Definitions

  • the invention relates to a signal light for rail vehicles with a Reflector, at least one light source for emitting light a first color, wherein the at least one light source in a Focusing region of the reflector is arranged.
  • German utility model DE 202 11 647 U1 is a signal light known for rail vehicles, with up to four bulbs are arranged within a reflector. These bulbs are designed as lights. Light of different colors gets through colored glass solenas in which the incandescent lights are inserted become. With the described signal light two signal light colors, specially white and red, are provided.
  • a signal light for rail vehicles is created can be realized with the additional signal colors, without affecting existing signal functions.
  • this is a signal light for rail vehicles with a reflector, at least one light source for emitting Light of a first color, wherein the at least one light source in a Focusing range of the reflector is arranged, provided at the outside of the focus area in the reflector, a light emitting Diode for light of a second color is provided, the light in an angular range of at least 180 ° radiates.
  • the dimensions of the additional light source with another color comparatively be kept low and beyond that by the Emitting light in an angular range of at least 180 ° uniform illumination of a signal disk despite the arrangement of light-emitting diode outside the focal point region of the reflector achieved. It is thus possible even signal lights already with several illuminants are equipped, with an additional light-emitting Diode to provide, realized with the additional signal color can be. Due to the small dimensions and the large radiation area the inventively provided light-emitting This diode can be arranged in the reflector so that the rest Signal functions of the signal light are not affected.
  • the light-emitting diode extends in comparison to the light only slightly into the interior of the reflector.
  • the light-emitting diode radiates in one Angular range of 220 °.
  • a uniform illumination a signal disk for example one in front of the reflector arranged lens, achieved, although the light-emitting Diode only slightly extends into the interior of the reflector and moreover located outside the focus area.
  • the radiation in an angular range of 220 ° leads at least partially to a multiple reflection of the light in the reflector, so that a good light distribution can be achieved.
  • the light-emitting diode is relative to an inner wall of the reflector so arranged that the angular range, in which the light-emitting diode emits light, symmetrical to a Inner wall of the reflector in the region of the light-emitting diode lies.
  • the signal light according to the invention This contributes to a uniform signal image, nevertheless the light-emitting diode is disposed outside the focus area is.
  • the illuminant emits white light and it is at least another, in the interior of the reflector protruding bulbs intended for red light. Furthermore can also be yet another, projecting into the interior of the reflector Be provided bulbs for dimmed white light.
  • the invention provides a signal light is created by the on the one hand as driving light headlight for white driving light, dimmed white headlight and used as a red tail lamp can.
  • driving light headlight for white driving light
  • dimmed white headlight for white driving light
  • used as a red tail lamp can for example optionally a green signal light can be provided.
  • the problem underlying the invention is also due to a signal light for rail vehicles with a housing, one in the Housing arranged reflector, at least a first light source for white light of a first color, the at least one first Illuminant is arranged in a focal point region of the reflector, and a second, projecting into the interior of the reflector Bulb for red light dissolved, at the outside of the reflector on Housing at least one light emitting diode with upstream optics is intended for light with red and white different color.
  • FIG. 1 shows a signal light 10 with a reflector 12 and arranged in front of the reflector lens 14th
  • a first light bulb 16 is arranged, For example, a halogen bulb.
  • a second light bulb 18 is arranged, but also in the direction of the focal point of the reflector protrudes.
  • the second light bulb 18 is intended for example for dimmed white headlights, the first light bulb 16 for white driving light.
  • the Incandescent lamp 20 is inserted into a red-colored glass dome 22, so when turning on the third light bulb 20, a red light signal is produced.
  • a red so-called phantom light by lighting To avoid the glass dome 22 with white light is between the Glass dome 22 and the first light bulb 16 a Abschattblech 24 arranged.
  • the attachment of another bulb, such as green Light, within the reflector 12 would affect the lead white and red signal functions.
  • another bulb such as green Light
  • a so-called side-emitting LED 26 provided outside the Focusing range of the reflector 12 protrudes into this.
  • the Reflector 12 remote from the rear side of the LED 26 is a heat sink 28th intended.
  • the LED 26 emits light in an angular range of 220 °, accordingly +/- 110 ° off.
  • An associated intensity distribution over the emission angle is shown in Fig. 2, wherein the relative intensity in percent is shown in degrees over the beam angle. It can be seen that the emitted light intensity is +/- 80 ° higher than at a radiation angle from 0 degrees.
  • the radiated light intensity drops outgoing from 0 ° initially to go through a local minimum at about 25 ° and then rises again to an angle of about 90 °. From 90 ° to about 110 ° radiation angles falls the emitted light intensity strong.
  • LED 26 Due to the special, shown in Fig. 2 light intensity distribution of LED 26 is at least partially multiple of this radiated light reflected at the reflector 12. Despite the arrangement of the LED 26 far outside of the focal range of the reflector 12 is characterized by a uniform illumination of the lens 14 and thus a uniform Signal image reached. Dashed lines in FIG. 1 several possible beam paths starting from the LED 26 shown. It can be seen that light rays starting from the LED 26 are radiated to the rear of the reflector 12, the reflector then be reflected once or twice and only then on the lens 14 hit. In addition, light rays reach the diffuser 14, without being reflected on the reflector 12. Overall results but not least due to the intensity distribution shown in FIG a uniform illumination of the lens 14 and thus a uniform signal image.
  • a side-emitting diode 26 in the reflector is arranged. Since the arrangement of the LED 26, the other signal functions only slightly disturbing, but can also have multiple LEDs 26 are arranged in the reflector, for example, several different Signal colors to realize.
  • a control gear for adaptation the operating voltage of the incandescent lamps 16, 18, 20 to the for the Operation of the LED 26 required operating voltage can be in a luminaire housing be integrated.
  • FIG. 3 is a signal lamp according to the invention shown according to another embodiment.
  • a signal light 30 has a housing 32 in which two reflectors with associated Lens discs 34, 36 are arranged, for different signal functions, are also provided with different signal colors. For example, with the signal light 30 signal functions with white light and signal functions can be realized with red light. Around in addition to these signal functions still signal light with red and white to provide different color is in the housing 32nd a light-emitting diode 38 with upstream optics 40 is arranged. The light-emitting diode 38 is shown only in dashed lines, since they in the plan view of Fig. 3 is not visible in and of itself.
  • the Light-emitting diode 38 is advantageously designed as a high-performance light-emitting diode and, as can be seen in FIG. 3, between the two Main reflectors 34, 36 arranged and at the same time with respect to their Center shifted upwards. In this area is between the two Reflectors 34, 36 in the housing 32 still room for the arrangement of LED 38 and the upstream optics 40 available.
  • 32 may be an operating device for adjusting the operating voltage of Illuminant in the reflectors 34, 36 to those for the operation of the LED 38th required operating voltage can be arranged.
