Abstract:
An LED (Light-Emitting Diode) lighting bulb includes an electrical connector, a base, a circuit board, and a cover. The electrical connector is recessed to form a hollow configuration having an intermediate section forming threading. The base is formed by molding a moldable material.The base has a lower end forming a neck portion that has an outer circumferential surface forming threading for being fit to the electrical connector and an upper end to which the circuit board is mounted. The circuit board carries an LED thereon. The cover is formed by molding a moldable material and is mounted to the base. As such, an LED lighting bulb showing the advantages of reduced weight, reduced power consumption, improved heat dissipation performance, multiple colors, and excellent operation safety is provided.
Abstract:
A structure of holder of LED lighting tube includes a holder body, two end sockets, and two retainers. The two end sockets are respectively mounted to two ends of the holder body and each of the end sockets forms an opening. The two retainers are respectively received in the end sockets, and each of the retainers has a central portion forming a longitudinal passage, which receives and retains therein a metal clip. As such, the arrangement of power supply inside the holder body is simplified, so that the holder body and the end sockets can be manufactured in an integrally-formed manner and the metal clips can be used to clamp an LED lighting tube to thereby improving manufacturing efficiency and reducing manufacturing costs, and facilitating easy mounting and dismounting of the LED lighting tube.
Abstract:
A capacitor that has the features of heat dissipation and energy conservation comprises a capacitor core, an aluminum shell surrounding the capacitor core, the aluminum shell is covered with rubber that completely covers the top of the capacitor core, then with the use of an extruding machine, the upper orifice of the aluminum shell is extruded and sealed up around the rubber completely; the outer surface of the aluminum is formed with an aluminum oxidized insulating layer after the aluminum shell is processed through an aluminum metal surface transformation treatment, since the aluminum shell is not covered with plastic film (or sleeve), heat dissipation is enhanced; in addition, since plastic film or sleeve is not used, no pollution is occurred, and hence more friendly to the environment; furthermore, since heat generation is low, energy is conserved.
