Canon News discovered yet another patent, this one discussing what appears to be a high powered flash that also includes continuous LED lighting.
As Canon News notes;
The mechanical design of the speedlite is quite developed in the patent application leading me to believe that the development is quite far along for this flash. This speedlite is also a hybrid speedlite that contains a LED portion for continuous lighting.
From the patent application we can tell that the patent is about keeping the flash cooler and thus protecting the flash discharge tube (and also LED longevity).
An object of the present invention is to provide a lighting device capable of protecting a member related to light emission from heat associated with light emission. A light source, a first optical member that transmits light emitted from the light source, and a light source that transmits light emitted from the light source are disposed between the light source and the first optical member. The second optical member and the air sucked from the first space, which is the inner space including the light source, on the light source side of the second optical member, and the first optical member and the second optical member. An air blowing mechanism that sends the air to a second space that is a space between the optical members.
In the images below, 401 and 402 are LED's where the flash discharge tube is 102. You can see from the air flow path that both the discharge tube and the LED's have air circulation around them.
When looking at the flash from the bottom we see the fan and the exhaust.
In what situation would it create enough heat as to worry about the flash tube or LED damage?
What's the problem with Li-ion AA batteries?
LEDs for continuous video lighting gets very hot. Cluster of many small LED chips doesn't get that hot , but not powerful. So Canon might use high watt big LED chip which gets pretty hot. When I experimented, 12v 10W chip gets very very hot even when lighted for a minute, but very bright.
And a six way electrical outlet splitter would do better? Or maybe a charger that accepts six LP-E6s at a time?
My present setup was a total of $1,700 (4 total batteries and chargers that came with them.). My Canon Speedlites cost $3,800 + 75 rechargeable AA batteries and a charger, + the Westcott gang them up things. Canon's flashes are very very nice. They just don't have the power I need and the batteries are a PITA. So is mounting them on the gang thing (can't remember what it is called). ;)
The charger below comes with 3 batteries for the AD200. The charger handles 6. $247
My impression was you had seven speedlites, so you would need a six way splitter to charge six speedlites at the same time.
So you do use a six-way battery charger. As you said, whatever works for you.
I personally love speedlites for some situations as you can just about hide them anywhere. No bulky battery packs or attached generators to deal with can be bliss.
I have six 600-EX-RT’s and four PCB Einstein’s along with a variety of ways of triggering them. I will not infrequently use all of them combined if that is what is needed, both types have their advantages and uses and like lenses I have favorites but demand flexibility so have more than I use regularly.
And whoever works in the Canon flash skunkworks is nothing short of a genius, first the RT system, which just works, and second the 430-EX-III AI, that thing is a killer little flash. Stick a 600 tube in an active cooled head with Ai bounce that is an RT Master and every event shooter worth a darn would need one on each body to control the remotes.
