  • Patent number: 10277221
    Abstract: A protection circuit includes a periodicity determination device, an off circuit and a control device. The periodicity determination device directly or indirectly detects a noise superimposed on a first transistor including a control terminal and determines periodicity of the noise. The off circuit is connected to the control terminal of the first transistor and is configured to perform an off-operation of the first transistor. The control device enables the off-operation of the first transistor, performed by the off circuit, when the periodicity determination device determines that the noise has periodicity. The control device disables the off-operation of the first transistor, performed by the off circuit, when the periodicity determination device determines that the noise does not have periodicity. Accordingly, the protection circuit withdraws an ESD energy while stabilizing a circuit operation.

    Abstract: The present application provides an electrical cigarette and a battery assembly thereof, wherein a first charging electrode assembly is arranged at a front end of the battery assembly, such that the battery assembly can be directly inserted into a charger to be charged without removing an atomizing assembly, therefore the operation is more convenient and disadvantages caused by frequent disassembling and assembling may be avoided. In addition, under the action of a charging management circuit, the electrode assembly at the front end can only be charged but cannot discharge, thereby avoiding an occurrence of a short circuit when the charging terminal discharges, extending the service life of the battery, and further avoiding a hidden danger of battery liquid leakage caused by the short circuit. In addition, since the front end of the electronic cigarette can not discharge, a situation that the electronic cigarette still has a low battery even been charged for a long time will not happen.

  • Patent number: 8970125
    Abstract: In a memory unit 6, there is stored a correction table for each candidate value of an output set value of each of LED units 2. If UV rays have ever been emitted so far by the LED units 2, each of which is formed of a plurality of LED chips 8, then a PLC 5 acquires, upon setting of a output set value by an operation unit 53, a correction value corresponding to a cumulative emission time up to a previous emission, from the correction table of the output set value. Thereafter, the PLC 5 sets the magnitude of the power supplied to each of the LED units 2 using the acquired correction value. If an output set value different from a previous output set value is set, the PLC 5 obtains the correction value starting from the cumulative emission time upon modification. As a result, the UV irradiation apparatus enables power consumption necessary for emission of UV rays to be reduced, and UV ray output to be kept constant regardless of the cumulative emission time, even if the output set value is modified.

  • Patent number: 8941312
    Abstract: An enhanced control mechanism for an LED light string system is provided for switching between one of two DC output phases or polarities so as to actuate one or the other of two LEDs within the bulbs on the light string. The control mechanism is further configured to allow switching so as to pass through the input power provided by a high-to-low voltage converter that is plugged into its electrical power feeding end. The control mechanism may then provide rectified AC voltage, or DC voltage, of various switched values to the LED string according to the particular needs of the LED bulbs.

  • Patent number: 8933649
    Abstract: An example power converter includes a first winding, a second winding, a switch, a controller and an output circuit. The second winding is magnetically coupled to the first winding and the controller includes a feedback terminal and a common terminal. The controller is coupled to control the switch to regulate an output of the power converter in response to a feedback voltage received at the feedback terminal. The output circuit is coupled between the common terminal of the controller and a common reference of the power converter to provide an output voltage to a load. The feedback voltage is a positive voltage with respect to the common terminal and the output voltage is a negative voltage with respect to the common reference of the power converter.

  • Patent number: 8907572
    Abstract: An LED based lighting system for use in highway lighting, adaptations to current highway lighting systems, and associated methodology. The highway lighting system can be implemented in new highway installations and also by retrofitting existing highway installations. Unlike highway lighting systems in the prior art that convert AC to DC and clean the harmonics at each lamp post, the lighting system converts AC to (high voltage) DC and cleans the created harmonics at a centralized location thereby supplying high voltage DC to each lamp. The high voltage DC is then stepped down at each lamp post via communicating with centralized command center. This allows each lamp to be dimmed from full brightness to 0% brightness and also to be dimmed independent of one another (which in turn allows for automatic checking whether each lamp is functioning properly).

    Abstract: A lighting system as disclosed herein may include a lighting device, a switch to control the lighting device, and a controller to assign an address to the lighting device and the switch. The controller may be connected to the lighting device and the switch over a ZigBee network. The lighting device and the switch may have a first address and a first network identifier. The lighting device or the switch transmits a request for address assignment to the controller based on the first address, the request including the first network identifier, and the controller compares the first network identifier to a second network identifier stored at the controller, and may assign a second address based on the request if the first network identifier is the same as the second network identifier.

The light source is mounted on the same substrate or chip board so that the LEEs are in thermal contact with each other such as to enable thermic conduction and heat transfer between the LEEs. The system is switchable between light source modes in which different light emitting elements or a different number of light emitting elements is switched in an on mode and in a down mode respectively. In all light source modes, one or more light emitting elements, such as those with longer expected lifetime, remain in the on mode, while one or more light emitting elements, such as those with shorter expected lifetime, may be switched in the down mode.
