It's interesting, it seems like 4W of blue would massively overbalance 130mW of green, even with eye sensitivity factored in.I was talking to LG display about projection technology on Friday with one of the engineers. Apparently LG is in the process in obtaining 4W 450nm diodes by a company called SORAA. Anyone know this company? LG will be producing a "pico-projector" using the 4W 450nm diodes and another true green LD diode with a peak emission at 130mW.
Apparently some of the new projectors already have the 4W diodes in them. It's likely some of you laser enthusiasts already have them in your possession, and don't even realize it yet. i have a feeling someones going to discover this by testing soon.
I wonder what the release date will be for that?I think I made a mistype...
The technician was talking about two different projectors.
The small "pico" projector will be using the Green diode from SORAA, the other projector a larger 4000 lumen projector will be using the 4W diodes from SORAA. It too will be part of a compact line of projectors. "Green projectors"
Basically the projector 4W SORAA diodes are in circulation right now. This comes directly from the engineer staff over at LG display.
These guys are very interesting to talk to! I have learned lots about the science behind display technology. It's amazing stuff!!
Same here I don't know about when that might be released. However I think I may ask a little bit more about the new DLP technology tomorrow and maybe by tomorrow evening have some more answers for you on that question.I wonder what the release date will be for that?
And also whether they're using it for blue channel only, blue and green, or just green. And in any event, what they'll use for red?
(Mitsubishi 8W 635 array might be a logical pairing for the 4W Soraa)
This should not be overly difficult to determine: If someone has a few of these diodes on hand, its easy to see if the barcodes are -identical- by naked eye. In that case they cannot be a serial or something containing diode specific data.It's an H-Series. If I get really ambitious at some point, I'll do the same with another diode from the projector. It would be valuable to know whether the number:
- Increments (suggesting that it's just a serial)
- Stays identical (suggesting a batch number, manufacture date, revision, etc)
- Is wildly difference (suggesting that the data may represent some diode-specific characteristics)
The A-series is different from the M and H series.Hi, everybody!
I am sorry for my bad English) looked this subject, but and did not understand, how marking of diodes of M - and a H-series differs? Whether there is at them a difference in output power? Or it is the same diode?
