Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of spotlight illumination, and particularly relates to a xenon lamp output confocal adjustment device. Background Art
[0002] Xenon lamps are widely used in the field of optical equipment. They have the advantages of high brightness and wide wavelength range, which can reach 100nm - 2500nm. Their luminous effect can even rival that of sunlight, making them suitable as light sources for some optical detection equipment. The interior of a xenon lamp is filled with xenon gas. Under the ionization of electrodes, a high-brightness light-emitting point will be formed between the cathode and the anode. With the help of optical lenses, the radiation of the point light source can be introduced into the optical equipment, together with some optical lenses such as parabolic mirrors and spherical mirrors.
[0003] For a xenon lamp device using a parabolic mirror to guide light, it is necessary to align the focus of the parabolic mirror with the light-emitting point to output high-quality parallel light. Otherwise, the output light will diverge. Thus, an adjustment device for the focus and the light-emitting point has emerged.
[0004] In terms of aligning the focus with the light-emitting point, some existing adjustment devices often use fixed optical lenses and adjust the three translational degrees of freedom of the X, Y, and Z directions of the xenon lamp to align the focus. However, the xenon lamp generates a large amount of heat. Not only are there fixed devices such as electrodes and cables on the periphery, but there are often large-sized heat dissipation devices, which will bring no small trouble to the design of the xenon lamp adjustment device.
[0005] Currently, there are many inconveniences in the design of the confocal device for the xenon lamp and the lens. When directly adjusting the xenon lamp, the heat dissipation device, support structure, and cables of the xenon lamp need to move together with the xenon lamp adjustment device. First, this will result in a large-sized adjustment mechanism design, which is not conducive to the miniaturization of the equipment. Second, the adjustment mechanism is set around the lamp bulb, which will occupy the output surface of the light source, making it difficult to place the light-guiding lens. Third, the adjustment mechanism design is relatively complex and needs to consider both a small volume and high rigidity. Fourth, adjusting the xenon lamp requires the connection cables of the electrodes to move with it, which is not very safe. Summary of the Invention
[0006] The purpose of the utility model is to provide a xenon lamp output confocal adjustment device to achieve the technical effect of aligning the focus of the parabolic mirror with the light-emitting point of the xenon lamp and outputting high-quality parallel light.

The phrase "in an embodiment" appearing throughout this specification does not necessarily refer to the same embodiment.
[0033] Figure 1 The structural schematic diagram of the xenon lamp output confocal adjustment device in an embodiment of the present utility model is shown.
[0034] As Figure 1 shown, in an embodiment of the present invention, the structure of the xenon lamp output confocal adjustment device is shown, including: a xenon lamp 10, a first electrode 20, a second electrode 30, an optical lens 40, a lens mounting base 50, a three-dimensional adjustment bracket 60, a first wire 70, and a second wire 80. The xenon lamp 10 is connected to the first electrode 20 and the second electrode 30; the optical lens 40 is fixed on the lens mounting base 50; the lens mounting base 50 is fixed on the three-dimensional adjustment bracket 60.
[0035] Figure 2 The structural schematic diagram of the xenon lamp in an embodiment of the present utility model is shown.
[0036] As Figure 2 shown, in an embodiment of the present utility model, the xenon lamp 10 has two electrodes, namely an anode 11 and a cathode 12, which are approximately symmetrically distributed at both ends relative to the center of the light-emitting point.
[0037] As Figure 1As shown, the cathode 12 of the xenon lamp 10 is fixedly connected to the first electrode 20. The side of the first electrode 20 is provided with a peripheral mounting hole, which can be fixed to the peripheral fixing structure of the xenon lamp 10, and the other side is fixed to the first wire 70; the other end of the xenon lamp is the anode 11, and the anode 11 is fixed to the second electrode 30 and is not rigidly connected to any surrounding structure again. One side of the second electrode 30 is connected to the second wire 80. The fixed connection between the first electrode 20 of the xenon lamp 10 and the peripheral device ensures that the xenon lamp 10 cannot move. After the second electrode 30 is fixedly connected to the anode 11 of the xenon lamp, it forms an integral body with the body of the xenon lamp 10. The xenon lamp 10 is equivalent to being fixed at one end and cantilevered at the other end. This is done to avoid deformation and fragmentation of the bulb body caused by both the cathode 12 and the anode 11 of the bulb being fixed to the peripheral device. Thus, the function of fixing the xenon lamp 10 is achieved. Therefore, for the output adjustment of the xenon lamp 10, only the optical lens 40 needs to be adjusted so that its focus needs to coincide with the light-emitting point of the xenon lamp, achieving the effect of outputting a high-quality parallel light.
