DETAILED DESCRIPTION
[0032] 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, not all the embodiments.
[0033] Referring to Figures 1-9The application discloses a light path separation type double-light lens vehicle lamp, which comprises a lens support 1 and a heat dissipation lamp body 2 connected in front and back, the lens support 1 is provided with a lens module 3 at the front end, the lens module 3 can finally converge, shape and project the light emitted by each independent light path at the rear, so as to form a light type meeting regulations and lighting requirements, the heat dissipation lamp body 2 is provided with a heat dissipation piece 6 at the rear end, the heat dissipation piece 6 is provided with an LED light source substrate 4, the heat dissipation piece 6 can quickly absorb and dissipate the huge heat generated by a plurality of LED chips on the LED light source substrate 4 during work, so as to prevent the chips from light decay or damage due to overheating and ensure long-term stable work of the vehicle lamp, the upper and lower end faces of the LED light source substrate 4 are respectively provided with an LED low beam light source 41 and an LED high beam light source 42, so as to respectively emit the low beam light upward and the high beam light downward, and the three-dimensional layout of the back-to-back type is the basis for realizing physical separation of the high beam and low beam light paths in space, the low beam light cup 411 and the high beam light cup 421 corresponding to the LED low beam light source 41 and the LED high beam light source 42 are respectively provided with light outlets facing the lens module 3, the low beam light cup 411 and the high beam light cup 421 can be responsible for collecting the light emitted by the corresponding light source and performing preliminary focusing and guiding, so as to accurately project the light to the lens module 3, thereby forming two independent and complete light paths, the heat dissipation lamp body 2 is provided with a direct light source substrate 22 and a light blocking plate 23 for isolating the direct light source on the front end of the heat dissipation lamp body 2, the light blocking plate 23 can be used for isolating and regularizing the light emitted by the direct light source, preventing stray light from interfering with the main light path and ensuring that the direct light spot is neat and clean, the heat dissipation lamp body 2 is further provided with a light source switching mechanism 5 located in front of the LED light source substrate 4, the light source switching mechanism 5 in the application can realize the double-light function through electromagnetic driving, when the arc-shaped light blocking plate 51 is closed, the light path of the LED high beam light source 42 is blocked, when the arc-shaped light blocking plate 51 is in the closed state, i.e. in the low beam mode, the electromagnetic drive is not powered on, the reset spring in the arc-shaped light blocking plate 51 keeps the arc-shaped light blocking plate 51 in the working position, i.e. the closed state, the arc-shaped light blocking plate 51 in the position can accurately block the light path of the LED high beam light source 42 from below, and meanwhile, the light path of the LED low beam light source 41 above is not affected, and the LED low beam light source 41 normally emits light, and the lens forms a low beam light type.
[0034] Specifically, the working mode is as follows:
[0035] 1, low beam mode: the LED low beam light source 41 on the upper end face of the LED light source substrate 4 is lit, and the light is emitted upward, collected and reflected by the low beam reflector cup 411, forming a specific low beam light pattern. At the same time, the light source switching mechanism 5 is in the closed state, that is, the arc-shaped light shield plate 51 is located in the closed position. This position accurately shields the light from the high beam light path and allows the low beam light to pass through, and finally projects a low beam with clear bright-dark cut lines through the lens module 3, ensuring that the driver of the vehicle in front will not be dazzled.
[0036] 2, high beam mode: when high beam illumination is needed, the LED low beam light source 41 can continue to be lit, and at this time, the LED high beam light source 42 on the lower end face of the LED light source substrate 4 is lit, and the light is emitted downward, collected and reflected by the high beam reflector cup 421, and then shot to the lens module 3. At this time, the arc-shaped light shield plate 51 of the light source switching mechanism 5 can be in the open state, that is, it no longer shields the high beam light path, so that the light of the low beam light path and the high beam light path passes through the lens module 3 at the same time, and is superimposed to form a high beam with higher brightness, longer illumination distance and wider range.
[0037] 3, light supplementing mode: the direct light source substrate 22 can be activated synchronously in low beam mode or high beam mode, and the light emitted by it is directly shot to the lens module 3 after being regularized by the front light shield plate 23, forming a concentrated high-brightness light spot, greatly enhancing the central illuminance and penetration of the vehicle lamp.
