Definitions
- the invention relates to an LED light signal, in particular LED railway light signal, with a signal generator for generating different colored points of light, wherein the LEDs as multi-color LEDs, in particular RGB LEDs - red / yellow / blue LEDs - thoroughlybil ⁇ det are.
- LEDs Light signals or LEDs on the basis of LEDs - light emitting diodes - instead of incandescent lamps are increasingly used in many areas, especially in railway signaling. LEDs are comparatively inexpensive, durable and bright. The trend is towards HLED - high current LED - whose light intensity is so high that even a single HLED emits enough light per light point to achieve the required brightness.
- an actual current monitoring for each light point can be additionally provided.
- SIL3 or SIL4 In order to be able to operate the light signal in safety level SIL3 or SIL4, it must be ensured that only the light spot is supplied with the intended color and that the other light points are not current-carrying.
- RGB LEDs are known - red / yellow / blue LEDs - in which three LEDs with the colors red, yellow and blue are integrated into one LED housing. Due to the nature of these RGB LEDs, it is difficult or impossible to determine, based on a current measurement, through which of the three LEDs the current flows. However, this is required to achieve SIL3 or SIL4.
- RGB LEDs it is possible to realize several colors in one light point.
- LEDs of the same color are always energized, so that the number of colors that can be displayed is also limited by the number of differently colored LEDs.
- RGB LEDs can be used to achieve a large number of colors, ie color locations, by simultaneously varying denominated LEDs are energized or controlled by PWM pulse width modulation ⁇ tion, resulting in mixed colors.
- This technology is already used for lighting and display purposes ⁇ .
- An adaptation to signal generator is problematic, however, because of the safety-relevant significance of the light signals, especially in railway operation, a sig ⁇ naltechnisch secure monitoring of both the light intensity and the color location is required.
- the invention is based on the object, a multicolored
- Signal generator has at least one optical sensor for fail-safe monitoring of the color locus and the light intensity. It is only through the safe detection of the optical parameters that it is possible to use RGB LEDs for light signals with very high safety requirements, in particular SIL3 or SIL4. On color-specific current measurements, which are not possible with RGB LEDs at all or only with great difficulty, can be dispensed with. Due to the tendency to light ⁇ stronger LEDs and simultaneously decreasing production costs, it is possible to use a single RGB LED instead of at least three individual HLEDs of different colors. The colors can also be safely mixed by signal technology.
- the safe monitoring is based on the separation of the control for generating the required color location and the reliable optical monitoring of the actually emitted light. There- This results in a two-channel safe system, the control usually can not follow safety-relevant ⁇ he follow, but the overall system can be classified as signal technically safe in the sense of SIL3 or SIL4 by the fail-safe monitoring of the expected function.
- At least two independent optical Senso ⁇ ren are provided. This ensures that changes in a measurement channel can be revealed.
- the error detection can be additionally supported by a method that he ⁇ increases and decreases the target brightness slightly in the tolerable range. If the actual brightness measured in the at least two channels follows the setpoint brightness as expected, a fault-free system can be assumed.
- the same principle can also be applied alternatively or additionally by varying the color location, whereby even higher safety requirements can be realized.
- the optical sensor has a plurality of color-specific individual sensors. The farbspe ⁇ zifische single sensor registered only a brightness of the signal or a light intensity when the light spot was driven with the associated color.
- the color-specific individual sensor can be realized, for example, by means of upstream color filters. In this way, a brightness sensor can be used, which is designed for the entire color range, ie for the entire visible light ⁇ spectrum.
- the upstream of the single sensor Color filter causes the single sensor to react only to a certain color.
- the optical sensor can but according to claim 3 as
- the output signal of the optical sensor must be evaluated taking into account the spectral sensitivity of the sensor with regard to the spectral composition.
- the sensor is connected according to claim 4 via a sensor amplifier and an A / D converter with a digital evaluation device, in particular a controller, for determining the actual color location and the actual light intensity.
- the optical sensor detects the emitted light.
- the sensor amplifier serves to amplify and calibrate the output signal of the optical sensor. By calibrating, physical properties, such as the sensitive ⁇ ness of the sensor or the input area of evaluation, be compensated.
- the output signals of the optical sensor may be normalized such that a conclusion on the color components is mög ⁇ Lich directly from the output signals.
- the adjustment values follow from the properties of the sensor.
- the environmental behavior, in particular ⁇ sondere the temperature behavior of the sensor during the generation ⁇ supply the tuning signal is taken into account.
- the adjustment can also be shifted from the sensor amplifier to the evaluation device.
- a sensitivity profile is stored in the controller.
- the sensor amplifier can thereby be simplified.
- the required hö ⁇ here dynamics of the input values the requirements to the A / D converter which is connected upstream of the controller increase.
- the evaluation device a generated by ambient conditions, particularly the ambient temperature-dependent feedback signal and forwards it to a control ⁇ factory, said interlocking side, a drive signal is generated for acting on the signal transmitter and means for comparing the feedback signal are provided to the drive signal.
- a suitable link with external influences such as temperature or ambient light
- physical properties of components eg. B. their temperature behavior, or the site, z. B. with respect to the ambient light conditions, are compensated, so that a feedback signal is signaled to the interlocking, which is directly comparable to the drive signal for acting on the signal generator.
- the interlocking thus always has reliable information about the proper functioning of the LED light signal.
- the evaluation device additionally has means for comparison of the actual color location and / or the actual intensity with a desired color location and / or a target light intensity, wherein deviations that exceed a threshold over ⁇ trigger an intrinsically safe reaction.
- the remindmel ⁇ -making to the interlocking can take place on the basis of monitoring or intrinsically safe reaction.
- the evaluation device calculates an expected sensor signal from the drive signal for the signal transmitter and the spectral sensitivity of the optical sensor. This nominal sensor signal is compared with the detected actual sensor signal. chen. The deviation is evaluated, where appropriate, a eigensi ⁇ chere reaction, eg. B. a fail-safe shutdown occurs. In case of failure, the evaluation ensures that energization follows replaced according to the fail-safe principle, ie in case of a light signal for Signalbeg ⁇ riffs indication that the red stop signal lights.
