Sunglasses with a sun protection filter
The invention is based on a sun protection device, in particular sunglasses, with at least one optical sun protection filter comprising at least one liquid-crystal cell, and with at least one sensor unit, which is configured for capturing a solar irradiation. It is proposed that at least one sensor cover, which covers a sensor surface of the at least one sensor unit at least partly and which is, at least partly, at least substantially opaque with respect to an irradiation of a visible light spectrum.
1. Sunglasses with at least one optical sun protection filter comprising at least one liquid-crystal cell and with at least one sensor unit, which is configured for capturing solar radiation, wherein
at least one sensor cover, which covers a sensor surface of the at least one sensor unit and which is opaque with respect to radiation of at least 70% of a spectral range of the visible light spectrum, so that a total of at least 70% of respective radiation is blocked either by absorption, by reflection or by a combination of both, and
the sensor cover and a spectacle frame are one-component injection-molded, so that the at least one sensor cover is embodied at least with a base frame of the spectacle frame as one part, wherein the sensor cover and the base frame are made of the same material.
2. The sunglasses according to claim 1 , wherein the at least one sensor cover covers the sensor surface of the at least one sensor unit entirely.
3. The sunglasses according to claim 1 , wherein the at least one sensor cover is at least translucent with respect to a radiation of at least 70% of a spectral range from 780 nm up to 1100 nm of an infrared-light spectrum, so that wherein at least 70% of a respective radiation is transmitted.
4. The sunglasses according to claim 1 , wherein the at least one sensor cover is at least translucent with respect to a radiation of at least 70% of a spectral range from 100 nm to 380 nm of the UV light spectrum, wherein at least 70% of a respective radiation is transmitted.
5. The sunglasses according to claim 1 , further comprising the spectacle frame, which is configured for accommodating the optical sun protection filter.
6. The sunglasses according to claim 1 , wherein the at least one sensor unit is in at least one operating state configured to at least partly supply an energy for actuating the at least one liquid-crystal cell of the optical sun protection filter.
7. The sunglasses according to claim 1 , wherein the at least one sensor unit comprises at least one photodiode and/or at least one solar cell.
8. A method for producing sunglasses according to claim 1 , wherein at least a portion of the spectacle frame and the at least one sensor cover are produced as the one part in an injection-molding procedure.
9. Sunglasses with at least one optical sun protection filter comprising at least one liquid-crystal cell and with at least one sensor unit, which is configured for capturing solar radiation, wherein
at least one sensor cover, which covers a sensor surface of the at least one sensor unit and which is opaque with respect to a radiation of at least 70% of a spectral range of the visible light spectrum, so that a total of at least 70% of respective radiation is blocked, wherein the total blocked part of the respective radiation is a sum of radiation that is absorbed and radiation that is reflected, and
the sensor cover and a spectacle frame are one-component injection-molded, so that the at least one sensor cover is embodied at least with a base frame of the spectacle frame as one part, wherein the sensor cover and the base frame are made of the same material.