[0038] Also, in the utility model, the traditional double light lens vehicle lamp arranges high beam and low beam light sources side by side in a two-dimensional plane, and the application arranges the LED low beam light source 41 and the LED high beam light source 42 on the upper and lower surfaces of the same substrate by adopting the "double-sided substrate", realizes the complete separation of the high beam and low beam paths in the Z-axis space, and this three-dimensional layout reduces the cross interference between the light paths in physics.
[0039] In addition, on the premise that high-quality basic high beam and low beam have been realized, the application can extend forward through the direct fixed block 21, successfully integrating a third independent direct light path. This light path is not a simple functional superposition, but a performance enhancement module specially used to improve the limit brightness of the high beam center, realizing the perfect combination of "basic illumination" and "performance enhancement", and greatly expanding the upper limit of the performance of the vehicle lamp.
[0040] Moreover, the LED low beam light source 41 and the LED high beam light source 42 and the direct light source each have independent reflection / direct reflection channels, and only share the front lens, which can effectively avoid the light beam crosstalk caused by the traditional "single light axis + single light shield plate".
[0041] Finally, the application integrates three light sources and their light paths in a compact linear structure, and directly sets the LED light source substrate 4 on the large heat sink 6, thereby realizing efficient unified management of multiple heat sources. This design realizes maximum functionality and reliability in limited space, and is very suitable for modern car designs with strict space requirements.
[0042] Further, in the embodiment, as shown in Figure 2 and Figures 4-8 , the light shield plate 23 is a U-shaped structure, and each LED direct light source lamp bead 221 on the direct light source substrate 22 is provided with a light shield plate 23 in front of it, so that the light emitted by each LED direct light source lamp bead 221 is constrained and regularized from left, right and top by the exclusive U-shaped light shield plate 23 in front of it. This design can effectively collect light and completely prevent horizontal light interference between lamp beads, ensuring that the light emitted by each lamp bead is pure and concentrated to the lens module 3.
[0043] In detail, in the utility model, the U-shaped structure of "one lamp bead and one shield plate" can establish an independent "optical tunnel" for each LED direct light source lamp bead 221, and this design can effectively isolate the light emitted by adjacent lamp beads, avoid mutual superposition and halo caused by light diffusion, and ensure that the edge of the direct light spot is sharp and the center brightness is concentrated. At the same time, through three-sided blocking, the originally scattered invalid light to the side is reflected back to the correct light path, improving the utilization rate of light and making the direct light more powerful.
[0044] Further, in the embodiment, as shown in Figure 2 and Figures 4-8 , the direct light source substrate 22 is integrated with N LED direct light source lamp beads 221, and the light emitted by all LED direct light source lamp beads 221 can be accurately regularized by the exclusive light shield plate 23 in front of it, ensuring that the light is pure and concentrated to the lens, and outputting standard high beam lighting effect, wherein N≥1.
[0045] In detail, in the embodiment, when N=1, the LED direct light source lamp bead 221 is arranged in the middle of the direct fixed block 21, at this time, the single high-power lamp bead is arranged in the middle, and a concentrated core light spot can be generated. When N=2, the LED direct light source lamp beads 221 are symmetrically arranged on the left and right sides of the direct fixed block 21, at this time, the two lamp beads are symmetrically arranged, and a wider and more uniform central bright area can be generated, and at the same time, the local heat accumulation of the single lamp bead can be effectively avoided, the larger heat dissipation area is utilized, the heat distribution is more uniform, and the reliability is higher. When N>2, the LED direct light source lamp beads 221 are distributed at equal intervals on the direct fixed block 21, and a wide and high-brightness central light band can be formed, and at the same time, it can be ensured that when multiple lamp beads work, the heat can be evenly diffused along the direct fixed block, and the hot spot is prevented, and the equal interval also provides a basis for optical uniformity.
[0046] In detail, in the embodiment, the number and layout of the lamp beads are changed, and different performance grade vehicle lamp products can be derived, the differentiated needs of the host factory for different vehicle positioning and costs are met, the design universality and market adaptability are greatly improved, and the application can also ensure switching from a single lamp bead to multiple lamp beads, and the optical output can be perfectly superimposed on the basic high-low light path.
[0047] Further, in the embodiment, as shown in Figure 2 , Figure 4 , Figure 6 and Figure 8 , when N≥2, the light blocking plates 23 in front of the LED direct light source lamp beads 221 are connected as a whole structure, when installing, the operator only needs to align and fix once, and the light blocking installation of all LED direct light source lamp beads 221 can be completed, avoiding the tediousness of installing and debugging one by one, the assembly efficiency is significantly improved, and the risk of human error is reduced. At the same time, the whole structure also ensures that the relative positions of all light blocking plates 23 are fixed and accurate, which ensures that the light paths emitted by multiple LED direct light source lamp beads 221 can be parallel and neat to the lens, forming a clear and uniform superimposed light spot, avoiding the light path scattering or light spot distortion caused by the installation deviation of a single light blocking plate.
