LIGHT EMITTING DIODE LAMP WITH LIGHT DIFFUSING STRUCTURE
First Claim
1. A light emitting diode (LED) lamp, comprising:
- a tube having a first section and a second section; and
LEDs disposed inside of the tube, wherein;
the first section is transparent or substantially transparent with respect to an LED light emitted from the LEDs,the second section has an inner surface having a light diffusive surface so that the LED light is diffusively reflected, andthe LEDs are disposed so that a total amount of direct light from the LEDs 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.

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.

35. A light emitting diode (LED) lamp, comprising:
-
a hollow member; LEDs disposed inside of the hollow member; and a reflector disposed inside the hollow member, wherein; each of the LEDs are disposed so that a light axis of each of the LEDs points toward the reflector, and a surface of the reflector on which light emitted from the LEDs incidents has a structure to diffuse or scatter the incident light. - View Dependent Claims (36, 37)
