Description

Reflector

The present invention relates to a reflection device, and particularly refers to a reflection device used in an optical structure.

In the field of lighting, a general optical mechanism is nothing more than an illuminating device, a reflecting device, a light receiving device, and a projection device. The illuminating device emits at least one light source to the reflecting device, and the light provided by the light source is reflected to the light receiving device through the reflecting device. Afterwards, the light receiving device is designed according to its structure itself, and the light is converted and then transmitted to the designated component, related location, or external environment through the projection device. This is one of the technical aspects of the conventional optical mechanism using related optical elements to emit light.

According to investigation, the relative position of each optical element corresponding to the traditional optical mechanism used in the lighting field needs to be supplemented with precise angle and distance design to optimize the utility of the output light. In the optical mechanism, when each optical element is installed, it is formed by assembling. Therefore, once all the optical components are installed, it is equivalent to that all the optical components have been established and fixed in the predetermined position, and cannot be easily adjusted again, or they have functions such as adjustment.

However, the optical mechanism will inevitably produce errors in the assembly process, causing deviations in the relative positions of related optical components, which in turn affects the light extraction efficiency and results in low product yields. In addition, since all the optical components have been fixed and set up, if you want to re-adjust, you must disassemble all the optical components one by one to search/adjust the error angle, position, distance and other settings, which is quite inconvenient and more necessary. It takes a long time to cost. Here, the structural design of the related optical components of the conventional optical mechanism still has the unsatisfactory fact, which is actually one of the issues that the industry is desperate to improve.

An object of the present invention is to provide a reflection device, which uses an adjustment module to adjust the three-dimensional space of the reflection device to meet the requirements of output light.

The first rod body 110 is disposed on one side of the supporting base 10, and the first base body 111 is disposed on one side of the first rod body 110. The second supporting device 13 includes a second rod body 130 and a second base body 131. The second rod body 130 is disposed on one side of the supporting base 10 and the first rod body 110, and the second base body 131 is disposed on the second rod body. One side of the body 130.

The first adjusting device 12 includes a first adjusting rod 120 and a first elastic member 121. The first adjusting rod 120 passes through a side of the first base 2 to be clamped and screwed to the first base 111. The elastic member 121 is disposed in a first accommodating hole 22 of the inner side 20 of the first base 2 and abuts against the first seat 111. The second adjusting device 14 includes a second adjusting rod 140 and a second elastic member 141. The second adjusting rod 140 passes through the other side of the first base 2 to be clamped and screwed to the second seat body 131.

When a user wants to adjust the reflection device 1 to move in the direction of the first axis A1 and at an angle relative to the third axis A3, the right half of the reflection device 1 (or like the second support device 13, the second support device 13 The position of the second adjusting device 14) is a fixed fulcrum. Rotate the first adjusting rod 120 to rotate counterclockwise to gradually reduce the screw connection range with the first base 111, and then drive the left half of the bearing base 10 ( Or, as the position of the first supporting device 11 and the first adjusting device 12) move in the direction of the first axis A1. At the same time, the first elastic member 121 is in a stretched state due to the movement of the reflecting device 1 according to its own elastic characteristics, that is, as the first supporting device 11 moves away from the first base 2, the elastic member 121 is located on the first base at this time. The compression force between the seat 2 and the first seat body 111 is relatively small.

Similarly, when the user wants to adjust the reflector 1 to move toward the second axis A2', and is at an angle relative to the first axis A1, the second adjustment rod 140 can be adjusted to rotate in the counterclockwise direction to achieve the axial direction. The principle of the displacement effect is the same as that of the first adjusting rod 120 and will not be repeated; wherein, the first axis A1/A1' is the positive/negative direction of the X axis, and the second axis A2/A2' is the positive/negative direction of the Z axis. , The third axis A3/A3' is the positive/negative direction of the Y axis.

According to the thread design between the adjusting rod and the seat body, it can also be done in the opposite way. That is, rotating in the counterclockwise direction means that the adjustment reflector 1 moves closer to the first base 2, and rotating in the clockwise direction means moving away, and it is not limited thereto. Here, the optical path adjustment is performed on the outside of the first base 2 through the reflector 1 of the present invention, and it is not necessary to disassemble all the components combined with the first base 2 to adjust the related components. The problem of the traditional application is really solved. The lack of optical structure in the field of lighting.

Please refer to FIG. 3 and FIG. 4 together, which are schematic diagrams and working diagrams of the first embodiment of the reflection device of the present invention. The reflection device 1 is omitted for the third and fourth diagrams. As shown in the figure, the reflector 1 of the present invention can be combined with a vehicle lamp structure, and further includes a second base 3, and the first base 2 is detachably disposed on one side of the second base 3. At least one illuminating device 4 is arranged on the other side of the second base 3 to provide a first light L1 to the reflecting device 1. A digital micromirror device 5 (Digital Micromirror Device, abbreviated as DMD) is arranged on the other side of the second base 3. The mirror 15 passes through the first axis A1/A1', the second axis A2/A2' or/ And the displacement and angle change of the third axis A3/A3' reflect the first light L1 and generate a second light L2 to the digital micro-mirror device 5. And at least one projection device 6, which penetrates the first base 2 and is opposite to the second base 3. After receiving the second light L2, the digital micromirror device 5 generates a third light L3 to the projection device 6 to be in a plane (not shown). Illustration) Projection.

