Description

Technical Field

[0001] The present invention relates to a light-guiding vehicle lamp lens, and more particularly to a vehicle lamp structure which utilizes a light-guiding element to adjust the light output pattern. Background Art

[0002] Automobile (vehicle) lighting is one of the important components of a car. It can provide lighting for the car when it is driving in dim light conditions such as poor light, foggy weather or rainy weather.

[0003] As technology advances, automotive (vehicle) lighting has also undergone significant changes, and the development of automotive lighting is particularly significant in the field of forward lighting, that is, headlights. Headlights have evolved from simple "on / off", single-directional lamps to adaptive lighting solutions, and the development has accelerated significantly since the development of light-emitting diodes.

[0004] In recent years, headlights have changed significantly to meet new requirements such as performance, efficiency, reliability and styling. Halogen bulbs were introduced in the 1960s, which produced a clearer, brighter and more powerful beam of light, providing a longer projection distance. The next step in the development of headlights was high-intensity discharge (HID) bulbs, including xenon and mercury lamps, which greatly increased the light output of headlights and became the preferred technology for some high-end manufacturers. Light-emitting diode bulbs were developed at the beginning of this century to replace high-intensity discharge bulbs such as xenon and mercury lamps. At the beginning, light-emitting diodes did not have much impact on the overall industry of headlights. However, as the technology of light-emitting diodes further developed, the cost and efficiency of light-emitting diode headlights gradually surpassed those of high-intensity discharge headlights.

[0005] A light-emitting diode (LED) is a semiconductor light source that emits light when current passes through it; that is, an electroluminescent semiconductor electronic component in which electrons and electron holes recombine to release energy in the form of photons.

[0006] Light-emitting diodes are a special type of diode. Like ordinary diodes, light-emitting diodes are made of semiconductor chips, and these semiconductor materials are pre-implanted or doped to produce p and n structures. Like other diodes, the current in light-emitting diodes can easily flow from the p pole (anode) to the n pole (cathode), but not in the opposite direction. Two different carriers: holes and electrons flow from the electrodes to the p and n structures under different electrode voltages. When holes and electrons meet and recombine, the electrons fall to a lower energy level and release energy in the form of photons (light).

[0007] The wavelength of the light it emits is determined by the bandgap energy of the semiconductor materials that make up the p and n structures. Since silicon and germanium are indirect bandgap materials, at room temperature, the recombination of electrons and holes in these materials is a non-radiative transition. This type of transition does not release photons, but converts energy into heat energy, so silicon and germanium diodes cannot emit light (they will emit light at very low temperatures, which can only be detected at special angles, and the brightness of the light is not obvious). The materials used in light-emitting diodes are all direct bandgap types, so energy is released in the form of photons. These bandgap energies correspond to light energy in the near-infrared, visible, or near-ultraviolet bands.

[0008] As mentioned above, with the improvement of LED technology, high-power and high-brightness LEDs have been launched one after another, making this type of bulb gradually replace traditional light sources. In addition to being used in lamps designed specifically for LEDs, LEDs can also be made into bulbs compatible with other light sources after adding conversion circuits and related stabilization devices, and installed in lamps with traditional light sources, including headlights used in automobiles (vehicles).

[0009] When driving in a dark environment at night, drivers often turn on their car's high beams to see a wider range, which helps to better understand the road conditions ahead. However, for vehicles driving in the opposite direction of the vehicle with the high beams turned on, the high brightness and strong light of the high beams will make the driver dazzled and unable to see the road conditions clearly, which is prone to traffic accidents. Therefore, special designs are needed to change the light shape of the car lights to adapt to the external environment that needs lighting.

[0010] However, the light emitting diodes of conventional light-guiding headlight lenses usually use light-guiding elements to change the light pattern. However, the conventional technology has a limited range of changing the light pattern. Therefore, a shielding member is provided to directly shield part of the light. This can adjust the light pattern, but it also reduces the light output efficiency of the headlight. It is necessary to increase the power to meet the light brightness requirements. Therefore, the industry needs a light-guiding headlight lens that can effectively adjust the light pattern.

[0011] In view of the above-mentioned problems of the conventional technology, the present invention provides a light-guiding type vehicle lamp lens, which utilizes a light-guiding element to conduct the light of a light-emitting element, and uses a side slope set on the side of the light-guiding element to utilize a reflective surface to reflect part of the incident light to a light-emitting surface, thereby further avoiding a decrease in the overall light-emitting efficiency of the vehicle lamp structure while adjusting the light-emitting light pattern.

