1. A combined lens and safety enclosure apparatus for a light-emitting diode (LED) module, the enclosure apparatus comprising:
at least one plastic-material-based optical-lens element mounted over a plurality of LED elements, a distance between the optical-lens element and any portion of any one of the plurality of LED elements being spaced away from each other by at least 0.8 mm;
a driver-on-board (DoB) subsystem; the DoB subsystem including an electronic circuit configured to provide power to the plurality of LED elements;
a plastic-material-based optical enclosure mounted over the DoB subsystem, a distance between the plastic-material-based optical enclosure and any portion of any of the electronic circuit being spaced away from the plastic-material-based optical enclosure by at least 0.8 mm; and
a sidewall-separation portion surrounding the DoB subsystem and below the plastic-material-based optical enclosure, the sidewall-separation portion to provide mechanical reinforcement and prevent accessibility from side portions of the LED module.
