Disclosed is a traffic signal lamp apparatus capable of reducing the number of traffic signal lamps installed on a support pole by turning on or off an LED module using driving power of another SMPS when one SMPS is malfunctioning. According to an aspect of the present invention, the traffic signal lamp apparatus includes: a front cover (110) mounted in a signal lamp case (200) installed in a support pole (20) and formed at a center thereof with a light emitting hole (111) opened forward and rearward; a rear cover (120) mounted on a rear side of the front cover (110); an LED module (130), which is vertically disposed and includes a patterned PCB (131) and a plurality of LEDs (132) mounted on a front surface of the PCB (131), in which the LED module (130) is arranged between the front cover (110) and a rear cover (120) or inside the rear cover (120) to emit LED light through a light emitting hole (111) according to driving power applied thereto; a first SMPS (140) for supplying driving power to the LED module (130); and a second SMPS (150). A total light emitting area of the LED module (130) where the LEDs (132) are disposed is divided into a main light emitting area (R1), a first fault display area (R2) and a second fault display area (R3). The first SMPS (150) supplies driving power to the main light emitting area (R1) and the first fault display area (R2) and the second SMPS (150) supplies the driving power to the main light emitting area (R1) and the second fault display area (R3).
본 발명의 특징에 따르면, 지주(20)에 설치된 신호등케이스(200)에 장착되며 중앙에는 발광공(111)이 전후로 개구된 전면커버(110); 상기 전면커버(110)의 후방측에 장착되는 배면커버(120); 직립배치되고 회로라인이 패터닝된 PCB(131) 및 상기 PCB(131)의 전방면에 실장되는 다수의 LED(132)를 포함하며, 상기 전면커버(110)와 배면커버(120) 사이 또는 배면커버(120)의 내부에 배치되어 인가되는 구동전원에 따라 상기 발광공(111)을 통해 LED광을 발산하는 LED모듈(130); 및 상기 LED모듈(130)에 구동전원을 공급하는 제1SMPS(140); 및 제2SMPS(150);를 포함하되, 상기 LED모듈(130)은 각 LED(132)가 배치된 전체 발광영역이 메인발광영역(R1), 제1고장표시영역(R2) 및 제2고장표시영역(R3)으로 구분되고, 상기 제1SMPS(140)는 상기 메인발광영역(R1)과 제1고장표시영역(R2)에 각각 구동전원을 공급하며, 상기 제2SMPS(150)는 상기 메인발광영역(R1)과 제2고장표시영역(R3)에 각각 구동전원을 공급하는 것을 특징으로 하는 교통신호등 장치가 제공된다.
