Disclosed is an auxiliary brake lamp which comprises: a red LED unit located on one end or both ends in a longitudinal direction of the auxiliary brake lamp; and a light guide unit coming in contact with the red LED unit and guiding the light along the auxiliary brake lamp. The red LED unit includes: a blue LED device; and a red fluorescent body spread on the blue LED device and excited on the blue light of the blue LED device, and emitting red light. The auxiliary brake lamp blinks in accordance with the vehicle driver's braking motion. Through the auxiliary brake lamp, a certain level or higher output can be shown through the combination of shape patterns of the light guide unit just by using one or two blue LED devices with better output characteristics than those of a light LED device. In addition, thanks to the light concentration pattern formed on the surface of the light guide unit coming in contact with the red LED unit, light can be evenly guided even if light is transmitted far away along the light guide unit.

    본 발명은 보조 제동등 길이 방향의 일단 또는 양단에 위치한 적색 LED부; 및 상기 적색 LED부와 맞닿아 광을 상기 보조 제동등을 따라서 가이드하는 광 가이드부;를 포함하고, 상기 적색 LED부는, 청색 LED 소자; 및 상기 청색 LED 소자 상에 도포되어, 상기 청색 LED 소자의 청색광에 여기되어 적색광을 발광하는 적색 형광체;로 이루어지고, 차량 운전자의 브레이크 동작에 따라서 점멸하는 보조 제동등을 개시한다. 상술한 보조 제동등을 통해서, 적색 LED 소자보다 출력 특성이 좋은 청색 LED 소자 1-2개만으로도, 광 가이드부의 형상 패턴의 조합을 통해서 일정 수준 이상의 출력을 나타내고, 적색 LED부와 맞닿는 상기 광 가이드부의 표면에 집광 패턴이 형성되어 있어서, 광 가이드부를 따라서 멀리 광이 전달되더라도 균일하게 광이 가이드되게 한다.
