4results about How to "Large irradiation angle" patented technology

The utility model relates to the technical field of car lamps, in particular to a wide-angle lighting car lamp, a light gathering part is arranged in the middle of a lens, the left side and the right side of the light gathering part are bent backwards to form angle expanding parts, an installation groove is formed in the front face of a shell, and a lighting lamp panel is arranged in the installation groove. The lighting lamp panel is arranged in the mounting groove and divided into a strong light area corresponding to the light gathering part and a light supplementing area corresponding to the angle expanding part, the strong light area and the light supplementing area are each provided with a plurality of LED modules, and the left side wall and the right side wall of the mounting groove are concavely provided with receding notches used for being connected with the angle expanding part. Light of the LED module can penetrate out of the angle expanding part to supplement and illuminate the left edge area and the right edge area of the automobile lamp, meanwhile, the receding notch corresponding to the angle expanding part is formed in the front end of the shell, a receding structure is provided for illumination of the LED module, light is prevented from penetrating out of the side edge, and therefore the irradiation angle of the automobile lamp is enlarged, a driver can conveniently observe the driving condition, and traffic accidents are reduced.

The utility model discloses a shadowless lamp quick adjusting suspension mechanism which comprises a shadowless lamp body and a transverse plate, the two ends of the transverse plate are bent to form connecting parts, side plates are arranged on the outer sides of the connecting parts, a positioning groove is transversely formed in the bottom face of the transverse plate, a positioning block is installed in the positioning groove in a sliding mode, an adjusting base is installed at one end of the positioning block, and a fixing base is installed at the other end of the positioning block. An adjusting opening of an arc-shaped structure is formed in the adjusting seat, an adjusting plate of an arc-shaped structure is arranged in the adjusting opening, one end of the adjusting plate is fixedly connected with the shadowless lamp body, and a lifting rotating mechanism for changing the height and orientation of the shadowless lamp body is installed above the transverse rod. The shadowless lamp is simple in structure, the shadowless lamp can be centered and positioned through the side plates, the head of the shadowless lamp body can be raised and pressed in the mode that the shadowless lamp body moves along the adjusting opening, the irradiation angle of the shadowless lamp body is increased, and the shadowless lamp body can steer and longitudinally move so that adaptability can be improved.

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.
