Sunset light projector teardown
HTML-код
- Опубликовано: 30 апр 2021
- This odd little light was suggested by Stephen Eyles. It's basically a low power floodlight that projects a wash of uneven colour onto a wall or other surface.
The insides are very simple and can be modified if desired with either a coloured LED or custom filter. The adhesive on the lens came off well with isopropanol without damaging the plastic.
The LED driver chip has two numbers on it:- 7611ASH and KL1A23B I think it may be one of those "for manufacturers only" chips. But it's probably similar to a classic Brightpower chip.
To find these lights on eBay use the keywords "LED sunset light".
Price guide £€$10-15. Some are USB powered and some mains powered. The USB ones may have a simple resistor current limiter on the same PCB as the LED.

"That's what they do with all the undesirable LEDs." haha
And here we thought they just chucked them on eBay as "Warm-ish LED"
@@spokehedz that colour is called: HORRIBLE BEIGE lol
not piss yellow?
Thanks for making this teardown. I'm on my way to making my own sunset projector. Made me see whats going on inside it. Good job!
If you’ve made one can you link it’s pictures and videos somewhere. Would be very helpful
With that sunset color it'd be neat to turn it into a gobo with a beach chair umbrella and palm tree silhouette 😁
7:57 "That's just a horrible color! That's what they do with all the undesirable LEDs. It's a strange... beige LED."
Lindybeige feels a disturbance in the Force...
It's remarkable when your genres cross over.
I believe they call that LED color "golden". Which is funny as I suspect the dichroic material is also gold - it's the same color red as you see in stained glass windows, which comes from gold nano particles. Could be another coincidence, of course.
It reminds me of the low pressure sodium lamps that turned cities orange of an evening in the UK. It washed out every other colour. The suburbs were very monochromatic, moody, places.
Thankfully those low pressure sodium lights are being replaced with other, brighter, more suitable technologies that don't make the streets of England look very dark and very orange. :)
In the US they used those in Florida for a different reason. It brought the kids acne out. They claimed it helped get kids in before the streetlights came on so the opposite sex wouldn't see their blemishes.
here they changed the lamppost with LED. everybody hate it. you cant see much on the streets at night anymore.
@@kevindondrea144 Ehhhh, where'd you hear that one? I know there has been discussion in the past of using bright pink lights in areas where teens congregate, as it enhances/highlights skin blemishes and acne etc, but yellow sodium-based light?
Orange is the opposite to Blue.
Thumbnail and title are very attractive. It does look like sunset.
Yes
Now I want a mythical beige LED. It doesn’t shine beige light, it turns what ever it shines onto into shades of beige, as long as it shines on it.
Thanks for the teardown. We have the version with the thin stalk, and honestly, we are quite happy for it for the low price. The dichroic effect when turned off actually looks nice and a bit mysterious from the outside.
Yes, You Are the Lighting Man!! (positive chuckle during video, thx)
Happy Saturday morning to you from Sioux Falls South Dakota!
This beautiful light will let me keep it on hours of hours and i will not be bored.
And that red lense is so attractive.
I actually have small blue light that's always on.
Ah, the classic Twitter dropshipper lamp. Maybe see if you can find some of their other products, like the galaxy light or the infamous purple "suction" vibrator.
yes, I do wish eBay would show listings highest price first to discourage the 1 dollar for the sticker and 10000 dollars for the item in the photo.
When i was using ebay about 2 years ago this wasn't that common but now it's everywhere and it's very annoying
Yeah, it's not a bad feature for say, offering accessories with the main purchase, but it should list the expensive option first or the picture should match the price.
It would be nice if the virtually split all the items in the sellers "multi item listing" so you're only searching the specific size/model/count etc. I love seeing "sample, 1m of tape"....... It was MEANT to be for different sizes, but is now also used for quantity, though they have quantity discounting separately, its a mess. But... they're not going to change it to make less money.
Other websites do it too, I've seen it done on Amazon and AliExpress. Wish there was some kind of regulation, or option to sort results in highest priced product.
