Compared to the legacy W900S, the manufacturer underscores such T880S features as shorter cab; improved visibility and lighter weight characteristics; five-piece hood made of RTM, a light material tougher and more durable than fiberglass; and, complex reflector
halogen headlight providing projector beam performance without the extra cost.
Then, in the late 1980s, Honda introduced complex reflector
lamps, which moved the responsibility for beam focusing back to a reflective surface and away from a lens.
Given a complex reflector
shape by the OEM, and with knowledge of the material properties, the system predicts how the components will distort under thermal load.
This requires the design and manufacture of complex reflectors
and light guides such as compound parabolic concentrators and trough concentrators.
