In some specific embodiments, a light source 1, and a reflector 4, an inner cover 2 and a thick wall 3 arranged sequentially along a light exit direction are arranged in the housing. The reflector 4 is configured to reflect light emitted from the light source 1 to the inner cover 2, and emit the light through the inner cover 2 and the thick wall 3 sequentially. The inner cover 2 and the thick wall 3 each have a one-piece structure, and two ends of the light source 1, two ends of the inner cover 2 and two ends of the thick wall 3 extend towards two sides of a vehicle and extend to the side lamp regions 92.
The reflector 4 reflects the light emitted from the light source 1 and emits the light through the inner cover 2 and the thick wall 3 sequentially, so that a light may be emitted from a light-emitting surface uniformly. By means of the cooperation between the light source 1 and the inner cover 2 and the thick wall 3, an excellent light-emitting effect of the vehicle lamp may be achieved, the granular sensation during light emitting is eliminated, and the user experience is improved.
The light source 1, the inner cover 2 and the thick wall 3 each have a one piece structure, which removes physical gaps between a plurality of lamps from design, so that the structure is more continuous, forming a through-type seamless and uniform lighting effect in static and lit states. In the static state, the thick wall 3 has a through-type structure, so that the structure is uninterrupted and the visual effect is consistent. In the lit state, the light-emitting surface is one-piece and through-type, and the thick wall 3 of the one piece structure allows the light to be emitted from the light-emitting surface uniformly with no interruption and no obvious dark regions.
The two ends of the light source 1, the two ends of the inner cover 2 and the two ends of the thick wall 3 extend towards the two sides of the vehicle and extend to the side lamp regions, which may maximize the lighting length, light up a larger area, meet the modeling needs of consumers, and allow the lamp to more naturally reflect its streamline and lighting artistry.
The light source 1 is coupled to the reflector 4, the reflector is configured to reflect the light emitted from the light source 1 and emit the light through the inner cover 2 and the thick wall 3 sequentially, so that the light may be emitted from the light-emitting surface uniformly.

In some embodiments, the outer cover 6 is provided with a protrusion extending in an extension direction of the outer cover 6, the housing 5 is provided with a slot extending along an extension direction of the housing 5, and the protrusion is clamped in the slot. By means of the cooperation between the continuous protrusion and the continuous slot, the contact area between the housing and the outer cover is increased, and the stability of coupling is improved.
In some specific embodiments, the slot includes a first side wall and a second side wall. A fastener passes through the first side wall, the protrusion, and the second side wall in sequence to fix the housing 5 and the outer cover 6. The protrusion is fixed to two side walls of the slot by the fastener, improving the stability of coupling. The fastener may be either a screw or a gun nail.

The housing 5 is coupled to the outer cover 6 through the structural adhesive, and the sealing performance between the housing 5 and the outer cover 6 may be improved. The structural adhesive includes but is not limited to a two-component silicone, a single-component silicone, a PUR hot melt adhesive, and a Sika adhesive.
Along the extension direction of the thick wall 3, the thick wall 3 includes a first end 31 and a second end 32, and a distance from the first end 31 to the second end 32 may be greater than 1500 mm, so that the light-emitting surface of the thick wall 3 may meet lighting needs. A length of thick wall 3 may be greater than 1500 mm, which may maximize the lighting length, light up a larger area, meet the modeling needs of consumers, allow the lamp to more naturally reflect its streamline and lighting artistry, and may better show the aesthetic feeling of modeling and lighting of the lamp to consumers. By means of the cooperation between the inner cover 2 and the thick wall 3, the light is emitted from the light-emitting surface uniformly. When the lamp is viewed from the front, the effect is beautiful, and the brightness of lighting is relatively uniform when the whole thick wall 3 is lit up, thus improving the user experience.
It should be noted that the inner cover 2 may be made of any materials that meet the light transmittance requirements. In some embodiments, the inner cover 2 is made of a material with a light transmittance greater than or equal to 90%. In some embodiments, the inner cover 2 is a thin-walled injection molded member for optical homogenization. The thick wall 3 may be made of any materials that meet the light transmittance requirements. In some embodiments, the thick wall 3 is made of a material with a light transmittance greater than or equal to 90%. In some embodiments, the thick wall 3 is an injection molded member for optical homogenization. The reflector 4 may be a metal material or a plastic material. In some embodiments, the reflector 4 is aluminized or non-aluminized plastic injection molded member for light focusing.
