Abstract: The present invention provides a light-projector comprising a metal trunk, a tube face, a light emitting diode, a button, a set of batteries and a back cover, wherein the metal trunk is a hollow tube with a side through hole for locating a button, and an insulating core seat located into the inside of the metal trunk has two through-holes without connecting each other for plugging in the long and short base pins of the light emitting diode therein the long pin stretches out from the core seat, and the short pin is hidden into the core seat, and for exposing the short pin, the core seat is cut through a groove so that a triangular spring leaf can cover on opposite the button exactly. Due to adopting above-mentioned mechanism, in the present invention the light emitting diode just need to plug into the plastic core seat without welding on a PC board, so the production cost is reduced and the procedures are decreased too.
