  • Patent number: 11396989
    Abstract: A lamp for a vehicle includes a light source unit, and a light guide lens unit disposed above the light source unit. The light guide lens unit is configured to allow a distance from a center of the light source unit to a peripheral end to be substantially constant. The light guide lens unit includes a reflection unit disposed at a central portion of one surface of the light guide lens unit for reflecting a light incident from the light source unit from a center of the light guide lens unit toward the peripheral end. Further, the reflection unit includes a diffusion lens unit for diffusing the light incident from the light source unit. Accordingly, a first part of the light incident to the light guide lens unit is reflected by the reflection unit, and a second part of the light incident to the light guide lens unit passes through the reflection unit and is incident to the diffusion lens unit.

  • Patent number: 10166912
    Abstract: An LED driving apparatus group in which first and second LED groups are connected in series is provided. The apparatus includes a voltage input unit that receives an input voltage from a vehicle power device and a current controller that generates a current with a predetermined level by adjusting the received input voltage and provides the current to an input terminal of the first LED group. A first feedback path feeds back a voltage applied to a first node, which is connected to an output terminal of the first LED group, to an input terminal of the current controller. A first switching unit is disposed on the first feedback path and is switched on or off based on a control signal. A second switching unit is disposed between an output terminal of the second LED group and ground and is switched on or off based on the control signal.
