A durable pivotal connecting device for a table lamp between a base and a supporting post of the lamp having a lampshade and a lamp pipe, the supporting post is connected to a rotation seat located in the base and is pivotably assembled with the durable pivotal connecting device for rotation adjustment of the supporting post; the connecting device includes two sets of curved spring leaves, two connecting rods, a transverse bar and an adjusting bolt. The spring leaves are arciform and symmetrically arranged, and each includes a connecting end and is split to form a slit, a positioning end and an adjustment end; screws are used to lock the connecting ends and the positioning ends of the spring leaves onto the inner wall of the base to pivotably mount the rotation seat; the adjustment ends are connected to the connecting rods and the transverse bar to make association of the two sets of spring leaves. The transverse bar has a guide hole allowing passing through of the stem of the adjusting bolt from outside of the base, in order that the transverse bar is moved up and down by adjustment of the adjusting bolt; the adjustment ends of the spring leaves can be operated to give elastic binding action force on the rotation seat, and durability of the pivot area requiring frequent adjustment between the base and the supporting post can be assured.

An illumination device used in a compact disk receiving frame is disclosed. The illumination device includes a body. An electric wire is installed within the body. Another end of the electric wire is connected to a pressable switch. Each of two sides of the pressable switch is installed with a telescopic rod. A plate is installed between the two rod bodies. The plate serves, to prevent a short circuit due to contact of the two rod bodies. One end of each of die two rod bodies is connected to a lampshade. A bulb is installed in the lampshade. Thus, this illumination device is placed in the CD receiving frame to achieve the effect of illumination. Moreover, the user may read the data in the compact disks within the CD receiving frame conveniently.

A lighting device convertible between reading light and pen light configurations uses only a single off/on light actuating switch in either configuration. The lighting device includes a main body, pivoting arm, hinge, light generating element, batteries and switch member and button. The main body has opposite front and rear ends and defines a recess at the front end. The pivoting arm has opposite front and rear ends. The hinge pivotally mounts the rear end of the pivoting arm to the rear end of the main body to allow pivotal movement of the pivoting arm between an erect position angularly spaced from the main body, the reading light configuration, and a lowered position adjacent to the main body, the pen light configuration. The light generating element is mounted to the pivoting arm adjacent to the front end thereof for providing light therebelow when the pivoting arm is in the erect position and is insertable within the recess of the main body and exposed only at the front end of the main body to provide light directly forwardly of the main body when the pivoting arm is in the lowered position. The batteries are mounted within the main body and electrically interconnected to the light generating element and switch member. The switch member and button are mounted to the main body for switching the light generating element between off and on states.

A lighting device convertible between reading light and flashlight configurations has separate off/on light actuating switches. The lighting device includes a case, an elongated arm, hinge, light cap, light element, batteries, first switch and second switch. The hinge pivotally mounts a rear end of the arm to a rear end of the case to allow pivotal movement of the arm between an erect position angularly spaced from the case, the reading light configuration, and a lowered position against the main body, the flashlight configuration. The light element is mounted to the light cap which, in turn, is pivotally mounted to a front end of the arm for positioning the light element at various angles to provide light therebelow at various angles with the arm in the erect position and for positioning the light element at first and second angularly displaced positions to provide light directly forwardly of the case in the first position but not in the second position with the arm in the lowered position. The batteries are mounted within the case and are electrically connected to the light element and first and second switches. The first switch is mounted to the case and arm for switching the light element between off and on states in response to the arm being moved between the lowered and erect positions. The second switch is mounted to the case and arm for switching the light element between off and on states in response to the light cap being moved between the first and second positions with the arm in the lowered position.

A portable reading lamp of the invention comprises a base, a head portion and a pole to connect the base with the head portion. The head portion is provided with the luminant, which is semiconductor LED. A battery box is provided on the base, the head portion or the pole for supplying direct current. The semiconductor LED is used as the luminant in the invention, so the reading lamp of the invention can save energy in high-efficiency (10% electricity consumption of the traditional reading lamp), which also has the following strongpoint: saturated color and ray, infinite motley, switching rapidly, unpolluted, shock-resistant, dampness-resistant, long usage life (100,000 hours), radiation-free and less maintenance. The invention also provides a battery box in the base for supplying direct current, which is very convenient to be used in the field when no external power source can be used.
