Abstract
The present disclosure relates to an automatic darkening filter 20 which is suitable for darkening for protection from light, in particular from high intensity light, with a simplified set-up, as well as to a set-up device 40 for setting up parameters of a such filter 20. The present disclosure also relates to a system 100, 100′ comprising such an automatic darkening filter 20 and such a set-up device 40, in particular a welding device 110. The present disclosure furthermore relates to a method for setting up such an automatic darkening filter 20 as well as to a headgear 10 with such an automatic darkening filter 20 and to a welding device 110 with such a set-up device 40.
Claims18
An automatic darkening filter, comprising:
- a switchable filter lens comprising at least one switchable shutter switchable between a first state and a second state;
- a filter controller connected to the switchable filter lens to control switching of the switchable filter lens according to a predetermined profile, wherein the filter controller is connected to at least one of the switchable shutters such that the filter controller can:
- (i) send control signals to the at least one switchable shutter to assume any desired state;
- and (ii) receive confirmation signals from the at least one switchable shutter regarding the state of the shutter;
- and
- a filter communication unit connected to the filter controller and configured to:
- (i) receive information from a set-up device of a welding device about the predetermined profile;
- and (ii) send information to the set-up device regarding the state of the at least one switchable shutter;
- wherein the filter is configured to be switched according to the predetermined profile with parameters of the filter.
A welding device, comprising:
- a set-up device configured to provide information about a predetermined profile and including a set-up device communication unit configured to be connected to an automatic darkening filter for transmitting the predetermined profile to the filter, wherein the set-up device is further configured to receive a confirmation message from the automatic darkening filter that switchable shutters of the automatic darkening filter have reached a certain state,
- wherein the filter is configured to be switched according to the predetermined profile with parameters of the filter.
