Referring to fig. 1 to 6, a preferred embodiment of the present invention provides a vehicle lamp without spot defect, including a thick-walled member, an upper decorative frame, a lower decorative frame and a light source portion, the thick-walled member is fixedly clamped in an installation space formed by the upper decorative frame and the lower decorative frame, the light source portion is used for providing uniform incident light for the thick-walled member, the upper decorative frame includes a pressing portion 20, the lower decorative frame includes a supporting portion 30, the pressing portion 20 and the supporting portion 30 are disposed opposite to each other to form a first sub-installation space disposed in a horizontal direction, the first sub-installation space is used for installing the light guide portion 10 for placing the thick-walled member, the light guide portion 10 is inserted into the first sub-installation space when placing, and a limiting portion 11 disposed perpendicular to the light guide portion 10 is closely attached to one side surfaces of the pressing portion 20 and the supporting portion 30, the surfaces of the pressing portion 20 and the supporting portion 30 contacting the thick-walled member are smooth planes as shown in fig. 2, the exposed length of the light guide portion 10 of the thick-walled member is X, the length of the contact region between the pressing portion 20 and the thick-walled member is D, and the thickness of the light guide portion 10 of the thick-walled member is H. The length dimension of the light guide portion 10 of the entire thick-walled member can be selected with reference to the following formula: l is more than or equal to X + D and less than or equal to X + D + H;
wherein X is the exposed length of the thick-walled component light guide portion 10, and L is the total length of the thick-walled component light guide portion 10; the thickness of the limiting part 11 is usually selected between 2mm and 5mm, and X is less than or equal to D; in the embodiment, the total length of the group of thick-wall parts is 42mm, wherein the exposed length of the thick-wall parts is 20mm, the length of the contact area between the pressing part 20 and the thick-wall parts is 20mm, the thickness value of the limiting part 11 is 2mm, and the selection of the thickness value of the limiting part 11 is determined according to the size of a specific vehicle lamp. The length of the whole thick-wall part influences the lighting effect of the car lamp, the car lamp is better when the car lamp is longer, but the anti-vibration capability of the car lamp is directly reduced after the car lamp is lengthened, and the thick-wall part obtained by the calculation method provided by the formula can not only take the appearance into consideration, but also ensure the anti-vibration performance.
As shown in fig. 1, the thick-walled member includes a light guide portion 10 and a limiting portion 11, the light guide portion 10 is vertically disposed on the limiting portion 11, and the limiting portion 11 is disposed in a second sub-installation space formed by the side wall surfaces of the pressing portion 20 and the supporting portion 30 and the light source portion. The thick-wall part is set to be similar to a T-shaped structure, so that after installation, the thick-wall part can be stably clamped in the installation space through interaction of the first sub-installation space and the second sub-installation space, the installation and fixation problems of the thick-wall part are solved, and the surfaces which are in contact with the thick-wall part and can form a total reflection light path in the thick-wall part are smooth planes without complex configurations, so that the quantity of reflected stray light formed by complex structures can be greatly reduced.
As shown in fig. 1, the light source portion includes a light source emitting portion 42, a reflecting portion 41, a light homogenizing sheet 40, and a lower contact plate, wherein the end portion of the connecting portion 21 of the reflecting portion 41 and the lower contact plate are both provided with a clamping groove, and two sets of clamping grooves are respectively buckled on the upper and lower end portions of the light homogenizing sheet 40 far away from the thick-walled member so as to fix the light homogenizing sheet 40 on the thick-walled member. The light of the light source emitting part 42 reaches the reflecting part 41 and then is reflected by the multiple groups of reflecting step surfaces 411 on the internal reflecting surface of the reflecting part 41, so that the emitting direction of the light can be changed, the inclination directions of the multiple groups of reflecting step surfaces 411 are arranged at an angle of 43-47 degrees with the vertical direction, the inclination angles of different positions of the reflecting step surfaces 411 are determined by the angle of the incident light incident on the mirror surface of the reflecting step surfaces, and finally the purpose is that the emitted light after being reflected by the multiple groups of reflecting step surfaces 411 is formed into a group of parallel light and vertically projected on the dodging sheet 40. The specific inclination angles of the plurality of sets of reflective step surfaces 411 can be determined by simulation using existing light simulation software. If the incident light is parallel light, the inclination angle of the plurality of sets of reflecting step surfaces 411 may be set to 45 °, and the emergent light is projected onto the light uniformizing sheet 40 as parallel light.
