For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0026] Reference below Figure 1-Figure 3 A vehicle lamp 100 according to an embodiment of the present invention is described.

[0027] like Figure 1As shown, the vehicle lamp 100 according to the embodiment of the utility model includes a lamp housing 8, an outer lampshade 7, an inner lampshade 5, a light homogenizer 4 and a light emitting member 2. The outer lampshade 7 is detachably connected to the lamp housing 8 and forms a lamp cavity with the lamp housing 8. The light emitting member 2 is installed in the lamp cavity and is located on the light incident side of the outer lampshade 7. The light homogenizer 4 is arranged on the light path between the light emitting member 2 and the outer lampshade 7, and the inner lampshade 5 is arranged on the light path between the light homogenizer 4 and the outer lampshade 7.

[0028] That is to say, the light emitted by the light-emitting component 2 can pass through the light-homogenizing component 4, the inner lampshade 5 and the outer lampshade 7 in sequence and then be projected out, wherein the light-homogenizing component 4 can make the light emitted by the light-emitting component 2 evenly scattered in the light-homogenizing component 4, so that the light is projected toward the inner lampshade 5 in the form of uniform surface light after passing through the light-homogenizing component 4, and the evenly projected surface light is then projected to the outside through the inner lampshade 5 and the outer lampshade 7 in sequence. By setting the light-homogenizing component 4, the uniform lighting effect of the vehicle lamp 100 can be better achieved.

[0029] The utility model adds a light homogenizer 4 before the inner lampshade 5 and the outer lampshade 7. It should be noted that the outer lampshade 7 and the inner lampshade 5 are uniformly transparent lampshades. By adding the light homogenizer 4 before the inner lampshade 5 and the outer lampshade 7, the problem of dark areas in the upper viewing angle caused by the angle between the inner lampshade 5 and the outer lampshade 7 can be improved when the light-emitting component 2 emits light, thereby improving the lighting uniformity of the vehicle lamp 100. In the related art, in order to achieve a uniform lighting effect of the car lamp 100, the outer lamp cover 7 is often directly made into a light homogenizer 4, or the light homogenizer 4 is directly arranged on the light incident side of the outer lamp cover 7, so that the light homogenizer 4 can be easily seen when the car lamp 100 is not lit. Therefore, when the car lamp 100 is not lit, it is easy to affect the visual aesthetics of the car lamp 100, that is, the car lamp 100 has a strong plastic feel. In the present utility model, since both the inner lamp cover 5 and the outer lamp cover 7 are transparent lamp covers, the visual aesthetics is better. In some examples, when the car lamp 100 is not lit and the car lamp 100 is observed from the outside, it is not easy to directly see the light homogenizer 4 due to the obstruction of the assembly structure of the inner lamp cover 5 and the outer lamp cover 7, thereby improving the visual aesthetics of the car lamp 100 to a certain extent.

[0030] In addition, in the present invention, due to the design of the light homogenizing cover 4, the emission direction of the light can be adjusted well. Figure 1 The inner lampshade 5 is made of two-color injection molding, and the light-emitting surface has an angle with the light-emitting direction of the light. The inner lampshade 5 is black, and a dark area will be formed when the headlight is viewed from above. Therefore, the angle of the light-emitting surface of the inner lampshade 5 can be better matched by adjusting the angle of the light-emitting surface of the inner lampshade 5, so that the light can be better projected to the light-emitting surface of the outer lampshade 7 after passing through the inner lampshade 5, thereby making it less likely for the outer lampshade 7 to have a dark area.

[0031] Therefore, according to the vehicle lamp 100 of the embodiment of the utility model, by setting the light homogenizing member 4, the vehicle lamp 100 can have a better light homogenizing effect, and when the light-emitting member 2 emits light, the vehicle lamp 100 can emit uniform light; further, by setting the inner lampshade 5 between the light homogenizing member 4 and the outer lampshade 7, both the inner lampshade 5 and the outer lampshade 7 are transparent lampshades, which meet the regulations and have better visual aesthetics, can improve the visual aesthetics of the vehicle lamp 100 to a certain extent, and also make it less likely for dark areas to appear in the outer lampshade 7.

[0032] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the inner lampshade 5 has a grille portion and a smooth portion. In the light emitting direction of the light emitting component 2, the light homogenizing component 4 has a first light homogenizing area 41 opposite to the grille portion and a second light homogenizing area 42 opposite to the smooth portion. The thickness of the first light homogenizing area 41 is less than the thickness of the second light homogenizing area 42.

[0033] That is to say, by constructing a grille portion on the inner lampshade 5, a pattern can be arranged on the inner lampshade 5, such as a warning pattern of a turn signal light and a warning pattern of a reverse light, so as to better warn passers-by during the driving of the vehicle. Furthermore, the color of the inner lampshade 5 can be red.

[0034] Furthermore, if Figure 1-Figure 3 As shown, after a pattern is constructed on the inner lampshade 5, the pattern may be constructed in three dimensions in order to be visible. Therefore, the pattern may have a certain light-blocking property after being constructed, that is, it may hinder the passage of light. Therefore, after the lamp 100 is turned on, it may easily cause uneven light emission of the lamp 100. In the present application, the thickness of the first uniform light area 41 is made smaller than the thickness of the second uniform light area 42, that is, the light intensity of the light emitted by the light-emitting component 2 passing through the first uniform light area 41 is the first light intensity, and the light intensity of the light emitted by the light-emitting component 2 passing through the second uniform light area 42 is the second light intensity. Since the thickness of the first uniform light area 41 is small, the first light intensity is greater than the second light intensity. Therefore, in the present utility model, even if a pattern is constructed on the inner lampshade 5, the lamp 100 may have a relatively uniform light emission effect.

