Description

Invisible Reflective Lighting Technology Fields

The invention relates to a concentrating lighting device, in particular to a lighting device for vehicles such as automobiles, tractors and motorcycles. Background technique

Lights bring light to people, especially when various vehicles drive at night and cannot do without the lighting of lights. However, most of the lighting lamps currently used are direct lighting, that is, the light source directly shines on the illuminated object (or road surface) after being reflected by a reflector. The disadvantage is that the light also irritates the driver or other personnel If the eyes are clear, it may cause the other party to be dazzled. Although the use of far and near light control can reduce the glare of some light, it still cannot solve the problem of glare of the light. At the same time, it increases the burden of manipulation. Both sides of the car, pedestrians, and cyclists may cause glare, making it difficult to see the road conditions, and easily causing traffic accidents, such as: collisions, rollovers and other vicious accidents. Therefore, the current car light lighting device urgently needs to be improved to reduce the occurrence of accidents. After retrieving the patent data, there are many new technical solutions for this type of lighting device, but they are not ideal, such as:

CN85203634U. CN2058888U, CN2150098Y, all are to utilize polarized light technology to solve the glare problem of light, its shortcoming is that this technology needs supporting device, and the driver also needs to be equipped with special-purpose glasses, uses polarizing film, causes the light brightness of lamp to weaken etc., so , it is inconvenient to use, and its practical value is low; Another example: CN86203791U, CN8720578U, CN2083122U, these three kinds of schemes all adopt the refraction cover in the form of shutters, although the problem of glare is solved, if the cover is installed outside the lampshade, the vehicle will be damaged for a long time. Operation, especially in windy, frosty, rainy and snowy weather, is likely to make the reflective surface of the refractor dirty, weaken the reflected light, and affect the brightness of the lighting. If it is installed in the lampshade, it is difficult to manufacture. In addition, the principle of the device is to reflect the light above the center line of the lamp to below the center line, and its installation position should not be too low, otherwise, it will affect the irradiation distance and other factors. Therefore, these several technical solutions also have certain shortcomings, which are unfavorable for popularization and application. For this reason, it is urgent to provide a lighting device that can solve the glare problem of lights and has high practical value.

Figure 5 is a schematic diagram of the invisible reflective lighting device with an integrated adjustable mechanism of the present invention; Figure 6 is a schematic view of the invisible reflective lighting device with a bolt adjustable mechanism of the present invention; Figure 7 is a schematic view of the present invention with a push-pull three-pole adjustable mechanism A schematic diagram of an invisible reflective lighting device; FIG. 8 is a schematic diagram of an invisible reflective lighting device with a spring lever telescopic adjustable mechanism in the present invention; FIG. 9 is a schematic view of a invisible reflective lighting device with a wedge sliding adjustable mechanism in the present invention; The invention has a structure of a hidden reflective lighting device with a tilt-adjustable mechanism of a reflector. Firstly, it will be explained in conjunction with Figure 1: reflector 1, which is an ordinary mirror, can be flat or curved, and the most widely used should be a flat mirror. This figure is an example of a flat mirror. The reflector 1 is one of the characteristics that distinguish other lighting devices, and is installed on the opposite side of the light source; parabolic reflector 2, auxiliary filament 3, main filament 4', wiring board 5, housing 6, lampshade 7, lamp ring 8, These The components are basically the same in structure, function and material as the existing lighting device (lamp), and can be of various types, referred to as the light source lamp, which belongs to the prior art, so it will not be introduced in detail; high beam 9, low beam 10, they The light reflected by the reflector 1; the illuminated object 11 refers to the road or other illuminated objects; the mounting base (not shown in the figure), which is a part of the lighting device and other components installed as a whole, can be a screw or other types.

The feature of this invisible reflective lighting device is that it does not direct the light emitted by the light source lamp (the light emitted by the main filament 4 and the auxiliary filament 3 through the reflective mirror 2 to reflect the concentrated light) to the illuminated object 11 first, Instead, it is sealed in the housing 6 and shoots to the reflector 1 first. After being reflected by the reflector 1, the light beams 9 and 10 pass through the lampshade 7 at a certain oblique angle and then illuminate the object 11, which follows the law of reflection. Since the reflector 1 and the light source lamp are integrated, the integrated invisible reflective lighting device shown in Fig. 1 is called. It can be seen from Figure 1 that, in addition to the reverse installation of the light source lamp in the housing 6, compared with the existing lighting device (lamp), an additional inclined reflector 1 is added, and the lampshade 7 is not installed on the parabolic reflector. 2, but installed below it, so the structure of this invisible reflective lighting device is not complicated compared with existing car lights.

