  • Patent number: 11844158
    Abstract: A single channel-based multi-functional light emitting diode lamp driving system includes: first and second light source groups distinguished for each lamp function thereof; a single LED lamp driving module adjusting an input voltage to a voltage required for each lamp function and to apply it to the first and second light source groups; a switching module controlling on or off of the first and second light source groups; and a control module controlling light amounts of the first and second light source groups by performing time-division control on an on or off time of the switching module in conjunction with the LED lamp driving module, wherein the control module is configured to perform time division turn-on control on the first and second light source groups by controlling at least one of a current value applied to the first and second light source groups or a duty ratio thereof in a high-beam passing mode.

  • Publication number: 20220235550
    Abstract: A rebar movement-prevention-type one-touch coupler is configured to allow rebars to be fixed without a movement of the rebars after performing a one-touch insertion. A fixation of the rebars is completed by performing an additional tightening operation to housing units into which the rebars are inserted. The coupler increases both the fixation stability of the rebar and the safety of a structure employing the rebar.
