Embodiment Construction

[0018] Referring to the drawings, wherein like numerals designate like or corresponding parts. A representative automobile 10 is shown in FIG. 1 . The automobile 10 includes a rearwardly facing exterior surface provided with a rear window 12, a pair of rear brake light assemblies 14, and other standard features. CHMSL assembly 16 is mounted on vehicle 10 to be visible through rear window 12 . When the driver touches the brake pedal and thereby activates the brake system, the CHMSL assembly 16 is activated, together with the brake light 14, illuminating an extended, generally rectangular red area to signal brake-sensing deceleration to drivers behind Signal.

[0019] Referring to FIG. 2 , the CHMSL 16 includes a housing 18 mounted or secured to the vehicle 10 . In some vehicles, the housing 18 hangs from the interior roof or roof portion, however, in other vehicles, the housing 18 is mounted on the trunk lid of the vehicle or on the exterior trunk of the vehicle. Certainly,...

Abstract

A CHMSL (16) or other lighting system feature of an automobile (10) includes a feature for presenting personal expressions in the form of words or symbols but is automatically deactivated when the regular vehicle lighting system is in use. The personal expression is fixed in a tangible medium by way of phosphor-coated indicia (34) placed within a UV impervious housing (18). A secondary UV light source (36) selectively energizes the phosphor-coated indicia (34) so that the irradiated material glows and is visible through a light transmissive screen (20). The light transmissive screen (20) is provided with a UV blocking agent so that harmful UV rays do not escape the housing (18). The phosphor-coated indicia (34) can be mounted on a removable transparent plate (30), on light dispersion optics (24, 26), or on the inner face of the light transmissive screen (20). A control circuit (42'') manages the primary light source (22) and the secondary UV light source (36) so that only one of the light sources can be energized at any one time.

Description

[0001] Related application reference [0002] This application claims priority to US Provisional Patent Application No. 60 / 588,481, filed July 16, 2004. field of invention [0003] The present invention relates to ultraviolet light sensitive markings for motor vehicles, in particular to a parking or other exterior lighting system capable of displaying ultraviolet light sensitive markings when irregularly used as a parking or other light component. Background technique [0004] The center high mounted stop lamp (CHMSL) assembly of a motor vehicle is an example of a conventional lighting assembly whose primary purpose is to indicate braking conditions. Typically, a central overhead stop light assembly is mounted in the rear window or on the rear deck of a vehicle, connects to the brake light system, and illuminates an extended, usually rectangular area. The central overhead stop light assembly provides enhanced visibility to the brake light system and thus forms an important ...