In addition, in addition to adding a reflector to the invisible reflective lighting device, when the reflector and the light source lamp are manufactured or installed, the reflector and the light source lamp must have a certain inclination angle α, and the inclination angle α can be between 2°-75° Any angle in the range of ° will do, but any angle in the range of 10° -35° is optimal. According to its inclined type, it can also be made into the following types.

Fig. 2 is an inclined light source lamp, Fig. 3 is an inclined reflector, and Fig. 4 is an inclined light source lamp and a reflector, so it is called a double inclined type. Their structures are all the same, except that their inclined parts are different, so the part names are described only in Figure 2 as an example, and the other drawings are basically the same, and will not be described again. Lampshade 7, it is made of astigmatism glass; Lamp circle 8, it is fixed lampshade 7; Housing 6, it is the basis that installs whole lighting device parts; Light source lamp 4, it is the light source of this lighting device, it can be Various modern lighting devices (or lighting lamps); the light source lamp mounting base 15, which is a part that connects the light source lamp 4 and the housing 6, can be connected by bolts and nuts, or by other connection types ; The lamp line 12 is the power cord of the light source lamp 4; the back cover 13 forms a closed space with the housing 6, and the two are connected by a loose-leaf (no serial number mark on the figure), and can be opened and closed freely. A reflector 1 is installed on the cover; reflector 1, which is a key component of the lighting device, is required to be made of a material with good reflectivity, or it can be a general reflector, and its function is to reflect the light emitted by the light source lamp After this reflection, then illuminate the object 11 through the lampshade 7; the lock nut 14 is used for fixing Fixed rear cover 13; beam 10, which is the light reflected by reflector 1; object 11 to be illuminated refers to road or other objects to be illuminated.

The working principles and structures of the three forms shown in Fig. 2, Fig. 3 and Fig. 4 are basically similar, and their working principles are the same as those shown in Fig. 1. The difference is that the light source lamp 4 is an integral prior art Lighting lamp, it can be various types of existing lighting lamps, its biggest advantage is that it is easy to manufacture, can not change the production line of the manufacturer, saves development and production funds, if the light source lamp burns out, only need to replace the light source lamp or The internal light bulb is enough, it does not need to be replaced as a whole once it is burnt out as in Fig. Characteristic, can also manufacture other appearance shapes with different shapes, do not give an example here, in a word, its appearance shape can be various, can manufacture not only simple but also beautiful shell shape according to different vehicle models and needs.

Fig. 5 is a schematic diagram of an invisible reflective lighting device with an adjustable mechanism in the present invention. An adjustment screw 16 is provided on the housing 6. It has a screw thread at one end and is connected with other parts through a nut. It is a spherical shape that matches its seat, which is connected to the housing 6, and a movable support 17 is provided at the lamp circle 8.

Adjusting the irradiation distance is realized by turning the nut on the adjusting screw 16, that is, tightening the nut, raising the front end of the lighting device, making the whole housing 6 rotate backward around the movable support 17, and raising the far and near beams 9 , The irradiation angle of 10 increases the irradiation distance, otherwise it reduces the irradiation distance. The adjustment method shown in Figure 5 is to adjust the overall tilt position of the lighting device to achieve the purpose of adjusting the irradiation distance, and it can also be adjusted in other ways. Below, several adjustment options are described:

Figure 6, Figure 7, Figure 8, Figure 9, and Figure 10 are all five schemes of a split adjustment structure, that is, the light source lamp 4 and the reflector 1 are manufactured and installed separately. The first one is that the light source lamp is inclined type, and the latter one is that the reflector is inclined type. Its irradiation principle is the same as that in Figure 5, so it will not be described one by one. The different parts will be described below.

