I'm trying to make a stationary remote control that doesn't have to move. Basically I need to use a high intensity IR LED (I think). I'm assuming if the LED is not facing the TV etc. it will bounce around the room more effectively if its more intense. However, I'm a little worried after reading the datasheet for SFH 4550. It says:
"Depending on the mode of operation, these devices emit highly concentrated non visible infrared light which can be hazardous to the human eye"
Do I actually need to be worried about eye damage? Is there a way to avoid it causing damage (a filter over the LED?)