The light homogenizing plate 40 is a rectangular lens with scattering particles dispersed therein, and can be made of PC2407 which is transparent material and matched with the required color number particles by injection molding. The light homogenizing sheet 40 in the invention is PC-2407-.
The surface of the thick-wall part is a smooth plane and does not need any surface treatment. Compared with the prior vehicle lamp, in order to solve the problem of stray light emission, the surface of the light guide component is subjected to dermatoglyph treatment so as to homogenize the emitted light and then emit the light or add black paint on the head of the light guide component, so that the operation mode of reducing the stray light brightness such as bright spots and the like is realized.
A connecting part 21 is fixedly arranged on one side surface of the pressing part 20 far away from the thick-wall part, and the connecting part 21 is fixedly connected with the connecting part 21 of the reflecting part 41. The fixing connecting part 21 of the upper decorative frame is arranged at one end far away from the thick-wall part, so that the complex connecting structure of the connecting part 21 cannot be irradiated by incident light, and in addition, stray light reflection cannot be formed. One side of the supporting part 30 far from the thick-wall part is fixed with a clamping end head 31, and the clamping end head 31 is fixed on a connecting rib position of the car lamp. The fixing connection part 21 is away from the thick wall member, and no stray light reflection is formed by providing a connection structure with other components or other mounting positions of the vehicle lamp on one side of the pressing part 20 and the support part 30 away from the thick wall member, thereby fixing and mounting the upper decorative frame, the lower decorative frame and the light source part.
Fig. 4 and 6 are lighting effect diagrams of the conventional vehicle lamp, and fig. 3 and 5 are lighting effect diagrams of the vehicle lamp in the present invention, which are obvious from the above two diagrams that a plurality of sets of disordered rays are emitted from the upper portion of the thick-walled member when the conventional vehicle lamp is lit, and due to the intervention of the disordered rays, a part of the disordered rays are emitted from the front emitting surface of the thick-walled member, so that the illumination brightness of the surface of the front emitting surface is uneven, and in addition, due to the different emitting angles of the plurality of sets of disordered rays, the occupied light path emitting space is larger, so that the external observation range is wider, and the observation range is easier to observe. When the vehicle lamp is turned on, the light on the emigration surface of the thick-wall part is uniform, the upper surface of the thick-wall part has almost no emergent light, only two groups of parallel regular light are emitted, and the two groups of emergent light can be observed only at the position of the fixed emergent light path, and the emergent position of the light path is difficult to reach by the eyes of a person after the vehicle lamp is usually installed on a vehicle, so that the brightness of the upper surface of the thick-wall part is basically consistent.
The working principle is as follows:
as shown in fig. 1, when the vehicle lamp is turned on, the light emitted from the light source emitting portion 42 reaches the internal reflection surface of the reflection portion 41, and after the light is reflected by the plurality of sets of reflection step surfaces 411, the light is vertically projected on the light uniformizing sheet 40 in the form of parallel light, and after the light is uniformly scattered by the light uniformizing sheet 40, the light enters the limiting portion 11 of the thick wall member again, at this time, a part of the light is projected in parallel along the light guide portion 10, as an exit light path shown by a parallel solid line in fig. 1, while a small part of the light is projected on an area where the pressing portion 20 and the supporting portion 30 are in contact with the limiting portion 11 and is reflected in the area, and then the plurality of sets of reflected light are projected on the upper surface and the lower surface of the light guide portion 10 after being reflected for a plurality of times, and the stray light reflected on the upper surface is shielded by the area where the pressing portion 20 is in contact with the thick wall member and cannot be projected, as an exit light path shown by a point in fig. 1, the stray light reflected to the lower surface is blocked by the contact area of the support portion 30 and the thick-walled member and is not emitted, and the light path is not shown in the figure like the outgoing light path shown by the dotted line in fig. 1, so that the light is uniformly emitted only from the frontmost surface of the light guide portion 10. In addition, two sets of light rays are reflected at the two sets of lower corners of the pressing portion 20 and then emitted from the upper surface of the thick-walled member, as shown by the light paths indicated by the two broken lines in fig. 1, and the two sets of light rays are mutually parallel regular line segments, and the two sets of emergent light rays can be observed only at the positions of the fixed emergent light paths, and the light paths are difficult to reach and therefore difficult to observe by human eyes after being installed on a vehicle.
The above description is intended to describe in detail the preferred embodiments of the present invention, but the embodiments are not intended to limit the scope of the claims of the present invention, and all equivalent changes and modifications made within the technical spirit of the present invention should fall within the scope of the claims of the present invention.
