Referring to fig. 1-4, there is provided a lighting device 1, said lighting device 1 comprising:
a plurality of small light sources, each of which emits white light and can be independently controlled to be switched on and off;
a color wheel 3, which is installed at the emitting ends of the small light sources, wherein the color wheel 3 is provided with a plurality of light filtering parts, and the plurality of light filtering parts and the plurality of small light sources are in one-to-one correspondence, so that the white light emitted by each small light source emits light rays with corresponding wave bands after passing through the corresponding light filtering part;
the light filtering parts in the plurality of light filtering parts are different from each other so as to transmit light rays with different wave bands.
Taking holographic 3D printing as an example, the same attribute is set for the same element in the photo model during printing process, and different elements have different attributes, that is, the same element will be displayed under the same wavelength band illumination, but the different elements will not be displayed under the wavelength band. For example, in a holographic 3D printed photo of a building, a wall is the same element, a water pipe network line is the same element, all contents in the photo can be presented under the irradiation of white light, and if the irradiation of an A wave band is adopted, only the wall is displayed; if B wave band irradiation is adopted, only the water outlet pipe network cable is displayed; if the A, B wave band is adopted for irradiation, the cavity and the water pipeline are displayed simultaneously.
The single illumination device 1 is provided with a plurality of small light sources emitting white light, the white light is mixed light, the light emitted by each small light source is processed by the light filtering parts and then transmits light with corresponding wave bands, the obtained light wave bands of each light filtering part are different, for example, a light ray with an A wave band is obtained after one light filtering part, and a light ray with a B wave band is obtained after the other light filtering part, so that the filtering setting of the single color wheel 3 is richer, and the use requirements of users can be better met.
If the light rays emitted after passing through the light filtering part are still white, all models in the 3D holographic photo are displayed; if one of the small light sources is turned on, the light of a specific waveband is obtained, or more than two of the small light sources are turned on, only the part which can be displayed under the specific waveband or the specific waveband is displayed in the 3D holographic photo. Therefore, the 3D model display part can be directly and independently observed on the premise of not changing the observation direction without being interfered by other content parts, and the trouble of mutual interference of the structures during model display can be conveniently and effectively solved.
The same lighting device 1 may be configured with two or more color wheels 3, the filtering portions of the color wheels 3 are arranged differently, which means that the wavelength bands of the filtering portions are different, for example, one color wheel 3 has the filtering portions of a wavelength band and a wavelength band B, and the other color wheel 3 has the filtering portions of a wavelength band B and a wavelength band C, each color wheel 3 may be generally provided with a white filtering portion to obtain a white light source, and the other filtering portions may be arranged according to common use situations. The color wheel 3 is detachably assembled with the lighting device 1, so that a user can replace the color wheel 3 at any time according to the use requirement, for example, the user can replace and install the color wheel 3 according to the known information of the holographic 3D printed photo to be applied.
In some embodiments, the lighting device 1 includes a casing, which may be a common flashlight shape as a whole, and a control circuit component and a power circuit component electrically connected to the plurality of small light sources are installed in the casing (for example, a cylindrical portion), and related circuit connections belong to the prior art and are not described herein; the slant expansion of casing front end is loudspeaker form, casing front end terminal surface is provided with a plurality of little light sources, 3 lid of colour wheel close install in on the casing front end terminal surface. The color wheel 3 can be covered at the front end of the shell by adopting common modes such as threaded connection, clamping connection or close fit, and the light filtering parts on the color wheel 3 correspond to the small light sources one by one.
The light filtering part can be realized by common light filtering pieces, corresponding hole positions are arranged on the color wheel 3, the light filtering pieces are fixed at the hole positions in a bonding, clamping or fastening way, and the like, and white light emitted by the small light source can emit light rays with corresponding wave bands after passing through the light filtering pieces.
If white light is obtained after passing through the light filtering portion, the light filtering portion may be a through hole disposed in front of the corresponding small light source, and light emitted from the small light source is emitted from the through hole without being blocked. The small light source may be a halogen lamp, an LED lamp, a xenon lamp, or the like, but is not limited thereto.
According to the lighting device 1, a lighting method for a holographically 3D printed photograph 2 is provided, in which corresponding elements of the holographically 3D photograph are set to have the same attribute during printing, and the attribute is relative to whether the corresponding elements under different wave bands of light are displayed or not, for example, the color of the same object is set to be the same during editing a model before printing, the photograph model is fully displayed under the irradiation of white light, the elements with the same attribute (such as water pipes and network lines in a building model) in the model are displayed under the irradiation of the light of the corresponding wave bands, and the other elements with different attributes are not displayed at this time.
Referring to fig. 1-4, with the lighting device 1 of any of the foregoing embodiments, the corresponding small light source is turned on as needed, so that the holographic 3D photo shows the content that can be displayed under the light of the corresponding wavelength band. If only a single small light source in the lighting device 1 is turned on, light of a single wavelength band (color) is emitted, i.e. only objects corresponding to the single light source wavelength band (or color) are displayed; when a plurality of small light sources in the illumination device 1 are used for illumination, mixed light of a plurality of light source wavelength bands (or colors) is transmitted, and objects corresponding to the mixed wavelength bands (or colors) can be displayed.
Specifically, in fig. 1, white light is transmitted from the lighting device 1 after passing through the color wheel 3, and all the contents in the holographic 3D photo are displayed; fig. 2 shows the light of a wave band a transmitted from the lighting device 1 after passing through the color wheel 3, and only the elements that can be displayed under the irradiation of the light of a wave band a are displayed in the holographic 3D photo; fig. 3 shows the B-band light transmitted by the lighting device 1 after passing through the color wheel 3, and only the elements that can be displayed under the irradiation of the B-band light are displayed in the holographic 3D photo; in fig. 4, light rays in A, B wavelength band are transmitted after passing through the color wheel 3 in the lighting device 1, and elements displayed under the irradiation of light rays in A, B wavelength band are displayed in the holographic 3D photo.
