Lighting system
First Claim
1. A lighting system comprising:
- a power providing unit for providing power to a lighting device, wherein the power providing unit is operable in different operational modes,the lighting device, wherein the lighting device has a first USB-PD connector,a second USB-PD connector electrically connected with the power providing unit and being adapted to be connected with the first USB-PD connector for generating a connection via which the provided power is receivable by the lighting device,a connection feature determination unit for determining a connection feature value being indicative of a feature of the connection formed by the first USB-PD connector and the second USB-PD connector, wherein the connection feature value indicates the quality of a thermal coupling of the connection, anda controlling system for controlling the lighting system, wherein the controlling system is adapted to control, in which operational mode the power providing unit is operated, depending on the determined connection feature value.

Abstract
The invention relates to a lighting system (1) comprising a lighting device (6) having a first USB-PD connector and a power providing unit, which is preferentially a component of a power providing device (4) and which is operable in different operational modes. A second USB-PD connector is electrically connected with the power providing unit and adapted to be connected with the first USB-PD connector for generating a USB-PD connection (5) via which power and optionally also data are receivable by the lighting device. A connection feature value being indicative of a feature of the connection is determined and the operational mode of the power providing unit is controlled depending on the determined connection feature value. This allows for a reaction on the current connection situation. For instance, if the connection feature value indicates a relatively low thermal coupling, the power providing unit may provide less power.
