A pipe inspection device includes a housing ( 1 ) fixed to a semi-rigid rod ( 2 ) and having a longitudinal axis ( 3 ) and inside the housing a camera ( 4 ) having a forward-looking field of view and a camera ( 5 ) rotatable around said longitudinal axis ( 3 ) and having a field of view directed to permit closer inspection of an inner surface of the pipe, and means ( 17 - 24 ) for rotating the rotatable camera ( 5 ) to direct its field of view against an area of the inner surface of the pipe to be inspected more closely. To make it possible to inspect the inner surface of a pipe faster than with prior art devices, the inspection device has at least two cameras ( 5 - 7 ) in addition to the camera ( 4 ) having a forward-looking field. Said at least two cameras ( 5 - 7 ) are rotatable as an assembly around the longitudinal axis and have a field of view directed to permit closer inspection of an inner surface of the pipe. Further, the housing ( 1 ) has a fixed rear part ( 10 ) and a front part ( 11 ) that is carried by the rear part ( 10 ) and rotatable around said longitudinal axis ( 3 ), all of the cameras ( 4 - 7 ) being fixed in the rotatable front part ( 11 ) of the housing ( 1 ).

A LED package structure includes a substrate unit, a light-emitting unit, a support unit, a lens unit, an input unit and a control unit. The light-emitting unit includes at least one light-emitting element electrically connected to the substrate unit. The support unit includes a support element disposed on the substrate unit and surrounding the light-emitting element. The lens unit includes an electrically-controlled zoom lens disposed above the light-emitting element and retained by the support element. The input unit includes a signal input module for providing a predetermined voltage signal. The control unit includes a voltage controlling module electrically connected between the electrically-controlled zoom lens and the signal input module. Therefore, the voltage controlling module provides a predetermined voltage value for the electrically-controlled zoom lens according to the predetermined voltage signal, and the variable focal length of the electrically-controlled zoom lens is adjusted according to the predetermined voltage value.
