case. The LEDs themselves also have wet heatsink compound behind them which suggests that they have just been pressed into place and soldered without the use of thermal transfer glue. The power supply is a generic current regulated unit designed for driving between 8 and 12 series wired LEDs. It's mounted in a small aluminium extrusion with end-caps and filled with black potting compound.
The lights are available in cold or warm white, but if you were so inclined you could replace the standard 1W LED "beads" with any colour you wanted.
Apart from the lack of a ground connection this is a very neat and well built light. As an actual street light it could be quite effective for lighting a pathway or side of a house if mounted on suitable angled pipes at a height of about 3-5 metres.
I'd recommend connecting the ground lead internally with a small crimp onto one of the screws holding the PCB to the heatsink.
There's a standard size in tubes that's 42.4mm on the outside and plumbers call it 1 1/4" (I think they started by measure the inside diameter and then the steel got stronger). 1 1/2" is 48.3mm.
Excellent teardown and review of this product... keep it coming clive... thanks alot for your time...
These are probably not used by any decent local authorities in US or Europe as it lacks the beam pattern required.
Love watching your videos Clive, you deserve more views!
i guess they are relying on the tube being earthed?
Daniel Austin - This is an old one.......
I guess I never watch this, the thumbnail looks like a giant USB thumb drive.
Those LEDs normally have a solder land on the back that is soldered to a corresponding pad on the PCB, but effectively soldering it requires reflowing the board. The fact that they used thermal goo suggests that the board was soldered by hand.
Designing a PSU for a narrow range of input potential can make it slightly more efficient and simplifies its design. Such penny pinching is to be expected given that the intended market for this is low budget third world electrification projects, which tend to be in 220V to 240V land.
You do so much promotion for banggood, I hope they pay you something, or at least are giving you free samples.
Yeah, mount them 15 feet up, and they won't do anything! They'll struggle to light the area. I have a vintage American Electric mercury vapor light lighting the area up perfectly! LEDs are only really good for indicator lights.
Clive these videos are great - but quite often you comment on the some "interesting part" of the build - but then never go onto explain what it is thats peaked your interest - See the earth wire part of this video. It would be interesting and useful of you could explain what you've spotted and what impact it has (dangerous Im guessing in most cases?)..
Keep up the good work though!
Very unusual design. street lamps usually are mounted on 48, 60 or 76mm pipe (most common is 60mm) and they need much longer wires (most common is 5m or 10m or without any wiring). That short cable is useless for any installation, usually connection (and fusses) for street lamps are at ground level in lamppost.
Not having ground connected is not so uncommon many "serious" manufacturers in EU (like Schreder) do that but their lamps are CL II and anyway lampposts are grounded.
+Miloš Lazović Schreder is Serious???
Bali Gabor
Schréder is one biggest manufacturer of public lighting product in world, but not what they use in Eastern Europe where Schréder is not made by Minel-Schréder and they are sold as Schréder.
Bright Chinese automobile LED headlamps are a topic I hope you could cover one day. It's a war out there with extremely bright headlights taking over the world and there seems to be no stopping them from getting brighter. I'm referring to the aftermarket lamps promoted all over Ebay and Amazon.
You gotta like a Chinese company that deals with things involving electricity and Li-ion batteries calling itself ''Bang Good''. In his newer videos you can see all the marks on his workbench from all the chineseium that Bang... Good.
@bigclivedotcom can you please tell me the exact brand of the LED Light that you cover in this video? There are so many LED Lights on the said website which is hard to find the product you reviewed here. Thanks in advance.
Looks like way to much for weak light. I just found a 50w 4500 lumen for fraction or ur price.
"45 millimeters?" - "43 millimeters." - "But officer, don't the specs say it's 45 millimeters?" - "Yeah, they do."
Hey Clive question for you-I'm considering buying these to modify to make them rugged portable lights with a built-in battery pack. My question to you is do you think I have to change out the LEDs to work with DC (probably 12v) and do you think there is enough room in that housing to fit a reasonable battery and a transformer?
Ben Winter You could probably use a standard 12V driver for 10W LEDs. It might be easier to make a version based on a larger LED floodlight housing.
Blue spectrum that's not good
Clive. Many thanks for this tear down. I was going to get a couple of these in January for my large car port. Based on your assessment, I think I will. Do you recommend re wiring to use an earth?
Many thanks and Merry Christmas
+Merv Howard I do recommend connecting the earth. Also consider some of the very common LED floodlights that are available. Particularly the ones with PIR sensors if it's just for security and illumination when you walk through the area.
These integrated LED lanterns need to be banned, as when they fail, they cannot be serviced as we have with a LED Corn bulb used in a traditional Lantern head
These are throw away lanterns and councils in the UK are being sold them for the energy savings, but failed to see what happens when they fail
Eric Hawkins ... I guess you didn't watched the video at all. The leds are soldered (which MUST be for reliability) and appear to be not glued, which mean that anybody with an iron can replace any of the leds. The transfo might be glued, but nothing prevent you from prying it out to replace it. This is a chinese model, so I wouln't expect any compagny to install them, even less a city. But let's say they are reliable... The repair cost might be close to the retail value of one, so might be more cost effective to replace them and sell the broken one for scrap...
I install a lot of types of street lamps but i did not try this type of bulbs
Have two of the 24 Watt version of this light installed in my garden. Running on a timer, at least 3-5 hours a day.
After one year of use, still works perfect. No moisture in the armature (mounted on top of a pole so they are not shielded from the environment). Only the powdercoat/paint is fading a little bit, but that is to be expected being exposed to the elements 24/7.
Only the clamps for the glass are bad, but they seem to hold up fine.
