The LED light source substrate 6 and the LED cover 7 are fastened and fixed together through the holes for screws at symmetrical positions in the left-right and vertical directions about the through hole 5a.
Further, the reflector 5 has a trapezoidal convex portion toward the central portion, and by attaching the LED light source substrate 6 to the convex portion, the heat of the LED light source substrate 6 is radiated and cooled.

The LED light source substrate 6 has a plurality of LED elements in a plurality of rows on the circumference. The LED element has a daylight LED. The daylight LED is characterized by emitting daylight light having a peak wavelength of 430 to 460 nm. The LED element is not limited to this.
The LED light source board 6 is connected to the power supply board 4 by an electric wire, and dimming is performed by, for example, turning on, turning off, and adjusting the current value by controlling light emission from the pull switch 9 and the power supply board 4. The switching of the lighting state by the pull switch 9 is repeated in order.

The LED cover 7 has a circular plate surface, and has a plurality of convex portions having a lens function corresponding to the arrangement of the LED elements on the plate surface. Further, the side surface of the circular plate surface has a wall surface along the trapezoidal convex portion of the reflector 5, which plays a role of insulating from the LED light source substrate 6. Further, the LED cover 7 has a screw hole on the circumference located at the center of the outer diameter and the inner diameter of the plate surface portion, and is fastened and fixed to the reflector 5 together with the LED light source substrate 6 by screws.

The translucent cover 8 fits into the outer peripheral portion of the backbone 2 and is rotated in the radial direction so that the convex portion of the translucent cover 8 fits with the receiver (not shown) and is detachably attached. The translucent cover 8 has the effect of diffusing light, reducing glare, and spreading light evenly in the space.
