Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, specifically a compact automotive lighting optical module. Background Technology

[0002] Currently, the integrated high and low beam modules for automotive lights are relatively long, generally between 130mm and 160mm, and mostly use a direct beam focusing solution. When the length requirement is reduced, the direct beam focusing solution cannot meet the optical design requirements, and the heat resistance requirements also prevent the length from being further reduced.

[0003] With the widespread adoption of electric vehicles today, headlights need to be miniaturized, which also places demands on the miniaturization of the high and low beam modules within them. Conventional modules are too long and not suitable for current automotive use. Furthermore, modules need to be lightweight, and there is a growing trend towards smaller apertures. Modules with large aperture lenses and long longitudinal lengths are no longer suitable for the development needs of current headlights. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a compact automotive lighting optical module, which solves the problem that when the length requirement is reduced, the direct beam solution of the concentrator cannot meet the optical design requirements, and the heat resistance requirement also prevents the length from being further reduced.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a compact automotive lighting optical module, including a heat sink, wherein a low beam circuit board and a high beam circuit board are respectively mounted in the inner cavity of the heat sink via a third positioning post, the low beam circuit board and the high beam circuit board are stepped, and the height of the high beam circuit board is lower than that of the low beam circuit board, a reflector and a condenser are respectively mounted on the surface of the heat sink with screws, and multiple reflector bowls and condenser bowls are respectively provided in the inner cavity of the reflector and the condenser, and a lens assembly is provided at the port of the heat sink;

[0006] The lens assembly includes a lens bracket fixedly mounted on the heat sink port, with a lens fixedly mounted on the port of the lens bracket, and a heat insulation sheet provided in the inner cavity of the lens bracket.

[0007] Preferably, the reflector and the concentrator pass through the surfaces of the low beam circuit board and the high beam circuit board respectively via the first positioning post and the second positioning post and are inserted into the heat sink.

[0008] Preferably, the surfaces of the low beam circuit board and the high beam circuit board are respectively provided with low beam light source and high beam light source, and the reflector bowl and the focusing bowl respectively cover the low beam light source and the high beam light source.

[0009] Preferably, the inner wall of the lens support port is symmetrically provided with buckles, and the surface of the lens is symmetrically provided with slots, and the buckles and slots are mutually positioned.

[0010] Preferably, the surface of the heat insulation sheet has an integrally extended limiting groove, and a positioning block is provided on the side of the lens assembly. The limiting groove is sleeved on the positioning block, and both ends of the heat insulation sheet are installed in the inner cavity of the lens bracket by screws.

[0011] This utility model provides a compact automotive lighting optical module. Compared with the prior art, it has the following advantages:

[0012] Beneficial effects:

[0013] This compact automotive lighting module uses a stepped design for the low beam and high beam circuit boards, replacing the traditional flat low beam and high beam setup. The stepped design reduces the overall longitudinal length of the low beam and high beam, decreasing the low beam back cutoff and overall module length. Furthermore, it replaces the original single or two reflectors with multiple reflector bowls, facilitating the optimization of the low beam pattern distribution. The multiple focusing bowls also optimize the high beam distribution while changing the high beam to enter from below, deflecting the light pattern into the lens. This shortens the module length without changing the high beam back cutoff, ensuring high beam brightness. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figures 1-8This utility model provides a technical solution: a compact automotive lighting optical module, including a radiator 1. A low beam circuit board 3 and a high beam circuit board 7 are respectively mounted on the inner cavity of the radiator 1 via a third positioning post 8. The surfaces of the low beam circuit board 3 and the high beam circuit board 7 are also provided with connectors for connecting to the vehicle's electrical circuitry and are fixedly installed by screws. The low beam circuit board 3 and the high beam circuit board 7 are stepped, with the high beam circuit board 7 being lower than the low beam circuit board 3. A reflector 2 and a concentrator 6 are respectively mounted on the surface of the radiator 1 using screws. The inner cavity is provided with multiple reflector bowls 22 and condenser bowls 62 respectively. The port of the heat sink 1 is provided with a lens assembly 4. The product has a light-collecting system with multiple reflector bowls 22, a condenser system with multiple condenser bowls 62, a heat dissipation system heat sink 1 that conducts and dissipates heat, an optical lens 42 that projects the light collected by the light-collecting system and the condenser system, a low beam circuit board 3 and a high beam circuit board 7 with a light source, a lens bracket 41 that connects the heat dissipation system and the optical lens 42, and a heat insulation sheet 5 that prevents external focusing.

