Description

Technical Field

The utility model relates to the technical field of optical filters, in particular to a radiating structure of an optical filter.

Background

The optical filter is an optical device for selecting a required radiation wave band, and in an intense pulse light therapeutic equipment (IPL), since the photon wave band radiated by a xenon lamp is very wide, and when in treatment, a part of photons need to be filtered out to treat specific symptoms, therefore, the IPL is generally provided with a pluggable optical filter component.

When the filter component is continuously used, the temperature of the filter body and the parts in peripheral contact is increased due to high-intensity strong light radiation for a long time, the service life of the filter can be influenced by the excessively high temperature, and meanwhile, the damage to a human body can be caused when the fixed structure is excessively high in temperature.

The IPL equipment with the replaceable optical filter on the market is relatively insufficient in the aspect of reducing the temperature design of the optical filter and the fixed structure thereof. Most optical filters adopt a natural heat dissipation mode, but the heat dissipation is slow and the effect is poor. And most of the filter fixing devices do not consider effective heat dissipation and prevention of heat transfer to human body-accessible parts.

Therefore, the present utility model provides a heat dissipation structure for an optical filter to solve the above-mentioned problems.
