FLUORESCENT LAMP TYPE SEMICONDUCTOR LAMP AND SLEEVE PARTS OF THE SAME

PROBLEM TO BE SOLVED: To provide a fluorescent lamp type semiconductor lamp which can easily change irradiation direction while being attached to lighting equipment as it is and, further, can adjust fastening force in the irradiation direction.SOLUTION: In a fluorescent lamp type semiconductor lamp, a light-emitting tube part 1 inserted between sleeve parts 2, 2 is made swingable around a center axial line, is locked at a prescribed angular position to exhibit a fastening force, the locking is released by applying a torque in the swinging direction to the light-emitting part 1 and, therefore, the irradiation direction can be changed in the attachment state. Therein, the sleeve parts 2, 2 a stationary side member 3 of which one edge side is fastened to the light-emitting part 1 and a movable member 4 which is pivotally supported to the other edge side and is made swingable. Further, a protrusion part 45 disposed on one side of opposed surfaces with which the stationary member 3 and the movable member 4 are brought into sliding contact and a recessed part 300 disposed on the other side thereof are pressed in an adhesion direction on the locking position and, thereby, a fastening force is exhibited. As the result, by performing swinging operation of a gear 37, a pressing force of the spring member 34 is changed and the fastening force is adjusted.
