The present invention relates to an LED lighting module including a reflection board and a lens. The LED lighting module includes: a PCB (10) on which LEDs (20) are mounted in a plurality of cavities (11) formed at predefined intervals in a predefined arrangement; the LEDs (20) each of which is mounted in each of the cavities (11) of the PCB (10), and radiates light directly; a reflection board (30) placed on the bottom surface except for the cavities (11) formed on the PCB (10), and reflects a portion scattered to the outside of the light emitted directly from the LEDs (20); and a diffusion lens (40) installed to surround the LEDs (20) mounted in the cavities on one end and the other end of the PCB (10) and the reflection board (30), and expands the radiation angle of the LEDs (20). According to the present invention described above, by attaching the diffusion lens to expand the angle of beam spread to both end lines of the cavities of a reflection panel, it is possible to secure linearity, overcome low uniformity of an LED, achieve high uniformity while using an appropriate amount of LED light devices, minimize blinding due to high brightness, and a brightness difference between a part where the LED chips are located and other parts even if a direct LED lighting device is manufactured to be slim (35 mm) as existing fluorescent lights. As a result, the dot phenomenon can be suppressed while not increasing the number of LED chips mounted on the PCB. |