[0023] In order to further understand and appreciate the structural features and effects of the present invention, a preferred embodiment and detailed description are provided as follows:

[0024] In view of the above-mentioned problems of the conventional technology, the present invention is a light-guiding vehicle lamp lens, which utilizes a first body of a light-guiding element to gradually reduce the diameter of the first light-emitting surface to a first light-incoming surface to form a first side bevel and a second side bevel, and a second body of the light-guiding element is provided with a second light-incoming surface and a second light-emitting surface, the second light-incoming surface is connected to the first light-emitting surface, and a third side bevel is respectively provided on two sides of the second body, wherein the light-emitting element emits a light ray, and the light ray passes through the first body and the second body in sequence, and the third side bevel is used to reflect part of the incident light ray out of the light-guiding element, thereby avoiding a decrease in the overall light-emitting efficiency of the vehicle lamp structure.

[0025] See also Figure 1A , which is a structural stereoscopic schematic diagram of an embodiment of the present invention. As shown in the figure, this embodiment is a first embodiment. In this embodiment, it is a light-guiding type vehicle lamp lens 1, which includes a light-emitting element 10 and a light-guiding element 20, and these components are arranged corresponding to each other.

[0026] Continuing with the above, in this embodiment, the light-emitting element 10 is a mini light-emitting diode (Mini Light-emitting Diode, Mini LED); the light-emitting diode is composed of a semiconductor chip, and its semiconductor material is pre-implanted or doped to produce a p, n structure. Like other diodes, the current in the light-emitting diode can easily flow from the p-pole (anode) to the n-pole (cathode), but not in the opposite direction. Two different carriers: holes and electrons flow from the electrodes to the p, n structure under the action of different electrode voltages. When holes and electrons meet and recombine, the electrons will fall to a lower energy level and release energy in the form of photons (light). Micro Light-emitting Diode (Micro LED) is a light-emitting diode with a size below micrometers, which can further enhance the brightness of the light-emitting element 10.

[0027] See again Figure 1A Also see Figure 1B as well as Figure 1C , Figure 1B is a schematic top view of an embodiment of the present invention, Figure 1C This is a side view schematic diagram of an embodiment of the present invention. As shown in the figure, in this embodiment, the light-guiding element 20 includes: a first body 22 and a second body 24. The first body 22 is provided with a first light incident surface 222 at one end corresponding to the light-emitting element 10, and a first light emitting surface 224 is provided at the other end of the first body 22, and the diameter of the first body 22 gradually decreases from the first light emitting surface 224 to the first light incident surface 222, a second light incident surface 242 is provided at one end of the second body 24, and a second light emitting surface 244 is provided at the other end of the second body 24, and the second light incident surface 242 is connected to the first light emitting surface 224.

[0028] Continuing from the above, in this embodiment, the diameter of the first body 22 gradually shrinks from the first light emitting surface 224 to the first light incident surface 222, and a first side bevel 225 and a second side bevel 227 are formed on the two sides of the first body 10 in sequence. The first side bevel 225 is connected to the second side bevel 227, and a third side bevel 246 is respectively provided on the two sides between the second light incident surface 242 and the second light emitting surface 244 of the second body 24, and the third side bevel 246 is used to reflect the light emitting element. 10 emits part of the light; in the present embodiment, a first angle θ1 of the first side bevel 225 corresponding to the first light emitting surface 224 is smaller than a second angle θ2 of the second side bevel 227 corresponding to the first light emitting surface 224, and a third angle θ3 of the third side bevel 246 corresponding to the first light emitting surface 224 is larger than the second angle θ2, and the first side bevel 225, the second side bevel 227 and the third side bevel 246 can adjust the angle of the light entering the first body 22 accordingly.

[0029] Continuing from the above, in this embodiment, the first angle θ1 is between 70° and 90°, the second angle θ2 is between 70° and 90°, and the third angle θ3 is between 80° and 95° (e.g. Figure 1B As shown), for example, when the first angle θ1 is 79°, the second angle θ2 needs to be larger than the first angle θ1, so the second angle θ2 is 81°, and the third angle θ3 needs to be larger than the second angle θ2, so the third angle θ3 is 90°, but this embodiment is not limited thereto.