[0048] Further, in the embodiment, as shown in Figure 4 , Figure 7 and Figure 8As shown, the direct fixed block 21 is also provided with a heat pipe 222, the evaporation end of the heat pipe 222 is attached to the direct light source substrate 22, and the condensation end of the heat pipe 222 is attached to the heat dissipation lamp body 2. When a high-power direct light bead is used, concentrated heat will be generated in the small volume of the direct fixed block 21, and the heat dissipation capacity of the traditional solid is limited, which is easy to form a high-temperature hot spot. The heat pipe 222 is used to dissipate heat from the direct light source substrate 22, which can ensure that the direct light source maintains stable output of high brightness for a long time without significant heat attenuation, thereby improving the reliability and service life of the direct light source and the entire vehicle lamp system.
[0049] Further, in the embodiment, as shown in Figure 2 The direct fixed block 21 is provided with a vortex fan heat dissipation member 211 located at the rear end of the direct light source substrate 22, which can generate high-speed airflow directly blowing to the rear end of the direct light source substrate 22 to achieve forced convection heat dissipation, so as to quickly take away the accumulated heat and ensure that the LED junction temperature is always suppressed within a safe and low light decay range. This makes the vehicle lamp maintain the peak brightness of the central spot without falling even in the case of long-time opening of the enhanced high beam. At the same time, the vortex fan heat dissipation member 211 is built into the direct fixed block 21, which can achieve the purpose of heat dissipation without occupying or increasing the external profile of the vehicle lamp.
[0050] Further, in the embodiment, as shown in Figure 2 and Figure 4 The heat dissipation member 6 includes a fin heat sink 61 fixed on the rear end of the heat dissipation lamp body 2 and a heat dissipation fan 62 arranged at the rear end of the fin heat sink 61, and the LED light source substrate 4 is installed on the fin heat sink 61. The surface of the fin heat sink 61 is provided with a flat mounting surface for mounting the LED light source substrate 4 therein, which realizes the direct connection of the "heat source" and the "cold source", avoids the accumulation of thermal resistance and efficiency loss caused by long-path heat conduction. At the same time, when the vehicle is running at low speed, stationary or the ambient temperature is very high, the "wind effect" and natural convection will be weakened or ineffective. The heat dissipation fan 62 can actively generate high-speed and directional airflow to forcibly blow or suck through the gap of the fin heat sink 61, ensuring that there is sufficient air to take away heat under any working condition, thereby improving the reliability and life of the vehicle lamp.
[0051] Further, in the embodiment, as shown in Figure 2As shown, the heat dissipation lamp body 2 comprises a front and rear lamp body main body 24 and a lamp body rear cover 25, the front end of the lamp body main body 24 is provided with a first fixed support 241 connected with the lens support 1 and both sides are provided with baffles 242, the first fixed support 241 can provide a specific and strong connection point for realizing the butt joint of the heat dissipation lamp body 2 and the lens support 1, and the main connection stress can be concentrated on the strengthened support instead of the thin shell, thereby ensuring the long-term stability of the whole vehicle lamp front optical system in the vehicle vibration environment. The heat dissipation piece 6 is arranged at the rear end of the lamp body main body 24, the front end and the left and right ends of the lamp body rear cover 25 are designed as openings, which can directly cover the lamp body main body 24 from the rear and the side to realize rapid packaging. The two baffles 242 are respectively arranged on the left and right ends of the lamp body rear cover 25, and the front end of the lamp body rear cover 25 is fixed on the first fixed support 241. The assembly mode of the lamp body main body 24 and the lamp body rear cover 25 adopted in the application can make all components in the vehicle lamp be installed on the lamp body main body 24 for adjustment and test first, and then the lamp body rear cover 25 is covered to complete the final sealing, which avoids the complex assembly process of traditional screwing from multiple directions, realizes the simple assembly of "quickly covering and front end fixing". At the same time, it also means that in the after-sales service, the whole vehicle lamp does not need to be disassembled, and the internal maintenance can be carried out only by opening the rear cover from the rear, which greatly reduces the maintenance difficulty and cost.
