    摘要： A multifunction lighthead for mounting to a vehicle includes several groups of LEDs arranged to provide distinct light emission patterns. Each group of LEDs and associated optics are selected and positioned to produce light emission patterns needed to meet lighting standards applicable to the vehicle. Such standards may require wide angle light emission, which is enhanced by supporting groups of LEDs that project away from the vehicle body, enhancing visibility of the lighthead from directions close to a plane defined by the body panel. The projecting support for the LEDs and optics for a wide angle light emission pattern may be employed to support LEDs arranged for ground illumination. Other groups of LEDs in the same lighthead may be arranged with optics to provide area illumination in support of arrest, search, triage or other emergency functions.

    摘要： A warning light includes a lens or cover is tinted with a grey or “smoke” tint that is not spectrally selective or alternatively referred to as “neutral density” in that it reduces transmission of all colors of light equally. The objective of the neutral tinted “smoked” lens is to reduce the conspicuity of warning lights when not in use. Ambient light penetration into the warning light is reduced by the proportion of tint and then light reflecting off the optical surfaces within the warning light are reduced again when passing through the tinted lens on the way out of the assembly. The resulting warning light appears dull and is less conspicuous than the same warning light or lightbar with a clear lens. The tinted lens or cover may include optical elements configured to re-direct light, and the entire lens or cover is molded from the same tinted plastic material.

    摘要翻译： 警告灯包括透镜或盖子，其具有不是光谱选择性的灰色或“烟雾”色调，或者称为“中性密度”，因为它减少所有颜色的光的透射。 中性有色“熏制”镜头的目的是在不使用时减少警示灯的显着性。 入射到警告灯中的环境光通过色调的比例降低，然后在通过组件的出口的途中穿过有色透镜时，警告灯内的光学表面反射的光再次减小。 所产生的警告灯显示为暗淡，并且与使用透明透镜的警示灯或灯条相比不太显眼。 着色的透镜或盖可以包括被配置为重新引导光的光学元件，并且整个透镜或盖由相同的着色塑料材料模制。