[0037] Secondly, the device uses a stepped design for the low beam circuit board 3 and the high beam circuit board 7, replacing the traditional flat low beam and high beam setup. The stepped design can reduce the overall vertical length of the high beam and low beam.

[0038] By reducing the low beam back cutoff in the module design, the overall longitudinal length of the module is reduced. Furthermore, the original single or two reflectors 2 are replaced with multiple reflector bowls 22, which facilitates the optimization of the low beam distribution. In addition, the multiple condenser bowls 62 condenser 6 optimize the high beam distribution and change the high beam to enter from below, deflecting the light into the lens 42. This shortens the module length without changing the back cutoff length of the high beam, thus ensuring the brightness of the high beam.

[0039] Please see Figures 18-20 The lens assembly 4 includes a lens bracket 41 fixedly installed at the port of the heat sink 1. A lens 42 is fixedly installed at the port of the lens bracket 41. A heat insulation sheet 5 is provided in the inner cavity of the lens bracket 41. Buckles 43 are symmetrically arranged on the inner wall of the port of the lens bracket 41, and slots 44 are symmetrically arranged on the surface of the lens 42. The buckles 43 and slots 44 are engaged with each other. The engagement of the buckles 43 and slots 44 facilitates the positioning and installation of the lens 42. The lens bracket 41 encloses the condenser 6 and the reflector 2 and fits against the reflector 2 to achieve a seal. In this way, the light source emitted by the low beam circuit board 3 and the high beam circuit board 7 is refracted by the reflector 2 and the condenser 6 and emitted through the lens 42 without light leakage.

[0040] Please see Figures 9-11 and Figures 14-16The reflector 2 and the condenser 6 pass through the surfaces of the low beam circuit board 3 and the high beam circuit board 7 via the first positioning post 21 and the second positioning post 61, respectively, and are inserted into the heat sink 1. The surfaces of the low beam circuit board 3 and the high beam circuit board 7 are respectively provided with low beam light source 31 and high beam light source 71, and the reflector bowl 22 and the condenser bowl 62 cover the low beam light source 31 and the high beam light source 71, respectively. The first positioning post 21 and the second positioning post 61 are used for positioning the reflector 2 and the condenser 6. Then, the reflector 2 and the condenser 6 are installed on the heat sink 1 by screws.

[0041] Please see Figures 12-13 The surface of the heat insulation sheet 5 has an integrally extended limiting groove 51, and the side of the lens assembly 4 is provided with a positioning block 45. The limiting groove 51 is sleeved on the positioning block 45, and the two ends of the heat insulation sheet 5 are installed in the inner cavity of the lens bracket 41 by screws. The heat insulation sheet 5 serves to prevent external focusing.

[0042] The installation is as follows: First, the low beam circuit board 3 and the high beam circuit board 7 are positioned and installed in the inner cavity of the heat sink 1 by the third positioning post 8. Then, the low beam circuit board 3 and the high beam circuit board 7 are fixed on the third positioning post 8 by screws. Then, the reflector 2 and the condenser 6 are passed through the surfaces of the low beam circuit board 3 and the high beam circuit board 7 by the first positioning post 21 and the second positioning post 61, respectively, and are inserted into the heat sink 1. Then, the reflector 2 and the condenser 6 are also installed and fixed by screws. At the same time, the reflector bowl 22 and the condenser bowl 62 are set to cover the corresponding low beam light source 31 and high beam light source 71. Next, the limiting groove 51 is inserted into the positioning block 45 for limiting, so that the heat insulation sheet 5 is installed in the inner cavity of the lens bracket 41 by threads. Then, the lens assembly 4 is installed on the heat sink 1 by screws, so that the lens assembly 4 covers the reflector 2 and the condenser 6. Finally, the lens bracket 41 is installed at the port of the lens assembly 4 by the positioning of the buckle 43 and the slot 44.

[0043] When in use, the low beam circuit board 3 and the high beam circuit board 7 are activated respectively. The low beam lamp source 31 on the low beam circuit board 3 emits light, which shines into the multiple reflector bowls 22 set in the reflector 2. Then the light source in the reflector bowls 22 shines into the lens 42. The heat insulation sheet 5 prevents focusing. Then the light source is projected out through the lens 42 to achieve low beam.

[0044] Similarly, the high beam light source 71 on the high beam circuit board 7 emits a light source, which is refracted into multiple condenser bowls 62 set in the condenser 6. The light source in the condenser bowls 62 is then refracted into the lens bracket 41, where the heat insulation sheet 5 prevents focusing. The light source is then projected out through the lens 42 to achieve high beam.
