[0051] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of protection of the present application.
[0052] As shown in the figure, the present application provides a lamp, which can be used for a vehicle, used as a brake light of the vehicle, of course, can also be used as a steering light or other function light of the vehicle, the lamp comprises a lamp shell, a light source and a light guide 300. Figures 1 to 10
[0053] Among them, the lamp shell has a sealed cavity, the lamp shell includes a light shielding area and a light transmitting area 220, the light shielding area cannot pass through the light, and the light shielding area can shield the light, the light can pass through the light transmitting area 220, so that the lamp can emit light.
[0054] The light source is arranged in the sealed cavity, and the light source is opposite to the light shielding area, so that the light source is invisible, and the direct light of the light source after emitting light forms a direct light area, which is located in the light shielding area, so as to avoid the direct light of the light source from leaking out.
[0055] The light guide 300 can be a light guide strip, arranged in the sealed cavity, the light guide 300 has an incident light surface and an emitting light surface, the incident light surface is opposite to the light source, and the emitting light surface is opposite to the light transmitting area 220, the light emitted by the light source can be incident into the light guide 300 through the incident light surface, reflected by the light guide 300 and then emitted through the emitting light surface, and finally emitted to the outside of the lamp through the light transmitting area 220, so as to realize the light emission of the lamp. In this way, the light source realizes the lighting effect of the whole lamp through the total reflection of the light guide 300.
[0056] In the embodiments of the present application, part of the direct light emitted by the light source falls into the light shielding area of the lamp shell and is shielded by the light shielding area, so as to avoid the direct light of the light source from leaking out, the remaining light emitted by the light source is incident into the light guide 300 and then emitted through the total reflection of the light guide 300, and then emitted through the light transmitting area 220, so as to realize the light emission of the lamp. The light emitted by the light source can improve the uniformity after the total reflection of the light guide 300, so as to improve the optical uniformity of the lamp. It can be seen that the embodiments of the present application can solve the problem of poor light emission uniformity of the lamp in the prior art.
[0057] The structure of the lamp shell has many kinds, in an optional embodiment, the lamp shell can include two parts, one part is made of light shielding material, and the other part is made of light transmitting material, the two parts can be connected to form the lamp shell by bonding, clamping or screw connection.
[0058] In another alternative embodiment, the lamp shell can also be made of light-transmitting material, and a light-blocking coating is applied to a local area or a light-blocking cloth is attached to a local area to form a light-blocking area, and the remaining part of the lamp shell forms a light-transmitting area.
[0059] In a preferred embodiment, the lamp shell can include a mounting shell 100 and a double-color lens 200. The mounting shell 100 can be made of plastic or metal, or other materials, which are not limited in the present application. The mounting shell 100 is used to connect with the vehicle body. The double-color lens 200 is sealingly connected with the mounting shell 100 to form a sealed cavity. At least part of the double-color lens 200 is used to form a light-transmitting area 220. Alternatively, the double-color lens 200 and the mounting shell 100 can be sealingly connected by vibration friction welding, or the double-color lens 200 and the mounting shell 100 can also be sealingly connected by adhesion.
[0060] In this case, the double-color lens 200 has a condensing effect, and the light emitted through the double-color lens 200 can make the lamp have better light emission effect. The lens material is usually brittle, and if the lens is directly connected with the vehicle body, it is difficult to ensure the stability of the connection between the lamp and the vehicle body. Therefore, the mounting shell 100 is connected with the vehicle body to realize the connection between the lamp and the vehicle body and ensure the stable connection between the lamp and the vehicle body.
[0061] The double-color lens 200 can include a first sub-light-blocking area 210 and a light-transmitting area 220. The mounting shell 100 can form a second sub-light-blocking area. The first sub-light-blocking area 210 and the second sub-light-blocking area can jointly form a light-blocking area. Alternatively, the mounting shell 100 can be made of light-blocking materials such as aluminum alloy and stainless steel.
