Traffic lane marking device

Claim 2

A night-visible traffic marking device for installation embedded into aircraft landing strips, vehicle roadways and the like, comprising: a generally planar plate member of transparent material installed with its upper surface flush with the traffic contacting surface; at least one night visible object upstanding within the plate member to provide a substantial vertical profile from the point of view from an oncoming vehicle, the side of said object facing the vehicle including material selected to be highly visible when impinged upon by light; light-emitting means positioned within the transparent plate member to illuminate the vehicle facing side of the upstanding object during periods of darkness; wherein said device includes power generating means self-contained therein, including a photo-voltaic panel imbedded within the transparent plate member and positioned to receive sunlight therethrough so that a voltage is generated during at least a portion of each diurnal period; battery means chargeable by current from voltage from the panel; light-emitting means powered by the battery means and positioned to illuminate the vehicle facing side of the upstanding object; normally open light triggered switching means controlling power transmission from the battery means to the light-emitting means; wherein the transparent plate includes a recess; and the light-emitting means is carried within a module removably installed within the recess.

Claim 3

A night-visible traffic marking device for installation embedded into aircraft landing strips, vehicle roadways and the like, comprising: a generally planar plate member of transparent material installed with its upper surface flush with the traffic contacting surface; at least one night visible object upstanding within the plate member to provide a substantial vertical profile from the point of view from an oncoming vehicle, the side of said object facing the vehicle including material selected to be highly visible when impinged upon by light; light-emitting means positioned within the transparent plate member to illuminate the vehicle facing side of the upstanding object during periods of darkness; wherein the transparent plate member extends a sufficient distance toward the direction of vehicle approach to enable light therefrom to fully illuminate the night-visible object from substantial distances; wherein said device includes power generating means self-contained therein, comprising: a photo-voltaic panel imbedded within the transparent plate member and positioned to receive sunlight therethrough so that a voltage is generated during at least a portion of each diurnal period; battery means chargeable by current from voltage from the panel; light-emitting means powered by the battery means and positioned to illuminate the vehicle facing side of the upstanding object; normally open light triggered switching means controlling power transmission from the battery means to the light-emitting means; wherein the transparent plate includes a recess; and the light-emitting means is carried within a module removably installed within the recess.

Claim 4

A night-visible traffic marking device for installation embedded into aircraft landing strips, vehicle roadways and the like, comprising: a generally planar plate member of transparent material installed with its upper surface flush with the traffic contacting surface; at least one night visible object upstanding within the plate member to provide a substantial vertical profile from the point of view from an oncoming vehicle, the side of said object facing the vehicle including material selected to be highly visible when impinged upon by light; light-emitting means positioned within the transparent plate member to illuminate the vehicle facing side of the upstanding object during periods of darkness; wherein the transparent plate member extends a sufficient distance toward the direction of vehicle approach to enable light therefrom to fully illuminate the night-visible object from substantial distances; wherein said device includes power generating means self-contained therein, comprising: a photo-voltaic panel imbedded within the transparent plate member and positioned to receive sunlight therethrough so that a voltage is generated during at least a portion of each diurnal period; battery means chargeable by current from voltage from the panel; light-emitting means powered by the battery means and positioned to illuminate the vehicle facing side of the upstanding object; normally open light triggered switching means controlling power transmission from the battery means to the light-emitting means; wherein the transparent plate includes a recess; and the light-emitting means is carried within a module removably installed within the recess.
