Canon News found one more patent, this one discussing what seems to be a excessive powered flash that additionally contains steady LED lighting.
As Canon News notes;
The mechanical design of the speedlite is sort of developed within the patent software main me to consider that the event is sort of far alongside for this flash. This speedlite can also be a hybrid speedlite that incorporates a LED portion for steady lighting.
From the patent software we are able to inform that the patent is about protecting the flash cooler and thus defending the flash discharge tube (and in addition LED longevity).

The second optical member and the air sucked from the primary area, which is the internal area together with the sunshine supply, on the sunshine supply aspect of the second optical member, and the primary optical member and the second optical member. An air blowing mechanism that sends the air to a second area that may be a area between the optical members.
In the photographs beneath, 401 and 402 are LED’s the place the flash discharge tube is 102. You can see from the air move path that each the discharge tube and the LED’s have air circulation round them.
When wanting on the flash from the underside we see the fan and the exhaust.
