Light-emitting diode (LED) light source module and LED light source thereof

The embodiment of the invention discloses a light-emitting diode (LED) light source module and an LED light source thereof. The LED light source comprises a single LED packaged lamp and a reflector. The single LED packaged lamp comprises a packaging bracket, and a luminous chip, fluorescent gel and a light distribution lens, which are arranged on the packaging bracket. A sidewall of the reflector is annularly arranged around the single LED packaged lamp. The bottom of the reflector and the single LED packaged lamp are fixed together. The C0-180 section and the C90-270 section of the reflector are overlapped with the C0-180 section and the C90-270 section of the light distribution lens respectively. The outlines of the C0-180 section and the C90-270 section of the reflector are symmetrical, and a vertex of the outline of the C0-180 section of the reflector is lower than that of the outline of the C90-270 section of the reflector. When the LED light source module and the LED light source are applied to tunnel illumination, the waste of light on the wall and at the top of a tunnel can be effectively reduced, and the utilization rate of luminous flux is increased; when the LED light source module and the LED light source thereof are applied to large-scale flood lighting, a gradual transition from a region below a lamp pole to the edge region of the lamp pole is realized, and remarkable dark regions and bright spots in an illumination region are avoided; and the process is simple and low in cost.
