Light bar

A light bar for mounting on an emergency vehicle to provide warning light signals, comprising at least two vertically spaced lighting layers, each layer having at least one light source, the light sources on each layer cooperating to provide a transient high intensity warning light signal 360.degree. around the light bar. The light bar may include oscillating light sources. A casing encloses the light sources, and a divider separates the light sources of at least two of the layers and divides the casing into at least two vertically spaced layers. The divider includes means for permitting air convection between the layers while blocking direct light transmission from the light sources on one layer to the other layer. The casing comprises upper and lower shell members which interfit to horizontally compress a gasket to seal the casing without screws or other fasteners penetrating the shells. The light bar preferably includes a hollow tube extending substantially the length of the light bar, for mounting the light sources. The tube may be formed by upper and lower channel shaped members. A plurality of stationary lights can be incorporated into one of the layers of the light bar, and electronically controlled to provide traffic directing signals.

A base adapted to be mounted on a vehicle supports a light source for generating a rotating light beam. A dome-shaped lens is positioned on the base over the light source to form an enclosure for the light source. A coating may be located on the top of the lens to prevent light passing therethrough and into the passenger compartment. Multiple flashes are created by a reflector positioned adjacent the rear portion of the lens to reflect the rotating beam as a plurality of discrete flashes within a sector relative to the base. A filter generally having a contour of the front portion of the lens may be mounted thereon. The multiple flashes may be of different colors depending on the range of wavelength of light transmitted by the lens and filter and reflected by the reflector. A person viewing the light sees at least four discrete flashes of light which may be of varying colors.

Multicolor emergency vehicle light

A light bar for emergency vehicles, comprising a relatively thin flat elongate base adapted for mounting thereon a plurality of electrical and mechanical components such as lamps, a siren and the circuitry therefor and an array of holes in the base extending lengthwise of the base adapted to receive fasteners for mounting the components on the base. The holes are of such number and so arrayed as to accommodate any one of a multiplicity of component configurations. The light bar further comprises sealing means extending lengthwise of the base over the holes for sealing the holes and a plurality of fasteners threadable through the sealing means into specific holes in the array of holes for fastening selected components to the base in a predetermined configuration. The other holes in the array remain sealed by the sealing means.
