The present invention relates to a high condensing light emitting diode (LED) searchlight. The LED searchlight comprises: a multi-chip package (MCP) light source module emitting light to a rear side, and integrating multiple LED chips to irradiate high brightness light, and a hemispheric parabolic reflecting plate placed in the rear side of the MCP light source module to collect the light irradiated from the MCP light source module and irradiate the collected light to a front side. The light outputted from the MCP light source module is formed to be suitable for a horizontal distance (focal length) between the MCP light source module and the parabolic reflecting plate to efficiently concentrate the light outputted from the MCP light source module on the parabolic reflecting plate. The focal length (p) is calculated by a parabolic calculation formula, p = x^2/4y (p: a focal length, x: a radius (R) of a parabolic reflecting plate and y: the depth (H) of a parabolic reflecting plate). Suitably forming a horizontal distance (focal length) between the MCP light source module outputting the light to the rear side and the parabolic reflecting plate concentrating the light output from the MCP light source module to output the concentrated light through the parabolic calculation formula, the light outputted from the MCP light source module is efficiently concentrated and outputted through the parabolic reflecting plate, high brightness light is outputted from a small amount of light, so the size of the searchlight is minimized while reinforcing performance of the searchlight. 본 발명은 고집광 LED 탐조등에 관한 것으로, 그 구성은 후방으로 빛을 발광하는 것으로, 다수의 LED(Light emitting diode) 칩이 집적되어 고휘도 광원을 발산하는 MCP(Multi Chip Package) 광원모듈과, 상기 MCP 광원모듈의 후방에 위치되어 상기 MCP 광원모듈에서 발산되는 광원을 모아 전방으로 조사되도록 하는 반구형의 파라볼릭(Parabolic) 반사판을 포함하는 LED 탐조등에 있어서, 상기 MCP 광원모듈에서 출력되는 광원이 상기 파라볼릭 반사판에 효율적으로 집광될 수 있도록 상기 MCP 광원모듈과 상기 파라볼릭 반사판의 수평 이격된 거리(초점거리)를 적합하게 형성하되, 상기 초점거리(p)는 아래의 [수학식-Ⅰ]을 통해서 계산되는 것으로서, p = x/ 4y ..[수학식-Ⅰ] p : 초점거리 x : 파라볼릭 반사판의 반지름(R) y : 파라볼릭 반사판의 깊이(H) 후방으로 광원을 출력하는 MCP 광원모듈과 MCP 광원모듈에서 출력되는 광원을 집광하여 전방으로 출력하는 파라볼릭 반사판의 수평 이격 거리(초점거리)를 파라볼릭 계산식[수학식-Ⅰ]을 통해 적합하게 형성함으로, MCP 광원모듈에서 출력되는 광원을 파라볼릭 반사판을 통해 효율적으로 집광 출력하여 적은 광량으로 고광도의 광원을 출력할 수 있어 탐조등의 성능은 강화하되 크기를 최소화할 수 있는 효과가 있다.