Thanks. The one my kid ordered showed up yesterday. Now I don’t have to take hers apart.
Don't have to? Has that really ever stopped any of us?
Such a lovely light colour. Even without the coating it seems like a nice light, on my end at least. And that effect in the coating is so cool!
That was my thought too, for when you want' "golden hour" lighting on demand.
3:45 I worked with a lot of those LED packages back in 2007-2008. The leads in most instances were only attached to the die by a pair of bond wires, with the slug in the center of the package being a thermal via to the mounting substrate. The large copper fill on the top is not really doing anything in terms of heat removal but rather to reduce process wear on the etchant.
Off to look for sticky dichroic films.... 😁
I could see so many possible uses for this, both as-is and modified!
Nice, I literally ordered this 2 weeks ago and now this video comes
At first, I thought that lens was moulded in situ, which would have been weird, but when you peeled the film off, it all becomes clear! - To be honest, it reminded me of the 'Ruby Glass' bull's eye lenses once used on railway crossing gates. For anyone who wasn't around in the 1960s or earlier, it's doubtful you will have ever seen one in use, if at all.
I was half hoping you might put the lens backwards way round and see what happens!
My guy - the intelligent technical breakdown we all want to see
Hi Clive 🙂 just got a yellow and a blue one for my front room so thank you for this video hope you're ok 😊☀️
Always something to learn here and to be inspired by!
Indeed!
One week ago...?

The convex lens adjusts the focus of light in a specific area
I think they were hoping for a Big Clive "Tear Down". It was easy to take apart and the easy remove tape helped avoid needing cut off. :)
I've got one of these now with two LEDs in, an inner (white?) one and a ring of (RGB?) halo LEDs around it, so obviously they're evolving!
It's one of those beige LEDs that were all the rage in the 70's
There weren’t LEDs like that in the 70s.
Beige LEDs in the 70's LOL
:D Good one._
Lindybeige would endorse this light.
I'd like to see what effect it would have with a high quality (high cri) led inside - rainbow joy?
this video is so cool! it gave me lots of ideas on how to convert regular lamps, like i wanted to paint the glass cover of my halogen floor lamp with glass paint but im thinking this film would be much cooler and easier (for me anyways its been shockingly hard to find heat resistant paint i'm so paranoid of the glass exploding while the lamp heats up)
Halogen lamps can be used with dichroic filters, but there will be a lot of heat and low efficiency.
so pretty!
🌈
"Puce yellow" sums it up nicely! Got to buy one just for this reason!! :-D
I was wondering how the ring effect was made! It was that bit of yellow LED that wraps around the film! Thanks for making the vid!
I'd definitely modify some of those to run on low voltage to try in the garden. ☀
why 1 week ago?!
@@johngonzalez3634 patreon
Need one of these on a timer for my new apartment. We get no more sunset colors here on the eastern (boring) side of the mountain range.
what no ioniser:-) nice video
Bear with me... **bears**
Interesting. Looks like that could be modified quite easily for 24V operation or even better constant current.
Man ive been trying the rgb and uv floods! The novostella are my favorites so far. The 15w happy lighting groupable are ok not bit but about 60w output to my eyes.
Oumelike uv with cord switches are ok too
Tell me where to buy the bulk bags of bright leds? I want to build color specific red green blue for a 3 channel color organ 400 watts per channel
I don't think that I have heard BC say "Well, to be honest, that was shite".
Yes, but not so many words...lots of OTHER words! :D
I think he is much more honest than that ;)
I'm pretty sure I have heard those words more than once, but it was almost certainly on BigCliveLive streams, and possibly after consuming particular carbonated beverages.
Great video! Are these types of LEDs dimmable? I’d like to have one of these light up slowly in the morning as a sunrise
So the filter is a dichroic film over an orange gel?
Hi love all your stuff keep it up. Just a quick question did you know David icke is A member of your local lodge. .???
Interesting Urine coloured LED. I wonder if it gets rid of mosquitoes if you put it out in the garden.