Comprise as shown in Figure 6: lower lampshade 7b (identical with aforementioned lampshade); Upper lampshade 7a, it can be a false lampshade and plays adornment effect, also can be identical with lampshade 7b; Lamp circle 8, housing 6 are identical with aforementioned; The function of the adjustment mechanism 18 is to adjust the inclination angle of the light source lamp 4, so as to adjust the distance of the irradiation distance. It is a bolt type, which can change the inclination angle of the light source lamp 4 by raising or lowering the position of the earmuffs at the rear end of the light source lamp 4 (there is no net number mark on the figure) on the bolts, that is, to raise the position of the earmuffs , the angle of inclination of the light source lamp 4 is large, and the distance of its irradiation is near, otherwise, the farther; the light source lamp 4, which is the light source of the lighting device, can be a variety of modern lighting lamps, and it is different from Fig. 5 The same is to manufacture separately, the advantage of this is that the original production line can not be changed, and it is more convenient to damage and repair during use; the refractor 19, it is to block the light of the light source lamp 4 from scattering in other directions; the lamp line 12, it is the light source The power cord of the lamp 4; the back cover 13, which forms a closed space with the housing 6, the two are connected by a loose leaf (no serial number mark), and can be opened and closed freely, and a reflector 1 is installed on the back cover; The reflector 1 is the same as the previous one; the locking nut 14 is used to fix the back cover 13; the movable support 21 is used to connect the light source lamp 4 to the housing 6, so that the light source lamp 4 can be made around its support Corresponding rotation; the light channel 20, which is made of reflective material, can also be in the form of a reflector, the light beam 10 can pass through the channel, and further play a role in concentrating light; the light beam 10 is the light reflected by the reflector 1; The subject 11 is the same as that described above.

Shown in Figure 7 includes: lampshade 7, lamp ring 8, housing 6, light source lamp 4, movable support 21, lamp line 12, back cover 13, reflector 1, light channel 20 (these are identical with preceding description) , the adjustment nut is fixed on the housing 6, the function of the adjustment assembly 18 is the same as that of the previous fan 18, the difference is that the structure is different, it is a three-push push-pull type, in which the horizontal rod (no serial number mark) is matched with the adjustment nut, The other end is joined with the joints of the upper and lower inclined rods, and the upper and lower inclined rods can be rotated on their joints, and the angle between the upper and lower inclined rods (without serial number marks) can be adjusted by twisting the horizontal rods, that is to say, by pushing and pulling function, can change the inclination angle of the light source lamp 4, thereby achieving the purpose of adjusting the distance of the irradiation distance; the locking buckle 14', which replaces the locking nut 14 in Figure 2, has the same function. It is commonly used and mainly consists of hooks, buckles, movable pins and handles.

Fig. 8 is an invisible reflective lighting device provided with a spring rod telescopic adjustment assembly, the structure of which is the same as that of Fig. 6 or Fig. 7, the difference is the adjustment assembly. Therefore, only the adjustment components are shown, and Fig. 9 is also similar to Fig. 8. First illustrate with Fig. 8, adjusting screw 16 it is the bolt that has screw thread, outer cover 22, there is nut and adjusting screw rod 16 to match at the upper end, and spring 23 and adjusting screw 24 are installed inside; Spring 23, plays recovery function; Adjust pole 24, its upper end is installed in the outer cover 22, and is pressing the end of spring 23, and the lower end is connected with the shell of light source lamp 4 by earmuff 25; Movable support 21, it is movable pin type. The working principle of the adjustment assembly is: by tightening the adjustment screw 16, the adjustment rod 24 will be pushed and the spring 23 will be compressed, so that the adjustment rod 24 will protrude outwards, and the light source lamp 4 will be pushed to surround its movable support through the earmuffs 25. Seat 21 rotates, and the front end is inclined downwards, has changed the inclination angle of light source lamp 4 and reflector, unscrews adjustment knob 16 ', and its effect is opposite, thereby reaches the purpose of adjusting the distance of irradiation.

Fig. 9 is a wedge sliding adjustment assembly, which includes an adjustment lever 16 ", with a number of corresponding positioning holes on one end, passing through the pin seat 26 and the housing 6, and the other end is connected with the wedge 28. light source lamp The housing is provided with chute 27, which is slidably connected with the top of the wedge, and the bottom of the wedge is slidably connected with chute 29, and the adjustment rod between the housing 6 and the wedge 28 is covered with spring 23. The adjustment principle is: by pulling the adjustment lever 16" outward, the wedge 28 first compresses the spring 23, and then slides outward along with the adjustment lever 16" in its chute 27, 29, since the wedge 28 is an inclined end One end is bigger than the other, so the height of the tail of the light source lamp 4 is reduced, so that the front of the light source lamp 4 moves upward around its support 21, changing the inclination angle of the light source lamp 4, otherwise, push the adjustment lever 16" inward, and the other The effect is opposite, and the purpose of adjusting the distance of irradiation is finally achieved. After the adjustment, you can pass the threading pin (no mark on the picture) through the hole on the corresponding threading pin seat and adjust the hole on the 16″ to lock the position.

