The first reflector 303 and the second reflector 305 may reflect the LED light emitted from the LED substrate 40 and enhance the straightness of the LED light.

Conventional LED lighting has low linearity of LED light and low illumination efficiency of about 2100 lumens (Lm).

On the other hand, the LED illuminating lamp 100 can increase the straightness of the LED light by using the first reflector 303 and the second reflector 305 and obtain a high light amount of about 2,300 lumens (Lm). Therefore, it is possible to reduce the number of LEDs 401 mounted on the LED substrate 40 at the same power.

The seating portion 601 may include one side surface 6011 and the other side surface 6013. The one side surface 6011 and the other side surface 6013 can extend in a direction approaching each other. In this case, since the one side surface 6011 and the other side surface 6013 extend in a direction approaching each other and the width thereof is smaller than the width of the LED substrate 40, the LED substrate 40 positioned above the seating portion 601 Can be fixed.

The third reflector 603 may be connected to one side 6011 and the fourth reflector 605 may be connected to the other side 6013. The third reflection plate 603 and the fourth reflection plate 605 may extend in directions away from each other.
