Example 1
As shown in fig. 1 to 3, a laser flashlight includes a flashlight housing 100, a laser 1, an optical lens set 2 and a wavelength conversion component are disposed in the flashlight housing 100, the laser 1 and the optical lens set 2 correspond to each other, so that a laser beam of the laser 1 or a light beam after being acted by the wavelength conversion component can be incident on the optical lens set 2, the wavelength conversion component is movably disposed between the laser 1 and the optical lens set 2, the wavelength conversion component includes a wavelength conversion region, a non-wavelength conversion region and a movable mechanism 3, the wavelength conversion region is used for converting a laser emitted by the laser 1 into at least a laser, the non-wavelength conversion region is used for directly transmitting the laser, and the movable mechanism 3 is used for adjusting a relative position of the wavelength conversion component and the laser so that the laser emitted by the laser can selectively irradiate the wavelength conversion region or the non-wavelength conversion region.
It can be understood that in this embodiment, a movable wavelength conversion component is added between the laser 1 and the optical lens group 2, and a wavelength conversion region and a non-wavelength conversion region are disposed on the wavelength conversion component, where the wavelength conversion region has a function of converting laser light emitted by the laser into laser light, and can perform wavelength conversion on the laser beam from the laser 1, and the unconverted laser light and the laser light are mixed to form illumination light, so that the illumination function is realized, and the non-wavelength conversion region directly transmits the laser light to the optical lens group 2, so that ignition laser light can be generated to the outside. In use, the wavelength conversion region and the non-wavelength conversion region can be selectively corresponding to the laser 1 along with the movement of the movable mechanism 3, so that the switching of the lighting function and the ignition function can be realized. That is, when the flashlight is required to project illumination light outwards, the user can manually operate the movable mechanism 3 to make the wavelength conversion region face the laser 1, so that the laser light of the laser 1 irradiates the wavelength conversion region and the illumination light is further projected outwards from the optical lens set 2; similarly, when the flashlight is required to realize the ignition function, a user can manually operate the movable mechanism 3 to enable the non-wavelength conversion region to be opposite to the laser 1, so that laser beams of the laser 1 penetrate through the non-wavelength conversion region and then are emitted outwards from the optical lens group 2, and the laser ignition function can be realized after the laser beams with high energy density are irradiated to inflammable substances due to high laser energy density. Therefore, the scheme of the invention realizes wavelength conversion and light transmission treatment aiming at the laser 1 by controlling the movement of the movable mechanism 3 in the laser flashlight to movably switch the positions of the wavelength conversion region and the non-wavelength conversion region, so that the different functional light switching of the laser flashlight is realized, the operation process is more convenient, the functional switching of the laser flashlight between illumination and ignition is simpler, and the popularization and application of products are more facilitated.
Optionally, the wavelength conversion region is a transmissive phosphor sheet 4, and the transmissive phosphor sheet 4 has a function of converting laser light emitted by the laser 1 into laser light, and can perform wavelength conversion on a laser beam from the laser 1, and the unconverted laser light and the laser light are mixed to form illumination light, so as to realize an illumination function. Further, the transmissive phosphor sheet may be a glass sheet coated with a phosphor layer. Taking a blue laser as an example, the phosphor layer may be a yellow phosphor layer. A part of the blue laser light irradiated onto the yellow fluorescent powder is converted into yellow light by the yellow fluorescent powder, and unconverted blue laser light and yellow light are mixed to form illumination light.
Alternatively, in the present embodiment, as shown in fig. 1 to 3, the optical lens group 2 includes a light receiving lens 13, a light emitting lens 14 and a lens housing 200, the light emitting lens 14 is disposed at an end of the lens housing 200, and the lens housing 200 is movably sleeved on the flashlight housing 100. The laser beam or the light beam after the function of the wavelength conversion component can form laser or high-brightness illumination light before the irradiation of the flashlight after the function of the light receiving lens 13 and the light emitting lens 14. Further, the light receiving lens 13 and the light receiving lens 14 are coaxially disposed.
