There are plenty of LED mounting solutions out there depending on the specific LED. For example look at these solutions. Lower right on the linked page. Those are just an example. As to a star shape? This is something you would make on your own using mounting solutions. Another method is for example using surface or board mount LEDs where you fabricate your own circuit board in a shape of your choosing.
In conclusion it depends on the type and size of the LED you want to work with.
Thanks, great place man. I can not believe I have not heard of these guys.
I see that all these housings have the actual star LED included. I've been doing some design's and I purchase the star LED alone. So I thought there would be some common enclosures that one could buy and fit my star LED in them.
But thanks again, maybe I will just have to buy a complete unit.
