Another work light with weird circuitry (with schematic)

Рет қаралды 130,437

Жыл бұрын

I've looked at a few of these before and they all seem to have some weird circuitry twist. This one initially looked almost identical to the blue Aldi unit, but the circuitry has some weird bits that are actually quite clever.
What's not clever is the current the LEDs are being run at. With a freshly charged battery the current draw was:-
High (2 LEDs lit) 3.8A - 11W
Medium (1 LED lit) 3A - 9W
Low (other LED lit) 1.6A - 4.8W
When the zero-ohm links are removed and replaced with one of the 1 ohm resistors the current drops to:-
Both LEDs lit:- 1.75A - 5.25W
One LED lit:- 1A - 3W
The light output is still very useful, but the light runs much cooler and has a considerably higher run time on a charge. That makes it better suited as a rechargeable light source during these turbulent times.

My friend in Kyiv decided to construct a makeshift home light for the periods of power outage (they take place daily, often several times a day). He's got almost no spare parts or modules on hand, but at least he can salvage something from his earlier projects, and between the blackouts he can use his soldering iron. I know a couple of cheap rechargeable lights from a dollar store could save him (especially if they take 18650 cells and allow for replacing them), but when everyone in a big city faces this situation, they certainly don't have enough on the shelves.

I've bought a couple of these types of lights using removable 18650 batteries. I use 3400mAh 18650B in them. They are superb for ice fishing at night. I was worried about the effect of cold on the batteries, but they last so long, and I think the light heats up the cells, so it isn't as much of an issue as I had feared. They don't keep you as warm as an old Coleman fuel lantern, but you don't need to carry a heavy glass lantern, and stinky fuel.

Looks like a decent portable light, and I agree that the resistor values should be altered to give better battery runtime. Even if you don't consider the heat dissipation, pulling 3.8A from a 2P Li-Ion battery pack is not going to help it in terms of battery life (just over 1 hour?) and battery longevity (will lose its capacity faster).

I got one like that a few years ago on eBay but it has a single round COB LED and a flashlight at one end. First push gave you the flashlight, second was the front LED (very bright) and third gave an alternating red/blue warning on the front LED display - very nice. I put in a pair of 5000mAH 18650 cells (in parallel!) - works very well. Everything else is virtually the same except the 'test' button is not there - the battery test LEDs come on with the main LED.

@RexxSchneider Жыл бұрын

It's worth remembering that as LEDs get hotter, their conversion efficiency of current to light decreases. So much so, that at some point they may actually output less light as the current increases. Below that point the light output is a relatively linear function of current, so reducing the current through the LEDs by substituting larger resistors is unlikely to reduce efficiency and may possibly improve it. Given the penchant for Chinese manufacturers to drive all the components as hard as they can get away with, that sort of mod makes a lot of sense.

@kenaston4220 Жыл бұрын

Thats a very interesting point. my one starts off bright and then dims down. If I switch it off and back on, it comes back bright. I wonder if I should back off the current a bit and have a more stable output?

@RexxSchneider Жыл бұрын

@@kenaston4220 If it's dimming over a relatively short period (a minute or less), then it's probably a thermal effect, rather than the battery voltage dropping, so there are efficiency gains to be made by reducing the current and/or putting a better heatsink on the LEDs. Perhaps test the theory by blowing cold air from a fan over it?

The resistor network is not to "stop Apple phones trying to suck as much current as possible". It is actually to _allow_ them to charge using higher current than they would otherwise. If you plug a USB-compliant device (including an Apple device) into a port whose data lines are not connected to anything, it is not allowed to draw more than 0.5A according to the spec. These resistors are configured to tell Apple devices that this charger is capable of supplying 1A of current, so it's OK for them to pull that much. However, I'm not sure why they didn't just go with the more standard "dedicated charging port" indicator of just shorting the data lines together, though, as that also works even with non-Apple devices, and AFAIK Apple devices understand it just fine too (since it's part of the USB BCP spec)..

Relying on the protection board in a battery pack to limit the charging voltage is a very bad thing to do. Protection circuits are generally designed to allow the maximum voltage that won't actually result in rapid destruction (fire!) of the cells. It is expected that they will allow the main charge controller to reach its maximum setpoint without cutting off charging. That means that the protection circuit probably won't do any good in this case and the battery will be overcharged. It takes surprisingly few overcharge cycles of surprisingly little excessive voltage to significantly shorten the lifetime of the battery. Undercharging will result in greater life, both in terms of number of cycles and total energy deliverable over the lifetime of the battery.

1k and 100k likely the standard reel on the PNP machine, though I will bet they also will drop any value from 560R to 2k2 in the one position, and 82k to 220k in the other, depending on what is on the shelf when the reel ran out, and what was on sale that day in the market when they went looking. Yes putting in higher value resistors for the LED will help, probably best done using actual 2W wire ended resistors on short leads, tucked up in the spare space in the unit. Making them 2R2 and 3R3 would probably not drop light output much, as the lower current will drop the LED into a more efficient part of the curve, so 50% longer battery life and likely only a 20% drop in light output

"power outages around the world" are you perhaps mentioning South Africa as well. Wr currently have scheduled power outages. Wr even have different stages. If our power capacity is good then it's stage 0 . And we can get up to stage 8. Basically the higher the stage the longer and more power outages wr get in a day at a scheduled time. Right now we are at stage 4 and in the town I'm in at the moment (each towns or city's scheduled time is different) that means we have three scheduled power outages that last for two hours each . We call this loaf shedding because we're shedding the load of different towns at different times. But as it is our power infrastructure is pretty fucked.

So the strobing is easy to notice, at least for me, while walking them and passing by objects. (although, I think that was due to the one cell being crappy, as the pair I'm using now have lasted a couple weeks of ~15min/night on Low w/o the light cutting out! 🤘) 🤔 Maybe I should wire a switch into mine, inbetween the two cobs, so that the switch gives me independent control and then I can just run _one_ cob @ High...

I have a very similar light that is a nebo tango light. It has the two different leds that can operate independently. Or together on turbo mode. But it is dimmable for both legs independently. With small light on its lowest setting which is 25 lumens it says it will last 35hours. Battery doesn't last real long in turbo mode with a 1000lumens for only 2minutes. It several other settings that last a lot longer. Anyhow when your light is on hold the power button and maybe it will be dimmable. Pretty neat feature. This one says HL18B. I have had this one for two or three years and it has been pretty handy and reliable.

Since it's a microcontroller based design, they could have easily added an even lower power mode using PWM, and also increased the max power by eliminating the power resistors and just using PWM in the current low power mode. So the modes would be: 0. Off (unchanged). 1. Both fully on (brighter). 2. LED1 fully on (unchanged). 3. LED2 at 50% PWM (unchanged brightness). 4. LED1 at 5% PWM (new long lasting) .

I'm a quality control engineer in a German company and i noticed lately that some RCBO typs in combination with Socapex (6 channels) a remaining voltage of 20~30 volts. And it's not a capacitive effect because it does not change if i move wires away from each other. Do you have any experience from the entertainment industry (Socapex) standard. About the matter? I know it's ok as long as it's below 50v. Thank in advance for reading and commenting or maybe video about the subject

@bigclivedotcom Жыл бұрын

In socapex you have six circuits in very close vicinity in a multicore. There are capacitive coupling effects between the cores when measured with a high impedance multimeter. Testing with a proper electrical tester would add enough load to shunt the effect. Dimmers also have high leakage when off due to the snubber networks.
