Abstract
Disclosed herein is a method of controlling operation of at least one light-emitting system including at least one light-emitting element. The method includes: a) monitoring at least temporarily, at least one electrical parameter of the light-emitting element; b) evaluating the electrical parameter and verifying if the electrical parameter meets at least one predetermined criterion; and c) taking at least one safeguard action depending on the outcome of step b).
Claims17
A method of controlling operation of at least one light-emitting system comprising at least one light-emitting element, the method comprising:
- monitoring, at least temporarily, at least one electrical parameter of the light-emitting element;
- evaluating the electrical parameter and verifying if the electrical parameter meets at least one predetermined criterion by forming a time derivative of measurements of the electrical parameter and evaluating whether the time derivative of the electrical parameter exceeds a threshold value;
- and
- taking at least one safeguard action depending on the outcome of said evaluating, wherein the safeguard action comprises one of maintaining a constant power supplied to the light-emitting element or reducing a power supplied to the light-emitting element.
A light-emitting system comprising at least one light-emitting element, the light-emitting system being configured for performing a method comprising:
- monitoring, at least temporarily, at least one electrical parameter of the light-emitting element;
- evaluating the electrical parameter and verifying if the electrical parameter meets at least one predetermined criterion by forming a time derivative of measurements of the electrical parameter and evaluating whether the time derivative of the electrical parameter exceeds a threshold value;
- and
- taking at least one safeguard action depending on the outcome of said evaluating and verifying, wherein the safeguard action comprises one of maintaining a constant power supplied to the light-emitting element or reducing a power supplied to the light-emitting element.