Further, the laser may be configured as a laser with multiple power steps, for example, when the laser needs to be used for ignition, the laser 1 outputs a laser beam with high power, and at this time, the non-wavelength conversion region of the wavelength conversion component is aligned to the laser 1, and the laser beam transmitted from the non-wavelength conversion region can directly emit the laser with high energy density after passing through the light receiving lens 13 and the light emitting and receiving lens 14, so as to realize the ignition function of the flashlight. For another example, when the laser 1 outputs a laser beam with a lower power, the wavelength conversion region of the wavelength conversion component is aligned with the laser 1, and the illumination light obtained by converting the wavelength conversion region further passes through the light receiving lens 13 and the light emitting lens 14, so that the illumination function of the flashlight can be realized. In addition, the lens housing 200 is movably sleeved on the flashlight housing 100, so that the relative distance between the light emitting lens 14 and the wavelength conversion component or the laser 1 can be conveniently adjusted, for example, when the laser ignition function is to be realized, the laser emitted by the laser 1 can be focused at a certain point by adjusting the position of the lens housing 200, so that the energy density of the laser 1 is most concentrated, inflammables can be ignited rapidly, and when the illumination function is required to be realized, the fluorescent powder layer on the wavelength conversion element is positioned at the combined focal position of the light receiving lens 13 and the light emitting lens 14, and parallel or nearly parallel illumination light can be emitted through the light receiving lens 13 and the light emitting lens 14, and the irradiation distance is the farthest. In other embodiments, the positions of the light receiving lens 13 and the light emitting lens 14 may be adjustable.
Further, as shown in fig. 1 and 5, a sealing silica gel ring 18 is further disposed between the lens housing 200 and the flashlight housing 100, where the sealing silica gel ring 18 performs a sealing function on one hand, and when external force is stopped being applied to the lens housing 200, the sealing silica gel ring 18 performs a positioning function on the lens housing 200 to ensure that the lens housing 200 can be stably sleeved on the flashlight housing 100 when the lens housing 200 is not acted by the external force.
Further, the optical lens set 2 further includes a lens pressing ring 19 and a lens pressing ring 20. The lens press ring 19 is provided with threads, the inner wall of the lens housing 200 and the inner wall of the flashlight housing 100 are also provided with threads, and the threads of the inner wall of the lens housing 200, the threads of the inner wall of the flashlight housing 100 and the threads of the lens press ring 19 are matched. The lens housing 200 is pressed against the flashlight housing 100 by the lens pressing ring 19. The lens pressing ring 20 is also provided with threads matched with the lens housing 200, and the light-emitting lens 14 is pressed on the end part of the lens housing 200 through the lens pressing ring 20.
Further, the optical lens group 2 further includes a lens base 17 for mounting the light receiving lens 13, the lens base 17 is located between the slider 6 and the light emitting lens, a through hole is formed in the middle of the lens base 17, and the light receiving lens 13 is mounted in the through hole of the lens base 17.
Further, the laser flashlight of the present embodiment further includes a heat dissipation housing 300, and the laser 1, the wavelength conversion assembly, and the lens mount 17 are all mounted in the heat dissipation housing 300. Further, the heat dissipation case 300 is installed in the inner cavity of the flashlight housing 100.
Further, as shown in fig. 1 to 4, the non-wavelength conversion region is a transparent glass sheet or a hollowed-out hole 5 formed on the movable mechanism 3. It can be understood that when the laser beam passes through the transparent glass sheet or the hollow hole 5, the transparent glass sheet or the hollow hole 5 does not cause wavelength conversion to the laser beam, so that the laser beam of the laser 1 passes through the transparent glass sheet or the hollow hole 5 and then emits the laser from the optical lens group 2, and the laser ignition function can be realized after the laser with high energy density irradiates flammable substances due to high laser energy density.
Further, as shown in fig. 1 to 4, the movable mechanism 3 includes a slider 6, and the wavelength conversion region and the non-wavelength conversion region are mounted on the slider 6, and the wavelength conversion region and the non-wavelength conversion region are driven by the reciprocal translation of the slider 6 to respectively correspond to the light outlets of the laser 1.
