Conventional light emitting type signs use a ramp type LED having a small divergence angle according to the optical transmission characteristics of the optical fiber.

In this case, when a plurality of LEDs are fabricated as a module and introduced into an optical fiber, there is little light superposition, resulting in a large gradient of light, and typically exhibits an uneven luminance distribution with a maximum minimum luminance ratio of about 3: 1.

On the other hand, in the present invention, by using a chip LED having a divergence angle larger than that of the ramp type LED, light overlap can be increased, and a brightness increasing effect can be obtained with a luminance ratio of 1.5: 1 as a whole.

The LED 510 controlled by the LED module 313 will be described later in detail.

The control unit 310 may further include a remote module 314 and a notification unit 315.

The power supply unit 311 may be interlocked with the plurality of batteries 20 and the battery 20 may be charged by the solar panel and the power supply unit 311 may be activated by the charged battery 20.

That is, the control unit 310 may include a solar module 312 interlocked with the solar panel 110. The solar module 312 converts light obtained from the solar panel 110 into electricity, And the LED module 313 can be driven through the battery 20 interlocked with the power supply unit 311. [

Referring to FIG. 4, the arrangement of the batteries 20 will be described. The batteries 20 may be arranged in a serial-parallel 3x4 arrangement.

Here, unlike the conventional serial-parallel 4x3 arrangement in which the battery 20 can be charged when the electricity generated by the sunlight is 14V, the battery 20 can be charged at 12V, and the power consumption is remarkably attenuated .

Also, it is preferable that the battery 20 is provided as a lithium iron phosphate battery whose arrangement can be adjusted flexibly.

The lithium iron phosphate battery can be fabricated in a straight or parallel structure that is flexible to about 2V different from the lead-acid battery and can be provided with a structure that maximizes the available current value by lowering the reference voltage to about 10V. May be provided as a lithium iron phosphate battery.

In addition, the rated voltage of the LED 510 used in the light emitting type signboard of the present invention is RED / YELLOW 2.2 V, WHITE 3.3 V, and the RED / YELLOW 5 bundle and the WHITE 3 bundle are connected in series and the remaining LEDs 510 may be configured to use a resistor or a driver IC so that the 12V voltage applied from the battery 20 can be set to a voltage of 10.8V using a lithium iron phosphate battery to attenuate the occurrence of power loss.

(Comparison of charged amount by solar module and battery arrangement on a clear day) Division (hour) Lead-acid battery (mA) Lithium Phosphate Batteries (mA) Efficiency Growth Rate (%) 14:00
(Lots of sunshine) 988mA 1062mA 7.5% 19: 00
(Small amount of sunshine) 15mA 28mA 86%

(Comparison of charged amount by solar module and battery arrangement on cloudy day) Division (hour) Lead-acid battery (mA) Lithium Phosphate Batteries (mA) Efficiency Growth Rate (%) 10:00 85mA 100mA 17.6%

In Table 1 and Table 2, the charging efficiency may vary depending on the solar module and battery arrangement.

Further, by using a lithium iron phosphate battery as a battery, it is shown that the charging efficiency is maximized as compared with the use of a lead-acid battery.

In addition, the solar module and the battery arrangement maximize the charging efficiency even on a cloudy day, thereby increasing the life of the battery. Thus, it is possible to efficiently charge the solar module utilizing the amount of sunshine received on the cloudy day.

The LED module 313 can be controlled by the power supply unit 311 to drive the LED 510 by receiving power.

The LED module 313 includes at least two LED modules 313 in the panel 130. The 2n-1th LED module 313 and the 2nth LED module 313 are intersected by the control unit 310, . ≪ / RTI >

Referring to FIG. 5 (b), the tapered shape of the light transmission tube 500 is for guiding the reflected light to a point (point b) having the most suitable optical efficiency that the driver can see, 50 to 1/100.

Referring to FIG. 6 (a) showing the front face of the optical fiber of FIG. 6 showing the optical fiber processing mode and FIG. 6 (b) showing a plan view of the optical fiber 530, And the tip is polished to have a trapezoidal shape when viewed from the front side, the rear side, and both sides, a value of? Is formed in a range of 28 to 30 degrees, D2 is in a range of 0.5 to 0.75 mm, .

Table 3 shows comparison with Comparative Example 1 (optical fiber cross section vertical cutting), Comparative Example 2 (optical fiber cross section sphere processing) and Embodiment 1 (optical fiber processing of the present invention) described above. , The luminance values are shown as the maximum and minimum ranges at the viewing angle (0) of 0 ° and the luminance values at the horizontal angle (θ) ± 30 ° and the vertical angle (θ) -20 ° are measured.

When the viewing angle is ± 30 degrees, the luminance value is the viewing angle when the vehicle is driven by the sign installed on the fixed stock holder, and the luminance value at the vertical angle of -20 degrees is .

Therefore, it can be understood that Embodiment 1 (processing of the optical fiber of the present invention) as shown in Table 2 is fabricated in such a form that the maximum viewing angle is obtained and the maximum luminance is exhibited within a viewing angle of 28 to 30 degrees.

In addition, the control box 300 provided with the control unit 310 is provided at one side of the column to be always exposed to theft. Therefore, a configuration capable of preventing the theft is needed.

3, the control unit 310 may further include a remote module 314 and a notification unit 315. [

The remote module 314 controls the controller 300 by receiving a signal to open and close the controller 300 wirelessly controlled by the manager of the light emitting type indicator through the wireless device.

That is, when one of the signal of the open / closed signal is received in the remote module 314, the control box 300 can be opened or closed.

However, if the remote module 314 is forced to open without receiving the open signal, it is sensed by a proximity sensor or a touch sensor mounted inside the control box 300 and a signal is transmitted to the notification unit 315 The received notification unit 315 transmits a signal to the speaker 120 provided in the body 100 to generate an alarm sound to the outside, thereby preventing the theft.

Accordingly, the role of the remote module 314 is used for the purpose of not only controlling the opening / closing of the control box 300 but also preventing the theft by a signal received wirelessly.

In addition, the controller 300 may further include a heat sensor 140 on the rear surface or one side surface of the control box 300 for the purpose of theft prevention.

The thermal sensor 140 is for theft prevention and can transmit the sensed value to the notification unit 315 and can be used as an auxiliary means for the purpose of theft prevention.

The heat sensor 140 generally detects heat, thereby preventing the heat from being detected at a certain distance.

A light emitting type signpost located mainly on a highway or at a speed of 80 km / h or higher may be a person or an animal approaching within one meter of the heat sensing range.

That is, it is assumed that the sensed value is not transmitted to the notification unit 315 by sensing the heat of the automobile.

Although the pillar 200 can be coupled to the lower portion of the body 100 and the pillar 200 is shown in FIG. 1 as being provided as a side stock (hanging or knotting) on the road, And a shape suitable for supporting the body 100 is sufficient. Therefore, the shape is not limited.

That is, since the shape of the sign post varies, the column 200 can be provided.

In addition, the column 200 may include a control box 300 on one side thereof.

Therefore, the column 200 may further include a power line for electrically connecting the control box 300 and the inside of the body 100, and a hole through which the power line can pass may be formed.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, You will understand. The embodiments described above are therefore to be considered in all respects as illustrative and not restrictive.
