6360 results about "Power cord" patented technology

A power cord, line cord, or mains cable is an electrical cable that temporarily connects an appliance to the mains electricity supply via a wall socket or extension cord. The terms are generally used for cables using a power plug to connect to a single-phase alternating current power source at the local line voltage—(generally 100 to 240 volts, depending on the location). The terms power cable, mains lead, flex or kettle lead are also used. A lamp cord (also known as a zip cord) is a light-weight, ungrounded, single-insulated two-wire cord used for small loads such as a table or floor lamp.

High efficiency incandescent bulb replacement lamp

The invention discloses a high efficiency incandescent and Compact Fluorescent (CFL) bulb replacement LED lamp having a good color reproduction. The LED light bulb includes two groups of semiconductor light emitters and a luminescent material to emit four different spectrums of light. The two groups of semiconductor light emitters are enclosed around an interior wall of the light bulb housing, which has a plurality of fins at an exterior surface for effective heat dissipation. A high reflective member having a dome shape in the center is disposed under the two groups of semiconductor light emitters to redirect the emission and excitation lights from the two groups of semiconductor light emitters and recycle the backscattered light for multi-spectrum light mixing. The LED-light bulb further includes a single power line connecting to the two groups of semiconductor light emitters and a high efficiency electrical AC/DC conversion and control device. The light bulb has a diffuser dome for an output window and a conventional Edison-mount screw-type light bulb socket, a conventional fluorescent tube coupler arrangement or a conventional halogen MR-16 socket arrangement connecting to an AC power base. If a voltage is supplied to the AC/DC conversion and control device, a mixture light from the diffuser dome produces a warm white light with a color rendering index of at least 85 and a luminous efficacy of at least 80 lumens per watt.

High-efficiency multifunctional modular interior air purification device

The invention relates to a high-efficiency multifunctional modular interior air purification device. A device main body is cylindrical and consists of three cylindrical function modules which are combined and include a main l function module, a power control module and an additional function module from bottom top. The main function module with 360-degree omnibearing intake air design consists of a protective hood, a free rotating guide plate, a washable prefiltering glass fiber layer, an attached active carbon adsorption layer, an attached nano active carbon adsorption layer, a high-efficient PTFE filter layer, a load nano TiO2 porous ceramic sequentially from bottom top, as well as a UV lamp in the middle from the outside to the inside; the power control module consists of a power cord, a multifunctional power jack, a fan and a control panel; and the additional function module consists of a cylindrical guide plate, a guide protective hood and a solid essential oil dispersion box/negative ion generator/humidifier and the like. The high-efficiency multifunctional modular interior air purification device is compact in design structure, has no noise pollution, low energy consumption and an obvious purification effect, and is suitable for use in various interior places.
