Abstract
A lamp tube including a glass tube body having a cross-sectional geometry that is perpendicular to a length of the glass tube body with a substantially cylindrical perimeter defined by a sidewall of the glass tube body enclosing a hollow interior for housing a light source. The sidewall of the glass tube body that defines the substantially cylindrical perimeter including at least one pair of ridges on opposing sides of the substantially cylindrical perimeter. Each ridge of the at least one pair of the ridges includes an apex extending towards the hollow interior for the glass tube body.
Claims20
A tube structure comprising:
- a tube body defined by a sidewall of the tube body enclosing a hollow interior, the sidewall of the tube body including at least one ridge on an interior surface of the tube body, the at least one ridge comprising an apex extending towards the hollow interior for the tube body, and the at least one ridge extends continuously along at least a portion of a length of the tube body so that each of the at least one ridge have a ridge length that is substantially parallel to the length of the tube body, wherein from a perspective of an exterior surface of the sidewall of the tube body a divot is present corresponding to the ridge.
A tube structure comprising:
- a tube body defined by a sidewall of the tube body enclosing a hollow interior, the sidewall of the tube body including at least one ridge on an interior surface of the tube body, the at least one ridge comprising an apex extending towards the hollow interior for the tube body, and the at least one ridge extends continuously along at least a portion of a length of the tube body so that each of the at least one ridge have a ridge length that is substantially parallel to the length of the tube body, wherein from a perspective of an exterior surface of the sidewall of the tube body a divot is present corresponding to the ridge, wherein the at least one ridge retains an edge of a circuit board including a light source.
A lamp comprising:
- a tube body defined by a sidewall of the tube body enclosing a hollow interior, the sidewall of the tube body including at least one ridge on an interior surface of the tube body, the at least one ridge comprising an apex extending towards the hollow interior for the tube body, and the at least one ridge extends continuously along at least a portion of a length of the tube body, wherein from a perspective of an exterior surface of the sidewall of the tube body a divot is present corresponding to the ridge;
- and
- a light source present within the hollow interior of the tube body, the light source present on a circuit board having edges secured by the at least one ridge to a portion of the sidewall of the tube body.
