Abstract
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.
