This is one of the smallest proper street lights available. It's made by a British company called ASD and uses a conventional LED panel and a programmable driver.
After the video I was able to reprogram the driver to run the LEDs at just 10W. It's handy being able to read the driver settings of one light and then clone them to another. Ideal for where you are replacing a failed driver, since the faulty one will often still be readable due to its NFC circuitry being powered by your phone's coil.
The Tridonic app seems to work better than the others I've tried for different brands of driver. It still has some quirks, but was very usable.
The mode option was for extra sensor functionality to detect people or vehicles, and dim the light up and down as needed with duration and dimming speeds fully programmable.
The built in logging of run time and electrical anomalies is quite interesting. It has advantages for the manufacturer for detecting false warranty claims where the light has been exposed to unusually high voltage due to miswiring or a lost neutral.
If you work on one of these lights, be aware that the latching system is not released from the top as it may initially appear. It is released from the underside at the pole entrance point. Don't jam a screwdriver under the top and try to lever it open with force.
Note that the wires on the LED panel are a one-way trip. They cannot be removed without cutting them. Trying to release them may actually damage the panel. In normal use the panel would only be changed if it had failed anyway.
I mostly managed to avoid having a rant about the deskilling of labour in the street lighting and traffic signal industry. There's a bizarre UK culture of falsifying electrical skills using one-day slideshow "training" in one of the worst electrical working environments possible - wet and well grounded.
One day I'll probably take a deeper dive into one of the electronic drivers. But they are massively complicated, with microcontrollers and network functionality.
The choice of LEDs is interesting. Quite well engineered and tested under real-life conditions during manufacture.
If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:- www.bigclive.com/coffee.htm
This also keeps the channel independent of RU-vid's algorithm quirks, allowing it to be a bit more dangerous and naughty.

Those lenses are from Ledil, a Finnish company which makes all kinds of LED optics. I've used a few of them for creating my own little LED spotlights, they have really cool zoomable lenses for spots as well. I'm guessing this is actually a catalog part from them. edit: found the part number: C15021_STRADA-2X2 not really useful information just wanted to see if I could

Perfect timing. I just got 3 150W rated 140 lm/W 21,000 lm LED street light modules at my local electronics recycling store for $10 each. None of them worked, but I figured I could get them working. Took one apart and found that if I squeeze the sides of the LED driver it starts working. Bad solder joint. After peeling open the aluminum case for the driver and spending a few hours picking away at the potting material to expose the PCB and components, I found multiple cracked solder joints. After reflowing all the THT solder joints and testing, I found that I had a new problem. The heatsink for the MOSFET and FULL BRIDGE RECTIFIER!!! got up to 130°C after just a minute of operation. Everything else stayed relatively cool. The MOSFET and rectifier tested fine and even swapping them out didn't solve the issue. I'm assuming the potting compound was thermally conductive and was required to spread the heat out to the drivers chassis. Since I absolutely magled the chassis while prying it open and I can't easily get thermally conductive potting compound for cheap, I opted to take a different path. I resoldered the MOSFET and rectifier on the bottom of the PCB and drilled and tapped 2 holes in the aluminum chassis of the light in the correct spots. Then I bolted the MOSFET and rectifier with thermal grease directly to the chassis of the light and glued the PCB in place with epoxy putty. Now everything works perfectly and even with the driver compartment closed the hottest component on the PCB is the transformer at 70°C. Did the whole thing 2 more times and now for 30$ I have 3 21,000 high efficiency LEDs for the shop.

Similar setup is used in some Phoenix Contact power supplies, the parameters for the supply can be configured through a mobile app and then downloaded over NFC even with the PSU still in the factory package (there's an 'NFC' indicator etched into the surface of the cardboard so you know where to hold the phone). When the PSU gets powered up it then loads the parameters from the EEPROM

In the brief time it took you to extract all the goodies from the housing, I had disassembled, "fixed," and reassembled my Generic "Amazon Special" NiMH charger. (Mine is an Opus BT-C3100, but being generic I'm sure there's other brands and model numbers for the exact same charger.) Two of the four slots would have wonky current readings without a battery installed; one slot had a dead moth between the springy negative connector and a solder point on the PCB, the other had a bit of hay trapped between the spring and a surface-mount capacitor. What a relief! I was fully prepared to replace it, but it seems there is no need to. So far, it's lasted thrice as long as the charger I bought from the brand that keeps going, and going, and going... 🐰

