It should be understood that the structures, ratios, sizes, and the like shown in the drawings and described in the specification are only used for understanding and reading the present disclosure, and are not used for limiting the limit of the present disclosure, so that the present disclosure is not technically significant, and any structural modification, ratio change or size adjustment should still fall within the scope of the present disclosure without affecting the efficacy and attainment of the present disclosure.
Example 1
As shown in fig. 1, the schematic diagram of optical treatment devices for increasing energy density or output power is shown, and the optical treatment device includes an optical path system composed of a light source, a reflector, a light outlet, a spectrum filtering component and a light guide crystal, wherein the light outlet is provided with a light beam shaping component, a light beam generated by the light source sequentially passes through the reflector, the light outlet, the spectrum filtering component, the light guide crystal and the light beam shaping component, and the light beam generated by the light source is intense pulse light.
The light treatment device shapes the light of the light outlet by arranging the light beam shaping component on the light outlet, so that the light can be converged to a smaller range, and further the light energy density or the output power on the treatment surface is improved.
Under the condition of not adopting a light beam shaping component, the action size of a light guide crystal of the light treatment device can be reduced, the area of the light guide crystal is smaller than that of the light outlet, and the light power density or energy density output is improved.
As preferred embodiments, the light beam shaping component can be a micro lens array, the micro lens array focuses the light beam irradiated on the surface to form a dot matrix output, strong points are formed on the whole treatment surface, as shown in FIG. 2, when the light beam shaping component is the micro lens array, each micro lens changes the emitting direction of the light beam irradiated on each area to realize the focused output, as shown in FIG. 3, the light intensity diagram of the treatment surface under the action of the micro lens array is that the light intensity diagram has the maximum light beam focusing on the central axis of the micro lens array and gradually weakens away from the central area.
In a specific implementation, the microlens array can be an M x N array matrix (M and N are integers larger than 0), each lens array can be arranged in parallel, and can be arranged in a crossed way with fixed angle difference.
In a specific implementation, the light source is any type light source, namely a pulse xenon lamp.
In a specific implementation, the beam shaping component and the light guide crystal are connected with each other, and the specific beam shaping component and the light guide crystal are made of the same material, preferably sapphire material. Has good light guiding and heat conducting performance.
As preferred embodiments, the beam shaping component is removably connected to the light guide crystal, which allows the light therapy device to be used for a variety of treatments.
Example 2
Referring to fig. 4, a schematic diagram of a principle of optical treatment devices for increasing energy density or output power is provided according to the present invention, and as shown in the figure, the optical treatment device includes an optical path system composed of a light source, a reflector, a light outlet, a spectrum filtering component and a light guide crystal, a light beam shaping component with light beam focusing capability is further disposed between the spectrum filtering component and the light guide crystal, and a light beam generated by the light source sequentially passes through the reflector, the light outlet, the spectrum filtering component, the light guide crystal and the light beam shaping component.
An optical path system in an existing phototherapy device based on intense pulsed light is composed of a reflector, a light source, a light outlet, an optical filter and a light guide crystal, because output light has a large divergence angle, and fixed distances exist between the light guide crystal and the light outlet, in order to ensure the better operation of the system, light of a common light outlet can not irradiate the outside of the light guide crystal after passing through the light filter, and therefore the area of the light outlet is obviously smaller than that of the light guide crystal.
In the embodiment, the light beam shaping assembly is arranged behind the optical filter, and because the light beam shaping assembly has the light beam focusing capacity, on the existing basic light guide crystal, the light power/light energy density can be further improved by steps by obtaining the illumination radiation of a larger light outlet.
As a preferred embodiment, the beam shaping component is a lens or a prism with beam focusing capability, such as a focusing lens.
In addition, the beam shaping component may also be a cylindrical mirror, for example, a fresnel lens may be used.
In specific implementation, the light source is any type light source including XeCl excimer light source, LED light source and pulse xenon lamp.
In specific implementation, the technical scheme provided by the embodiment can be applied to intense pulse light treatment of vascular diseases. In the strong pulse light treatment of vascular diseases, the optical power density of 500nm-650nm can only reach 10J/cm if the prior technical scheme is adopted2And the contact area of the light guide crystal and the skin is small, and is usually only 2cm2If the scheme of the embodiment is adopted, the area of the light outlet can be greatly increased, steps are carried out to obtain larger power/energy density output, steps are carried out to improve the treatment speed and the treatment effect, or the area of the light outlet is not changed, the light of the light outlet is directly gathered and output, the improvement of the light power density can also be obviously obtained, preferably, in the independently-functional intense pulse light treatment, the light outlet mode is selected to be expanded, and the energy output with larger power density is obtained through the light beam shaping assembly.
In addition, the invention is considered to be applied to other scenes, such as compatible blood vessel treatment, depilation, skin rejuvenation treatment and other intense pulse light treatments. Therefore, in order to improve the treatment range of the treatment device, the light beam shaping component can be arranged between the spectral filtering component and the light guide crystal in a pluggable mode, and whether the light beam shaping component is applied or not is determined according to treatment needs. For example, in the blood vessel treatment of 500nm-650nm, the light beam concentration treatment is needed for the special application wavelength, and then the light beam shaping component is inserted into the light treatment device; in the unhairing treatment of 750-950nm, the light beam shaping component is pulled out of the light treatment device without any treatment on the light beam.
Example 3
In the prior art, because of the lower optical power density, the treatment is usually performed in a manner that dose integration is achieved with a longer treatment time, such as 50mw/cm2Is irradiated for 10s with an output optical power density of 25mw/cm2The treatment dose is equal when the output optical power density of 20s is irradiated, but this causes a problem that the treatment time becomes long.
In the existing ultraviolet light treatment, the light path thereof is a reflecting shade, a light source, a light outlet and a treatment window. The optical power density storage depends on the luminous intensity of the light source, and generally, the light source with larger volume and higher input voltage has higher output power, but the oversize and the overhigh voltage bring the risks of inconvenient operation and equipment failure.
Therefore, as shown in fig. 5, the present embodiment provides a schematic diagram of optical treatment devices for increasing energy density or output power, and as shown in the figure, the optical treatment device includes an optical path system composed of a light source, a reflector, a light outlet, and a treatment window, a light beam shaping component having a light beam focusing capability is further disposed between the light outlet and the treatment window, a light beam generated by the light source sequentially passes through the reflector, the light outlet, the light beam shaping component, and the treatment window, wherein the light beam generated by the light source is ultraviolet light.
The embodiment arranges light beam shaping components between the treatment window and the light outlet, thereby realizing the improvement of output light intensity by enlarging the size of the light outlet, and realizing the output of higher optical power density by carrying out light beam concentration through the light beam shaping components.
Wherein, the beam shaping component is a Fresnel lens.
It will be appreciated by those skilled in the art that modifications and variations can be made to the disclosed embodiments without departing from the spirit and scope of the invention, and therefore, is equivalent to modifications and variations that would be apparent to those skilled in the art without departing from the spirit and scope of the invention as disclosed in the appended claims.
