I'm planning to mount LED strips under the treads of the outdoor wood staircase to our back yard. I'd like to avoid light shining into peoples' eyes while climbing stairs, so I'm considering mounting the LED strips in a 45-degree aluminum channel with the beam pointing back at the risers. My goal is to make the light source effectively invisible, even from the bottom of the staircase. Here's a not-to-scale rough idea of what I have in mind.
Is this a bad idea for any reason? For example, is it dangerous if most of the illumination is on the riser and the back part of the tread instead of on the front part of the tread where people step onto? Or is it more safe because people won't be blinded by the lights so are less likely to trip?
I've never seen LED strips mounted like this so I'm a bit nervous about it. But I also really like the way it looks! Here's a mockup I built tonight.
