The tube-type LED illumination lamp includes at least one printed circuit board on which at least one LED is placed, and a heat dissipation cover that has at least one seating surface on which the printed circuit board is mounted. The seating surface is obliquely formed such that each printed circuit board is mounted on each inclined surface. According to the present invention, since a light diffusion angle is increased by obliquely positioning the printed circuit board on which the LED is placed, illuminance quality of the tube-type LED illumination lamp can be improved. | 09-11-2014 |
