- The desk lamp was developed to illuminate a work surface. Desk lamps are typically designed with down-pointing shades held on height and pivot-adjustable arms. The bases are typically stout to support the cantilevered weight of the shade. The light is focused on the work or reading surface; the lip of the shade is below eye-level.
- Diaper Pattern
- A cross-hatched, low-relief surface decoration pattern.
- Diffuser

- Dome
- A partial or full-hemisphere for diffusing or reflecting light. See also “Bowl” and “Inverted Dome Chandelier”.