[0062] The double-color lens 200 can form the first sub-light-blocking area 210 and the light-transmitting area 220 in various ways. In an alternative embodiment, the double-color lens 200 can also have a light-transmitting structure layer 230. A light-blocking coating is applied to a local area of the light-transmitting structure layer 230 to form the first sub-light-blocking area 210.
[0063] In another preferred embodiment, the double-color lens 200 can include a light-transmitting structure layer 230 and a light-blocking structure layer 240 which are connected in stack. In the light-transmitting structure layer 230 and the light-blocking structure layer 240, one can form part of the outer surface of the lamp shell, and the other can form part of the inner wall of the sealed cavity. The light-blocking structure layer 240 can be provided with a light-transmitting hole 241. The area of the double-color lens 200 provided with the light-transmitting hole 241 forms the light-transmitting area 220. In this structure, the processing and production of the double-color lens 200 are facilitated.
[0064] Optionally, the material of the light-transmitting structure layer 230 can be white and 100% transparent, such as PMMA (Polymethyl Methacrylate), to ensure the light-transmitting effect, and the material of the light-blocking structure layer 240 can be black and have a light-blocking effect, such as PC (Polycarbonate) + ABS (ABS plastic, Acrylonitrile Butadiene Styrene plastic), so that the light-blocking structure layer 240 has a light-blocking effect and can also block the functional components inside the lamp, such as the light source, to make the light source invisible. Of course, the light-transmitting structure layer 230 and the light-blocking structure layer 240 can also be made of other materials, and the specific materials of the light-transmitting structure layer 230 and the light-blocking structure layer 240 are not limited in the present application.
[0065] Optionally, the light-blocking structure layer 240 can form part of the inner wall of the sealed cavity, and the light-transmitting structure layer 230 can form part of the outer surface of the lamp shell. This arrangement makes the light-transmitting hole 241 located inside the lamp shell, which can better prevent the accumulation of dust, rainwater and other impurities, maintain the cleanliness of the light-transmitting hole 241, and the light-transmitting structure layer 230 can be welded with the mounting shell 100 to form a sealed lamp shell, so that the lamp shell has better sealing effect.
[0066] Optionally, the double-color lens 200 can be processed by using a double-color injection molding device through a double-color injection molding method. Of course, in other embodiments, the light-blocking structure layer 240 and the light-transmitting structure layer 230 can also be connected by adhesion or other methods.
[0067] Along the length direction of the light-transmitting area 220, the length of the light-transmitting area 220 can be greater than the length of the light guide 300, so that the two ends of the light guide 300 along the length direction are respectively opposite to the light-blocking areas. Along the width direction of the light-transmitting area 220, the width of the light-transmitting area 220 can be greater than the width of the light guide 300, so that the two ends of the light guide 300 along the width direction are respectively opposite to the light-blocking areas. For example, the width of the light-transmitting area 220 can be 6 mm, and the width of the light guide 300 can be 8 mm. In this case, it can reduce the problem that the light emitted by the light guide 300 enters the sealed cavity, is reflected by other functional components in the sealed cavity, and then exits through the light-transmitting area 220, thereby improving the light-emitting uniformity of the lamp.
[0068] In a further technical solution, along a visible direction of the light transmission region 220, a projection of the light transmission region 220 can be located within a projection of the light guide 300, the visible direction referring to any visual angle direction through the outer surface of the lamp, in which the light transmission region 220 can be seen. In this case, the problem that the light emitted by the light guide 300 enters the sealed cavity, is reflected by other functional components in the sealed cavity, and then is emitted through the light transmission region 220 can be further reduced, so that the light emitted through the light transmission region 220 is more light reflected by the light guide 300, thereby further improving the light emitting uniformity of the lamp.
[0069] In a further technical solution, at least a part of the light guide 300 can extend into the light transmission hole 241, and the extending part can abut against the inner wall of the light transmission hole 241, that is, the light guide 300 can block the inner side port of the light transmission hole 241 towards the sealed cavity. In this case, the problem that the light emitted by the light guide 300 enters other functional components in the sealed cavity, is reflected by other components, and then is emitted through the light transmission region 220 to cause non-uniform light emission can be avoided.
