Zusammenfassung:	A light emitting diode (LED) lamp includes a tube having a transparent first section and an opaque second section. An LED disposed inside of the tube. The second section is has an inner surface having a light diffusive surface so that the LED light is diffusively reflected. The LED is disposed so that a total amount of direct light from the LED to the first section is smaller than a total amount of indirect light that is incident on the first section as a result of being reflected by the second section (i.e., scattered or diffused light). The LED is disposed so that a light axis of the LED points toward the inner surface of the second section. Une lampe à diode électroluminescente (DEL) comprend un tube ayant une première section transparente et une seconde section opaque. Une DEL se trouve à l'intérieur du tube. La seconde section présente une surface interne diffusant la lumière de sorte que la lumière de la DEL soit diffusée par réflexion. La DEL est disposée de sorte que le volume total de lumière directe de la DEL vers la première section soit inférieur au volume de lumière indirecte incidente sur la première section du fait de sa réflexion par la seconde section (par exemple, lumière dispersée ou diffusée). La DEL est disposée de sorte qu'un axe lumineux de la DEL pointe vers la surface interne de la seconde section.
