Lamp for vehicle
11988354 · 2024-05-21 · ·

A lamp for a vehicle forms a rear road surface pattern when the vehicle moves backward. The lamp for the vehicle includes a light source unit configured to generate light, a shield unit configured to selectively transmit a portion of the light generated from the light source unit, and a lens unit configured to concentrate the light transmitted through the shield unit onto a road surface. The lens unit includes a first lens part and a second lens part, and the second lens part includes an inner space through which the light emitted from the light source unit is transmitted.

Vehicle lighting with redundant control

A lighting system of a vehicle may include light units and controllers for operating the light units. Each light unit is multifunctional in that the light unit may operate in various modes, which may be invoked at different times under varying circumstances. A light unit on the first end of a vehicle may operate as a headlight if the first end is the front end of the vehicle. On the other hand, the light unit may operate as a tail light if the first end is the rear end of the vehicle. Furthermore, the light unit may operate as a turn signal in either direction or brake light while the first end is the rear end of the vehicle. The light unit includes a lens array positioned to receive light from various light sources. The lighting system may operate in a fashion that allows for lighting redundancy on each end of the vehicle in the event of a lighting controller failure.

Autonomous lawn mower

An autonomous lawn mower is described. The autonomous lawn mower comprises a chassis supporting a podium. In some examples, the podium comprises an upper portion and a lower portion, where the upper portion may support one or more sensors, antennas and/or cameras that may be used to provide environmental information regarding the surroundings of the autonomous lawn mower. The upper portion may be detached from the lower portion such that the upper portion is calibrated prior to the upper portion being coupled to the lower portion.

Mini or micro LED-based light module configured to perform plural light functions seamlessly with different light guides in unitary assembly

A multi-function lighting assembly provides multiple vehicle lighting functions (e.g., rear vehicle tail light and fog light) using a single printed circuit board substrate having mini or micro chip scale package LEDs or their unpackaged LED dies. LEDs for respective ones of the different lighting functions are separately controlled. LEDs controlled for respective functions can be interspersed, or disposed in different areas of LEDs having the same lighting function. A layer of optic components is disposed relative to the outputs of the LEDs and has different optic components for the LEDs of the respective lighting functions (e.g., collimator optics over LEDs controlled to provide a bright concentrated light output, and a diffuser over the LEDs controlled to provide a diffused light output). The multi-function lighting assembly can be employed as a universal board for seamless and convenient integration into various rear lamps having specific inner tail lenses.