[0070] There are various ways to install the light guide 300 in the lamp housing, in an optional embodiment, the light guide 300 can be fixed on the mounting shell 100 by adhesion. In another optional embodiment, the light guide 300 can be connected to the mounting shell 100 by screws.
[0071] In a preferred embodiment, the mounting shell 100 can be provided with a mounting groove 110, the light guide 300 can be clamped in the mounting groove 110, one of the groove walls of the mounting groove 110 can be opposite to the light transmission region 220 to form a light blocking wall 113, the light guide 300 can be located between the light blocking wall 113 and the light transmission region 220, and along the direction from the light transmission region 220 to the light blocking wall 113, the projection of the light guide 300 is located within the projection of the light blocking wall 113.
[0072] In this case, the light guide 300 is placed between the light transmission region 220 and the light blocking wall 113, which can reduce the diffusion of the light emitted by the light guide 300 into the area of the sealed cavity far away from the light transmission region 220, so that the light is concentrated on the side of the light blocking wall 113 facing the light transmission region 220, thereby improving the brightness of the lamp and increasing the optical utilization rate.
[0073] In a further technical solution, along the length direction of the mounting shell 100, the light blocking wall 113 can extend from the first end to the second end of the mounting shell 100, and the side edge of the light blocking wall 113 away from the mounting shell 100 can abut against the double-color lens 200 to divide the sealed cavity into a first chamber and a second chamber which are isolated from each other, the light transmission region 220 surrounds part of the first chamber, and the light guide 300 and the light source are located in the first chamber. In this case, the sealed cavity is divided into two chambers which are isolated from each other by the light blocking wall 113, which can further improve the brightness of the lamp and increase the optical utilization rate.
[0074] In order to improve the connection stability of the light guide 300 and the lamp shell, the light guide 300 can include a light guide part 310 and a connecting part 320 protruding from the light guide part 310, the mounting groove 110 can include a groove body 111 and a sub-groove 112, a partial area of the light blocking wall 113 is bent away from the groove body 111 to form the sub-groove 112, the light guide part 310 can be clamped to the groove body 111, and the connecting part 320 can extend into the sub-groove 112.
[0075] The lamp further can include a light guide bracket 400, which can be arranged in the sub-groove 112 and fixedly connected with the groove wall of the sub-groove 112, and the two opposite surfaces of the connecting part 320 can be respectively attached to the light guide bracket 400 and the groove wall of the sub-groove 112, so as to clamp and fix the connecting part 320 between the light guide bracket 400 and the groove wall of the sub-groove 112. In this structure, the light guide part 310 is clamped to the groove body 111, and the light guide 300 is clamped and fixed by the connection of the light guide bracket 400 and the sub-groove 112, so as to double-fix the light guide 300 and improve the connection stability of the light guide 300 and the mounting shell 100.
[0076] Optionally, the light guide bracket 400 and the connecting part 320 can be connected in the sub-groove 112 by screws, or the groove wall of the sub-groove 112 can be provided with a hot riveting column 130, and the connecting part 320 and the light guide bracket 400 can be provided with hot riveting holes, the hot riveting column 130 sequentially passes through the hot riveting holes of the connecting part 320 and the light guide bracket 400, and the fixed connection of the three is realized by hot riveting.
[0077] The light guide 300 can be processed by injection molding, and after processing, the light guide 300 usually has an injection molding port, which can be located at the connecting part 320. In this case, the injection molding port can be blocked by the groove wall of the sub-groove 112 and the connecting part 320, preventing light leakage and forming a light spot, and improving the light output effect of the lamp.
[0078] We know that the light source will generate heat during light emission, and the heat generated by the light source will change the air pressure in the sealed cavity, which may cause safety problems or damage the lamp.
