Abstract
A solar sensor is provided that has microspheres on an interior face of a protective cap or of another radiation-transparent area above a transducer of the sensor. The microspheres scatter the light but at the same time have a much lower damping effect. Preferably, the microspheres are glued to or sealed into the interior face.
Claims10
A solar sensor comprising:
- a transducer;
- a housing having a radiation-transparent area that is located above the transducer;
- and
- microspheres being provided in the radiation-transparent area for scattering light that is emitted through the radiation-transparent area.
1 more element
A solar sensor comprising:
- a transducer for providing a radiation based electrical signal;
- a housing for substantially encompassing the transducer, the housing having a radiation transparent area for allowing incident radiation to pass through the radiation transparent area towards the transducer;
- and
- a plurality of microspheres being provided on an inner surface of at least the radiation transparent area of the housing, the plurality of microspheres dispersing the incident radiation within the housing.
1 more element
A method of manufacturing a solar sensor, the method comprising the steps of:
- providing a housing having a radiation transparent area;
- and
- spraying at least one layer of a plurality of microspheres onto an inner side of the housing within at least the radiation transparent area;
- the microspheres diffusing light, which is radiated towards the housing, within the housing and towards a transducer that generates an electrical signal on the basis of a light intensity of the diffused light.
