Description

Technical Field

[0001] This utility model relates to a starry sky light for vehicles. Background Technology

[0002] Car lights are crucial components of automobiles, serving functions such as illumination, information communication, and improving vehicle visibility. Modern car lights are no longer limited to functionality and practicality; aesthetics are also highly valued. Many lights utilize polygonal cut surfaces to increase light transmission and feature various shapes. Chinese Patent 202510534034.7 discloses a car light and vehicle with a dazzling starry sky effect, comprising: a PCB board with a light source mounted on it; a reflector with a first patterned area; and a transparent inner mirror connected at one end to the reflector, with a second patterned area on the side of the inner mirror closest to the reflector. The light source is positioned corresponding to the reflector and the inner mirror. The light from the light source can be reflected by the first patterned area, pass through the second patterned area, and exit through the inner mirror; or the light can directly pass through the second patterned area and exit through the inner mirror.

[0003] Chinese Patent 201821359238.3 discloses a reflective position light with a starry sky effect, including a reflective surface and an LED module. The reflective surface is composed of a base surface and several reflective surface units arranged on the base surface. The base surface is a continuous and flat curved surface with a cross-sectional shape of a concave curve or a convex curve. The reflective surface units are arranged randomly and have different reflection directions. The base surface is divided into a grid by several intersecting curves, and the reflective surface units are arranged on the grid nodes.

[0004] Chinese Patent 202421403218.7 discloses a concealed ambient light, including a housing, a circuit board, an inner lens, and an outer lens. The outer lens and the housing together form a receiving cavity. The circuit board and the inner lens are both located in the receiving cavity. The inner lens is located between the circuit board and the outer lens, and a light source is provided on the circuit board. A semi-transparent layer is provided on the outer surface of the outer lens, a hollow layer is provided on the inner surface of the outer lens, and a first pattern is provided on the outer surface of the inner lens.

[0005] The drawbacks of the above technical solutions are that they are relatively complex in structure and have high costs.

[0006] Therefore, how to provide a simple and low-cost automotive starlight has become a problem that the industry needs to solve. Utility Model Content

[0007] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a vehicle starlight lamp with simple structure and low cost.

[0008] To achieve the above objectives, this utility model provides a vehicle starlight light, which includes:

[0009] Mounting base, lamp panel, inner light-transmitting panel, concave curved panel, and outer light-transmitting panel; wherein, the lamp panel, inner light-transmitting panel, concave curved panel, and outer light-transmitting panel are all mounted on the mounting base; the lamp panel, inner light-transmitting panel, concave curved panel, and outer light-transmitting panel are arranged from back to front;

[0010] Several LED beads are provided on the outer surface of the light panel;

[0011] The inner light-transmitting panel is a transparent component with several fine curved surface units on it;

[0012] The concave curved panel is a curved panel with its inner panel surface protruding backward and its outer panel surface concave; the concave curved panel includes a transparent substrate and a surface paint layer, and the surface paint layer has several light-transmitting holes laser-engraved on it.

[0013] The outer light-transmitting panel is a transparent component.

[0014] In this utility model, the mounting base serves to house the lamp plate and the inner light-transmitting plate.

[0015] In this invention, the fine curved surface unit has a fragmented structure, which is not necessarily spherical; it can also be other shapes such as a square. The function of the fine curved surface unit is to scatter the light emitted by the lamp panel.

[0016] In this invention, the fine curved surface unit is a concave mirror unit or a convex mirror unit.

[0017] In this design, the light from the light panel is scattered by the inner light-transmitting plate and then emitted through the light-transmitting holes. To the observer, the light appears as twinkling dots, resembling a starry sky. This starry effect is particularly pronounced when the car or the observer moves.

[0018] The automotive starlight of this invention is mainly used for automotive interior or position lights, etc.

[0019] According to another specific embodiment of the present invention, the surface paint layer is located on the inner surface of the concave curved panel, close to the inner light-transmitting panel.

[0020] According to another specific embodiment of this utility model, the outer light-transmitting plate is a smoked black transparent part.

[0021] According to another specific embodiment of this utility model, the lamp panel, the inner light-transmitting panel, the concave curved panel, and the outer light-transmitting panel are arranged in parallel.

[0022] According to another specific embodiment of the present invention, the fine curved surface unit is disposed on the outer surface of the inner light-transmitting plate, and the inner surface of the inner light-transmitting plate is a smooth surface.

[0023] According to another specific embodiment of the present invention, the inner surface of the inner light-transmitting plate is a plane or an arc surface.

[0024] According to another specific embodiment of this utility model, the fine curved surface unit is a concave mirror unit.

[0025] In this design, the concave mirror unit is square, for example, with a size of 2×2mm or 4×4mm; the size requirement of the concave mirror is not strict, and the LED is roughly located at the focal point of the concave mirror.

[0026] According to another specific embodiment of this utility model, the fine curved surface unit is a convex mirror unit.

[0027] In this design, the convex mirror unit is not a single sphere, but a combination of two spheres with different curvatures; for example, the edge dimension is R5 and the center dimension is R10.

[0028] The dimensions of the convex mirror are strictly required (provide a set of dimensions as needed, without the need for formula derivation).

[0029] According to another specific embodiment of the present invention, both the outer and inner surfaces of the inner light-transmitting plate are provided with fine curved surface units, which are convex mirror units.

[0030] According to another specific embodiment of this utility model, the convex lens unit is a spherical cap, or a spherical cap-like shape whose height is adjusted. A spherical cap refers to the part remaining after a sphere is cut off by a plane; a spherical cap-like shape refers to a geometric shape formed by elongating or shortening a spherical cap.

[0031] This invention solves the technical problems of complex structure and high cost of general car lights. By adding an inner light-transmitting plate, the number of lamp beads can be reduced; the structure is simple and the cost is low; the concave curved panel can enhance the sense of layering, depth and three-dimensionality of the starry sky.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description