@jhsevs 18 дней назад

Leds are gread for flashlights and head torches, but their lack of full color rendering makes them really horrible for other tasks where halogen is much better, like for example car headlights. I live in Norway and driving at night in winter means encountering a LOT of wildlife. Modern LED car headlights barely show anything in the red part of the color spectrum, so deer fur which is brown, looks black under most leds. The bluish light from leds also light up the fog, unlike halogen.

Hi Clive , your comment about the four hour qualification reminds me of the North Sea gas conversions in the late sixties, horror stories of cowboy fitters, eating resident’s food, sleeping in their beds and leaving gas fires and cookers in a dangerous condition. History repeats.

@trueriver1950 Месяц назад

I remember the conversion to Natural gas from town gas. I was maybe 7 or 8. My Mum wouldn't leave the workers alone while in the house: at the time I thought that was paranoia; only later when those horror stories reached the press did I appreciate the truth that just because you're paranoid doesn't mark they're not out to rip you off. Having said that, the "operatives" who attended or house were courteous and sorted out our gas cooker, gas fire, quickly and efficiently and made some reasonable attempt to tidy up after themselves (though inevitably not to Mum's high standards). They also replaced, free of charge, a "gas poker" which was effectively a burner that you could poke into a solid fuel fireplace to light the coal or coke. When Dad came home from work he was impressed because it was a better one than our old one. Two memories about the day, first was the way the "operatives" went from door to door checking everyone's gas was turned off. After that, even more impressive was the way they screwed pipes into the mains in the street and flared off the old gas. But when an industry calls its staff "operatives" it represents an attitude that they aren't people who are able to think for themselves, they just operate stuff. As Clive says, with minimal training. In retrospect, the fact that it was all done by private companies at a time when the gas supply industry was publicly owned was maybe the first incursion of subcontracting into our then nationalised utilities that I was personally aware of. This was well before selling off the gas boards would have been politically acceptable...

I REALLY wish they would stop putting full spectrum LEDs into street lamps. I do astrophotography and the amount of light pollution these things create is crazy. The old sodium single wavelength type bulbs were ok because you could just use a filter to block out that specific wavelength. But it's impossible with full spectrum light. It's also so much worse for wildlife. I understand we need LEDs due to lower power consumption and longer life etc, but they need to have a narrowband filter fitted.

@casemodder89 21 день назад

LED'S as such are monochromatic. so all we need to do is put orangey yellow 'amber' LED's in streetlight and everything is back to fine ! white LED's apperently aren't monochromatic because of their phosphor layer on top of the blue/UV chips. but who prefers to be blinded by a dazzling cold white led rather then by a nice sodium yellow ?

I'll have to take a closer look at those street lights I mentioned previously that they installed outside my place. They're pretty bright, I'd guess way more than 20W and they look a lot bigger than this one, but they do have a flip open lid, so it's possible they're related to this one. I didn't get a great look while they were installing them, since it was dark outside and they weren't that close, that said I got the impression that the lid covered the whole width of the light and also the sides and front, which would help with resistance to rain. So perhaps it's not so related to this one after all.

@@NiyaKouya I apologise for this being a single paragraph as I have to use speech-to-text . the spectral density of a white LED is actually not that great. it is referred to as colour rendering index but colour rendering index is not the full story. If we are speaking about an emission source such as a white fluorescent bulb that is very different as it has a high spectral output. This is why the shadows of LED light sources often have lower discernible visible features. There have also been studies indicating that the spectral density of a source such as a sodium vapour lamp during night conditions under bright Illumination that perception of moving subjects and subtle changes around the road are easier to perceive due to the narrow wavelength- but not too narrow- reducing distraction of other foreign elements related to night driving that are not conducive to vision.

Street lights are always switched centrally around here. Either by a single dusk sensor or by a clock with builtin calendar. LED lights are treated the same way as traditional fixtures, they run from the old electrical system. No fancy smart controllers. Cities can get money from the government to buy LED fixtures but that doesn't cover new poles and cables. Individual broken LED lights are replaced with random fixtures that were on hand atr the moment, often HPS ones.

@tncorgi92 Месяц назад

We've got ones that are on photocell, trouble is that we have a large school where they put in their own circuit and some of the lamps are right by the street. So we get the city street lights coming on at dusk, then the ones at the school come on and their brightness makes the city ones shut off. I think they could fix this by changing the orientation of the photocell but these have been up for about a year with no signs of being adjusted.

Thats how they program you to do what they want.

I agree, like so many Chinese "electronics," we have a mental calculation to do, if it says 30 w take off a third, so 20 w thing is that's its not consistent, Same unit same manufacturer but different supplier different outcome. Rule of thumb cheaper is less ( but not always) industrial equipment from China is all over the map, certainly led driver ratings (or am I just unlucky)

Programmable and robust built street light will live longer than factory standard generic lightning products You can reduce the wear of the light by programming the current limit to light the Cree lights, and need a solar light version

@marcoloos9395 Месяц назад

I think the light always lights for a number of seconds after powering? I assume the dusk sensor does not respond within seconds.

@GeraldPost Месяц назад

I've noticed that the dusk sensors detract from the ergonomics of the overall design of modern lights in general. Why such a huge pimple?

@bigclivedotcom Месяц назад

Some use a small sensor. The big ones date back to huge cadmium sulphide cells and heated bimetallic switches.

@TheGreatAtario Месяц назад

It's curious to me how often you have street lights on. Do you have a side line with the local municipality working with these?

@bigclivedotcom Месяц назад

I've done municipal lighting work in the past, but these were bought for exploration on the channel.

@aaronatwood9298 Месяц назад

They should just rely on the dusk sensor and keep the circuitry to a minimum that is highly durable. We obviously know that electrolytics don't like SMPS where they will be subjected to high frequency... I suggest they use a separate can capacitor with jumper leads, like a PSC motor so when it inevitably fails its an eazy swap and away it goes... Makes perfect sense to me. Or find tantalum caps that don't go bang randomly. 😂

The problem with LED streetlights as opposed to other technologies, is the lack of a diffuser. They are so bright and no diffuser means mega glare.

@bigclivedotcom Месяц назад

They use an array of lenses to create an accurate beam pattern on the road.

@rimmersbryggeri Месяц назад

Are there dusk/PIR sensors for the control connector?

@bigclivedotcom Месяц назад

This one can accept dusk or more advanced sensors/receivers. But PIR would need to point downwards.

So much going on with that light. Are these cheaper than HPS? They look expensive.

@bigclivedotcom Месяц назад

Initial cost similar. Ongoing maintenance costs very different, as the HPS costs £10 for a new bulb, whereas the entire LED fixture needs replaced.

Hey Mr Clive, there is a wave of very similar ‘we do too much but nothing well’ mini light & phone chargers being practically given away on Aliexpress right now, I got one for £3, and it’s dodgy af, like the Bluetooth asks for your contacts and location access, I’m wondering if they’re sold at a loss for data mining, seemed like a job for you! The larger ones are called ‘Big G LED Lights’ because they’re shaped like a capital G, the tiny ones as I got are: Multifunction Wireless Charger Pad Stand Speaker RGB TF Night Light 15W Fast Charging Station - and they’re about 16 cm in diameter. Just a thought! I’ll be modding mine, I just wanted the plastic casing really.

@DelticEngine Месяц назад

I didn't hear any ranting, I heard some helpful comments, likely from experience and observation. Nice teardown, Clive, but I admit to feeling disappointed that there wasn't a schematic of any sort, even if it was just how this particular light sensor worked. On the other hand the demo of the android software was very interesting and a great addition to the video. Considering all the features, I can see that there could easily be a very long video (as in practically a livestream) or a series of videos just on this street light or street lighting technology if you were to go into all the details and demonstrate everything... I'm rather keen on illumination and illumination technology so I'd definitely watch such a video or series of videos. It would also be rather fun to have a go at a DIY version and see how many features could be included.

@bigclivedotcom Месяц назад

The driver would have to be a block diagram, as the schematic would be several pages and take a long time to reverse engineer. The dusk sensor will be featured in its own video.
