In addition, the light sensor switch (Dimming Switch) 213c is used to control the current to adjust the ON/OFF of the electroluminescent sheet 220 and the intensity of light.

Here, the light sensor switch 213c is, for example, turned on when rotated in a clockwise direction and at the same time strongly controls the light, and when rotated in a counterclockwise direction, the light is adjusted weakly and at the same time fully rotated in a counterclockwise direction. turns OFF.

In addition, the illuminance controller 213 is a PLD (Programmable Logic Device) or FPGA (Field Programmable Gate Array) micom (μ-com), and the micom has a predetermined for controlling the on / off operation of the electronic light emitting sheet 220 program is embedded.

Therefore, the visibility of the information shown on the display sheet 230 is adjusted as needed so that the driver can find each rotary switch 211 and push button 212 mounted on the control panel 200 more easily and quickly. At the same time, it can reduce eye fatigue for drivers who drive for a long time.

The electroluminescent sheet 220 is coupled to the base panel 210 and configured to emit light when power is supplied, and each of the rotary switches 211, the push button 212 and the optical sensor A plurality of rotary switch accommodating holes 221 and a push button accommodating hole 222 are formed to accommodate the switch 213, and around the rotary switch accommodating hole 221 and the push button accommodating hole 222 are A plurality of light projection units 223 for projecting light are formed.

In addition, the light projection unit 223 is formed in a straight line, curve, or square line at predetermined intervals to the upper, lower, left, and right sides of each rotary switch 211, push button 212, and optical sensor switch 213c. It can be formed to achieve.

In addition, the electroluminescent sheet 220 has an optical sensor switch accommodating hole 224 formed in the base panel 210 to accommodate the optical sensor switch 213c, and the optical sensor A plurality of light projection units 223 are formed to project light to the periphery of the switch accommodating hole 224 as well.

In addition, the rest of the electroluminescent sheet 220 except for the light projection part 223 is formed to be shaded and shadowed so that light is not projected.

In addition, the electroluminescent sheet 220 is a phenomenon in which fluorescence appears when a strong electric field is applied to a solid, which is constituted by electroluminescence in which electrical energy is converted into light energy.

To this end, the electroluminescent sheet 220 is a NeonFlex TM composed of dielectric, phosphor, and electrode layers integrated within a thickness of 10 mm, specifically, a polyester transparent film having a flexible property, and a predetermined thickness on the back of the transparent film A front electrode layer having excellent light transmittance and conductivity, a fluorescent layer formed on the rear surface of the front electrode layer to a predetermined thickness and inducing electroluminescence, and a dielectric layer formed on the rear surface of the fluorescent layer to a predetermined thickness and having electrical insulation and light reflection effects. And, a back electrode layer laminated to a predetermined thickness on the rear surface of the dielectric layer, a protective layer of a predetermined thickness integrally formed on the rear surface of the back electrode layer to protect from moisture and ultraviolet rays, and a front electrode layer and an electrode formed on one side of the back electrode layer. Consisting of it is desirable

Here, the front electrode layer is preferably a conductive mesh layer, and the conductive mesh layer is preferably formed by coating a conductive material having a predetermined thickness on the surface of polyester yarn having excellent tensile and elastic properties.

In the electroluminescent sheet 220 having this configuration, when an AC voltage output through a separate converter 213a and an inverter 213b is applied to the electrodes of the front electrode layer and the rear electrode layer, electrons in the fluorescent layer are excited, and the excited electrons While being stabilized at a low energy level, light is emitted to the outside through the transparent front electrode layer.

In addition, by applying the AC power of a predetermined frequency output through the separate converter 213 and the inverter 213b, electrons are repeatedly excited and stabilized to continuously emit light.

As such, the electroluminescent sheet 220 is capable of uniform surface light emission, is non-heating, is thin and light, emits short-wavelength light, has excellent visibility, and has excellent power consumption.

The indicator sheet 230 is detachably attached to the front surface of the electroluminescent sheet 220, and a plurality of rotary switches can accommodate the rotary switches 211 and the push buttons 212. An accommodating hole 231 and a push button accommodating hole 232 are formed, and each rotary switch 211 and a push button 212 are formed around the rotary switch accommodating hole 231 and the push button accommodating hole 232. A figure and a text part 233 are formed.

In addition, the display sheet 230 has an optical sensor switch accommodating hole 234 to accommodate the optical sensor switch 213c formed in the base panel 210, and the optical sensor switch accommodating hole 234 A figure or character 233 is also formed around ).

In addition, the display sheet 230 plays a role of evenly diffusing the light emitted from the electroluminescent sheet 220 through the light projection part 223 and figures and characters 233 except for the shaded part of the electroluminescent sheet 220. do.

