20130134875 | Light Regulatable Led Illumination Lamp - A dimming LED lamp having an LED light, an EMI circuit, a power-factor correction circuit, a digital switching power supply circuit, a dimming control circuit, a power supply circuit, a signal acquisition circuit, an MCU microcontroller, a RF wireless transmitter, a RF receiver circuit, an EEPROM memorizer, and a fan circuit. The brightness of the dimmable LED lamp can be dimmed through any conventional incandescent dimmers, or through any ordinary key switch, or through a wireless transmitter. The wireless transmitter can also remotely turn on the lamps or turn off the lamps, at the same time the LED lamp also has the function of brightness saving. The fan circuit uses air convection to cool the LED which has the advantages of aesthetically pleasing appearance, small size, light weight, low cost, long life, and good cooling effect. | 05-30-2013 |
20110121955 | Energy-saving Control Circuit - This invention related to a kind of energy-saving control circuit connected between the electrical appliance and commercial power for turning on and off the power supply of the electrical appliances, said energy-saving control circuit comprises a relay control circuit for connecting and disconnecting the power supply of the electrical appliance; a main control module; a power conversion module; a circuit for collecting working current signals; said energy-saving control circuit further features: comprising at least a remote induction circuit at least provided with features of induction and receiving of remote signals, said remote induction circuit is connected to the main control module, said main control module, after said remote induction circuit received remote signals, will export control signals to the relay control circuit for connecting the power supply of the electrical appliance. Compared with existing technologies, the user only needs to approach the external micro induction transmitter for human body to “arouse” the energy-saving control circuit, and then the this electrical appliance can be turned on, which complies with the habit of most users. | 05-26-2011 |
