A patent geared to video shooters has appeared, and this one shows LED lights being included with the pop-up flash on a DSLR. The LED’s would be on continuously while shooting video, while the flash would be there for still shooting.
This sort of innovation could be good for vloggers and anyone that needs to light up anything close for video when you’re in a pinch.
Japan Patent Application 2019-056787
when using LED which carries out a continuous light as a light source of a lighting system, the measure against the heat which occurs from LED serves as problem. If the measure against heat is not performed sufficiently, LED deteriorates for a short time and there is a possibility that it may become impossible for light volume to be deteriorated or to switch on the light. If it is a lighting system removable to a camera like a Patent document 2, in order to radiate heat in the heat which occurs from LED, it is possible to provide a radiation substrate with a large area, but in the type which has a pop-up function, it is difficult to provide a radiation substrate with a large area near the LED.
This seems like a feature that has a good chance to make it into a future camera, but as with all patents, there is no guarantee.