Apart from being a pure colour, dichroics reflect, rather than absorb, the light they don't pass, so that they stay much cooler. Maybe not so much relevant for few Watts of LED power, certainly relevant for several hundreds of watts in more substantial lighting.
Strange - I have just 3D printed a small focus able spot light using the lens from a broken flash light. My "spot" is a bit more fuzzy though 🙄
I did not expect the use of film on a plastic lens. I saw these in red and blue on FB and thought maybe they where using recycled lenses from old larger video projectors.
Ah now, I wanted to buy one of these when I saw them advertised on Facebook, but my friend showed me how "advanced" their technique really was and I realised I could make the same thing at home 😂 so using a laser filter and a big lens, you can get a light that changes colour at the edges
Cool lens, bro.
2:32 What was that yellow-flash at the bottom of the board ?
Aliexpress "warm white" LED. :) Got two flashlight retrofit LED bulb from different sellers and both were lemon yellow instead of warm white._
What do you do with the things you take apart? Do you store it all?
Sometimes salvage the good bits or box stuff up.
This looks really pretty
Thanks for the heart Clive
What kind of sorcery brings us a non-flickering Hopi?!!
Just a longer automatic shutter speed due to low light.
New camera or you adjusted the refresh rate to match?
First thing I noticed too.
@@kevindondrea144 Clive hasn't mentioned a new camera so I'm going to go with 'he adjusted it down'. Or alternatively, a software update now controls the shutter speed in a way that avoids the display flicker.
i got a question i opened up 1 of them led tube lights the 1 where 1 side is live 1 side is neutral i pulled out the driver and connected it up again when i check voltage it reads 366volts dc why? and how for a 4foot led tube
It's common to boost the voltage for very long strings of LEDs. Simple current control, since the peak mains voltage can't cause current flow through the LEDs on its own.
Where can I buy just the different color films for the light?
eBay has various dichroic plastic films.
At last, the legendary 'brown' led !!
Bought a garden rgb spot last year. Modded it with an esp8266 and esphome. No i can use it with wifi instead of ir remote :-)
I have one of these on the way to see how it works, then you beat me to it! Haha Curious of they’re all the same. We’ll see
I wish they used those tiny little incandescent lamps (like the ones used in flashlights) in these.
Huh. We had a sunset projector at the planetarium I worked at in high school that used a plastic filter and a gear motor. When you turned it on the gear motor would start running, and the dimmer switch on the console would control the the brightness. It cycled from orange to blue as it progressed.
Andonstar make some pretty decent scopes. Your Aussy counterpart can confirm. About £30 gets you one reasonable for reading those super tiny numbers.
Chip is from silan dot com dot cn, SDH7611ASH Iled = 0.6V/(4*Rcs) * Np/Ns Rcs is resistor from pin 7 to ground, Np/Ns is transformer ratio. Sadly, nicemilf is only on ebay uk. Thanks for the video.
That could form the basis of an NBTV mechanical television with the addition of a suitable Nipkow disk.
Looking forward to the dooby update
So that's where the "Urine Lime" LED's are used.
Clive I know you have the flush led lights…how do these compare? Which is better? If you want good lumens/realizability. Thanks clive.
These are just for low level decoration.
@@bigclivedotcom makes sense. Thanks Clive.
Hi Clive, Great video, you got the light just right,One question and i know it's off topic but when we use a multimeter to test connectivity, can the current mess up the chips, using a gp meter
It's very low current, so shouldn't damage anything.
Similar construction to the hackable spotlight you looked at about a year ago or so.
i have this kind of 1w led with very strange yellow color ...like sodium vapour lamp
that reminds me of the "bug light", fun fact: i bought one of those yellow CFL "bug lights" (with a super discount) without knowing what it is used for (googled it right now), it apparently avoids insects beeing attracted by the light by reducing the wavelengths that attract em, not sure if it works, very dim at the end to be honest... i sincerely tought it was a "love nest light" LOL
Thank you I🥃 X
that the color mixed LOL like
the camera filter.
