Virence VS35SP36 MCPCB - cost effective (High CRI) General Lighting solution

Knowledge and experience is priceless! :beer:

Well now back to work on the 4x4 and/or 3x3 E21A mcpcb and RRT01 mod :smiley: I think the mcpcb would be popular since it would be a direct swap into so many XHP70.2 lights in existence.

:AWRIGHT:

UPDATE 190729: Test Result

100+ watt LED wattage

Is there any way to have two isolated sets of LED’s on one board? I would like to have adjustible color temperature, so have alternating rows of 5000k LED’s and alternating rows of 3000k LED’s, where all the 5000k can be controlled separately from the 3000k.

No by default. But you probably can do it yourself by scraping the masking and make your own wiring path.

Hello clemence !

Any plans to bring such packages (more particularily the Optisolis based ones, as tested bu Maukka) in a complete bulb format (E27 based for instance)?

Yeah, I’m thinking to make circular DIY kit for light bulb retrofit. But the problem is in choosing universal sizing for the MCPCB. Would you like to participate in the research?
And one more thing: almost all light bulb’s diffuser are glued to the base. Not so easy to open for general public

[Clemence]

At the moment I can't think of a better dream solution than using R95 Optisolis to light my rooms. It's your fault, since you made me discover Jetµsolis!

So, you bet I'd be glad to help to find a solution to mod/create our own bulbs!

I know we have Bocian here that is creating some nice custom E27 bulbs, based on Citizen LEDs. He might be of help. Maybe by joining each of our BLF's talent we can build together the ultimate bulb.

I like the sounds: Ultimate bulbs. I’ll try to contact Bocian then. ….or any other light bulb manufacturers

Because of the nature of things, safety reasons and the manufacturer’s policy, LED bulbs are not intended to be opened and modified. There will be someone who does not know the basics of electrical rules and we have an electric shock and other problems :frowning:

I wish you luck with this too. The first question will be how many thousands of pieces you want to order in this configuration :smiley:

[quote=Bocian]

That’s so unfortunate :frowning:

[Clemence]

Clemence. send me PM about what You want to achieve/produce/sell. What materials, shape, mounts, expected power, way of light distribution (diffuser/reflector/TIR), electrical parameters (current, voltage, power) of Your LED module.

Hi Bocian,

Thanks for your response. This is not about me. I personally have an agenda for another project. So, I’m not going to be the person in charge for this one. Optisolis light bulb is indeed something I have in mind since last year. But at this point I can only provide special custom designed MCPCB and Optisolis LED. Since you already have some ready to use product, swapping an LED module should be easy. Your product use 36V Citizen, right? And being a light bulb, no specific optic is required, just an unidirectional diffuser bulb is needed.
In my opinion Fneuf should be person to arrange another BLF project for BLF ultimate light bulb project. He has done some researches deeper than most of us in this topic. Just like many BLF projects before, this could be a great pilot project for another greater ideas.

[Clemence]

Yes, I use mostly Citizen CitiLED 12s (~36v) 97 CRI. Some sample photos with E27 base:
5W/7,5W/9W, incandescent 75W:

9W, 12W:

18W:


Centrally embedded COB diode is located on the copper plate, but there is no problem to use other LED module (with a properly selected power supply, of course).

If an Optisolis E27 LED bulb ever comes to fruition, I’m up for at least 20.

Here is an example of ceiling lighting:



Sorry if I make a mess in Your thread Clemence.

No worries Bocian, it’s related. You can PM me the available space for the Optisolis board. Can you make the driver switch modes by tapping the input? Phillips use this method to switch between CW, NW, and WW. This way I can design a multi CCT copper board

[Clemence]

Interested in many. Please make it happen guys :laughing:

120V compatibility please!