[0030] Continuing from the above, in this embodiment, since the first upper inclined surface 228 is connected to the second upper inclined surface 249, a fourth angle θ4 of the first upper inclined surface 228 and the second upper inclined surface 249 corresponding to the second light emitting surface 244 is between 0° and 5° (eg Figure 1C As shown), for example, the fourth angle θ4 is 3°.

[0031] Continuing from the above, in this embodiment, the first body 22 and the second body 24 are connected to each other to form an integral structure, that is, the first light emitting surface 224 of the first body 22 and the second light incident surface 242 of the second body 24 overlap each other, and the first body 22 and the second body 24 form an integrated structure (such as Figure 1B shown).

[0032] Continuing from the above, in this embodiment, the material of the light guide element 20 is liquid silicone rubber (LSR). Similarly, the material of the first body 22 and the second body 24 included in the light guide element 20 is also liquid silicone rubber (LSR).

[0033] Continuing from the above, liquid silicone rubber is a liquid rubber relative to solid high temperature vulcanized silicone rubber, which has good fluidity, fast vulcanization, is safer and more environmentally friendly, and can fully meet food grade requirements. According to the position of the functional groups (i.e., cross-linking points) contained in the molecular structure, liquid rubbers with functional groups are often divided into two categories: one is that the functional groups are at both ends of the molecular structure, which is called telechelic liquid rubber; the other is that the active functional groups are randomly distributed in the main chain, that is, the so-called ones with functional groups in the molecular structure, which are called non-telechelic liquid rubbers. Of course, there are also those with both intermediate functional groups and terminal functional groups. At present, the focus is on the study of telechelic liquid rubbers. For liquid rubber, chain extenders or crosslinkers with appropriate functional groups should be selected according to the active functional groups it contains.

[0034] Continuing from the above, liquid silicone has excellent transparency, tear strength, resilience, yellowing resistance, thermal stability, water resistance, good air permeability, heat aging resistance and weather resistance. At the same time, it has moderate viscosity and is easy to operate. The product is highly transparent, and it can be seen whether there are defects such as bubbles in the casting material in the mold. The linear shrinkage rate is ≤0.1%, and the size of the replicated product is precise.

[0035] Continuing from the above, liquid silicone can be used for trademarks, products, pacifiers, medical supplies, coating, impregnation and infusion, etc. It is used in molding molds, injection molding processes, cake molds and other silicone products for crystal glue, polyurethane, epoxy resin, etc. It is widely used in the electronics industry as a moisture-proof, shipping, insulation coating and potting material for electronic components, and it has dust-proof, moisture-proof, shock-proof and insulation protection for electronic components and assemblies. If transparent gel is used to pot electronic components, it can not only play a role in shockproof and waterproof protection, but also the components can be seen and the fault of the component can be detected with a probe for replacement. The damaged silicone gel can be potted and repaired again. It can also be used to manufacture molding molds for products made of materials such as gypsum, wax, epoxy resin, polyester resin, polyurethane resin and low-melting-point alloys, and is used for high-frequency embossing of artificial leather, modeling of shoe uppers and soles, manufacturing of arts and crafts, ceramics, toy industry, furniture, replication of household electrical appliance electronic components, molding of gypsum and cement materials, molding of wax products, manufacturing of models, molding of materials, etc. Therefore, liquid silicone can be used correspondingly in the light guide element 20 of this embodiment.

[0036] Continuing with the above, in this embodiment, the light incident microstructure 23 is disposed on the first light incident surface 222 of the first body 22; in one embodiment, the light incident microstructure 23 protrudes from the first light incident surface 222 of the first body 22; in another embodiment, the light incident microstructure 23 is embedded into the first light incident surface 222 of the first body 22 so that the outermost side is the first light incident surface 222.

[0037] See again Figures 1A to 1C As shown in the figure, in this embodiment, a lower portion of the first body 22 of the light guide element 20 is cut flat to form a first flat reflective surface 223, and a lower portion of the second body 24 of the light guide element 20 is also cut flat to form a second flat reflective surface 243, and the first flat reflective surface 223 is connected to the second flat reflective surface 243 to form the same plane, so that the first flat reflective surface 223 and the second flat reflective surface 243 reflect the light of the light emitting element 10.

[0038] Continuing with the above, in this embodiment, an upper portion of the first body 22 of the light-guiding element 20 is inclined upward from the first light-incident surface 222 to the first light-emitting surface 224 to form a first upper inclined surface 228, and an upper portion of the second body 24 of the light-guiding element 20 is inclined upward from the second light-incident surface 242 to the second light-emitting surface 244 to form a second upper inclined surface 249, and the second upper inclined surface 249 is connected to the first upper inclined surface 228 to form the same inclined surface, and the first upper inclined surface 228 and the second upper inclined surface 249 are used to reflect the light of the light-emitting element 10.