Very happy, bought two of them for like 50$ shipped. Seems good quality.
If you look in my videos of street lighting you can see the. Modern day R2L2 street light
I *really* wanted to see it in use before the video ended to see how well it worked :>\
In the Netherlands in my town they already have LED streetlights. bloody bright tough..
I've been tempted a couple of times by these lights, but, at the moment I haven't much use for a streetlight (I'd love to have a traditional SOX lamp or two though, before they're all replaced with LEDs!!), but thinking about the idea of swapping the LEDs, perhaps replacing them with sodium-orange LEDs would be useful as the red-orange spectrum is far easier on the eye at night than the bright white LEDs they're barfing out across the UK...
And yes, I'm rifling through your vids, cos they're interesting!! :D
***** I didn't have any use for a streetlight either, but I don't let small details like that get in the way of buying random things to take to bits.
bigclivedotcom
Can't fault that logic, I've been a habitual dismantler since I was pretty young (it was only in my teens I learned how to put it all back together!!!!), so everything I buy tends to end up in bits at some point!!
+twocvbloke.. funny that everyone loves taking things apart but only a few people can put them back together again ( and i'm not one )
888johnmac
Yes, experience of putting stuff back together comes from extensive sessions of taking stuff apart and trying to remember how it went back together again, often leaving piles of permanently dismantled things someplace... :P
they have no earth becase they dont have earthed plugs in china use the w pin plug if i remember right
+jameshone1000 yeah they use a very similar plug to us here in australia. we have the earth pin though.
clive, can you buy small brackets anywhere to wall mount these light?
+Orbital Tube I'm not sure. It might be something you have to make up specifically for the task.
Cool video. Do you have any particular use planned for the street light?
Nope. I just bought it to take to bits.
nickhill92 So you are dealing with led street lights?
Actually, we are factory making led retrofit kits, which can retrofit almost 90% of existing lights in the US market, say street light, cannopies, shoeboxes, wall packs, flood light and so on. You can keep the good old fixtures as you like, just retrofit only.

Ok
forvard voltage ? current ? please add it to the vid next time
"Banggood"- Perhaps the lights go "bang!".
how is this street light holding on, has any of the leds fail?
santiago vindell I've never actually used it.
Chinese LED street light teardown.
LED sucks
have u ever heard of class II luminaires....
Question driver watt use
About 1W per LED.
Lampu jalan
Odd question here... can these lights be dimmed without modifying them?
+Robert Brouse No. The internal power supplies would try to compensate to put out their rated power. The input circuitry would also not be happy with a dimmed supply.
Thank you I will make a frame for some neutral density filters to reduce the glare if it gets bad.
Normally an outdoor led light is not dimmable. Lights for indoor use can be dimmable
Many thanks for your time and advice
Ser nahi banpa rahi aap ka mobail no. Do
I know it was a year ago but did you see what actual wattage it is. ?
Graham R Dyer I've just left it running for a while and it's reading as 12.2W.
+bigclivedotcom Won't there be no earth in this light because it will be attached to a metal streetlamp which is earthed itself?
TehGlitchs That's not actually good enough. there's a risk that if the ground is dry the lamp post could become live. That's [particularly bad news for dogs wishing to pee against it.
Where do I can get this one ?please ?
It came from www.banggood.com
It would make a good work-shop light on a stand..
bad video. Needed to disassemble 4 us to see details....
did you expect x-ray vision?
kkkk Just full desassembly.
Sena Fernandes which it was
???
Where is the fuse situated ??
Inside the driver usually. So if it fails the potted driver has to be replaced.
Nice job
44mm = scaffold
I hate how they always got to make LED fixtures so futuristic and ugly, why can't they just use a typical HID street lamp designs instead of these?
Btw, LEDS were never mean't for lighting in anyway, they were made for indicators and such things, I see these fixtures around my area and some are already starting to fail to turn on at night.... They should of found another way for HPS, MH, and MV bulbs to be more efficient....
+Adam Correia (Cracked Sponge) Its a heat thing. If they threw a nice roundish housing on there it would reduce the heat dissipation.
Brad Madu but isn't heat bad?
+Adam Correia (Cracked Sponge) Yup. I was trying to say that the open design with the fins is good for getting rid of heat.
Brad Madu oh,okay.
I didn't think that heat wouldn't be a problem with LEDs because they produce little to no heat. But still if you were to modify a street light's design that was mean't for a standard HPS bulb, and were to replace the reflector and socket with the LED board or strips, (with no glass panel ore refactor) that would do damage the the LEDs i'm guessing?
+Adam Correia (Cracked Sponge) those low watt indicator leds produce almost no heat but you'd be surprised with what these can put out. That fixture is 12w with lots of surface area so it will run pretty cool. but a 10W bulb that you might put in your house to replace an incandescent will run about 170F (80C) because they are compact and can't have as much cooling. that's why your get an operating life of up to 100k hours from the street light and 20k from a bulb.
outside LED lighting must have ground wire, also waterproof led driver, waterproof glue or silicon glue, your street lamp seems have not waterproof glue.
Our factory produce outdoor led lighting have ground wire, waterproof glue around lamp, USA Bridgelux 45mil high power LEDs LM-80, normally use Taiwan MeanWell power supply ( UL, TUV, EMC, CE listed ect.) long lifespan
Leiming LED Lighting That's the difference from the cheap Chinese and the quality US versions.
Evilkittyof doom I actually bought a couple of there in higher wattage and I added an earth ground lead and a photocell to them, They seem to work just fine. But I am adventurous like that too AND I know what I am doing when it comes to electricity and electronics.
I'd say you get what you pay for... :-)
where can i buy one ?
btw i just sub to you
