Abstract: A night lamp includes a main body and a light distribution unit, which allows the passage of light and is fitted onto the main body. The thickness of the light distribution unit gradually increases from the bottom to the top. The light distribution unit has an arcuate front surface. A sunken design is provided in the front surface of the light distribution unit and the thickness of the sunken design gradually increases from the bottom to the top. A plurality of light refractive pieces are provided on the front surface and periphery of the sunken design. When light is generated by the light generating units, light may be evenly distributed in the light distribution unit and hence the light distribution unit may deliver evenly distributed light so that light may reach a broader range.

Abstract: A power strip includes a primary distribution unit, a secondary distribution unit, a primary power cord, at least two secondary power cords and at least two third-level power cords. The primary distribution unit has three distribution points, and each of the three distribution points is in electrical communication with a respective line of the three lines (positive line, neutral line and ground line) of the primary power cord. An electrical plug is provided at the free end of the primary power cord, and each of the three lines of each secondary power cord is in electrical communication with a respective distribution point. Also, each secondary power cord is in electrical communication with at least two third-level power cords. Hence, electricity may be fed from the electrical plug to the primary power cord, secondary power cords and third-level power cords and then to the sockets.

Abstract: An overload warning device is used for electric sockets. The overload warning device of the present invention is disposed in the sockets of an extension cord or the sockets fixedly fitted in a wall. When there is an overload, the overload warning device will send out a warning sound and/or warning light so as to tell a user to unplug one or more electric plugs from the sockets so that safety may be assured.

Abstract: An electronic stabilizer used for hand-held lamp is disclosed. The electronic stabilizer of the present invention comprises four circuits: a current overflow protection and current source noise absorption circuit, a voltage-enhancing rectification filtering circuit, a high-frequency oscillation circuit and a harmonic oscillation output circuit. The current overflow protection and current source noise absorption circuit can protect against current overflow and current source noises. The voltage-enhancing rectification filtering circuit may covert the AC to DC after rectifying and filtering out the current. Next, the DC is fed to the high-frequency oscillation circuit, which may convert the DC to rectangular wave signals. Then, the harmonic oscillation output circuit converts these rectangular wave signals into sine wave (near sine wave) signals. Now, the sine wave signals may light up one or more fluorescent lights and may enable these fluorescent lights to give out continuous light without any flickers.

Abstract: A socket power supply control structure is controlled by a controller in three stages, e.g. “power on,” “power off”, and “power source disconnected”. By so, unauthorized use of outlet supplying power for working various electrical appliances such as television computer, and microwave oven, by innocent children can be effectively avoided so as to protect their health of eyes and electric safety.

Abstract: A winding reel includes a first and a second reel cover and a rotating ring. A hollow positioning shaft is extended in the center of the first reel cover. The positioning shaft is circumferentially provided with a flange. The flange is provided with at least one fastening notch. An inner and an outer ring body are extended in the center of the second reel cover. A pivoting notch is formed between the inner and the outer ring body. By connecting the first reel cover to the second reel cover, an elastic fastener provided on the outer ring body can be fastened to the fastening notch provided on the flange of the first reel cover. As a result, the user can simply hold the handle of the rotating ring to twirl the first reel cover and the second reel cover, and thus achieve the winding of the power supply line.

Abstract: An electric socket includes a rotation unit and a switching cap unit. The rotation unit abuts the conducting units inside the socket. The switching cap unit protrudes from the rest of the socket. The rotation unit may be moved along with the switching cap unit. When each of the two prongs of a plug is inserted into the two prong slots of the socket, a user may rotate switching cap unit by a certain angle so that the long sides of the rotation unit may press against the two conducting units of the socket; now, the two conducting units of the socket seize and lock the two prongs of the plug. To take out the plug, a user may rotate the switching cap unit in the reversed direction by a certain angle; now, the two long sides of the rotation unit no longer press against the two conducting units, and the plug may be taken out from the two slots.
