1. Led lenses and reflectors for LEDs (solid-state lighting) is much different than just scaling them down from other light sources.
2. When talking about lens optics the larger the optic the easier it is to collimate light into a tighter pattern. Another consideration when trying to achieve a tight spot is the size of the LED die. The smaller the size of the die the tighter the spot.
3. Optical efficiency is determined by measuring the ratio of light collected after the optic and dividing by the total amount of light without an optic directly at the LED source.
4. Typical spatial distribution is what manufacturers use to describe the light coming from an LEDs primary optic.
5. Secondary optics are used to collimate the light rays into a controlled beam that will bring that full intensity to the area you need.
6. Collimated light rays spread in parallel, although it is impossible to make the light perfectly parallel because of diffraction and the finite physical size of the bare emitter. It is important to note that the smaller the light source (emitter), the more effective the process will be.