In detail, the first adjusting rod 120 may directly penetrate one side of the first base 2, and the second adjusting rod 140 may directly penetrate the other side of the first base 2, so that the bearing base 10 is pivoted on the first base 2. Seat 2 inside 20. The projection device 6 is additionally coupled with other fasteners (such as screws, not shown) to be pivoted to the locking holes (such as screw holes, not shown) of the first base 2 corresponding to the fasteners. Or the first adjusting rod 120 may pass through one side of the projection device 6, and the second adjusting rod 140 may pass through the other side of the projection device 6, and the projection device 6 is pivoted to the first base 2 (as shown in the third figure). As shown), the first adjusting rod 120 and the second adjusting rod 140 are used to adjust the axial displacement of the reflecting device 1 at the same time.

Continue to explain the operation mode of the first embodiment of the reflector of the present invention, please refer to the fourth figure, and please refer to the fifth and sixth figures together, which are the top view and the three-dimensional operating view of the first embodiment of the reflector of the present invention . First, the general vehicle lamp structure generates a light path inside, and then projects the light into the external environment, and then goes through the functions of the illuminating device 4, the reflector 15, the digital micro-mirror device 5, and the projection device 6, and displays the relevant information at the designated position. Light pattern. As shown in the fourth figure, the illuminating device 4 is a lighting device (such as a plurality of LEDs) that provides a light source. After the digital micro-mirror device 5 receives the second light L2 (or called reflected light), it is converted into a third light L3 and moves to the projection device 6, and then displays a light pattern outside the vehicle lamp structure. If one of the components of the reflecting device 1, the lighting device 4, the digital micro-mirror device 5, and the projection device 6 is deviated due to external force or during the assembly process, the adjustable structure design of the reflecting device 1 of the present invention can be used in the car. Adjustments can be made outside the lamp. In this way, the light path required by the reflection device 1, the digital micromirror device 5, and the projection device 6 is not subject to deviation, which affects the efficiency of light output. In other words, the conventional optical structure can correctly display light, and the position, angle, distance and other parameter designs of the reflecting device 1, the illuminating device 4, the digital micromirror device 5, and the projection device 6 have been fixedly installed after careful consideration. Therefore, as long as one of the components deviates from the design, the efficiency of the output light is likely to be affected.

In order for the illuminating device 4 to reliably emit the first light L1 to the reflecting device 1, or to allow the digital micromirror device 5 to completely receive the second light L2 reflected by the reflecting device 1, it is necessary to adjust the reflecting device 1 when necessary. The adjustment method is as follows. As shown in the fifth figure, the operation of the first base 2 is omitted and the operation is described in a simplified diagram. When a user wants to adjust the reflection device 1 to move in the direction of the first axis A1, the right half of the reflection device 1 is used as a fixed fulcrum, and the first adjustment rod 120 is rotated in a counterclockwise direction to make it contact with the first seat body. The screw connection range between 111 is gradually reduced, thereby driving the left half of the bearing base 10 to move in the direction of the first axis A1. At the same time, the first elastic member 121 is in a stretched state due to the movement of the reflecting device 1 according to its own elastic characteristics. On the other hand, the second elastic member 141 is in a more compressed state due to the movement of the second supporting device 13 in the first axial direction A1'. Conversely, when the reflector 1 needs to be adjusted to the original position, the first adjusting rod 120 is adjusted to rotate in a clockwise direction, so that the screw connection range with the first base 111 is gradually increased, and the first base 111 Approach the first base 2 (first axis A1'). Moreover, the adjustment principle of the second adjustment device 14 is the same as that of the first adjustment rod 120, and will not be described again.

Furthermore, the fifth figure explains that only the first adjusting device 12 or the second adjusting device 14 is adjusted as a one-way adjustment. If the user needs to displace the bearing seat 10 in the first axial direction A1/A1', the first adjustment device 12 and the second adjustment device 14 can be adjusted separately/at the same time. As shown in the sixth figure, the first adjusting device 12 adjusts the reflecting device 1 to move forward in the direction of the first axis A1, so that the reflecting device 1 moves at an angle with respect to the third axis A3/A3'. Simultaneously/continuously with the second adjusting device 14 adjust the reflector 1 to the first axis A1 direction and move the reflector 1 to the second axis A2/A2' direction, then the final adjustment position of the overall reflector 1 is towards the third The axis is inclined to A3/A3'.

Here, in the assembly process of the general car light structure, the relevant components that need to be installed on the first base 2 and the second base 3 have been installed in appropriate places according to the design requirements; however, the car light structure is in the assembly process , Or the displacement of the internal and external components of the first base 2 and the second base 3 due to external forces causes deviations, and the optical path can be adjusted outside the lamp structure through the reflector 1 of the present invention.

Please refer to FIG. 7, which is an exploded schematic diagram of the second embodiment of the reflection device of the present invention. As shown in the figure, the difference between the second embodiment of the present invention and the first embodiment is that the carrier 10 further includes at least one first screw hole 102 and at least one second screw hole 103. On one side of the groove body 100, at least one first lock member 7 is screwed into the first screw hole 102 to abut the first rod 110 and pivoted on the carrier 10, and the second screw hole 103 is arranged in the second groove body 101 On one side, at least one second locking element 7 ′ is screwed into the second screw hole 103 and abutted against the second rod 130 and pivoted on the supporting base 10.

In other words, when assembling the first supporting device 11 and the second supporting device 13 with the supporting base 10 of the reflecting device 1, the structural design of the first tank body 100 and the second tank body 101 has been used, and the first rod body 110 and the second rod body 110 can be combined. The two rods 130 are positioned axially. In order to more stably install the first supporting device 11 and the second supporting device 13 on the supporting base 10, a first screw hole 102, a second screw hole 103, and a first/second lock 7/7 are added to the second embodiment. 'And other components restrict the displacement of the first support device 11 and the second support device 13 on the bearing base 10 to prevent arbitrary movement and cause loosening.
