  • Publication number: 20080192461
    Abstract: The present invention discloses a portable worklight with two switchable lightsources, comprising a main body, a flexible compound cable, and a lampshade. The main body is disposed with a power supply unit to provide power to a main circuit board, which is coupled with the switch through power cords. The compound cable is connected to the top of the main body and the end of the lampshade, respectively, and is coupled with the switch and the first and second light source modules. The cable is coaxially disposed with a first and a second conductors, between which an inner insulated layer is provided; also, a third conductor is inserted into the inner insulated layer and an external insulated layer is wrapped over the second conductor. The inner chamber of the lamp holder of the lampshade is stackingly disposed with the first and second light source modules. Consequently, the switch may be used to selectingly turn on/off the first light source module or the second light source module.
