Description

Big curved surface little space luminous logo and car light Technical Field The utility model relates to the technical field of car lamps, in particular to a large-curved-surface small-space luminous logo and a car lamp. Background Luminescent logos have gained increasing popularity in recent years, as part of the location function, becoming increasingly a new model of vehicle. The character type logo is generally positioned close to the side wall of the car body, the uniformity requirement of the logo light emission is high, and the radian of the molding surface is required to be large and the occupied space is small. In the prior art, as disclosed in a patent with an authority number of CN218348579U, a small-sized general optical device for realizing luminous characters and a car lamp thereof are disclosed, and the technical scheme is characterized by comprising a decorative ring, a light guide, a support and an LED module, wherein the LED module and the light guide are fixed on the support to form a luminous source assembly, the luminous source assembly is fixedly connected with the decorative ring to form an optical device assembly, wherein the double-layer light guide adopts transparent materials, the surface of a front-layer light guide adopts a hot stamping technology to realize luminous LOGOs, the device can meet the display of personalized characters or brands LOGO of the appearance design of car parts and occupies small space, but the surface is required to be flat, the hot stamping technology limits the angle of a luminous surface to be not less than 150 degrees, the adaptation of a large-radian luminous LOGO is difficult to realize, and due to the space limitation, the distance between a rear-layer light guide and the front-layer light guide is relatively close, the reflection teeth on the rear-layer light guide are visible when being observed, the LOGO lamp has transparent appearance in a non-lighting state, and is not matched with the static appearance of the main stream of the scattering material of the lamp in the current position under the lighting working condition. In addition, in order to satisfy the demand of the luminous logo of large radian, also can adopt the scheme of aluminizing on LED direct projection cooperation spotlight ware, the outer lamp shade, but this kind of scheme space requirement is great, and the homogeneity of light distribution need rely on control cladding material thickness, sometimes the structure restriction is difficult to ensure the uniformity of cladding material, appears the defect that light distribution homogeneity is poor easily. Disclosure of utility model The utility model aims to solve the technical problems that the combination of small occupied space and light-emitting uniformity is difficult when the radian requirement of a light-emitting surface is large, and provides a large-curved-surface small-space light-emitting logo and a vehicle lamp, which realize the design of a large curved surface model and have better light-homogenizing effect. The technical scheme includes that the large-curved-surface small-space luminous logo comprises an inner lampshade, a decorative ring, a reflecting mirror and an LED module, wherein a protruding part is arranged on one side of the inner lampshade, the decorative ring is sleeved on the protruding part, and one side, close to the protruding part, of the inner lampshade is welded with the decorative ring by ultrasonic waves; The LED module is arranged above the reflector, the LED module and the reflector are riveted and fixed to form a light source sub-assembly, the reflector is arranged on one side of the inner lampshade far away from the decorative ring in a semi-surrounding mode, and one side of the reflector, which is close to the inner lampshade, is connected with the decorative ring, so that the light source sub-assembly and the decorative ring form a luminous logo; The reflecting mirror is a concave mirror, a reflecting bowl is arranged at the concave surface of the reflecting mirror, a notch of the reflecting mirror faces to the protruding part of the inner lampshade, and the reflecting mirror and the decorative ring form a semi-surrounding shape to the inner lampshade, so that the first-step light homogenizing effect in a small space is realized through the reflecting bowl. Further, a welding rib is arranged on one side, close to the protruding portion, of the inner lampshade, and the welding rib is a connecting portion formed by ultrasonic welding or laser welding of the inner lampshade and the decorative ring, so that the size of a window of the decorative ring is guaranteed, and meanwhile the fixing effect is enhanced. In order to solve the technical problem, a black paint layer is arranged on the outer side surface of the inner lampshade far away from the reflector, the part of the black paint layer at the protruding part is removed through laser carving to form a hollowed-out shape, the hollowed-out s
