LED FOR SURGICAL GLASSES

Long story short: the host looks cheap and not made for powerful output. Have to be redesigned from scratch. And we did not saw a driver
… …

Well something like an S2+ overheats at 8*7135 but 6*7135 isn’t too bad. There’s also the fact that the driver isn’t by the led in this light so the LED tube only needs to dissipate the wasted heat created by the LED itself. 2A at 3V shouldn’t be a stretch to dissipate in a tube light. It’ll get hot, probably 40-50c but that’s not the end of the world even if you touch it accidentally.

By host you mean, the structure of the spotlight? according to my idea it shouldn’t be a big deal a simple piece of plastic to fit with stronger light and driver.

I would gladly entrust the work in your hands, you seem very experienced, but in canada, I am afraid to see the project ready in a long time.

In case no one in Europe could do it, would it be so difficult to make it on your own? Maybe I could inquire about how to build it or ask for advice, I just need to know what to buy specifically.

Led Heatsink

What kind of connector does the light plug into the battery pack with? Is the black body, where the LED is, made of plastic? If you can swap the LED pcb on your own, and there’s no extra circuitry in the LED host, I could probably make you a new battery pack with the driver included.

Or you could do it on your own. I would buy something like these DIY battery cases and connect a driver to it with an output that fits your current headlight plug. This would result in usb charging, higher brightness, and probably a longer lasting battery.

Except you’ve got to put a driver somewhere in line with that and premade ones are optimized for space saving. Something better quality would be ideal, but in the end it’s just a case to put batteries in.

if you mean the led with its MCPCB, I bought a new Samsung LH351D

Yes, the black spotlight is made of plastic, I am attaching a photo of the cable connection here, the wheel on the left allows on / off and the adjustment of the intensity.

In the case of the DIY battery, would the driver be inserted inside the case? in what position? Thank you

The only thing wrong is that the battery is of 3W and not 5

Yeah with the led host being made of plastic, it’s probably not worth modding. Plastic is more of an insulator and will keep the heat inside from coming out.

You could probably still run at at around 1A but I wouldn’t increase the power by much above that.

Thanks, appreciate the advice :+1:

So have I lost hope of making it more performant?

If you notice this 1000 euro Orascoptic led, it is also made of plastic

If I bought an aluminum spotlight, could it be done?

It can be modded but you can’t increase its power by too much otherwise the plastic might melt. I’d be willing to have a go at it, but chances are it’ll take at least 2 months to get it shipped to me and back unless you want to pay a lot for faster shipping.

You have to learn how to make things better. Read this forum for a month or a year to understand what is all about

I’m happy to tell you I was wrong, :person_facepalming: I was 100% sure it was plastic, but it’s actually metal, I don’t know exactly what if aluminum or steel or whatever

What was talking about about a separate battery with screws?

Yay, so there is some potential to get the heat out.

The screws bit was about making a new battery pack. I’d probably throw away the old one because it’s likely no good with Chinese manufacturers cutting margins as tight as possible.

is this risk avoided by being made of metal? or is there still a risk even with metal?

The plastic part starts from the support, from the blue arrows

Yes, there is still a risk of overheating with metal if you give a light too much power, but you probably won’t need that much power for this light.

The metal will help dissipate the heat outwards from the LED.

However, I would gladly entrust you with the work, but I fear it takes too long between various expeditions.

Would it be so difficult if I made it myself? or maybe entrusting some parts of the job to an electrician? would he know how to do it?

So I should buy a DIY battery and a driver. Could you recommend these two things specifically? based on the characteristics and considering the SAMSUNG LH351D WHITE 5700K HIGH CRI90 that will come to me, always avoiding the overheating factor

I think it would be fine with 1.5A, maybe 2A at most if the heat path is alright. That’s a lot of light, maybe even too much up close. The body would get hot, burning to the touch, but the LED would be fine. The problem is we don’t know what the inside looks like and the heat path might not be so good (unlikely I reckon).

I’m not familiar with the drivers available for battery operated high powered leds outside of the flashlight world. I don’t think there is much out there that would work well so I do recommend getting help from someone here.

I’d recommend a 7135 driver attiny 85 driver where you could load a modified anduril with only the ramping up and down, and solder that to a battery bank with the output connected to the 5.5mm port, which looks like what your light is using.

I would also recommend a 4000k sst-20 instead of the LH351D since the sst-20 will make red colours look a lot more accurate.

My hope is that someone in Europe will read this and be willing to mod it for you.

What might work pretty well is if you could get an adapter that plugs into usb power banks and uses that 5v dc to power a driver that is connected to your light’s dc port. You could just buy power banks to power your light
