[Lab] AC adapter question

A little question about AC adapters.
I have an artwork that I did that I used an AC adapter to get power. It
was on for 4 days during a show, and I was surprised on how hot it got. (I
almost burned myself). I did have duct tape on it holding it to the back
of a wall, so that may have been half the problem.
I'm showing the work again, but I'm wanting to make sure everything is
safe. I need to hide the adapter due to aesthetic reasons, so I wanted to
create a little white box around it with air holes, and I was suggested a
fan, although it if it getting hot due to over working, adding another fan
might not be a good idea.
It is only a bunch of IR leds that it is powering, so I'm surprised at the
power I am needing.
any help would be very well appreciated.
Here is the Adapter I used :
Here are the IR LEDS:
And the Resistors I have on them were 91 OHM 1/4W 5% CARBON FILM.
