Method for operating a lamp

摘要

The invention relates to a method for operating a lamp comprising a first light for direct lighting and a second light for indirect lighting of an object, as well as a controller controlling the first and second light emitting means separately, and at least one light sensor is mounted on the lamp and connected to the controller for detecting the amount of light in the area, including any extraneous light. The controller has means to subtract the indirect amount of light reaching the light sensor from the total amount of light coming from the second light emitting means as detected by the light sensor, and the amount of direct light produced by the first light emitting means reaching the light sensor, as well as any existing extraneous light reaching the light sensor, in order to control the lamp, in particular by switching it on or off.

1. A method for operating a lamp comprising a first light emitting means for direct lighting and a second light emitting means for indirect lighting of an object, a controller configured to control the first light emitting means and the second light emitting means separately, and wherein the lamp has at least one light sensor mounted on the lamp to detect the total amount of light in the range of the light sensor including any extraneous light present, wherein the light sensor is connected to the controller, the controller having means to subtract from the total amount of light detected by the light sensor, a calculated amount of light produced by the second light emitting means and the indirect light amount that is incident to the light sensor, and a function of the signals reaching the light sensor, and from the amount of direct light produced by the first emitting means, combined with any extraneous light incident to the light sensor in order to control the lamp, in particular to switch it on or off.