It can be understood that, by installing the sliding block 6 capable of translating in the flashlight housing 100 of the flashlight, after the wavelength conversion region and the non-wavelength conversion region are carried on the sliding block 6, the linear movement of the sliding block 6 can be utilized to synchronously drive the wavelength conversion region and the non-wavelength conversion region to move together, so when the functional light of the flashlight is switched, the sliding block 6 can be controlled to translate reciprocally, the wavelength conversion region and the non-wavelength conversion region can be alternately corresponding to the light outlet of the laser 1, so that the laser beam of the laser 1 can alternately penetrate the wavelength conversion region and the non-wavelength conversion region, the laser flashlight can respectively project illumination light and laser with high energy density to the outside, the function switching of the laser flashlight between illumination and ignition is simpler, and the operation process is more convenient.
Specifically, a through hole (not shown in the figure) is formed in the middle of the slider 6, the transmissive phosphor sheet 4 is laid on the through hole but does not completely block the through hole, and the hollow hole 5 is formed on the part of the through hole which is not blocked, or a phosphor layer is coated on a part of the transparent glass sheet, and the phosphor layer is not coated on the other part of the transparent glass sheet, wherein the area coated with the phosphor layer is a wavelength conversion area, and the area not coated with the phosphor layer is a non-wavelength conversion area.
Further, as shown in fig. 1 to 4, a light homogenizing diffusion sheet 16 is further provided between the transmissive phosphor sheet 4 and the laser 1. After the laser light of the laser 1 is transmitted through the light homogenizing diffusion sheet 16, the laser light can be ensured to be emitted to the transmission type fluorescent powder sheet 4 more uniformly.
Further, as shown in fig. 1 to 4, the movable mechanism 3 further includes a slider base 7, a sliding groove 8 is formed in the slider base 7, and the slider 6 is movably matched in the sliding groove 8.
It will be appreciated that the slider 6 is more stable to translate back and forth in front of the laser 1 under the support of the slider base 7 and the guiding action of the chute 8.
Further, as shown in fig. 1 to 4, the side wall of the slider 6 is arranged with a plurality of spring pins 9, each spring pin 9 is arranged along the translation direction of the slider 6, the inner side of the chute 8 is arranged with a plurality of positioning holes 10, the arrangement direction of each positioning hole 10 corresponds to the arrangement direction of each spring pin 9, that is, the arrangement direction of each positioning hole 10 is consistent with the arrangement direction of each spring pin 9, and the outer ends of the spring pins 9 elastically abut against the positioning holes 10 and can slide into each positioning hole 10 in turn along with the translation of the slider 6.
It will be appreciated that, since the arrangement direction of each positioning hole 10 corresponds to the arrangement direction of each spring pin 9, the spring pins 9 will pass through each positioning hole 10 one by one during the translation of the slider 6 assembled in the chute 8, however, in the static state, the outer ends of the spring pins 9 elastically abut against the positioning holes 10, so that the slider 6 can be temporarily fixed in the chute 8, and thus the transmissive phosphor sheet 4 and the hollow hole 5 (or transparent glass sheet) can be temporarily fixed, and the laser flashlight can maintain to output illumination light or high energy density laser. Similarly, when the functional light of the flashlight needs to be switched to control the sliding block 6 to translate in the chute 8, the spring pin 9 can be easily separated from the positioning hole 10 under the action of external force and slide into the next positioning hole 10 to temporarily fix the sliding block 6 again, so that the outer end of the spring pin 9 can slide into each positioning hole 10 in turn during the translation of the sliding block 6. Due to the structure, the laser flashlight can effectively keep the output of the needed functional light.
Further, the outer end of the spring pin 9 is spherical or hemispherical, so that the outer end of the spring pin 9 can be wound to form an arc surface, the outer end of the spring pin 9 can be more smoothly separated from the positioning hole 10, and the situation that the sliding block 6 cannot move due to the fact that the spring pin 9 is blocked in the positioning hole 10 is avoided.
Further, as shown in fig. 1 to 4, a guide rail groove 11 connected in series to each positioning hole 10 is formed on the inner side of the slide groove 8, and the outer end of the spring pin 9 is slid into the guide rail groove 11.
It will be appreciated that since the outer end of the spring pin 9 slides into the guide groove 11, the guide groove 11 can be used to limit the movement track of the spring pin 9, prevent the spring pin 9 from deviating, and allow the spring pin 9 to remain accurately reached to each positioning hole 10.
