摘要： A beam spreading device for use with a centralized lighting system and which can be applied to emergency vehicle lighting applications achieves a beam pattern light output which is essentially continuous over an output range of plus and minus 45 degrees from a center point. The beam pattern light output also has a predefined height associated therewith. The beam spreading device is constructed so as to have a curved surface which mixes the light travelling therethrough so as to achieve the continuous light output. Side wall surfaces of the beam spreading device provide for total internal reflectance properties of the beam spreading device. In one embodiment, a color wheel can be interposed between the output of optical fibers which transmit the light from the centralized light source to the necessary remote location, and the beam spreading device. The color wheel provides the ability to generate different color light outputs from a single light source. In another embodiment, the side wall portions are curved to enable significant packaging depth advantages.

摘要： A lighting system and method for broadcasting colored lights as emergency warning signals from a light source. A centralized continuous light source is coupled via a fiber optic transmission medium to an external display location such as a lens or the like located on a vehicle. The color and the relative intensity of each color is periodically modulated to alternate between at least two states such that the contrast between these alternating states is perceived by observers to be a flashing source of light with no off-time. The frequency and the duty cycle of the repetition rate of alternating between the states may be further controlled to better draw attention to the light source.

In one embodiment, the external display locations include optical converters, each converter having multiple input facets and optically arranged to broadcast light received at its facets at predetermined vertical and horizontal output angles.