[0039] See also FIG. 2A to FIG. 2B , which is a schematic diagram of the microstructure and light path of an embodiment of the present invention. As shown in the figure, in this embodiment, it further includes a light-incident microstructure 23 and a light-exiting microstructure 30. The light-incident microstructure 23 is disposed on the first light-incident surface 222, and the light-exiting microstructure 30 is disposed on the second light-exiting surface 244 of the second body 24 to adjust / filter the light emitted from the light guide element 20. In one embodiment, the light-incident microstructure 23 and the light-exiting microstructure 30 can be formed integrally with the first body 22 and the second body 24 or attached to the first body 22 and the second body 24 with a microstructure film. 4. The present embodiment is not limited thereto. The light emitting element 10 emits a light ray L, which first hits the first body 22 of the light guide element 20. A portion of the light ray L enters the light incident microstructure 23 provided on the first light incident surface 222 of the first body 22. After the light ray L passes through the first light emitting surface 224 of the first body 22, the light ray L enters from the second light incident surface 242 of the second body 24. After the light ray L passes through the second light emitting surface 244 of the second body 24, the light ray L enters the light emitting microstructure 30. Finally, the light ray L is emitted from the light emitting microstructure 30 to the target area.

[0040] Continuing with the above, in this embodiment, another part of the light L enters from the light incident microstructure 23 set on the first light incident surface 222 of the first body 22. After the light L passes through the first light emitting surface 224 of the first body 22, the light L enters from the second light incident surface 242 of the second body 24. The light L is deflected due to its incident angle. The light L is incident on the third side bevel 246 of the second body 24. The third side bevel 246 reflects the light L out of the second light emitting surface 244. After the light L is emitted from the second light emitting surface 244, the light L enters the light emitting microstructure 30. Finally, the light L is emitted from the light emitting microstructure 30 to the target area. The third side bevel 246 is used to reflect the light L with an angle deflected back to the path to achieve the effect of controlling the light type.

[0041] Continuing with the above, in this embodiment, another portion of the light L enters through the light incident microstructure 23 provided on the first light incident surface 222 of the first body 22.

The first side bevel 225 and the second side bevel 227 are used to reflect the light L with the angle deflected back to the path, so as to achieve the effect of controlling the light type.

The light L is deflected due to its incident angle, and the light L is incident on the first upper inclined surface 228 of the first body 22. The first upper inclined surface 228 reflects the light L, so that the light L is incident on the first flat reflective surface 223. The first flat reflective surface 223 reflects the light L, so that the light L is incident on the second light incident surface 242 of the second body 24. The subsequent path is the same as the above embodiment, so it is not repeated here. The first flat reflective surface 223 and the first upper inclined surface 228 are used to reflect the light L back to the path to achieve the effect of controlling the light type.

[0043] Continuing from the above, in the embodiment in which the second flat reflective surface 243 and the second upper inclined surface 249 are provided, the light L is deflected by the second light incident surface 242 of the second body 24 due to its incident angle. The light L is provided with the second flat reflective surface 243 or the second upper inclined surface 249 of the second body 24. The second flat reflective surface 243 or the second upper inclined surface 249 reflects the light L out of the second light emitting surface 244. After the light L is emitted from the second light emitting surface 244, the light L enters the light emitting microstructure 30. Finally, the light L is emitted from the light emitting microstructure 30 to the target area. The second flat reflective surface 243 and the second upper inclined surface 249 are used to reflect the light L back to the path to achieve the effect of controlling the light type.

[0044] Continuing from the above, the first side bevel 225, the second side bevel 227, the third side bevel 246, the first flat reflective surface 223, the first upper bevel 228, the second flat reflective surface 243 and the second upper bevel 249 reflect the light L by total reflection, or the corresponding coated reflective layer reflects the light L, but the present embodiment is not limited thereto.

[0045] Continuing from the above, in one embodiment, the light incident microstructure 23 forms a V-shaped structure (eg Figure 2A as well as Figure 2B shown).

[0046] Continuing with the above, in one embodiment, the light emitting microstructure 30 shields a portion of the second light emitting surface 244. In one embodiment, the light emitting microstructure 30 is disposed in the middle of the second light emitting surface 244.
