A rail signal having a rail signal lamp with a lens assembly comprising: a light emitter panel having an inner panel portion and a surrounding outer panel portion, wherein the inner panel portion is provided with an inner plurality of light emitters and the outer panel portion is provided with an outer plurality of light emitters, and a lens plate covering at least the outer panel portion and provided with a plurality of lens elements aligned with light-emitters in the outer panel portion, wherein the lens assembly provides light from the outer plurality of light emitters with a narrower divergence than the light from the inner plurality of light emitters.

A light signal, in particular for rail-bound traffic routes, includes a light source, an optical system and a control device for adjusting an emission characteristic. In order to improve the way optical parameters, in particular regarding brightness, phantom light and path geometry can be adjusted, the control device is configured to adjust the transmission properties of at least one smart glass element disposed in the luminous or light flux.

A light stick, primarily useful in the locomotive industry for signally between train personnel, includes a longitudinally extending housing which contains a first light source and a second light source. The first light source provides for general purpose illumination of the light stick. The second light source provides illumination primarily for purposes of signaling. The light stick may include a lens cap which is positioned at a forward end of the housing, and from which the illumination from the second light source may extend. Preferably, the light that is emitted from the lens cap has a blue color for purposes of railroad signaling.

A rail signal having a rail signal lamp with a lens assembly comprising: a light emitter panel having a plurality of light emitters; and a lens plate covering the plurality of light emitters and provided with lens elements aligned with the light-emitters, wherein the lens elements have a rear surface facing a respective light emitter and an opposed front surface, and the front surface is rotationally symmetric about a Z axis that is parallel with an optical axis of the lens element, has orthogonal X and Y axes; wherein the rear surfaces each have a plurality of concavities in the X-Z plane, having a mirror symmetric arrangement of a first concavity between two second concavities, wherein the centre of the first concavity is aligned with the optical axis, and the second concavities have a larger radius of curvature than the first concavity.

A light emitting diode (LED) traffic signal light module is provided. The LED traffic signal light module comprises a housing, an LED module, a power supply module and a lens set. The LED module is disposed on an inner wall in the housing. The power supply module is disposed in the housing, wherein the power supply module is electrically connected to the LED module. The lens set is disposed on the housing.
