That is, the energy-saving pedestrian crossing LED lighting device of the present invention is designed to have a time (Tr + Tc1) that the eyes adapt to, because the phenomenon is not visible because it suddenly lights up when the LED lighting lamp 100 is turned on, and the time zone The maximum power is adjusted according to the power saving.

예컨대, 계절이나 시간대에 따라 조명등의 점등시간이나 조도를 제어할 수 있는데, 본 발명의 실시예에서는 다음 표1과 같이 시간대에 따라 3가지 모드로 구분하여 동작한다.For example, it is possible to control the lighting time or illuminance of the lamp according to the season or time zone, in the embodiment of the present invention operates in three modes according to the time zone as shown in Table 1 below.

표 1을 참조하면, 본 발명에 따른 절전형 횡단보도용 LED 조명장치의 동작시간을 일몰시간~ PM 12시까지와 PM12:00~AM05:00, AM05:00~일출시간으로 구분하여 보행자가 많은 시간대에서는 보행자의 안전을 위하여 광출력을 100% 점등하고, 보행자가 드문 밤12시부터 다음날 아침 5시까지는 전기 에너지 절약을 위하여 광출력을 60% 점등한다. 이때 일몰시간이나 일출시간은 계절에 따라 달라질 수 있으므로 조도센서(222)를 이용하여 판별할 수 있다.Referring to Table 1, the operation time of the power-saving pedestrian crossing LED lighting device according to the present invention is divided into sunset time ~ PM 12:00 and PM12: 00 ~ AM05: 00, AM05: 00 ~ sunrise time time zones with many pedestrians 100% light is turned on for the safety of pedestrians and 60% light is turned on to save electrical energy from 12 pm until 5 am the next day. At this time, the sunset time or sunrise time may vary depending on the season, and thus may be determined using the illumination sensor 222.

또한 광출력을 100%로 점등할 경우에는 도 6에 도시된 바와 같이, Tr시간동안 광출력을 70%로 상승시킨 후 Tc1시간동안 광출력을 100%로 증가시켜 눈이 적응할 수 있도록 하여 눈부심을 방지하고, Tc2시간 동안 점등한 후 소등시에는 Tf시간동안 광출력을 30%로 점차 하강하다가 완전 소등하여 눈이 적응할 수 있도록 한다.In addition, when the light output is turned on at 100%, as shown in FIG. 6, the light output is increased to 70% during the Tr time, and then the light output is increased to 100% during the Tc1 time so that the eyes can adapt to the glare. When the lamp is turned on for Tc2 hours and then turned off, the light output gradually decreases to 30% during the Tf time and then completely turns off so that the eyes can adapt.

그리고 광출력을 60%로 점등할 경우에는 도 7에 도시된 바와 같이, Tr시간동안 광출력을 60%로 상승시킨 후 Tc2시간 동안 점등을 유지하고 소등시에는 Tf시간동안 광출력을 30%로 점차 하강하다가 완전소등하여 눈이 적응할 수 있도록 한다.When the light output is turned on at 60%, as shown in FIG. 7, the light output is increased to 60% during the Tr time, and then the light is maintained for Tc 2 hours, and when turned off, the light output is 30% during the Tf time. It gradually descends and then completely extinguishes to allow the eye to adapt.

도 5를 참조하면, 보행녹색신호등이 감지되면, GPS의 시간정보와 조도신호를 고려하여 현재 시간모드를 판별한다(S501,S502). 본 발명의 실시예에서는 앞서 설명한 표1과 같이 3가지 시간대로 구분하여 동작한다. Referring to FIG. 5, when a walking green signal is detected, the current time mode is determined in consideration of GPS time information and an illumination signal (S501 and S502). In the embodiment of the present invention, the operation is divided into three time zones as shown in Table 1 above.

제1 시간모드(SET Time Ⅰ)이면, 시작시간(Tr)을 0.2초로 하여 PWM신호의 듀티를 0%에서 70%로 순차 증가시켜 광출력을 0에서 70%로 증가시키고, 온 타임(Tc1)시간을 0.5초로 하여 PWM신호의 듀티를 70%에서 100%로 순차 증가시켜 광출력을 70%에서 100%로 증가시킨다(S511~S513). 그리고 지속시간(Tc2)동안 듀티를 100%로 유지한 후 보행적색신호가 감지되면, 오프타임(Tf)을 3초로 하여 PWM신호의 듀티를 100%에서 30%로 순차 감소시켜 광출력을 100%에서 30%로 감소시킨 후 소등시킨다(S514~S516).In the first time mode (SET Time I), the duty time of the PWM signal is sequentially increased from 0% to 70% by setting the start time (Tr) to 0.2 seconds, thereby increasing the light output from 0 to 70%, and the on time (Tc1). The time is 0.5 seconds to sequentially increase the duty of the PWM signal from 70% to 100% to increase the light output from 70% to 100% (S511 to S513). If the walking red signal is detected after the duty is maintained at 100% for the duration Tc2, the duty cycle of the PWM signal is sequentially reduced from 100% to 30% with the off time Tf of 3 seconds, thereby reducing the light output by 100%. After reducing to 30% in the off (S514 ~ S516).

제2 시간모드(SET Time Ⅱ)이면, 시작시간(Tr)을 0.2초로 하여 PWM신호의 듀티를 0%에서 60%로 순차 증가시켜 광출력을 0에서 60%로 증가시키고, 지속시간(Tc2)동안 듀티를 60%로 유지한 후 보행적색신호가 감지되면, 오프타임(Tf)을 3초로 하여 PWM신호의 듀티를 60%에서 30%로 순차 감소시켜 광출력을 60%에서 30%로 감소시킨 후 소등시킨다(S521~S525).In the second time mode (SET Time II), the duty time of the PWM signal is sequentially increased from 0% to 60% by setting the start time (Tr) to 0.2 seconds, and the light output is increased from 0 to 60%, and the duration (Tc2) If the walking red signal is detected after maintaining the duty at 60%, the duty cycle of the PWM signal is sequentially reduced from 60% to 30% with the off time (Tf) of 3 seconds, thereby reducing the light output from 60% to 30%. After turned off (S521 ~ S525).

제3 시간모드(SET Time Ⅲ)이면, 시작시간(Tr)을 0.2초로 하여 PWM신호의 듀티를 0%에서 70%로 순차 증가시켜 광출력을 0에서 70%로 증가시키고, 온 타임(Tc1)시간을 0.5초로 하여 PWM신호의 듀티를 70%에서 100%로 순차 증가시켜 광출력을 70%에서 100%로 증가시킨다(S531~S533). 그리고 지속시간(Tc2)동안 듀티를 100%로 유지한 후 보행적색신호가 감지되면, 오프타임(Tf)을 3초로 하여 PWM신호의 듀티를 100%에서 30%로 순차 감소시켜 광출력을 100%에서 30%로 감소시킨 후 소등시킨다(S534~S536).In the third time mode (SET Time III), the duty time of the PWM signal is sequentially increased from 0% to 70% by setting the start time (Tr) to 0.2 seconds, thereby increasing the light output from 0 to 70%, and the on time (Tc1). The time is 0.5 seconds to sequentially increase the duty of the PWM signal from 70% to 100% to increase the light output from 70% to 100% (S531 to S533). If the walking red signal is detected after the duty is maintained at 100% for the duration Tc2, the duty cycle of the PWM signal is sequentially reduced from 100% to 30% with the off time Tf of 3 seconds, thereby reducing the light output by 100%. After reducing to 30% in turn off (S534 ~ S536).
