PROBLEM TO BE SOLVED: To provide an LED road lamp which prevents occurrence of an accident such as incorrect wiring or contact and makes an exchange work of a power-supply unit easy by simplifying wiring in a connection box.SOLUTION: A road lamp 1 comprises: a connection box 30 in which voltage from a distribution network 40A is supplied to upstream, and terminal block units (30A, 30B) are built in; a first line 15 output from downstream of the connection box 30; a power-supply unit 31 in which the first line 15 is input to upstream, and which converts the voltage supplied through the first line 15 to required current-voltage form, and outputs it from downstream; multiple second lines 17 output from downstream of the power-supply unit 31; multiple third lines 5 connected to a light emitting unit 21; and a joint connector 7 which can connect/release the multiple second lines 17 and the multiple third lines 5 at a time. The joint connector 7 is arranged outside of the connection box 30. |
