Making of the most powerful flashlight in the history of the channel / maciej-nowak-962547184 / mn.projects

When I was making the 30W flashlight, I thought there was no point in building a bigger and stronger one. Some time passed and as always, I was hungry for power. In 3 minutes and 50 seconds, of course, the LEDs were connected in series. Mistake in the subtitles

Czy nie warto było dać uszczelki i zaślepki aby zapewnić chociąż chlapoodporność (lub odporność na deszcz?) np oringi na gwintach i połączeniach? mimo wszystko efekt na koniec WOW
@keysejkeysej2 жыл бұрын
Jeśli chodzi o te podbicie napięcia to przy szeregowym połączeniu mniejszy prąd pobierają diody, a przy równoległym dużo większy a więc musiał by dać dużo ogniw dla dużej pojemności ale miejsce jest ograniczone.

That's a series circuit and the forward voltage for XHJP70s is 12.4V so your overall voltage requirement should be more like around 60v. Maybe you could massively increase the light output by just turning up your boost converter?

@xsauce38582 жыл бұрын
So basically this flashlight will last him well over 20 years so long as he replaces the battery cells whenever they surpass 1500 charge cycles? Since under-driving LEDs extend their lifespan by a huge amount (and boost energy efficiency a bit too) as evidenced by the Dubai Lamp bulbs which use 4 times the LED strings but each runs at a quarter the regular voltage (with a voltage correcting mini power supply) and apparently has a lifespan over 10 times more than a regular bulb, so around 250k hours compared to the average 25k hours a normal LED bulb gets. So this flashlight will last longer battery-wise and overall lifespan-wise than if he used half as many LED chips and drove them at full power. Although thinking about it after seeing the product page, it seems that it can be configured on the PCB to run at 5.6V and 2100 mA or 11.2V and 1050 mA. Seems he might be using 5.6V at 2100 mA per cell, so 5.6V times 5 chips is 28 volts or nearly 59 watts. But that is the regular draw current, at 5.6V he can drive them up to 4.8 amps, so he's driving the chips at around 3560 mA each to achieve 100 watts of power draw, which means he's actually sacrificing LED lifespan by overdriving them and its likely the LED chips will burn out around the time the battery cells reach the end of their lifespan. So these chips with a regular lifespan of 50k hours would maybe get 10k hours at this overdrive level, or a little over a year if the flashlight were plugged in and left on without breaks. At likely usage levels those chips will last 4 to 5 years at my best guess, which should coincide with an average of 300 charge cycles of the battery cells per year, pushing the cells past their end-of-life cycle count of 1500. Although so long as he doesn't charge the battery above around 80 to 85 percent or discharge it below around 15 to 20 percent, the battery should then outlast the LED chips. Hopefully he's got variable brightness so those LEDs last longer.
@Avetho2 жыл бұрын
These LEDs come in different versions: 3V, 6V and 12V. I chose 6V, connected them in series. Therefore, the total supply voltage is 30V
@maciejnowakprojects2 жыл бұрын
@@maciejnowakprojects you can drive them at higher voltages than 6v each and get quite a bit more lumens out of these. You can probably safely drive them at 8v each and cap the current at 12 amps... but I would be cautious without thermal regulation and your boost circuit might also overheat. Theoretically that would increase lumens at the led from ~3380 to ~7850.
@ttonAb22 жыл бұрын
If you wired the LEDs in parallel, you could eliminate the need for the boost converter completely 🤷♂️ Voltage across those LEDs in parallel = 6v Voltage across four li-ion cells in series = 12v to 16.8v

Seems he might be using 5.6V at 2100 mA per cell, so 5.6V times 5 chips is 28 volts or nearly 59 watts. But that is the regular draw current, at 5.6V he can drive them up to 4.8 amps, so he's driving the chips at around 3560 mA each to achieve 100 watts of power draw, which means he's actually sacrificing LED lifespan by overdriving them and its likely the LED chips will burn out around the time the battery cells reach the end of their lifespan. So these chips with a regular lifespan of 50k hours would maybe get 10k hours at this overdrive level, or a little over a year if the flashlight were plugged in and left on without breaks. At likely usage levels those chips will last 4 to 5 years at my best guess, which should coincide with an average of 300 charge cycles of the battery cells per year, pushing the cells past their end-of-life cycle count of 1500. Although so long as he doesn't charge the battery above around 80 to 85 percent or discharge it below around 15 to 20 percent, the battery should then outlast the LED chips. Hopefully he's got variable brightness so those LEDs last longer.
These LEDs come in different versions: 3V, 6V and 12V. I chose 6V, connected them in series. Therefore, the total supply voltage is 30V
@@maciejnowakprojects you can drive them at higher voltages than 6v each and get quite a bit more lumens out of these. You can probably safely drive them at 8v each and cap the current at 12 amps... but I would be cautious without thermal regulation and your boost circuit might also overheat. Theoretically that would increase lumens at the led from ~3380 to ~7850.
If you wired the LEDs in parallel, you could eliminate the need for the boost converter completely 🤷♂️ Voltage across those LEDs in parallel = 6v Voltage across four li-ion cells in series = 12v to 16.8v
How much if we can buy?
06:44 can you share circuit diagram please.? i know this circuit for current limited right.??
