Indoor lighting device for vehicle with light guide panel
A recently granted patent (Publication Number: US11999291B2) discloses an innovative indoor lighting device for vehicles. The device comprises a substrate, a row of light sources assembled with the substrate, and a light guide panel. The light guide panel includes incidence parts for light emission, a diffusion area for reflecting and diffusing light, and a visual field area for emitting light outside the device. Additionally, the device features light diffusion holes surrounded by transmission, reflection, and diffusion planes to control the direction and diffusion of light effectively.
Furthermore, the patent also covers a lighting control system for vehicles, incorporating a light source module, a sensor module to detect vehicle driving states, and a controller to sequentially activate the light sources based on sensor information. The system ensures a predetermined turning-on interval between light sources, with specific luminance adjustments for individual sources. The sensor module includes various sensors like speed sensors, front collision detection sensors, or lane departure detection sensors. The light source module, similar to the indoor lighting device, consists of a light guide panel with incidence parts, diffusion areas, visual field areas, and light diffusion holes, all designed to optimize light emission and diffusion for enhanced visibility and aesthetics within the vehicle.