To this end, the display sheet 230 includes the light projection part 223 excluding the shaded part of the electroluminescent sheet 220 and the figure/character part 233 in order to diffuse the light emitted from the electroluminescent sheet 220. Preferably, a light diffusion film (not shown) is formed.

In addition, diffuse reflection protrusions (not shown) may be formed on one surface of the light diffusion film of the display sheet 230 so that light emitted from the electroluminescent sheet 220 is diffused to the surrounding area while being diffused.

In addition, spherical lenses (not shown) may be attached to the light diffusion film to diffusely reflect transmitted light.

In addition, the display sheet 230 according to the present invention is less prone to scratches due to the nature of the material, so maintenance costs and time can be reduced.

That is, since the display sheet 230 is made of a polycarbonate material , it has excellent strength, heat resistance, and impact resistance, so that scratches can be prevented even if frequent contact and friction by the driver occur, thereby preventing maintenance. This can save you money and time.

In addition, since the display sheet 230 has excellent transparency, the light emitted from the electroluminescent sheet 220 can be evenly diffused and visibility of figures and characters 233 can be improved.

In addition, an adhesive sheet (not shown) is formed on the rear surface of the display sheet 230 according to the present invention and is detachably coupled to the electroluminescent sheet 220 .

Therefore, when the figure or character 233 written on the display sheet 230 is changed, it is easily separated from the electroluminescent sheet 220 by pulling the display sheet 230, so replacement is easy. When changes are required, the entire control panel does not need to be disassembled or replaced.

That is, in the driver's control panel 200 according to the present invention, only the display sheet 230 needs to be replaced when the figure or character 233 is changed, and thus the base panel 110 does not need to be replaced.

Accordingly, the replacement cost of the base panel 110 is reduced, and since the manufacturing period of the base panel 110 is longer than that of the display sheet 230, the modification period is also shortened, thereby reducing costs.

The display sheet 230 configured as described above is brightly illuminated with light emitted from the electroluminescent sheet 220 by printing predetermined characters or figures or expressing desired characters, figures, or symbols using various color sheets. Light is transmitted so that figures and characters can be seen clearly.

The light sensor switch (Dimming Switch) 213c of the illuminance controller 213 is rotated in a clockwise direction, for example, to turn it on.

And, by rotating the light sensor switch 213c clockwise and counterclockwise, the current is controlled to adjust the intensity of the light to be strong or weak to suit one's own brightness.

By operating the light sensor switch 213c, DC 110V is applied from the railway vehicle, and after being converted to DC 12V by the DC/DC converter 213a and inverter 213b, the electronic light emitting sheet 220 of the control panel 200 power is applied to

That is, when the DC or AC voltage generated through the converter 213a and the inverter 213b is applied to the electrodes of the front electrode layer and the back electrode layer of the EL sheet 220, electrons in the fluorescent layer are excited and the excited electrons While being stabilized at a low energy level, light is emitted to the outside through the transparent front electrode layer.

Subsequently, the emitted light is emitted through each light projection part 223 formed around the rotary switch accommodating hole 221 and the push button accommodating hole 222 .

In addition, the light emitted through each of the light projection units 223 is evenly diffused and irradiated to the figures and characters 233 of the display sheet 230, so that each rotary switch 211 and push button 212 can be easily identified. make it possible

Accordingly, the rotary switch 211 and the push button 212 mounted on the driver's control panel 200 overcome the limited area of the irradiation area of the light irradiated by each rotary switch 211 and the push button 212, and the rotary switch 211 or push button located in a corner position Since bright light can be evenly irradiated even with the figures and letters 233 of 212, the driver can easily identify all figures and letters 233 even when outside light is not bright or when driving at night.

On the other hand, when the brightness of the external light is bright by the sun and the light of the electronic light emitting sheet 220 is not needed, the driver of the railway vehicle switches the optical sensor of the illuminance controller 213 mounted on the driver's control panel 200 ( Dimming Switch) 213c is rotated counterclockwise, for example, to turn OFF.

Therefore, the present invention enables the driver to adjust the brightness of figures and letters displayed on each rotary switch and push button formed on the control panel according to the driver's eyesight, thereby improving visibility during night driving and reducing the fatigue of each driver's eyes. In particular, it is possible to remarkably reduce eye fatigue of drivers who drive for a long time at night.

In addition, since the present invention can irradiate bright light regardless of the installation position of the rotary switch and the push button, it is possible to solve the conventional dark zone occurrence, thereby solving the limiting conditions such as selection of the installation position of the switch. can