[0035] Optionally, the grille portion is provided with a grille 51, that is, the utility model constructs a pattern through the grille 51, and the structure is simple. For example, the grille 51 can be constructed integrally with the inner lampshade 5 by injection molding, which can reduce the production cost to a certain extent.

[0036] Of course, it is understandable that the grille portion can also be constructed into a pattern by etching or pasting a light-transmitting layer, and this application does not impose any limitation thereto.

[0037] In some embodiments of the present invention, there is a transition area 43 with gradually increasing thickness between the first uniform light area 41 and the second uniform light area 42. Therefore, when the light passes through the uniform light element 4, the light intensity gradually changes from the first uniform light area 41 to the second uniform light area 42, which can help improve the uniformity of the light after passing through the inner lampshade 5, and can further improve the uniform light output effect of the vehicle lamp 100.

[0038] Furthermore, the light incident surface and the light emitting surface of the transition region 43 are both arc surfaces, which can effectively improve the structural strength of the light homogenizer 4 and avoid stress concentration, and also improve the aesthetics of the light homogenizer 4 to a certain extent.

[0039] In some embodiments of the present invention, the light homogenizer 4 is formed of an integrally formed light homogenizer material, and thus the shape, thickness, etc. of the light homogenizer 4 can be adjusted according to actual needs to better meet actual needs.

[0040] Optionally, the light homogenizer 4 may also be constructed by etching or pasting a light homogenizer layer on the light-transmitting plate, and the present invention does not limit this.

[0041] In some embodiments of the present invention, the vehicle lamp 100 further includes a light blocking member 6, which is fixedly connected to the inner lampshade 5, and is used to construct a light-homogenizing space between the light blocking member 6, the inner lampshade 5 and the light-homogenizing member 4. Figure 1 In a specific example shown in FIG. 1 , the light blocking member 6 is disposed between the light homogenizing member 4 and the inner lampshade 5. Figure 1 In the cross section shown, a light homogenizing space is constructed between the light blocking member 6 and the inner lampshade 5 and the light homogenizing member 4 , so that light can be projected more evenly from the light homogenizing member 4 toward the inner lampshade 5 , thereby achieving a better uniform light emission effect of the vehicle lamp 100 .

[0042] In addition, the light blocking member 6 can also better limit the size of the light emitting surface of the inner lampshade 5, which is conducive to the light emitted from the inner lampshade 5 being projected to the set area of ​​the outer lampshade 7. For example, the light shielding range of the light blocking member 6 can be designed so that after the light is emitted from the light emitting area of ​​the inner lampshade 5, the outer lampshade 7 can be better prevented from having a dark area. Figure 1 As shown, the lower end of the outer lampshade 7 has a corner a. By designing the light emitting area of ​​the inner lampshade 5, the light emitted from the light emitting area can be radiated to the corner a, thereby preventing the outer lampshade 7 from having a dark area.

[0043] In some embodiments of the present invention, Figure 1As shown, the vehicle lamp 100 further includes a bracket 3, which is disposed between the light emitting element 2 and the light homogenizing element 4. The light inlet of the bracket 3 is opposite to the light emitting element 2, and the light outlet of the bracket 3 is opposite to the light homogenizing element 4. The bracket 3 has a certain reflectivity. When the light emitted by the light emitting element 2 is irradiated onto the bracket 3, the bracket 3 reflects and converges the light according to its geometric shape, forming a relatively concentrated light beam directed forward. By adjusting the design and curvature of the bracket 3, the width (divergence angle) and focusing effect of the light beam can be controlled, thereby realizing long-distance projection of strong light or illumination of a wide area.

[0044] In some embodiments of the utility model, the light-emitting element 2 is an LED lamp. As a modern and efficient solid-state light source, LED lamps have many significant features and advantages and are widely used in various lighting, display, signal indication and other fields. The following are the main features and applications of LED lamps: ① High efficiency and energy saving: The energy efficiency of LED lamps is much higher than that of traditional incandescent lamps and halogen lamps, and the efficiency of converting electrical energy into light energy is high, and higher brightness can be produced with the same power consumption. This not only saves energy, but also reduces operating costs; ② Long life: The service life of LED lamps can usually reach tens of thousands to hundreds of thousands of hours, far exceeding traditional bulbs, reducing the frequency of replacement and reducing maintenance costs. ③ Environmental protection and pollution-free: LED lamps do not contain harmful substances such as mercury and lead, and waste disposal has little impact on the environment. In addition, its low heat generation characteristics reduce the dependence on the cooling system, indirectly reducing energy consumption; ④ Quick response: LED lights start quickly, do not require preheating time, and reach full brightness instantly, which is suitable for occasions that require fast switching or frequent dimming; ⑤ Good stability: LED lights are impact-resistant and shock-resistant, have good adaptability to voltage fluctuations, have a wide operating temperature range, and are highly reliable; ⑥ Miniaturization and lightweight: LED lights are small in size, light in weight, and easy to integrate into various equipment and designs. They are particularly suitable for lighting scenes with limited space or requiring flexible layout.

[0045] In some embodiments of the present invention, the vehicle lamp 100 further includes a PCB board 1, and a plurality of LED lamps are arranged on the PCB board 1. By arranging a plurality of LED lamps, the illumination brightness of the vehicle lamp 100 can be improved.

[0046] Optionally, the light emission colors of the LED lamps can be different, so that the multiple LED lamps can enable the vehicle lamp 100 to have a variety of different lighting effects, thereby better matching actual road conditions.

[0047] The utility model also provides a vehicle having the vehicle lamp 100 of the above embodiment.
