When one of the first and second central illuminance controllers 140 and 240 mounted on the first locomotive 110 or the second locomotive 210 is operated as a master central illuminance controller according to the traveling direction, The first and second illuminance sensors 130 and 230 installed inside or outside the front windows 112 and 212 of the first locomotive 110 or the second locomotive 210 sense the intensity of sunlight and detect the illuminance value Converts it into an electrical signal and transmits it to the master central illuminance controller (S110).

At this time, the master central illuminance controller may control the illuminance control signal for controlling the internal illuminance of the first and second carriages 120 and 220 in accordance with the detection results of the first and second illuminance sensors 130 and 230, 2, respectively, to the controller 150 and 250 (S120).

At this time, at the initial start of the railway vehicle, the illuminance control signal is divided into a first multistage (for example, 50% -70% -100%) or a second multistage (for example, 70 % -100% -130%) of the illuminance value that matches the currently sensed illuminance value.

Then, the first and second passenger car intensity controllers 150 and 250 receive the intensity control signal transmitted from the first or second central intensity controller 140 and 240, and transmit the received intensity control signal to the first and second LEDs To the lamps 160a and 260a (S130).

At this time, the illuminance of the LED lamps 160 and 260 is adjusted to a matched illuminance value among the preset multi-stage illuminance values according to the illuminance control signal through the converter provided inside the LED lamps 160 and 260. In this case, It is possible to adjust the illuminance of the LED lamp by applying it variably.

Accordingly, even if the number of the LED lamps 160 and 260 increases in each of the first and second passenger cars 120 and 220, not only the entire communication control line can be easily configured, but also the communication control line can be expanded, It can be done easily.

If the current switching mode is set to the second switching mode, the first or second central illuminance controller 140 or 240 may increase the brightness of the first multi-stage illuminance value preset in advance in the first switching mode And transmits the roughness control signal to the first and second passenger car intensity controllers 150 and 250, the roughness control signals being adjusted to a preset second multistage roughness value to be adjusted.

For example, in Table 1, when the first or second illuminance sensor 130 or 230 detects 200 lx or less, if the current switching mode is set to the second switching mode, it is not 100% of the design value but 130% It is regulated.

In this way, it is possible to further increase the lifetime of the LED lamp, and even if the illuminance of a specific room suddenly deteriorates during the operation of a railway vehicle, LED lamp can be effectively controlled.

In the preferred embodiment of the present invention, as shown in FIGS. 7A and 7B, when the multi-stage illuminance value is changed from the dark stage to the bright stage, the brightness change point is hysterisis It is desirable to design it to have curve graph characteristics.

In the graph shown in FIG. 7A, when the room is set in advance so that the brightness is changed to three levels in the automatic mode, it is known that the brightness is gradually changed without changing abruptly when the illumination is changed. In the graph shown in FIG. It can be seen that the reference value at the time of changing the brightness is controlled so as to have the hysteresis characteristic so that there is no flicker of brightness.

The illuminance level may be set by a communication port on the front panel of the first or second central illuminance controller and a large amount of the vehicle illuminance controller, so that the driver can program to adjust the illuminance level of the multi-stage.
