Description

Technical Field

[0001] The utility model relates to the technical field of lighting modules, in particular to a high beam module for accompanying lighting. Background Art

[0002] In modern automotive headlight design, high and low beam modules are widely used to generate different light beams to meet the different needs of low and high beams during driving. With the continuous development of LED (Light-Emitting Diode) technology, the size of vehicle headlight high and low beam modules has gradually decreased. At the same time, changes in vehicle headlight design and space constraints have led more and more automakers to require smaller and smaller module openings. However, as the size of the light-emitting opening decreases, the module's luminous efficiency is severely affected. In this context, due to the gradual improvement of automotive component evaluation standards and the continuous improvement of customer requirements for vehicle headlight performance, there is an urgent need to improve the utilization efficiency of LED luminous flux.

[0003] To meet these needs, the design of the high and low beam modules has evolved from an original circular design to a current square design, and then to a strip shape after further reducing the thickness to better accommodate space and lighting requirements. With separate high and low beam modules, typically, during driving, only the low beam is illuminated, while the high beam is not. This design often results in a visual effect of "lighting up in one section and darkening in another." Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features therein can be combined with each other.

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0030] A high beam module that lights up Figures 1 to 4 Shown, including,

[0031] A high-beam light source 1 is provided on the light source circuit board 3 along a first direction and emits a first emergent light;

[0032] Along with lighting the light source 2, a second outgoing light is emitted along the first direction on the light source circuit board 3;

[0033] The condenser 4 is provided on the light-emitting side of the high-beam light source 1 and the accompanying lighting light source 2, and refracts the first outgoing light and the second outgoing light respectively to form a first refracted light and a second refracted light;

[0034] The lens assembly 5 is provided on the light-emitting side of the condenser 4 . The first refracted light passes through the lens assembly 5 to form a high beam light shape, and the second refracted light passes through the lens assembly 5 to form a follower light.

[0035] Specifically, the utility model provides a high beam module with accompanying lighting, in which the high beam light source 1 and the accompanying lighting light source 2 are arranged on the same light source circuit board 3; the concentrator 4 integrates the high beam refraction and the accompanying lighting light refraction, and refracts the first outgoing light of the high beam light source 1 and the second outgoing light of the accompanying lighting light source 2 respectively to form a first refracted light and a second refracted light. The first refracted light passes through the lens assembly 5 to form a high beam light shape, and the second refracted light passes through the lens assembly 5 to form an accompanying light, thereby ensuring the optical performance of the module. When the low beam and high beam are working, the visual effect of the module can maintain a uniform lighting state, avoiding the risk of dark areas and glare.

[0036] In a preferred embodiment, the concentrator 4 includes:

[0037] A high-beam optical structure 41 is arranged along the first direction, and the high-beam optical structure 41 and the high-beam light source 1 are at the same horizontal height;

[0038] The accompanying lighting optical structure 42 is arranged along the first direction, and the accompanying lighting optical structure 42 and the accompanying lighting light source 2 are at the same horizontal height;

[0039] The optical structure 42 is provided with a square concave-convex pattern when it is illuminated.

[0040] Specifically, the accompanying lighting optical structure 42 is located below the high beam optical structure 41, and the accompanying lighting light source 2 is located below the high beam light source 1. After the light is deflected and illuminated through the lens, it shines toward a position above 5 degrees from the horizontal, avoiding the glare caused by the superposition of light and the three zones of low beam and low beam, which affects regulations. It realizes that when the low beam is lit, the high beam module is also lit, which ensures both beauty and safety.

[0041] After the light is gathered, it is evenly dispersed through the concave-convex pattern on the accompanying lighting optical structure 42 and then illuminates the lens assembly 5, forming accompanying lighting, so that when the low beam is lit alone, the high beam lens is lit without affecting the effect of the low beam regulation.

[0042] In a preferred embodiment, the lens assembly 5 includes a plurality of sequentially connected light incident curved surfaces 51 and a light emitting curved surface 52 provided on the light emitting side of the light incident curved surface 51, thereby ensuring the overall simplicity of the appearance and achieving the effect of splicing multiple focal lenses, so that a single high-beam concentrator can converge light at a focal point, thereby improving the utilization of light efficiency.

[0043] Specifically, the lens assembly 5 is composed of small lenses with multiple focal points, which greatly reduces the opening size of the upper and lower lenses. A light shape is formed by a single small lens and a corresponding focusing optical structure. Finally, multiple light shapes are combined to form an overall high beam light shape, ensuring the optical performance of the module.