[0038] In this embodiment, the optical lens 40 is a parabolic mirror and can be fixedly connected to the lens mounting base 50 by any one of gluing, welding, screws, clamping, etc. Obviously, the optical lens 40 can be any required type such as a parabolic mirror, a spherical mirror, a transmission lens, etc. The common feature of these optical lenses is that the input end has a focus, and the focus needs to coincide with the light-emitting point of the xenon lamp. The side of the lens mounting base 50 is provided with mounting holes, and this side is fixed to the three-dimensional adjustment frame 60 by screws to achieve convenient and quick installation. Then, through the three-dimensional adjustment bracket 60, the optical lens 40 can be adjusted in the X-axis, Y-axis, and Z-axis directions.
[0039] Figure 3 The schematic structural diagram of the three-dimensional adjustment frame in an embodiment of the present invention is shown.
[0040] As Figure 3 shown, in an embodiment of the present invention, the three-dimensional adjustment frame 60 has knobs 61, 62, and 63. The function of the knobs is to adjust the position of the lens mounting base 50 by operating the knobs. The knob 61 can adjust in the X-axis direction; the knob 62 can adjust in the Y-axis direction; the knob 63 can adjust in the Z-axis direction. The adjustment of the position of the lens mounting base 50 in space will drive the adjustment of the position of the optical lens 40 fixed on the lens mounting base 50. Thus, the X-axis, Y-axis, and Z-axis of the three-dimensional adjustment frame 60 can be adjusted by adjusting the knobs 61, 62, and 63, and further, the translation of the parabolic mirror 40 in the X, Y, and Z directions can be adjusted. The rotational degrees of freedom of the lens 40 in the RX, RY, and RZ directions are ensured through machining and installation.
[0041] After the xenon lamp 10 is lit, the focus of the parabola is made to coincide with the light-emitting point of the xenon lamp by operating the knobs 61, 62 and 63 of the three-dimensional adjustment frame 60, thereby outputting high-quality parallel light.
[0042] The side of the three-dimensional adjustment frame 60 is provided with a mounting hole 64, and the side is fixed to the lens mounting seat 50 by screws, so as to realize the operation of fixing the lens mounting base 50 on the three-dimensional adjustment frame 60.
[0043] Figure 4 A schematic diagram of the electrode structure in an embodiment of the utility model is shown.
[0044] like Figure 4 As shown, in one embodiment of the utility model, a through hole 22 for penetrating the xenon lamp electrode is provided in the middle of the first electrode 20, and slots are provided on both sides of the center of the through hole. One end of the slot passes through the electrode, and the other end does not pass through. The end that does not pass through is provided with an electrode locking hole 23. When locked, the slot deforms to clamp the xenon lamp 10 to fix the xenon lamp 10. Here, the through hole and the electrode are clearance-matched. In this embodiment, the size of the gap is usually 0.05mm to 0.1mm. If the gap is too large, the electrode will deform too much. Obviously, the second electrode has the same locking structure and principle as the first electrode. After the first electrode 20 and the second electrode 30 are locked and fixed to the xenon lamp 10, the first wire 70 and the second wire 80 are fixed to the cathode 12 and the anode 11 respectively.
[0045] The first electrode 20 is provided with a peripheral mounting hole 21 on the side thereof, which is fixed to the peripheral structure of the xenon lamp by screws. For safety reasons, the fixation with the peripheral structure here must ensure insulation from the cathode 12, the first electrode 20 and other peripheral structures (i.e., conductive structures, such as AC power lines, grounding lines, metal water pipes, etc.). The second electrode 30 and the anode 11 are freely cantilevered relative to the cathode 12, i.e., they are not fixed in position, wherein a safety gap is provided between the second electrode 30 and the anode 11 and the other peripheral structures to prevent the high voltage of the anode 11 from breaking through the air and achieving conduction with the other peripheral structures through the air.
[0046] This utility model patent optimizes many problems existing in the design of the co-point of the xenon lamp's light-emitting point and the focal point of the light-guiding lens to a certain extent. This solution fixes the xenon lamp and adjusts the position of the lens, so there is no need to set an adjustment displacement device around the xenon lamp. The xenon lamp has higher flexibility in designing a heat dissipation device and placing the light-guiding lens; the xenon lamp's fixation is more simplified, and there is no need to consider the rigid and stable connection issues with the adjustment mechanism under the conditions of heat dissipation device, electrode cable dragging, and lens installation; without an adjustment mechanism, the rigid and stable connection between the xenon lamp and the mounting plate is easier; the three-dimensional adjustment mechanism of the lens and the rigid and stable connection design of the lens are simplified. This technical solution abandons the operation of adjusting the xenon lamp, and adjusts the lens so that the focal point of the lens coincides with the light-emitting point of the xenon lamp, thereby achieving the purpose of outputting a high-quality parallel light, simplifying each structure and making it more flexible.

It is obvious to those skilled in the relevant art that various combinations, modifications and changes can be made thereto without departing from the spirit and scope of the present invention. Therefore, the breadth and scope of the present invention disclosed herein should not be limited by the exemplary embodiments disclosed above, but should only be defined according to the attached claims and their equivalents.
