A device for increasing energy at acupuncture points includes a housing, a light-emitting module, a base, a circuit device, a bending tube and a connection unit. The light-emitting module is disposed in the housing and has a plurality of light-emitting units. The base is a hollow casing. The circuit device includes a circuit board disposed in the base and electrically connected to a first connector. One end of the bending tube is connected to the housing. A transmission line is disposed in the bending tube. One end of the transmission line is electrically connected to the light-emitting module. The other end of the bending tube has a second connector electrically connected to the other end of the transmission line. The other end of the bending tube is removably connected to the base through the connection unit. The first connector and the second connector are selectively electrically connected.