[0079] Therefore, in the embodiments of the present application, the mounting shell 100 can be provided with a breathable hole, which communicates between the outside of the mounting shell 100 and the inside of the sealed cavity, and the breathable hole can be provided with a waterproof breathable film 600, which is a film structure that is breathable but not waterproof. The sealed cavity can be in communication with the outside of the lamp through the breathable hole and the waterproof breathable film 600. In this case, the sealed cavity can flow with the outside air, ensuring that the air pressure in the sealed cavity is within a stable range, preventing safety accidents or damage to the lamp due to changes in air pressure.
[0080] In order to avoid safety accidents or damage of the lamp caused by heat emitted by the light source, the lamp can be provided with a heat dissipation structure 700 in addition to the air holes and the waterproof air permeable film 600 to ensure the air pressure in the sealed cavity. The heat dissipation structure 700 can be made of aluminum or other materials with good heat dissipation performance and is arranged in the mounting shell 100. The heat dissipation structure 700 can include a first part and a second part. The first part can be attached to the functional module provided with the light source, and the second part can be attached to the mounting shell 100. The light source can be an LED, and the functional module provided with the light source can be a PCB (Printed Circuit Board) 810. The light source can be integrated on the PCB 810.
[0081] In this case, the light source is in contact with the mounting shell 100 through the heat dissipation structure 700, and the heat generated by the light source is conducted to the mounting shell 100 through the heat dissipation structure 700. The heat dissipation of the lamp is achieved through the heat conduction between the mounting shell 100 and the external air, which improves the heat dissipation effect of the lamp, further ensures the safety and stability of the structure of the lamp, and prolongs the service life of the lamp.
[0082] The heat dissipation structure 700 can be provided with a hot riveting hole, and the mounting shell 100 can be provided with a hot riveting column 130. The hot riveting column 130 passes through the hot riveting hole and fixes the heat dissipation structure 700 on the mounting shell 100 by hot riveting. In order to facilitate the installation of the heat dissipation structure 700, the mounting shell 100 can also be provided with a positioning column 140. The heat dissipation structure 700 can be provided with a positioning hole or a positioning groove. The positioning column and the positioning hole or the positioning groove are positioned and matched to realize the positioning and installation of the mounting shell 100 and the heat dissipation structure 700.
[0083] In order to realize the lighting and extinguishing of the light source, a driving board 830 can be arranged in the lamp shell. The driving board 830 is used to power the lamp. Optionally, in the case of using the lamp for a vehicle, the driving board 830 can be electrically connected to the power line of the vehicle through the second wire harness 840 to power the lamp. The driving board 830 is also used to receive the lighting signal of the vehicle. The driving board 830 can be electrically connected to the PCB 810 through the first wire harness 820 to drive the PCB 810 in the lamp to start, so that the light source emits light.
[0084] Of course, in other embodiments, the lamp can be provided with a dedicated power supply to power the electrical components of the lamp.
[0085] Optionally, the lighting signal of the vehicle can be transmitted to the driving board 830 through the second wire harness 840, or other wires or wireless communication, etc. The LED circuit board of the lamp is driven to start. The specific way in which the driving board 830 receives the lighting signal of the vehicle is not limited in the application.
[0086] In the case of using the lamp for a vehicle, especially as a brake lamp, in order to make the lamp more eye-catching, the length of the lamp housing can be 950mm-1050mm, for example, 1000mm, and the length of the light transmission area 220 can be 800mm-850mm, for example, 830mm, to achieve the long light emission area effect of the long size lamp.
[0087] When the lamp and the size are large, the number of light sources can be at least two, and at least two light sources can be respectively arranged at both ends of the lamp housing along the length direction of the lamp housing, and correspond to the light incident surfaces at both ends of the light guide 300. The direct light emitted by the light sources at both ends is all directed to the light shielding area of the lamp housing except for being incident into the light guide 300. In this case, by increasing the number of light sources, the light emission effect of the long size lamp is ensured.
[0088] In the case of arranging at least two light sources at both ends of the lamp housing, the number of functional modules integrated with the light sources, that is, the number of PCB boards 810 can be two, and the number of heat dissipation structure members 700 can be two, and the heat dissipation structure members 700 and the functional modules integrated with the light sources are one-to-one correspondingly arranged.
