Light emitting diode tube lamp including glass lamp tube with self diffusive tube glass and method of forming self diffusive glass using chemical etching

A lamp comprising:

• 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 and the interior surface of the sidewall is textured to increase light diffusivity;
• and
• at least one light emitting diode (LED) on a substrate that provides the light positioned within the hollow interior of the glass tube body.

A method of lamp assembly comprising:

• etching a glass tube body to increase a texture of a surface of the sidewall of the glass tube body, the sidewall of the glass tube body enclosing a hollow interior;
• and
• positioning a circuit board including a plurality of light emitting diodes within the hollow interior of the glass tube, wherein the increase in the texture of the exterior surface increases the light diffusivity of the glass tube body.
