I guess look for flashlight/torch optics designs. Maybe just take the head off of an existing commercially built tactical flashlight/lamp to see that it does have a glass or plastic lens element to focus the beam. Look up any "LED calculator" to figure out how to configure and power your array of LEDs. You would have look through the specs or datasheets of available LEDs to see if you get the output you want. Maybe a single element LED would do instead of the 7. High power LEDs do require a driver board so you don't burn out the LED and you would have to take heat dissipation into account for the enclosure. Mounting options are many from fixed to variable with tube or handlebar mount. Good luck.
