A lighting unit (500) to be used for illumination includes an LED unit (40) having a semiconductor light emitting unit (44), a radiating board (42) for directly fixing the semiconductor light emitting unit (44) to an upper surface, and a contact (46) formed on the radiating board (42) and serving to input a power to cause the semiconductor light emitting unit (44) to emit a light, an attachment (16a) having a power supply portion (162) for surrounding and holding the LED unit (40) and supplying a power to cause the semiconductor light emitting unit (44) to emit a light from an external power plug to the contact (46) in a state in which at least a part of lower and side surfaces of the radiating board (52) and an upper part of the semiconductor light emitting unit (44) are open. |