It should also be noted that the inner cover 2 may be made of a light diffusion material. In some embodiments, the inner cover 2 may be a polycarbonate (PC) light diffusion plastic, i.e., a light-transmitting but opaque light diffusion material particle formed by using a transparent PC plastic as a base material, adding a certain proportion of light diffusion agent and other additives, and polymerizing them through a special process. In some embodiments, the light diffusion materials may be made by adding materials that scatter light, such as BaSO4, to a colorless transparent PC base material. In some embodiments, the light diffusion materials may further be made by adding materials that scatter light, such as macromolecular cluster materials, to the colorless transparent PC base material. In some embodiments, the inner cover 2 is made by adding BaSO4 or macromolecular cluster materials to the colorless transparent PC base material.
The inner cover 2 has a one-piece structure, which removes physical gaps between the plurality of lamps from design, so that the structure is more continuous, forming a through-type seamless and uniform lighting effect in static and lit states. In the static state, the inner cover 2 has a through-type structure, so that the structure is uninterrupted and the visual effect is consistent. In the lit state, the light-emitting surface is one-piece and through-type, and the inner cover 2 of the one piece structure allows the light to be emitted from the light-emitting surface uniformly with no interruption and no obvious dark regions.
The light source 1 includes a circuit board and an LED light source, and the circuit board may be a PCB board or a PCBA board. The circuit board is electrically coupled to the LED light source to allow the LED light source to be lit up or extinguished.
In some specific embodiments, the inner cover 2 includes a first light entrance surface 21 and a first light exit surface 22, and the thick wall 3 includes a second light entrance surface 33 and a second light exit surface 34, and a distance L1 (not illustrated in figures) from the first light exit surface 22 to the second light entrance surface 33 satisfies 0≤L1≤1 mm. The reflector 4 reflects the light emitted from the light source 1 to the inner cover 2 and emits the light through the inner cover 2 and the thick wall 3 sequentially, so that the light may be emitted from the second light exit surface 34 uniformly. By means of the cooperation between the inner cover 2 and the thick wall 3, the excellent light-emitting effect of the vehicle lamp may be achieved, the granular sensation during light emitting of the second light exit surface 34 is eliminated, and the user experience is improved. The distance from the first light exit surface 22 to the second light entrance surface 33 may be any numbers between 0 to 1 mm, such as 0, 0.2 mm, 0.4 mm, 0.6 mm, 0.8 mm, and 1 mm. When the distance between the first light exit surface 22 and the second light entrance surface 33 is between 0 and 1 mm, the light may be emitted from the light-emitting surface uniformly, that is, it satisfies a linear ratio≥75%. The linear ratio may reflect the uniformity of the linear distribution, which refers to the ratio of a minimum value min and a maximum value max of the brightness in a through line (i.e., a continuous extending line on the second light exit surface 34 of the thick wall 3 along the extension direction of the thick wall 3 (i.e., the Y direction)). For example, according to the structure of the present application, a brightness distribution (unit is nit) curve in the through line of the second light exit surface 34 is measured, which satisfies condition A: min/max>75%; and condition B: under the premise that the data is not homogenized, the linear data fluctuation range Δ<10% of the minimum value min. Furthermore, the uniformity of the light-emitting surface of the lamp may also be measured by the brightness distribution of point domains, in which the brightness of a plurality of points (such as 10 to 100) in a certain area (such as a circle area, a quadrilateral area, etc.) on the light-emitting surface is measured, and the uniformity of the light-emitting surface is evaluated by comparing a ratio of the minimum value Nmin and the maximum value Nmax of point brightness (unit is nit) Nmin/Nmax (i.e., a regional ratio). For each point, multiple measurements are made, and an average value of the brightness measured servers as a brightness value of the point. The lamp according to the present application satisfies Nmin/Nmax>0.9 on the second light exit surface 34.
The smaller the distance from the first light exit surface 22 to the second light entrance surface 33, the better the uniformity of light emitting.
In some embodiments, when the distance from the first light exit surface 22 to the second light entrance surface 33 is 0, the first light exit surface 22 is snugly fitted to the second light entrance surface 33 without a gap, so that the light is emitted from the second light exit surface 34 uniformly, the granular sensation during light emitting of the second light exit surface 34 is eliminated, the excellent light-emitting effect of the vehicle lamp may be achieved, and the user experience is improved.
