The invention relates to the technical field of light filtering sheets, and discloses a powerful heat-dissipation type light filtering sheet assembly. The powerful heat-dissipation type light filtering sheet assembly comprise a frame and a light filtering sheet body, wherein an upper light transmission plate is arranged at the upper end of the frame, and a lower light transmission plate is arranged at the lower end of the frame; the light filtering sheet body is arranged between the upper light transmission plate and the lower light transmission plate; the light filtering sheet body is formedby coiling a flexible light transmission tube; the inner end of the flexible light transmission tube is enclosed while the outer end of the light filtering sheet body communicates with the outside; one independent medium cavity is at least formed in the flexible light transmission tube; a flexible light-transmission insulated belt is arranged in the medium cavity; the medium cavity is divided intoa liquid inlet channel and a liquid outlet channel through the flexible light-transmission insulated belt; the liquid inlet channel communicates with the inner end of the liquid outlet channel; the liquid inlet channel and the liquid outlet channel are internally filled with liquid-stage light filtering mediums; a liquid inlet joint is arranged at the outer end of the flexible light transmissiontube; a liquid outlet joint which is connected with the outer end of the liquid outlet channel is arranged at the outer end of the flexible light transmission tube; and the outer ends of the liquid inlet joint and the liquid outlet joint pass through the frame and extend to the outside of the frame. The powerful heat-dissipation type light filtering sheet assembly disclosed by the invention has the advantages of high heat dissipation performance and long service life.
Description
technical field [0001] The invention relates to the technical field of optical filters, in particular to an efficient heat dissipation type optical filter assembly. Background technique [0002] Optical filters are optical devices used to select the required radiation bands. Optical filters are widely used in the field of medical equipment. For example, infrared physiotherapy equipment uses infrared rays to irradiate parts of the human body, which can improve blood circulation and increase cell phagocytosis. , and then eliminate local swelling, promote inflammation to dissipate, etc.; the infrared range is very wide, from 780nm-14μm, and is divided into near-infrared (code-named IR-A, wavelength 780-1500nm, NIR), mid-infrared (IR-B, 1500 ~6000nm, MIR), far infrared (IR-C, 6000nm~14000nm, FIR), for example, if we need near-infrared rays, we need to filter out mid-infrared and far-infrared rays through filters, or there are both infrared rays and Ultraviolet rays need to be f...