[0044] More specifically, the number of light incident curved surfaces 51 is set to 5-7. In this embodiment, 6 light incident curved surfaces 51 are taken as an example. The concentrator 4 refracts the first outgoing light emitted by the high beam light source 1 and the second outgoing light emitted by the accompanying lighting light source 2 to form a first refracted light and a second refracted light. The first refracted light and the second refracted light pass through the light incident curved surface 51 and the light exiting curved surface 52 to form a corresponding high beam light shape and achieve an accompanying lighting effect.

[0045] When the opening size becomes narrower, higher-performance optical effects can be achieved, and in the low-beam state, the high-beam module can achieve uniform accompanying lighting without generating glare.

[0046] In a preferred embodiment, a lens holder 6 is further included. The lens holder 6 is arranged between the concentrator 4 and the lens assembly 5 , and a plurality of light-blocking fins 7 are provided on the lens holder 6 .

[0047] Specifically, the high-beam optical structure 41 and the accompanying lighting optical structure 42 are integrated into one body, which greatly reduces the space of the lens assembly 5 and the lens bracket 6.

[0048] In a preferred embodiment, the light-blocking fin 7 includes a supporting portion 71 and light-blocking portions 72 provided on both sides of the supporting portion 71 .

[0049] Specifically, the lens holder 6 has a light-blocking fin 7 between the lens assembly 5 and the concentrator 4. The presence of the light-blocking fin 7 allows the light converged by the concentrator 4 to enter the lens surface corresponding to the focus, preventing large-angle light from entering the adjacent lens to form stray light.

[0050] In a preferred embodiment, the supporting portion 71 is cylindrical, and the light blocking portion 72 is provided with wavy patterns.

[0051] Specifically, the middle part of the fin is a cylindrical structure, and the two sides are corrugated patterns. The cylindrical structure plays a supporting role to prevent the fin from being too thin and deformed, and the wavy pattern can weaken the reflected stray light formed by light shining on the side walls.

[0052] In a preferred embodiment, a heat sink 8 is further included, and the heat sink 8 is arranged on the back side of the light source circuit board 3 .

[0053] Specifically, the light source circuit board 3 generates heat during operation. The heat sink 8 helps dissipate the heat from the circuit board by increasing the heat conduction area, thereby preventing the circuit board from overheating and maintaining the stability of the power supply and other components.

[0054] Too high a temperature may reduce the efficiency of the light source or even damage circuit components. The heat sink 8 can effectively reduce the temperature and prevent thermal damage.

[0055] In a preferred embodiment, first fixing holes 9 are provided on both sides of the concentrator 4, and the concentrator 4 is fixed to the heat sink 8 through the fixing assembly 10 passing through the first fixing holes 9;

[0056] The lens holder 6 is provided with a second fixing hole 11 , and the lens assembly 5 is fixed to the lens holder 6 via the fixing assembly 10 passing through the second fixing hole 11 .

[0057] Specifically, the fixing component 10 is a screw, and the concentrator 4 is fixed to the radiator 8 by passing through the light source circuit board 3 through the screw, which saves space, makes the overall structure square, and facilitates space utilization, realizes the convergence of the light emitted by the high beam light source 1 and the accompanying lighting light source 2, and forms the high beam light shape and accompanying lighting effect through the lens component 5.

[0058] More specifically, the fixing assembly 10 may also be a quick-lock buckle, which is a connection method that fixes two components through a snap-on and release mechanism, which helps the concentrator 4 and the lens assembly 5 to be easily installed or removed.

[0059] The fixing component 10 can also use an internal threaded pin. The design of the internal threaded pin can avoid directly threading in the circuit board or other structures, and can also make the fixation more secure and facilitate repeated disassembly.

[0060] The concentrator 4 of the present invention is designed to converge or diverge the light emitted by the high-beam light source 1 and the accompanying lighting light source 2 by screwing the light source circuit board 3 to the heat sink 8. The lens assembly forms a high-beam beam pattern or an accompanying lighting effect through the lens assembly. The lens assembly 5 is positioned relative to the lens holder 6 using a positioning post and then secured with screws to form a lens holder subassembly. Once the lens assembly 5 is mounted on the lens holder 6, it is then screwed to the heat sink 8 to complete the overall assembly.

[0061] The utility model has a compact structure and is easy to install, thereby reducing the overall volume of the module and lowering the production cost; at the same time, it realizes a high-performance high-beam function while realizing an ultra-thin structure; at the same time, it satisfies the effect of evenly lighting the high-beam module when the low-beam is on, and can meet the low-beam regulations and avoid the risk of glare.

[0062] The above description is only a preferred embodiment of the present invention and does not limit the implementation method and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
