  • Patent number: 10845008
    Abstract: An LED filament comprises at least one LED section, a conductive section, two conductive electrodes and a light conversion layer. The conductive section is used to electrically connect two adjacent LED sections. The two conductive electrodes are electrically connected to each of the LED sections. Each of the LED sections includes at least two LED chips electrically connected to each other. The light conversion layer covers the LED sections, the conductive sections and the conductive electrodes, and a part of the two electrodes is exposed respectively. Since the LED filament includes the LED section and the conductive section, when the LED filament is bent, the stress is easily concentrated on the conductive section. Therefore, the breakage probability of the conductive wires connected within the LED section is reduced during bending. The quality of the LED filament and its application is improved.

    Abstract: A weighing sensor and a lever are disclosed. The weighing sensor has a load-receiving portion, a fixing portion, and a parallel guiding portion connected to the load-receiving portion and the fixing portion. The parallel guiding portion has upper and lower parallel guiding units, separated from each other. The ends of the parallel guiding units are connected to the load-receiving portion and the fixing portion. The fixing portion has an extension located between the parallel guiding units. The extension is at a distance from both parallel guiding units and extends to the load-receiving portion. A gap is formed between the extension and the load-receiving portion; and the distance between the extension and the upper parallel guiding unit allows a lever to pass through. The weighing sensor has a simple structure, both the processing process and the assembly process are simplified, and the processing and assembly during production are facilitated.

  • Patent number: 10833674
    Abstract: A switch device including a switch circuit and switch controller. The switch circuit comprises first and second switches to selectively enable a path between an input terminal and an output terminal. The switch controller refers to a selection signal and a switch signal to respectively generate a first switch control signal at a first switch control signal output terminal and a second switch control signal at a second switch control signal output terminal. When the voltage level of an input signal at the input terminal is larger than a power voltage, the switch controller generates the first switch control signal and the second switch control signal capable of turning off the switch circuit. When the voltage level of the input signal is not larger than the power voltage, the switch controller generates the first switch control signal and the second switch control signal according to the switch signal.
