Abstract: A lamp is provided that includes a glass tube body composed of a glass composition that includes an optical diffusive agent to increase the light diffusivity of the glass tube body. The lamp can include a glass tube body having a perimeter defined by a sidewall of the glass tube body for enclosing a hollow interior. The glass tube body is composed of a sodium silicate glass including an optically diffusive agent that is alloyed with a silicate base glass composition. The optically diffusive agent can be selected from lithium borosilicate, titanium dioxide, antimony trioxide or combinations thereof. The lamp can further include at least one light emitting diode (LED) on a substrate that provides the light source. The at least one light emitting diode (LED) that is present on the substrate is positioned within the hollow interior of the glass tube body.

Abstract: A lamp tube is provided for lamps, such as lamps including light sources including light emitting diodes (LEDs), in which the exterior surface of the lamp tube's glass sidewall has been abrasively treated to increase the exterior surfaces roughness, which increases the light diffusivity of the glass lamp tube. In one embodiment, the lamp tube provided herein includes a glass tube body having a perimeter defined by a sidewall of the glass tube body for enclosing a hollow interior, in which the exterior surface of the sidewall is textured to increase light diffusivity. The interior surface of the sidewall of the glass tube body is not textured.
