Vehicle warning lighting system
View Patent ↗An emergency light system for an emergency vehicle. The light system can have a low profile configuration for improved aesthetics and aerodynamics. Further the light system can be configured to allow for customization of the individual emergency lights and/or easy access to the individual emergency lights.
1. An emergency vehicle comprising:
a cab having roof presenting a sloped portion that slopes a vertical distance of at least 6 inches over a horizontal distance of 12 inches;
emergency service equipment located behind said cab; and
an emergency light system coupled to said sloped portion of said cab,
wherein said emergency light system has a maximum depth (Dmax) and a maximum height (Hmax), wherein the ratio of Dmax to Hmax is at least 1.25:1,
wherein said emergency light system comprises a base, a lens assembly, and a plurality of emergency lights, wherein said base is attached to said sloped roof portion, wherein said base includes a light supporting region comprising a plurality of emergency light supporting surfaces, wherein said a plurality of emergency lights are coupled to said emergency light supporting surfaces, wherein said lens assembly is coupled to said base and covers emergency lights, wherein said lens assembly comprises one or more lenses through which light from said emergency lights can pass.
2. The emergency vehicle of claim 1 , wherein said sloped portion of said roof slopes a vertical distance of at least 8 inches and not more than 16 inches over a horizontal distance of 12 inches.
3. The emergency vehicle of claim 1 , wherein said sloped portion of said roof slopes a vertical distance of at least 10 inches and not more than 18 inches over a horizontal distance of 18 inches.
4. The emergency vehicle of claim 1 , wherein said cab comprises a front windshield, wherein said sloped portion of said roof is located immediately above said front windshield.
5. The emergency vehicle of claim 1 , wherein said emergency vehicle is an ambulance comprising a patient compartment and said emergency service equipment is medical equipment housed in said patient compartment.
6. The emergency vehicle of claim 1 , wherein said emergency light system further comprises a hinge coupling said base and said lens assembly to one another, wherein said hing is configured to permit shifting of said lens assembly relative to said base between an open position and a closed position, wherein external access to said light supporting region is prevented when said lens assembly is in said closed position and external access to said light supporting region is permitted when said lens assembly is in said open position, wherein said emergency light system further comprises one or more releasable locking mechanisms for selectively locking said lens assembly in said closed position.
7. The emergency vehicle of claim 1 , wherein said base is configured to cover at least 4 square feet of said roof.
8. The emergency vehicle of claim 1 , wherein the ratio of Dmax to Hmax is at least 2:1, wherein said emergency light system has a maximum width (Wmax), wherein the ratio of Wmax to Dmax is at least 1.25:1 and not more than 3:1.
9. The emergency vehicle of claim 1 , wherein said emergency light system presents a central front edge point (A), a central rear edge point (B), and a central peak point (C), wherein an obtuse interior angle (θ) is defined between references lines extending from C to A and C to B, wherein θ is at least 100 degrees and not more than 170 degrees, wherein the external radius of curvature (Rp) of said emergency light system at said central peak point (C) is at least 2 inches.
