Abstract: A lighting apparatus such as for a display apparatus equipped for an instrument panel of an automobile, for example, comprises a light source, such as a light-emitting diode, having polarities of substantially a tubular structure having a center axis, a circuit board arranged substantially on the center axis of the light source and electrically connected thereto, a socket body having substantially a cylindrical structure for accommodating the circuit board, and contact terminals accommodated in the socket body and including an inner terminal portion electrically connected to the circuit board through a contact point of the circuit board and an outer terminal portion electrically connected to the inner terminal portion and fixed to the socket body so as to protrude outward the socket body. The circuit board is provided with a flicker element for flickering the light source at 0.5 to 10 Hz controlled by a control unit provided for a printed circuit board of the display apparatus.

Abstract: A contact strip for use with lamp socket devices where an electrical connection is made by the contact strip between a lamp lead and a circuit board conducting surface when the contact strip is assembled in a lamp socket device and mounted on the circuit board. At least one welding area at which a lead of a lamp is welded during assembly of the contact strip in a lamp socket device is provided. The contact strip includes upper and lower electricity receiving strip portions for receiving a circuit board therebetween and for making electrical contact with at least one of upper and lower conducting surfaces of the circuit board.