Hm, I wonder if it would be nicer with an incandescent lamp through that lens? Since LEDs are very narrow in their light spectrum, and that dichroic coating looks like it can do lovely things.
You can buy the film by the roll/meter/whatever.
www.ebay.co.uk/sch/i.html?_from=R40&_nkw=dichroic+film&_sacat=0&_sop=15
It would get too hot and melt the lens and a fire hazard if incandescent was used with the same luminosity. It would look nice though.
the film used, what kind of film?
Dichroic film.
Very cool, with lenz and coating. Plz sir, may i have a schematic and chip id ?
The little LED power supplies are commonly available on eBay at low cost.
@@bigclivedotcom cheerz. I dont have a computer or phone, just a television with utube hard coded (pre-andoid). Thanks anyway. I enjoy you live streams also, new super computer looks good. ;)
What type of lens it is Convex lens?
I'd describe it as a collimating lens.
Can you convert watts to lumens. I notice light bulbs quote lumens with low watts. An old light bulb might say 60w but what would be the equivalent lumens.
It all depends on efficiency,and that can vary between tungsten lamps.
When in doubt, whip it out !
Enlightening...
Cool. Is there a coating on the LED it'self?
No. Just the chip and phosphor.
@@bigclivedotcom Thanks.
Why isn't the HOPI flickering in the beginning?
Low light, slower shutter.
Clive Unrelated Topic: Topic Pro Audio, Converting TRS or XLR to Component(RCA) interface. Easily created?
Complex subject that will depend on whether a signal is balanced and how it's referenced to chassis ground. It may be possibly to connect line level signals directly or via an audio matching/isolating transformer.
@@bigclivedotcom More of an integration. I recently acquired a substantial collection of pro audio equipment and I love the way it sounds. However, all of my existing A/V equipment is consumer grade. I am looking to input said consumer grade equipment into the mixer for easy selection. This is where I'm having an issue finding an answer outputting from RCA and inputting to TRS or XLR.
i bet they sell loads here in Ireland.. we never get any sun. : (
Surprised they used this type of power supply it cant be cheapest light on the market. Odd sticky film but very interesting stuff.
Can you please make a video on HFSSTC
I try and avoid Tesla coil stuff because of the risk they pose to electronic stuff in the vicinity.
Have some dichromic lampshades here that are gold & crumpled for that Nasa space insulator look. Very effective:)
what is the name of this type of lens? (I'm Brazilian, and I didn't understand what kind of lens this is)
Sometimes called a collimating lens or a bullseye lens.
@@bigclivedotcom Thanks man!!
I would be changing that plug for a fused one. 1A fuse 🤣
It works well on 16A circuit but not for 32A circuit used in GB._
Beige LED? Lindybeige starts feverishly searching e-bay.
Ahh that is what they do with all the LEDs that come off the production line urine sample yellow.
Good Morning, Happy Saturday !!
A beige light, send it to Lindybeige.
Whats it to project?
Just a wash of light.
I wonder if that beige LED is a reject caused by LEDs made with a bad batch of phosphors? In that case, it could be leaking UV!
I think the beige yellow color is usually the cheap "warm white" leds they use in plug-in nightlights. It usually doesn't look too bad of a color when it's the only light emitted. It makes it look like a yucky yellow color if you were in an incandescent lit room and turned on the led due to visual color reference.
This light might have worked better if you could screw the lens to change the distance from the light
I wonder what a building wrapped in iridescent plastic would look like...
Lots of dichroic film on eBay for another interesting project.
seems expensive for what you get?
Not really, for the case, driver, LED on PCB and chunky lens.
So the red is not perfectly monochromatic this is why this effect can be achieved. A rainbow with only orange-red spectrum.
I could even do a mini tear down so you can see the workings of it on my channel.
I'm still waiting for you to reverse engineer one of those garden solar stick light circuits! I can't figure out how it's charging lol
If you mean the standard garden solar light, it uses a 2V solar panel to charge a NiMh cell with just a diode in series (in the driver chip). The solar panel is a limited current source and the NiMh cell can be trickle charged continuously.
