This application relates to the field of vehicle technology and discloses a low beam module and a vehicle. The low beam module includes a light source assembly for emitting light; a reflector bowl defining a reflective cavity open at both ends, the reflector bowl being disposed around the periphery of the light source assembly; and a lens disposed on the side of the reflector bowl opposite to the light source assembly, the lens having a cross-section formed as an annular segment. This low beam module and vehicle, through the synergistic effect of the directional reflection of the reflector bowl and the optical diffusion of the lens, can form a clear cutoff line without the need for a light-blocking plate, expanding the light diffusion angle and light coverage range, improving illumination uniformity, enhancing illumination effect, avoiding glare to other road users, and improving visual comfort.

The utility model discloses a multifunctional white noise sleep sound box of magnetic attraction remote control replaceable mesh cover, the sleep sound box of the utility model is through setting up light guide gap between second casing and light guide cover, the light of light emitting lamp board in the sound box has greater illumination range and illumination angle, and forms diffuse reflection light, and light guide gap still makes light guide cover have suspension, improves the overall appearance and ornamental of product, still is equipped with the remote controller with magnetic attraction charging function, and can be customized as the modeling of any animal as theme design, improves the interestingness and ornamental of product, still sets up the elastic mesh cover on the surface of light guide cover can prevent dust foreign matter from adhering to light guide cover, and the elastic mesh cover can be dismantled and washes at random, effectively keeps the cleanness and health of sleep sound box.
