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.
Claims20
A lamp tube 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 of the sidewall is textured to increase light diffusivity and an interior surface of the sidewall is not textured.
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 of the sidewall is textured to increase light diffusivity and an interior surface of the sidewall is not textured;
- 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:
- treating a glass tube body with an abrasive media to increase a texture of an exterior 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.
