An embodiment relates to an optical module which comprises: a light transmitting unit for emitting a plurality of beams to a scanning area so as to scan the scanning area; and a light receiving unit for measuring information on an object located inside the scanning area, using backward light which is reflected and returned from the object after the emitted beams hit the object, wherein the scanning area includes at least one scanning area, and the light transmitting unit scans the at least one scanning area at at least one scanning rate.

Optical output module, vehicle including same, and control method therefor

An embodiment relates to an automatic water supply device comprising: a container seating portion, one side of which is open such that a container is placed; a water intake member arranged on the upper portion of the container seating portion so as to supply the container with a liquid; a container height measuring unit and a water level measuring unit arranged to be adjacent to the water intake member, respectively; and a control unit for comparing the height of the container, which is measured by the container height measuring unit, and the water level, which is measuring by the water level measuring unit, thereby checking whether the water level inside the container reaches a preset height or not, and adjusting the water level inside the container using the result of the checking, wherein the container height measuring unit comprises a plurality of first optical sensors for sensing both ends of the upper end of the container, and can measure the height of the container in response to the result of sensing by the first optical sensors.

Automatic water supply device

A light emitting device package is disclosed. The light emitting device package includes a light source, a lens located on the light source, and a pattern unit located on the lens, wherein the lens includes a body having a first lower surface facing the light source and a protrusion protruding from the body in a direction other than a direction of optical axis, and the pattern unit is located on at least one selected from among at least a portion of a surface of the protrusion and a first side surface of the body.

Light emitting device package and backlight unit including the same

A dispenser for a refrigerator is provided which allows for more storage space inside the refrigerator, and which includes a locking mechanism which allows a drain pan of the dispenser to be removably attached. The dispenser includes a housing mounted on a front surface of a refrigerator door, a supply pipe installed at an upper portion of the housing, a drain pan detachably disposed at a lower portion of the housing, and a locking unit formed between the drain pan and the housing which removably attaches the drain pan to the dispenser housing. The locking unit prevents unwanted separation of the drain pan from the dispenser, and the dispenser's reduced size allows for more storage space in the refrigerator.
