Canon Patent For High Power Speedlite Flash With Air Cooling

Canon Patent For High Power Speedlite Flash With Air Cooling

After the Canon patent application for a lens with built in vacuum cleaner, here is another interesting patent application filed by Canon.

Canon patent application 2019-185021 (Japan) discusses a high power flash unit with a built-in air cooling system. Air is sucked into the flash unit, passes through or around the flash head (the part that gets hottest) and is then put out. Effective cooling system.

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.

More Canon patent applications are listed here. Some particularly interesting patent applications we think might get into production are these:
