Abstract

A flashlight head connected electrically to a battery is positioned within a housing at a front end thereof and locked by a light-transmissible front cap. The flashlight head includes a project barrel and a control base. A reflector is disposed at a front end of the project barrel and a light source portion of the reflector is mounted on a positioner. An opening is disposed at a center of the positioner. A luminous body passes through the opening and extends into a center of the light source portion of the reflector. The luminous body has a positive electrode pin and a negative electrode pin, and each of the positive electrode pin and the negative electrode pin extends onto the positioner. A cooling plate is adhered to a back side of the luminous body. Two slots form on the cooling plate and are disposed corresponding to the positive electrode pin and the negative electrode pin. A switch is mounted on the control base and positioned corresponding to a button on the housing. A circuit board is mounted on one end of the control base and has a positive electrode conductor and a negative electrode conductor positioned corresponding to the positive electrode pin and the negative electrode pin of the luminous body respectively. The positive electrode conductor and the negative electrode conductor pass through the slots of the cooling plate and connect electrically to the positive electrode pin and the negative electrode pin of the luminous body respectively while the control base assembles with the project barrel. The luminous body is controlled by the circuit board and the switch. The luminous body is disposed in the center of the project barrel and the center of the light source portion of the reflector, i.e. the focus of the flashlight, so the flashlight is assembling without calibrating the focus. The efforts of assembling easily and quickly and high quality are reached.