Figure 10 is a reflector tilting adjustment mechanism, the tilting part is similar to Figure 5, the difference is that this solution is also a split type, which is similar to Figures 6, 7, 8, and 9. The lampshade 7, the lamp group 8, the lamp wire 12, the housing 6, the light source lamp mounting base 15, the light source lamp 4, and the light channel 20 are the same as those described above, and the different rear cover 13 and reflector 1 can be adjusted by adjusting the screw 16'"To adjust the inclination, the upper end of the back cover 13 is pivotally connected with the housing 6, and there is a rectangular groove at the lower end of the back cover 13, which should be able to pass the thick head of the adjustment screw 16 as the criterion. The lower end of 6 is provided with a support 30 at the corresponding place, and there are nuts and adjusting screw 16 to match, adjusting rod 16 "" is the screw adjusting rod that is thick in the front and thin in the rear, (also can use the same thick screw to adjust the rod, the middle adds A positioning nut is enough) When the adjustment lever 16 ^,,, is pushed against the back cover 13 by the end of the joint of the thick head and the thin head of the lever, the tilt position of the back cover 13 will be changed, thus changing the reflective The relative inclination angle between the mirror 1 and the light source lamp 4 achieves the purpose of adjusting the irradiation distance. After adjustment, tighten the adjustment nut 14" to fix the device.

The above six schemes shown in Figs. 5-10 all have invisible reflective lighting devices with adjustment mechanisms. Obviously, those skilled in the art can also make various changes, for example, automatic adjustment mechanisms can also be used, such as Known electromagnetic formula etc. But these changes all belong to the protection scope of the claims of the present invention. In a word, these adjustment structures have various changes, but their adjustment purposes are all the same, so the invisible reflective lighting device can be in various adjustment forms, so it will not be explained. Its various adjustment types can also be selected in combination with each other to make an adjustment mechanism with simple structure and convenient use. In addition, from the appearance of the above various lighting devices, they are also different, which shows that their appearance shapes can be varied, in other words, their appearance shapes can be made into various shapes according to actual needs. Industrial applicability

In summary, compared with the prior art, the invisible reflective lighting device has changed the traditional direct The way of lighting, this reflection, covers the dazzling strong light produced by the light, no matter people look at the lighting device from the illuminating side or the illuminated side and other directions, it is always like holding a flashlight and only shining on others. Like myself, I only see the illuminated object illuminated by the spotlight, without any dazzling feeling, let alone the problem of glare. Unless within the range of the light beam 10, from a low place to a high place, and look at the lighting device with the same slope (referring to the slope of the beam irradiation), there will be a dazzling feeling. No dazzling feeling. Take the pedestrian at the lowest position as an example. He is more than one meter tall and is generally higher than the installation position of the headlights. When walking, his eyes are looking at objects parallel to the front, and vehicles coming from the opposite direction usually cause dazzling Within the distance, generally the same slope as the light will not be produced, so there will be no dazzling feeling, and for other vehicles with higher heights, there will be no glare problem. Therefore, the present invention has fundamentally solved the dazzle problem of light, just because of this, can also change the high and low beam control device of modern car lamp, just as shown in Figure 1, high beam 9 and low beam 10 can open simultaneously, There is no need to change its control device. The one is to reduce the burden of manipulation, and the other is to expand the irradiation range of the light to illuminate the road brighter, which is more beneficial to driving. Obviously, a light beam (such as high beam or low beam).

The device can also be provided with an adjustment mechanism, which can adjust the distance of the irradiated light as required to achieve a better irradiating effect. Therefore, the present invention is an optimal solution to the problem of glare of lights, fundamentally solves the problem of glare of lights, and has simple structure, convenient manufacture, convenient use, particularly good effect, and has high promotion and use value , not only can be used for lighting on vehicles, but also can be used in other fields that require non-glare lighting.