In some specific embodiments, along a vertical direction of the extension direction of the thick wall 3, the thick wall 3 includes a top surface 37 and a bottom surface 38. The bottom surface 38 is provided with a first protruding part 35, the top surface 37 is provided with a second protruding part 36, and the first protruding part 35 and the second protruding part 36 extend along the extension direction of the thick wall 3. The first protruding part 35 and the second protruding part 36 may avoid seeing the internal structure of the lamp from the thick wall 3, such as the light source 1, the reflector 4, etc., thus improving the sensory quality of the lamp. The thick wall 3 makes the structure more continuous, forming the through-type seamless and uniform lighting effect in static and lit states. In the static state, the thick wall 3 has the through-type structure, so that the structure is uninterrupted and the visual effect is consistent. In the lit state, the second light exit surface 34 is one-piece and through-type, the light is emitted from the second light exit surface 34 without interruption, and the thick wall 3 of the one piece structure allows the light to be emitted from the second light exit surface 34 uniformly with no obvious dark regions.
Along the vertical direction of the extension direction of the thick wall 3, a height H1 of the first protruding part 35 satisfies: 2 mm≤H1≤20 mm, and a height H2 of the second protruding part 36 satisfies: 2 mm≤H2≤20 mm, which avoids forming a reflection of the internal installation structure on the thick wall 3, improves the sensory quality of the lamp, allows the light to be emitted from the second light exit surface 34 in a one-piece and through-type manner in the lit state, and allows the light to be emitted from the second light exit surface 34 with no interruption and no obvious dark regions.
Along a direction from the second light entrance surface 33 to the second light exit surface 34, a thickness T1 of the first protruding part 35 satisfies: 2 mm≤T1≤10 mm, and a thickness T2 of the second protruding part 36 satisfies: 2 mm≤T2≤10 mm, which avoids forming a reflection of the internal installation structure on the thick wall 3, improves the sensory quality of the lamp, allows the light emitted from the second light exit surface 34 in one-piece and through-type manner in the lit state, and allows the light to be emitted from the second light exit surface 34 with no interruption and no obvious dark regions.
In some specific embodiments, the second light entrance surface 33, the second light exit surface 34, the top surface 37 and the bottom surface 38 each are a smooth surface, that is, the second light entrance surface 33, the second light exit surface 34, the top surface 37 and the bottom surface 38 are flat or optically polished surfaces, like the effect of a glass surface, and the sensory quality of the lamp is improved.
In some specific embodiments, the through-type lamp mounting structure further includes the housing 5 and the outer cover 6; the housing 5 is coupled to the outer cover 6 to define the light chamber. The light source 1, the inner cover 2, the thick wall 3 and the reflector 4 are arranged in the light chamber. The housing 5 may have a structure made of a black PP-GF30 material and configured to support the weight of the lamp. The outer cover 6 is a black or colorless transparent plastic injection molded member covered at an outermost side, which may be single-color or two-color or double-layer.
As illustrated in
An extension length of the outer cover 6 matches the housing 5, as illustrated in
In some specific embodiments, the outer cover 6 includes a third light exit surface 63, and the third light exit surface 63 is parallel to the second light exit surface 34. The third light exit surface 63 is basically parallel to the second light exit surface 34, and the third light exit surface 63 and the second light exit surface 34 have a substantially identical length, which maximizes the lighting length, so that the lamp more naturally reflects its streamline and lighting artistry, and may better show aesthetic feeling of the modeling and lighting of the lamp to consumers. The third light exit surface 63 is parallel to the second light exit surface 34, so that the light emitted from the third light exit surface 63 is one-piece and through-type, the light is emitted from the third light exit surface 63 uniformly, and the light is emitted from the third light exit surface 63 with no interruption and no obvious dark regions. When the lamp is viewed from the front, the effect is beautiful, and the brightness of lighting is relatively uniform when the whole lamp is lit up, thus the excellent light-emitting effect of the vehicle lamp may be achieved, and the user experience is improved.
In some specific embodiments, a distance L2 between the third light exit surface 63 and the second light exit surface 34 satisfies: 3 mm≤L2≤10 mm. In the lit state, the light emitted from the third light exit surface 63 is one-piece and through-type, the light emitted from the third light exit surface 63 uniformly, and the light is emitted from the third light exit surface 63 with no interruption and no obvious dark regions. When the lamp is viewed from the front, the effect is beautiful, and the brightness of lighting is relatively uniform when the whole lamp is lit up, thus the excellent light-emitting effect of the vehicle lamp may be achieved, and the user experience is improved.
